Bank Reconciliation Statement
(Why Don’t Your Cash Book and Passbook Match?)
You wrote ₹50,000 as your bank balance in your cash book. But the bank’s passbook shows ₹47,000. Who’s right? BOTH are right — they just recorded things at different times! This chapter teaches you how to find the differences and bring them together. That process is called Bank Reconciliation.
Banky’s Cash Book Doesn’t Match! 😱
Banky checked his branch’s bank column in the cash book — it says ₹5,00,000. He then checked the bank statement (passbook) — it says ₹4,85,000. ₹15,000 difference! His manager says: “Don’t worry, prepare a BRS.” Banky says: “BRS? Is that a new scheme?”
Why Should You Learn This?
Because you’ll prepare BRS every single month at the bank!
Exam Marks
3–5 questions! Reasons for difference, mirror image concept, BRS format, favourable vs overdrawn balance. Very scoring!
Daily Work
Every month-end, every branch prepares BRS. Audit and inspection teams check it. This is your CORE banking skill.
Personal Life
Even your personal bank statement might not match your records. Same logic applies — cheques pending, auto-debits you forgot!
Real Bank Scenario
What Will You Learn?
Key Words — Simple as Chai ☕
Your business keeps a Cash Book with a bank column — this is YOUR record of what you deposited and withdrew. The bank keeps a Passbook (or bank statement) — this is the BANK’S record of what happened in your account. Both should show the same balance, right? But they often DON’T — because some things are recorded at different times. The BRS is a detective report that finds every difference and explains it.
When you deposit ₹10,000 in the bank, you DEBIT the bank column (bank received money). But in the bank’s books, they CREDIT your account (they owe you more money now). So your DEBIT = bank’s CREDIT. Your CREDIT = bank’s DEBIT. It’s like looking in a mirror — left becomes right!
Important: Your cash book debit balance (you have money in bank) = passbook credit balance (bank owes you). If you have an overdraft (you owe the bank), then your cash book shows credit balance = passbook shows debit balance.
You write a cheque of ₹5,000 to your supplier on 25th March. You IMMEDIATELY record it in your cash book (credit bank column — money going out). But your supplier goes to the bank on 2nd April to cash it. Until then, the bank doesn’t know about this cheque! So on 31st March, your cash book shows ₹5,000 LESS than the passbook.
Effect: Cash book balance < Passbook balance. This entry is in cash book but NOT YET in passbook. No change needed in cash book — just wait for the cheque to be presented.
A customer gives you a cheque for ₹20,000 on 28th March. You deposit it in your bank and IMMEDIATELY record it in your cash book (debit bank column — money coming in). But the bank takes 3–4 days to clear the cheque through the clearing house. So on 31st March, the bank hasn’t yet added this ₹20,000 to your account.
Effect: Cash book balance > Passbook balance. This entry is in cash book but NOT YET in passbook. No change needed — just wait for clearing.
Sometimes the bank does things in your account that you find out ONLY when you check the passbook:
(a) Bank Charges: Cheque book charges, locker rent, SMS charges — bank deducted these, you didn’t know yet.
(b) Interest on Savings: Bank added interest to your account — nice surprise, but you didn’t record it yet!
(c) Interest on Overdraft: If you have an OD facility, bank charges interest — recorded in passbook, not yet in your cash book.
(d) Standing Instructions — Collections: Your bank collects dividends, interest on investments on your behalf and credits your account.
(e) Standing Instructions — Payments: Bank pays your insurance premium, loan EMI automatically on fixed dates.
(f) Direct Deposits by Customers: A customer deposits money directly into your bank account — bank knows, you don’t (until you check).
(g) Cheque Dishonour: A cheque you deposited bounced — bank debits your account, you find out later.
All these require you to UPDATE your cash book once you discover them.
The Full Chapter — As a Simple Story
📖 Part 1 — Why Do Cash Book and Passbook Differ? (3 Categories)
There are exactly 3 categories of reasons why your cash book and passbook show different balances:
Category 1 — ERRORS: Simple mistakes by you or the bank. Wrong amount written, entry in wrong column, calculation errors. These happen in both cash book and passbook. In a computerised system, clerical errors are very rare.
Category 2 — Entries in Cash Book but NOT YET in Passbook: These DON’T require any change in your cash book. You already recorded them correctly — the bank just hasn’t caught up yet. Two main cases: (a) Cheques you ISSUED but the other person hasn’t presented them to the bank yet. (b) Cheques you DEPOSITED but the bank hasn’t cleared them yet (takes 3–4 days).
Category 3 — Entries in Passbook but NOT YET in Cash Book: These REQUIRE you to update your cash book! The bank already processed these, but you didn’t know about them. Examples: bank charges, interest added, standing instruction payments, direct deposits by customers, cheque bouncing.
📋 Part 2 — How to Prepare BRS (The Format)
The BRS has TWO parts that should give the SAME final answer:
Part A — Adjust the Bank Statement: Start with closing balance per bank statement. ADD cheques deposited but not yet credited. SUBTRACT cheques issued but not yet presented. Result = Adjusted Bank Balance (A).
Part B — Adjust the Cash Book: Start with balance per cash book. ADD or SUBTRACT clerical errors. ADD credit entries in passbook not in cash book (interest received, direct deposits). SUBTRACT debit entries in passbook not in cash book (bank charges, standing instruction payments, cheque dishonour). Result = Adjusted Cash Book Balance (B).
If A = B → Reconciliation is complete! The adjusted bank balance equals the adjusted cash book balance. This adjusted balance is what goes into the Trial Balance and Balance Sheet.
⭐ Part 3 — 5 Advantages of BRS
1. Checks accuracy — confirms that entries in the cash book are correct by comparing with bank records.
2. Detects errors — finds mistakes in either cash book or passbook and helps correct them quickly.
3. Management control — a very important tool for managers to monitor cash and bank balances.
4. Shows correct balance — reveals the TRUE bank balance at any point in time.
5. Catches fraud — if someone is mishandling cash or cheques, BRS will reveal the discrepancies.
Exam-Ready Points
🎯 Must Remember!
- BRS = Statement that explains differences between cash book (bank column) and bank passbook/statement
- Mirror Image: Debit in cash book = Credit in passbook and vice versa. They are OPPOSITE reflections.
- Favourable balance: Cash book debit balance = Passbook credit balance (you HAVE money in bank)
- Overdrawn balance: Cash book credit balance = Passbook debit balance (you OWE the bank)
- Bank statement = copy of customer’s account in the BANK’S books (not cash book!)
- Cheques issued but not presented: In cash book, NOT yet in passbook. Cash book < Passbook. No change needed in cash book.
- Cheques deposited but not collected: In cash book, NOT yet in passbook. Cash book > Passbook. No change needed.
- Bank charges, OD interest: In passbook, NOT yet in cash book. Cash book needs to be UPDATED (credit bank column).
- Interest on savings: In passbook, NOT yet in cash book. Cash book needs to be UPDATED (debit bank column).
- Direct deposit by customer: In passbook, NOT yet in cash book. Passbook > Cash book. Update cash book (debit).
- Cheque dishonour: In passbook (bank debited), NOT yet in cash book. Update cash book (credit bank column).
- Standing instructions — collection: Bank collects dividend/interest on your behalf. In passbook, not cash book. Update cash book (debit).
- Standing instructions — payment: Bank pays insurance/EMI on your behalf. In passbook, not cash book. Update cash book (credit).
- Adjusted bank balance (A) must equal Adjusted cash book balance (B)
- 5 Advantages: Accuracy check, error detection, management control, shows correct balance, fraud detection
- BRS is NOT prepared by the bank — it’s prepared by the TRADER/BUSINESS
- Overcasting receipts side of cash book: Cash book shows MORE than actual → decreases cash book balance to reconcile
- Debit balance in bank statement = overdraft = credit balance in cash book
- Credit balance carried forward on DEBIT side of cash book = reconciliation is casting x on credit side
