§ 301.7430-5 Prevailing party. ( a ) *In general.* For purposes of an award of reasonable administrative costs under section 7430 in the case of administrative proceedings commenced after July 30, 1996, a taxpayer is a prevailing party (other than by reason of section 7430(c)(4)(E)) only if— ( 1 ) At least one issue (other than recovery of administrative costs) remains in dispute as of the date that the Internal Revenue Service takes a position in the administrative proceeding, as described in paragraph (b) of this section;
( 2 ) The position of the Internal Revenue Service was not substantially justified;
( 3 ) The taxpayer substantially prevails as to the amount in controversy or with respect to the most significant issue or set of issues presented; and
( 4 ) The taxpayer satisfies the net worth and size limitations referenced in paragraph (f) of this section.
( b ) *Position of the Internal Revenue Service.* The position of the Internal Revenue Service in an administrative proceeding is the position taken by the Internal Revenue Service as of the earlier of— ( 1 ) The date of the receipt by the taxpayer of the notice of the decision of the Internal Revenue Service Office of Appeals; or
( 2 ) The date of the notice of deficiency or any date thereafter.
( c ) *Examples.* The provisions of this section may be illustrated by the following examples: Example 1. Taxpayer A receives a notice of proposed deficiency (30-day letter). A pays the amount of the proposed deficiency and files a claim for refund. A's claim is considered and a notice of proposed claim disallowance is issued by the Area Director. A does not request an Appeals office conference and the Area Director issues a notice of claim disallowance. A then files suit in a United States District Court. A cannot recover reasonable administrative costs because the notice of claim disallowance is not a notice of the decision of the Internal Revenue Service Office of Appeals or a notice of deficiency. Accordingly, the Internal Revenue Service has not taken a position in the administrative proceeding pursuant to section 7430(c)(7)(B).
Example 2. Taxpayer B receives a notice of proposed deficiency (30-day letter). B disputes the proposed adjustments and requests an Appeals office conference. The Appeals office determines that B has no additional tax liability. B requests administrative costs from the date of the 30-day letter. B is not the prevailing party and may not recover administrative costs because all of the proposed adjustments in the case were resolved as of the date that the Internal Revenue Service took a position in the administrative proceeding.
( d ) *Substantially justified* — ( 1 ) *In general.* The position of the Internal Revenue Service is substantially justified if it has a reasonable basis in both fact and law. A significant factor in determining whether the position of the Internal Revenue Service is substantially justified as of a given date is whether, on or before that date, the taxpayer has presented all relevant information under the taxpayer's control and relevant legal arguments supporting the taxpayer's position to the appropriate Internal Revenue Service personnel. The appropriate Internal Revenue Service personnel are personnel responsible for reviewing the information or arguments, or personnel who would transfer the information or arguments in the normal course of procedure and administration to the personnel who are responsible.
( 2 ) *Position in courts of appeal.* Whether the United States has won or lost an issue substantially similar to the one in the taxpayer's case in courts of appeal for circuits other than the one to which the taxpayer's case would be appealable should be taken into consideration in determining whether the Internal Revenue Service's position was substantially justified.
( 3 ) *Example.* The provisions of this section (d) are illustrated by the following example: Example. The Internal Revenue Service, in the conduct of a correspondence examination of taxpayer A's individual income tax return, requests substantiation from A of claimed medical expenses. A does not respond to the request and the Internal Revenue Service issues a notice of deficiency. After receiving the notice of deficiency, A presents sufficient information and arguments to convince a tax compliance officer that the notice of deficiency is incorrect and that A owes no tax. The revenue agent then closes the case showing no deficiency. Although A incurred costs after the issuance of the notice of deficiency, A is unable to recover these costs because, as of the date these costs were incurred, A had not presented relevant information under A's control and relevant legal arguments supporting A's position to the appropriate Internal Revenue Service personnel. Accordingly, the position of the Internal Revenue Service was substantially justified at the time the costs were incurred.
( 4 ) *Included costs.* ( i ) An award of reasonable administrative costs shall only include costs incurred on or after the administrative proceeding date as defined in section 301.7430-3(c) of this chapter.
( ii ) If the Internal Revenue Service takes a position in an administrative proceeding, as defined in paragraph (b) of this section, and the position is not substantially justified, the taxpayer may be permitted to recover costs incurred before the position was taken, but not before the dates set forth in this paragraph (d)(4).
( 5 ) *Examples.* The provisions of this section may be illustrated by the following examples: Example 1. Pursuant to section 6672, taxpayer D receives from the Area Director Collection Operations (Collection) a proposed assessment of trust fund taxes (Trust Fund Recovery Penalty). D requests and is granted Appeals office consideration. Appeals considers the issues and decides to uphold Collection's recommended assessment. Appeals notifies D of this decision in writing. Collection then assesses the tax and notice and demand is made. D timely pays the minimum amount required to commence a court proceeding, files a claim for refund, and furnishes the required bond. Collection disallows the claim, but Appeals, on reconsideration, reverses its original position, thus upholding D's position. If Appeals' initial determination was not substantially justified, D may recover administrative costs incurred on or after the mailing of the proposed assessment of trust fund taxes, because the proposed assessment is the first determination letter that allows the taxpayer an opportunity for administrative review in the Internal Revenue Service Office of Appeals.
Example 2. Taxpayer E receives a notice of proposed deficiency (30-day letter). E pays the amount of the proposed deficiency and files a claim for refund. E's claim is considered and a notice of proposed disallowance is issued by the Area Director. E requests and is granted Appeals office consideration. No agreement is reached with Appeals and the Office of Appeals issues a notice of claim disallowance. E does not file suit in a United States District Court but instead contacts the Appeals office to attempt to reverse the decision. E convinces the Appeals officer that the notice of claim disallowance is in error. The Appeals officer then abates the assessment. E may recover reasonable administrative costs if the position taken in the notice of claim disallowance issued by the Office of Appeals was not substantially justified and the other requirements of section 7430 and the regulations thereunder are satisfied. If so, E may recover administrative costs incurred from the mailing date of the 30-day letter because the requirements of paragraph (c)(2) of this section are met. E cannot recover the costs incurred prior to the mailing of the 30-day letter because they were incurred before the administrative proceeding date.
( 6 ) *Exception.* If the position of the Internal Revenue Service was substantially justified with respect to some issues in the proceeding and not substantially justified with respect to the remaining issues, any award of reasonable administrative costs to the taxpayer may be limited to only reasonable administrative costs attributable to those issues with respect to which the position of the Internal Revenue Service was not substantially justified. If the position of the Internal Revenue Service was substantially justified for only a portion of the period of the proceeding and not substantially justified for the remaining portion of the proceeding, any award of reasonable administrative costs to the taxpayer may be limited to only reasonable administrative costs attributable to that portion during which the position of the Internal Revenue Service was not substantially justified. Where an award of reasonable administrative costs is limited to that portion of the administrative proceeding during which the position of the Internal Revenue Service was not substantially justified, whether the position of the Internal Revenue Service was substantially justified is determined as of the date any cost is incurred.
( 7 ) *Presumption.* If the Internal Revenue Service did not follow any applicable published guidance in an administrative proceeding commenced after July 30, 1996, the position of the Internal Revenue Service, on those issues to which the guidance applies and for all periods during which the guidance was not followed, will be presumed not to be substantially justified. This presumption may be rebutted. For purposes of this paragraph (d)(7), the term *applicable published guidance* means final or temporary regulations, revenue rulings, revenue procedures, information releases, notices, and announcements published in the Internal Revenue Bulletin and, if issued to or with respect to the taxpayer, private letter rulings, technical advice memoranda, and determination letters (§ 601.601(d)(2) of this chapter). Also, for purposes of this paragraph (d)(7), the term administrative proceeding includes only those administrative proceedings or portions of administrative proceedings occurring on or after the administrative proceeding date as defined in § 301.7430-3(c).
( e ) *Amount in controversy.* The amount in controversy shall include the amount in issue as of the administrative proceeding date as increased by any amounts subsequently placed in issue by any party. The amount in controversy is determined without increasing or reducing the amount in controversy for amounts of loss, deduction, or credit carried over from years not in issue.
( f ) *Most significant issue or set of issues presented.* ( 1 ) *In general.* Where the taxpayer has not substantially prevailed with respect to the amount in controversy the taxpayer may nonetheless be a prevailing party if the taxpayer substantially prevails with respect to the most significant issue or set of issues presented. The issues presented include those raised as of the administrative proceeding date and those raised subsequently. Only in a multiple issue proceeding can a most significant issue or set of issues presented exist. However, not all multiple issue proceedings contain a most significant issue or set of issues presented. An issue or set of issues constitutes the most significant issue or set of issues presented if, despite involving a lesser dollar amount in the proceeding than the other issue or issues, it objectively represents the most significant issue or set of issues for the taxpayer or the Internal Revenue Service. This may occur because of the effect of the issue or set of issues on other transactions or other taxable years of the taxpayer or related parties.
( 2 ) *Example.* The provisions of this section may be illustrated by the following example: Example. In the purchase of an ongoing business, Taxpayer F obtains from the previous owner of the business a covenant not to compete for a period of five years. On audit of F's individual income tax return for the year in which the business was acquired, the Internal Revenue Service challenges the basis assigned to the covenant not to compete and a deduction taken as a business expense for a seminar attended by F. Both parties agree that the covenant not to compete is amortizable over a period of five years; however, the Internal Revenue Service asserts that the proper basis of the covenant is $25,000, while F asserts the basis is $50,000 and claims a deduction of $10,000 in the year in which the business was acquired. F deducted $12,000 for the seminar. The Internal Revenue Service determines that the deduction for the seminar should be disallowed entirely. In the notice of deficiency, the Internal Revenue Service adjusts the amortization deduction to reflect the change to the basis of the covenant not to compete, and disallows the seminar expense. Thus, of the two adjustments determined for the year under audit, the adjustment attributable to the disallowance of the seminar is larger than that attributable to the covenant not to compete. Due to the impact on the next succeeding four years, however, the covenant not to compete adjustment is the most significant issue to both F and the Internal Revenue Service.
( g ) *Net worth and size limitations* — ( 1 ) *Individuals.* A taxpayer who is a natural person meets the net worth and size limitations of this paragraph if the taxpayer's net worth does not exceed two million dollars. For purposes of determining net worth, individuals filing a joint return, and jointly incurring administrative or litigation costs shall have their net worth determined jointly, with all assets and liabilities treated as joint for purposes of the net worth evaluation, and applying a joint cap of four million dollars. Individuals who file a joint return, but incur separate administrative or litigation costs, by retaining separate representation, and/or seeking individual administrative review or petitioning the court individually, such as under section 6015, shall have their net worth determined separately, with only those assets and liabilities reasonably attributable to each spouse considered against separate caps of two million dollars per spouse.
( 2 ) *Estates and trusts.* An estate or a trust meets the net worth and size limitations of this paragraph if the estate or trust's net worth does not exceed two million dollars. The net worth of an estate shall be determined as of the date of the decedent's death provided the date of death is prior to the date the court proceeding is commenced. The net worth of a trust shall be determined as of the last day of the last taxable year involved in the proceeding.
( 3 ) *Others.* ( i ) A taxpayer that is a partnership, corporation, association, unit of local government, or organization (other than an organization described in paragraph (g)(4) of this section) meets the net worth and size limitations of this paragraph if, as of the administrative proceeding date: ( A ) The taxpayer's net worth does not exceed seven million dollars; and
( B ) The taxpayer does not have more than 500 employees.
( ii ) A taxpayer who is a natural person and owns an unincorporated business is subject to the net worth and size limitations contained in paragraph (g)(3)(i) of this section if the tax at issue (or any interest, additional amount, addition to tax, or penalty, together with any costs in addition to the tax) relates directly to the business activities of the unincorporated business.
( 4 ) *Special rule for charitable organizations and certain cooperatives.* An organization described in section 501(c)(3) exempt from taxation under section 501(a), or a cooperative association as defined in section 15(a) of the Agricultural Marketing Act, 12 U.S.C. 1141j(a) (as in effect on October 22, 1986), meets the net worth and size limitations of this paragraph if, as of the administrative proceeding date, the organization or cooperative association does not have more than 500 employees.
( 5 ) *Special rule for TEFRA partnership proceedings.* ( i ) In cases involving partnerships subject to the unified audit and litigation procedures of subchapter C of chapter 63 of the Internal Revenue Code (TEFRA partnership cases), the TEFRA partnership meets the net worth and size limitations requirements of this paragraph (g) if, on the administrative proceeding date— ( A ) The partnership's net worth does not exceed seven million dollars; and
( B ) The partnership does not have more than 500 employees.
( ii ) In addition, each partner requesting fees pursuant to section 7430 must meet the appropriate net worth and size limitations set forth in paragraph (g)(1), (g)(2), or (g)(3) of this section. For example, if a partner is an individual, his or her net worth must not exceed two million dollars as of the administrative proceeding date. If the partner is a corporation, its net worth must not exceed seven million dollars and it must not have more than 500 employees.
( 6 ) *Determining net worth.* For purposes of determining net worth under this paragraph (g), assets are valued based on the cost of their acquisition.
( h ) *Determination of prevailing party.* If the final decision with respect to the tax, interest, or penalty is made at the administrative level, the determination of whether a taxpayer is a prevailing party shall be made by agreement of the parties, or absent an agreement, by the Internal Revenue Service. See § 301.7430-2(c)(7) regarding the right to appeal the decision of the Internal Revenue Service denying (in whole or in part) a request for reasonable administrative costs to the Tax Court.
