Q.What is a bank reconciliation statement. Why is it prepared?

Bank Reconciliation Statement starting from Overdraft as per Pass Book, arriving at a favourable Cash Book balance of Rs. 2,040.

Bank Reconciliation Statement as on 31st December, 2025

Explanation of each item:

• Cheque deposited but uncollected (Rs. 8,560): already increases the Cash Book's bank balance (reduces its overdraft), but the Pass Book has not yet given credit for it — so the Cash Book shows a smaller overdraft (i.e., add back to the Pass Book overdraft figure).
• Incidental charges (Rs. 80): already reduces the Pass Book balance (increases overdraft), but not yet recorded in the Cash Book — so the Cash Book shows a smaller overdraft here too (add back).
• Cheques issued but unpresented (Rs. 3,400 = 7,800 − 4,400): the Cash Book has already deducted the full Rs. 7,800 (a bigger overdraft), while the Pass Book reflects only the Rs. 4,400 actually paid out — so the Cash Book overdraft is larger by Rs. 3,400 (deduct, i.e. reduce the favourable adjustment).
• Insurance premium paid by bank (Rs. 4,200): already reduces the Pass Book balance (bigger overdraft there), not yet in the Cash Book — so the Cash Book overdraft is smaller by this amount (add back).
• Cashier's error (Rs. 200 = 485 − 285): the Cash Book (as actually written up) recorded Rs. 200 more than the actual amount deposited, so it shows Rs. 200 less overdraft than it correctly should relative to the Pass Book's correct figure (add back).

Result: Balance as per Cash Book = Rs. 13,040 − Rs. 11,000 = Rs. 2,040, a favourable (debit) balance — i.e., despite the Pass Book showing an overdraft, the correctly adjusted Cash Book actually shows a small positive bank balance of Rs. 2,040.

Starting from the Pass Book balance of Rs. 1,575: add the uncleared deposited cheque (Rs. 580), deduct the unpresented issued cheques (Rs. 640) and the bank-credited interest not yet recorded in the cash book (Rs. 25) — arriving exactly at the Cash Book balance of Rs. 1,490.

Analysing each item:

1. Cheque deposited Rs. 580, not yet cleared — this has already been recorded as a receipt in the Cash Book (debited), but the bank has not yet collected/credited it in the Pass Book. So the Pass Book balance is understated relative to the Cash Book by this amount — it must be added to the Pass Book balance to reconcile to the Cash Book figure.
2. Cheques issued Rs. 960 on 18th August, of which Rs. 640 not presented till 3rd September — the unpresented portion, Rs. 640, has already been recorded as a payment in the Cash Book (credited), reducing the Cash Book balance, but the bank has not yet deducted it from the Pass Book (since the payee hasn't encashed it yet). So the Pass Book balance is overstated relative to the Cash Book by this amount — it must be deducted from the Pass Book balance.
3. Interest of Rs. 25 credited by the bank (Pass Book), not yet entered in Cash Book — the bank has already added this to the Pass Book balance, but the firm has not yet recorded it in its own Cash Book. So the Pass Book balance is overstated relative to the Cash Book by this amount — it must be deducted from the Pass Book balance. Bank Reconciliation Statement as on 31st August, 2023 (starting from Pass Book balance):

Calculation: 1,575 + 580 − 640 − 25 = 1,490, which exactly matches the given Cash Book balance, confirming the reconciliation is correct.

A Bank Reconciliation Statement (BRS) is prepared to reconcile the balance shown by the Cash Book with the balance shown by the Bank Passbook, mainly to identify timing differences and genuine errors.

Main purposes of preparing a Bank Reconciliation Statement:

1. To identify the causes of difference between the balance as per Cash Book and the balance as per Pass Book on a given date (e.g., cheques issued but not yet presented, cheques deposited but not yet collected, bank charges/interest not yet recorded in the cash book, direct deposits/withdrawals by the bank not yet recorded by the firm).
2. To detect errors committed either by the business (in the Cash Book) or by the bank (in the Pass Book), such as wrong amount recorded, wrong account debited/credited, or a transaction omitted entirely.
3. To ensure accuracy and reliability of the cash/bank balance reported in the Balance Sheet, so that the figure represents the true bank balance of the business.
4. To act as an internal control / check against fraud, since regular reconciliation helps detect unauthorised withdrawals or misappropriation of funds.
5. To keep track of uncleared cheques (issued or deposited) so that the firm's own cash planning is accurate.

OR — Four errors disclosed by the Trial Balance (explained briefly):

A Trial Balance will fail to agree (and thus 'disclose' that an error exists) whenever an error affects only one side/one account of the double entry. Examples:

1. Error of Partial Omission (one-sided omission): An amount is posted to one account (say the Journal) but omitted from being posted to the other (ledger) account — e.g., a sale is recorded in the Sales Book but never posted to the Customer's personal account. This leaves one side short, so the Trial Balance will not tally.
2. Error of posting to the wrong side of an account: An amount that should be debited is instead posted to the credit side of the same (or another) account, e.g., Rs. 500 received from a customer is wrongly entered on the debit side of his account instead of the credit side — this error doubles the apparent discrepancy and the Trial Balance will disagree.
3. Error of Casting (overcasting/undercasting) a subsidiary book: If a subsidiary book's total (e.g. Purchases Book, Sales Book) is wrongly added (totaled too high or too low), the ledger account to which this total is posted will carry the wrong balance, causing the Trial Balance to disagree.
4. Error of posting a wrong amount to one side of a ledger account: For example, Rs. 1,000 is correctly entered in the Cash Book but wrongly posted as Rs. 100 (or Rs. 10,000) to the ledger account — since only one account is affected incorrectly, the Trial Balance totals will not match.

(All of the above are one-sided errors — they disturb the equality of total debits and total credits, and are therefore automatically 'disclosed' by a disagreeing Trial Balance, unlike two-sided errors such as Errors of Principle or Compensating Errors, which leave the Trial Balance unaffected.)

Bank Reconciliation Statement (starting from the Cash Book balance): Pass Book balance = Rs. 86,800.

Bank Reconciliation Statement as on the given date

(starting with the balance as per Cash Book)

Reasoning: cheques issued but not presented have already reduced the Cash Book's bank balance, but the bank hasn't deducted them yet, so the Pass Book shows a higher figure — hence added. Cheques deposited but not yet credited have already been added in the Cash Book, but the bank hasn't credited them yet, so the Pass Book shows a lower figure — hence deducted. Bank charges have already been deducted by the bank (lowering the Pass Book balance) but not yet entered in the Cash Book — hence also deducted while moving from the Cash Book to the Pass Book balance.
