Bank Reconciliation Interview Questions & Answers

Q: What causes a bank reconciliation not to balance and how do you investigate?

Non-agreement can arise from omitted or duplicated cash book entries, transposed figures, missed statement items, incorrectly listed unpresented cheques/lodgements, or a bank error. Investigate by re-checking each reconciling item, agreeing individual cash book entries to the statement, verifying casts, and confirming the opening balances reconcile. Bank errors are queried with the bank.

Q: How does the bank reconciliation interact with the financial statements?

The adjusted cash book balance—after all updates—is the bank figure reported in the balance sheet under cash and cash equivalents (or as an overdraft under current liabilities). The reconciliation provides evidence the reported bank balance is accurate and complete, and any period-end reconciling items are properly reflected or disclosed.

Q: How often should bank reconciliations be performed?

Bank reconciliations should be performed regularly—commonly monthly, and more frequently (weekly or daily) for businesses with high transaction volumes or higher fraud risk. Frequent reconciliation catches errors and unauthorized transactions early and keeps the cash book accurate for decision-making and reporting.

Q: What is a direct debit and how does it appear in reconciliation?

A direct debit is an instruction letting a supplier collect variable or fixed amounts from the business's bank account. It often appears first on the bank statement, so it must be entered in the cash book (credit bank, debit the relevant expense/payable) during reconciliation.

Q: What is a standing order?

A standing order is a fixed, regular payment the bank makes from the account on the business's instruction (e.g., a loan repayment or rent). Like direct debits, it may appear on the statement before the cash book, requiring a cash book update during reconciliation.

Q: How do bank errors feature in a reconciliation?

Occasionally the bank makes an error (wrong amount, wrong account, duplicated entry). Such items are not corrected in the cash book; instead they're shown as reconciling items and queried with the bank, which issues an adjustment. The reconciliation notes them until the bank corrects its records.

Q: How do you reconcile when starting from the cash book balance instead of the statement?

You can reconcile in either direction. Starting from the (adjusted) cash book balance: add back unpresented cheques and deduct outstanding lodgements to arrive at the bank statement balance. The reconciling items are the same; only the direction of the adjustments reverses.

Q: How does the timing of banking affect month-end reconciliation?

Receipts banked at or after the last business day of the month are recorded in the cash book but may not reach the statement until the next month, creating outstanding lodgements. Similarly, cheques written near month-end remain unpresented. These timing items are the main reconciling differences and clear early next month.

Q: What is a credit transfer (bank giro) received?

A credit transfer is money paid directly into the business's bank account by a customer or third party (e.g., BACS/bank transfer). It may appear on the statement before being recorded, so the cash book is updated (debit bank, credit the customer/receivable or income) during reconciliation.

Q: What is the correct order: update the cash book first or reconcile the statement first?

Update the cash book first for all statement-only items (charges, interest, direct debits, standing orders, dishonoured cheques, transfers) and correct cash book errors to get the adjusted cash book balance. Then reconcile the bank statement balance to that adjusted figure using timing differences. Doing it in this order avoids double-counting.

What causes a bank reconciliation not to balance and how do you investigate?

Intermediate

Non-agreement can arise from omitted or duplicated cash book entries, transposed figures, missed statement items, incorrectly listed unpresented cheques/lodgements, or a bank error. Investigate by re-checking each reconciling item, agreeing individual cash book entries to the statement, verifying casts, and confirming the opening balances reconcile. Bank errors are queried with the bank.

Real-world example A stubborn difference is traced to a transposed cheque amount (£54 entered as £45) in the cash book.
