An accrued cost is an expense your business has already incurred but hasn’t yet paid or been billed for by the end of an accounting period. You record it with an adjusting journal entry that debits an expense account and credits a liability account, so the obligation shows up on your books before any cash leaves. This is the backbone of accrual accounting, where transactions hit the ledger when they happen, not when payment clears.
What Makes a Cost “Accrued”
The defining feature is timing. Your company has consumed a resource or benefited from a service, but no invoice has arrived and no check has been written. The economic event already occurred. The vendor just hasn’t billed you yet, or the payment date hasn’t come around.
This comes from the expense recognition principle. Under generally accepted accounting principles, expenses land in the same period as the revenue they helped produce, regardless of when cash changes hands. If a contractor finishes a project for you in March but doesn’t send a bill until April, the cost belongs in March because that’s when the work supported your operations. Skipping the entry would inflate March’s profits and deflate April’s, which misleads anyone reading your financials.
Once recorded, the accrued cost sits on your balance sheet as a current liability. It represents money you owe in the near term for something you’ve already received.
Common Examples
Accrued costs show up anywhere there is a gap between consuming a resource and paying for it. A few appear in nearly every company’s books.
- Wages and salaries. If your pay period ends on the 15th but the accounting month closes on the 30th, employees have earned roughly two weeks of pay that hasn’t been disbursed. That unpaid compensation is an accrued cost until payday.
- Interest on debt. A loan may charge interest quarterly, but the cost accrues daily. At month-end you record the interest that has built up since the last payment, even if the lender won’t bill you for another two months.
- Utilities. Your electricity runs all month, but the power company’s billing cycle rarely lines up with your accounting period. You estimate the last few days of usage and record that amount so the full month’s cost appears in the right period.
- Property taxes. Many jurisdictions assess property taxes once or twice a year, yet the obligation accrues over the entire period the property is used. Businesses typically spread the annual bill across each month so no single period absorbs a disproportionate hit.
- Professional services. An auditor or law firm may work for weeks before sending a bill. The hours they’ve logged are an expense you’ve consumed, invoice or not.
How to Record an Accrued Cost
Recording an accrual takes a two-line adjusting journal entry on the last day of the accounting period. One line increases an expense on your income statement; the other creates a liability on your balance sheet.
The Accrual Entry
Suppose your employees have earned $8,000 in wages between the last payday and month-end. You haven’t cut checks yet, but the work is done. The entry looks like this:
- Debit: Wages Expense — $8,000
- Credit: Accrued Wages Payable — $8,000
The debit pushes $8,000 of labor cost onto this month’s income statement. The credit creates an $8,000 current liability showing you owe that money. Your financial statements now reflect reality: you consumed $8,000 of labor this period, and you still owe it.
The Payment Entry
When you actually pay those wages in the next period, you clear the liability and reduce cash:
- Debit: Accrued Wages Payable — $8,000
- Credit: Cash — $8,000
The liability disappears because the obligation is settled. No additional expense hits the new period’s income statement, because the cost was already recognized in the prior month where it belonged.
When the Estimate Turns Out Wrong
Accrued costs are estimates, and estimates are sometimes off. If you accrued $8,000 in wages but the actual payroll comes to $8,300, you record the extra $300 as an expense in the new period when you learn the true amount. Small variances like this are routine and don’t require restating the prior period’s financials. Where the difference is large enough to mislead someone reading the statements, the correction may need more formal treatment depending on your company’s materiality thresholds.
Reversing Entries
Many accounting teams post a reversing entry on the first day of the new period. This entry is the mirror image of the original accrual: it debits the liability and credits the expense for the same amount. The purpose is mechanical. Without it, whoever processes the actual payment has to remember that part of the expense was already recorded last period and split the payment entry accordingly. That kind of manual tracking invites mistakes, especially when different people handle accruals and payment processing.
With a reversing entry in place, the payment can be recorded normally as a full expense, and the reversal automatically offsets the portion already recognized. The net effect is the same, but the process is simpler and less prone to double-counting. Most modern accounting software can automate reversals, which removes the human-error risk almost entirely.
Accrued Costs Versus Accounts Payable
Both accrued costs and accounts payable are current liabilities, but they differ in one practical way: whether you have an invoice. Accounts payable means a vendor has sent you a formal bill with a specific dollar amount. You know exactly what you owe and to whom. An accrued cost is your internal estimate of an obligation where no bill has arrived yet.
This distinction matters for controls. Paying an accounts payable item involves matching the invoice against a purchase order and a receiving report, a three-way check most companies treat as standard procedure. Paying against an accrual involves comparing your original estimate to the invoice that eventually shows up and reconciling any difference. The documentation trail is thinner, which is why accruals deserve extra scrutiny at close. Getting a quick estimate directly from the vendor is often the most reliable method when the dollar amount is significant.
Accrued Costs Versus Prepaid Expenses
Accrued costs and prepaid expenses are opposite timing mismatches. An accrued cost means you consumed first and will pay later. A prepaid expense means you paid first and will consume later. They sit on opposite sides of the balance sheet: accrued costs are liabilities, while prepaid expenses are assets.
If you pay six months of insurance premiums upfront in January, that payment is a prepaid expense. Each month you use up one-sixth of it, moving that portion from the asset column into insurance expense. If instead your insurance company bills you after coverage ends, the monthly cost you haven’t yet been billed for is an accrued expense. Both adjustments serve the same goal: putting the expense in the period it actually relates to.
How Accrued Costs Affect Financial Statements
Failing to record accrued costs makes your numbers look better than they are in the short term and worse in the next period.
On the income statement, skipping an accrual understates expenses for the current period, which overstates net income. Anyone evaluating profitability, whether an investor, a lender, or your own management team, would be working with inflated figures. When the bill finally arrives the next period, that period absorbs the full hit, creating artificial volatility between periods.
On the balance sheet, unrecorded accruals understate current liabilities. Because the current ratio divides current assets by current liabilities, missing accruals make the ratio look healthier than it really is. A lender checking your liquidity position before extending credit would get a misleading picture. Recording accruals properly increases the denominator of that ratio and reflects the true short-term obligations your business faces.
Tax Rules for Accrued Costs
For financial reporting, the expense recognition principle controls when an accrued cost appears on your income statement. For tax purposes, the rules are stricter and come with deadlines that can shift a deduction by a full year if you miss them.
Who Has to Use Accrual Accounting
Not every business gets to choose. C corporations and partnerships with a corporate partner generally must use the accrual method unless they meet a gross receipts test. For 2026, a business qualifies for the simpler cash method if its average annual gross receipts over the prior three tax years don’t exceed $32 million. Businesses above that threshold must use accrual accounting and follow the tax rules below.1Office of the Law Revision Counsel. 26 USC 448 – Limitation on Use of Cash Method of Accounting
The All Events Test and Economic Performance
Under federal tax law, an accrual-method business can deduct an expense only when three conditions are met: all events have occurred that establish the liability, the amount can be determined with reasonable accuracy, and economic performance has taken place.2Internal Revenue Service. IRS Publication 538 – Accounting Periods and Methods Economic performance generally means the service was provided to you, the property was delivered, or you actually used the asset. If a vendor performs consulting work for you in November, economic performance occurs in November as the work is done, and that’s when the deduction becomes available.3Office of the Law Revision Counsel. 26 USC 461 – General Rule for Taxable Year of Deduction
The 2½-Month Rule for Wages and Bonuses
Employee compensation has its own carve-out. If you accrue wages, bonuses, or vacation pay at year-end, you can deduct them on that year’s tax return as long as payment reaches the employee within 2½ months after the close of the tax year. For a calendar-year business, that deadline is March 15. Miss it, and the deduction shifts to the year you actually pay.2Internal Revenue Service. IRS Publication 538 – Accounting Periods and Methods This is one of the most commonly used year-end tax planning strategies, but it requires the liability to be fixed and determinable before December 31. A vague promise to “probably pay bonuses” doesn’t qualify.
One trap catches business owners regularly. If the recipient is a shareholder of an S corporation or a majority owner of a C corporation, the deduction is automatically deferred until the year the recipient actually receives the cash, regardless of when you accrued it.
Recurring Item Exception
For recurring expenses where economic performance hasn’t technically occurred by year-end, the tax code offers a limited workaround. You can still deduct the expense in the current year if the all events test is met, economic performance occurs within 8½ months after year-end, the item is recurring, and it’s either immaterial or accruing it produces a better match against income.3Office of the Law Revision Counsel. 26 USC 461 – General Rule for Taxable Year of Deduction Utility bills and recurring service contracts are the classic candidates.
When an Accrual Isn’t Worth the Effort
Not every unpaid cost at period-end warrants a journal entry. If your company spends $50 on office supplies that arrive on December 30 without a bill, nobody expects you to accrue it. Materiality draws the line: an omission matters only if it would change a reasonable person’s decision when reading the financial statements.
Most companies set a dollar threshold below which accruals aren’t required. The specific number depends on the size of the business. A company with $2 million in revenue might set the bar at $500; a company with $200 million might ignore accruals under $10,000. Above the threshold, the practical routine is to review open purchase orders at month-end for goods or services received but not yet billed, check invoices that arrive in the first few days of the new period to see if they belong to the prior period, and confirm estimated amounts with vendors when the numbers are large. A sloppy close means accruals get missed or recycled from prior months without adjustment, and both problems erode the accuracy that accrual accounting is supposed to provide.
