63-3027. COMPUTING IDAHO TAXABLE INCOME OF MULTISTATE OR UNITARY CORPORATIONS. The Idaho taxable income of any multistate or unitary corporation transacting business both within and without this state shall be computed in accordance with the rules set forth in this section: (a) As used in this section, unless the context otherwise requires: (1) "Business income" means income arising from transactions and activity in the regular course of the taxpayer’s trade or business and includes income from the acquisition, management, or disposition of tangible and intangible property when such acquisition, management, or disposition constitutes integral or necessary parts of the taxpayer’s trade or business operations. Gains or losses and dividend and interest income from stock and securities of any foreign or domestic corporation shall be presumed to be income from intangible property, the acquisition, management, or disposition of which constitutes an integral part of the taxpayer’s trade or business; such presumption may only be overcome by clear and convincing evidence to the contrary. (2) "Commercial domicile" means the principal place from which the trade or business of the taxpayer is directed or managed. (3) "Compensation" means wages, salaries, commissions and any other form of remuneration paid to employees for personal services. (4) "Nonbusiness income" means all income other than business income. (5) "Sales" means all gross receipts of the taxpayer not allocated under subsections (d) through (h) of this section. (6) "State" means any state of the United States, the District of Columbia, the Commonwealth of Puerto Rico, any territory or possession of the United States, and any foreign country or political subdivision thereof. (b) Any taxpayer having income from business activity which is taxable both within and without this state shall allocate and apportion such net income as provided in this section. (c) For purposes of allocation and apportionment of income under this section, a taxpayer is taxable in another state if: (1) In that state he is subject to a net income tax, a franchise tax measured by net income, a franchise tax for the privilege of doing business, or a corporate stock tax; or (2) That state has jurisdiction to subject the taxpayer to a net income tax regardless of whether, in fact, the state does or does not. (d) Rents and royalties from real or tangible personal property, capital gains interest, dividends, or patent or copyright royalties, to the extent that they constitute nonbusiness income, shall be allocated as provided in subsections (e) through (h) of this section. Allocable nonbusiness income shall be limited to the total nonbusiness income received which is in excess of any related expenses which have been allowed as a deduction during the taxable year. In the case of allocable nonbusiness interest or dividends, related expenses include interest on indebtedness incurred or continued to purchase or carry assets on which the interest or dividends are nonbusiness income. (e) (1) Net rents and royalties from real property located in this state are allocable to this state. (2) Net rents and royalties from tangible personal property are allocable to this state: (i) If and to the extent that the property is utilized in this state, or (ii) In their entirety if the taxpayer’s commercial domicile is in this state and the taxpayer is not organized under the laws of or taxable in the state in which the property is utilized. (3) The extent of utilization of tangible personal property in a state is determined by multiplying the rents and royalties by a fraction, the numerator of which is the number of days of physical location of the property in the state during the rental or royalty period in the taxable year, and the denominator of which is the number of days of physical location of the property everywhere during all rental or royalty periods in the taxable year. If the physical location of the property during the rental or royalty period is unknown or unascertainable by the taxpayer, tangible personal property is utilized in the state in which the property was located at the time the rental or royalty payer obtained possession. (f) (1) Capital gains and losses from sales of real property located in this state are allocable to this state. (2) Capital gains and losses from sales of tangible personal property are allocable to this state if: (i) The property had a situs in this state at the time of the sale, or (ii) The taxpayer’s commercial domicile is in this state and the taxpayer is not taxable in the state in which the property had a situs. (3) Capital gains and losses from sales of intangible personal property are allocable to this state if the taxpayer’s commercial domicile is in this state, unless such gains and losses constitute business income as defined in this section. (g) Interest and dividends are allocable to this state if the taxpayer’s commercial domicile is in this state unless such interest or dividends constitute business income as defined in this section. (h) (1) Patent and copyright royalties are allocable to this state: (i) If and to the extent that the patent or copyright is utilized by the payer in this state, or (ii) If and to the extent that the patent or copyright is utilized by the payer in a state in which the taxpayer is not taxable and the taxpayer’s commercial domicile is in this state. (2) A patent is utilized in a state to the extent that it is employed in production, fabrication, manufacturing, or other processing in the state or to the extent that a patent product is produced in the state. If the basis of receipts from patent royalties does not permit allocation to states or if the accounting procedures do not reflect states of utilization, the patent is utilized in the state in which the taxpayer’s commercial domicile is located. (3) A copyright is utilized in a state to the extent that printing or other publication originates in the state. If the basis of receipts from copyright royalties does not permit allocation to states or if the accounting procedures do not reflect states of utilization, the copyright is utilized in the state in which the taxpayer’s commercial domicile is located. (i) (1) Notwithstanding the election allowed in article III.1 of the multistate tax compact enacted as section 63-3701, Idaho Code, all business income shall be apportioned to this state under subsection (j) of this section by multiplying the income by a fraction, the numerator of which is the property factor plus the payroll factor plus two (2) times the sales factor, and the denominator of which is four (4), except as provided in paragraph (2) of this subsection. (2) If a corporation, or a parent corporation of a combined group filing a combined report under sections 63-3027 and 63-3701, Idaho Code, is an electrical corporation as defined in section 61-119, Idaho Code, or is a telephone corporation as defined in section 62-603, Idaho Code, all business income of the corporation shall be apportioned to this state by multiplying the income by a fraction, the numerator of which is the property factor plus the payroll factor plus the sales factor, and the denominator of which is three (3). (j) (1) In the case of a corporation or group of corporations combined under subsection (t) of this section, Idaho taxable income or loss of the corporation or combined group shall be determined as follows: (i) From the income or loss of the corporation or combined group of corporations, subtract any nonbusiness income, and add any nonbusiness loss, included in the total, (ii) Multiply the amounts determined under paragraph (1)(i) of this subsection by the Idaho apportionment percentage defined in subsection (i) of this section, taking into account, where applicable, the property, payroll and sales of all corporations, wherever incorporated, which are included in the combined group. The resulting product shall be the amount of business income or loss apportioned to Idaho. (2) To the amount determined as apportioned business income or loss under paragraph (1)(ii) of this subsection, add nonbusiness income allocable entirely to Idaho under the provisions of this section or subtract nonbusiness loss allocable entirely to Idaho under this section. The resulting sum is the Idaho taxable income or loss of the corporation. (3) In the case of a corporation not subject to subsection (t) of this section, the income or loss referred to in paragraph (1)(i) of this subsection shall be the taxable income of the corporation after making appropriate adjustments under the provisions of section 63-3022, Idaho Code. (k) The property factor is a fraction, the numerator of which is the average value of the taxpayer’s real and tangible personal property owned or rented and used in this state during the tax period, and the denominator of which is the average value of all the taxpayer’s real and tangible personal property owned or rented and used during the tax period. (l) Property owned by the taxpayer is valued at its original cost. Property rented by the taxpayer is valued at eight (8) times the net annual rental rate. Net annual rental rate is the annual rental rate paid by the taxpayer less any annual rental rate received by the taxpayer from subrentals. (m) The average value of property shall be determined by averaging the values at the beginning and ending of the tax period, but the state tax commission may require the averaging of monthly values during the tax period if reasonably required to reflect properly the average value of the taxpayer’s property. (n) The payroll factor is a fraction, the numerator of which is the total amount paid in this state during the tax period by the taxpayer for compensation, and the denominator of which is the total compensation paid everywhere during the tax period. (o) Compensation is paid in this state if: (1) The individual’s service is performed entirely within the state; or (2) The individual’s service is performed both within and without the state, but the service performed without the state is incidental to the individual’s service within the state; or (3) Some of the service is performed in the state and: (i) The base of operations or, if there is no base of operations, the place from which the service is directed or controlled is in the state, or (ii) The base of operations or the place from which the service is directed or controlled is not in any state in which some part of the service is performed, but the individual’s residence is in this state. (p) The sales factor is a fraction, the numerator of which is the total sales of the taxpayer in this state during the tax period, and the denominator of which is the total sales of the taxpayer everywhere during the tax period. (q) Sales of tangible personal property are in this state if: (1) The property is delivered or shipped to a purchaser, other than the United States government, within this state regardless of the f.o.b. point or other conditions of the sale; or (2) The property is shipped from an office, store, warehouse, factory, or other place of storage in this state and: (i) The purchaser is the United States government, or (ii) The taxpayer is not taxable in the state of the purchaser. (r) Sales, other than sales of tangible property, are in this state, if: (1) The income-producing activity is performed in this state; or (2) The income-producing activity is performed both in and outside this state and a greater proportion of the income-producing activity is performed in this state than in any other state, based on costs of performance. (s) If the allocation and apportionment provisions of this section do not fairly represent the extent of the taxpayer’s business activity in this state, the taxpayer may petition for or the state tax commission may require, in respect to all or any part of the taxpayer’s business activity, if reasonable: (1) Separate accounting, provided that only that portion of general expenses clearly identifiable with Idaho business operations shall be allowed as a deduction; (2) The exclusion of any one (1) or more of the factors; (3) The inclusion of one (1) or more additional factors which will fairly represent the taxpayer’s business activity in this state; or (4) The employment of any other method to effectuate an equitable allocation and apportionment of the taxpayer’s income. (t) For purposes of this section and sections 63-3027B through 63-3027E, Idaho Code, the income of two (2) or more corporations, wherever incorporated, the voting stock of which is more than fifty percent (50%) owned directly or indirectly by a common owner or owners, when necessary to accurately reflect income, shall be allocated or apportioned as if the group of corporations were a single corporation, in which event: (1) The Idaho taxable income of any corporation subject to taxation in this state shall be determined by use of a combined report which includes the income, determined under paragraph (2) of this subsection, of all corporations which are members of a unitary business, allocated and apportioned using apportionment factors for all corporations included in the combined report and methods set out in this section. The use of a combined report does not disregard the separate corporate identities of the members of the unitary group. Each corporation which is transacting business in this state is responsible for its apportioned share of the combined business income plus its nonbusiness income or loss allocated to Idaho, minus its net operating loss carryover or carryback. (2) The income of a corporation to be included in a combined report shall be determined as follows: (i) For a corporation incorporated in the United States or included in a consolidated federal corporation income tax return, the income to be included in the combined report shall be the taxable income for the corporation after making appropriate adjustments under the provisions of section 63-3022, Idaho Code; (ii) For a corporation incorporated outside the United States, but not included in subsection (t)(2)(i) of this section, the income to be included in the combined report shall be the net income before income taxes of such corporation stated on the profit and loss statements of such corporation which are included within the consolidated profit and loss statement prepared for the group of related corporations of which the corporation is a member, which statement is prepared for filing with the United States securities and exchange commission. If the group of related companies is not required to file such profit and loss statement with the United States securities and exchange commission, the profit and loss statement prepared for reporting to shareholders and subject to review by an independent auditor may be used to obtain net income before income taxes. In the alternative, and subject to reasonable substantiation and consistent application by the group of related companies, adjustments may be made to the profit and loss statements of the corporation incorporated outside the United States, if necessary, to conform such statements to tax accounting standards as required by the Internal Revenue Code as if such corporation were incorporated in the United States and required to file a federal income tax return, subject to appropriate adjustments under the provisions of section 63-3022, Idaho Code;  (iii) If the income computation for a group under subparagraphs (i) and (ii) of this paragraph results in a loss, such loss shall be taken into account in other years, subject to the provisions of subsections (b) and (c) of section 63-3022, Idaho Code; and (iv) When one (1) or more corporations included in a combined report have excess inclusion income for a tax year that is taxable to those corporations pursuant to section 63-3011B, Idaho Code, the amount of such excess inclusion income shall be reported as the taxable income for those members of the combined group as provided by section 63-3011B, Idaho Code, and any net operating loss for that tax year or carried forward from an earlier tax year may be taken as deductions in other tax years, subject to the provisions of subsections (b) and (c) of section 63-3022, Idaho Code. In computing the net operating loss that may be used in another tax year for that corporation or other member of the combined return group, the excess inclusion income recognized as taxable income shall be deducted from gross income, as provided by treasury regulation 1.860E-1(a)(1). (u) If compensation is paid in the form of a reasonable cash fee for the performance of management services directly for the United States government at the Idaho national laboratory or any successor organization, separate accounting for that part of the business activity without regard to other activity of the taxpayer in the state of Idaho or elsewhere shall be required; provided that only that portion of general expenses clearly identifiable with Idaho business operations of that activity shall be allowed as a deduction.
