Accrued expenses are costs your business has already incurred but hasn’t yet paid or been invoiced for, and under the accrual method of accounting you record them in the period the underlying service or benefit was consumed rather than when cash moves. That timing rule comes from the matching principle in Generally Accepted Accounting Principles: expenses belong in the same period as the revenue they helped generate. If your employees work the last week of December but aren’t paid until January, that labor cost belongs on December’s books. Skip the entry and December’s profit looks better than it was, January’s looks worse, and anyone making decisions from those statements is working with distorted numbers.
The categories are familiar once you know what you’re looking for. Utilities used but not yet billed. Interest building on a loan between payment dates. Wages earned after the last paycheck of the period. Property taxes accumulating between semi-annual bills. Paid time off employees have earned but not taken. Each represents a real obligation that exists whether or not paperwork has caught up.
Accrued Expenses vs. Accounts Payable
Both sit in current liabilities on the balance sheet, but they aren’t the same thing, and the difference comes down to whether an invoice exists. Accounts payable is money you owe on a bill the vendor has already sent, with an exact amount and a due date. An accrued expense is an obligation that’s real but not yet invoiced, so the amount is typically an estimate built from contracts, historical usage, or rate calculations.
The trigger differs too. Accounts payable entries get posted when a vendor invoice arrives and is entered. Accrued expenses are posted through adjusting journal entries at period-end because time has passed or a service has been consumed. When the actual invoice eventually shows up, you adjust the accrued figure to match the real number. Underestimate the accrual and you understate liabilities; miss it entirely and you overstate profit.
Common Types of Accrued Expenses
Wages and Salaries
Payroll is the most common accrual because pay periods rarely line up with month-ends. Five employees earning $25 an hour who each worked 24 hours between the last paycheck and month-end produce $3,000 in labor cost that belongs in this period even though the checks won’t go out until next period. Depending on your accounting policy, you may also need to accrue the employer’s share of payroll taxes and benefits on those hours.
Interest on Loans
Loan interest accumulates daily even when your lender bills quarterly or annually. A $100,000 loan at 6% annual interest generates roughly $500 a month in interest cost, and each month-end close needs to capture that even when no payment is due.
Utilities and Services
Electricity, water, and internet run continuously, but the bill for December usage often doesn’t arrive until mid-January. Estimating the cost from recent bills or meter readings and booking it in December keeps the power that helped generate December revenue on December’s income statement.
Property Taxes
Property tax builds throughout the year even when your county collects once or twice annually. A $24,000 annual bill should accrue at $2,000 a month rather than landing as one lump when payment comes due, so your monthly operating cost reflects reality.
Vacation and Sick Leave
If employees earn paid time off that carries over, GAAP requires an accrued liability for those future absences. FASB ASC 710-10-25-1 lays out four conditions that all have to be met: the obligation stems from work already performed, the time vests or accumulates, payment is probable, and the amount can be reasonably estimated. Strict “use it or lose it” policies that prevent carryover generally take the accrual off the table because the time doesn’t accumulate. But if your actual practice is to pay out unused days regardless of what the handbook says, auditors will expect the accrual to match what really happens.
How to Calculate the Amount
Every accrual calculation starts with a firm cutoff date, usually the last day of the fiscal month or year, and works with data specific to the type of expense.
For wages, pull payroll records and count the hours worked between the last pay date and cutoff, then multiply by each employee’s rate. For loan interest on a simple-interest loan, daily interest is the principal times the annual rate divided by 365, multiplied by the days in your accrual period. For utilities, use the average of recent bills adjusted for seasonal patterns; a manufacturer running heavy December shifts shouldn’t base its estimate on a quiet August. For property taxes, divide the annual assessed amount by twelve. Vendor contracts spell out billing cycles and rates that let you compute a partial-period figure precisely.
Keep the spreadsheets, contracts, and vendor correspondence behind each figure. Auditors independently recalculate accruals, and clean support makes that testing far less painful.1Public Company Accounting Oversight Board. AS 1105 Audit Evidence
Booking the Journal Entry
Recording an accrual takes an adjusting journal entry that hits both the income statement and the balance sheet. You debit the relevant expense account and credit an accrued liabilities account.2Princeton University Finance and Treasury. Year-End Accruals For a $1,200 December electricity estimate:
- Debit Utility Expense $1,200
- Credit Accrued Liabilities $1,200
The entry has to be finalized before you close the period. December’s income statement now reflects the electricity cost, and December’s balance sheet shows the obligation.
Reversing the Entry
Most firms post a reversing entry on the first day of the next period that flips the accrual: debit Accrued Liabilities and credit Utility Expense for the same $1,200. Without the reversal, you’d end up expensing the electricity twice, once through the accrual and again when the actual bill runs through accounts payable. Modern accounting software will auto-post the reversal if you flag the original entry, which eliminates a common source of month-end error.
How Accruals Show Up on Financial Statements
Accrued expenses sit in the current liabilities section of the balance sheet because they’ll typically settle within 12 months, alongside accounts payable and short-term debt. Their size directly affects liquidity ratios. The current ratio (current assets divided by current liabilities) drops as accruals rise, and so does the quick ratio.
That matters for anyone with debt. Loan covenants often require minimum liquidity or ratio thresholds, and a large year-end accrual can technically push a healthy business out of compliance. If your loan agreement has financial maintenance covenants, model the impact of significant accruals before booking them.
Tax Rules: When You Can Actually Deduct an Accrued Expense
Booking an accrual on your books doesn’t automatically buy you a tax deduction in the same period. Federal tax law layers an extra requirement on top of GAAP’s matching principle: economic performance must occur before the expense is deductible.3Office of the Law Revision Counsel. 26 U.S. Code 461 – General Rule for Taxable Year of Deduction
When economic performance happens depends on the type of expense:
- For services provided to you, economic performance occurs as the other party actually performs the services. Consulting work contracted for but not yet started isn’t deductible even if accrued.
- For property provided to you, economic performance occurs as the property is delivered.
- For your use of someone else’s property, economic performance occurs as you use it, which is why rent accruals generally line up with deductibility.
- For workers’ compensation and tort liabilities, economic performance occurs only when you actually make the payment.
The result is that your books and your tax return can show different expense timing for the same transaction, and your accountant may need to track book-tax differences on accrued items you can’t yet deduct.
The 2.5-Month Rule for Bonuses
Accrued bonuses get special treatment. Compensation paid after the year it was earned is generally treated as deferred compensation and isn’t deductible until the employee includes it in income.4Office of the Law Revision Counsel. 26 U.S. Code 404 – Deduction for Contributions of an Employer Pay the bonus within two and a half months of tax year-end, though, and it’s not deferred compensation. For a calendar-year company, that means paying by March 15 to deduct the bonus in the year it was earned. Miss the window and the deduction shifts to the year of payment.
Who Has to Use the Accrual Method
Businesses that carry inventory generally have to use the accrual method for purchases and sales, but small business taxpayers can opt out.5Internal Revenue Service. Publication 538, Accounting Periods and Methods You qualify if your average annual gross receipts over the prior three tax years don’t exceed an inflation-adjusted threshold, set at $31 million for tax years beginning in 2025.6Internal Revenue Service. Revenue Procedure 2024-40 Businesses under that ceiling can generally use the cash method even with inventory.
Penalties for Getting the Timing Wrong
Misstating when an expense is recognized isn’t only an accounting problem. If it produces an underpayment of tax, the IRS can add a 20% accuracy-related penalty to the tax owed. The penalty applies when the understatement is “substantial,” which for individuals means more than 10% of the correct tax or $5,000, whichever is greater. For corporations other than S corps, the threshold is the lesser of 10% of the correct tax (or $10,000, if that’s more) and $10 million.7Internal Revenue Service. Accuracy-Related Penalty
Interest runs on unpaid penalties and compounds from the date the penalty applies. Negligence or intentional disregard of the rules can trigger the same 20% penalty independently of the dollar thresholds. Detailed calculations, supporting contracts, and a written rationale behind each estimate are the practical defense: an auditor who can follow how you arrived at a number and why it was reasonable has much less room to assess a penalty even when the estimate turns out to be slightly off.
