4.2 Error Corrections
Key Takeaways
- Accounting errors are not accounting changes; they represent mistakes, misapplications of GAAP, or oversights of facts that existed when statements were prepared.
- Correcting an accounting error requires a restatement of prior period financial statements, and the adjustment is reported as a prior period adjustment to beginning Retained Earnings (net of tax).
- Counterbalancing errors automatically correct themselves over two consecutive fiscal periods, meaning the cumulative balance sheet effect becomes zero after the second period.
- Non-counterbalancing errors do not automatically offset in the next period and require corrective journal entries until the asset or liability is derecognized.
- A change from a non-GAAP method (like cash basis) to a GAAP method (accrual basis) is classified as an error correction, not a change in accounting principle.
Error Corrections and Restatements
While accounting changes represent deliberate choices to adopt new principles or adjust estimates due to new circumstances, accounting errors represent mistakes. Errors result from mathematical mistakes, mistakes in applying accounting principles, or the oversight or misuse of facts that existed when the financial statements were prepared.
Under ASC 250, the correction of an error is not classified as an accounting change. Instead, it is treated as a prior period adjustment and requires restatement of prior period financial statements.
1. Accounting for Error Corrections
When an error is discovered in a previously issued financial statement, the accounting treatment depends on when the error is found:
- Current Year Discovery of Current Year Error: The error is corrected before the statements are issued.
- Current Year Discovery of Prior Year Error: If the error is material, the prior period financial statements must be restated.
- Prior Period Adjustment: The cumulative effect of the error on periods prior to the earliest period presented is reported as an adjustment to the opening balance of Retained Earnings (net of tax) for that earliest period.
Non-GAAP to GAAP: A Crucial CPA Exam Distinction
A common trap on the exam is a scenario where a company changes from an incorrect, non-GAAP method of accounting to a correct, GAAP-compliant method (for example, switching from cash-basis accounting to accrual-basis accounting, or changing from expensing equipment to capitalizing and depreciating it). Because the original method was non-GAAP, this transaction is classified as an Error Correction (requiring restatement and prior period adjustment), NOT a change in accounting principle.
2. Counterbalancing vs. Non-Counterbalancing Errors
Errors can be classified into two operational categories: counterbalancing and non-counterbalancing.
A. Counterbalancing Errors
Counterbalancing errors are errors that will automatically correct (offset) themselves over two consecutive accounting periods. Even if the company makes no correcting journal entry, the cumulative Retained Earnings balance at the end of the second year will be correct, though the individual accounts (such as Net Income, Assets, Liabilities, and ending Retained Earnings) will be misstated in the first year.
Common examples of counterbalancing errors include:
- Ending Inventory Errors: Overstating or understating ending inventory.
- Accrued Expense Errors: Failing to record accrued wages at year-end.
- Prepaid Expense Errors: Overstating or understating prepaid expenses.
- Unearned Revenue Errors: Recording unearned revenue as sales revenue when received.
The Mechanics of an Ending Inventory Error
Consider the impact of understating Ending Inventory in Year 1 by $10,000:
- Year 1: Ending Inventory is understated $\rightarrow$ Cost of Goods Sold (COGS) is overstated $\rightarrow$ Net Income is understated $\rightarrow$ Ending Retained Earnings is understated.
- Year 2: Beginning Inventory is understated (carried forward from Year 1) $ ightarrow$ Cost of Goods Sold is understated $ ightarrow$ Net Income is overstated $ ightarrow$ Ending Retained Earnings is correct (the Year 1 understatement of $10,000 is offset by the Year 2 overstatement of $10,000).
| Year | Beginning Inventory | Cost of Goods Sold | Net Income | Ending Retained Earnings |
|---|---|---|---|---|
| Year 1 | Correct | Overstated by $10k | Understated by $10k | Understated by $10k |
| Year 2 | Understated by $10k | Understated by $10k | Overstated by $10k | Correct |
If a counterbalancing error is discovered before the books are closed in Year 2, an adjusting entry is required to correct the accounts. If discovered after the books are closed in Year 2, no adjusting entry is needed because the balances have counterbalanced, but historical financial statements presented for comparison must still be restated.
B. Non-Counterbalancing Errors
Non-counterbalancing errors are errors that do not automatically offset themselves over two consecutive accounting periods. These errors continue to misstate the financial statements until a correcting journal entry is made or the related asset/liability is sold, retired, or fully depreciated.
Common examples of non-counterbalancing errors include:
- Failing to Record Depreciation Expense: Overstates Net Income, Assets, and Retained Earnings indefinitely.
- Expensing a Capitalizable Asset: Understates Net Income and Assets in the year of purchase, and understates depreciation expense in subsequent years.
3. Worked Examples and Journal Entries
Example A: Accrued Wages (Counterbalancing Error)
On December 31, 2025, Apex Corp failed to accrue wages of $15,000. The error was discovered in November 2026 before the 2026 books were closed. The 2025 books were already closed.
Because the 2025 books are closed, the understated expense of $15,000 has closed into Retained Earnings (leaving it overstated). In 2026, when these wages were paid, they were likely debited to Wages Expense, overstating 2026 Wages Expense.
To correct this in 2026:
| Account | Debit | Credit |
|---|---|---|
| Retained Earnings (Beginning) | $15,000 | |
| Wages Expense | $15,000 |
Explanation: The debit to Retained Earnings corrects the overstated beginning balance from 2025. The credit to Wages Expense reduces the overstated current year expense.
Example B: Unrecorded Depreciation (Non-Counterbalancing Error)
On January 1, 2024, Delta Corp purchased equipment for $50,000. The equipment has a 5-year useful life, no salvage value, and is depreciated using straight-line. Delta failed to record depreciation in both 2024 and 2025. The error was discovered in 2026 before the books were closed. The tax rate is 20%.
Straight-line depreciation is $10,000 per year. For 2024 and 2025, total unrecorded depreciation is $20,000.
To correct this error in 2026, Delta must record the prior period adjustment:
| Account | Debit | Credit |
|---|---|---|
| Retained Earnings (Beginning) ($20,000 × 80%) | $16,000 | |
| Deferred Tax Asset or Income Taxes Payable ($20,000 × 20%) | $4,000 | |
| Accumulated Depreciation — Equipment | $20,000 |
Explanation: Accumulated Depreciation is credited for the cumulative two-year depreciation ($20,000). Retained Earnings is debited net of tax ($16,000), and tax effects are recorded accordingly. Current year (2026) depreciation of $10,000 will be recorded normally at year-end.
A company changes its accounting method from the cash basis to the accrual basis to conform with GAAP. How should this change be reported under ASC 250?
A company understated its ending inventory on December 31, Year 1, by $10,000. If the error is not discovered, what is the effect of this error on Year 2 ending retained earnings and Year 2 net income, respectively?
On December 31, Year 1, a company failed to accrue $8,000 of interest expense. The error was discovered in Year 2 before the Year 2 books were closed. The interest was paid in Year 2 and recorded entirely as Interest Expense for Year 2. What is the correcting journal entry in Year 2?
