Bank Reconciliation Statement: Cash Book vs Pass Book (JAIIB AFM)

Every JAIIB AFM paper carries marks on the bank reconciliation statement, and almost all of them are scoring marks — provided you know which way each item moves. A bank reconciliation statement is simply a working that explains why the bank balance in a firm's own cash book differs from the balance shown by the bank in the pass book or account statement on the same date. It is not a ledger account, it is not part of the final accounts, and it does not by itself correct anything. It is a bridge between two records that are both, in their own way, correct.

For a working banker this is daily life: the customer swears the balance is one figure, the CBS screen shows another, and the gap is almost always cheques in transit, charges, or a standing instruction nobody told the accountant about. This article walks through the causes, both directions of preparation, the treatment rules examiners test, and one full worked numerical with figures.

📘 Why the cash book and pass book disagree

The firm records bank transactions in the bank column of its cash book. The bank records the same relationship in its own books, from its own side. Two independent records of one relationship will only agree if both parties record every event at the same moment — which never happens.

The first reason is the mirror effect. The firm's cash book bank column is an asset account: money in the bank is a debit balance. In the bank's books the customer is a creditor, so the same money is a credit balance in the pass book. A favourable balance is therefore a debit in the cash book and a credit in the pass book. If you are shaky on debit-credit direction, revise basic accountancy procedures before attempting reconciliation sums, because every BRS mistake in the exam traces back to sign confusion.

The second reason is lag. The firm records a cheque when it writes it; the bank records it when the payee presents it. The firm records a deposit when it drops the cheque in; the bank records it when clearing completes.

The third reason is one-sided knowledge. The bank knows about charges, interest, direct credits and standing instructions before the customer does. Those entries sit in the pass book for days before the accountant sees the statement.

The fourth reason is plain error — by the firm, by the bank, or by both.

🔍 Timing differences versus errors

Every item that goes into a bank reconciliation statement belongs to one of two families, and the family decides the treatment.

Timing differences

Both books are correct; only the dates differ. These items need no entry anywhere — they self-correct when the transaction completes. Typical items:

• Cheques issued but not yet presented for payment (unpresented cheques)
• Cheques deposited but not yet credited or cleared (uncredited cheques)
• Deposits made after banking hours or in a drop box on the last day
• Bills sent for collection, credited by the bank only on realisation

Items known only to the bank

The bank has already passed the entry; the firm has not. These are not pure timing differences — once the firm learns of them it must pass a real entry in the cash book. Bank charges, commission, interest debited on an overdraft, interest allowed on balances, direct credits by NEFT/RTGS/UPI, dividends collected, standing instructions executed and cheques returned dishonoured all sit here.

Errors

Errors need correction in whichever set of books contains them. A cheque entered twice in the cash book, a wrong casting of the bank column, a deposit slip totalled wrongly, or a debit wrongly raised by the bank in another customer's account — each is corrected at source, and only the uncorrected portion appears in the statement.

💡 Exam Tip: Ask one question of every item — "does my cash book need a fresh entry?" If yes, it is a bank-side item or an error, not a timing difference. That single test resolves most JAIIB AFM reconciliation questions faster than memorising add/less lists.

🧾 Preparing a bank reconciliation statement step by step

A bank reconciliation statement can be prepared in either direction, and JAIIB AFM asks for both. The method never changes: start from one balance, ask what the other book has that this one does not, and adjust.

Direction A — from cash book to pass book

1. Write the starting line: "Balance as per cash book (Dr.) — Rs …". If it is an overdraft, write it as a negative figure and carry the sign through.
2. Add every item that makes the bank balance higher than the cash book: cheques issued but not presented, direct credits, interest allowed by the bank, bills collected.
3. Deduct every item that makes the bank balance lower: cheques deposited but not credited, bank charges and commission, overdraft interest, standing instructions executed, cheques dishonoured, wrong debits by the bank.
4. The closing line is the balance as per pass book.

Direction B — from pass book to cash book

Reverse every sign. What was added now gets deducted and vice versa. If your Direction B answer does not return you to the Direction A starting figure, you have mis-signed an item.

The adjusted (amended) cash book route

Better practice — and what banks actually do — is a two-stage approach. First pass entries in the cash book for everything the bank already knows: charges, interest, direct credits, standing instructions, dishonours. That gives an adjusted cash book balance. Then reconcile only the genuine timing differences. This is also the balance that flows into the bank column of the balance sheet, which matters when you study final accounts of banking companies and when preparing the cash-and-cash-equivalents line under cash flow statement rules.

🧮 Worked numerical: reconciling on 31 March 2026

Shreyas Traders' cash book shows a debit (favourable) bank balance of Rs 1,86,400 on 31 March 2026. On comparing with the pass book:

• Cheques issued but not presented up to 31 March: Rs 42,300
• Cheques deposited but not credited by the bank: Rs 61,500
• Bank charges and commission debited by the bank: Rs 1,850
• Amount received by NEFT from a customer, credited directly: Rs 24,000
• Insurance premium paid by the bank under standing instruction: Rs 12,500
• Interest allowed by the bank on balances: Rs 3,200
• A cheque of Rs 9,000 deposited earlier was returned dishonoured; no entry made

Statement — Direction A

Balance as per cash book (Dr.): Rs 1,86,400
Add: unpresented cheques Rs 42,300 → Rs 2,28,700
Less: uncredited cheques Rs 61,500 → Rs 1,67,200
Less: bank charges Rs 1,850 → Rs 1,65,350
Add: NEFT direct credit Rs 24,000 → Rs 1,89,350
Less: insurance premium (standing instruction) Rs 12,500 → Rs 1,76,850
Add: interest allowed Rs 3,200 → Rs 1,80,050
Less: cheque dishonoured Rs 9,000 → Rs 1,71,050

Balance as per pass book (Cr.) = Rs 1,71,050.

Cross-check via the adjusted cash book

Pass entries for the five bank-side items: −1,850 + 24,000 − 12,500 + 3,200 − 9,000 = + Rs 3,850. Adjusted cash book balance = 1,86,400 + 3,850 = Rs 1,90,250. Now reconcile only the timing items: 1,90,250 + 42,300 − 61,500 = Rs 1,71,050. Both routes agree, which is your proof the working is sound.

⚠️ Common Mistake: Treating a dishonoured cheque as a timing difference. The bank has already reversed the credit; the firm has not. It must be deducted and entered in the cash book by debiting the debtor again.

⚠️ Overdrafts, charges and the items candidates fumble

Overdraft questions are where marks leak. When the cash book shows an overdraft, the bank column has a credit balance and the pass book shows a debit. The safest technique is to treat the overdraft as a negative figure — say (Rs 50,000) — and apply exactly the same add/less rules as a favourable balance. Cheques deposited but not credited of Rs 12,000 then give (50,000) − 12,000 = (62,000), i.e. an overdraft of Rs 62,000 as per pass book. No separate rule to memorise.

Three more items deserve attention:

• Bank charges and commission are an expense of the period, not a reconciling item to be carried forward indefinitely. They must be debited to a charges account, exactly as periodic write-offs are handled under depreciation accounting.
• Standing instructions — insurance premiums, EMIs, SIPs, utility bills — execute silently. Confirm the mandate list at each period end rather than waiting for the statement.
• Direct credits from NEFT, RTGS and UPI now dominate reconciliation lists at branch level, and unidentified credits are a suspense-account risk if left unallocated.

Do also confirm cut-off discipline: a cheque dated 31 March but handed over on 2 April is not a 31 March transaction at all, and forcing it into the reconciliation misstates the balance sheet. The same discipline that governs instalment cut-offs in hire purchase accounting entries applies here.

📌 Remember: A bank reconciliation statement never appears in the trial balance. Only the adjusted cash book balance does. Reconciliation is a control document, not a book of account.

Reconciliation is also a fraud control. Long-outstanding unpresented cheques, repeated wrong debits, or credits that never match a customer are classic early warnings — the same monitoring instinct you apply in budgetary control in banks. For firm-level capital accounts the parallel discipline shows up in accounting for goodwill in partnership firms, and at the macro level the same reconciliation logic underpins national income accounting in India, where output, income and expenditure estimates must tie back to one another.

📌 Before the exam: treat the bank reconciliation statement as a reasoning exercise, not a format to memorise. Decide first whether an item has been recorded by the bank, by the business, or by neither, and the direction of every adjustment follows. Branch staff meet the same logic in inter-branch and nostro reconciliation, where the Reserve Bank of India expects unreconciled entries to be aged and cleared within the bank's board-approved timelines. A candidate who can build a bank reconciliation statement from either starting point, and explain why an unpresented cheque and an uncredited cheque pull the balance in opposite directions, will not lose marks on this topic.
