You can accrue an expense for a future cost only when a present obligation to a third party already exists and the amount is reasonably estimable. Anticipating a cost is not the same as owing one, and accruing for future expenses that lack a current obligation violates GAAP. Even when GAAP lets you book the accrual, the Internal Revenue Code usually delays the tax deduction until economic performance occurs, so the entry on your books and the deduction on your return often land in different years.
The GAAP Test for Accruing an Expense
Two conditions have to be satisfied before you record an accrued expense. It must be probable that a liability exists as of the financial statement date, and the dollar amount must be reasonably estimable. Both parts matter. A company that receives raw materials on December 30 but doesn’t get the invoice until January still records that payable in December, because the goods are in the warehouse and the purchase order fixes the price.
The same two-part test governs less obvious obligations. If historical data shows a 2% failure rate on $1,000,000 in electronics sales, the company accrues $20,000 as a warranty liability at the time of sale. A pending lawsuit works the same way: once counsel determines that an unfavorable outcome is probable and the payout can be estimated, the liability goes on the balance sheet, even before any court order.
When the loss is only reasonably possible, or the amount cannot be estimated, GAAP requires footnote disclosure instead of an accrual. The disclosure describes the contingency and either estimates the potential loss or explains why no estimate is possible.
Future Costs You Cannot Accrue
Knowing a cost is coming does not create a present liability. A building owner who expects a $75,000 roof replacement in four years cannot accrue that expense today. No contractor has been hired, no contract has been signed, and no work has been performed. There is no obligation to a third party, only an anticipated need.
The same reasoning rules out accruing for planned equipment overhauls, facility upgrades, and similar long-term projects. Those are capital expenditures recognized when the work happens or when a binding commitment is made. Recording them early would artificially reduce current-year income, which is the kind of earnings manipulation accrual standards exist to prevent.
Why the Tax Deduction Often Waits
The IRS does not simply accept what your books show. Under IRC Section 461(h), a business cannot claim a tax deduction until it satisfies both the all-events test and the economic performance requirement.1Office of the Law Revision Counsel. 26 USC 461 – General Rule for Taxable Year of Deduction The all-events test asks whether the fact of liability is established and whether the amount can be determined with reasonable accuracy. Even when both answers are yes, the deduction still waits for economic performance.
When economic performance occurs depends on the type of liability:
- Services provided to you: as the other party performs the services. A $10,000 December payment for advertising to run in February generally cannot be deducted until February.
- Property provided to you: as you receive the property.
- Your use of someone else’s property: as you use it, such as renting equipment month by month.
- Torts, breach of contract, and workers’ compensation: only when you actually make the payment.2eCFR. 26 CFR 1.461-4 – Economic Performance
That last category is where book and tax treatment diverge sharply. A company might record a $500,000 litigation reserve on its GAAP financials the moment the loss becomes probable, but it cannot deduct any of it on the return until payments are made. The gap between the two creates deferred tax assets that have to be tracked year after year.
The Two Exceptions That Let You Deduct Sooner
The Recurring Item Exception
Under IRC Section 461(h)(3), a taxpayer can treat an expense as incurred in the current year even though economic performance has not yet occurred, if four conditions are met:1Office of the Law Revision Counsel. 26 USC 461 – General Rule for Taxable Year of Deduction
- The all-events test is satisfied by year-end.
- Economic performance occurs within 8½ months after the close of the tax year.3eCFR. 26 CFR 1.461-5 – Recurring Item Exception
- The expense is a type the business incurs regularly and treats consistently.
- The item is immaterial, or accruing it now produces a better match against related income.
Utilities, insurance premiums, and recurring service contracts are the typical candidates. A December electric bill paid in January can be deducted in December’s tax year. The exception carries a hard exclusion: it never applies to tort liabilities or workers’ compensation, which always wait for actual payment.
The 3½-Month Prepayment Rule
When you prepay for services or property, economic performance normally would not occur until the other party delivers. Treasury Regulations provide a shortcut: if you can reasonably expect delivery within 3½ months of your payment date, economic performance is treated as occurring when you pay.2eCFR. 26 CFR 1.461-4 – Economic Performance A December payment for consulting work expected in February qualifies. A December payment for a project running into the following fall does not.
Special Rules for Compensation and Related Parties
Employee accruals are among the most common year-end entries and carry their own timing rules. Under GAAP, an employer accrues a liability for vacation benefits employees have earned but not yet taken, provided the obligation stems from services already rendered, the rights vest or accumulate, payment is probable, and the amount can be estimated.4FASB. Summary of Statement No. 43 Sick pay and holidays generally do not require accrual until the employee is absent, unless the employer’s policy makes them vest or accumulate.
Year-end bonuses carry a tax trap. If you accrue a bonus in December, the IRS treats it as deferred compensation unless the employee receives payment within 2½ months after the close of your tax year, or March 15 for calendar-year taxpayers.5GovInfo. Treasury Regulation 1.404(b)-1T Miss the deadline and the deduction shifts to the year the bonus is actually paid.
Related-party accruals face a separate restriction. Under IRC Section 267(a)(2), if you accrue an expense owed to a related party who uses the cash method, you cannot deduct it until the related party includes the payment in income.6Office of the Law Revision Counsel. 26 USC 267 – Losses, Expenses, and Interest With Respect to Transactions Between Related Taxpayers In practice, you wait until you cut the check. If a calendar-year S corporation accrues a $50,000 management fee to its majority shareholder in December but pays in March, the deduction shifts to the following year. The rule reaches family members, controlling shareholders, commonly controlled businesses, and personal service corporations and their employee-owners.
Whether These Rules Apply to Your Business
Not every business is on the accrual method. The IRC requires C corporations, partnerships with C corporation partners, and tax shelters to use accrual accounting, but a large exception exists for smaller businesses. If your average annual gross receipts over the preceding three tax years do not exceed $32,000,000, the inflation-adjusted threshold for tax years beginning in 2026, you can use the cash method instead.7Office of the Law Revision Counsel. 26 USC 448 – Limitation on Use of Cash Method of Accounting8IRS. Revenue Procedure 2025-32 Sole proprietors and partnerships without corporate partners generally have no requirement to use accrual accounting regardless of revenue.
On the cash method, most of what is described above becomes irrelevant. You deduct expenses when you pay them. Businesses approaching the threshold should plan the transition well before they cross it.
What Happens If You Get It Wrong
On the financial reporting side, failing to record known liabilities or accruing items that do not meet the recognition criteria can produce audit adjustments, restatements, and a qualified or adverse audit opinion. For public companies, that kind of restatement often draws SEC scrutiny and shareholder litigation.
On the tax side, if an improper accrual leads to an underpayment, the IRS imposes an accuracy-related penalty of 20% of the underpayment attributable to negligence or disregard of the rules.9Office of the Law Revision Counsel. 26 USC 6662 – Imposition of Accuracy-Related Penalty on Underpayments The penalty rises to 40% for gross valuation misstatements, and interest runs from the original due date of the return. The combination of back taxes, penalty, and interest can easily exceed the timing benefit the business was trying to capture.
