A Trial Balance is a statement showing all ledger account balances arranged in debit and credit columns. If the double-entry system has been followed correctly, the total of debit balances must equal the total of credit balances.
Purpose of Trial Balance: 1. To check the arithmetical accuracy of ledger postings 2. To serve as the basis for preparing financial statements 3. To help in locating errors
Methods of preparing Trial Balance: - Balance Method — Only closing balances of each account are listed (most common) - Totals Method — Totals of debit and credit sides of each account are listed - Totals and Balance Method — Combines both
Errors NOT revealed by Trial Balance: 1. Errors of omission (transaction completely omitted) 2. Errors of commission (posted to wrong account of same type) 3. Errors of principle (capital item treated as revenue or vice versa) 4. Compensating errors (two errors of equal amount cancel out) 5. Errors of original entry (wrong amount in journal carried through) 6. Errors of complete reversal (debit and credit reversed)
Errors revealed by Trial Balance: One-sided errors like posting only one side of an entry, posting wrong amount to one account, arithmetic errors in balancing, and omission of posting to one account.
Exam tip: ICAI typically gives a Trial Balance that does not agree and asks you to find and rectify errors. Master the distinction between one-sided and two-sided errors.
