IGCSE Accounting — Trial Balance and Correction of Errors: Notes, Practice Questions & Worked Solutions

IGCSE Accounting 0452 · Section 3: Verification of Accounting Records

Trial Balance and Correction of Errors

A trial balance checks that total debits equal total credits — but a balanced trial balance does NOT prove the accounts are error-free, since some errors don’t disturb the balance at all.

1. The Trial Balance

A trial balance lists every ledger account balance, split into debit and credit columns. If double entry has been applied correctly, the two column totals will be equal. Its main limitation: it only checks arithmetic accuracy, not that the correct accounts were used.

2. Errors NOT Revealed by a Trial Balance

Error type	Description
Commission	Correct amount and side, but posted to the wrong account of the correct type (e.g. wrong customer’s account)
Compensating	Two unrelated errors happen to cancel each other out
Complete reversal	Correct amount and accounts, but debit and credit are swapped
Omission	A transaction is left out of the records entirely
Original entry	The wrong amount is entered on both sides (correct accounts, correct sides, wrong figure — the same wrong figure both times)
Principle	Posted to the wrong class/type of account (e.g. capital expenditure treated as revenue expenditure)

Worked example — correcting a complete reversal error Goods sold for $300 to J. Smith were recorded as: Debit Sales $300, Credit J. Smith $300 (the entries were completely reversed). Give the journal entry to correct this.
To fix a complete reversal, you must both cancel the wrong entry AND post the correct one — so the correcting entry is double the original amount: Debit J. Smith $600, Credit Sales $600.

3. Suspense Accounts

When an error DOES cause the trial balance to be unequal, a suspense account is opened temporarily with the difference, so the trial balance can balance while the error is investigated. Once found, a journal entry corrects the error and clears the suspense account.

Worked example — using a suspense account A trial balance’s debit column totals $50 less than its credit column. A suspense account is opened with a debit balance of $50. It’s later found that a $50 purchase was correctly credited to the supplier’s account, but never debited to Purchases. Give the correcting journal entry.
Debit Purchases $50, Credit Suspense $50 — this both records the missing debit entry and clears the suspense account to zero.

Common mistakes to watch for

Assuming a balanced trial balance means the accounts are completely correct — six specific error types can still be present.
Forgetting that correcting a reversal error requires DOUBLE the original amount, not the original amount again.
Opening a suspense account for an error that doesn’t actually cause an imbalance (like the six error types above) — suspense accounts are only needed when the trial balance fails to balance.

Key Vocabulary Recap

Trial balance — a list of all ledger balances, checking debits equal credits

Trial Balance and Correction of Errors — Practice

Covers: the trial balance, the six error types not revealed by it, and suspense accounts. 10 questions.

State the purpose of a trial balance.

Explain one limitation of a trial balance.

Name and describe the error where a transaction is posted to the wrong account of the correct type (e.g. the wrong customer’s account).

Name and describe the error where a transaction is left out of the accounting records entirely.

Name and describe the error where capital expenditure is treated as revenue expenditure.

Name and describe the error where two unrelated errors happen to cancel each other out in the trial balance.

Goods sold for $250 to R. Khan were recorded as Debit Sales $250, Credit R. Khan $250 (a complete reversal). Give the journal entry to correct this.

Explain when a suspense account is opened.

A trial balance’s credit column totals $80 more than its debit column. A suspense account is opened. It is later found that a $80 discount allowed was never posted to the discount allowed account. Give the correcting journal entry.

Q10

Explain why correcting an error can affect the profit for the year reported in the financial statements.

Trial Balance and Correction of Errors — Practice: Solutions

Purpose of a trial balance.

✓A trial balance lists all ledger account balances to check that total debits equal total credits, confirming the arithmetic accuracy of the double-entry postings.

One limitation of a trial balance.

✓A trial balance can still balance even when errors exist — for example, an error of complete omission, principle, commission, original entry, complete reversal, or a compensating error will not cause it to fail to balance.

Wrong account of correct type.

✓This is an error of commission — the correct amount is entered on the correct side, but in the wrong account of the correct class (e.g. posted to the wrong customer’s account instead of the right one).

Transaction left out entirely.

✓This is an error of omission — the transaction is not recorded anywhere in the books at all.

Capital expenditure treated as revenue.

✓This is an error of principle — the transaction is posted to the wrong class/type of account (capital rather than revenue expenditure).

Two unrelated errors cancel out.

✓This is a compensating error — two separate, unrelated errors happen to be equal and opposite, so they cancel out and the trial balance still balances.

Correct a reversal: Sales$250/R.Khan$250 reversed.

✓Debit R. Khan $500, Credit Sales $500 (double the original amount, to both cancel the wrong entry and post the correct one)

When is a suspense account opened?

✓A suspense account is opened when the trial balance fails to balance, using the difference between the two column totals, so that the accounts can be shown as balanced while the underlying error is investigated.

Credit column $80 more; discount allowed $80 not posted.

✓Debit Discount Allowed $80, Credit Suspense $80 (this records the missing expense debit and clears the suspense account, which had a debit balance of $80)

Q10

Why can error correction affect reported profit?

✓If the original error involved an income or expense account (e.g. an expense was omitted, or posted as the wrong amount), correcting it changes the figures used in the statement of profit or loss — so the reported profit for the year changes once the correction is made.
