Use a suspense account to correct trial-balance errors
Temporarily record an unexplained difference, then post evidence-based correcting entries and check that suspense clears.
Cambridge International AS & A Level Accounting 9706, 2026–2028 syllabus, Version 2. These lessons cover Topic 1.4 only. Practice is self-checked, not an official Cambridge grade; the separately published 2029 syllabus, timed papers and human subject-teacher review remain outstanding.
Before you begin
- Use double-entry, ledger and trial-balance knowledge from Topic 1.2. Reconciliations compare records with independent or separately maintained evidence; an unexplained difference needs investigation.
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
A $900 credit sale has a correct debit to receivables but no credit to sales. Which side is missing?
What you will learn
- Open and use a suspense account for an unexplained trial-balance difference
- Prepare journal and ledger entries to correct errors
- Explain when the suspense account should clear
Use suspense only as a temporary balance
When debit and credit totals differ and the cause is not yet known, the difference may be placed on the smaller side of the trial balance in a suspense account. This makes the columns agree temporarily; it is not evidence that the underlying records are correct.
Once an error is found, prepare a correction that puts the missing or wrong amount into the proper accounts. The entry must reflect what was actually recorded and what should have been recorded; never debit or credit suspense just to force it to zero.
Check the correction from the original entry
Write down the original debit and credit, identify the correct debit and credit, then compare them. If one side is already correct, correct only the other side. If a side is present but the amount is wrong, post the difference to that account and the opposite entry to suspense when appropriate.
After all identified errors are corrected, the suspense account should clear. A remaining balance means an error is still unidentified or a correction may be incomplete; investigate it before finalising the statements.
Pause and explain
After all identified errors are corrected, what should happen to the suspense account?
Worked example
A $640 credit sale was debited correctly to a customer, but the sales account was credited with only $460. The $180 trial-balance difference was placed in suspense. Correct the error.
Show the worked solution
- The debit to the customer's account is already correct at $640.
- Sales is understated by $180, so debit suspense $180 and credit sales $180.
- This correction removes the $180 suspense balance and completes the sale entry.
Answer Dr Suspense $180; Cr Sales $180. The receivable entry is already correct, sales increases by $180 and suspense clears.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
A $1,250 debit purchase of equipment was correctly debited to equipment, but bank was credited by $1,025. A $225 suspense credit was used. Give the correction.
Give me a hint
The bank credit is too small; compare recorded and correct amounts.
Compare my reasoning
- The bank account needs a further credit of $225.
- Debit suspense $225 to remove the temporary credit balance.
- The equipment debit is already correct and should not be repeated.
Dr Suspense $225; Cr Bank $225. This increases the bank credit to $1,250 and clears suspense.
Look for these in your work
- Difference calculated
- Correct account adjusted
- Suspense cleared
A $520 cash receipt from a customer was credited correctly to bank but debited to purchases instead of receivables. Does this error require suspense? Give the correction.
Give me a hint
Both entries exist, so consider whether the debit and credit totals differ.
Compare my reasoning
- The credit to bank is correct; the debit is in the wrong account.
- Debit receivables $520 and credit purchases $520 to reverse the wrong debit and place it in the correct account.
- Because both sides were posted, the trial-balance totals already agree and suspense is not required.
No suspense is needed. Dr Receivables $520; Cr Purchases $520. This removes the incorrect debit and records the customer balance reduction.
Look for these in your work
- No suspense justified
- Correction reverses wrong account
- Correct account stated
A suspense balance remains after three listed corrections. A bookkeeper proposes crediting income with the remainder. Evaluate the proposal.
Give me a hint
Ask whether the remainder has supporting evidence and whether the account effect is known.
Compare my reasoning
- The remaining amount signals an unresolved error or an incomplete correction.
- A credit to income would alter profit without identifying the original transaction.
- Recheck the trial-balance extraction, original records and each correction before posting further entries.
Do not post the remainder to income without evidence. Investigate the balance and identify the underlying account; otherwise the statements may be misstated.
Look for these in your work
- Unresolved balance interpreted
- Profit risk identified
- Evidence-led next step
Common mistakes
- Using suspense as a permanent balance
- Repeating a side of the original transaction that was already correct
- Posting an unexplained difference directly to profit
