Accrued expenses: recognizing costs before the bill arrives
What an accrued expense is, the entry and its reversal, and an honest look at when accruals matter at small scale — and when they are more ceremony than information.
An accrued expense puts a cost into the month that consumed it, even though the bill has not arrived. December's contractor hours belong on December's P&L whether the invoice shows up January 3rd or February 9th. The mechanism is a two-line entry at close and its mirror-image reversal the next morning — and the honest question at small scale is not how (it is easy) but when it is worth doing at all.
The entry and its mirror
| Account | Debit | Credit |
|---|---|---|
| Contract labor expense | 3,600.00 | |
| Accrued expenses payable | 3,600.00 |
Estimate from timesheets or the agreement. A close estimate in the right month beats a perfect number in the wrong one.
| Account | Debit | Credit |
|---|---|---|
| Accrued expenses payable | 3,600.00 | |
| Contract labor expense | 3,600.00 |
When the invoice arrives and is entered normally in June, it nets against this credit. If it arrives at 3,750.00, June shows only the 150.00 estimate difference — self-correcting.
The reversal is the whole trick. Without it, whoever enters the June invoice must remember the accrual and skip or reduce the entry — a memory-based control, which is to say, not a control. Full mechanics across all the entry families are in the adjusting entries guide.
When accruals matter at small scale — and when they don't
Accrual is a materiality decision. Ask what the statement reader would conclude with and without the entry.
A practical accrue-or-skip test:
| Situation | Accrue? | Why |
|---|---|---|
| Recurring monthly utility, ~400.00, bill lags a week | Skip | Every month absorbs roughly one bill anyway; no distortion |
| One-time project invoice, 15,000.00, arrives next month | Accrue | Omitting it overstates the month's profit materially |
| Payroll period straddling month-end | Accrue if bonuses/margins are measured monthly | Wage timing can swing a small P&L noticeably |
| Interest on a loan, payment due the 10th | Accrue at year-end; optional monthly | Year-end matters for the accountant and the return |
| December costs, any material size, calendar-year accrual-basis taxpayer | Accrue | Year-end cutoff determines the tax year of the deduction |
Two situations force rigor regardless of taste. First, year-end: for an accrual-basis taxpayer, whether a cost lands in December or January changes the tax year of the deduction under the all-events and economic-performance rules of Section 461 — see Publication 538. Second, anything you measure monthly — margins, bonuses, covenant ratios — because a lumpy unaccrued cost makes two months lie in opposite directions.
Keeping the account honest
The accrued liabilities balance should contain only current, nameable items — this month's accruals awaiting their bills. Review it at every close (step 6 of the month-end close checklist): a stale accrual that never reversed, or a reversal that posted without its accrual, shows up here first. An accrued balance nobody can itemize is a cousin of the junk-drawer problem described in suspense account usage.
Frequently asked questions
- What is an accrued expense?
- An accrued expense is a cost the business has already incurred — utilities used, contractor hours worked, interest run up — for which no bill has been received or recorded by period-end. The accrual entry debits the expense and credits an accrued liabilities account, so the month that consumed the cost is the month that reports it.
- Do I need to accrue expenses in a small business?
- Only if the amounts are large enough to change what your statements say. A recurring 400.00 utility bill that arrives every month shifts each month's P&L trivially; skipping the accrual is defensible. A 15,000.00 project invoice arriving a month after the work is not — accrue anything that would visibly distort a month or a year-end.
- How does an accrual reversal work?
- The reversal posts the exact opposite entry on the first day of the next period — debit the accrued liability, credit the expense. When the real bill is then entered normally, it nets against the reversal, leaving the expense in the original month and nothing double-counted. Set accruals to auto-reverse so no one has to remember.
