Mistaken idea “Each financial statement can be corrected independently”

Correction

Correct the underlying account balances, then update every affected statement. For example, correcting an omitted wage accrual changes expense, the liability, net income, and ending equity.

Why the mistaken idea can seem reasonable

A missing expense is easiest to notice on the income statement. It can seem reasonable to add the expense there and leave the other finished statements alone. But the expense may also change an asset or liability, and the resulting net income affects retained earnings.

Follow the accounting through the reports

Start with the underlying account balances. A wage accrual records both wage expense and wages payable. Correcting the omitted accrual reduces net income and increases the liability. The lower income also reduces ending retained earnings and total equity.

Changing only the income statement leaves the equity statement using the old income. Changing only Retained Earnings on the balance sheet leaves the equity statement unexplained. Prepare the reports from the same corrected balances.

Agreement does not prove accuracy

If the same wage accrual is omitted everywhere, understated liabilities can offset overstated equity. The balance sheet can balance, and the shared income amount can agree, while both reports remain wrong. Checking the adjustment evidence is a separate task from checking the repeated amounts.

Check the reports you are comparing

Confirm the company, period, reporting date, and units before comparing totals. Also check whether one file was prepared before an adjustment and another after it. Dollars and thousands of dollars cannot be compared as though the printed numbers use the same unit.

The statement-diagnostics lesson works through a standalone wage-accrual example. Use it to trace the correction instead of inventing a Retained Earnings amount to make a report balance.
