One-sided Errors, Suspense Account and P&L Adjustment: ISC Class 11 Accounts

Updated 17 October 2026 · Fact-checked

A one-sided error affects only one account (a debit or credit not posted, or a wrong total), so the trial balance does not agree. The difference is entered in a Suspense Account (debit if the debit side was short, credit if the credit side was short) to make it agree. Each error found is rectified through the suspense account until it is closed. Errors found after final accounts are rectified through the Profit and Loss Adjustment Account.

Debit short means Suspense Dr, credit short means Suspense Cr; rectify until nil, but after final accounts use the P&L Adjustment A/c.

Understand One-sided Errors, Suspense Account and the Profit and Loss Adjustment Account

One-sided errors. Omitting one side of an entry, posting to one side only, wrong totalling (overcasting or undercasting), wrong balancing, or posting an amount differently on the two sides. They cause a trial balance difference.

Suspense Account. A temporary account opened to make the trial balance agree.

If the *debit* side is short (credit total larger): Suspense A/c is *debited* with the difference, shown on the debit side of the trial balance.
If the *credit* side is short: Suspense A/c is *credited*.

Rectifying through the suspense account. For each error found, pass a journal entry using the suspense account to put the missing side. If the missing side was a debit, debit the account and credit Suspense. If the missing side was a credit, credit the account and debit Suspense. Rectifying a nominal-account error alters profit; an error in a personal or real account does not.

Overcast on credit side (credit too high): Debit that account, credit Suspense.
Undercast on debit side (debit too low): Debit that account, credit Suspense.

After all errors are corrected, the suspense account is closed (nil balance). If a balance remains, there are still undiscovered errors.

Rectification after final accounts. Nominal accounts are closed, so profit-affecting errors go through the *Profit and Loss Adjustment Account*. Debit it for additional expenses or lost incomes; credit it for omitted incomes or excess expenses. The balance is then transferred to Capital. Errors in personal and real accounts need no P&L Adjustment.

Effect on profit. Corrected profit: add omitted incomes, subtract overstated incomes, add back excess expenses and subtract omitted expenses.

Steps to prepare the suspense account. Credit or debit the opening difference first, then post each rectification on the opposite side to show a closing nil balance.

One-sided Errors, Suspense Account and the Profit and Loss Adjustment Account: key facts

Suspense balance: Suspense = Difference in trial balance | Debit if credit total is larger, credit if debit total is larger; Opened to agree the trial balance.
Closure check: Sum of rectifications through suspense = Opening suspense balance | Closing balance nil; If not nil, errors remain.
Profit effect: Corrected profit = Reported profit - Overstated incomes - Omitted expenses + Omitted incomes + Excess expenses | Only nominal errors; Personal and real errors do not change profit.

How to answer One-sided Errors, Suspense Account and the Profit and Loss Adjustment Account questions

1Compare totals and open the suspense account on the correct side.
2For each error, identify the missing or wrong side.

One-sided Errors, Suspense Account and the Profit and Loss Adjustment Account: solved examples

Ordered from board level to HOTS. Try each one before you open the solution.

Example 1: Suspense side · 1 mark · MCQBoard level

If the debit total of the trial balance is less than the credit total, the suspense account is:
(a) credited (b) debited (c) closed (d) ignored

Try it first, then show the solutionSolution

Debit is short, so Suspense is debited.

Answer: (b) debited

Example 2: Opening the suspense account · 3 marks · Short answerBoard level

The trial balance totals are: debit Rs 5,43,500; credit Rs 5,50,000. Show the entry in the trial balance and state the side of the suspense account. (3 marks)

Try it first, then show the solutionSolution

Credit exceeds debit by 6,500.
Suspense A/c is added on the debit side, 5,43,500 + 6,500 = 5,50,000.

Answer: Suspense A/c Dr Rs 6,500 (debit side of the trial balance).

Example 3: Rectify and close the suspense · 8 marks · Long answerHarder board level

The suspense account shows Rs 6,500 (Dr). Errors found: (i) Sales book overcast by Rs 1,000; (ii) cash received from Mona Rs 4,000 credited to her account but not entered in the cash book; (iii) Purchases book undercast by Rs 1,500. Pass rectifying entries, prepare the suspense account and find the effect on profit if profit was Rs 1,00,000. (8 marks)

Try it first, then show the solutionSolution

(i) Sales Dr 1,000, To Suspense 1,000.
(ii) Cash Dr 4,000, To Suspense 4,000.
(iii) Purchases Dr 1,500, To Suspense 1,500.
Total credited = 6,500 which clears the debit balance.
Profit falls by 1,000 + 1,500 = 2,500: corrected profit Rs 97,500.

Answer:

Suspense A/c Dr	Rs	Cr	Rs
To Balance (TB difference)	6,500	By Sales	1,000
		By Cash (Mona)	4,000
		By Purchases	1,500
Total	6,500	Total	6,500

Corrected profit Rs 97,500.

Example 4: Profit and Loss Adjustment Account · 8 marks · Long answerHarder board level

After the final accounts, these errors are found: (a) salary of Rs 6,000 paid to the owner was debited to Salaries; (b) rent outstanding Rs 3,000 was omitted; (c) a machine of Rs 20,000 was debited to Purchases (charge depreciation of 10% for the year). Pass entries, prepare the Profit and Loss Adjustment Account and transfer the balance. (8 marks)

Try it first, then show the solutionSolution

(a) Drawings Dr 6,000, To P&L Adjustment 6,000.

(c) Machinery Dr 20,000, To P&L Adjustment 20,000; P&L Adjustment Dr 2,000, To Machinery 2,000.
Credits 6,000 + 20,000 = 26,000; debits 3,000 + 2,000 = 5,000; net credit 21,000.
P&L Adjustment Dr 21,000, To Capital 21,000.

Answer: Net profit increases by Rs 21,000, transferred to Capital.

Example 5: Unresolved difference · 4 marks · Short answerHOTS / competency

The suspense account has a balance of Rs 6,500 Dr. Errors found total Rs 5,400 (credited to suspense). Explain what the remaining balance means and what the accountant should do before the final accounts. (4 marks)

Try it first, then show the solutionSolution

Remaining balance = 6,500 - 5,400 = Rs 1,100 Dr.
It means errors of Rs 1,100 are still undiscovered.
Continue to look for them; if not found, show the balance in the balance sheet (an asset if debit, a liability if credit) and flag it.

Answer: Rs 1,100 of errors are still hidden; keep searching, and show the suspense balance in the balance sheet if unresolved.
