Rectification of Errors in Accounting: Types, Methods & Journal Entries Explained

Rectification of errors in accounting involves identifying and correcting mistakes made during the recording, posting, or balancing of financial transactions. These errors can be categorized into errors of principle, omission, commission, and compensating errors—some of which affect the trial balance, while others do not.

Depending on when the errors are detected—before the trial balance, after the trial balance, or in the next accounting period—they are rectified using statements, journal entries, or with the help of a suspense or profit and loss adjustment account. Proper rectification ensures accurate financial statements and maintains the integrity of accounting records.

4. Recheck ledger balances.
5. Compare with previous period balances.
6. Check postings related to difference amount.

Rectification Techniques

A. Before Trial Balance

• Use rectification statements in affected accounts.
• Examples include wrong postings, side errors, etc.

B. After Trial Balance (Before Final Accounts)
