I. Accounting Methods

An “accounting method,” for federal income tax purposes, is a practice a taxpayer follows to determine the taxable year in which to report revenue and expenses for federal income tax purposes. An accounting method includes not only the overall plan of accounting for gross income or deductions (for example, an accrual method or the cash receipts and disbursement method), but also the treatment of any item that involves the proper time for the inclusion of an item in income or the taking of an item as a deduction, or both. However, a practice that does not affect the timing for reporting an item of income or deduction for purposes of determining taxable income is not an accounting method. A taxpayer, including a tax-exempt entity, generally adopts any permissible accounting method in the first year in which it uses the method in determining its taxable income. See Rev. Proc. 2015-13, 2015-5 I.R.B. 419 .

Caution: An exempt organization may adopt an accounting method not only for purposes of calculating taxable income but also for purposes of determining whether taxable income will be subject to federal income tax. For example, a tax-exempt entity may adopt an accounting method for an item of income from an unrelated trade or business activity even if the gross income from such activity is less than $1,000 and is therefore not taxed for federal income tax purposes pursuant to Regulations section 1.6012-2(e).

Instructions for Form 990-PF (2025) 7

An accounting method for an item of income or deduction may generally be adopted separately for each of the taxpayer’s trades or businesses. However, in order to be permissible, an accounting method must clearly reflect the taxpayer’s income. Unless instructed otherwise, the organization should generally use the same accounting method on the return (including the Form 990-PF and all schedules) to report revenue and expenses that it regularly uses to keep its books and records.

Accounting method change. Once a taxpayer, including a tax-exempt entity, adopts an accounting method for federal income tax purposes, the taxpayer must generally request the IRS’s consent before it can change its accounting method (even if the year in which the taxpayer seeks to make the change is a year in which it generates only tax-exempt income or is otherwise not taxed on its taxable income). In most cases, a taxpayer requests consent to change an accounting method by filing a Form 3115, Application for Change in Accounting Method. See Rev. Proc. 2015-13, or any successor, for general procedures for obtaining consent to change an accounting method.

Caution: Depending upon the specific accounting method change being requested, the taxpayer may be able to request “automatic” consent. This means that as long as the taxpayer follows the applicable procedures, the taxpayer does not have to wait for formal approval by the IRS before applying the new accounting method. See Rev. Proc. 2019-43, 2019-48 I.R.B. 1107, as modified by Rev. Proc. 2021-34, 2021-35 I.R.B. 337, or its successor, for a list of accounting method changes that generally qualify for automatic consent.

For example, a tax-exempt entity that has adopted an accounting method for an item of income from an unrelated trade or business must generally request consent before it can change its method of accounting for that item in any subsequent year. This is true regardless of whether gross income from the unrelated trade or business is greater than or equal to $1,000 in such subsequent year.

Alternatively, if a taxpayer, including a tax-exempt entity, has not yet adopted an accounting method for an item of income or deduction, a change in how the entity reports the item is not a change in accounting method. In this case, the procedures applicable to requests for accounting method changes (for example, the requirement to file a Form 3115) are not applicable.

Thus, a tax-exempt entity that has never taken into account an item of income or deduction in determining taxable income does not have to request consent to change its method of reporting that item on Form 990-PF. Additionally, a tax-exempt entity that has never been subject to federal income tax on an item of income or deduction but that is required to file a Form 990-T solely due to owing a section 6033(e)(2) proxy tax does not have to request consent to change its method for reporting the item.
