Title 26—Internal Revenue--Volume 1
PART 1—INCOME TAXES
§ 1.167(a)-8   Retirements.
(a) Gains and losses on retirements. For the purposes of this section the term “retirement” means the permanent withdrawal of depreciable property from use in the trade or business or in the production of income. The withdrawal may be made in one of several ways. For example, the withdrawal may be made by selling or exchanging the asset, or by actual abandonment. In addition, the asset may be withdrawn from such productive use without disposition as, for example, by being placed in a supplies or scrap account. The tax consequences of a retirement depend upon the form of the transaction, the reason therefor, the timing of the retirement, the estimated useful life used in computing depreciation, and whether the asset is accounted for in a separate or multiple asset account. Upon the retirement of assets, the rules in this section apply in determining whether gain or loss will be recognized, the amount of such gain or loss, and the basis for determining gain or loss:
(1) Where an asset is retired by sale at arm's length, recognition of gain or loss will be subject to the provisions of sections 1002, 1231, and other applicable provisions of law.
(2) Where an asset is retired by exchange, the recognition of gain or loss will be subject to the provisions of sections 1002, 1031, 1231, and other applicable provisions of law.
(3) Where an asset is permanently retired from use in the trade or business or in the production of income but is not disposed of by the taxpayer or physically abandoned (as, for example, when the asset is transferred to a supplies or scrap account), gain will not be recognized. In such a case loss will be recognized measured by the excess of the adjusted basis of the asset at the time of retirement over the estimated salvage value or over the fair market value at the time of such retirement if greater, but only if—
(i) The retirement is an abnormal retirement, or
(ii) The retirement is a normal retirement from a single asset account (but see paragraph (d) of this section for special rule for item accounts), or
(iii) The retirement is a normal retirement from a multiple asset account in which the depreciation rate was based on the maximum expected life of the longest lived asset contained in the account.
(4) Where an asset is retired by actual physical abandonment (as, for example, in the case of a building condemned as unfit for further occupancy or other use), loss will be recognized measured by the amount of the adjusted basis of the asset abandoned at the time of such abandonment. In order to qualify for the recognition of loss from physical abandonment, the intent of the taxpayer must be irrevocably to discard the asset so that it will neither be used again by him nor retrieved by him for sale, exchange, or other disposition.
(b) Definition of normal and abnormal retirements. For the purpose of this section the determination of whether a retirement is normal or abnormal shall be made in the light of all the facts and circumstances. In general, a retirement shall be considered a normal retirement unless the taxpayer can show that the withdrawal of the asset was due to a cause not contemplated in setting the applicable depreciation rate. For example, a retirement is considered normal if made within the range of years taken into consideration in fixing the depreciation rate and if the asset has reached a condition at which, in the normal course of events, the taxpayer customarily retires similar assets from use in his business. On the other hand, a retirement may be abnormal if the asset is withdrawn at an earlier time or under other circumstances, as, for example, when the asset has been damaged by casualty or has lost its usefulness suddenly as the result of extraordinary obsolescence.
(c) Basis of assets retired. The basis of an asset at the time of retirement for computing gain or loss shall be its adjusted basis for determining gain or loss upon a sale or other disposition as determined in accordance with the provisions of section 1011 and the following rules:
(1) In the case of a normal retirement of an asset from a multiple asset account where the depreciation rate is based on average expected useful life, the term “adjusted basis” means the salvage value estimated in determining the depreciation deduction in accordance with the provisions in paragraph (c) of § 1.167(a)-1.
(2) In the case of a normal retirement of an asset from a multiple asset account on which the depreciation rate was based on the maximum expected life of the longest lived asset in the account, the adjustment for depreciation allowed or allowable shall be made at the rate which would have been proper if the asset had been depreciated in a single asset account (under the method of depreciation used for the multiple asset account) using a rate based upon the maximum expected useful life of that asset, and
(3) In the case of an abnormal retirement from a multiple asset account the adjustment for depreciation allowed or allowable shall be made at the rate which would have been proper had the asset been depreciated in a single asset account (under the method of depreciation used for the multiple asset account) and using a rate based upon either the average expected useful life or the maximum expected useful life of the asset, depending upon the method of determining the rate of depreciation used in connection with the multiple asset account.
(d) Special rule for item accounts. (1) As indicated in paragraph (a)(3)(ii) and (iii) of this section, a loss is recognized upon the normal retirement of an asset from a single asset account but a loss on the normal retirement of an asset in a multiple asset account is not allowable where the depreciation rate is based upon the average useful life of the assets in the account. Where a taxpayer with more than one depreciable asset chooses to set up a separate account for each such asset and the depreciation rate is based on the average useful life of such assets (so that he uses the same life for each account), the question arises whether his depreciation deductions in substance are the equivalent of those which would result from the use of multiple asset accounts and, therefore, he should be subject to the rules governing losses on retirements of assets from multiple asset accounts. Where a taxpayer has only a few depreciable assets which he chooses to account for in single asset accounts, particularly where such assets cover a relatively narrow range of lives, it cannot be said in the usual case that the allowance of losses on retirements from such accounts clearly will distort income. This results from the fact that where a taxpayer has only a few depreciable assets it is usually not possible clearly to determine that the depreciation rate is based upon the average useful life of such assets. Accordingly, it cannot be said that the taxpayer is in effect clearly operating with a multiple asset account using an average life rate so that losses should not be allowed on normal retirements. Therefore, losses normally will be allowed upon retirement of assets from single asset accounts where the taxpayer has only a few depreciable assets. On the other hand, when a taxpayer who has only a few depreciable assets chooses to account for them in single asset accounts, using for each account a depreciation rate based on the average useful life of such assets, and the assets cover a wide range of lives, the likelihood that income will be distorted is greater than where the group of assets covers a relatively narrow range of lives. In those cases where the allowance of losses would distort income, the rules with respect to the allowance of losses on normal retirement shall be applied to such assets in the same manner as though the assets had been accounted for in multiple asset accounts using a rate based upon average expected useful life.
(2) Where a taxpayer has a large number of depreciable assets and depreciation is based on the average useful life of such assets, then, whether such assets are similar or dissimilar and regardless of whether they are accounted for in individual asset accounts or multiple asset accounts the allowance of losses on the normal retirement of such assets would distort income. Such distortion would result from the fact that the use of average useful life (and, accordingly, average rate) assumes that while some assets normally will be retired before the expiration of the average life, others normally will be retired after expiration of the average life. Accordingly, if instead of accounting for a large number of similar or dissimilar depreciable assets in multiple asset accounts, the taxpayer chooses to account separately for such assets, using a rate based upon the average life of such assets, the rules with respect to the allowances of losses on normal retirements will be applied to such assets in the same manner as though the assets were accounted for in multiple asset accounts using a rate based upon average expected useful life.
(3) Where a taxpayer who does not have a large number of depreciable assets (and who therefore is not subject to subparagraph (2) of this paragraph) chooses to set up a separate account for each such asset, and has sought to compute an average life for such assets on which to base his depreciation deductions (so that he uses the same life for each account), the allowance of losses on normal retirements from such accounts may in some situations substantially distort income. Such distortion would result from the fact that the use of average useful life (and, accordingly, average rate) assumes that while some assets normally will be retired before expiration of the average life, others normally will be retired after expiration of the average life. Accordingly, where a taxpayer chooses to account separately for such assets instead of accounting for them in multiple asset accounts, and the result is to substantially distort his income, the rules with respect to the allowance of losses on normal retirements shall be applied to such assets in the same manner as though the assets had been accounted for in multiple asset accounts using a rate based upon average expected useful life.
(4) Whenever a taxpayer is treated under this paragraph as though his assets were accounted for in a multiple asset account using an average life rate, and, therefore, he is denied a loss on retirements, the unrecovered cost less salvage of each asset which was accounted for separately may be amortized in accordance with the regulation stated in paragraph (e)(1)(ii) of this section.
(e) Accounting treatment of asset retirements. (1) In the case of a normal retirement where under the foregoing rules no loss is recognized and where the asset is retired without disposition or abandonment, (i) if the asset was contained in a multiple asset account, the full cost of such asset, reduced by estimated salvage, shall be charged to the depreciation reserve, or (ii) if the asset was accounted for separately, the unrecovered cost or other basis, less salvage, of the asset may be amortized through annual deductions from gross income in amounts equal to the unrecovered cost or other basis of such asset, divided by the average expected useful life (not the remaining useful life) applicable to the asset at the time of retirement. For example, if an asset is retired after six years of use and at the time of retirement depreciation was being claimed on the basis of an average expected useful life of ten years, the unrecovered cost or other basis less salvage would be amortized through equal annual deductions over a period of ten years from the time of retirement.
(2) Where multiple asset accounts are used and acquisitions and retirements are numerous, if a taxpayer, in order to avoid unnecessarily detailed accounting for individual retirements, consistently follows the practice of charging the reserve with the full cost or other basis of assets retired and of crediting it with all receipts from salvage, the practice may be continued so long as, in the opinion of the Commissioner, it clearly reflects income. Conversely, where the taxpayer customarily follows a practice of reporting all receipts from salvage as ordinary taxable income such practice may be continued so long as, in the opinion of the Commissioner, it clearly reflects income.
(f) Cross reference. For special rules in connection with the retirement of the last assets of a given year's acquisitions under the declining balance method, see example (2) in paragraph (b) of § 1.167 (b)-2.
(g) Applicability. This section applies to property for which depreciation is determined under section 167 (but not under section 168, section 1400I, section 1400L(c), section 168 prior to its amendment by the Tax Reform Act of 1986, Public Law 99-514 (100 Stat. 2121(1986)), or under an additional first year depreciation deduction provision of the Internal Revenue Code (for example, section 168(k) through (n), 1400L(b), or 1400N(d))).
(h) Effective/applicability date —(1) In general. This section applies to taxable years beginning on or after January 1, 2014. Except as provided in paragraphs (h)(2) and (h)(3) of this section, § 1.167(a)-8 as contained in 26 CFR part 1 edition revised as of April 1, 2011, applies to taxable years beginning before January 1, 2014.
(2) Early application of § 1.167(a)-8(g). A taxpayer may choose to apply paragraph (g) of this section to taxable years beginning on or after January 1, 2012.
(3) Optional application of TD 9564. A taxpayer may choose to apply § 1.167(a)-8T as contained in TD 9564 (76 FR 81060) December 27, 2011, to taxable years beginning on or after January 1, 2012, and before January 1, 2014.
§ 1.167(a)-9   Obsolescence.
The depreciation allowance includes an allowance for normal obsolescence which should be taken into account to the extent that the expected useful life of property will be shortened by reason thereof. Obsolescence may render an asset economically useless to the taxpayer regardless of its physical condition. Obsolescence is attributable to many causes, including technological improvements and reasonably foreseeable economic changes. Among these causes are normal progress of the arts and sciences, supersession or inadequacy brought about by developments in the industry, products, methods, markets, sources of supply, and other like changes, and legislative or regulatory action. In any case in which the taxpayer shows that the estimated useful life previously used should be shortened by reason of obsolescence greater than had been assumed in computing such estimated useful life, a change to a new and shorter estimated useful life computed in accordance with such showing will be permitted. No such change will be permitted merely because in the unsupported opinion of the taxpayer the property may become obsolete. For rules governing the allowance of a loss when the usefulness of depreciable property is suddenly terminated, see § 1.167(a)-8. If the estimated useful life and the depreciation rates have been the subject of a previous agreement, see section 167(d) and § 1.167(d)-1.
§ 1.167(a)-10   When depreciation deduction is allowable.
(a) A taxpayer should deduct the proper depreciation allowance each year and may not increase his depreciation allowances in later years by reason of his failure to deduct any depreciation allowance or of his action in deducting an allowance plainly inadequate under the known facts in prior years. The inadequacy of the depreciation allowance for property in prior years shall be determined on the basis of the allowable method of depreciation used by the taxpayer for such property or under the straight line method if no allowance has ever been claimed for such property. The preceding sentence shall not be construed as precluding application of any method provided in section 167(b) if taxpayer's failure to claim any allowance for depreciation was due solely to erroneously treating as a deductible expense an item properly chargeable to capital account. For rules relating to adjustments to basis, see section 1016 and the regulations thereunder.
(b) The period for depreciation of an asset shall begin when the asset is placed in service and shall end when the asset is retired from service. A proportionate part of one year's depreciation is allowable for that part of the first and last year during which the asset was in service. However, in the case of a multiple asset account, the amount of depreciation may be determined by using what is commonly described as an “averaging convention”, that is, by using an assumed timing of additions and retirements. For example, it might be assumed that all additions and retirements to the asset account occur uniformly throughout the taxable year, in which case depreciation is computed on the average of the beginning and ending balances of the asset account for the taxable year. See example (3) under paragraph (b) of § 1.167(b)-1. Among still other averaging conventions which may be used is the one under which it is assumed that all additions and retirements during the first half of a given year were made on the first day of that year and that all additions and retirements during the second half of the year were made on the first day of the following year. Thus, a full year's depreciation would be taken on additions in the first half of the year and no depreciation would be taken on additions in the second half. Moreover, under this convention, no depreciation would be taken on retirements in the first half of the year and a full year's depreciation would be taken on the retirements in the second half. An averaging convention, if used, must be consistently followed as to the account or accounts for which it is adopted, and must be applied to both additions and retirements. In any year in which an averaging convention substantially distorts the depreciation allowance for the taxable year, it may not be used.
§ 1.167(a)-11   Depreciation based on class lives and asset depreciation ranges for property placed in service after December 31, 1970.
(a) In general —(1) Summary. This section provides an asset depreciation range and class life system for determining the reasonable allowance for depreciation of designated classes of assets placed in service after December 31, 1970. The system is designed to minimize disputes between taxpayers and the Internal Revenue Service as to the useful life of property, and as to salvage value, repairs, and other matters. The system is optional with the taxpayer. The taxpayer has an annual election. Generally, an election for a taxable year must apply to all additions of eligible property during the taxable year of election, but does not apply to additions of eligible property in any other taxable year. The taxpayer's election, made with the return for the taxable year, may not be revoked or modified for any property included in the election. Generally, the taxpayer must establish vintage accounts for all eligible property included in the election, must determine the allowance for depreciation of such property in the taxable year of election, and in subsequent taxable years, on the basis of the asset depreciation period selected and must apply the first-year convention specified in the election to determine the allowance for depreciation of such property. This section also contains special provisions for the treatment of salvage value, retirements, and the costs of the repair, maintenance, rehabilitation or improvement of property. In general, a taxpayer may not apply any provision of this section unless he makes an election and thereby consents to, and agrees to apply, all the provisions of this section. A taxpayer who elects to apply this section does, however, have certain options as to the application of specified provisions of this section. A taxpayer may elect to apply this section for a taxable year only if for such taxable year he complies with the requirements of paragraph (f)(4) of this section.
(2) Definitions. For the meaning of certain terms used in this section, see paragraphs (b)(2) (“eligible property”), (b)(3) (“vintage account” and “vintage”), (b)(4) (“asset depreciation range”, “asset guideline class”, “asset guideline period”, and “asset depreciation period”), (b)(5)(iii)( c ) (“used property”), (b)(6)(i) (“public utility property”), (c)(1)(iv) (“original use”), (c)(1)(v) (“unadjusted basis” and “adjusted basis”), (c)(2)(ii) (“modified half-year convention”), (c)(2)(iii) (“half-year convention”), (d)(1)(i) (“gross salvage value”), (d)(1)(ii) (“salvage value”), (d)(2)(iii) (“repair allowance”, “repair allowance percentage”, and “repair allowance property”), (d)(2)(vi) (“excluded addition”), (d)(2)(vii) (“property improvement”), (d)(3)(ii) (“ordinary retirement” and “extraordinary retirement”), (d)(3)(vi) (“special basis vintage account”), and (e)(1) (“first placed in service”) of this section.
(b) Reasonable allowance using asset depreciation ranges —(1) In general. The allowance for depreciation of eligible property (as defined in subparagraph (2) of this paragraph) to which the taxpayer elects to apply this section shall be determined as provided in paragraph (c) of this section and shall constitute the reasonable allowance for depreciation of such property under section 167(a).
(2) Definition of eligible property. For purposes of this section, the term “eligible property” means tangible property which is subject to the allowance for depreciation provided by section 167(a) but only if—
(i) An asset guideline class and asset guideline period are in effect for such property for the taxable year of election (see subparagraph (4) of this paragraph);
(ii) The property is first placed in service (as described in paragraph (e) (1) of this section) by the taxpayer after December 31, 1970 (but see subparagraph (7) of this paragraph for special rule where there is a mere change in the form of conducting a trade or business); and
(iii) The property is either—
( a ) Section 1245 property as defined in section 1245(a) (3), or
( b ) Section 1250 property as defined in section 1250(c).
(3) Requirement of vintage accounts —(i) In general. For purposes of this section, a “vintage account” is a closed-end depreciation account containing eligible property to which the taxpayer elects to apply this section, first placed in service by the taxpayer during the taxable year of election. The “vintage” of an account refers to the taxable year during which the eligible property in the account is first placed in service by the taxpayer. Such an account will consist of an asset, or a group of assets, within a single asset guideline class established pursuant to subparagraph (4) of this paragraph and may contain only eligible property. Each item of eligible property to which the taxpayer elects to apply this section, first placed in service by the taxpayer during the taxable year of election (determined without regard to a convention described in paragraph (c)(2) of this section) shall be placed in a vintage account of the taxable year of election. For rule regarding “special basis vintage accounts” for certain property improvements, see paragraph (d)(2)(viii) and (3)(vi) of this section. Any number of vintage accounts of a taxable year may be established. More than one account of the same vintage may be established for different assets of the same asset guideline class. See paragraph (d)(3)(xi) of this section for special rule for treatment of certain multiple asset and item accounts.
(ii) Special rule. Section 1245 property may not be placed in a vintage account with section 1250 property. Property the original use of which does not commence with the taxpayer may not be placed in a vintage account with property the original use of which commences with the taxpayer. Property described in section 167(f)(2) may not be placed in a vintage account with property not described in section 167(f)(2). Property described in section 179(d)(1) for which the taxpayer elects the allowance for the first taxable year in accordance with section 179(c) may not be placed in a vintage account with property not described in section 179(d)(1) or for which the taxpayer does not elect such allowance for the first taxable year. For special rule for property acquired in a transaction to which section 381(a) applies, see paragraph (e)(3)(i) of this section. For additional rules with respect to accounting for eligible property, see paragraph (e) of this section.
(4) Asset depreciation ranges and periods —(i) Selection of asset depreciation period. The taxpayers books and records must specify for each vintage account of the taxable year of election—
( a ) In the case of vintage account for property in an asset guideline class for which no asset depreciation range is in effect for the taxable year, the asset depreciation period (which shall be equal to the asset guideline period for the assets in such account), or
( b ) In the case of a vintage account for property in an asset guideline class for which an asset depreciation range is in effect for the taxable year, the asset depreciation period selected by the taxpayer from the asset depreciation range for the assets in such account.
(ii) Establishment of asset guideline classes and periods. The asset guideline classes and the asset guideline periods, and the asset depreciation ranges determined from such periods, in effect for taxable years ending before the effective date of the first supplemental asset guideline classes, asset guideline periods, and asset depreciation ranges, established pursuant to this section are set forth in Revenue Procedure 72-10. Asset guideline classes and periods, and asset depreciation ranges, will from time to time be established, supplemented, and revised with express reference to this section, and will be published in the Internal Revenue Bulletin. The asset guideline classes, the asset guideline periods, and the asset depreciation ranges determined from such periods in effect as of the last day of a taxable year of election shall apply to all vintage accounts of such taxable year, except that neither the asset guideline period nor the lower limit of the asset depreciation range for any such account shall be longer than the asset guideline period or the lower limit of the asset depreciation range, as the case may be, for such account in effect as of the first day of the taxable year (or as of such later time in such year as an asset guideline class first established during such year becomes effective). Generally, the reasonable allowance for depreciation of property for any taxable year in a vintage account shall not be changed to reflect any supplement or revision of the asset guideline classes or periods, and asset depreciation ranges, for the taxable year in which the account is established, which occurs after the end of such taxable year. However, if expressly provided in such a supplement or revision, the taxpayer may, at his option in the manner specified therein, apply the revised or supplemented asset guideline classes or periods and asset depreciation ranges to such property for such taxable year and succeeding taxable years.
(iii) Applicable guideline classes and periods in special situations. ( a ) An electric or gas utility which would in accordance with Revenue Procedure 64-21 be entitled to use a composite guideline class basis for applying Revenue Procedure 62-21 may, solely with respect to property for which an asset depreciation range is in effect for the taxable year, elect to apply this section on the basis of a composite asset guideline class and asset guideline period determined by applying the provisions of Revenue Procedure 64-21 to such property. The asset depreciation range for such a composite asset guideline class shall be determined by reference to the composite asset guideline period at the beginning of the first taxable year to which the taxpayer elects to apply this section and shall not be changed until such time as major variations in the asset mix or the asset guideline classes or periods justify some other composite asset guideline period. Except as provided in paragraph (d)(2)(iii) of this section with respect to buildings and other structures, for the purposes of this section, all property in the composite asset guideline class shall be treated as included in a single asset guideline class. If the taxpayer elects to apply this subdivision, the election shall be made on the tax return filed for the first taxable year for which the taxpayer elects to apply this section. An election to apply this subdivision for any taxable year shall apply to all succeeding taxable years to which the taxpayer elects to apply this section, except to the extent the election to apply this subdivision is with the consent of the Commissioner terminated with respect to a succeeding taxable year and all taxable years thereafter.
( b ) For purposes of this section, property shall be included in the asset guideline class for the activity in which the property is primarily used. See paragraph (e)(3)(iii) of this section for rule for leased property. Property shall be classified according to primary use even though the activity in which such property is primarily used is insubstantial in relation to all the taxpayer's activities. No change in the classification of property shall be made because of a change in primary use after the end of the taxable year in which property is first placed in service, including a change in use which results in section 1250 property becoming section 1245 property.
( c ) An incorrect classification or characterization by the taxpayer of property for the purposes of this section (such as under ( b ) of this subdivision or under subparagraph (2) or (3) (ii) of this paragraph) shall not cause or permit a revocation of the election to apply this section for the taxable year in which such property was first placed in service. The classification or characterization of such property shall be corrected. All adjustments necessary to the correction shall be made, including adjustments of unadjusted basis, adjusted basis, salvage value, the reserve for depreciation of all vintage accounts affected, and the amount of depreciation allowable for all taxable years for which the period for assessment of tax prescribed in section 6501 has not expired. If because of incorrect classification or characterization property included in an election to apply this section was not placed in a vintage account and no asset depreciation period was selected for the property or the property was placed in a vintage account but an asset depreciation period was selected from an incorrect asset depreciation range, the taxpayer shall place the property in a vintage account and select an asset depreciation period for the account from the correct asset depreciation range.
( d ) Generally, except as provided in subparagraph (5)(v)( a ) of this paragraph, a taxpayer may not compute depreciation for eligible property first placed in service during the taxable year under a method of depreciation not described in section 167(b) (1), (2), or (3). (If the taxpayer computes depreciation with respect to such property under section 167(k), or amortizes such property, the property must be excluded from the election to apply this section.) (See subparagraph (5)(v)( b ) of this paragraph.) However, if the taxpayer establishes to the satisfaction of the Commissioner that a method of depreciation not described in section 167(b) (1), (2), (3), or (k) was adopted for property in the asset guideline class on the basis of a good faith mistake as to the proper asset guideline class for the property, then, unless the requirements of subparagraph (5)(v)( a ) of this paragraph are met, the taxpayer must terminate (as of the beginning of the taxable year) such method of depreciation with respect to all eligible property in the asset guideline class which was first placed in service during the taxable year. In such event, the taxpayer's election to apply this section shall include eligible property in the asset guideline class without regard to subparagraph (5)(v)( a ) of this paragraph. The provisions of ( c ) of this subdivision shall apply to the correction in the classification of the property.
( e ) If the provisions of section 167(j) apply to require a change in the method of depreciation with respect to an item of section 1250 property in a multiple asset vintage account, the asset shall be removed from the account and placed in a separate item vintage account. The unadjusted basis of the asset shall be removed from the unadjusted basis of the vintage account as of the first day of the taxable year in which the change in method of depreciation is required and the depreciation reserve established for the account shall be reduced by the depreciation allowable for the property computed in the manner prescribed in paragraph (c)(1)(v)( b ) of this section for determination of the adjusted basis of property. See paragraph (d)(3)(vii)( e ) of this section for treatment of salvage value when property is removed from a vintage account.
(iv) Examples. The principles of this subparagraph may be illustrated by the following examples:
( b ) The facts are the same as in ( a ) of this example except that machine B has an unadjusted basis equal to only 65 percent of the total unadjusted basis of machines B through M.
In this case, corporation X must either terminate the machine hour method of depreciation with respect to asset B (since the provisions of subparagraph (5)(v) of this paragraph do not permit the exclusion of the property from the election to apply this section) or otherwise comply with the provisions of subparagraph (5)(v) of this paragraph. (See paragraph (c)(1)(iv) for limitation on methods which may be adopted for property included in the election to apply this section.)
(5) Requirements of election —(i) In general. Except as otherwise provided in paragraph (d)(2) of this section dealing with expenditures for the repair, maintenance, rehabilitation or improvement of certain property, no provision of this section shall apply to any property other than eligible property to which the taxpayer elects in accordance with this section, to apply this section. For the time and manner of election, and certain conditions to an election, see paragraph (f) of this section. Except as otherwise provided in subparagraph (4)(iii) of this paragraph, subdivision (v) of this subparagraph and in subparagraph (6)(iii) of this paragraph, a taxpayer's election to apply this section may not be revoked or modified after the last day prescribed for filing the election. Thus, for example, after such day, a taxpayer may not cease to apply this section to property included in the election, establish different vintage accounts for the taxable year of election, select a different period from the asset depreciation range for any such account, or adopt a different first-year convention for any such account.
(ii) Property required to be included in election. Except as otherwise provided in subdivision (iii) of this subparagraph dealing with certain “used property”, in subdivision (iv) of this subparagraph dealing with “section 38 property”, in subdivision (v) of this subparagraph dealing with property subject to special depreciation or amortization, in subdivision (vi) of this subparagraph dealing with certain section 1250 property, in subdivision (vii) of this subparagraph dealing with certain subsidiary assets, and in paragraph (e)(3) (i) and (iv) of this section dealing with transactions to which section 381(a) applies, if the taxpayer elects to apply this section to any eligible property first placed in service by the taxpayer during the taxable year of election, the election shall apply to all such eligible property, whether placed in service in a trade or business or held for production of income.
(iii) Special 10 percent used property rule. ( a ) If ( 1 ) the unadjusted basis of eligible used section 1245 property (as defined in ( c ) of this subdivision) first placed in service by the taxpayer during the taxable year of election, for which no specific used property asset guideline class (as defined in ( c ) of this subdivision) is in effect for the taxable year, exceeds ( 2 ) 10 percent of the unadjusted basis of all eligible section 1245 property first placed in service during the taxable year of election, the taxpayer may exclude all (but not less than all) the property described in ( a )( 1 ) of this subdivision from the election to apply this section.
( b ) If ( 1 ) the unadjusted basis of eligible used section 1250 property first placed in service by the taxpayer during the taxable year of election, for which no specific used property asset guideline class is in effect for the taxable year, exceeds ( 2 ) 10 percent of the unadjusted basis of all eligible section 1250 property first placed in service during the taxable year of election, the taxpayer may exclude all (but not less than all) the property described in ( b )( 1 ) of this subdivision from the election to apply this section.
( c ) For the purposes of this section, the term “used property” means property the original use of which does not commence with the taxpayer. Solely for the purpose of determining whether the 10 percent rule of this subdivision is satisfied, ( 1 ) eligible used property first placed in service during the taxable year and excluded from the election to apply this section pursuant to subdivision (v)( a ) of this subparagraph and ( 2 ) eligible property acquired during the taxable year in a transaction to which section 381(a) applies, shall all be treated as used property regardless of whether such property would be treated as new property under section 167(c) and the regulations thereunder. The term “specific used property asset guideline class” means a class established in accordance with subparagraph (4) of this paragraph solely for used property primarily used in connection with the activity to which the class relates.
(iv) Property subject to investment tax credit. The taxpayer may exclude from an election to apply this section all, or less than all, units of eligible property first placed in service during the taxable year which is—
( a ) “Section 38 property” as defined in section 48(a) which meets the requirements of section 49 and which is not property described in section 50, or
( b ) Property to which section 47(a)(5)(B) applies which would be section 38 property but for section 49 and which is placed in service to replace section 38 property (other than property described in section 50) disposed of prior to August 15, 1971.
(v) Property subject to special method of depreciation or authorization. ( a ) In the case of eligible property first placed in service in a taxable year of election (and not otherwise properly excluded from an election to apply this section) the taxpayer may not compute depreciation for any of such property in the asset guideline class under a method not described in section 167(b) (1), (2), (3), or (k) unless he ( 1 ) computes depreciation under a method or methods not so described for eligible property first placed in service in the taxable year in the asset guideline class with an unadjusted basis at least equal to 75 percent of the unadjusted basis of all eligible property first placed in service in the taxable year in the asset guideline class and ( 2 ) agrees to continue to depreciate such property under such method or methods until the consent of the Commissioner is obtained to a change in method. The consent of the Commissioner must be obtained by filing Form 3115 with the Commissioner of Internal Revenue, Washington, D.C. 20224, within the first 180 days of the taxable year for which the change is desired. If for the taxable year of election the taxpayer computes depreciation under any method not described in section 167(b) (1), (2), (3), or (k) for any eligible property (other than property otherwise properly excluded from an election to apply this section) first placed in service during the taxable year, an election to apply this section for the taxable year shall not include such property or any other eligible property in the same asset guideline class as such property. With respect to a taxable year beginning before January 1, 1973, if the taxpayer has adopted a method of depreciation which is not permitted under this subdivision, the taxpayer may under this section adopt a method of depreciation permitted under this subdivision or otherwise comply with the provisions of this subdivision.
( b ) An election to apply this section shall not include eligible property for which, for the taxable year of election, the taxpayer computes depreciation under section 167(k), or computes amortization under section 169, 184, 185, 187, 188, or paragraph (b) of § 1.162-11. If the taxpayer has elected to apply this section to eligible property described in section 167(k), 169, 184, 185, or 187 and the taxpayer thereafter computes depreciation or amortization for such property for any taxable year in accordance with section 167(k), 169, 184, 185, or 187, then the election to apply this section to such property shall terminate as of the beginning of the taxable year for which depreciation or amortization is computed under such section. Application of this section to the property for any period prior to the termination date will not be affected by the termination. The unadjusted basis of the property shall be removed as of the termination date from the unadjusted basis of the vintage account. The depreciation reserve established for the account shall be reduced by the depreciation allowable for the property, computed in the manner prescribed in paragraph (c)(1)(v)( b ) of this section for determination of the adjusted basis of the property. See paragraph (d)(3)(vii)( e ) of this section for treatment of salvage value when property is removed from a vintage account.
(vi) Certain section 1250 property. ( a ) The taxpayer may exclude from an election to apply this section all, or less than all, items of eligible section 1250 property first placed in service during the taxable year of election provided that—
( 1 ) The item is first placed in service before the earlier of the effective date of the first supplemental asset guideline class including such property established in accordance with subparagraph (4)(ii) of this paragraph, or January 1, 1974, and
( 2 ) The taxpayer establishes that a useful life shorter than the asset guideline period in effect on January 1, 1971, for such item of property is justified for such taxable year.
( b ) If the taxpayer excludes an item of section 1250 property from an election to apply this section in accordance with this subdivision, the useful life justified under Revenue Procedure 62-21 in accordance with this subdivision for the taxable year of exclusion will be treated as justified for such item of section 1250 property for the taxable year of the exclusion and all subsequent taxable years.
(vii) Subsidiary assets. The taxpayer may exclude from an election to apply this section all (but not less than all) subsidiary assets first placed in service during the taxable year of election in an asset guideline class, provided that—
( a ) The unadjusted basis of eligible subsidiary assets first placed in service during the taxable year in the class is as much as 3 percent of the unadjusted basis of all eligible property first placed in service during the taxable year in the class, and
( b ) Such subsidiary assets are first placed in service by the taxpayer before the earlier of ( 1 ) the effective date of the first supplemental asset guideline class including such subsidiary assets established in accordance with subparagraph (4)(ii) of this paragraph, or ( 2 ) January 1, 1974.
(6) Special rule for certain public utility property —(i) Requirement of normalization in certain cases. Under section 167(1), in the case of public utility property (as defined in section 167(1)(3)(A)), if the taxpayer—
( a ) Is entitled to use a method of depreciation other than a “subsection (1) method” of depreciation (as defined in section 167(1)(3)(F)) only if it uses the “normalization method of accounting” (as defined in section 167(1)(3)(G)) with respect to such property, or
( b ) Is entitled for the taxable year to use only a “subsection (1) method” of depreciation, such property shall be eligible property (as defined in subparagraph (2) of this paragraph) only if the taxpayer normalizes the tax deferral resulting from the election to apply this section.
(ii) Normalization. The taxpayer will be considered to normalize the tax deferral resulting from the election to apply this section only if it computes its tax expense for purposes of establishing its cost of service for ratemaking purposes and for reflecting operating results in its regulated books of account using a period for depreciation no less than the lesser of—
( a ) 100 percent of the asset guideline period in effect in accordance with subparagraph (4)(ii) of this paragraph for the first taxable year to which this section applies, or
( b ) The period for computing its depreciation expense for ratemaking purposes and for reflecting operating results in its regulated books of account, and makes adjustments to a reserve to reflect the deferral of taxes resulting from the election to apply this section. A determination whether the taxpayer is considered to normalize (within the meaning of the preceding sentence) the tax deferral resulting from the election to apply this section shall be made in a manner consistent with the principles for determining whether a taxpayer is using the “normalization method of accounting” (within the meaning of section 167(1)(3)(G)). [Removed] See § 1.167(1)-1(h).
(iii) Failure to normalize. If a taxpayer, which has elected to apply this section to any eligible public utility property and is required under subdivision (i) of this subparagraph to normalize the tax deferral resulting from the election to apply this section to such property, fails to normalize such tax deferral, the election to apply this section to such property shall terminate as of the beginning of the taxable year for which the taxpayer fails to normalize such tax deferral. Application of this section to such property for any period prior to the termination date will not be affected by the termination. The unadjusted basis of the property shall be removed as of the termination date from the unadjusted basis of the vintage account. The depreciation reserve established for the account shall be reduced by the depreciation allowable for the property, computed in the manner prescribed in paragraph (c)(1)(v)( b ) of this section for determination of the adjusted basis of the property. See paragraph (d)(3)(vii)( e ) of this section for treatment of salvage value when property is removed from a vintage account.
(iv) Examples. The principles of this subparagraph may be illustrated by the following examples:
(7) Mere change in form of conducting a trade or business. Property which was first placed in service by the transferor before January 1, 1971, shall not be eligible property if such property is first placed in service by the transferee after December 31, 1970, by reason of a mere change in the form of conducting a trade or business in which such property is used. A mere change in the form of conducting a trade or business in which such property is used will be considered to have occurred if—
(i) The transferor (or in a case where the transferor is a partnership, estate, trust, or corporation, the partners, beneficiaries, or shareholders) of such property retains a substantial interest in such trade or business, or
(ii) The basis of such property in the hands of the transferee is determined in whole or in part by reference to the basis of such property in the hands of the transferor.
(c) Manner of determining allowance —(1) In general —(i) Computation of allowance. ( a ) The allowance for depreciation of property in a vintage account shall be determined in the manner specified in this paragraph by using the method of depreciation adopted by the taxpayer for the account and a rate based upon the asset depreciation period for the account. (For limitations on methods of depreciation permitted with respect to property, see section 167 (c) and (j) and subdivision (iv) of this subparagraph.) In applying the method of depreciation adopted by the taxpayer, the annual allowance for depreciation of a vintage account shall be determined without adjustment for the salvage value of the property in such account except that no account may be depreciated below the reasonable salvage value of the account. (For rules regarding estimation and treatment of salvage value, see paragraph (d)(1) and (3) (vii) and (viii) of this section.) Regardless of the method of depreciation adopted by the taxpayer, the depreciation allowable for a taxable year with respect to a vintage account may not exceed the amount by which (as of the beginning of the taxable year) the unadjusted basis of the account exceeds ( 1 ) the reserve for depreciation established for the account plus ( 2 ) the salvage value of the account. The unadjusted basis of a vintage account is defined in subdivision (v) of this subparagraph. The adjustments to the depreciation reserve are described in subdivision (ii) of this subparagraph.
( b ) The annual allowance for depreciation of a vintage account using the straight line method of depreciation shall be determined by dividing the unadjusted basis of the vintage account (without reduction for salvage value) by the number of years in the asset depreciation period selected for the account. See subdivision (iii)( b ) of this subparagraph for the manner of computing the depreciation allowance following a change from the declining balance method or the sum of the years-digits method to the straight line method.
( c ) In the case of the sum of the years-digits method, the annual allowance for depreciation of a vintage account shall be computed by multiplying the unadjusted basis of the vintage account (without reduction for salvage value) by a fraction, the numerator of which changes each year to a number which corresponds to the years remaining in the asset depreciation period for the account (including the year for which the allowance is being computed) and the denominator of which is the sum of all the year's digits corresponding to the asset depreciation period for the account. See subdivision (iii)( c ) of this subparagraph for the manner of computing the depreciation allowance following a change from the declining balance method to the sum of the years-digits method.
( d ) The annual allowance for depreciation of a vintage account using a declining balance method is determined by applying a uniform rate to the excess of the unadjusted basis of the vintage account over the depreciation reserve established for that account. The rate under the declining balance method may not exceed twice the straight line rate based upon the asset depreciation period for the vintage account.
( e ) The allowance for depreciation under this paragraph shall constitute the amount of depreciation allowable under section 167. See section 179 for additional first-year allowance for certain property.
(ii) Establishment of depreciation reserve. The taxpayer must establish a depreciation reserve for each vintage account. The amount of the reserve for a guideline class must be stated on each income tax return on which depreciation with respect to such class is determined under this section. The depreciation reserve for a vintage account consists of the accumulated depreciation allowable under this section with respect to the vintage account, increased by the adjustments for ordinary retirements prescribed by paragraph (d)(3)(iii) of this section, by the adjustments for reduction of the salvage value of a vintage account prescribed by paragraph (d)(3)(vii)( d ) of this section, and by the adjustments for transfers to supplies or scrap prescribed by paragraph (d)(3)(viii)( b ) of this section, and decreased by the adjustments for extraordinary retirements and certain special retirements as prescribed by paragraph (d)(3) (iv) and (v) of this section, by the adjustments for the amount of the reserve in excess of the unadjusted basis of a vintage account prescribed by paragraph (d)(3)(ix)( a ) of this section, and by the adjustments for property removed from a vintage account prescribed by paragraphs (b)(4)(iii)( e ), (5)(v)( b ) and (6)(iii) of this section. The adjustments to the depreciation reserve for ordinary retirements during the taxable year shall be made as of the beginning of the taxable year. The adjustments to the depreciation reserve for extraordinary retirements shall be made as of the date the retirement is treated as having occurred in accordance with the first-year convention (described in subparagraph (2) of this paragraph) adopted by the taxpayer for the vintage account. The adjustment to the depreciation reserve for reduction of salvage value and for transfers to supplies or scrap shall, in the case of an ordinary retirement, be made as of the beginning of the taxable year, and in the case of an extraordinary retirement the adjustment for reduction of salvage value shall be made as of the date the retirement is treated as having occurred in accordance with the first-year convention (described in subparagraph (2) of this paragraph) adopted by the taxpayer for the vintage account. The adjustment to the depreciation reserve for property removed from a vintage account in accordance with paragraph (b)(4)(iii)( e ), (5)(v)( b ) and (6)(iii) of this section shall be made as of the beginning of the taxable year. The depreciation reserve of a vintage account may not be decreased below zero.
(iii) Consent to change in method of depreciation. ( a ) During the asset depreciation period for a vintage account, the taxpayer is permitted to change under this section from a declining balance method of depreciation to the sum of the years-digits method of depreciation and from a declining balance method of depreciation or the sum of the years-digits method of depreciation to the straight line method of depreciation with respect to such account. Except as provided in section 167(j)(2)(1), and paragraph (e)(3)(i) of this section, no other changes in the method of depreciation adopted for a vintage account will be permitted. The provisions of § 1.167(e)-1 shall not apply to any change in depreciation method permitted under this section. The change in method applies to all property in the vintage account and must be adhered to for the entire taxable year of the change.
( b ) When a change is made to the straight line method of depreciation, the annual allowance for depreciation of the vintage account shall be determined by dividing the adjusted basis of the vintage account (without reduction for salvage value) by the number of years remaining (at the time as of which the change is made) in the asset depreciation period selected for the account. However, the depreciation allowable for any taxable year following a change to the straight line method may not exceed an amount determined by dividing the unadjusted basis of the vintage account (without reduction for salvage value) by the number of years in the asset depreciation period selected for the account.
( c ) When a change is made from the declining balance method of depreciation to the sum of the years-digits method of depreciation, the annual allowance for depreciation of a vintage account shall be determined by multiplying the adjusted basis of the account (without reduction for salvage value) at the time as of which the change is made by a fraction, the numerator of which changes each year to a number which corresponds to the number of years remaining in the asset depreciation period selected for the account (including the year for which the allowance is being computed), and the denominator of which is the sum of all the year's digits corresponding to the number of years remaining in the asset depreciation period at the time as of which the change is made.
( d ) The number of years remaining in the asset depreciation period selected for an account is equal to the asset depreciation period less the number of years of depreciation previously allowed. For this purpose, regardless of the first year convention adopted by the taxpayer, it will be assumed that depreciation was allowed for one-half of a year in the first year.
( e ) The taxpayer shall furnish a statement setting forth the vintage accounts for which the change is made with the income tax return filed for the taxable year of the change.
( f ) The principles of this subdivision may be illustrated by the following examples:
1 Rate applied to adjusted basis of the account (without reduction by salvage) at the time as of which the change is made to the straight line method.
2 The allowable depreciation is limited by estimated salvage.
1 Rate applied to $900, the amount of assets placed in service during the first half of the taxable year.
2 The allowable depreciation is limited by estimated salvage.
1 Rate is equal to one-half of 5.5/18. The denominator is equal to 5.5 + 4.5 + 3.5 + 2.5 + 1.5 + 0.5.
2 The allowable depreciation is limited by estimated salvage.
1 Rate applied to $900, the amount of assets placed in service during the first half of the taxable year.
2 The allowable depreciation is limited by estimated salvage.
1 The allowable depreciation is limited by estimated salvage.
(iv) Limitation on methods. ( a ) The same method of depreciation must be adopted for all property in a single vintage account. Generally, the method of depreciation which may be adopted is subject to the limitations contained in section 167 (c), (j) and (l).
( b ) Except as otherwise provided in section 167(j) with respect to certain eligible section 1250 property—
( 1 ) In the case of a vintage account for which the taxpayer has selected an asset depreciation period of 3 years or more and which only contains property the original use of which commences with the taxpayer, any method of depreciation described in section 167(b) (1), (2), or (3) may be adopted, but if the vintage account contains property the original use of which does not commence with the taxpayer, or if the asset depreciation period for the account is less than 3 years, a method of depreciation described in section 167(b) (2) or (3) may not be adopted for the account, and
( 2 ) The declining balance method using a rate not in excess of 150 percent of the straight line rate based upon the asset depreciation period for the vintage account may be adopted for the account even if the original use of the property does not commence with the taxpayer provided the asset depreciation period for the account is at least 3 years.
( c ) The term “original use” means the first use to which the property is put, whether or not such use corresponds to the use of such property by the taxpayer. (See § 1.167(c)-1).
(v) Unadjusted and adjusted basis. ( a ) For purposes of this section, the unadjusted basis of an asset (including an “excluded addition” and a “property improvement” as described, respectively, in paragraph (d)(2) (vi) and (vii) of this section) is its cost or other basis without any adjustment for depreciation or amortization (other than depreciation under section 179) but with other adjustments required under section 1016 or other applicable provisions of law. The unadjusted basis of a vintage account is the total of the unadjusted bases of all the assets in the account. The unadjusted basis of a “special basis vintage account” as described in paragraph (d)(3)(vi) of this section is the amount of the property improvement determined in paragraph (d)(2)(vii)( a ) of this section.
( b ) The adjusted basis of a vintage account is the amount by which the unadjusted basis of the account exceeds the reserve for depreciation for the account. The adjusted basis of an asset in a vintage account is the amount by which the unadjusted basis of the asset exceeds the amount of depreciation allowable for the asset under this section computed by using the method of depreciation and the rate applicable to the account. For purposes of this subdivision, the depreciation allowable for an asset shall include, to the extent identifiable, the amount of proceeds previously added to the depreciation reserve in accordance with paragraph (d)(3)(iii) of this section upon the retirement of any portion of such asset. (See paragraph (d)(3)(vi) of this section for election under certain circumstances to allocate adjusted basis of an amount of property improvement determined under paragraph (d)(2)(vii)( a ) of this section.)
(2) Conventions applied to additions and retirements —(i) In general. The allowance for depreciation of a vintage account (whether an item account or a multiple asset account) shall be determined by applying one of the conventions described in subdivisions (ii) and (iii) of this subparagraph. (For the manner of applying a convention in the case of taxable years beginning before and ending after December 31, 1970, see subparagraph (3) of this paragraph.) The same convention must be adopted for all vintage accounts of a taxable year, but the same convention need not be adopted for the vintage accounts of another taxable year. An election to apply this section must specify the convention adopted. (See paragraph (f) of this section for information required in making the election.) The convention adopted by the taxpayer is a method of accounting for purposes of section 446, but the consent of the Commissioner will be deemed granted to make an annual adoption of either of the conventions described in subdivisions (ii) and (iii) of this subparagraph.
(ii) Modified half-year convention. The depreciation allowance for a vintage account for which the taxpayer adopts the “modified half-year convention” shall be determined by treating: ( a ) All property in such account which is placed in service during the first half of the taxable year as placed in service on the first day of the taxable year; and ( b ) all property in such account which is placed in service during the second half of the taxable year as placed in service on the first day of the succeeding taxable year. The depreciation allowance for a vintage account for a taxable year in which there is an extraordinary retirement (as defined in paragraph (d) (3) (ii) of this section) of property first placed in service during the first half of the taxable year is determined by treating all such retirements from such account during the first half of the taxable year as occurring on the first day of the taxable year and all such retirements from such account during the second half of the taxable year as occurring on the first day of the second half of the taxable year. The depreciation allowance for a vintage account for a taxable year in which there is an extraordinary retirement (as defined in paragraph (d)(3)(ii) of this section) of property first placed in service during the second half of the taxable year is determined by treating all such retirements from such account during the first half of the taxable year as occurring on the first day of the second half of the taxable year and all such retirements in the second half of the taxable year as occurring on the first day of the succeeding taxable year.
(iii) Half-year convention. The depreciation allowance for a vintage account for which the taxpayer adopts the “half-year convention” shall be determined by treating all property in the account as placed in service on the first day of the second half of the taxable year and by treating all extraordinary retirements (as defined in paragraph (d)(3)(ii) of this section) from the account as occurring on the first day of the second half of the taxable year.
(iv) Rules of application. ( a ) The first-year convention adopted for a vintage account must be consistently applied to all additions to and all extraordinary retirements from such account. See paragraph (d)(3) (ii) and (iii) of this section for definition and treatment of ordinary retirements.
( b ) If the actual number of months in a taxable year is other than 12 full calendar months, depreciation is allowed only for such actual number of months and the term “taxable year”, for purposes of this subparagraph, shall mean only such number of months. In such event, the first half of such taxable year shall be deemed to expire at the close of the last day of a calendar month which is the closest such last day to the middle of such taxable year and the second half of such taxable year shall be deemed to begin the day after the expiration of the first half of such taxable year. If a taxable year consists of a period which includes only 1 calendar month, the first half of the taxable year shall be deemed to expire on the first day which is nearest to the midpoint of the month, and the second half of the taxable year shall begin the day after the expiration of the first half of the month.
( c ) For purposes of this subparagraph, for property placed in service after November 14, 1979, other than depreciable property described in paragraph (c)(2)(iv)( e ) of this section, the taxable year of the person placing such property in service does not include any month before the month in which the person begins engaging in a trade or business or holding depreciable property for the production of income.
( d ) For purposes of paragraph (c)(2) (iv)( c ) of this section—
( 1 ) For property placed in service after February 21, 1981, an employee is not considered engaged in a trade or business by virtue of employment.
( 2 ) If a person engages in a small amount of trade or business activity after February 21, 1981, for the purpose of obtaining a disproportionately large depreciation deduction for assets for the taxable year in which they are placed in service, and placing those assets in service represents a substantial increase in the person's level of business activity, then for purposes of depreciating those assets the person will not be treated as beginning a trade or business until the increased amount of business activity begins. For property held for the production of income, the principle of the preceding sentence applies.
( 3 ) A person may elect to apply the rules of § 1.167(a)-11 (c)(2)(iv)( d ) as set forth in T.D. 7763 (“( d ) rules in T.D. 7763”). This election shall be made by reflecting it under paragraph (f)(4) of this section in the books and records. If necessary, amended returns shall be filed.
( 4 ) If an averaging convention was adopted in reliance on or in anticipation of the ( d ) rules in T.D. 7763, that convention may be changed without regard to paragraph (f)(3) of this section. Similarly, if an election is made under paragraph (c)(2)(iv)( d )( 3 ) of this section to apply to the ( d ) rules in T.D. 7763, the averaging convention adopted for the taxable years for which the election is made may be changed. The change shall be made by filing a timely amended return for the taxable year for which the convention was adopted. Notwithstanding the three preceding sentences, if an averaging convention was adopted in reliance on or in anticipation of the ( d ) rules in T.D. 7763, and if an election is made to apply those rules, the averaging convention adopted cannot be changed except as provided in paragraph (f) of this section.
( e ) The rules in paragraph (c)(2)(iv)( c ) of this section do not apply to depreciable property placed in service after November 14, 1979, and the rules in paragraph (c)(2)(iv)( d ) of this section do not apply to depreciable property placed in service after February 21, 1981, with respect to which substantial expenditures were paid or incurred prior to November 15, 1979. For purposes of the preceding sentence, expenditures will not be considered substantial unless they exceed the lesser of 30 percent of the final cost of the property or $10 million. Expenditures that are not includible in the basis of the depreciable property will be considered expenditures with respect to property if they are directly related to a specific project involving such property. For purposes of determining whether expenditures were paid or incurred prior to November 15, 1979, expenditures made by a person (transferor) other than the person placing the property in service (transferee) will be taken into account only if the basis of the property in the hands of the transferee is determined in whole or in part by reference to the basis in the hands of the transferor. The principle of the preceding sentence also applies if there are multiple transfers.
(v) Mass assets. In the case of mass assets, if extraordinary retirements of such assets in a guideline class during the first half of the taxable year are allocated to a particular vintage year for which the taxpayer applied the modified half-year convention, then that portion of the mass assets so allocated which bears the same ratio to the total number of mass assets so allocated as the mass assets in the same vintage and assets guideline class placed in service during the first half of that vintage year bear to the total mass assets in the same vintage and asset guideline class shall be treated as retired on the first day of the taxable year. The remaining mass assets which are subject to extraordinary retirement during the first half of the taxable year and which are allocated to that vintage year and assets guideline class shall be treated as retired on the first days of the second half of the taxable year. If extraordinary retirements of mass assets in a guideline class occur in the second half of the taxable year and are allocated to a particular vintage year for which the taxpayer applied the modified half-year convention, then that portion of the mass assets so allocated which bears the same ratio to the total number of mass assets so allocated as the mass assets in the same vintage and asset guideline class first placed in service during the first half of that vintage year bear to the total mass assets in the same vintage and asset guideline class shall be treated as retired on the first day of the second half of the taxable year. The remaining mass assets which are subject to extraordinary retirements during the second half of the taxable year and which are allocated to that same vintage and asset guideline class shall be treated as retired on the first day of the succeeding taxable year. If the taxpayer has applied the half-year convention for the vintage year to which the extraordinary retirements are allocated, the mass assets shall be treated as retired on the first day of the second half of the taxable year.
(3) Taxable years beginning before and ending after December 31, 1970. In the case of a taxable year which begins before January 1, 1971, and ends after December 31, 1970, property first placed in service after December 31, 1970, but treated as first placed in service before January 1, 1971, by application of a convention described in subparagraph (2) of this paragraph shall be treated as provided in this subparagraph. The depreciation allowed (or allowable) for the taxable year shall consist of the depreciation allowed (or allowable) for the period before January 1, 1971, determined without regard to this section plus the amount allowable for the period after December 31, 1970, determined under this section. However, neither the modified half-year convention described in subparagraph (2)(ii) of this paragraph, nor the half-year convention described in subparagraph (2)(iii) of this paragraph may for any such taxable year be applied with respect to property placed in service after December 31, 1970, to allow depreciation for any period prior to January 1, 1971, unless such convention is consistent with the convention applied by the taxpayer with respect to property placed in service in such taxable year prior to January 1, 1971.
(4) Examples. The principles of this paragraph may be illustrated by the following examples:
(d) Special rules for salvage, repairs and retirements —(1) Salvage value —(i) Definition of gross salvage value. “Gross salvage” value is the amount which is estimated will be realized upon a sale or other disposition of the property in the vintage account when it is no longer useful in the taxpayer's trade or business or in the production of his income and is to be retired from service, without reduction for the cost of removal, dismantling, demolition or similar operations. If a taxpayer customarily sells or otherwise disposes of property at a time when such property is still in good operating condition, the gross salvage value of such property is the amount expected to be realized upon such sale or disposition, and under certain circumstances, as where such property is customarily sold at a time when it is still relatively new, the gross salvage value may constitute a relatively large proportion of the unadjusted basis of such property.
(ii) Definition of salvage value. “Salvage value” means gross salvage value less the amount, if any, by which the gross salvage value is reduced by application of section 167(f). Generally, as provided in section 167(f), a taxpayer may reduce the amount of gross salvage value of a vintage account by an amount which does not exceed 10 percent of the unadjusted basis of the personal property (as defined in section 167(f)(2)) in the account. See paragraph (b)(3)(ii) of this section for requirement of separate vintage accounts for personal property described in section 167(f)(2).
(iii) Estimation of salvage value. The salvage value of each vintage account of the taxable year shall be estimated by the taxpayer at the time the election to apply this section is made, upon the basis of all the facts and circumstances existing at the close of the taxable year in which the account is established. The taxpayer shall specify the amount, if any, by which gross salvage value taken into account is reduced by application of section 167(f). See paragraph (f)(2) of this section for requirement that the election specify the estimated salvage value for each vintage account of the taxable year of election. The salvage value estimated by the taxpayer will not be redetermined merely as a result of fluctuations in price levels or as a result of other facts and circumstances occurring after the close of the taxable year of election. Salvage value for a vintage account need not be established or increased as a result of a property improvement as described in subparagraph (2) (vii) of this paragraph. The taxpayer shall maintain records reasonably sufficient to determine facts and circumstances taken into account in estimating salvage value.
(iv) Salvage as limitation on depreciation. In no case may a vintage account be depreciated below a reasonable salvage value after taking into account any reduction in gross salvage value permitted by section 167(f).
(v) Limitation on adjustment of reasonable salvage value. The salvage value established by the taxpayer for a vintage account will not be redetermined if it is reasonable. Since the determination of salvage value is a matter of estimation, minimal adjustments will not be made. The salvage value established by the taxpayer will be deemed to be reasonable unless there is sufficient basis in the facts and circumstances existing at the close of the taxable year in which the account is established for a determination of an amount of salvage value for the account which exceeds the salvage value established by the taxpayer for the account by an amount greater than 10 percent of the unadjusted basis of the account at the close of the taxable year in which the account is established. If the salvage value established by the taxpayer for the account is not within the 10 percent range, or if the taxpayer follows the practice of understating his estimates of gross salvage value to take advantage of this subdivision, and if there is a determination of an amount of salvage value for the account which exceeds the salvage value established by the taxpayer for the account, an adjustment will be made by increasing the salvage value established by the taxpayer for the account by an amount equal to the difference between the salvage value as determined and the salvage value established by the taxpayer for the account. For the purposes of this subdivision, a determination of salvage value shall include all determinations at all levels of audit and appellate proceedings, and as well as all final determinations within the meaning of section 1313(a) (1). This subdivision shall apply to each such determination. (See example (3) of subdivision (vi) of this subparagraph.)
(vi) Examples. The principles of this subparagraph may be illustrated by the following examples in which it is assumed that the taxpayer has not followed a practice of understating his estimates of gross salvage value:
(2) Treatment of repairs —(i) In general. ( a ) Sections 162, 212, and 263 provide general rules for the treatment of certain expenditures for the repair, maintenance, rehabilitation or improvement of property. In general, under those sections, expenditures which substantially prolong the life of an asset, or are made to increase its value or adapt it to a different use are capital expenditures. If an expenditure is treated as a capital expenditure under section 162, 212, or 263, it is subject to the allowance for depreciation. On the other hand, in general, expenditures which do not substantially prolong the life of an asset or materially increase its value or adapt it for a substantially different use may be deducted as an expense in the taxable year in which paid or incurred. Expenditures, or a series of expenditures, may have characteristics both of deductible expenses and capital expenditures. Other expenditures may have the characteristics of capital expenditures, as in the case of an “excluded addition” (as defined in subdivision (vi) of this subparagraph). This subparagraph provides a simplified procedure for determining whether expenditures with respect to certain property are to be treated as deductible expenses or capital expenditures.
( b ) [Reserved]
(ii) Election of repair allowance. In the case of an asset guideline class which consists of “repair allowance property” as defined in subdivision (iii) of this subparagraph, subject to the provisions of subdivision (v) of this subparagraph, the taxpayer may elect to apply the asset guideline class repair allowance described in subdivision (iii) of this subparagraph for any taxable year ending after December 31, 1970, for which the taxpayer elects to apply this section.
(iii) Repair allowance for an asset guideline class. For a taxable year for which the taxpayer elects to apply this section, the “repair allowance” for an asset guideline class which consists of “repair allowance property” is an amount equal to—
( a ) The average of ( 1 ) the unadjusted basis of all “repair allowance property” in the asset guideline class at the beginning of the taxable year, less in the case of such property in a vintage account the unadjusted basis of all such property retired in an ordinary retirement (as described in subparagraph (3)(ii) of this paragraph) in prior taxable years, and ( 2 ) the unadjusted basis of all “repair allowance property” in the asset guideline class at the end of the taxable year, less in the case of such property in a vintage account the unadjusted basis of all such property retired in an ordinary retirement (including ordinary retirements during the taxable year), multiplied by—
( b ) The repair allowance percentage in effect for the asset guideline class for the taxable year.
(iv) Application of asset guideline class repair allowance. In accordance with the principles of sections 162, 212, and 263, if the taxpayer pays or incurs any expenditures during the taxable year for the repair, maintenance, rehabilitation or improvement of eligible property (determined without regard to paragraph (b)(2)(ii) of this section), the taxpayer must either—
( a ) If such property is repair allowance property and if the taxpayer elects to apply the repair allowance for the asset guideline class, treat an amount of all such expenditures in such taxable year with respect to all such property in the asset guideline class which does not exceed in total the repair allowance for that asset guideline class as deductible repairs, and treat the excess of all such expenditures with respect to all such property in the asset guideline class in the manner described for a property improvement in subdivision (viii) of this subparagraph, or
( b ) If such property is not repair allowance property or if the taxpayer does not elect to apply the repair allowance for the asset guideline class, treat each of such expenditures in such taxable year with respect to all such property in the asset guideline class as either a capital expenditure or as a deductible repair in accordance with the principles of sections 162, 212, and 263 (without regard to ( a ) of this subdivision), and treat the expenditures which are required to be capitalized under sections 162, 212, and 263 (without regard to ( a ) of this subdivision) in the manner described for a property improvement in subdivision (viii) of this subparagraph.
(v) Special rules for repair allowance. ( a ) The asset guideline class repair allowance described in subdivision (iii) of this subparagraph shall apply only to expenditures for the repair, maintenance, rehabilitation or improvement of repair allowance property (as described in subdivision (iii) of this subparagraph). The taxpayer may apply the asset guideline class repair allowance for the taxable year only if he maintains books and records reasonably sufficient to determine:
( 1 ) The amount of expenditures paid or incurred during the taxable year for the repair, maintenance, rehabilitation or improvement of repair allowance property in the asset guideline class, and
( 2 ) The expenditures (and the amount thereof) with respect to such property which are for excluded additions (such as whether the expenditure is for an additional identifiable unit of property, or substantially increases the productivity or capacity of an existing identifiable unit of property or adapts it for a substantially different use).
( b ) If for the taxable year the taxpayer elects to deduct under section 263(e) expenditures with respect to repair allowance property consisting of railroad rolling stock (other than a locomotive) in a particular asset guideline class, the taxpayer may not, for such taxable year, use the asset guideline class repair allowance described in subdivision (iii) of this subparagraph for any property in such asset guideline class.
( c )( 1 ) If the taxpayer repairs, rehabilitates or improves property for sale or resale to customers, the asset guideline class repair allowance described in subdivision (iii) of this subparagraph shall not apply to expenditures for the repair, maintenance, rehabilitation or improvement of such property, or ( 2 ) if a taxpayer follows the practice of acquiring for his own use property (in need of repair, rehabilitation or improvement to be suitable for the use intended by the taxpayer) and of making expenditures to repair, rehabilitate or improve such property in order to take advantage of this subparagraph, the asset guideline class repair allowance described in subdivision (iii) of this subparagraph shall not apply to such expenditures. In either event, such property shall not be “repair allowance property” as described in subdivision (iii) of this subparagraph.
(vi) Definition of excluded addition. The term “excluded addition” means—
( a ) An expenditure which substantially increases the productivity of an existing identifiable unit of property over its productivity when first acquired by the taxpayer;
( b ) An expenditure which substantially increases the capacity of an existing identifiable unit of property over its capacity when first acquired by the taxpayer;
( c ) An expenditure which modifies an existing identifiable unit of property for a substantially different use;
( d ) An expenditure for an identifiable unit of property if ( 1 ) such expenditure is for an additional identifiable unit of property or ( 2 ) such expenditure (other than an expenditure described in ( e ) of this subdivision) is for replacement of an identifiable unit of property which was retired;
( e ) An expenditure for replacement of a part in or a component or portion of an existing identifiable unit of property (whether or not such part, component or portion is also an identifiable unit of property) if such part, component or portion is for replacement of a part, component or portion which was retired in a retirement upon which gain or loss is recognized (or would be recognized but for a special nonrecognition provision of the Code or § 1.1502-13).
( f ) In the case of a building or other structure (in addition to ( b ), ( c ), ( d ), and ( e ) of this subdivision which also apply to such property), an expenditure for additional cubic or linear space; and
( g ) In the case of those units of property of pipelines, electric utilities, telephone companies, and telegraph companies consisting of lines, cables and poles (in addition to ( a ) through ( e ) of this subdivision which also apply to such property), an expenditure for replacement of a material portion of the unit of property.
( 1 ) Replaces the five manually operated elevators with highspeed automatic elevators at a cost of $400,000;
( 2 ) Replaces the cable in one of the existing automatic elevators at a cost of $1,700. The replacements of the elevators are excluded additions under ( d )( 2 ) of this subdivision. The replacement of the cable is not an excluded addition.
(vii) Definition of property improvement. The term “property improvement” means—
( a ) If the taxpayer treats expenditures for the asset guideline class under subdivision (iv) ( a ) of this subparagraph, the amount of all expenditures paid or incurred during the taxable year for the repair, maintenance, rehabilitation or improvement of repair allowance property in the asset guideline class, which exceeds the asset guideline class repair allowance for the taxable year; and
( b ) If the taxpayer treats expenditures for the asset guideline class under subdivision (iv) ( b ) of this subparagraph, the amount of each expenditure paid or incurred during the taxable year for the repair, maintenance, rehabilitation or improvement of property which is treated under sections 162, 212, and 263 as a capital expenditure.
(viii) Treatment of property improvements and excluded additions. If for the taxable year there is a property improvement as described in subdivision (vii) of this subparagraph or an excluded addition as described in subdivision (vi) of this subparagraph, the following rules shall apply—
( a ) The total amount of any property improvement for the asset guideline class determined under subdivision (vii)( a ) of this subparagraph shall be capitalized in a single “special basis vintage account” of the taxable year in accordance with the taxpayer's election to apply this section for the taxable year (applied without regard to paragraph (b)(5)(v)( a ) of this section). See subparagraph (3)(vi) of this paragraph for definition and treatment of a “special basis vintage account”.
( b ) Each property improvement determined under subdivision (vii)( b ) of this subparagraph, if it is eligible property, shall be capitalized in a vintage account of the taxable year in accordance with the taxpayer's election to apply this section for the taxable year (applied without regard to paragraph (b)(5)(v)( a ) of this section).
( c ) Each excluded addition, if it is eligible property, shall be capitalized in a vintage account of the taxable year in accordance with the taxpayer's election to apply this section for the taxable year.
(ix) Examples. The principles of this subparagraph may be illustrated by the following examples:
(3) Treatment of retirements —(i) In general. The rules of this subparagraph specify the treatment of all retirements from vintage accounts. The rules of § 1.167(a)-8 shall not apply to any retirement from a vintage account. An asset in a vintage account is retired when such asset is permanently withdrawn from use in a trade or business or in the production of income by the taxpayer. A retirement may occur as a result of a sale or exchange, by other act of the taxpayer amounting to a permanent disposition of an asset, or by physical abandonment of an asset. A retirement may also occur by transfer of an asset to supplies or scrap.
(ii) Definitions of ordinary and extraordinary retirements. The term “ordinary retirement” means any retirement of section 1245 property from a vintage account which is not treated as an “extraordinary retirement” under this subparagraph. The retirement of an asset from a vintage account in a taxable year is an “extraordinary retirement” if—
( a ) The asset is section 1250 property;
( b ) The asset is section 1245 property which is retired as the direct result of fire, storm, shipwreck, or other casualty and the taxpayer, at his option consistently applied (taking into account type, frequency, and the size of such casualties) treats such retirements as extraordinary; or
( c)(1 ) The asset is section 1245 property which is retired (other than by transfer to supplies or scrap) in a taxable year as the direct result of a cessation, termination, curtailment, or disposition of a business, manufacturing, or other income producing process, operation, facility or unit, and (2) the unadjusted basis (determined without regard to subdivision (vi) of this subparagraph) of all such assets so retired in such taxable year from such account as a direct result of the event described in ( c)(1 ) of this subdivision exceeds 20 percent of the unadjusted basis of such account immediately prior to such event.
( d ) The asset is section 1245 property which is retired after December 30, 1980 by a charitable contribution for which a deduction is allowable under section 170.
(iii) Treatment of ordinary retirements. No loss shall be recognized upon an ordinary retirement. Gain shall be recognized only to the extent specified in this subparagraph. All proceeds from ordinary retirements shall be added to the depreciation reserve of the vintage account from which the retirement occurs. See subdivision (vi) of this subparagraph for optional allocation of basis in the case of a special basis vintage account. See subdivision (ix) of this subparagraph for recognition of gain when the depreciation reserve exceeds the unadjusted basis of the vintage account. The amount of salvage value for a vintage account shall be reduced (but not below zero) as of the beginning of the taxable year by the excess of ( a ) the depreciation reserve for the account, after adjustment for depreciation allowable for such taxable year and all other adjustments prescribed by this section (other than the adjustment prescribed by subdivision (ix) of this subparagraph), over ( b ) the unadjusted basis of the account less the amount of salvage value for the account before such reduction. Thus, in the case of a vintage account with an unadjusted basis of $1,000 and a salvage value of $100, to the extent that proceeds from ordinary retirements increase the depreciation reserve above $900, the salvage value is reduced. If the proceeds increase the depreciation reserve for the account to $1,000, the salvage value is reduced to zero. The unadjusted basis of the asset retired in an ordinary retirement is not removed from the account and the depreciation reserve for the account is not reduced by the depreciation allowable for the retired asset. The previously unrecovered basis of the retired asset will be recovered through the allowance for depreciation with respect to the vintage account. See subdivision (v)( a ) of this subparagraph for treatment of retirements on which gain or loss is not recognized in whole or in part. See subdivision (v)( b ) of this subparagraph for treatment of retirements by disposition to a member of an affiliated group as defined in section 1504(a). See subdivision (v)( c ) of this subparagraph for treatment of transfers between members of an affiliated group of corporations or other related parties as extraordinary retirements.
(iv) Treatment of extraordinary retirements. ( a ) Unless the transaction is governed by a special nonrecognition section of the Code such as 1031 or 337 or is one to which subdivision (v)( b ) of this subparagraph applies, gain or loss shall be recognized upon an extraordinary retirement in the taxable year in which such retirement occurs subject to section 1231, section 165, and all other applicable provisions of law such as sections 1245 and 1250. If the asset which is retired in an extraordinary retirement is the only or last asset in the account, the account shall terminate and no longer be an account to which this section applies. In all other cases, the unadjusted basis of the retired asset shall be removed from the unadjusted basis of the vintage account, and the depreciation reserve established for the account shall be reduced by the depreciation allowable for the retired asset computed in the manner prescribed in paragraph (c) (1)(v)( b ) of this section for determination of the adjusted basis of the asset. See subdivision (ix) of this subparagraph for recognition of gain in the case of an account containing section 1245 property when the depreciation reserve exceeds the unadjusted basis of the vintage account. See subdivision (iii) of this subparagraph for reduction of salvage value for such an account when the depreciation reserve exceeds the unadjusted basis of the account minus salvage value. See subdivision (v)( b ) of this subparagraph for treatment of retirements by disposition to a member of an affiliated group as defined in section 1504(a).
( b ) The principles of this subdivision may be illustrated by the following examples:
(v) Special rule for certain retirements. ( a ) In the case of an ordinary retirement on which gain or loss is in whole or in part not recognized because of a special nonrecognition section of the Code, such as 1031 or 337, no part of the proceeds from such retirement shall be added to the depreciation reserve of the vintage account in accordance with subdivision (iii) of this subparagraph. Instead, such retirement shall for all purposes of this section be treated as an extraordinary retirement.
( b ) The provisions of § 1.1502-13 shall apply to a retirement. In the case of an ordinary retirement to which the provisions of § 1.1502-13 apply, no part of the proceeds from such retirement shall be added to the depreciation reserve of the vintage account in accordance with subdivision (iii) of this subparagraph. Instead, such retirement shall for all purposes of this section be treated as an extraordinary retirement.
( c ) In a case in which property is transferred, in a transaction which would without regard to this subdivision be treated as an ordinary retirement, during the taxable year in which first placed in service to a person who bears a relationship described in section 179(d)(2) (A) or (B), such transfer shall for all purposes of this section be treated as an extraordinary retirement.
( d )( 1 ) If, in the case of mass assets, it is impracticable for the taxpayer to maintain records from which he can establish the vintage of such assets as retirements occur, and if he adopts other reasonable recordkeeping practices, then the vintage of mass asset retirements may be determined by use of an appropriate mortality dispersion table. Such a mortality dispersion table may be based upon an acceptable sampling of the taxpayer's actual experience or other acceptable statistical or engineering techniques. Alternatively, the taxpayer may use a standard mortality dispersion table prescribed by the Commissioner for this purpose. If the taxpayer uses such standard mortality dispersion table for any taxable year of election, it must be used for all subsequent taxable years of election unless the taxpayer obtains the consent of the Commissioner to change to another dispersion table or to actual identification of retirements. For information requirements regarding mass assets, see paragraph (f)(5) of this section.
( 2 ) For purposes of this section, the term “mass assets” has the same meaning as when used in paragraph (e)(4) of § 1.47-1.
( e ) The principles of this subdivision may be illustrated by the following examples:
(vi) Treatment of special basis vintage accounts. A “special basis vintage account” is a vintage account for an amount of property improvement determined under subparagraph (2) (vii)( a ) of this paragraph. In general, reference in this section to a “vintage account” shall include a special basis vintage account. The unadjusted basis of a special basis vintage account shall be recovered through the allowance for depreciation in accordance with this section over the asset depreciation period for the account. Except as provided in this subdivision, the unadjusted basis, adjusted basis and reserve for depreciation of such account shall not be allocated to any specific asset in the asset guideline class, and the provisions of this subparagraph shall not apply to such account. However, in the event of a sale, exchange or other disposition of “repair allowance property” (as described in subparagraph (2)(iii) of this paragraph) in an extraordinary retirement as described in subdivision (ii) of this subparagraph (or if the asset is not in a vintage account, in an abnormal retirement as described in § 1.167(a)-8), the taxpayer may, if consistently applied to all such retirements in the taxable year and adequately identified in the taxpayer's books and records, elect to allocate the adjusted basis (as of the end of the taxable year) of all special basis vintage accounts for the asset guideline class to each such retired asset in the proportion that the adjusted basis of the retired asset (as of the beginning of the taxable year) bears to the adjusted basis of all repair allowance property in the asset guideline class at the beginning of the taxable year. The election to allocate basis in accordance with this subdivision shall be made on the tax return filed for the taxable year. The principles of this subdivision may be illustrated by the following example:
(vii) Reduction in the salvage value of a vintage account. ( a ) A taxpayer may apply this section without reducing the salvage value for a vintage account in accordance with this subdivision or in accordance with subdivision (viii) of this subparagraph (relating to transfers to supplies or scrap). See subdivision (iii) of this subparagraph for reduction of salvage value in certain circumstances in the amount of proceeds from ordinary retirements.
( b ) However, the taxpayer may, at his option, follow the consistent practice of reducing, as retirements occur, the salvage value for a vintage account by the amount of salvage value attributable to the retired asset, or the taxpayer may consistently follow the practice of so reducing the salvage value for a vintage account as extraordinary retirements occur while not reducing the salvage value for the account as ordinary retirements occur. If the taxpayer does not reduce the salvage value for a vintage account as ordinary retirements occur, the taxpayer may be entitled to a deduction in the taxable year in which the last asset is retired from the account in accordance with subdivision (ix) ( b ) of this subparagraph.
( c ) For purposes of this subdivision, the portion of the salvage value for a vintage account attributable to a retired asset may be determined by multiplying the salvage value for the account by a fraction, the numerator of which is the unadjusted basis of the retired asset and the denominator of which is the unadjusted basis of the account, or any other method consistently applied which reasonably reflects that portion of the salvage value for the account originally attributable to the retired asset.
( d ) In the case of ordinary retirements the taxpayer may—
( 1 ) In the case of retirements (other than by transfer to supplies or scrap) follow the consistent practice of reducing the salvage value for the account by the amount of salvage value attributable to the retired asset and not adding the same amount to the depreciation reserve for the account, and
( 2 ) In the case of retirements by transfer to supplies or scrap, follow the consistent practice of reducing the salvage value for the account by the amount of salvage value attributable to the retired asset and not adding the same amount to the depreciation reserve for the account (in which case the basis in the supplies or scrap account of the retired asset will be zero) or follow the consistent practice of reducing the salvage value for the account by the amount of salvage value attributable to the retired asset and adding the same amount to the depreciation reserve for the account (up to an amount which does not increase the depreciation reserve to an amount in excess of the unadjusted basis of the account) in which case the basis in the supplies or scrap account of the retired asset will be the amount added to the depreciation reserve for the account.
( e ) In the event of a removal of property from a vintage account in accordance with paragraph (b)(4)(iii)( e ), (5)(v)( b ) or (6)(iii) of this section the salvage value for the account may be reduced by the amount of salvage value attributable to the asset removed determined as provided in ( c ) of this subdivision.
(viii) Special optional adjustments for transfers to supplies or scrap. If the taxpayer does not follow the consistent practice of reducing, as ordinary retirements occur, the salvage value for a vintage account in accordance with subdivision (vii) of this subparagraph, the taxpayer may (in lieu of the method described in subdivision (vii) ( c ) and ( d ) of this subparagraph) follow the consistent practice of reducing salvage value as ordinary retirements occur by transfer of assets to supplies or scrap and of determining the basis (in the supplies or scrap account) as assets retired in an ordinary retirement by transfer to supplies or scrap, in the following manner—
( a ) The taxpayer may determine the value of the asset (not to exceed its unadjusted basis) by any reasonable method consistently applied (such as average cost, conditioned cost, or fair market value) if such method is adequately identified in the taxpayer's books and records.
( b ) The value attributable to the asset determined in accordance with ( a ) of this subdivision shall be subtracted from the salvage value for the account (to the extent thereof) and the greater of ( 1 ) the amount subtracted from the salvage value for the vintage account and ( 2 ) the value of the asset determined in accordance with ( a ) of this subdivision, shall be added to the reserve for depreciation of this vintage account.
( c ) The amount added to the reserve for depreciation of the vintage account in accordance with ( b ) of this subdivision shall be treated as the basis of the retired asset in the supplies or scrap account.
(ix) Recognition of gain or loss in certain situations. ( a ) In the case of a vintage account for section 1245 property, if at the end of any taxable year after adjustment for depreciation allowable for such taxable year and all other adjustments prescribed by this section, the depreciation reserve established for such account exceeds the unadjusted basis of the account, the entire amount of such excess shall be recognized as gain in such taxable year. Such gain—
( 1 ) Shall constitute gain to which section 1245 applies to the extent that it does not exceed the total amount of depreciation allowances in the depreciation reserve at the end of such taxable year, reduced by gain recognized pursuant to this subdivision with respect to the account previously treated as gain to which section 1245 applies, and
( 2 ) May constitute gain to which section 1231 applies to the extent that it exceeds such total amount as so reduced.
( b ) In the case of an account for section 1245 property, if at the time the last asset in the vintage account is retired the unadjusted basis of the account exceeds the depreciation reserve for the account (after all adjustments prescribed by this section), the entire amount of such excess shall be recognized in such taxable year as a loss under section 165 or as a deduction for depreciation under section 167. If the retirement of such asset occurs by sale or exchange on which gain or loss is recognized, the amount of such excess may constitute a loss subject to section 1231. Upon retirement of the last asset in a vintage account, the account shall terminate and no longer be an account to which this section applies. See subdivision (xi) of this subparagraph for treatment of certain multiple asset and item accounts.
( c ) The principles of this subdivision may be illustrated by the following example:
(x) Dismantling cost. The cost of dismantling, demolishing, or removing an asset in the process of a retirement from the vintage account shall be treated as an expense deductible in the year paid or incurred, and such cost shall not be subtracted from the depreciation reserve for the account.
(xi) Special rule for treatment of multiple asset and item accounts. For the purposes of subdivision (ix)( b ) of this subparagraph, all accounts (other than a special basis vintage account as described in subdivision (vi) of this subparagraph) of the same vintage in the same asset guideline class for which the taxpayer has selected the same asset depreciation period and adopted the same method of depreciation, and which contain only section 1245 property permitted by paragraph (b)(3)(ii) of this section to be included in the same vintage account, shall be treated as a single multiple asset vintage account.
(4) Examples. The principles of this paragraph may be illustrated by the following examples:
( b ) In the fifth year of the asset depreciation period, three assets are sold in an ordinary retirement for $300. Under paragraph (c)(1)(ii) of this section and subparagraph (3)(iii) of this paragraph, the proceeds of the retirement are added to the depreciation reserve as of the beginning of the fifth year. Accordingly, the reserve as of the beginning of the fifth year is $700, that is, $400 of depreciation as of the beginning of the year plus $300 proceeds from ordinary retirements. The depreciation allowance for the fifth year is $100, that is 1/10 multiplied by the unadjusted basis of $1,000, without reduction for salvage. Accordingly, the depreciation reserve at the end of the fifth year is $800.
( c ) In the sixth year, asset X is sold in an extraordinary retirement for $30 and gain or loss is recognized. Under the first-year convention used by the taxpayer, the unadjusted basis of X, $300, is removed from the unadjusted basis of the vintage account as of the beginning of the sixth year and the depreciation reserve as of the beginning of such year is reduced to $650 by removing the depreciation applicable to asset X, $150 (see subparagraph (3)(iv) of this paragraph). Since the depreciation reserve ($650) exceeds the unadjusted basis of the account ($700) minus salvage value ($100) by $50, under subparagraph (3)(iii) of this paragraph, salvage value is reduced by $50. No depreciation is allowable for the sixth year.
( d ) In the seventh year, an asset is sold in an ordinary retirement for $110. This would increase the reserve as of the beginning of the seventh year to $760 and under subparagraph (3)(iii) of this paragraph the salvage value is reduced to zero. Under subparagraph (3)(ix)( a ) of this paragraph the depreciation reserve is then decreased to $700 (the unadjusted basis of the account) and $60 is reported as gain, without regard to the adjusted basis of the asset. No depreciation is allowable for the seventh year since the depreciation reserve ($700) equals the unadjusted basis of the account ($700).
( e )( 1 ) In the eighth year, A elects to apply this section and to treat expenditures during the year for repair, maintenance, rehabilitation or improvement under subparagraph (2)(iii) and (iv)( a ) of this paragraph (the “guideline class repair allowance”). This results in the treatment of $300 as a property improvement for the asset guideline class. (See subparagraph (2)(vii) of this paragraph for definition of a property improvement.) The property improvement is capitalized in a special basis vintage account of the eighth taxable year (see subparagraph (2)(viii)( a ) of this paragraph). A selects an asset depreciation period of 10 years and adopts the straight line method for the special basis vintage account. A adopts the modified half-year convention for the eighth year.
( 2 ) In the eighth year, A sells asset Y in an ordinary retirement for $175. Under paragraph (c)(1)(ii) of this section and subparagraph (3)(iii) of this paragraph, $175 is added to the depreciation reserve for the account as of the beginning of the taxable year. Since the depreciation reserve for the account ($875) exceeds the unadjusted basis of the account ($700) by $175, that amount of gain is recognized under subparagraph (3)(ix) of this paragraph. Upon recognition of gain in the amount of $175, the depreciation reserve for the account is reduced to $700.
( 3 ) No depreciation is allowable in the eighth year for the vintage account since the depreciation reserve ($700) equals the unadjusted basis of the account ($700). The depreciation allowable in the eighth year for the special basis vintage account is $15, that is, unadjusted basis of $300, multiplied by 1/10 , the asset depreciation period selected for the special basis vintage account, but limited to $15 under the modified half-year convention. (See paragraph (e)(1)(iv) of this section for treatment of $150 of the property improvement as first placed in service in the first half of the taxable year and $150 of the property improvement as first placed in service in the last half of the taxable year.)
(e) Accounting for eligible property —(1) Definition of first placed in service —(i) In general. The term “first placed in service” refers to the time the property is first placed in service by the taxpayer, not to the first time the property is placed in service. Property is first placed in service when first placed in a condition or state of readiness and availability for a specifically assigned function, whether in a trade or business, in the production of income, in a tax-exempt activity, or in a personal activity. In general, the provisions of paragraph (d)(1)(ii) and (d)(2) of § 1.46-3 shall apply for the purpose of determining the date on which property is placed in service, but see subdivision (ii) of this subparagraph for special rule for certain replacement parts. In the case of a building which is intended to house machinery and equipment and which is constructed, reconstructed, or erected by or for the taxpayer and for the taxpayer's use, the building will ordinarily be placed in service on the date such construction, reconstruction, or erection is substantially complete and the building is in a condition or state of readiness and availability. Thus, for example, in the case of a factory building, such readiness and availability shall be determined without regard to whether the machinery or equipment which the building houses, or is intended to house, has been placed in service. However, in an appropriate case, as for example where the building is essentially an item of machinery or equipment, or the use of the building is so closely related to the use of the machinery or equipment that it clearly can be expected to be replaced or retired when the property it initially houses is replaced or retired, the determination of readiness or availability of the building shall be made by taking into account the readiness and availability of such machinery or equipment. The date on which depreciation begins under a convention used by the taxpayer or under a particular method of depreciation, such as the unit of production method or the retirement method, shall not determine the date on which the property is first placed in service. See paragraph (c)(2) of this section for application of a first-year convention to determine the allowance for depreciation of property in a vintage account.
(ii) Certain replacement parts. Property (such as replacement parts) the cost or other basis of which is deducted as a repair expense in accordance with the asset guideline repair allowance described in paragraph (d)(2)(iii) of this section shall not be treated as placed in service.
(iii) Property improvements and excluded additions. ( a ) Except as provided in ( b ) of this subdivision, a property improvement determined under paragraph (d)(2)(vii)( b ) of this section, and an excluded addition (other than an excluded addition referred to in the succeeding sentence) is first placed in service when its cost is paid or incurred. The general rule in subdivision (i) of this subparagraph applies to an excluded addition described in paragraph (d) (2)(vi) ( d ), ( e ), ( f ), or ( g ) of this section.
( b ) If a property improvement or an excluded addition to which the first sentence of ( a ) of this subdivision applies is paid or incurred in part in one taxable year and in part in the succeeding taxable year (or in part in the first half of a taxable year and in part in the last half of the taxable year) the taxpayer may at his option consistently treat such property improvements and excluded additions under the general rule in subdivision (i) of this subparagraph.
(iv) Certain property improvements. In the case of an amount of property improvement determined under paragraph (d)(2)(vii)( a ) of this section, one-half of such amount is first placed in service in the first half of the taxable year in which the cost is paid or incurred and one-half is first placed in service in the last half of such taxable year.
(v) Special rules for clearing accounts. In the case of public utilities which consistently account for certain property through “clearing accounts,” the date on which such property is first placed in service shall be determined in accordance with rules to be prescribed by the Commissioner.
(2) Special rules for transferred property. If eligible property is first placed in service by the taxpayer during a taxable year of election, and the property is disposed of before the end of the taxable year, the election for such taxable year shall include such property unless such property is excluded in accordance with paragraph (b)(5) (iii), (iv, (v), (vi), or (vii) of this section.
(3) Special rules in the case of certain transfers —(i) Transaction to which section 381(a) applies. ( a ) In general the acquiring corporation in a transaction to which section 381(a) applies is for the purposes of this section treated as if it were the distributor or transferor corporation.
( b ) If the distributor or transferor corporation (including any distributor or transferor corporation of any distributor or transferor corporation) has made an election to apply this section to eligible property transferred in a transaction to which section 381(a) applies, the acquiring corporation must segregate such eligible property (to which the distributor or transferor corporation elected to apply this section) into vintage accounts as nearly coextensive as possible with the vintage accounts created by the distributor or transferor corporation identified by reference to the year the property was first placed in service by the distributor or transferor corporation. The asset depreciation period for the vintage account in the hands of the distributor or transferor corporation must be used by the acquiring corporation. The method of depreciation adopted by the distributor or transferor corporation, shall be used by the acquiring corporation unless such corporation obtains the consent of the Commissioner to use another method of depreciation in accordance with paragraph (e) of § 1.446-1 or changes the method of depreciation under paragraph (c)(1)(iii) of this section.
( c ) The acquiring corporation may apply this section to the property so acquired only if the distributor or transferor corporation elected to apply this section to such property.
( d ) See paragraph (b)(7) of this section for special rule for certain property where there is a mere change in the form of conducting a trade or business.
(ii) Partnerships, trusts, estates, donees, and corporations. Except as provided in subdivision (i) of this subparagraph with respect to transactions to which section 381(a) applies and subdivision (iv) of this subparagraph with respect to certain transfers between members of an affiliated group of corporations or other related parties, if eligible property is placed in service by an individual, trust, estate, partnership or corporation, the election to apply this section shall be made by the individual, trust, estate, partnership or corporation placing such property in service. For example, if a partnership places in service property contributed to the partnership by a partner, the partnership may elect to apply this section to such property. If the partnership does not make the election, this section will not apply to such property. See paragraph (b)(7) of this section for special rule for certain property where there is mere change in the form of conducting a trade or business.
(iii) Leased property. The asset depreciation range and the asset depreciation period for eligible property subject to a lease shall be determined without regard to the period for which such property is leased, including any extensions or renewals of such period. See paragraph (b)(5)(v) of this section for exclusion of property amortized under paragraph (b) of § 1.162-11 from an election to apply this section. In the case of a lessor of property, unless there is an asset guideline class in effect for lessors of such property, the asset guideline class for such property shall be determined as if the property were owned by the lessee. However, in the case of an asset guideline class based upon the type of property (such as trucks or railroad cars) as distinguished from the activity in which used, the property shall be classified without regard to the activity of the lessee. Notwithstanding the preceding sentence, if a lease with respect to property, which would be includible in an asset guideline class based upon the type of property under the preceding sentence (such as trucks or railroad cars), is entered into after March 12, 1971, and before April 23, 1973, or a written contract to execute such a lease is entered into during such period and such contract is binding on April 23, 1973, and at all times thereafter, and if the rent or rate of return is based on a classification of such property as if it were owned by the lessee, then such property shall be classified as if it were owned by the lessee. However, the preceding sentence shall not apply if pursuant to the terms or conditions of the lease or binding contract the rent or rate of return may be adjusted to take account of a change in the period for depreciation with respect to the property resulting from inclusion of the property in an asset guideline class based upon the type of property rather than in an asset guideline class based upon the activity of the lessee. Similarly, where the terms of such a lease or contract provide that the obligation of the taxpayer to enter into the lease is subject to a condition that the property be included in an asset guideline class based upon the activity of the lessee, the contract or lease will not be considered as binding upon the taxpayer, for purposes of this subdivision. See paragraph (b)(4)(iii)( b ) of this section for general rule for classification of property according to primary use.
(iv) Treatment of certain transfers between members of affiliated groups or other related persons. If section 38 property in an asset guideline class (determined without regard to whether the taxpayer elects to apply this section) is transferred by the taxpayer to a person who bears a relationship described in section 179(d)(2) (A) or (B), such property is in the same asset guideline class in the hands of transferee, and the transfer is neither described in section 381(a) nor treated as a disposition or cessation within the meaning of section 47, then the asset guideline period for such property selected by the taxpayer under this section shall not be shorter than the period used for computing the qualified investment with respect to the property under section 46(c). In a case in which the asset depreciation range for the asset guideline class which includes such property does not include the period for depreciation used by the transferor in computing the qualified investment with respect to such property, the transferee will not be permitted to include such property in an election under this section. However, in such a case, the transferor of the property may recompute the qualified investment for the year the property was placed in service using a period for depreciation which falls within the asset depreciation range.
(f) Election with respect to eligible property —(1) Time and manner of election —(i) In general. An election to apply this section to eligible property shall be made with the income tax return filed for the taxable year in which the property is first placed in service (see paragraph (e)(1) of this section) by the taxpayer. In the case of an affiliated group of corporations (as defined in section 1504(a)) which makes a consolidated return with respect to income tax in accordance with section 1502 and the regulations thereunder, each corporation which joins in the making of such return may elect to apply this section for a taxable year. An election to compute the allowance for depreciation under this section is a method of accounting but the consent of the Commissioner will be deemed granted to make an annual election. For election by a partnership see section 703 (b) and paragraph (e)(3)(ii) of this section. If the taxpayer does not file a timely return (taking into account extensions of the time for filing) for the taxable year in which the property is first placed in service, the election shall be filed at the time the taxpayer files his first return for that year. The election may be made with an amended return filed within the time prescribed by law (including extensions) for filing the original return for the taxable year of election. If an election is not made within the time and in the manner prescribed in this paragraph, no election may be made for such taxable year (by the filing of an amended return or in any other manner) with respect to any eligible property placed in service in the taxable year.
(ii) Other elections under this section. All other elections under this section may be made only within the time and in the manner prescribed by subdivision (i) of this subparagraph with respect to an election to apply this section.
(iii) Effective date. See paragraph (f)(6) of this section for the effective date of this paragraph.
(2) Information required. A taxpayer who elects to apply this section must specify in the election:
(i) That the taxpayer makes such election and consents to and agrees to apply, all the provisions of this section;
(ii) The asset guideline class for each vintage account of the taxable year;
(iii) The first-year convention adopted by the taxpayer for the taxable year of election;
(iv) Whether the special 10 percent used property rule described in paragraph (b)(5)(iii) of this section has been applied to exclude used property from the election;
(v) Whether the taxpayer elects to apply the asset guideline class repair allowance described in paragraph (d)(2)(iii) of this section;
(vi) Whether the taxpayer elects for the taxable year to allocate the adjusted basis of a special basis vintage account in accordance with paragraph (d)(3)(vi) of this section;
(vii) Whether any eligible property for which the taxpayer was not required or permitted to make an election was excluded because of the special rules of paragraph (b)(5)(v) or (6), or paragraph (e)(3)(i) or (iv) of this section;
(viii) Whether any “section 38 property” was excluded under paragraph (b)(5)(iv) of this section from the election to apply this section;
(ix) If the taxpayer is an electric or gas utility, whether the taxpayer elects to apply this section on the basis of a composite asset guideline class in accordance with paragraph (b)(4)(iii)( a ) of this section; and
(x) Such other information as may reasonably be required.
(3) Irrevocable election. An election to apply this section to eligible property for any taxable year may not be revoked or changed after the time for filing the election prescribed under subparagraph (1) of this paragraph has expired. No other election under this section may be revoked or changed after such time unless expressly provided for under this section. (See paragraph (b)(5)(v)( b ) of this section for special rule.)
(4) Special conditions to election to apply this section —(i) Maintenance of books and records. The taxpayer may not elect to apply this section for a taxable year unless the taxpayer maintains the books and records required under this section. In addition to any other information required under this section, the taxpayer's books and records must specify—
( a ) The asset depreciation period selected by the taxpayer for each vintage account;
( b ) If the taxpayer applies the modified half-year convention, the total cost or other basis of all eligible property first placed in service in the first half of the taxable year and the total cost or other basis of all eligible property first placed in service in the last half of the taxable year;
( c ) The unadjusted basis and salvage value for each vintage account, and the amount, if any, by which gross salvage value was decreased under section 167 (f);
( d ) Each asset guideline class for which the taxpayer elects to apply the asset guideline class repair allowance described in paragraph (d)(2)(iii) of this section;
( e ) The amount of property improvement, determined under paragraph (d)(2)(vii)( a ) of this section, for each asset guideline class for which the taxpayer elects to apply the asset guideline class repair allowance;
( f ) A reasonable description of property excluded from an election to apply this section and the basis for the exclusion;
( g ) The total unadjusted basis of all assets retired during the taxable year from each asset guideline class, and the proceeds realized during the taxable year from such retirements; and
( h ) The vintage (that is, the taxable year in which established) of the assets retired during the year from each asset guideline class.
(ii) Response to survey. Taxpayers who elect to apply this section must respond to infrequent data surveys conducted by the Treasury Department. These periodic surveys, which will be conducted on the basis of scientifically sound sampling methods, are designed to obtain data (including industry asset acquisitions and retirements) used to keep the asset guideline classes and periods up to date.
(iii) Effect of noncompliance. An election to apply this section will not be rendered invalid under this subparagraph so long as there is substantial compliance, in good faith, with the requirements of this subparagraph.
(5) Mass assets. In the case of mass assets, if the taxpayer assigns retirements to vintage accounts in the manner provided in paragraph (d)(3)(v)( c ) of this section, the following information must be supplied with form 4832:
(i) Whether the taxpayer used the standard mortality dispersion curve or a curve based upon his own experience, and
(ii) Such other reasonable information as may be required by the Commissioner.
(6) Effective date. The rules in this paragraph apply to elections for taxable years ending on or after December 31, 1978. In the case of an election for a taxable year ending before December 31, 1978, the rules in paragraph (f) of this section, in effect before the amendments made by T.D. 7593 approved January 11, 1979, shall apply. See 26 CFR § 1.167(a)-11(f) (1977) for paragraph (f) of this section as it appeared before the amendments made by T.D. 7593.
(g) Relationship to other provisions —(1) Useful life —(i) In general. Except as provided in subdivision (ii) of this subparagraph, an election to apply this section to eligible property constitutes an agreement under section 167(d) and this section to treat the asset depreciation period for each vintage account as the useful life of the property in such account for all purposes of the Code, including sections 46, 47, 48, 57, 163(d), 167(c), 167(f)(2), 179, 312(m), 514(a), and 4940(c). For example, since section 167(c) requires a useful life of at least 3 years and the asset depreciation period selected is treated as the useful life for purposes of section 167(c), the taxpayer may adopt a method of depreciation described in section 167(b) (2) or (3) for an account only if the asset depreciation period selected for the account is at least 3 years.
(ii) Special rules. ( a ) For the purposes of paragraph (d) of this section, the anticipated period of use (estimated at the close of the taxable year in which the asset is first placed in service) on the basis of which salvage value is estimated, shall be determined without regard to the asset depreciation period for the property.
( b ) For the purposes of sections 162 and 263 and the regulations thereunder, whether an expenditure prolongs the life of an asset shall be determined on the basis of the anticipated period of use of the asset (estimated at the close of the taxable year in which the asset is first placed in service) without regard to the asset depreciation period for such asset.
( c ) The determination whether a transaction with respect to qualified property constitutes a sale or a lease of such property shall be made without regard to the asset depreciation period for the property.
( d ) The principles of this subdivision may be illustrated by the following example:
(2) Section 167(d) agreements. If the taxpayer has, prior to January 1, 1971, entered into a section 167(d) agreement which applies to any eligible property, the taxpayer will be permitted to withdraw the eligible property from the agreement provided that an election is made to apply this section to such property. The statement of intent to withdraw eligible property from such an agreement must be made in an election filed for the taxable year in which the property is first placed in service. The withdrawal, in accordance with this subparagraph, of any eligible property from a section 167(d) agreement shall not affect any other property covered by such an agreement.
(3) Relationship to the straight line method —(i) In general. For purposes of determining the amount of depreciation which would be allowable under the straight line method of depreciation, such amount shall be computed with respect to any property in a vintage account using the straight line method in the manner described in paragraph (c)(1)(i) of this section and a rate based upon the period for the vintage account selected from the asset depreciation range. Thus, for example, section 57(a)(3) requires a taxpayer to compute an amount using the straight line method of depreciation if the taxpayer uses an accelerated method of depreciation. For purposes of section 57(a)(3), the amount for property in a vintage account shall be computed using the asset depreciation period for the vintage account selected from the asset depreciation range. In the case of property to which the taxpayer does not elect to apply this section, such amount computed by using the straight line method shall be determined under § 1.167(b)-1 without regard to this section.
(ii) Examples. The principles of this subparagraph may be illustrated by the following example:
( b ) Assume that the provisions of section 57(a)(3) apply to the property. The amount of the tax preference would be $22,200, that is, the excess of the depreciation allowed under this section ($44,400) over the depreciation which would have been allowable if the taxpayer had used the period selected from the asset depreciation range and the straight line rate ($22,200).
§ 1.167(a)-12   Depreciation based on class lives for property first placed in service before January 1, 1971.
(a) In general —(1) Summary. This section provides an elective class life system for determining the reasonable allowance for depreciation of certain classes of assets for taxable years ending after December 31, 1970. The system applies only to assets placed in service before January 1, 1971. Depreciation for such assets during periods prior to January 1, 1971, may have been determined in accordance with Revenue Procedure 62-21. Accordingly, rules are provided which permit taxpayers to apply the system in taxable years ending after December 31, 1970, to such assets without the necessity of changing or regrouping their depreciation accounts other than as previously required by Revenue Procedure 62-21. The system is designed to minimize disputes between taxpayers and the Internal Revenue Service as to the useful life of assets, salvage value, and repairs. See § 1.167(a)-11 for a similar system for property placed in service after December 31, 1970. See paragraph (d)(2) of § 1.167(a)-11 for treatment of expenditures for the repair, maintenance, rehabilitation or improvement of certain property. The system provided by this section is optional with the taxpayer. An election under this section applies only to qualified property in an asset guideline class for which an election is made and only for the taxable year of election. The taxpayer's election is made with the income tax return for the taxable year. This section also revokes the reserve ratio test for taxable years ending after December 31, 1970, and provides transitional rules for taxpayers who after January 11, 1971, adopt Revenue Procedure 62-21 for a taxable year ending prior to January 1, 1971.
(2) Revocation of reserve ratio test and other matters. Except as otherwise expressly provided in this section and in paragraph (b)(5)(vi) of § 1.167(a)-11, the provisions of Revenue Procedure 62-21 shall not apply to any property for any taxable year ending after December 31, 1970, whether or not the taxpayer elects to apply this section to any property. See paragraph (f) of this section for rules for the adoption of Revenue Procedure 62-21 for taxable years ending prior to January 1, 1971.
(3) Definition of qualified property. The term “qualified property” means tangible property which is subject to the allowance for depreciation provided by section 167(a), but only if—
(i) An asset guideline class and asset guideline period are in effect for such property for the taxable year, and
(ii) The property is first placed in service by the taxpayer before January 1, 1971,
(iii) The property is placed in service before January 1, 1971, but first placed in service by the taxpayer after December 31, 1970, and is not includible in an election under § 1.167(a)-11 by reason of § 1.167(a)-11(b)(7) (property acquired as a result of a mere change in form) or § 1.167(a)-11(e)(3)(i) (certain property acquired in a transaction to which section 381(a) applies), or
(iv) The property is acquired and first placed in service by the taxpayer after December 31, 1970, pursuant to a binding written contract entered into prior to January 1, 1971, and is excluded in accordance with paragraph (b)(5)(iv) of § 1.167(a)-11 from an election to apply § 1.167(a)-11.
(4) Requirements of election —(i) In general. An election to apply this section to qualified property must be made within the time and in the manner specified in paragraph (e) of this section. The election must specify that the taxpayer consents to and agrees to apply all the provisions of this section. The election may be made separately for each asset guideline class. Thus, a taxpayer may for the taxable year elect to apply this section to one, more than one, or all asset guideline classes in which he has qualified property. An election to apply this section for a taxable year must include all qualified property in the asset guideline class for which the election is made.
(ii) Special rules for exclusion of property from application of this section. ( a ) If for the taxable year of election, the taxpayer computes depreciation under section 167(k) or computes amortization under sections 169, 185, 187, 188, or paragraph (b) of § 1.162-11 with respect to property, such property is not qualified property for such taxable year. If for the taxable year of election, the taxpayer computes depreciation under any method of depreciation (other than a method described in the preceding sentence) not permitted by subparagraph (5)(v) of this paragraph for any property in an asset guideline class (other than subsidiary assets excluded from an election under ( b ) of this subdivision), no property in such asset guideline class is qualified property for such taxable year.
( b ) The taxpayer may exclude from an election to apply this section all (but not less than all) subsidiary assets. Subsidiary assets so excluded are not qualified property for such taxable year. For purposes of this subdivision the term “subsidiary assets” includes jigs, dies, molds, returnable containers, glassware, silverware, textile mill cam assemblies, and other equipment includable in Group One, Class 5, of Revenue Procedure 62-21 which is usually and properly accounted for separately from other property and under a method of depreciation not expressed in terms of years.
(iii) Special rule for certain public utility property. ( a ) In the case of public utility property described in section 167(1)(3)(A)(iii) for which no guideline life was prescribed in Revenue Procedure 62-21 (or for which reference was made in Revenue Procedure 62-21 to lives or rates established by governmental regulatory agencies) of a taxpayer which—
( 1 ) Is entitled to use a method of depreciation other than a “subsection (1) method” of depreciation (as defined in section 167(1)(3)(F)) only if it uses the “normalization method of accounting” (as defined in section 167(1)(3)(G)) with respect to such property, or
( 2 ) Is entitled for the taxable year to use only a “subsection (1) method” of depreciation, such property shall be qualified property (as defined in subparagraph (3) of this paragraph) only if the taxpayer normalizes the tax deferral resulting from the election to apply this section.
( b ) The taxpayer will be considered to normalize the tax deferral resulting from the election to apply this section only if it computes its tax expense for purposes of establishing its cost of service for ratemaking purposes and for reflecting operating results in its regulated books of account using a period for depreciation no less than the period used for computing its depreciation expense for ratemaking purposes and for reflecting operating results in its regulated books of account for the taxable year, and the taxpayer makes adjustments to a reserve to reflect the deferral of taxes resulting from the use of a period for depreciation under section 167 in accordance with an election to apply this section different from the period used for computing its depreciation expense for ratemaking purposes and for reflecting operating results in its regulated books of account for the taxable year. A determination whether the taxpayer is considered to normalize under this subdivision the tax deferral resulting from the election to apply this section shall be made in a manner consistent with the principles for determining whether a taxpayer is using the “normalization method of accounting” (within the meaning of section 167(1)(3)(G)). See § 1.167(l)-1(h).
( c ) If a taxpayer, which has elected to apply this section to any qualified public utility property and is required under ( a ) of this subdivision to normalize the tax deferral resulting from the election to apply this section to such property, fails to normalize such tax deferral, the election to apply this section to such property shall terminate as of the beginning of the taxable year for which the taxpayer fails to normalize such tax deferral. Application of this section to such property for any period prior to the termination date will not be affected by this termination.
(5) Determination of reasonable allowance for depreciation —(i) In general. The allowance for depreciation of qualified property to which the taxpayer elects to apply this section shall be determined in accordance with this section. The annual allowance for depreciation is determined by using the method of depreciation adopted by the taxpayer and a rate based upon a life permitted by this section. In the case of the straight-line method of depreciation, the rate of depreciation shall be based upon the class life (or individual life if the taxpayer assigns individual depreciable lives in accordance with subdivision (iii) of this subparagraph) used by the taxpayer with respect to the assets in the asset guideline class. Such rate will be applied to the unadjusted basis of the asset guideline class (individual assets or depreciation accounts if the taxpayer assigns individual depreciable lives). In the case of the sum of the years-digits method of depreciation, the rate of depreciation will be determined based upon the remaining life of the class (or individual remaining lives if the taxpayer assigns such lives in accordance with subdivision (iii) of this subparagraph) and is applied to the adjusted basis of the class (or individual accounts or assets) as of the beginning of the taxable year of election. The remaining life of a depreciation account is determined by dividing the unrecovered cost or other basis of the account, as computed by straight-line depreciation, by the gross cost or unadjusted basis of the account, and multiplying the result by the class life used with respect to the account. In the case of the declining balance method of depreciation, the rate of depreciation for the asset guideline class shall be based upon the class life (or individual life if the taxpayer assigns such lives in accordance with subdivision (iii) of this subparagraph). Such rate is applied to the adjusted basis of the class (or individual accounts or assets) as of the beginning of the taxable year of election.
(ii) Reasonable allowance by reference to class lives. The amount of depreciation for all qualified property in an asset guideline class to which the taxpayer elects to apply this section will constitute the reasonable allowance provided by section 167(a) and the depreciation for the asset guideline class will not be adjusted if—
( a ) The taxpayer's qualified property is accounted for in one or more depreciation accounts which conform to the asset guideline class, and the depreciation for each such account is determined by using a rate based upon a life not less than the class life, or
( b ) The taxpayer's qualified property is accounted for in one or more depreciation accounts (whether or not conforming to the asset guideline class) for which depreciation is determined at a rate based upon the taxpayer's estimate of the lives of the assets (instead of the class life) and the total amount of depreciation so determined for the asset guideline class for the taxable year of election is not more than would be permitted under ( a ) of this subdivision for such year using the method of depreciation adopted by the taxpayer for the property.
(iii) Consistency when individual lives are used. If the taxpayer assigns individual depreciable lives to assets in accordance with subdivision (ii)( b ) of this subparagraph, even though the total amount of depreciation for the asset guideline class will not be adjusted, the lives assigned to the various assets in the asset guideline class must be reasonably in proportion to their relative expected periods of use in the taxpayer's business. Thus, although the taxpayer who uses individual asset lives normally has latitude in thereby allocating the depreciation for the asset guideline class among the assets, if the lives are grossly disproportionate (as where a short life is assigned to one asset and a long life to another even though the expected periods of use are the same), the taxpayer's allocation of depreciation to particular assets or depreciation accounts may be adjusted. For example, the taxpayer's allocation may be adjusted for purposes of determining adjusted basis under section 1016(a) or in allocating depreciation to the 50-percent limitation on percentage depletion provided by section 613(a). See paragraph (d) of this section for rules regarding the use of individual asset lives for purposes of classifying retirements as normal or abnormal.
(iv) Regrouping depreciation accounts. Without the consent of the Commissioner, the taxpayer may for any taxable year for which he elects to apply this section to an asset guideline class, regroup his accounts for that and all succeeding taxable years to conform to the asset guideline class. Other changes in accounting, including a change from item accounts to multiple-asset accounting, may be made with the consent of the Commissioner. No depreciation accounts for which the straight line or sum of the years-digits method of depreciation is adopted may be combined under this section which would not be permitted to be combined under part III of Revenue Procedure 65-13, as in effect on January 1, 1971. Accordingly, whether or not the taxpayer adopted the guideline system of Revenue Procedure 62-21 for a taxable year to which part III of Revenue Procedure 65-13 is applicable, the depreciation allowance for any taxable year of election under this section may not exceed that amount which would have been allowed for such year if the taxpayer had used item accounts or year of acquisition accounts. Thus, for example, if a calendar year taxpayer acquired a $90 asset on the first day of each year from 1966 through 1970, placed such assets in a single multiple asset account, adopted the sum of the years-digits method of depreciation and used a 5-year depreciable life for such assets, and in 1971 uses the 5-year class life determined under paragraph (b) of this section, the depreciation allowance for such assets in 1971 under this section may not exceed $60, that is, the amount which would be allowed if the taxpayer had used year of acquisition accounts for the assets for the years 1966 through 1970.
(v) Method of depreciation. The same method of depreciation must be applied to all property in a single depreciation account. The method of depreciation is subject to the limitations of section 167 (c), (j), and (l). Except as otherwise provided in this subdivision, the taxpayer must apply a method of depreciation described in section 167(b) (1), (2), or (3) for qualified property to which the taxpayer elects to apply this section. A method of depreciation permitted under section 167(b)(4) may be used under this section if the method was used by the taxpayer with respect to the property for his last taxable year ending before January 1, 1971, the method is expressed in terms of years, the taxpayer establishes to the satisfaction of the Commissioner that the method is both a reasonable and consistent method, and if the taxpayer applies paragraph (b)(2) of this section (relating to class lives in special situations) to determine a class life, that the method of determining such class life is consistent with the principles of Revenue Procedure 62-21 as applied to such a method. If the taxpayer has applied a method of depreciation with respect to the property which is not described in section 167(b) (1), (2), (3), or (4) (as permitted under the preceding sentence), he must change under this section to a method of depreciation described in section 167(b) (1), (2), or (3) for the first taxable year for which an election is made under this section. Other changes in depreciation method may be made with the consent of the Commissioner (see sec. 446 and the regulations thereunder). (See also sec. 167(e).)
(vi) Salvage value. In applying the method of depreciation adopted by the taxpayer, the annual allowance for depreciation is determined without adjustment for the salvage value of the property, except that no depreciation account may be depreciated below a reasonable salvage value for the account. See paragraph (c) of this section for definition and treatment of salvage value.
(vii) Reasonable allowance when depreciation exceeds amount based on class life. In the event that the total amount of depreciation claimed by the taxpayer on his income tax return, in a claim for refund, or otherwise, for an asset guideline class with respect to which an election is made under this section for the taxable year, exceeds the maximum amount permitted under subdivision (ii)( a ) of this subparagraph—
( a ) If the excess is established to the satisfaction of the Commissioner to be the result of a good faith mistake by the taxpayer in determining the maximum amount permitted under subdivision (ii) ( a ) of this subparagraph, the taxpayer's election to apply this section will be treated as valid and only such excess will be disallowed, and
( b ) In all other cases, the taxpayer's election to apply this section to the asset guideline class for the taxable year is invalid and the reasonable allowance for depreciation will be determined without regard to this section. (See § 1.167(a)-1 (b) for rules regarding the estimated useful life of property.)
(b) Determination of class lives —(1) Class lives in general. The class life determined under this paragraph (without regard to any range or variance permitted with respect to class lives under § 1.167(a)-11) will be applied for purposes of determining whether the allowance for depreciation for qualified property included in an election under this section is subject to adjustment. The taxpayer is not required to use the class life determined under this paragraph for purposes of determining the allowance for depreciation. Except as provided in subparagraph (2) of this paragraph, the class life of qualified property to which the taxpayer elects to apply this section is the shorter of—
(i) The asset guideline period for the asset guideline class as set forth in Revenue Procedure 72-10 as in effect on March 1, 1972 (applied without regard to any special provision therein with respect to property predominantly used outside the United States), or
(ii) The asset guideline period for the asset guideline class as set forth in any supplement or revision of Revenue Procedure 72-10, but only if and to the extent by express reference in such supplement or revision made applicable for the purpose of changing the asset guideline period or classification of qualified property to which this section applies.
(ii) The class lives for asset guideline classes 20.4 and 22.1 are their respective asset guideline periods of 12 years and 9 years in Revenue Procedure 72-10.
(iii) Accordingly, in the election for the taxable year, in accordance with paragraph (e)(3)(iii) of this section, corporation X specifies a class life of 12 years for asset guideline class 20.4 and a class life of 9 years for asset guideline class 22.1.
(2) Class lives in special situations. Notwithstanding subparagraph (1) of this paragraph, for the purposes of this section the class life for the asset guideline class determined under this subparagraph shall be used if such class life is shorter than the class life determined under subparagraph (1) of this paragraph. If property described in paragraph (a)(2)(iii) of this section in an asset guideline class is acquired by the taxpayer in a transaction to which section 381(a) applies, for purposes of this subparagraph such property shall be segregated from other property in the class and treated as in a separate asset guideline class, and the class life for that asset guideline class under this subparagraph shall be the shortest class life the transferor was entitled to use under this section for such property on the date of such transfer. In all other cases, the class life for the asset guideline class for purposes of this subparagraph shall be the shortest class life (within the meaning of sec. 4, part II, of Revenue Procedure 62-21) which can be justified by application of secs. 3.02(a), 3.03(a), or 3.05, part II, of Revenue Procedure 62-21 (other than the portion of such sec. 3.05 dealing with justification of a class life by reference to facts and circumstances) for the taxpayer's last taxable year ending prior to January 1, 1971.
(3) Classification of property —(i) In general. Property to which this section applies shall be included in the asset guideline class for the activity in which the property is primarily used in the taxable year of election. See paragraph (d)(5) of this section for rule regarding the classification of leased property.
(ii) Insubstantial activity. The provisions of Revenue Produce 62-21 with respect to classification of assets used in an activity which is insubstantial may be applied under this section.
(iii) Special rule for certain public utilities. An electric or gas utility which in accordance with Revenue Procedure 64-21 used a composite guideline class basis for applying Revenue Procedure 62-21 for its last taxable year prior to January 1, 1971, may apply Revenue Procedure 72-10 and this section on the basis of such composite asset guideline class determined as provided in Revenue Procedure 64-21. For the purposes of this section all property in the composite guideline class shall be treated as included in a single asset guideline class.
(c) Salvage value —(1) In general —(i) Definition of gross salvage value. “Gross salvage” value is the amount (determined at or as of the time of acquisition but without regard to the application of Revenue Procedure 62-21) which is estimated will be realized upon a sale or other disposition of qualified property when it is no longer useful in the taxpayer's trade or business or in the production of his income and is to be retired from service, without reduction for the cost of removal, dismantling, demolition, or similar operations. “Net salvage” is gross salvage reduced by the cost of removal, dismantling, demolition, or similar operations. If a taxpayer customarily sells or otherwise disposes of property at a time when such property is still in good operating condition, the gross salvage value of such property is the amount expected to be realized upon such sale or disposition, and under certain circumstances, as where such property is customarily sold at a time when it is still relatively new, the gross salvage value may constitute a relatively large proportion of the unadjusted basis of such property.
(ii) Definition of salvage value. “Salvage value” for purposes of this section means gross or net salvage value less the amount, if any, by which reduced by application of section 167(f). Generally, as provided in section 167(f), a taxpayer may reduce the gross or net salvage value for an account by an amount which does not exceed 10 percent of the unadjusted basis of the personal property (as defined in section 167(f)(2)) in the account.
(2) Estimation of salvage value —(i) In general. For the first taxable year for which he elects to apply this section, the taxpayer must (in accordance with paragraph (e)(3)(iv)( c ) of this section) establish salvage value for all qualified property to which the election applies. The taxpayer may (in accordance with subparagraph (1) of this paragraph) determine either gross or net salvage, but an election under this section does not constitute permission to change the manner of estimating salvage. Permission to change the manner of estimating salvage must be obtained by filing form 3115 with the Commissioner of Internal Revenue, Washington, D.C. 20224, within the time otherwise permitted for the taxable year or before September 6, 1973. Salvage value in succeeding taxable years of election will be determined by adjustments of such initial salvage value for the account, as retirements occur. This salvage value established by the taxpayer for the first taxable year of election will not be redetermined merely as a result of fluctuations in price levels or as a result of other circumstances occurring after the close of such taxable year. See paragraph (e)(3)(iv) of this section for requirements that the taxpayer specify in his election the aggregate amount of salvage value for an asset guideline class and that the taxpayer maintain records reasonably sufficient to identify the salvage value established for each depreciation account in the class.
(ii) Salvage as limitation on depreciation. In no case may an account be depreciated under this section below a reasonable salvage value, after taking into account any reduction in gross or net salvage value permitted by section 167(f). For example, if the salvage value of an account for 1971 is $75, the unadjusted basis of the account is $500, and the depreciation reserve is $425, no depreciation is allowable for 1971.
(iii) Special rule for first taxable year. If for a taxable year ending prior to January 1, 1971, the taxpayer had adopted Revenue Procedure 62-21 prior to January 12, 1971 (see paragraph (f)(2) of this section), no adjustment in the amount of depreciation allowable for any taxable year ending prior to January 1, 1971, shall be made solely by reason of establishing salvage value under this paragraph for any taxable year ending after December 31, 1970. The principles of this subdivision may be illustrated by the following example:
(3) Limitation on adjustment of reasonable salvage value. The salvage value established by the taxpayer for a depreciation account will not be redetermined if it is reasonable. Since the determination of salvage value is a matter of estimation, minimal adjustments will not be made. The salvage value established by the taxpayer will be deemed to be reasonable unless there is sufficient basis for a determination of an amount of salvage value for the account which exceeds the salvage value established by the taxpayer for the account by an amount greater than 10 percent of the unadjusted basis of the account at the close of such taxable year. If the salvage value established by the taxpayer for the account is not within the 10-percent range or if the taxpayer follows the practice of understating his estimates of salvage to take advantage of this subdivision, and if there is a determination of an amount of salvage value for the account for the taxable year which exceeds the salvage value established by the taxpayer for the account for such taxable year, an adjustment will be made by increasing the salvage value established by the taxpayer for the account by an amount equal to the difference between the salvage value as determined and the salvage value established by the taxpayer for the account. For the purposes of this subdivision, a determination of salvage value shall include all determinations at all levels of audit and appellate proceedings, and as well as all final determinations within the meaning of section 1313(a)(1). This subparagraph shall apply to each such determination.
(4) Examples. The principles of this paragraph may be illustrated by the following examples in which it is assumed that the taxpayer has established salvage value in accordance with this paragraph and has not followed a practice of understating his estimates of salvage value:
(d) Accounting for qualified property —(1) In general. Qualified property for which the taxpayer elects to apply this section may be accounted for in any number of item or multiple asset accounts.
(2) Retirements of qualified property —(i) In general. The provisions of this subparagraph and § 1.167(a)-8 apply to retirements of qualified property to which the taxpayer elects to apply this section for the taxable year. See subdivision (iii) of this subparagraph for special rule for normal retirements.
(ii) Adjusted basis of assets retired. In the case of a taxpayer who depreciates qualified property in a multiple-asset account conforming to the asset guideline class at a rate based on the class life in accordance with paragraph (a)(5)(ii)( a ) of this section, § 1.167(a)-8(c) (relating to basis of assets retired) shall be applied by assuming that the class life is the average expected useful life of the assets in the account. See § 1.167(a)-8, generally, for the basis of assets retired.
(iii) Definition of normal retirements. Notwithstanding § 1.167(a)-8(b), the determination whether a retirement of qualified property is normal or abnormal shall be made in light of all the facts and circumstances, primarily with reference to the expected period of use of the asset in the taxpayer's business without regard to paragraph (a)(5)(ii) of this section. A retirement is not abnormal unless the taxpayer can show that the withdrawal of the asset was not due to a cause which would customarily be contemplated (in light of the taxpayer's practice and experience) in setting a depreciation rate for the assets without regard to paragraph (a)(5)(ii) of this section. Thus, for example, a retirement is normal if made within the range of years which would customarily be taken into account in setting such depreciation rate and if the asset has reached a condition at which, in the normal course of events, the taxpayer customarily retires similar assets from use in his business. A retirement may be abnormal if the asset is withdrawn at an earlier time or under other circumstances, as, for example, when the asset has been damaged by casualty or has lost its usefulness suddenly as the result of extraordinary obsolescence.
(3) Special rules —(i) In general. The provisions of this subparagraph shall apply to qualified property in a taxable year for which an election to apply this section is made.
(ii) Repairs. For the purpose of sections 162 and 263 and the regulations thereunder, whether an expenditure prolongs the life of an asset shall be determined by reference to the expected period of use of the asset in the taxpayer's business without regard to paragraph (a)(5)(ii) of this section.
(iii) Sale and lease. For the purpose of comparison with the term of a lease of such property, the remaining life of qualified property shall be determined by reference to the expected period of use of the asset in the taxpayer's business without regard to paragraph (a)(5)(ii) of this section.
(4) Expected period of use. For the purposes of subparagraphs (2) and (3) of this paragraph, the determination of the expected period of use of an asset shall be made in light of all the facts and circumstances. The expected period of use of a particular asset will not necessarily coincide with the class life used for depreciation (or with the individual asset life for depreciation under the alternative method in paragraph (a)(5)(ii) ( b ) of this section for applying the class life). Thus, for example, if the question is whether an asset has been leased for a period less than, equal to or greater than its remaining life, the determination shall be based on the remaining expected period of use of the individual asset without regard to the fact that the asset is depreciated at a rate based on the class life in accordance with paragraph (a)(5)(ii)( a ) of this section.
(5) Leased property. In the case of a lessor of qualified property, unless there is an asset guideline class in effect for such lessors, the asset guideline class for such property shall be determined by reference to the activity in which such property is primarily used by the lessee. See paragraph (b)(3) of this section for general rule for classification of qualified property according to primary use. However, in the case of an asset guideline class based upon the type of property (such as trucks or railroad cars), as distinguished from the activity in which used, the property shall be classified without regard to the activity of the lessee.
(e) Election under this section —(1) Consent to change in method of accounting. An election to apply this section for a taxable year ending after December 31, 1970, is a method of accounting but the consent of the Commissioner will be deemed granted to make an annual election.
(2) Election for taxable years ending after December 31, 1976. For taxable years ending after December 31, 1976, the election to apply this section for a taxable year shall be made by attaching to the income tax return a statement that an election under this section is being made. If the taxpayer does not file a timely return (taking into account extensions of time for filing) for the taxable year, the election shall be made at the time the taxpayer files his first return for the taxable year. The election may be made with an amended return only if such amended return is filed no later than the time prescribed by law (including extensions thereof) for filing the return for the taxable year. A taxpayer who makes an election under this subparagraph must maintain books and records reflecting the information described in paragraph (e)(3) (ii) and (iii) of this section.
(3) Election for taxable years ending on or before December 31, 1976. (i) For taxable years ending on or before December 31, 1976, the election to apply this section for a taxable year may be made by filing Form 5006 with the income tax return for the taxable year. If the taxpayer does not file a timely return (taking into account extensions of time for filing) for the taxable year, the election shall be filed at the time the taxpayer files his first return for the taxable year. The election may be made with an amended return only if such amended return is filed no later than the later of ( a ) the time prescribed by law (including extensions thereof) for filing the return for the taxable year, or ( b ) November 5, 1973.
(ii) The election to apply this section for a taxable year ending on or before December 31, 1976, will be deemed to be made if the tax return (filed within the periods referred to in paragraph (e)(3)(i) of this section) contains information sufficient to establish the following:
( a ) Each asset guideline class for which the election is intended to apply;
( b ) The class life for each such asset guideline class and whether the class life is determined under paragraph (b)(1) or (2) of this section;
( c ) For each asset guideline class, as of the end of the taxable year of election, ( 1 ) the total unadjusted basis of all qualified property, ( 2 ) the aggregate of the reserves for depreciation of all accounts in the asset guideline class, and ( 3 ) the aggregate of the salvage value established for all accounts in the asset guideline class; and
( d ) Whether the taxpayer is an electric or gas utility using a composite asset guideline class basis in accordance with paragraph (b)(3)(iii) of this section.
(iii) A taxpayer to whom the election applies shall maintain books and records for each asset guideline class reasonably sufficient to identify the unadjusted basis, reserve for depreciation and salvage value established for each depreciation account in such asset guidelines class.
(f) Depreciation for taxable years ending before January 1, 1971 —(1) Adoption of Revenue Procedure 62-21 —(i) In general. Except as provided in subdivision (ii) of this subparagraph, a taxpayer may elect to be examined under the provisions of Revenue Procedure 62-21 for a taxable year ending before January 1, 1971, only in accordance with the rules of this paragraph. The election must specify:
( a ) That the taxpayer makes such election and consents to, and agrees to apply, all the provisions of this paragraph;
( b ) Each guideline class and taxable year for which the taxpayer elects to be examined under Revenue Procedure 62-21;
( c ) The class life claimed for each such guideline class;
( d ) The class life and the total amount of the depreciation for the guideline class claimed on the last income tax return for such taxable year filed prior to January 12, 1971 (or in case no income tax return was filed prior to January 12, 1971, on the first income tax return filed for such taxable year);
( e ) The class life claimed and the total amount of depreciation for the guideline class under the election to apply Revenue Procedure 62-21, in accordance with this paragraph, for the taxable year; and
( f ) If the class life or total amount of depreciation for the guideline class is different in ( d ) and ( e ) of this subdivision, a reasonable description of the computation of the class life in ( e ) of this subdivision, the amount of difference in tax liability resulting therefrom, and the amount of any refund or reduction in any deficiency in tax. The election shall be made in an amended tax return or claim for refund (or by a supplement to the tax return or claim) for the taxable year, and if the class life or total amount of depreciation for the guideline class is different in accordance with ( f ) of this subdivision, such difference shall be reflected in the amended tax return or claim for refund. Forms may be provided for making the election and submission of the information. In the case of an election made after issuance of such forms and more than 30 days after publication of notice thereof in the Internal Revenue Bulletin, the election may be made and the information submitted only in accordance with such forms. An election will not otherwise be invalid under this paragraph so long as there is substantial compliance, in good faith, with the requirements of this paragraph.
(ii) Special rule. The provisions of this subparagraph shall not apply to a guideline class in any taxable year for which the taxpayer has prior to January 12, 1971, adopted Revenue Procedure 62-21 for such class. See subparagraph (2) of this paragraph for determination of adoption of Revenue Procedure 62-21 prior to January 12, 1971.
(iii) Justification of class life claimed and limitations on refunds. If the taxpayer elects for a taxable year to be examined under the provisions of Revenue Procedure 62-21 in accordance with subdivision (i) of this subparagraph, any of the provisions of Revenue Procedure 62-21 may be applied to justify a class life claimed on the income tax return filed for such year or to offset an increase in tax liability for such year. Unless it meets the reserve ratio test, no class life will be accepted on audit which (after all other adjustments in tax liability for such year) results in a reduction (or further reduction) in the amount of tax liability shown on the income tax return (specified in subdivision (i)( d ) of this subparagraph) for such taxable year, or results in an amount of loss carryback or carryover to any taxable year, but if it is justified under Revenue Procedure 62-21 and meets the reserve ratio test, a class life will be accepted on audit without regard to the foregoing limitations and, for example, may produce a refund or credit against tax. For example, if a class life of 9 years is otherwise justified under Revenue Procedure 62-21 for 1969, but the taxpayer does not meet the reserve ratio test for 1969 using a test life of 9 years, a class life of 9 years (or any class life justified under Revenue Procedure 62-21) will be accepted on audit under Revenue Procedure 62-21 pursuant to an election in accordance with this paragraph provided it does not result in the reduction or further reduction in tax liability or in an amount of loss carryback or carryover as described in the preceding sentence. On the other hand, for example, if a class life of 10 years is justified under Revenue Procedure 62-21 for 1969 and the taxpayer meets the reserve ratio test for 1969 using a test life of 10 years, a class life of 10 years will be accepted on audit under Revenue Procedure 62-21 pursuant to an election in accordance with this paragraph even though it results in a reduction or further reduction in tax liability or in an amount of loss carryback or carryover as described above and produces a refund of tax. For purposes of this section, the term “audit” includes examination of claims for refund or credit against tax.
(iv) Definitions. For purposes of this paragraph, the determination whether the reserve ratio test is met shall be made in accordance with that portion of paragraph (b)(2) of this section which is by express reference therein made applicable to this paragraph. In addition, the guideline form of the reserve ratio test, as described in Revenue Procedure 65-13, may be applied. For purposes of this paragraph, references to Revenue Procedure 62-21 include all modifications, amendments, and supplements thereto as of January 11, 1971. The terms “class life” and “guideline class” have the same meaning as in Revenue Procedure 62-21.
(2) Determination whether Revenue Procedure 62-21 adopted prior to January 12, 1971 —(i) In general. For the purposes of this paragraph, a taxpayer will be treated as having adopted prior to January 12, 1971, Revenue Procedure 62-21 for a guideline class for a taxable year ending before January 1, 1971, only if—
( a ) For the guideline class and taxable year, the taxpayer adopted Revenue Procedure 62-21 by expressly so indicating on the income tax return filed for such taxable year prior to January 12, 1971;
( b ) For the guideline class and taxable year, the taxpayer adopted Revenue Procedure 62-21 prior to January 12, 1971, by expressly so indicating in a proceeding before the Internal Revenue Service (such as upon examination of the income tax return for such taxable year) and there is reasonable evidence to that effect; or
( c ) There is other reasonable evidence that prior to January 12, 1971, the taxpayer adopted Revenue Procedure 62-21 for the guideline class and taxable year.
(ii) Examples. The principles of this subparagraph may be illustrated by the following examples:
§ 1.167(a)-13T   Certain elections for intangible property (temporary).
For rules applying the elections under section 13261(g) (2) and (3) of the Omnibus Budget Reconciliation Act of 1993 to intangible property described in section 167(f), see § 1.197-1T.
§ 1.167(a)-14   Treatment of certain intangible property excluded from section 197.
(a) Overview. This section provides rules for the amortization of certain intangibles that are excluded from section 197 (relating to the amortization of goodwill and certain other intangibles). These excluded intangibles are specifically described in § 1.197-2(c) (4), (6), (7), (11), and (13) and include certain computer software and certain other separately acquired rights, such as rights to receive tangible property or services, patents and copyrights, certain mortgage servicing rights, and rights of fixed duration or amount. Intangibles for which an amortization amount is determined under section 167(f) and intangibles otherwise excluded from section 197 are amortizable only if they qualify as property subject to the allowance for depreciation under section 167(a).
(b) Computer software —(1) In general. The amount of the deduction for computer software described in section 167(f)(1) and § 1.197-2(c)(4) is determined by amortizing the cost or other basis of the computer software using the straight line method described in § 1.167(b)-1 (except that its salvage value is treated as zero) and an amortization period of 36 months beginning on the first day of the month that the computer software is placed in service. Before determining the amortization deduction allowable under this paragraph (b), the cost or other basis of computer software that is section 179 property, as defined in section 179(d)(1)(A)(ii), must be reduced for any portion of the basis the taxpayer properly elects to treat as an expense under section 179. In addition, the cost or other basis of computer software that is qualified property under section 168(k)(2) and § 1.168(k)-1 or § 1.168(k)-2, as applicable, 50-percent bonus depreciation property under section 168(k)(4) or § 1.168(k)-1 or § , or qualified New York Liberty Zone property under section 1400L(b) or § 1.1400L(b)-1, must be reduced by the amount of the additional first year depreciation deduction allowed or allowable, whichever is greater, under section 168(k) or section 1400L(b) for the computer software. If costs for developing computer software that the taxpayer properly elects to defer under section 174(b) result in the development of property subject to the allowance for depreciation under section 167, the rules of this paragraph (b) will apply to the unrecovered costs. In addition, this paragraph (b) applies to the cost of separately acquired computer software if the cost to acquire the software is separately stated and the cost is required to be capitalized under section 263(a).
(2) Exceptions. Paragraph (b)(1) of this section does not apply to the cost of computer software properly and consistently taken into account under § 1.162-11. The cost of acquiring an interest in computer software that is included, without being separately stated, in the cost of the hardware or other tangible property is treated as part of the cost of the hardware or other tangible property that is capitalized and depreciated under other applicable sections of the Internal Revenue Code.
(3) Additional rules. Rules similar to those in § 1.197-2 (f)(1)(iii), (f)(1)(iv), and (f)(2) (relating to the computation of amortization deductions and the treatment of contingent amounts) apply for purposes of this paragraph (b).
(c) Certain interests or rights not acquired as part of a purchase of a trade or business —(1) Certain rights to receive tangible property or services. The amount of the deduction for a right (other than a right acquired as part of a purchase of a trade or business) to receive tangible property or services under a contract or from a governmental unit (as specified in section 167(f)(2) and § 1.197-2(c)(6)) is determined as follows:
(i) Amortization of fixed amounts. The basis of a right to receive a fixed amount of tangible property or services is amortized for each taxable year by multiplying the basis of the right by a fraction, the numerator of which is the amount of tangible property or services received during the taxable year and the denominator of which is the total amount of tangible property or services received or to be received under the terms of the contract or governmental grant. For example, if a taxpayer acquires a favorable contract right to receive a fixed amount of raw materials during an unspecified period, the taxpayer must amortize the cost of acquiring the contract right by multiplying the total cost by a fraction, the numerator of which is the amount of raw materials received under the contract during the taxable year and the denominator of which is the total amount of raw materials received or to be received under the contract.
(ii) Amortization of unspecified amount over fixed period. The cost or other basis of a right to receive an unspecified amount of tangible property or services over a fixed period is amortized ratably over the period of the right. (See paragraph (c)(3) of this section regarding renewals).
(iii) Amortization in other cases. [Reserved]
(2) Rights of fixed duration or amount. The amount of the deduction for a right (other than a right acquired as part of a purchase of a trade or business) of fixed duration or amount received under a contract or granted by a governmental unit (specified in section 167(f)(2) and § 1.197-2(c)(13)) and not covered by paragraph (c)(1) of this section is determined as follows:
(i) Rights to a fixed amount. The basis of a right to a fixed amount is amortized for each taxable year by multiplying the basis by a fraction, the numerator of which is the amount received during the taxable year and the denominator of which is the total amount received or to be received under the terms of the contract or governmental grant.
(ii) Rights to an unspecified amount over fixed duration of less than 15 years. The basis of a right to an unspecified amount over a fixed duration of less than 15 years is amortized ratably over the period of the right.
(3) Application of renewals. (i) For purposes of paragraphs (c) (1) and (2) of this section, the duration of a right under a contract (or granted by a governmental unit) includes any renewal period if, based on all of the facts and circumstances in existence at any time during the taxable year in which the right is acquired, the facts clearly indicate a reasonable expectancy of renewal.
(ii) The mere fact that a taxpayer will have the opportunity to renew a contract right or other right on the same terms as are available to others, in a competitive auction or similar process that is designed to reflect fair market value and in which the taxpayer is not contractually advantaged, will generally not be taken into account in determining the duration of such right provided that the bidding produces a fair market value price comparable to the price that would be obtained if the rights were purchased immediately after renewal from a person (other than the person granting the renewal) in an arm's-length transaction.
(iii) The cost of a renewal not included in the terms of the contract or governmental grant is treated as the acquisition of a separate intangible asset.
(4) Patents and copyrights. If the purchase price of an interest (other than an interest acquired as part of a purchase of a trade or business) in a patent or copyright described in section 167(f)(2) and § 1.197-2(c)(7) is payable on at least an annual basis as either a fixed amount per use or a fixed percentage of the revenue derived from the use of the patent or copyright, the depreciation deduction for a taxable year is equal to the amount of the purchase price paid or incurred during the year. Otherwise, the basis of such patent or copyright (or an interest therein) is depreciated either ratably over its remaining useful life or under section 167(g) (income forecast method). If a patent or copyright becomes valueless in any year before its legal expiration, the adjusted basis may be deducted in that year.
(5) Additional rules. The period of amortization under paragraphs (c) (1) through (4) of this section begins when the intangible is placed in service, and rules similar to those in § 1.197-2(f)(2) apply for purposes of this paragraph (c).
(d) Mortgage servicing rights —(1) In general. The amount of the deduction for mortgage servicing rights described in section 167(f)(3) and § 1.197-2(c)(11) is determined by using the straight line method described in § 1.167(b)-1 (except that the salvage value is treated as zero) and an amortization period of 108 months beginning on the first day of the month that the rights are placed in service. Mortgage servicing rights are not depreciable to the extent the rights are stripped coupons under section 1286.
(2) Treatment of rights acquired as a pool —(i) In general. Except as provided in paragraph (d)(2)(ii) of this section, all mortgage servicing rights acquired in the same transaction or in a series of related transactions are treated as a single asset (the pool) for purposes of determining the depreciation deduction under this paragraph (d) and any gain or loss from the sale, exchange, or other disposition of the rights. Thus, if some (but not all) of the rights in a pool become worthless as a result of prepayments, no loss is recognized by reason of the prepayment and the adjusted basis of the pool is not affected by the unrecognized loss. Similarly, any amount realized from the sale or exchange of some (but not all) of the mortgage servicing rights is included in income and the adjusted basis of the pool is not affected by the realization.
(ii) Multiple accounts. If the taxpayer establishes multiple accounts within a pool at the time of its acquisition, gain or loss is recognized on the sale or exchange of all mortgage servicing rights within any such account.
(3) Additional rules. Rules similar to those in § 1.197-2(f)(1)(iii), (f)(1)(iv), and (f)(2) (relating to the computation of amortization deductions and the treatment of contingent amounts) apply for purposes of this paragraph (d).
(e) Effective dates —(1) In general. This section applies to property acquired after January 25, 2000, except that § 1.167(a)-14(c)(2) (depreciation of the cost of certain separately acquired rights) and so much of § 1.167(a)-14(c)(3) as relates to § 1.167(a)-14(c)(2) apply to property acquired after August 10, 1993 (or July 25, 1991, if a valid retroactive election has been made under § 1.197-1T).
(2) Change in method of accounting. See § 1.197-2(l)(4) for rules relating to changes in method of accounting for property to which § 1.167(a)-14 applies. However, see § 1.168(k)-1(g)(4) or 1.1400L(b)-1(g)(4) for rules relating to changes in method of accounting for computer software to which the third sentence in § 1.167(a)-14(b)(1) applies.
(3) Qualified property, 50-percent bonus depreciation property, qualified New York Liberty Zone property, or section 179 property. This section also applies to computer software that is qualified property under section 168(k)(2) or qualified New York Liberty Zone property under section 1400L(b) acquired by a taxpayer after September 10, 2001, and to computer software that is 50-percent bonus depreciation property under section 168(k)(4) acquired by a taxpayer after May 5, 2003. This section also applies to computer software that is section 179 property placed in service by a taxpayer in a taxable year beginning after 2002. The language “or § 1.168(k)-2, as applicable,” in the third sentence in paragraph (b)(1) of this section applies to computer software that is qualified property under section 168(k)(2) and placed in service by a taxpayer during or after the taxpayer's taxable year that includes September 24, 2019. However, a taxpayer may choose to apply the language “or § 1.168(k)-2, as applicable,” in the third sentence in paragraph (b)(1) of this section for computer software that is qualified property under section 168(k)(2) and acquired and placed in service after September 27, 2017, by the taxpayer during taxable years ending on or after September 28, 2017. A taxpayer may rely on the language “or § 1.168(k)-2, as applicable,” in the third sentence in paragraph (b)(1) of this section in regulation project REG-104397-18 (2018-41 I.R.B. 558) (see § 601.601(d)(2)(ii)(b) of this chapter) for computer software that is qualified property under section 168(k)(2) and acquired and placed in service after September 27, 2017, by the taxpayer during taxable years ending on or after September 28, 2017, and ending before the taxpayer's taxable year that includes September 24, 2019.

§ 1.167(b)-0   Methods of computing depreciation.
(a) In general. Any reasonable and consistently applied method of computing depreciation may be used or continued in use under section 167. Regardless of the method used in computing depreciation, deductions for depreciation shall not exceed such amounts as may be necessary to recover the unrecovered cost or other basis less salvage during the remaining useful life of the property. The reasonableness of any claim for depreciation shall be determined upon the basis of conditions known to exist at the end of the period for which the return is made. It is the responsibility of the taxpayer to establish the reasonableness of the deduction for depreciation claimed. Generally, depreciation deductions so claimed will be changed only where there is a clear and convincing basis for a change.
(b) Certain methods. Methods previously found adequate to produce a reasonable allowance under the Internal Revenue Code of 1939 or prior revenue laws will, if used consistently by the taxpayer, continue to be acceptable under section 167(a). Examples of such methods which continue to be acceptable are the straight line method, the declining balance method with the rate limited to 150 percent of the applicable straight line rate, and under appropriate circumstances, the unit of production method. The methods described in section 167(b) and §§ 1.167(b)-1, 1.167(b)-2, 1.167(b)-3, and 1.167(b)-4 shall be deemed to produce a reasonable allowance for depreciation except as limited under section 167(c) and § 1.167(c)-1. See also § 1.167(e)-1 for rules relating to change in method of computing depreciation.
(c) Application of methods. In the case of item accounts, any method which results in a reasonable allowance for depreciation may be selected for each item of property, but such method must thereafter be applied consistently to that particular item. In the case of group, classified, or composite accounts, any method may be selected for each account. Such method must be applied to that particular account consistently thereafter but need not necessarily be applied to acquisitions of similar property in the same or subsequent years, provided such acquisitions are set up in separate accounts. See, however, § 1.167(e)-1 and section 446 and the regulations thereunder, for rules relating to changes in the method of computing depreciation, and § 1.167(c)-1 for restriction on the use of certain methods. See also § 1.167(a)-7 for definition of account.
§ 1.167(b)-1   Straight line method.
(a) In general. Under the straight line method the cost or other basis of the property less its estimated salvage value is deductible in equal annual amounts over the period of the estimated useful life of the property. The allowance for depreciation for the taxable year is determined by dividing the adjusted basis of the property at the beginning of the taxable year, less salvage value, by the remaining useful life of the property at such time. For convenience, the allowance so determined may be reduced to a percentage or fraction. The straight line method may be used in determining a reasonable allowance for depreciation for any property which is subject to depreciation under section 167 and it shall be used in all cases where the taxpayer has not adopted a different acceptable method with respect to such property.
(b) Illustrations. The straight line method is illustrated by the following examples:
1 In this example it is assumed that the assets were placed in service on July 1, 1954.
1954—Initial investment of $12,000.
1957—Retirement $2,000, salvage realized $200.
1958—Retirement $2,000, salvage realized $200.
1959—Retirement $4,000, salvage realized $400.
1959—Additions $10,000.
1960—Retirement $2,000, no salvage realized.
1961—Retirement $2,000, no salvage realized.

§ 1.167(b)-2   Declining balance method.
(a) Application of method. Under the declining balance method a uniform rate is applied each year to the unrecovered cost or other basis of the property. The unrecovered cost or other basis is the basis provided by section 167(g), adjusted for depreciation previously allowed or allowable, and for all other adjustments provided by section 1016 and other applicable provisions of law. The declining balance rate may be determined without resort to formula. Such rate determined under section 167(b)(2) shall not exceed twice the appropriate straight line rate computed without adjustment for salvage. While salvage is not taken into account in determining the annual allowances under this method, in no event shall an asset (or an account) be depreciated below a reasonable salvage value. However, see section 167(f) and § 1.167(f)-1 for rules which permit a reduction in the amount of salvage value to be taken into account for certain personal property acquired after October 16, 1962. Also, see section 167(c) and § 1.167(c)-1 for restrictions on the use of the declining balance method.
(b) Illustrations. The declining balance method is illustrated by the following examples:

Depreciation Reserve
1954 Acquisitions
1 Balance allowable as depreciation in the year of retirement of the last survivor of the 1954 acquisitions.
Depreciation Reserve for 1954 Acquisitions
1959 Acquisitions
(c) Change in estimated useful life. In the declining balance method when a change is justified in the useful life estimated for an account, subsequent computations shall be made as though the revised useful life had been originally estimated. For example, assume that an account has an estimated useful life of ten years and that a declining balance rate of 20 percent is applicable. If, at the end of the sixth year, it is determined that the remaining useful life of the account is six years, computations shall be made as though the estimated useful life was originally determined as twelve years. Accordingly, the applicable depreciation rate will be 16 2/3 percent. This rate is thereafter applied to the unrecovered cost or other basis.
