How to Use This Page
Solve each Samacheer Kalvi exercise question on your own first, then compare your rectification entries. The key skill is identifying the TYPE of error and whether it's one-sided or two-sided — that determines whether you need a Suspense Account.
Key Concepts (Quick Recap)
Types of Errors
| Error Type | Description | Affects TB? |
|---|
| Error of Omission | Transaction not recorded at all (complete) | No |
| Error of Partial Omission | One side of the transaction recorded, other side omitted | Yes |
| Error of Commission | Wrong amount or wrong account but correct side | Depends |
| Error of Principle | Capital item treated as revenue or vice versa | No |
| Compensating Error | Two errors that cancel each other out | No |
| Error of Original Entry | Wrong amount recorded in the original document | No |
One-sided vs Two-sided Errors
One-sided errors (affect only one account):
- Wrong posting to one account
- Omission of posting to one account
- Posting to the wrong side of one account
- Wrong amount on one side
- → Affect the trial balance → Use Suspense Account
Two-sided errors (affect two accounts):
- Error of omission (complete)
- Error of principle
- Compensating errors
- Error of commission (same amount on both sides)
- → Do NOT affect the trial balance → Pass correcting journal entry
Rectification Process
Step 1: Identify the error Step 2: Determine if it's one-sided or two-sided Step 3: Determine if it's before or after trial balance
Before Trial Balance:
- Correct by posting directly to the affected ledger accounts
After Trial Balance (before final accounts):
- One-sided errors → Use Suspense Account
- Two-sided errors → Pass correcting journal entry
After Final Accounts:
- Errors affecting P&L items → Through Profit & Loss Adjustment Account
- Errors affecting balance sheet items → Correct the asset/liability directly
Suspense Account
- Opened when trial balance does not agree
- The difference is put on the shorter side
- Errors are rectified one by one
- Each rectification reduces the Suspense Account balance
- When all errors are rectified, Suspense Account has nil balance
I. Choose the Best Answer (MCQs)
Q1. An error of omission means (a) Transaction is recorded twice (b) Transaction is not recorded at all (c) Transaction is recorded on the wrong side (d) Transaction is recorded with the wrong amount
Answer(b) Transaction is not recorded at all — Error of omission means the transaction is completely left out of the books. Neither the debit nor the credit is recorded.
Q2. Error of principle occurs when (a) A transaction is omitted (b) A transaction is recorded with wrong amount (c) A capital expenditure is treated as revenue expenditure (d) A transaction is recorded on the wrong side
Answer(c) A capital expenditure is treated as revenue expenditure — Error of principle occurs when an item is recorded in the wrong category — e.g., purchase of machinery (capital) recorded as purchase of goods (revenue).
Q3. A suspense account is used to rectify (a) Two-sided errors (b) One-sided errors (c) Both types of errors (d) Neither type of error
Answer(b) One-sided errors — A suspense account is used when the trial balance does not agree due to one-sided errors. Two-sided errors are rectified by passing correcting journal entries.
Q4. Compensating errors (a) Are disclosed by trial balance (b) Are not disclosed by trial balance (c) Affect only one account (d) Are easy to detect
Answer(b) Are not disclosed by trial balance — Compensating errors are two or more errors that cancel each other out. Since the net effect on debits and credits is zero, the trial balance still agrees.
Q5. Purchase of machinery recorded in the purchases book is an error of (a) Omission (b) Commission (c) Principle (d) Compensating
Answer(c) Principle — Purchase of machinery is a capital expenditure (creating an asset). Recording it in the purchases book treats it as a revenue expenditure. This is an error of principle.
II. Fill in the Blanks
1. An error where a transaction is not recorded at all is called error of omission. 2. An error where a capital expenditure is treated as revenue expenditure is called error of principle. 3. Errors that cancel each other out are called compensating errors. 4. A suspense account is opened to balance the trial balance when there is a difference between debits and credits. 5. One-sided errors are disclosed by the trial balance. 6. Two-sided errors are not disclosed by the trial balance. 7. Error of complete omission affects neither side of the trial balance. 8. Error of partial omission affects one side of the trial balance. 9. Purchase of furniture recorded in the purchases book is an error of principle. 10. When all one-sided errors are rectified, the suspense account balance becomes nil/zero.
III. True or False (with corrections for false statements)
Q1. Error of omission is always disclosed by the trial balance.
AnswerFalse — Correction: Error of COMPLETE omission is NOT disclosed by the trial balance because neither the debit nor the credit side is recorded. Only PARTIAL omission (one side recorded, other omitted) is disclosed.
Q2. Error of principle does not affect the trial balance.
AnswerTrue — Error of principle affects two accounts (one debited, one credited) with the same amount. The trial balance still agrees.
Q3. A suspense account is a permanent account.
AnswerFalse — Correction: A suspense account is a TEMPORARY account. It is opened to balance the trial balance and is closed when all errors are found and rectified.
Q4. Compensating errors are disclosed by the trial balance.
AnswerFalse — Correction: Compensating errors are NOT disclosed by the trial balance because two or more errors cancel each other out, and the net effect on debits and credits is zero.
Q5. Rectification of a one-sided error requires a suspense account.
AnswerTrue — One-sided errors affect only one account and cause a mismatch in the trial balance. A suspense account is used to make the rectification entry.

V. Answer Briefly (2-mark questions)
Q1. What are the types of errors in accounting?
Answer
1. Error of Omission: Transaction not recorded at all 2. Error of Commission: Transaction recorded with wrong amount or wrong account 3. Error of Principle: Capital item treated as revenue or vice versa 4. Compensating Error: Two errors that cancel each other 5. Error of Original Entry: Wrong amount in the original document (posted to both sides)
Q2. Distinguish between one-sided and two-sided errors.
Answer
| Feature | One-sided Error | Two-sided Error | |---|---|---| | Affects | Only one account | Two accounts | | Disclosed by TB? | Yes | No | | Rectification | Through Suspense A/c | Through correcting journal entry | | Example | Omitting to post to Ram's A/c | Complete omission of a transaction |
Q3. What is a suspense account? When is it closed?
Answer
A suspense account is a temporary account opened when the trial balance does not agree. The difference between the debit and credit totals is placed in the suspense account. It is closed when all one-sided errors are found and rectified. If the suspense account balance becomes zero after rectifications, all errors have been corrected.
Q4. Give two examples each of errors disclosed and not disclosed by the trial balance.
Answer
Errors Disclosed by TB (one-sided): 1. Posting ₹500 to the debit of Ram's A/c instead of ₹50 (wrong amount on one side) 2. Omitting to post the credit side of a purchase transaction to the creditor's account Errors NOT Disclosed by TB (two-sided): 1. Purchase of goods ₹5,000 from Sita completely omitted from the books 2. Purchase of furniture ₹10,000 recorded as Purchase of goods (error of principle)
VI. Answer in Detail (5-mark questions)
Q1. Rectify the following errors (before preparing the trial balance):
Answer
(i) Purchase of goods ₹5,000 from Ram recorded as ₹500 in the Purchases Book (ii) Sale of goods ₹3,000 to Suresh not recorded in the Sales Book (iii) Purchase of furniture ₹10,000 recorded in the Purchases Book (iv) Cash paid to Mohan ₹2,000 not posted to his account (v) Salary paid ₹5,000 debited to Salary A/c as ₹500
Rectification Entries:
(i) Purchase of goods ₹5,000 from Ram recorded as ₹500: This is a two-sided error (both Purchases A/c and Ram's A/c are understated by ₹4,500).
Purchases A/c Dr 4,500
To Ram A/c 4,500
(Being purchase undercast by ₹4,500 now rectified)
(ii) Sale of goods ₹3,000 to Suresh not recorded: This is a complete error of omission. Both sides are missing.
Suresh A/c Dr 3,000
To Sales A/c 3,000
(Being sale of goods to Suresh omitted, now recorded)
(iii) Purchase of furniture ₹10,000 recorded in the Purchases Book: This is an error of principle. Furniture (capital expenditure) was treated as purchases (revenue expenditure).
Furniture A/c Dr 10,000
To Purchases A/c 10,000
(Being purchase of furniture wrongly recorded in Purchases Book, now rectified)
(iv) Cash paid to Mohan ₹2,000 not posted to his account: This is a one-sided error. Cash A/c is correctly credited, but Mohan's A/c is not debited.
Mohan A/c Dr 2,000
To Suspense A/c 2,000
(Being cash paid to Mohan not posted to his account, now rectified)
(v) Salary paid ₹5,000 debited as ₹500: This is a one-sided error. Salary A/c is understated by ₹4,500. Cash A/c is correctly credited with ₹5,000.
Salary A/c Dr 4,500
To Suspense A/c 4,500
(Being salary account undercast by ₹4,500, now rectified)
Q2. Rectify the following errors (after preparing the trial balance):
Answer
(i) A purchase of goods ₹2,000 from Ravi was not recorded in the books (ii) Purchase of machinery ₹15,000 was recorded in the Purchases Book (iii) A cheque of ₹1,000 received from Deepa was dishonoured but not recorded (iv) Discount allowed ₹200 was not posted to the Discount Allowed A/c (v) Goods returned to supplier ₹500 were not recorded
Rectification Entries:
(i) Purchase of goods ₹2,000 from Ravi not recorded (error of omission):
Purchases A/c Dr 2,000
To Ravi A/c 2,000
(Being purchase from Ravi omitted, now recorded)
(ii) Purchase of machinery ₹15,000 recorded in Purchases Book (error of principle):
Machinery A/c Dr 15,000
To Purchases A/c 15,000
(Being purchase of machinery wrongly recorded in Purchases Book, now rectified)
(iii) Cheque ₹1,000 from Deepa dishonoured (omission):
Deepa A/c Dr 1,000
To Bank A/c 1,000
(Being cheque received from Deepa dishonoured, now recorded)
(iv) Discount allowed ₹200 not posted (one-sided error):
Discount Allowed A/c Dr 200
To Suspense A/c 200
(Being discount allowed not posted to Discount Allowed A/c, now rectified)
(v) Goods returned to supplier ₹500 not recorded (error of omission):
Supplier A/c Dr 500
To Purchase Returns A/c 500
(Being goods returned to supplier omitted, now recorded)
Q3. Explain the types of errors with examples.
Answer
1. Error of Omission: A transaction is completely omitted from the books. - Example: Purchase of goods from Ram for ₹5,000 not recorded at all. Neither the Purchases A/c nor Ram's A/c is affected.
2. Error of Partial Omission: One side of the transaction is recorded, but the other side is omitted. - Example: Cash received from Sita ₹3,000 is recorded in the Cash Book, but not posted to Sita's account.
3. Error of Commission: The transaction is recorded but with a wrong amount or in the wrong account (but on the correct side). - Example: Purchase of goods ₹5,000 from Kumar recorded as ₹500 in both accounts. Both sides are affected equally.
4. Error of Principle: A transaction is recorded in the wrong category — typically, a capital expenditure is treated as revenue expenditure or vice versa. - Example: Purchase of machinery ₹50,000 recorded as Purchase of goods ₹50,000.
5. Compensating Error: Two or more errors that cancel each other out. - Example: Purchases A/c overcast by ₹1,000 and Sales A/c also overcast by ₹1,000. The net effect is zero.
6. Error of Original Entry: The original record has a wrong amount, and this wrong amount is posted to both sides. - Example: Invoice for ₹5,000 recorded as ₹500 in the day book, and ₹500 posted to both Purchases A/c and Creditor's A/c.
Common Mistakes to Avoid
- Confusing error of omission and error of partial omission: Error of COMPLETE omission = not recorded at all = NOT disclosed by TB. Error of PARTIAL omission = one side recorded, other omitted = disclosed by TB.
- Using Suspense Account for two-sided errors: Suspense Account is used ONLY for one-sided errors. Two-sided errors are rectified by a correcting journal entry — no Suspense Account needed.
- Not identifying the type of error correctly: Before rectifying, always identify: (1) Is it one-sided or two-sided? (2) Is it before or after trial balance? (3) Which accounts are affected?
- Rectifying with wrong journal entry: For two-sided errors, debit the account that SHOULD have been debited and credit the account that SHOULD have been credited. Think: "What should the correct entry be?" Then compare with the wrong entry.
- Forgetting to close the Suspense Account: After rectifying all one-sided errors, the Suspense Account must have a zero balance. If it doesn't, there are still undiscovered errors.
- Treating error of principle as error of commission: Error of principle involves wrong CLASSIFICATION (capital vs revenue). Error of commission involves wrong AMOUNT or wrong ACCOUNT but same category.
