Bank Reconciliation Statement: Practical BRS Guide with Example and Month-End Checklist

A bank reconciliation statement (BRS) explains why the bank balance in an entity's cash book does not match the balance shown by the bank statement on the same date. The difference is often caused by timing rather than an accounting error: a cheque may have been issued but not yet presented, or a deposit may have been recorded by the business but not yet cleared by the bank.

For accountants, a BRS is more than an exam-format statement. It is a control over cash, a way to identify missing entries and unusual transactions, and an important month-end close procedure. ICAI's Foundation Accounting study-material index includes Bank Reconciliation Statement as a dedicated accounting chapter, and the ICAI Board of Studies chapter page provides the corresponding study resource.

Why cash book and bank statement balances differ

The cash book records bank transactions from the business's perspective. The bank statement records the same account from the bank's perspective. The two records may be correct and still show different balances at a particular date because an entry can reach one record before it reaches the other.

The most common reconciling items are cheques issued but not yet presented, cheques deposited but not yet credited, bank charges or interest entered by the bank before the business records them, direct deposits by customers, standing instructions, dishonoured cheques, and errors in either record. ICAI's Bank Reconciliation Statement learning material groups these causes into items recorded in one book but not the other and errors requiring correction.

Timing difference or accounting error?

This distinction is the key to preparing a useful BRS. A timing difference does not necessarily require a journal entry. If the business has correctly recorded a cheque issued to a supplier but the supplier has not presented it, the cash book is already correct. The item remains in the reconciliation until it clears.

An item appearing only in the bank statement may require the cash book to be updated. Bank charges are a simple example. If the bank has debited charges but the business has not recorded them, the books are incomplete. The accountant should post the appropriate entry and then reconcile the adjusted cash-book balance.

An actual error should be investigated rather than permanently carried as a reconciling item. A duplicate payment, an incorrect amount, or a transaction belonging to another bank account needs correction and supporting evidence.

A practical step-by-step BRS process

1. Fix one reconciliation date. Obtain the cash-book or general-ledger bank balance and the bank statement ending on the same date.
2. Match transactions. Tick deposits and withdrawals that appear in both records. Matching should consider amount, date, reference and counterparty where available.
3. List unmatched cash-book entries. These commonly include deposits in transit and cheques or payments not yet presented or processed by the bank.
4. List unmatched bank entries. Look for bank charges, interest, direct credits, standing instructions, automatic debits, reversals and dishonoured receipts that have not reached the books.
5. Post book corrections. Record genuine bank-side items and correct cash-book errors before treating them as reconciliation differences.
6. Investigate bank errors or unknown items. Do not force the reconciliation by posting an unexplained suspense entry merely to make the balances agree.
7. Prepare the final reconciliation. Starting from one corrected balance, add and subtract valid timing items until the other balance is reached.
8. Review old outstanding items. Long-outstanding cheques, deposits or unexplained debits deserve escalation even if the arithmetic reconciles.

Worked example

Assume the adjusted cash book shows a favourable bank balance of Rs. 1,20,000 on 31 March. Two cheques totalling Rs. 25,000 have been issued and recorded in the cash book but have not yet been presented. A customer deposit of Rs. 10,000 has been recorded in the cash book but is still awaiting bank credit.

Starting with Rs. 1,20,000, add Rs. 25,000 for cheques issued but not presented because the bank has not yet reduced its balance. Then subtract Rs. 10,000 for the deposit not yet credited because the bank has not yet increased its balance. The reconciled bank-statement balance is therefore Rs. 1,35,000.

Now assume the bank statement also shows Rs. 500 of bank charges not yet recorded in the books. That Rs. 500 is not merely a timing difference to carry indefinitely. The cash book should first be updated for the charge. The BRS should then be prepared from the corrected cash-book balance.

Adjusted cash book versus BRS

An adjusted cash book updates the business's own records for entries that should already have been recorded there. The BRS then explains the remaining legitimate difference between the corrected books and the bank's record.

This sequence prevents a common mistake: mixing missing book entries with genuine timing differences. Bank charges, direct credits and similar known bank-originated items generally belong in the books once identified. Cheques that are correctly recorded but still in transit normally remain reconciliation items until cleared.

Why monthly reconciliation is an important control

A regular BRS can reveal duplicate payments, unauthorised withdrawals, stale cheques, missed receipts, wrong bank postings and bookkeeping omissions. It also improves the reliability of the cash figure used in management accounts and financial statements.

Frequency should reflect transaction volume and risk. A low-volume account may be reconciled monthly, while a high-volume collection or payment account may need more frequent monitoring. Whatever the frequency, the process should have a clear preparer, reviewer, completion date and evidence of follow-up on exceptions.

Common mistakes to avoid

• Using different cut-off dates: both records must be compared at the same reconciliation date.
• Treating every difference as timing: some differences require a book entry or investigation.
• Ignoring old reconciling items: a BRS can mathematically agree while hiding stale or suspicious transactions.
• Posting a suspense amount to force agreement: reconciliation is meant to explain the difference, not conceal it.
• Confusing favourable and overdraft balances: the direction of additions and deductions changes with the starting balance and record used.
• Skipping independent review: reconciliation is a stronger control when unusual and aged items are reviewed by someone with appropriate authority.

Month-end BRS checklist

• Use the correct bank account and identical cut-off date.
• Reconcile the opening position with the prior month's approved BRS.
• Match all material receipts and payments.
• Post bank charges, interest, direct credits and other missing book entries.
• Investigate unidentified or duplicate transactions.
• Age outstanding cheques and deposits rather than rolling them forward blindly.
• Attach the bank statement, ledger extract and supporting explanations.
• Obtain reviewer sign-off and track unresolved items to closure.

Practical takeaway

A good bank reconciliation does three things: it corrects the books where necessary, explains genuine timing differences, and highlights items that need investigation. The objective is not simply to make two balances agree. It is to establish that the recorded bank balance is complete, supportable and free from unexplained differences. For students and professionals who want the underlying accounting treatment, ICAI's official BRS learning material provides examples of the standard reconciliation logic.
