Bank Statements and Bank Reconciliation: Complete Guide

Last reviewed: July 2026.

A bank statement is an external record of transactions processed by a bank. The business’s bank ledger records transactions from its own accounting system. A bank reconciliation explains differences between these records and confirms the adjusted balance at a specific date.

Even when bank feeds are automated, reconciliations remain necessary because timing differences, duplicate imports, bank-only transactions, errors and fraud risks can remain.

What appears on a bank statement?

• opening and closing balance;
• deposits, transfers and card settlements;
• payments, direct debits and standing orders;
• fees, interest and foreign-exchange entries;
• dates, descriptions and reference numbers;
• reversals, returned payments and corrections.

From the bank’s perspective, a positive customer deposit may be described as a credit because the bank owes the funds to the customer. This terminology can differ from the business’s own cash-account debit balance.

Why balances differ

Differences fall into two groups:

1. Items requiring an accounting entry, such as bank charges, direct debits, receipts, errors or returned payments not yet recorded in the books.
2. Timing differences, such as deposits in transit or payments recorded by the business that the bank has not processed by the reporting date.

How to treat common items

Item	Action in accounting records	Reconciliation treatment
Bank charge or direct debit not recorded	Record the expense/liability and credit bank.	Update books before final reconciliation.
Interest or electronic receipt not recorded	Debit bank and credit the relevant income/receivable.	Update books before final reconciliation.
Deposit recorded in books but not yet by bank	No correction if valid and in transit.	Add to bank-statement side or explain as deposit in transit.
Payment recorded in books but not yet cleared	No correction if valid.	Deduct outstanding payment from bank-statement side.
Error in company books	Correct the ledger entry.	Do not leave as a permanent reconciling item.
Bank error	Notify the bank; retain evidence.	Show temporarily until corrected.

Bank reconciliation procedure

1. Obtain the bank statement and bank-ledger detail for the same account, currency and date.
2. Confirm the opening balance agrees with the prior completed reconciliation.
3. Match receipts and payments using date, amount and reference.
4. Identify bank-only transactions and update the accounting records.
5. Correct errors in the company’s books.
6. List valid deposits in transit and outstanding payments.
7. Recalculate the adjusted bank-ledger balance and reconciliation.
8. Investigate old or unusual items and obtain independent review.

Worked example

The bank ledger shows 12,450 CU. The bank statement shows 14,080 CU. The statement includes a bank fee of 80 CU and customer receipt of 1,200 CU not recorded in the books. A deposit of 900 CU is in transit and an outstanding payment is 1,410 CU.

First update the ledger:

• 12,450 − 80 + 1,200 = 13,570 CU adjusted ledger

Then reconcile the statement:

• 14,080 + 900 − 1,410 = 13,570 CU adjusted bank balance

The two adjusted balances agree.

Bank feeds and automation

A bank feed imports bank transactions, but it does not decide the correct accounting treatment in every case. Matching rules can post duplicates, apply the wrong account or hide unmatched items. Reconciliation should confirm that imported data are complete and that every transaction has appropriate evidence and classification.

ACCA’s computerised-accounting guidance confirms that bank reconciliations remain relevant because banking and accounting systems may not be fully integrated.

Internal controls

• separate payment preparation, approval and reconciliation;
• restrict online-banking access and use multi-factor authentication;
• approve new beneficiaries and changes independently;
• reconcile every material bank account regularly;
• review old outstanding payments and deposits;
• confirm that reconciliations are signed and dated;
• investigate transfers between accounts on both sides;
• protect statements and reconciliation evidence.

ACCA’s internal-controls guidance identifies reconciliations as an accounting control supporting complete and accurate records.

Common errors

• adjusting the ledger for a valid timing difference;
• leaving bank charges unrecorded;
• carrying forward stale outstanding items indefinitely;
• reconciling to the wrong date or currency;
• matching a net deposit to several gross receipts without evidence;
• treating a bank error as a permanent difference;
• reviewing only the closing balance and not the transaction flow.

Fraud warning signs

Unusual transfers, repeated round amounts, payments to new beneficiaries, altered references, dormant-account activity and reconciling items controlled by the same employee deserve investigation. A reconciliation can detect symptoms but should be combined with authorisation, access controls and transaction review.

Supporting records

Link the reconciliation to payment approvals, invoices, receipts, transfer confirmations, deposit evidence and journal entries. ACCA’s error-correction article includes a bank-reconciliation item that must be posted to the correct expense instead of remaining in suspense.

Month-end close checklist

1. Confirm all bank accounts and currencies are included.
2. Complete reconciliations to the same reporting date.
3. Post bank-only receipts, charges, interest and returned payments.
4. Investigate stale outstanding items and duplicate imports.
5. Match transfers between accounts on both sides.
6. Review unusual beneficiaries, weekend transactions and round amounts.
7. Attach supporting evidence and obtain independent approval.
8. Lock the period only after unresolved differences are documented.

For high-volume accounts, use automated matching to reduce routine work but retain human review of exceptions. The reviewer should be able to trace every adjustment from the reconciliation to the journal and source evidence.

Key takeaway

A bank reconciliation converts two different transaction records into one verified adjusted balance. Update the books for missing or erroneous entries, retain genuine timing differences temporarily and investigate every old or unexplained item.
