Which of the following is a reason for difference between cashbook and bank passbook balance?

All of these

The correct answer is option 4- All of these.

All are the reason for difference between cashbook and bank passbook balance.

Cheque deposited but not credited- When firm receives cheques from its customers (debtors), they are immediately recorded in the debit side of the cash book. This increases the bank balance as per the cash book. However, the bank credits the customer account only when the amount of cheques are actually realised. The clearing of cheques generally takes few days especially in case of outstation cheques or when the cheques are paid-in at a bank branch other than the one at which the account of the firm is maintained. This leads to a cause of difference between the bank balance shown by the cash book and the balance shown by the bank passbook

Cheque issued but not presented for payment- When cheques are issued by the firm to suppliers or creditors of the firm, these are immediately entered on the credit side of the cash book. However, the receiving party may not present the cheque to the bank for payment immediately. The bank will debit the firm’s account only when these cheques are actually paid by the bank. Hence, there is a time lag between the issue of a cheque and its presentation to the bank which may cause the difference between the two balances.

Interest collected by bank- When the bank collects interest on behalf of the customer, then these are immediately credited to the customers account. But the firm will know about these transactions and record the same in the cash book only when it receives a bank statement. Till then the balances as per the cash book and passbook will differ.
