Introduction›Part III. Administrative, Procedural, and Miscellaneous

SECTION 2. BACKGROUND

Internal Revenue Bulletin 1997-21 · 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 material item. A material item is any item that involves the proper time for the inclusion of the item in income or the taking of the item as a deduction. In determining whether a taxpayer’s accounting practice for an item involves timing, generally the relevant question is whether the practice permanently changes the amount of the taxpayer’s lifetime income. If the practice does not permanently affect the taxpayer’s lifetime income, but does or could change the taxable year in which income is reported, it involves timing and is therefore a method of accounting. See Rev. Proc. 91–31, 1991–1 C.B. 566.

(2) Although a method of accounting may exist under this definition without a pattern of consistent treatment of an item, a method of accounting is not adopted in most instances without consistent treatment. The treatment of a material item in the same way in determining the gross income or deductions in two or more consecutively filed 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 tax 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 the characterization of an item may also constitute a change in method of accounting if the change has the effect of shifting income from one period to another. For example, a change from treating an item as income to treating the item as a

deposit is a change in method of accounting. See Rev. Proc. 91–31.

(4) 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) 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 1.446–1T(e)(3)(i) requires that, 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 desires to make the proposed change.

.03 Terms and conditions of a method change . Section 1.446–1(e)(3)(ii) authorizes the Commissioner to 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 generally Rev. Rul. 90–38.

.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. 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 §§ 1.446–1T(e)(3)(i) 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 method 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 method . The Commissioner may determine that certain changes in method of accounting will be made without a § 481(a) adjustment, using a ‘‘cut-off method.’’ Under a cut-off method, 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, § 263A (which generally applies to costs incurred after December 31, 1986, for noninventory property), § 461(h) (which generally applies to amounts incurred on or after July 18, 1984), and § 1.446–3 (which applies to notional principal contracts entered into on or after December 13, 1993). Because no items are duplicated or omitted from income when a cut-off method is used to effect a change in accounting method, 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 Service exercises its discretion under §§ 446(e) and 481(c) in a manner that generally minimizes distortions of income across taxable years and on an annual basis. Accordingly, if a taxpayer requests to change from a method of accounting that clearly reflects income, the Service, in determining whether to consent to the taxpayer’s request, will weigh the need for consistency against the taxpayer’s reason for desiring to change its method of accounting.

.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.

.09 Penalties . Any otherwise applicable penalty 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 will not be imposed when a taxpayer changes from an impermissible method of accounting to a permissible one by complying with all the appropriate provisions of this revenue procedure.

.10 Change made as part of an ex- amination . 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 an accounting method under this revenue procedure, the change may be made by the district 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.
