All-events test and economic performance: when an accrued liability is deductible

Reviewed 2026-09-15 · AI-assisted draft and editing; sources and limitations remain visible for independent review.

Answer: An accrual-method taxpayer incurs a liability, and generally takes it into account, in the taxable year in which three things are true: all the events have occurred that establish the fact of the liability, the amount can be determined with reasonable accuracy, and economic performance has occurred. The first two are the classic all-events test, restated in section 461(h)(4). The third was added by section 461(h)(1), which provides that the all-events test is not treated as met any earlier than when economic performance occurs, and it is where most year-end accruals actually fail. Economic performance has no single trigger; it is routed by the kind of liability. Where another person provides services or property to the taxpayer, performance tracks the providing. Where the taxpayer must provide services or property, it tracks the costs the taxpayer incurs. For a defined list that includes workers compensation and tort liabilities, rebates, prizes, insurance and warranty and service contracts, and taxes, performance occurs only as payment is made to the person owed. The recurring item exception in section 461(h)(3) can pull an item back into the earlier year, but only if four conditions are met, and it is unavailable for several of those same categories.

1. Three conditions, and the third is where accruals fail

Reg. section 1.461-1(a)(2)(i) states the composite rule for accrual-method taxpayers: a liability is incurred, and generally taken into account, in the taxable year in which all the events have occurred that establish the fact of the liability, the amount can be determined with reasonable accuracy, and economic performance has occurred. Keep the three separate in the workpaper, because they fail for different reasons and the cure for one is not the cure for another.

Fact of the liability is about whether the obligation exists as of year end, not whether it has been billed. Reasonable accuracy is about determinability, not certainty, and an estimate supported by a reliable basis can satisfy it. Economic performance is about whether the underlying activity has happened, and it is not satisfied by accrual, invoicing, or board approval. Section 461(h)(1) is drafted to make that explicit: the all-events test is not treated as met any earlier than the year in which economic performance occurs.

2. Route the liability to its economic performance rule

Section 461(h)(2) and Reg. section 1.461-4 sort liabilities by their source, and the trigger differs in each lane. Where the liability arises out of another person providing services or property to the taxpayer, Reg. section 1.461-4(d)(2)(i) puts economic performance as the services or property are provided. Where the liability arises out of the taxpayer's use of property, do not stop at the statute's words: section 461(h)(2)(A)(iii) says performance occurs as the taxpayer uses the property, but Reg. section 1.461-4(d)(3)(i) makes it ratable over the period the taxpayer is entitled to the use, with Reg. section 1.461-4(d)(3)(ii)(A) carving out the portion measured by frequency or volume of use or by income from the property. Where the liability requires the taxpayer to provide services or property to someone else, Reg. section 1.461-4(d)(4)(i) puts economic performance as the taxpayer incurs costs in connection with satisfying it. Interest is separate again: under Reg. section 1.461-4(e) economic performance occurs as the interest cost economically accrues.

Two refinements inside the services-and-property lane are worth knowing. Reg. section 1.461-4(d)(6)(i) treats services or property provided to another person at the taxpayer's direction as provided to the taxpayer. And Reg. section 1.461-4(d)(6)(ii) permits a taxpayer to treat services or property as provided when it makes payment, if it can reasonably expect the provider to perform within three and a half months after the date of payment. That is a permitted treatment, not an automatic one, and choosing it is a method decision.

A short hypothetical shows why routing comes first. A calendar-year business signs a year-end agreement under which a vendor will service equipment next spring, and separately owes a settlement in a contract dispute. The two liabilities sit in different lanes: the service obligation follows the provision of services, the settlement follows payment. Nothing about the size of the accrual or its presence in the closing entries changes that routing.

3. The payment lane is broader than it looks

Reg. section 1.461-4(g) gathers the liabilities for which payment itself is economic performance. The list reaches liabilities arising under a workers compensation act or out of any tort, breach of contract, or violation of law; rebates and refunds, including a rebate delivered as a price reduction; awards, prizes and jackpots; insurance, warranty and service contracts provided to the taxpayer; taxes; and a residual category of other liabilities for which no rule is provided elsewhere.

The paragraph also controls who must be paid. Under Reg. section 1.461-4(g)(1)(i), economic performance occurs when and to the extent payment is made to the person to which the liability is owed, and payments to a trust, escrow account, court-administered fund or similar arrangement do not qualify unless they constitute payment to that person. Funding a reserve, however well documented, is therefore not economic performance for these liabilities. That single rule disposes of a large share of disputed year-end accruals.

4. The recurring item exception is a four-part gate

Reg. section 1.461-5(b)(1) sets four conditions, and all four must hold. As of the end of the taxable year, all events must have occurred that establish the fact of the liability and the amount must be determinable with reasonable accuracy. Economic performance must occur on or before the earlier of the date the taxpayer files a timely return for that year, including extensions, or the fifteenth day of the ninth calendar month after the close of the year. The liability must be recurring in nature. And either the amount must not be material, or accruing it in that year must produce a better matching of the liability with the income to which it relates.

Each condition has a definition worth reading rather than assuming. Reg. section 1.461-5(b)(3) treats a liability as recurring if it can generally be expected to be incurred from one year to the next, allows a liability that is not incurred every year to qualify, and even permits a liability never previously incurred to qualify where recurrence is reasonably expected. Reg. section 1.461-5(b)(4) says materiality considers the amount both in absolute terms and against other income and expense of the same activity, treats an item material for financial statement purposes as material here, and warns that an item immaterial for financial statement purposes may still be material for this test. Reg. section 1.461-5(b)(5) says financial reporting principles are an important factor in the matching analysis but are not dispositive, while deeming the matching requirement satisfied for several enumerated liability types.

Reg. section 1.461-5(b)(2) adds a practical route: a taxpayer may file an amended return treating a liability as incurred under the exception where economic performance occurs after the original return was filed but within eight and a half months after the close of the year. The exception is also an adopted method of accounting under Reg. section 1.461-5(a), applied to types of recurring items, not a year-by-year choice.

5. Liabilities the exception cannot reach

Reg. section 1.461-5(c) puts three liability types outside the exception entirely: interest under Reg. section 1.461-4(e); liabilities arising under a workers compensation act or out of tort, breach of contract or violation of law under Reg. section 1.461-4(g)(2); and the residual other liabilities under Reg. section 1.461-4(g)(7). The same paragraph adds an exclusion that turns on the taxpayer rather than the liability: the exception does not apply to any liability incurred by a tax shelter as defined in section 461(i). For those, payment in the following year does not reach back, and the deduction waits for the year of actual economic performance.

The residual category deserves a second look before a position is taken. Reg. section 1.461-5(a) notes that for the other payment liabilities described in Reg. section 1.461-4(g)(7), the Commissioner may provide for application of the exception by regulation, revenue procedure or revenue ruling. So the exclusion is the default rather than an absolute, and published guidance for the specific liability type should be checked.

6. Turning the analysis into a year-end accrual schedule

A workpaper that survives review lists each accrued liability with five columns of research facts: the source of the obligation in enough detail to route it; the date the fact of liability was established; the basis for the amount and its reliability; the economic performance trigger and the date it occurred or is expected; and, where the recurring item exception is relied on, each of the four conditions answered separately with the materiality or matching rationale stated. Record the filing date used for the exception's outer limit, because that date, not the ninth-month date, often controls.

This page is the deduction-side companion to Section 451 income timing: the AFS inclusion rule and advance payments in the same cluster; note that the all-events test for income has no economic performance requirement, so the two sides are not symmetrical. Ask Taxterity a research question for each liability type on your accrual schedule, then verify the routing regulation and the recurring-item conditions against the current text before the return position is finalized.
