SECTION 3. DEFINITIONS

Internal Revenue Bulletin 1997-21 · 2026-10-03 edition · updated 2026-10-04 · United States

.01 Taxpayer .

(1) In general . The term ‘‘taxpayer’’ has the same meaning as the term ‘‘person’’ defined in § 7701(a)(1) (rather than the meaning of the term ‘‘taxpayer’’ defined in § 7701(a)(14)).

(2) Consolidated group . For purposes of (a) sections 3.07(1), 3.08(1), 4.02(2) and 6.01 (taxpayer under examination), (b) sections 3.08(2), 4.02(3) and 6.02 (taxpayer before an appeals office), or (c) sections 3.08(3), 4.02(4) and 6.03 (taxpayer before a federal court), the term ‘‘taxpayer’’ includes a consolidated group.

.02 Filed . Any form (including a Form 3115), statement, or other document required to be filed under this revenue procedure is filed on the date it is mailed to the proper address (or an address similar enough to complete delivery). If the form, statement, or other document is not mailed (or the date it is mailed cannot be reasonably determined), it is filed on the date it is delivered to the Service.

.03 Mailed . The date of mailing will be determined under the rules of § 7502. For example, the date of mailing is the date of the U.S. postmark or the applicable date recorded or marked by a designated delivery service. See Notice 97–26, 1997–17 I.R.B. 6.

.04 Timely performance of acts . The rules of § 7503 apply when the last day for the taxpayer’s timely performance of any act (for example, filing a Form 3115, submitting additional information, returning a Consent Agreement (see section 8.11 of this revenue procedure), or holding a conference) falls on a Saturday, Sunday, or legal holiday. The performance of any act is timely if the act is performed on the next succeeding day that is not a Saturday, Sunday, or a legal holiday.

.05 Year of change . The year of change is the taxable year for which a change in method of accounting is effective, that is, the first taxable year the

new method is to be used, even if no affected items are taken into account for that year. The year of change is also the first taxable year for complying with all the terms and conditions set forth in the Consent Agreement.

.06 Section 481(a) adjustment period . The § 481(a) adjustment period is the applicable number of taxable years for taking into account the § 481(a) adjustment required as a result of the change in method of accounting. The year of change is the first taxable year in the adjustment period and the § 481(a) adjustment is taken into account ratably over the number of taxable years in the adjustment period. The applicable adjustment periods are set forth in sections 5.02(3) and 6.04 of this revenue procedure.

(a) Except as provided in section 3.07(2) of this revenue procedure, an examination of a taxpayer with respect to a federal income tax return begins on the date the taxpayer is contacted in any manner by a representative of the Service for the purpose of scheduling any type of examination of the return. An examination ends:

(i) in a case in which the Service accepts the return as filed, on the date of the ‘‘no change’’ letter sent to the taxpayer;

(ii) in a fully agreed case, on the earliest of the date the taxpayer executes a waiver of restrictions on assessment or acceptance of overassessment (for example, Form 870, 4549, or 4605), the date the taxpayer makes a payment of tax that equals or exceeds the proposed deficiency, or the date of the ‘‘closing’’ letter (for example, Letter 891 or 987) sent to the taxpayer; or (iii) in an unagreed or a partially agreed case, on the earliest of the date the taxpayer (or its representative) is notified by Appeals that the case has been referred to Appeals from Examination, the date the taxpayer files a petition in the Tax Court, the date on which the period for filing a petition with the Tax Court expires, or the date of the notice of claim disallowance.

(b) An examination does not end as a result of the early referral of an issue to Appeals under the provisions of Rev. Proc. 96–9, 1996–1 C.B. 575.

(c) An examination resumes on the date the taxpayer (or its representative) is notified by Appeals (or otherwise) that the case has been referred to Examination for reconsideration.

.07 Under examination .

(1) In general.

(2) Partnerships and S corpora- tions subject to TEFRA . For an entity (including a limited liability company), treated as a partnership or an S corporation for federal income tax purposes, that is subject to the TEFRA unified audit and litigation provisions for partnerships and S corporations, an examination begins on the date of the notice of the beginning of an administrative proceeding sent to the Tax Matters Partner/Tax Matters Person (TMP). An examination ends:

(a) in a case in which the Service accepts the partnership or S corporation return as filed, on the date of the ‘‘no adjustments’’ letter or the ‘‘no change’’ notice of final administrative adjustment sent to the TMP;

(b) in a fully agreed case, when all the partners, members, or shareholders execute a Form 870–P, 870–L, or 870–S; or (c) in an unagreed or a partially agreed case, on the earliest of the date the TMP (or its representative) is notified by Appeals that the case has been referred to Appeals from Examination, the date the TMP (or a partner, member, or shareholder) requests judicial review, or the date on which the period for requesting judicial review expires.

But see section 4.02(6) of this revenue procedure for certain rules that preclude an entity from requesting a change in accounting method. Also note that S corporations are not subject to the TEFRA unified audit and litigation provisions for taxable years beginning after December 31, 1996. See Small Business Job Protection Act of 1996, Pub. L. No. 104–188, § 1317(a), 110 Stat. 1755, 1787 (1996). .08 Issue under consideration .

(1) Under examination . A taxpayer’s method of accounting for an item is an issue under consideration for the taxable years under examination if the taxpayer receives written notification (for example, by examination plan, information document request (IDR), or notification of proposed adjustments or income tax examination changes) from the examining agent(s) specifically citing the treatment of the item as an issue under consideration. For example, a taxpayer’s method of pooling under the dollar-value, last-in first-out LIFO inventory method is an issue under consideration as a result of an examination plan that identifies LIFO pooling as a matter to be examined, but it is not an issue under consideration as a result of an examination plan that merely identi

13

fies LIFO inventories as a matter to be examined. Similarly, a taxpayer’s method of determining inventoriable costs under § 263A is an issue under consideration as a result of an IDR that requests documentation supporting the costs included in inventoriable costs, but it is not an issue under consideration as a result of an IDR that requests documentation supporting the amount of cost of goods sold reported on the return. The question of whether a method of accounting is an issue under consideration may be referred to the national office as a request for technical advice under the provisions of Rev. Proc. 97–2, 1997–1 I.R.B. 64 (or any successor). (2) Before an appeals office . A taxpayer’s method of accounting for an item is an issue under consideration for the taxable years before an appeals office if the treatment of the item is included as an item of adjustment in the examination report referred to Appeals or is specifically identified in writing to the taxpayer by Appeals.

(3) Before a federal court . A taxpayer’s method of accounting for an item is an issue under consideration for the taxable years before a federal court if the treatment of the item is included in the statutory notice of deficiency, the notice of claim disallowance, the notice of final administrative adjustment, the pleadings (for example, the petition, complaint, or answer) or amendments thereto, or is specifically identified in writing to the taxpayer by the counsel for the government.

.09 Change within the LIFO inven- tory method . A change within the LIFO inventory method is a change from one LIFO inventory method or sub-method to another LIFO inventory method or sub-method. A change within the LIFO inventory method does not include a change in method of accounting that could be made by a taxpayer that does not use the LIFO inventory method (for example, a method governed by § 471 or § 263A).
