What Is Accrual Accounting? Complete Guide for 2026
Accrual accounting is the method that records revenue when it's earned and expenses when they're incurred — not when cash moves. It's the standard required by US GAAP, and the only method that produces financial statements investors, lenders, and auditors will trust.
Accrual accounting is a method that records revenue when it is earned and expenses when they are incurred, regardless of when cash changes hands. It is the method required by US Generally Accepted Accounting Principles (GAAP) and by the IRS for most businesses with gross receipts above the indexed Section 448(c) threshold (~$30 million in 2026).
The opposite method is cash accounting, which records revenue and expenses only when cash moves. Accrual produces a truer picture of performance; cash is simpler but misleading once a business takes on contracts, prepayments, or inventory.
Key Takeaways
- Accrual accounting records revenue when earned and expenses when incurred. Cash basis records them only when cash moves.
- US GAAP requires accrual. Publicly traded companies must use it. Most private companies above $30M (indexed) in gross receipts must use it for tax purposes.
- The two principles behind accrual: revenue recognition (record revenue when earned) and matching (record expenses in the period that produced the revenue).
- The five accrual categories most businesses encounter: accrued revenue, accrued expenses, deferred revenue, prepaid expenses, and depreciation.
- Every accrual journal entry needs a reversing entry the following period — the step most blogs forget.
- "Accrual" and "accrued" refer to different things: accrual is the method; accrued items are specific entries (accrued revenue, accrued expenses).
What Accrual Accounting Actually Means
Cash accounting records what your bank balance reflects: money in, money out. Accrual accounting records what your business actually did: services performed, costs incurred, obligations created, value owed.
Accrual accounting is the recognition method that records revenue in the period the underlying work is performed, and expenses in the period the underlying cost is incurred — independent of when cash moves between parties.
The simplest way to see the difference: imagine you deliver $10,000 of consulting work in March and invoice the client, but the client pays in May.
- Cash accounting records $10,000 of revenue in May, when the cash arrives. March looks unprofitable; May looks great.
- Accrual accounting records $10,000 of revenue in March, when the work was performed. May shows the cash receipt clearing the receivable.
March is the period that produced the value. Accrual puts the revenue there.
The Two Principles That Drive Accrual Accounting
1. The revenue recognition principle
Revenue is recognized in the period it is earned — the period in which the seller's performance obligation to the customer is satisfied — not necessarily when cash is collected. Under ASC 606, this is operationalized through a five-step model that walks from contract identification to revenue recognition. For most companies, the practical result is: deliver the goods or services, then recognize the revenue.
2. The matching principle
Expenses are recognized in the same period as the revenue they helped generate. If you pay your sales commission to the rep who closed the March contract, that commission expense belongs in March — even if you write the check in April.
Together, these two principles produce financial statements where every period's income reflects what actually happened that period — not what cleared the bank.
A Real Example: Same Transaction, Two Methods
A SaaS company signs a $36,000 annual contract on January 1 and collects the full amount upfront. Under each method, here's what shows up on the income statement.
| Month | Cash basis revenue | Accrual basis revenue |
|---|---|---|
| January | $36,000 | $3,000 |
| February | $0 | $3,000 |
| March – December | $0 each | $3,000 each |
| Full year | $36,000 | $36,000 |
Both methods report the same annual total. But cash basis shows all $36K in January (when no service had yet been provided) and zero for the next eleven months. Accrual basis distributes the $36K across the twelve months in which the service is delivered. Cash basis lies about which months were productive. Accrual basis tells the truth.
On the balance sheet, the difference is mirrored: under accrual, $33,000 sits in deferred revenue at the end of January — a liability representing the obligation to deliver eleven more months of service. Under cash basis, deferred revenue doesn't exist.
The Five Accrual Categories Every Business Encounters
| Category | What it captures | Where it lives |
|---|---|---|
| Accrued revenue (a.k.a. unbilled revenue) | Work performed, not yet invoiced | Asset (contract asset) |
| Accrued expenses | Costs incurred, not yet billed/paid | Liability |
| Deferred revenue | Cash collected for work not yet delivered | Liability |
| Prepaid expenses | Cash paid for items consumed over time | Asset |
| Depreciation | Cost of long-lived assets spread over their useful life | Income statement (offset to fixed assets) |
Every accrual-basis business sees these five categories in some combination. SaaS companies live mostly in deferred revenue and prepaid expenses. Services firms accumulate accrued and unbilled revenue. Manufacturers carry inventory, prepaid expenses, and depreciation. The category mix tells you a lot about the business model.
Accrual Journal Entries (with the Reversal Step Most Blogs Forget)
Scenario: A contractor delivers $5,000 of work to your business in December. The invoice arrives January 15 and is paid January 30. Under accrual, the expense belongs in December.
December 31 — Accrue the expense
| Date | Account | Debit | Credit |
|---|---|---|---|
| 12/31 | Contractor Expense | $5,000 | |
| Accrued Liabilities | $5,000 |
January 1 — Reverse the accrual
| Date | Account | Debit | Credit |
|---|---|---|---|
| 01/01 | Accrued Liabilities | $5,000 | |
| Contractor Expense | $5,000 |
January 30 — Record the actual payment
| Date | Account | Debit | Credit |
|---|---|---|---|
| 01/30 | Contractor Expense | $5,000 | |
| Cash | $5,000 |
The January 1 reversal is the step most accrual guides skip. Without it, January would double-count the $5,000 — once from the reversed accrual hitting expense, once from the actual payment. QuickBooks supports automatic reversal with a checkbox on the journal entry screen; use it for every accrual-and-pay cycle.
"Accrual" vs. "Accrued" — Terminology Most Blogs Confuse
Accrual is the method — the entire framework of recognizing revenue and expenses when earned/incurred. Accrued refers to specific entries under that method: accrued revenue (work done, not invoiced), accrued expenses (cost incurred, not billed), accrued liabilities (a broader bucket including accrued expenses, accrued payroll, and other unbilled obligations).
Accrual is the system; accrued items are the entries you make inside it.
"Accrual basis isn't optional once you're past the smallest scale. Investors won't trust cash-basis books. Lenders won't underwrite on them. Auditors will require restatement. The earlier a business switches, the less restatement work later. The right time to set up accrual is before you have to." — Tom Zehentner, CPA · Senior Controller, FinOptimal
Who Has to Use Accrual Accounting?
- Publicly traded companies — required by SEC rules, which require US GAAP, which requires accrual.
- Most private companies above the IRS Section 448(c) threshold — gross receipts above ~$30M (indexed annually) generally requires accrual for tax purposes.
- C corporations — generally required to use accrual regardless of size, with some small-business exceptions.
- Companies with inventory — historically had to use accrual; exceptions exist for small businesses under the gross receipts threshold.
- Companies seeking outside capital — VCs, PE, lenders, and acquirers will demand accrual-basis statements, regardless of IRS requirements.

What Accrual Accounting Reveals That Cash Basis Hides
- True profitability by period. Cash basis spikes in collection months and dips in payment months — even when the business performance is stable.
- Obligations to customers. Deferred revenue exists only on accrual books. Without it, prepaid contracts look like pure profit.
- Outstanding receivables. Accounts receivable is an accrual concept. Cash basis pretends every dollar invoiced is already in hand.
- Earned but uncollected revenue. Unbilled revenue is an asset accrual recognizes. Cash basis ignores work done but not yet invoiced.
- True cost of operations. Matching the cost of goods sold to the revenue they generated reveals real gross margin.
This is what we call the "Profitability Illusion": a cash-basis business can look very profitable in a month it collected on prior work, and very unprofitable in a month it paid down its accrued obligations — when the underlying business performance was flat throughout. Accrual breaks the illusion.
Common Mistakes When First Switching to Accrual
Flipping the reporting toggle without making the entries
QuickBooks Online has an accrual reporting toggle. Flipping it does not create the underlying journal entries. Without the entries, the toggle just reformats cash-basis data into accrual-looking reports. See our QBO accrual setup guide.
Forgetting the reversal step
Every accrual journal entry needs a reversal in the next period. Skipping the reversal double-counts the expense or revenue.
Mixing the conversion year's books
The first year of conversion needs an opening balance restatement to reflect accrued items at the conversion date. Skipping the restatement makes year one look anomalous and triggers questions during audits or due diligence.
Missing the IRS Form 3115 filing
Switching from cash to accrual for tax purposes generally requires filing Form 3115 (Application for Change in Accounting Method). The form has a Section 481(a) adjustment that smooths the conversion's tax impact over four years.
Treating accrual as just a bookkeeping change
Accrual changes which periods look profitable. It changes the working capital picture. It changes what investors see. Treating it as a back-office task underestimates how much it changes the business's financial narrative.
Frequently Asked Questions
What is accrual accounting in simple terms?
Accrual accounting records revenue when you earn it (deliver the goods or services) and expenses when you incur them (use the goods or services) — not when cash actually changes hands. It produces a more accurate picture of how a business performed in any given period.
What is the difference between cash and accrual accounting?
Cash accounting recognizes revenue and expenses only when cash moves. Accrual accounting recognizes them when the underlying economic activity occurs. The same business will report different numbers under each method in any given month, though annual totals usually converge.
Is accrual accounting required by GAAP?
Yes. US Generally Accepted Accounting Principles (GAAP) require accrual basis. Cash-basis financial statements are not GAAP-compliant and won't be accepted by public investors, most lenders, or auditors.
When does the IRS require accrual accounting?
Generally, when a business's average annual gross receipts exceed the Section 448(c) threshold (~$30M in 2026, indexed annually for inflation). C corporations are typically required to use accrual regardless of size, with limited small-business exceptions.
What are the disadvantages of accrual accounting?
It's more complex than cash basis: it requires accrual entries every period, reversals the following period, and the discipline of a structured month-end close. It also requires tracking accounts receivable, accounts payable, deferred revenue, and prepaid expenses — none of which exist under cash basis.
Can a small business use accrual accounting?
Yes. Any business can elect accrual basis regardless of size. Many small businesses choose accrual voluntarily to produce statements that hold up to investor and lender scrutiny — even when the IRS doesn't require it.
How do I switch from cash to accrual accounting?
The process: restate opening balances to reflect accrued items at the conversion date, set up the necessary balance sheet accounts (deferred revenue, prepaid expenses, accrued liabilities), file IRS Form 3115 for the change in accounting method, and run the first accrual close. Working with a CPA is strongly recommended.
Does QuickBooks Online support accrual accounting?
Yes — accrual is the recommended setting. But QBO doesn't automate the underlying journal entries (deferred revenue recognition, prepaid amortization, accrued liabilities). Those still require manual entries or a connected automation tool. See our QBO accrual setup guide.
