SECTION 2. BACKGROUND
Internal Revenue Bulletin 2008-36 · 2026-10-03 edition · updated 2026-10-04 · United States
.01 Change in method of accounting defined .
(1) Section 1.446–1(e)(2)(ii)( a ) provides that a change in method of accounting includes a change in the overall plan of accounting for gross income or deductions, or a change in the treatment of any
September 8, 2008 606 2008–36 I.R.B.
in the same way in determining the gross income or deductions in two or more consecutively filed federal income tax returns (without regard to any change in status of the method as permissible or impermissible) represents consistent treatment of that item for purposes of § 1.446–1(e)(2)(ii)( a ). If a taxpayer treats an item properly in the first return that reflects the item, however, it is not necessary for the taxpayer to treat the item consistently in two or more consecutive returns to have adopted a method of accounting. If a taxpayer has adopted a method of accounting under these rules, the taxpayer may not change the method by amending its prior income tax return(s). See Rev. Rul. 90–38, 1990–1 C.B. 57.
(3) A change in method of accounting does not include correction of mathematical or posting errors, or errors in the computation of tax liability (such as errors in computation of the foreign tax credit, net operating loss, percentage depletion, or investment credit). See § 1.446–1(e)(2)(ii)( b ).
.02 Securing permission to make a method change . Section 446(e) and § 1.446–1(e)(2)(i) state that, except as otherwise provided, a taxpayer must secure the consent of the Commissioner before changing a method of accounting for federal income tax purposes. Section 1.446–1(e)(3)(i) requires that, in general, in order to obtain the Commissioner’s consent to a method change, a taxpayer must file a Form 3115, Application for Change in Accounting Method, during the taxable year in which the taxpayer wants to make the proposed change.
.03 Terms and conditions of a method change . Section 1.446–1(e)(3)(ii) provides that the Commissioner may prescribe administrative procedures setting forth the limitations, terms, and conditions deemed necessary to permit a taxpayer to obtain consent to change a method of accounting in accordance with § 446(e). The terms and conditions the Commissioner may prescribe include the year of change, whether the change is to be made with a § 481(a) adjustment or on a cut-off basis, and the § 481(a) adjustment period.
.04 No retroactive method change . Unless specifically authorized by the Commissioner, a taxpayer may not request, or otherwise make, a retroactive change in method of accounting, regardless of
whether the change is from a permissible or an impermissible method. See gener- ally Rev. Rul. 90–38. But see section 6.02(3)(c)(i) of this revenue procedure. .05 Method change with a § 481(a) adjustment .
(1) Need for adjustment . Section 481(a) requires those adjustments necessary to prevent amounts from being duplicated or omitted to be taken into account when the taxpayer’s taxable income is computed under a method of accounting different from the method used to compute taxable income for the preceding taxable year. When there is a change in method of accounting to which § 481(a) is applied, income for the taxable year preceding the year of change must be determined under the method of accounting that was then employed, and income for the year of change and the following taxable years must be determined under the new method of accounting as if the new method had always been used. The § 481(a) adjustment is computed notwithstanding that the period of limitations on assessment and collection of tax may have closed on the years (closed years) in which the events giving rise to the need for an adjustment occurred. See Superior Coach of Fla., Inc. v. Commissioner, 80 T.C. 895, 912 (1983).
Example . A taxpayer that is not required to use inventories uses the overall cash receipts and disbursements method and changes to an overall accrual method. The taxpayer has $120,000 of income earned but not yet received (accounts receivable) and $100,000 of expenses incurred but not yet paid (accounts payable) as of the end of the taxable year preceding the year of change. A positive § 481(a) adjustment of $20,000 ($120,000 accounts receivable less $100,000 accounts payable) is required as a result of the change.
(2) Adjustment period . Section 481(c) and §§ 1.446–1(e)(3)(ii) and 1.481–4 provide that the adjustment required by § 481(a) may be taken into account in determining taxable income in the manner and subject to the conditions agreed to by the Commissioner and the taxpayer. Generally, in the absence of such an agreement, the § 481(a) adjustment is taken into account completely in the year of change, subject to § 481(b), which limits the amount of tax where the § 481(a) adjustment is substantial. However, under the Commissioner’s authority in § 1.446–1(e)(3)(ii) to prescribe terms and conditions for changes in methods of accounting, this revenue procedure provides
specific adjustment periods that are intended to achieve an appropriate balance between the goals of mitigating distortions of income that result from accounting method changes and providing appropriate incentives for voluntary compliance.
.06 Method change using a cut-off ba- sis . The Commissioner may determine that certain changes in methods of accounting will be made without a § 481(a) adjustment, using a cut-off basis. When a change in method of accounting is made on a cut-off basis, in general, only the items arising on or after the beginning of the year of change (or other operative date) are accounted for under the new method of accounting. Any items arising before the year of change (or other operative date) continue to be accounted for under the taxpayer’s former method of accounting. See, for example, sections 2.01, 10.04 and 22.02 of the APPENDIX of this revenue procedure. Because no amounts are duplicated or omitted when a change in method of accounting is made on a cut-off basis, no § 481(a) adjustment is necessary.
.07 Consistency and clear reflection of income . Methods of accounting should clearly reflect income on a continuing basis, and the Commissioner exercises discretion under §§ 446(e) and 481(c) in a manner that generally minimizes distortions of income across taxable years and on an annual basis.
.08 Separate trades or businesses . (1) Sections 1.446–1(d)(1) and (2) provide that when a taxpayer has two or more separate and distinct trades or businesses, a different method of accounting may be used for each trade or business provided the method of accounting used for each trade or business clearly reflects the overall income of the taxpayer as well as that of each particular trade or business. No trade or business is separate and distinct unless a complete and separable set of books and records is kept for that trade or business.
(2) Section 1.446–1(d)(3) provides that if, by reason of maintaining different methods of accounting, there is a creation or shifting of profits or losses between the trades or businesses of the taxpayer (for example, through inventory adjustments, sales, purchases, or expenses) so that income of the taxpayer is not clearly reflected, the trades or businesses of the taxpayer are not separate and distinct.
2008–36 I.R.B. 607 September 8, 2008
.09 Penalties . Any otherwise applicable penalty, addition to the tax, or additional amount for the failure of a taxpayer to change its method of accounting (for example, the accuracy-related penalty under § 6662 or the fraud penalty under § 6663) may be imposed if the taxpayer does not timely file a request to change a method of accounting. See § 446(f). Additionally, the taxpayer’s return preparer may also be subject to the preparer penalty under § 6694. However, penalties, additions to the tax, or additional amounts will not be imposed when a taxpayer changes from an impermissible method of accounting to a permissible one by complying with all applicable provisions of this revenue procedure.
.10 Change made as part of an examination . Section 446(b) and § 1.446–1(b)(1) provide that if a taxpayer does not regularly employ a method of accounting that clearly reflects its income, the computation of taxable income must be made in a manner that, in the opinion of the Commissioner, does clearly reflect income. If a taxpayer under examination is not eligible to change a method of accounting under this revenue procedure, the change may be made by the director. A change resulting in a positive § 481(a) adjustment will ordinarily be made in the earliest taxable year under examination with a one-year § 481(a) adjustment period. See Rev. Proc. 2002–18, 2002–1 C.B. 678.
