Trial Balance, Rectification of Errors and Adjusting & Closing Entries
(Does Your Trial Balance Tally? And What If It Doesn’t?)
You’ve passed all journal entries and posted them to the ledger. Now it’s time to CHECK if everything is correct. How? Add up all debits and all credits. If they’re equal — great! If not — there’s an error somewhere. This chapter teaches you how to find those errors, fix them, and close the books.
Banky’s Numbers Don’t Add Up! 😰
Banky prepared a Trial Balance at month-end. Total debits = ₹15,73,000. Total credits = ₹15,68,000. There’s a difference of ₹5,000! His manager says: “Find the error!” Banky says: “But there are HUNDREDS of entries! Where do I even start looking?”
Why is This Important?
Trial Balance is the HEALTH CHECK of your entire accounting
Exam Marks
4–6 questions! Types of errors, which errors affect/don’t affect TB, suspense account, rectification entries. Very high scoring!
Bank Work
Every branch balances books daily. When CBS shows a difference, you need to trace and rectify. This is YOUR job as an officer!
Life Skill
Even checking your monthly expenses — if total spending doesn’t match total withdrawals, you look for the missing receipt. Same logic!

Key Words — Everyday Language
After posting all entries from the journal to the ledger and balancing every account, you make a simple list: write down every account name, its debit balance, and its credit balance. Add up all debit balances. Add up all credit balances. If total debits = total credits, your books are ARITHMETICALLY correct. If they DON’T match, there’s a mistake somewhere.
6 features: (1) It’s a list of debit and credit balances drawn from the ledger. (2) It includes cash and bank balances. (3) Its main purpose is to check arithmetical accuracy. (4) Usually prepared at year-end, but can be prepared monthly/quarterly too. (5) Shows amounts receivable and payable. (6) Helps in preparing final accounts (P&L and Balance Sheet).
2 Types: Gross Trial Balance = lists TOTAL debits and TOTAL credits of each account (before balancing). Net Trial Balance = lists only the NET BALANCE (debit or credit) of each account.
Complete Omission: You bought goods from Mr. A on credit — but completely forgot to record it ANYWHERE. Neither in the journal nor in the ledger. Since BOTH debit and credit are missing, the Trial Balance still tallies! But the books are WRONG.
Partial Omission: You recorded the purchase in the journal but FORGOT to post it to Mr. A’s account in the ledger. Now one side is recorded, the other isn’t. The Trial Balance will NOT tally.
Key point: Complete omission does NOT affect Trial Balance. Partial omission DOES affect it.
You made the entry, but made a mistake while doing it. Five common types:
(1) Correct amount but posted to the WRONG side (debit instead of credit). (2) Wrong AMOUNT posted but on the correct side (₹720 posted as ₹270). (3) Wrong amount on wrong side (double trouble!). (4) Totaling error in any subsidiary book. (5) Balancing mistake in a ledger account.
These errors AFFECT the Trial Balance because one side has the wrong number. Example: Sale of ₹720 to Sanjay posted as ₹270 — the difference of ₹450 will make the Trial Balance not tally.
Rent account is UNDERCAST (totaled less) by ₹1,000. At the same time, Stationery account is OVERCAST (totaled more) by ₹1,000. These two mistakes cancel each other out! The Trial Balance tallies, but BOTH accounts show wrong amounts.
These errors do NOT affect the Trial Balance — because the mistakes compensate each other.
You paid ₹500 wages for installing a new machine. The CORRECT entry: Debit Machinery A/c (it’s a capital expenditure that increases the machine’s value). But you wrongly debited Wages A/c (treated it as a regular expense). Both are debits — so the Trial Balance still tallies! But the Machinery account shows LESS and Wages shows MORE than it should.
These errors do NOT affect the Trial Balance — because total debits still equal total credits. But the NATURE of the entry is wrong.
If your Trial Balance doesn’t tally and you CAN’T find the error immediately, you put the difference in a temporary account called Suspense Account. This makes the Trial Balance tally (for now) so you can prepare the final accounts. As you find and fix each error, you clear the Suspense Account. When ALL errors are found, the Suspense Account balance becomes ZERO.
One-sided errors: Affect only ONE account — fix by passing entry with Suspense Account. Two-sided errors: Affect TWO accounts — fix by writing the correct entry, comparing with the wrong entry, and passing a rectification entry.
Adjusting Entries: At year-end, some expenses are incurred but not yet paid (outstanding salary), some are paid in advance (prepaid insurance), some income is earned but not received (accrued interest). These entries ADJUST the books to show the TRUE picture. Without them, the P&L and Balance Sheet would be incomplete.
Closing Entries: At year-end, all expense and income accounts (Nominal accounts) are CLOSED — their balances are transferred to the Trading Account and P&L Account. This resets them to zero for the next year. Real and Personal accounts are NOT closed — they carry forward to the next year.
The Full Chapter — Simple Story
📖 Part 1 — The Error Family Tree
All errors in accounting belong to two big families:
Family 1 — Clerical Errors (mistakes in writing/calculating): Three children: (a) Errors of Omission — forgot to record. Complete omission (both sides missing) → TB tallies. Partial omission (one side missing) → TB doesn’t tally. (b) Errors of Commission — recorded but wrong amount/side/account. → TB usually doesn’t tally. (c) Compensating Errors — two mistakes cancel out. → TB tallies but individual accounts wrong.
Family 2 — Errors of Principle (put in wrong TYPE of account): Capital expense treated as revenue, or vice versa. Example: Machine installation wages in Wages A/c instead of Machinery A/c. → TB tallies but accounts are wrongly classified.
Quick Rule: Which errors DON’T affect Trial Balance? Three types: (1) Complete Omission, (2) Compensating Errors, (3) Errors of Principle. Only Partial Omission and Errors of Commission cause the Trial Balance to NOT tally.
🔍 Part 2 — How to FIND Errors (Location)
If your Trial Balance doesn’t tally, here’s how to find the error step by step:
Step 1: Re-add the debit and credit columns. Simple calculation mistake?
Step 2: Check if cash and bank balances are correctly shown.
Step 3: Find the EXACT difference amount. Say debit is ₹1,600 more. Then: (a) Check if ₹1,600 appears twice on the debit side. (b) Take HALF the difference (₹800) — maybe an item of ₹800 is on the debit side instead of credit side (which would cause a ₹1,600 difference). (c) Check if a credit item of ₹1,600 was omitted from the Trial Balance.
Step 4: Check all postings from journal to ledger — correct amounts? Correct sides?
Step 5: Check balancing of all ledger accounts.
🔧 Part 3 — How to FIX Errors (Rectification)
One-sided Errors (only ONE account is wrong): Just correct that one account. If Suresh was wrongly debited ₹200 instead of credited, credit Suresh ₹400 (₹200 to cancel the wrong debit + ₹200 for the correct credit). If the Trial Balance is already prepared, use Suspense Account on the other side.
Two-sided Errors (TWO accounts are affected): Write the CORRECT entry. Then write the WRONG entry that was passed. Compare them. The difference = rectification entry. Example: Goods purchased from Sohanlal wrongly recorded in Sales Register — both Purchases A/c and Sales A/c need correction, plus Sohanlal’s account.
When error is posted to WRONG SIDE: Rectification amount = DOUBLE the original amount. Example: ₹200 posted to debit instead of credit → difference is ₹400, so correct with ₹400 on the right side.
📅 Part 4 — Adjusting & Closing Entries
Adjusting Entries = entries passed at year-end to account for things not yet recorded. Examples: Outstanding salary (expense incurred but not paid), Prepaid insurance (paid but belongs to next year), Accrued interest (earned but not received). Without these, the P&L and Balance Sheet won’t show the TRUE picture.
Closing Entries = entries to transfer ALL nominal account balances (expenses & incomes) to Trading A/c and P&L A/c. After closing entries, all nominal accounts have ZERO balance. Real and Personal accounts carry forward to next year through the Opening Entry.
Sequence: Ledger → Balance all accounts → Trial Balance → Adjusting Entries → Final Accounts (Trading, P&L, Balance Sheet) → Closing Entries → Opening Entry for next year.

- 6 Features: List of balances, includes cash/bank, checks accuracy, prepared at year-end (or any time), shows receivables/payables, helps prepare final accounts.
- 2 Types: Gross TB (total debits & credits before balancing) | Net TB (only net balances)
- Errors of Omission: Complete = both sides missed → TB tallies. Partial = one side missed → TB doesn’t tally.
- Errors of Commission: Wrong amount, wrong side, wrong account → TB usually doesn’t tally.
- Compensating Errors: Two errors cancel out → TB tallies but individual accounts wrong.
- Errors of Principle: Wrong TYPE of account (capital vs revenue) → TB tallies but wrong classification.
- Errors that DON’T affect TB: Complete Omission, Compensating, Principle — “CCP don’t care about TB!”
- Errors that AFFECT TB: Partial Omission and Commission — “PC affects TB!”
- Suspense Account: Temporary account for the difference when TB doesn’t tally. Cleared when all errors found.
- One-sided error: Only one account wrong. Use Suspense A/c on the other side for rectification.
- Two-sided error: Two accounts wrong. Write correct entry, compare with wrong entry, pass rectification.
- Wrong side error: Rectification = DOUBLE the original amount (cancel + correct).
- Credit sale of X posted to credit of customer: Rectification = Debit customer 2X (since customer should be debited X, but was credited X → difference = 2X)
- Freight for machinery carried to Travel A/c: Rectification = Debit Machinery A/c, Credit Travel A/c (error of principle)
- Goods sold to Vijay entered in Purchase A/c: Credit Purchases + Credit Sales each X, Debit Vijay.
- Adjusting Entries: Year-end entries for outstanding expenses, prepaid expenses, accrued income, income received in advance.
- Closing Entries: Transfer ALL nominal accounts to Trading/P&L A/c. Nominal accounts become zero.
- Goods sold on credit not recorded in books → will NOT affect Trial Balance (complete omission)
