Bonus accrual accounting under U.S. GAAP requires you to record employee bonus expense in the period the employee earned it, not the period you cut the check. The liability goes on the books once payment is probable and the amount is reasonably estimable, and it stays there as “Accrued Bonus Payable” until cash goes out. Get the timing wrong and you overstate profit in the earning year, understate it in the payment year, and, on the tax side, risk losing the deduction entirely.
When the Obligation Must Hit the Books
Two GAAP standards govern the timing. ASC 710 (Compensation—General) covers most employee bonus and profit-sharing plans. ASC 450 (Contingencies) picks up obligations that depend on uncertain future events. Both land on the same core test: the obligation must be probable and reasonably estimable.
Under ASC 710, four conditions must all be satisfied before you accrue:
- Employees have already performed the services that entitle them to the bonus.
- Their rights vest or accumulate rather than being wiped out at management’s discretion.
- Payment is probable, which a consistent history of paying bonuses under similar conditions helps support.
- The amount is reasonably estimable using year-to-date results, historical payout ratios, and plan terms.
When all four are met at the close of the period, you record the liability. Not knowing the exact final payout is not a reason to skip the accrual; a reasonable estimate is what the standard asks for.
ASC 450 applies when a bonus turns on an uncertain outcome, such as hitting a revenue target that is still in doubt. Same probable-and-estimable test. If you can determine only a range and no figure within the range is more likely than any other, accrue the low end. If the obligation is possible but not probable, no accrual is recorded, but the potential obligation is disclosed in the footnotes.
How to Calculate and Book the Entry
Start with the best data you have at period-end. A common approach: project year-end net income and apply the bonus pool percentage from the plan. Projected net income of $10 million and a plan that commits 8% to bonuses produces an $800,000 accrual.
The entry at period-end:
- Debit Bonus Expense $800,000
- Credit Accrued Bonus Payable $800,000
When you pay in the next period, the liability clears:
- Debit Accrued Bonus Payable $800,000
- Credit Cash $800,000
True-Up Adjustments
Actual payouts rarely match estimates to the penny. The difference runs through the current period, not by restating the prior year. If you accrued $800,000 but paid $820,000:
- Debit Accrued Bonus Payable $800,000
- Debit Bonus Expense $20,000
- Credit Cash $820,000
An over-accrual reverses the same way, crediting bonus expense in the current period. These true-ups are normal accrual accounting and do not signal an error in the prior estimate, provided the original figure was reasonable given the information you had.
Spreading the Accrual Over a Service Period
Many bonus plans require the employee to stay through the payment date or a defined service period. A bonus tied to a full calendar year of service accrues ratably over that year, not all at once in December. Each month worked, a proportional slice of the expected bonus becomes expense.
If an employee leaves before satisfying the service condition, previously accrued cost is reversed. The reversal is recorded in the period of the forfeiture, or, if company policy estimates forfeitures, when the estimate is updated for a higher expected departure rate.
Retention bonuses work the same way. A two-year, $50,000 retention bonus is recognized at $2,083 per month across 24 months. If the employee quits in month 14, the $29,167 recognized through that point is reversed.
How Bonus Type Changes the Answer
Performance-Based Bonuses
Performance bonuses carry objective, measurable targets communicated in advance: revenue goals, EBITDA thresholds, individual KPIs. The accrual question turns on whether hitting those targets is probable. Tracking at 120% of the annual revenue goal with one quarter left supports an accrual. Tracking at 40% with one quarter left generally does not. Probability is reassessed each reporting date. Performance surging in Q3 after a weak Q2 means catching up on the accrual in Q3; targets becoming unlikely mean reversing previously recognized expense.
Discretionary Bonuses
A purely discretionary bonus is one where management has made no commitment and retains full control until after the period ends. No obligation exists at the balance sheet date, so the probable test fails and no accrual is recorded. Expense hits the income statement when management formally commits or when cash goes out.
Be careful here. A company that has paid a “discretionary” year-end bonus for fifteen consecutive years, and whose employees reasonably expect it, may be found to have a constructive obligation. History can convert a nominally discretionary bonus into one that is probable, and an auditor may require an accrual.
Sign-On Bonuses With Clawbacks
A sign-on bonus with a clawback the company can enforce if the employee leaves within the first year is spread across that year rather than expensed at the hire date.
Quarterly Reporting Adjustments
Interim reporters face an extra question: how much of the annual pool belongs in each quarter? Estimate the annual bonus and allocate a proportional share to each quarter based on revenue or another rational method. A projected $1.2 million annual pool with revenue spread evenly gives each quarter $300,000 of bonus expense.
When performance shifts mid-year, the estimate shifts with it. Quarterly statements should reflect the current estimate of the annual bonus, and any catch-up for prior quarters flows through the current quarter’s expense. Q3 and Q4 bonus expense can look lumpy, and that lumpiness accurately reflects when new information arrived.
Don’t Skip the Payroll Tax Accrual
When you accrue a bonus, accrue the employer’s share of payroll taxes on it too. Social Security tax at 6.2% up to the annual wage base, Medicare tax at 1.45%, and federal and state unemployment taxes all apply. If an employee has already exceeded the Social Security wage base through regular pay, accrue only Medicare and unemployment. Skipping this step understates both expense and liability, and auditors flag it consistently.
Tax Deduction Timing
GAAP tells you when the expense appears on the income statement. The tax code tells you when the employer can deduct it. The two rules do not always agree, and the gap creates deadlines you cannot afford to miss.
The All-Events Test and Economic Performance
An accrual-method employer can deduct a bonus only after all events establishing the liability have occurred, the amount is determinable with reasonable accuracy, and economic performance has taken place. For compensation, economic performance generally happens as the employee provides the services.
The 8½-Month Recurring Item Exception
Most accrued bonuses are paid after year-end, which would ordinarily push the deduction into the payment year. The recurring item exception under IRC §461(h)(3) lets you deduct the bonus in the year earned if four conditions are met:
- The all-events test is met by year-end, meaning the liability is fixed and the amount determinable.
- The bonus is actually paid within 8½ months after the close of the tax year (September 15 for calendar-year filers).
- Bonuses are recurring in nature and consistently treated this way for tax purposes.
- Deducting in the earning year better matches the related income, or the amount is not material.
Miss the 8½-month window and the deduction shifts to the year the bonus is actually paid. A company that accrues $3 million at year-end but does not cut checks until October loses the deduction in the accrual year; it slides into the next tax year. The GAAP expense stays put, so a temporary difference appears on the balance sheet as a deferred tax asset.1Office of the Law Revision Counsel. 26 U.S. Code 461 – General Rule for Taxable Year of Deduction
The 2½-Month Deferred Compensation Line
Bonuses paid more than 2½ months after the close of the employer’s tax year risk being reclassified as deferred compensation under IRC §404. If that happens, the deduction is not allowed until the year the employee actually receives the payment, regardless of when the services were performed. Bonuses paid inside the 2½-month window are treated as ordinary compensation, and the recurring item exception above can still apply. Bonuses paid after that window may fall under the more restrictive deferred compensation rules.2eCFR. 26 CFR 1.404(b)-1 – Method of Contribution Having the Effect of a Plan
Related-Party Bonuses
Bonuses to owners, family members, and other related parties face tighter limits. Under IRC §267, an accrual-method employer cannot deduct compensation owed to a related cash-method recipient until the recipient includes it in income, which usually means the payment year. Accrue a $200,000 bonus for the majority shareholder in December, pay it in March, and no deduction is available in the accrual year. Closely held businesses run into this often because the bonus recipient frequently also holds a significant ownership stake.
Documentation Auditors Expect
Bonus accruals involve judgment and estimates, and documentation is what shows the recognition criteria were actually met. At a minimum, keep the written bonus plan or board resolution establishing the program, the specific performance targets and how they were set, year-to-date financial data showing progress toward those targets, the methodology behind the accrual estimate, and a comparison of the estimate to prior-year actual payouts. A history of accrued amounts that materially differ from actual payouts invites harder questions on the current estimate.

Compensation charges must be supported by internal controls providing reasonable assurance that amounts are accurate, and budget-based estimates require periodic after-the-fact review to confirm the final figures.3eCFR. 2 CFR 200.430 – Compensation Personal Services
