Accrual Accounting: Definition, Examples, and Controls
Learn how accrual accounting recognizes earned revenue and incurred expenses, how it differs from cash accounting, and how to control estimates.
Accrual accounting records the economic effect of transactions in the period in which revenue is earned and expenses are incurred, even when cash moves in another period. It uses receivables, payables, prepaid expenses, deferred revenue, accrued liabilities, and other accounts to connect performance with the correct reporting period.
This method can show operating performance and obligations more clearly than a cash-only view, but it requires disciplined cutoff, estimates, reconciliations, and reversals. Financial-statement accounting and federal income-tax accounting are related but not identical. Confirm the method permitted for the entity and transaction.
Accrual versus cash accounting
| Event | Accrual view | Cash view |
|---|---|---|
| Invoice issued after service is earned | Revenue and receivable may be recognized | Income generally waits for receipt, subject to tax rules |
| Vendor service received before bill or payment | Expense and accrued liability may be recognized | Expense generally waits for payment, subject to tax rules |
| Customer prepays future work | Cash and a contract or deferred-revenue liability may arise | Tax timing requires separate analysis |
| Annual insurance paid in advance | Prepaid asset is released over covered periods | Deduction timing depends on applicable tax rules |
The IRS explains cash and accrual methods in Publication 538 and notes that method rules, inventories, special items, and changes can affect the tax result. Do not assume that an accrual-book financial statement determines when an item appears on the return.
Revenue example
A consulting business completes a $6,000 approved milestone on March 28, issues the invoice April 2, and receives cash April 20. If the performance obligation was satisfied in March and the amount is collectible under the applicable framework, March accrual statements may record a receivable and revenue. April records the invoice through the billing workflow and then clears the receivable when cash arrives.
The business must prevent duplication between an unbilled-revenue accrual and the later invoice. Use a project or contract identifier, reverse or reclassify the accrual, and reconcile unbilled balances to billing after each close.
Expense example
A subcontractor performs March work but sends a $4,000 invoice in April. March accrual statements may record subcontractor expense and an accrued liability based on approved evidence. When the bill arrives, it replaces or clears the estimate rather than creating a second expense.
The support should show the service period, vendor, contract or rate, quantity, calculation, approver, and expected invoice date. Review the difference between estimate and final bill and use it to improve future accruals.
Common accrual accounts
- Accounts receivable: earned or billed customer amounts not yet collected.
- Accounts payable: approved vendor amounts not yet paid.
- Accrued expenses: incurred costs not yet entered through a vendor bill.
- Prepaid expenses: payments initially recorded as assets and released over benefit periods.
- Deferred or unearned revenue: customer consideration received before the associated performance is complete.
- Unbilled revenue: earned amounts not yet invoiced, subject to the contract and accounting policy.
- Depreciation and amortization: systematic allocation of qualifying asset cost.
- Allowance accounts: supported estimates of collectibility, returns, or other reductions.
Month-end accrual workflow
- Set the close date, materiality guidance, responsibilities, and cutoff calendar.
- Collect open purchase orders, receiving records, unbilled vendor work, payroll data, customer contracts, delivery evidence, and prepaid schedules.
- Identify earned revenue, incurred expense, deposits, deferrals, and estimates not captured by routine entries.
- Prepare each entry with account, period, amount, method, evidence, reversal, and owner.
- Obtain independent approval and post through a controlled journal-entry process.
- Reconcile balance-sheet accounts and review income-statement trends.
- Reverse or clear estimates when actual invoices, payroll, or billing posts.
- Compare estimate with actual and document significant differences.
Cutoff is central
Cutoff determines which period receives a transaction. Review shipments, service dates, time records, customer acceptance, vendor receipts, payroll dates, returns, credit memos, and deposits around period-end. The bank date by itself may not identify when revenue was earned or an expense incurred.
Use a consistent policy. Do not accelerate revenue or delay expenses to reach a target. Unusual period-end entries, round-dollar accruals, manual revenue, and reversals that do not occur should receive additional review.
Controls over estimates
Every material estimate should identify the source population, method, assumptions, exclusions, preparer, reviewer, historical accuracy, and later true-up. Reconcile schedules to the ledger and retain the version used for the close.
Age accruals and unbilled balances. Old items may represent a missing invoice, canceled obligation, uncollectible amount, duplicate entry, contract dispute, or failure to reverse. Do not roll an unsupported estimate forward indefinitely.
Benefits and limitations
Accrual reporting can show customer debt, vendor obligations, recurring profitability, margins, and period performance before cash settles. It supports forecasting and reduces the distortion caused by paying several months at once or collecting deposits before delivery.
However, profit is not cash. A profitable accrual statement can coexist with overdue receivables, inventory investment, loan payments, or tax obligations. Prepare a cash-flow forecast and reconcile cash separately. Accrual estimates can also be manipulated or simply wrong without effective review.
Tax accounting method
Federal tax rules determine whether a taxpayer may or must use a cash, accrual, or other authorized method for particular items. Inventory, advance payments, long-term contracts, interest, related parties, and method changes can receive special treatment. State rules may differ.
A change in tax accounting method may require IRS procedures and an adjustment rather than simply changing a software setting. Coordinate the books, tax workpapers, and returns with a qualified tax professional and preserve a reconciliation of book-tax differences.
Compare cash versus accrual accounting, establish reliable accrual bookkeeping, and control accrued expenses during each close.
Frequently asked questions
What is accrual accounting in simple terms?
It records revenue when earned and expenses when incurred, using assets and liabilities when cash is received or paid in a different period.
Does accrual accounting count unpaid invoices as income?
Financial statements may recognize earned, collectible revenue before payment, but the contract, accounting framework, collectibility, and tax method matter.
Is accrual accounting required?
Requirements depend on the reporting framework, business facts, tax rules, lender or investor needs, and sometimes industry or regulatory obligations.
What is an accrual entry?
It is a supported journal entry that recognizes an earned revenue or incurred expense before the related routine invoice, bill, or cash event posts.
Do accruals reverse?
Many operational accruals reverse in the next period or clear against an actual transaction, while other adjustments follow their specific schedule and policy.
Can I use accrual books and cash-basis taxes?
Sometimes, but eligibility and item-specific rules apply. Maintain book-tax reconciliations and confirm the permitted tax method with a qualified professional.
