What are typical errors that could cause the trial balance to not balance, and how would you approach them?

• A. Transposition errors, single-entry errors, and incorrect debit/credit posting; re-check journal entries, verify ledger balances, and re-run the trial balance.
• B. Only arithmetic mistakes in the trial balance; no action needed.
• C. Currency conversion errors; adjust exchange rates.
• D. The trial balance always balances; no action needed.

Answer: (A)

When a trial balance doesn’t balance, it’s usually because something in recording or posting disrupted the equal relationship between debits and credits. The best answer points to the typical culprits: transposition errors (digits swapped in a posting), single-entry errors (one side of a transaction is missing or only partially recorded), and incorrect debit/credit posting (posting to the wrong account or on the wrong side). To approach this, start by tracing each journal entry to its ledger postings to confirm that every transaction has both a debit and a credit and that the amounts match. Recalculate the ledgers and then re-run the trial balance to see where the mismatch lies. This systematic check often reveals the source, such as a swapped digit, a missing side, or a posting to the wrong account, which you can then correct and verify again. Context: the trial balance lists all ledger balances and should show total debits equal total credits because of double-entry recording. Other options aren’t the best fit: arithmetic mistakes in the trial balance would still require scrutiny and correction, currency conversion issues are not the typical cause in a straightforward set of books, and it is not true that the trial balance always balances—when it doesn’t, it signals recording or posting errors that need investigation.
