What Is Accrual Basis Accounting?
Recognize revenue and expenses when earned or incurred, not only when cash moves.
Detailed Explanation
Matches invoices to periods they belong to. Required for many larger or incorporated entities.
Example
You book December revenue when you invoice, even if paid in January.
Why It Matters
True profitability versus misleading cash timing.
Key facts
- Accrual-basis accounting recognizes revenue when earned and expenses when incurred — regardless of when cash actually moves.
- Required by U.S. GAAP and IFRS for most public companies, audited financial statements, and businesses over the IRS gross-receipts threshold ($30M in 2026).
- Accrual provides a more accurate view of profitability and operational performance than cash basis, but is more complex to maintain.
- Key accrual concepts: accounts receivable, accounts payable, accrued expenses, deferred revenue, and prepaid expenses.
- Accrual is required if you carry inventory (with limited small-business exceptions) or if you operate as a C-corp.
How it shows up in practice
A 25-person agency completes a $48,000 project in March 2026, invoices the client on April 1, and receives payment on May 20. Under accrual accounting, the full $48,000 is March revenue (recognized when earned) and creates accounts receivable for April. This matches revenue to the period when work was actually performed — giving the team a true picture of March's profitability rather than spreading it artificially across two months.
Common mistakes
- Forgetting to record accrued expenses at month-end (e.g., utilities used but not yet billed) — overstates monthly profit.
- Not deferring revenue received in advance (e.g., annual subscriptions) — overstates current-period revenue.
- Mixing cash- and accrual-basis treatment within the same period, creating reconciliation nightmares.
- Failing to record accounts receivable for invoices issued near period-end.
- Underestimating the bookkeeping burden — accrual typically requires monthly close discipline that cash basis avoids.
Frequently asked questions
When is accrual accounting required?
Required for U.S. GAAP, public companies, businesses with inventory (with small-business exceptions), C-corps over $30M average revenue, and most audited financial statements. Many lenders and investors also require accrual books.
What's the difference between accrual and modified accrual?
Modified accrual (used by governments) recognizes revenue when measurable and available, and expenditures when liability is incurred — with some exceptions. Standard accrual (used by businesses) recognizes both when earned/incurred regardless of cash timing.
Can a small business voluntarily use accrual?
Yes — many small businesses use accrual even when not required, especially if they want a truer view of monthly profitability, plan to seek financing, or carry significant receivables/payables.
How do I switch from cash to accrual?
File IRS Form 3115 (Application for Change in Accounting Method) and adjust prior-period numbers. Most businesses do this with help from a CPA because the conversion involves multiple balance-sheet adjustments.
Why do investors prefer accrual financial statements?
Accrual better matches revenue to the period when value was created and expenses to the period they generated, giving a clearer picture of operational performance and trend over time. Cash-basis statements can be artificially smoothed or distorted by payment timing.
