Accruals and prepaids are the same idea seen from opposite sides: both fix the gap between when cash moves and when the expense actually belongs. A prepaid is cash you paid before you got the benefit, so it sits on the balance sheet as an asset. An accrual is an expense you have already incurred but not yet paid, so it sits there as a liability. Get both right at month end and your profit and loss statement shows what really happened, not just what cleared the bank.
This guide walks through the definitions, the journal entries, an amortization schedule, a month-end routine and the mistakes we see most often when we clean up books.
TL;DR
- Prepaids are assets. You paid first and receive the benefit later, so you record the payment on the balance sheet and expense it over the period it covers.
- Accruals are liabilities. You received the benefit first and pay later, so you record the expense now and the obligation until you pay.
- Both are adjusting entries. They exist so each expense lands in the period it belongs to, which is the point of accrual-basis accounting.
- Reverse accruals automatically. Set the reversal for the first day of the next period so the real invoice does not double count the expense.
- Set a materiality line. Not every small item deserves an entry, but the threshold should be written down and applied consistently.

The core difference: timing of cash versus timing of benefit
The cleanest way to keep these straight is to ask which came first, the cash or the benefit.
- Cash first, benefit later: prepaid expense (an asset).
- Benefit first, cash later: accrued expense (a liability).
A standard finance textbook frames it the same way: accruals cover expenses incurred but not yet paid, a liability, while prepaids are payments made for goods or services not yet received or consumed, an asset. Both are corrections to the raw cash record, and both are what separates accrual accounting from simply watching the bank balance.
The mirror-image idea applies to revenue. Accrued revenue is income you have earned but not billed; deferred revenue is cash a customer paid before you delivered. If you sell subscriptions or multi-month contracts, our guide to deferred revenue accounting, entries and ASC 606 covers that side in detail.
| Prepaid expense | Accrued expense | |
|---|---|---|
| What happened | You paid before receiving the benefit | You received the benefit before paying |
| Balance sheet | Current asset | Current liability |
| Income statement effect | Expense recognized gradually as the benefit is used | Expense recognized now, in the period incurred |
| Typical examples | Annual insurance, software licenses, rent paid ahead, retainers | Wages earned but unpaid, utilities, interest, services received but not invoiced |
| Entry at month end | Debit expense, credit prepaid asset | Debit expense, credit accrued liabilities |
How prepaid expenses work
A prepaid expense occurs when you pay in advance for something you will receive later. Under standard treatment these payments are carried as assets until the benefit is realized. Universities that publish close guidance for their staff say the same thing: a prepaid is held on the balance sheet as an asset until the goods or services are received. Ohio University's finance office frames the year-end problem plainly: a cost paid in one fiscal year for goods or services that arrive in a later one is a prepaid, not an expense of the year it was paid.
Common prepaids for a small or midsize business:
- Annual or semiannual insurance premiums
- Software and SaaS subscriptions paid yearly
- Rent paid in advance
- Trade show registrations for a future event
- Deposits on services and annual maintenance contracts
- Retainers paid to professional firms
Prepaid journal entries
Take a hypothetical example. On January 1 you pay $12,000 for a 12-month insurance policy.
Step 1, when you pay:
| Account | Debit | Credit |
|---|---|---|
| Prepaid insurance | $12,000 | |
| Cash | $12,000 |
Nothing hits the income statement yet. You swapped one asset (cash) for another (prepaid insurance).
Step 2, each month-end for twelve months:
| Account | Debit | Credit |
|---|---|---|
| Insurance expense | $1,000 | |
| Prepaid insurance | $1,000 |
After three months, the prepaid balance is $9,000 and $3,000 of expense has hit your P&L. By December 31 the balance is zero.
A prepaid amortization schedule
For anything that runs longer than a few months, keep a schedule rather than recomputing each close. A simple one has one row per prepaid item and these columns:
- Vendor and description
- Payment date and amount
- Coverage start and end dates
- Monthly expense (amount divided by months covered)
- Expense recognized to date
- Remaining balance
- Expense account and balance sheet account
Here is the insurance example above for the first quarter:
| Month | Opening balance | Amortization | Closing balance |
|---|---|---|---|
| January | $12,000 | $1,000 | $11,000 |
| February | $11,000 | $1,000 | $10,000 |
| March | $10,000 | $1,000 | $9,000 |
The closing balance on the schedule must equal the prepaid balance in your general ledger. If it does not, something was posted outside the schedule. That tie-out is part of any good accounts reconciliation routine.
Do all prepaids need to be capitalized?
No. Many companies expense small prepayments immediately because tracking them costs more than the accuracy gains. The key is a written policy, say a dollar threshold and a minimum coverage period, applied the same way every month. For tax treatment, check the rules that apply to you with your tax professional. Rules differ by country, and the Canada Revenue Agency's guidance on prepaid expenses, for example, says to claim a prepaid expense in the years you get the benefit under the accrual method. That is a Canadian rule, not a U.S. one.
How accrued expenses work
An accrual records an expense that was incurred in one period but not paid until a later one. The University of Washington's instructions say the same in plain terms: an accrual journal entry records expenses incurred during a period but not yet paid, so the financial statements reflect the true position.
Why does this matter? Under U.S. GAAP, institutions such as Columbia University note that financial statements must be presented on the accrual basis, because it gives a more accurate picture than cash movements. If your lender, investor or auditor expects GAAP statements, accruals are not optional.
Typical accruals:
- Wages and payroll taxes earned in the last days of the month but paid next month
- Bonuses and commissions earned but not yet paid
- Utilities used but not yet billed
- Professional fees for work performed but not yet invoiced
- Interest accrued on loans between payment dates
- Goods or services received where the vendor invoice has not arrived
Accrual journal entries
Hypothetical example: your team earned $18,000 in wages for the last four working days of March, payable on April 3.
March 31, the accrual:
| Account | Debit | Credit |
|---|---|---|
| Wages expense | $18,000 | |
| Accrued wages payable | $18,000 |
April 1, the reversal (automatic):
| Account | Debit | Credit |
|---|---|---|
| Accrued wages payable | $18,000 | |
| Wages expense | $18,000 |
April 3, payroll runs normally: the full amount is expensed through the regular payroll entry. The reversal cancels the March accrual so April does not carry the cost twice, and March carries the cost it earned.
The University of Colorado's controller recommends exactly this approach: select a reversal date at the start of the next period so the invoice or payment, once processed, does not duplicate the expense.
Accrual versus accounts payable
This is where beginners get stuck. An accounts payable entry exists because you have an invoice. An accrual exists because you know the cost is real but you have no invoice yet. UC Merced puts it this way: accruals differ from standard payables because they are recorded before an invoice is on hand. When the invoice finally arrives, it goes through payables, and your reversing entry clears the estimate.
A month-end routine for accruals and prepaids
Here is a checklist you can run each close. It works in QuickBooks, Xero or a spreadsheet-fed ledger.
- Roll the prepaid schedule. Post the month's amortization for every active item and confirm the closing balance equals the general ledger.
- Add new prepaids. Review the month's payments for annual or multi-month items that were coded straight to expense.
- List unrecorded costs. Ask each department head what was received or performed this month without an invoice. Check open purchase orders and contracts too.
- Estimate payroll accruals. Calculate wages, taxes, PTO and bonuses earned through the last day of the month.
- Book the accruals with a reversal date. Use the first day of next month and label the entries clearly. The University of Washington's guidance, for example, shows a naming prefix such as ACC for accruals and an adjusting label for entries made after close.
- Attach support. Keep the calculation, contract or email that justifies each entry.
- Review last month's accruals. Compare estimates to the actual invoices that arrived and note large variances so next month's estimates improve.
- Reconcile and review. Tie out every prepaid and accrued liability account to its support, then read the P&L for anything that looks too low or too high.
This routine is also a core part of closing entries and period-end checks, and skipping it is the usual reason a month's margin turns out to be fiction.
Setting a materiality threshold
You do not need an accrual for every $40 invoice. Larger institutions publish their cutoffs. Columbia's year-end guidance, for instance, sets a materiality threshold of $25,000 per invoice for certain accrual journals. That is a large university's policy, not a rule for your business. A ten-person company might choose $500 or $1,000. Pick a number, write it into your close procedures, and apply it every month so results stay comparable.
Why investors and auditors look closely at these accounts
Prepaids and accruals reveal how well you track what you owe and what you have consumed. Commentary on prepaid expenses notes that investors and auditors pay attention to how these accounts are managed as a signal of internal control. A prepaid balance that never shrinks suggests nobody is amortizing. An accrued liabilities line that is suspiciously flat suggests nobody is accruing.
The same discipline applies on the revenue side. If you report recurring revenue, judgment matters as much as automation, a point explored in this piece on defensible revenue reporting. Whatever tools you use, someone has to decide what belongs in each period and be able to explain why.
Perspective: what we see in client books
When we take over a set of books, the accrual and prepaid accounts tell us quickly how the business has been run. We see three patterns again and again.
First, annual payments coded straight to expense. A $9,000 software renewal hits January and makes January look terrible and the other eleven months look great. Owners then make hiring or pricing decisions on a distorted trend.
Second, prepaid balances that sit untouched for a year because nobody built a schedule. The balance sheet carries an asset that has long since been used up.
Third, no accruals at all because the books are run on a cash basis by habit. That is fine for some small businesses, but it stops being fine when a lender, a board or a buyer wants accrual statements. If you are weighing the move, our notes on choosing the right accounting method and transitioning to accrual accounting cover the trade-offs.
Our advice is simple: keep the process boring. A schedule, a checklist, a written threshold and a reviewer who is not the preparer. Fancy software does not fix missing judgment, and judgment is cheap when the routine is consistent. We also tailor the level of detail to the business, because a ten-person firm does not need the controls of a hospital system, and a nonprofit tracking grant periods has needs a retailer does not.

Common mistakes and how to avoid them
Double counting after an accrual. The accrual is booked, the invoice arrives, and both stay in the expense account. Fix: use auto-reversing entries and check the reversal posted.
Treating a prepaid as an expense because it was easy. Fix: review every payment above your threshold for coverage dates before coding it.
Estimating without support. An accrual of a round number with no calculation will not survive review. Keep the contract, timesheet or usage record.
Forgetting year-end cutoff. Fiscal year-end is where errors become visible, because the unrecorded costs of the old year spill into the new one. A cutoff review of the first few weeks of invoices after year-end catches most of them.
Letting estimates drift. If last month's accrual for utilities was $2,400 and the bill came in at $3,100, adjust your method. Repeated large variances are a sign of a weak process.
Mixing up payroll accruals. Wages, employer taxes, PTO and bonuses each accrue differently. If payroll is outsourced, get the register by pay period, not only by check date.
Unusual or unexplained entries in these accounts can also signal a deeper problem, such as manipulated expenses. Our guide to stopping accounts payable fraud shows the small-team controls that help, and when something already looks wrong, forensic accounting is the next step.

FAQ
What is the difference between accruals and prepaids?
Timing. A prepaid is cash paid before you receive the benefit, so it is an asset that you expense over time. An accrual is an expense you have incurred but not paid, so it is a liability. Both adjust your books so costs land in the period they belong to.
Are prepaids an asset or a liability?
Prepaids are current assets. You have paid for a future benefit, and the balance falls as you use that benefit. The related liability appears only if you still owe money, which is an accrual or a payable.
Should prepaids be accrued?
Not in the usual sense. A prepaid has already been paid, so it is amortized, not accrued. You accrue costs that are unpaid. The one overlap is when a prepaid contract runs past the payment and a further charge is incurred but not yet billed. That extra amount is a separate accrual.
How are prepaid expenses treated under accrual accounting?
They are recorded as an asset when paid, then moved to expense on a regular schedule, usually monthly, across the coverage period. The expense matches the period in which you used the benefit, regardless of when the cash left your account.
Do I need to reverse accruals?
In most cases yes. Reversing the accrual on the first day of the next period clears the estimate, so when the actual invoice or payroll posts, the expense is not counted twice.
