5.2 Correcting Current-Period Deferral Errors
Key Takeaways
- A prepaid recorded entirely as expense and never adjusted is corrected by debiting Prepaid and crediting Expense for the unexpired amount — $16,500 remaining on Cedar Street Bakery's $18,000 twelve-month policy paid December 1.
- A customer prepayment credited entirely to revenue and never adjusted is corrected by debiting Revenue and crediting Unearned Revenue for the unearned amount — $14,300 remaining on Riverton Storage's $15,600 retainer.
- Opposite original entries (a vendor prepayment debited to Accounts Payable; a customer deposit credited to Accounts Receivable) are reclassified to Prepaid or Unearned before any expired or earned slice is recognized.
- Asset-method and expense-method mix-ups are repaired by reversing the incompatible adjusting entry, then posting the adjusting entry that matches the original cash entry.
- After a deferral correction, prepaid or unearned must equal the unexpired or unearned dollars, and the income-statement account must equal the expired or earned dollars for the period.
Deferrals are the mirror of accruals: cash moved before the revenue was earned or the expense was incurred. AIPB's Mastering Correction of Accounting Errors materials include current-period deferral errors — prepaid items and unearned items recorded incorrectly, or recorded with a valid original entry and then never adjusted. This independent OpenExamPrep section treats four exam-frequent patterns: (1) a prepaid recorded as expense and never adjusted, (2) a customer prepayment recorded as revenue and never adjusted, (3) an original entry that used the opposite type of account, and (4) mixing the asset method with the expense method (or the liability method with the income method).
All of the corrections below assume the period is still open. The cash account is usually already correct; the repair reallocates between an income-statement account and a prepaid asset or unearned-liability account. Chapter 3 showed how to make these adjusting entries. This section shows how to repair them when the original cash entry, the adjusting entry, or both went wrong.
Two methods, one economic result
Bookkeepers may originally record a prepaid cost as an asset or as an expense. They may originally record a customer prepayment as a liability or as revenue. Either original method is acceptable if the period-end entry uses the matching method. Errors appear when the original method and the adjusting method do not match, or when the adjusting entry is skipped.
| Item | Asset / liability method original entry | Expense / income method original entry | Correct period-end idea |
|---|---|---|---|
| Prepaid insurance, rent, software | Debit Prepaid (asset), credit Cash | Debit Expense, credit Cash | Asset method: expense the expired slice. Expense method: set up remaining prepaid by reducing expense. |
| Customer prepayment for future service | Debit Cash, credit Unearned Revenue (liability) | Debit Cash, credit Revenue | Liability method: recognize the earned slice. Income method: set up remaining unearned by reducing revenue. |
The CB exam will not award points for "either method is fine" if the given facts show a method mix-up. Read the original debit and credit first, then ask what adjusting entry — if any — was posted.
Prepaid recorded as expense and never adjusted
On December 1, Cedar Street Bakery pays $18,000 for a 12-month insurance policy covering December 1 through November 30 of the next year. The bookkeeper debits Insurance Expense $18,000 and credits Cash $18,000 (expense method). No December 31 adjusting entry is made.
December's expired cost is 1/12 × $18,000 = $1,500. The remaining $16,500 is still a prepaid asset. Leaving the books as they are overstates insurance expense $16,500, understates Prepaid Insurance $16,500, and understates December net income $16,500.
Correcting entry dated December 31 (books open):
| Date | Account | Debit | Credit |
|---|---|---|---|
| Dec 31 | Prepaid Insurance | 16,500 | |
| Insurance Expense | 16,500 |
After the correction, expense is $1,500 and the balance sheet reports a $16,500 current asset. Cash stays at the $18,000 outflow already recorded. This is not an accrual: no payable is created.
If the original entry had used the asset method (debit Prepaid Insurance $18,000) and the bookkeeper never adjusted, the error runs the opposite direction: prepaid is still $18,000, expense is $0. The expired $1,500 must be recognized:
| Date | Account | Debit | Credit |
|---|---|---|---|
| Dec 31 | Insurance Expense | 1,500 | |
| Prepaid Insurance | 1,500 |
Exam trap: using the asset-method adjusting entry ($1,500 expense) after an expense-method original entry ($18,000 already in expense). That combination would put $19,500 in expense and a $1,500 credit balance in Prepaid Insurance. Always pair the correcting entry with the original method actually used.
Unearned recorded as revenue and never adjusted
On December 1, Riverton Storage collects $15,600 from a client for 12 months of locker service beginning December 1. The bookkeeper debits Cash $15,600 and credits Service Revenue $15,600 (income method). No adjusting entry is made at December 31.
December has earned 1/12 × $15,600 = $1,300. The remaining $14,300 is still unearned. Uncorrected, service revenue and net income are overstated $14,300, and Unearned Revenue (a liability) is understated $14,300. Cash is correct.
Correcting entry dated December 31:
| Date | Account | Debit | Credit |
|---|---|---|---|
| Dec 31 | Service Revenue | 14,300 | |
| Unearned Revenue | 14,300 |
If the original entry had used the liability method (credit Unearned Revenue $15,600) and no one adjusted, revenue would still be $0. The earned $1,300 would be recognized by debiting Unearned Revenue and crediting Service Revenue. Same ending balances; opposite correcting direction.
Leaving unearned receipts in revenue is the deferral error bankers notice first: cash came in, profit looks strong, and the obligation to perform next year is invisible on the balance sheet. Section 5.3 maps that financial-statement damage if the correcting entry never posts.
Opposite original-entry errors
"Opposite" means the original cash entry used the wrong class of account — typically a liability account for a prepaid asset, or a receivable account for unearned revenue. Cash may still be correct. The trial balance still balances. You find these by matching cash disbursements and cash receipts to contracts, not by hunting for an out-of-balance column.
Vendor prepayment posted to Accounts Payable. On December 1 Cedar Street prepays a supplier $7,200 for packaging to be delivered evenly over 12 months. The bookkeeper debits Accounts Payable $7,200 and credits Cash $7,200, as if paying down a trade balance. There was no related AP balance; the debit drives AP into a debit (negative) position, and no prepaid asset is established.
Reclassify while the period is open:
| Date | Account | Debit | Credit |
|---|---|---|---|
| Dec 31 | Prepaid Packaging | 7,200 | |
| Accounts Payable | 7,200 |
That restores AP and creates the asset. Then recognize December's expired 1/12 = $600:
| Date | Account | Debit | Credit |
|---|---|---|---|
| Dec 31 | Packaging Expense | 600 | |
| Prepaid Packaging | 600 |
If you skip the first reclassification and only debit expense, Accounts Payable remains wrong. Ending prepaid should be $6,600 ($7,200 − $600).
Customer deposit posted against Accounts Receivable. Riverton receives a $4,500 deposit on a January climate-controlled unit. The bookkeeper credits Accounts Receivable instead of Unearned Revenue. AR is understated $4,500 (or shows a credit balance), and the January performance obligation is missing from liabilities.
| Date | Account | Debit | Credit |
|---|---|---|---|
| Dec 31 | Accounts Receivable | 4,500 | |
| Unearned Revenue | 4,500 |
Do not debit Cash again. Cash was recorded when the deposit arrived. Do not credit Service Revenue: the storage month has not started.
Prepaid recorded as unearned (liability) instead of prepaid (asset). Cedar Street pays $9,600 for 12-month point-of-sale software with a debit to Unearned Revenue and a credit to Cash. That reduces a liability the bakery does not owe and still fails to record the prepaid asset. Correction: debit Prepaid Software $9,600, credit Unearned Revenue $9,600, then expense December's $800 expired month (debit Software Expense, credit Prepaid Software). After both entries, prepaid is $8,800 and expense is $800.
Asset-method versus expense-method mix-ups
Mix-ups happen when one person records the cash and another records the adjustment from a different playbook.
Case A — expense original, asset-method adjusting. Original on January 1: debit Insurance Expense $12,000 for a calendar-year policy. Wrong year-end "adjustment" copied from an asset-method checklist: debit Insurance Expense $12,000, credit Prepaid Insurance $12,000 (expensing the whole year again as if prepaid still sat on the books). Result: insurance expense $24,000; Prepaid Insurance a $12,000 credit. Correction: reverse the bogus adjusting entry (debit Prepaid Insurance $12,000, credit Insurance Expense $12,000). After the reverse, expense is back to $12,000, which is actually correct for a policy that expired on December 31 — so no further prepaid is needed. If instead the policy still had remaining months, reverse the bogus entry and then post the expense-method correcting entry for the remaining prepaid.
Case B — asset original, expense-method adjusting. Original on December 1: debit Prepaid Insurance $18,000, credit Cash $18,000. Wrong December 31 adjustment using the expense-method formula for remaining coverage: debit Prepaid Insurance $16,500, credit Insurance Expense $16,500. That increases prepaid to $34,500 and credits expense $16,500 (negative expense). Correction: reverse the bad adjustment entirely (debit Insurance Expense $16,500, credit Prepaid Insurance $16,500), then post the asset-method expired slice: debit Insurance Expense $1,500, credit Prepaid Insurance $1,500. Ending prepaid = $16,500; expense = $1,500.
| Original method | Correct remaining or expired math | Wrong partner entry | First repair |
|---|---|---|---|
| Expense method | Remaining prepaid = unexpired fraction × cash paid | Debit expense, credit prepaid (asset-method expire) | Reverse the wrong adjuster; then debit prepaid for remaining |
| Asset method | Expired expense = expired fraction × cash paid | Debit prepaid, credit expense (expense-method setup) | Reverse the wrong adjuster; then debit expense for expired |
The mechanical test: after the correction, the prepaid or unearned balance must equal the unexpired or unearned dollars, and the income-statement account must equal the expired or earned dollars for this period. If Prepaid Insurance has a credit balance, or Unearned Revenue has a debit balance, a method mix-up is the first suspect.
Putting a deferral correction through the statements
Take Cedar Street's $18,000 expense-method insurance with no adjustment. After the $16,500 correcting debit to Prepaid Insurance:
- Income statement: Insurance Expense $1,500 (was $18,000).
- Balance sheet: Prepaid Insurance $16,500 (was $0); cash already reduced $18,000.
- Equity: $16,500 higher than the uncorrected draft, because expense fell.
Take Riverton's $15,600 income-method retainer with no adjustment. After the $14,300 correcting credit to Unearned Revenue:
- Income statement: Service Revenue $1,300 (was $15,600).
- Balance sheet: Unearned Revenue $14,300 (was $0); cash already increased $15,600.
- Equity: $14,300 lower than the uncorrected draft.
Those two financial-statement maps are the same maps Section 5.3 uses when the bookkeeper fails to correct before statements go out. The journal entries in this section are how you keep that from happening while the year is still open.
Exam traps
- Debiting Cash on a deferral correction. Cash already moved on day one.
- Expensing the remaining prepaid instead of the expired slice after an expense-method original entry.
- Crediting Service Revenue to "set up" unearned after an income-method original entry. You reduce revenue; you do not increase it.
- Stopping after reclassifying a vendor prepayment out of Accounts Payable and forgetting to expense the month that has already elapsed.
- Treating a credit balance in Prepaid Insurance as a liability to leave alone. It is usually a method mix-up that still needs reversing.
On December 1 Cedar Street Bakery paid $18,000 for a 12-month policy and debited Insurance Expense for the full amount. No adjustment was made at December 31. The books are still open. What correcting entry sets up the remaining prepaid?
On December 1 Riverton Storage collected $15,600 for 12 months of service beginning that day and credited the full amount to Service Revenue. No adjusting entry was made. What December 31 correcting entry records the unearned remainder?
Cedar Street prepaid a supplier $7,200 for packaging to be delivered over 12 months and debited Accounts Payable instead of Prepaid Packaging. Cash is correct. What is the first correcting entry to reclassify the original posting?
