Auditing cash and bank balances looks simple because the year-end numbers are usually easy to locate. In practice, these balances can carry risks involving existence, completeness, cut-off, ownership, restriction and presentation. A strong audit therefore goes beyond agreeing the ledger to a bank statement or physically counting cash.
What should an auditor establish?
The objective is to obtain appropriate evidence that recorded cash and bank balances exist, belong to the entity, are complete and correctly measured, and that restrictions or unusual arrangements are properly understood. ICAI's Guidance Note on Audit of Cash and Bank Balances specifically covers internal controls, cash verification, bank verification, bank reconciliation statements, confirmations, inoperative accounts, fixed deposits, remittances in transit and valuation and disclosure considerations.
1. Start with the bank-account universe
Do not begin only with accounts appearing in the trial balance. Obtain management's complete list of current accounts, savings accounts where relevant, overdrafts, cash-credit accounts, fixed deposits and other banking arrangements. Compare it with prior-year files, bank correspondence, loan documents and other records that may reveal accounts omitted from the ledger.
This completeness step matters because agreeing known balances proves little about an account that was never included in the accounting records.
2. Understand and test key controls
ICAI's guidance highlights segregation of incompatible functions, authorisation, recording, safe custody and reconciliations. In practical terms, the person who initiates or approves payments should not have unrestricted ability to alter beneficiary master data and independently reconcile the same bank account. Where segregation is limited, stronger review controls may be needed.
- Check who can create and approve payments.
- Review controls over cheque books, banking tokens and credentials.
- Understand who prepares bank reconciliations and who reviews them.
- Inspect evidence that old or unusual reconciling items are investigated.
3. Verify cash on hand
Where physical cash is material, plan an appropriate cash count and reconcile the count to the books. ICAI's guidance specifically addresses timing of verification, procedures where balances are unusually large, IOUs, discrepancies and frequency of verification.
During a count, identify denominations and other items separately rather than accepting one aggregate figure. Investigate IOUs, employee advances, undeposited receipts or non-cash items that have been included as cash. If the count occurs on a date different from the reporting date, perform a roll-back or roll-forward reconciliation using supporting transactions.
4. Obtain reliable evidence for bank balances
For bank accounts, corroborate ledger balances using appropriate external evidence. The ICAI guidance expressly includes bank confirmations within bank-balance verification. Confirmation work should be controlled by the auditor rather than delegated in a way that compromises the reliability of the response.
Do not restrict attention to positive balances. Overdrafts, liens, guarantees, fixed deposits and restrictions may affect classification, disclosure or the entity's liquidity position even when the headline cash balance is correct.
5. Audit the bank reconciliation, not just its arithmetic
A bank reconciliation can add up perfectly and still contain problematic items. Reperform the reconciliation, agree the book and bank starting points to reliable records, and inspect material reconciling items. ICAI specifically identifies examination of bank reconciliation statements and unusually old outstanding items as part of bank verification.
Pay particular attention to cheques or payments outstanding for an unusually long period, deposits in transit that do not clear shortly after year-end, unexplained reversals and entries that repeatedly roll forward. Trace significant items to subsequent bank activity and supporting documentation.
Worked illustration
Assume the ledger shows a bank balance of Rs. 18,40,000 at year-end. The reconciliation contains cheques issued but not yet presented of Rs. 3,20,000 and deposits in transit of Rs. 1,10,000. The auditor should not merely recompute the reconciliation. The Rs. 3,20,000 should be traced to payment records and subsequent presentation, while the Rs. 1,10,000 should be traced to deposit evidence and subsequent bank credit. If a large deposit remains uncleared well after year-end, investigate whether it was genuinely deposited before the reporting cut-off.
6. Test cut-off and unusual transfers
Review significant receipts and payments around year-end. Where money moves between two accounts of the same entity near the reporting date, inspect both sides of the transfer to ensure the transaction is recorded consistently and is not temporarily counted twice. Cut-off testing is especially important where balances change sharply in the final days of the period.
7. Consider fixed deposits, foreign currency and restrictions
ICAI's guidance includes fixed deposits, remittances in transit and valuation of foreign-exchange transactions among bank-verification areas. Agree deposits to supporting evidence, understand maturity and lien conditions, and assess whether the balance is truly available as unrestricted cash. For foreign-currency balances, verify the relevant closing translation and resulting accounting treatment under the applicable financial-reporting framework.
Documentation checklist
- Complete bank-account and deposit listing reconciled to the ledger.
- Cash-count documentation and explanation of differences.
- Bank confirmations or other appropriate external evidence.
- Year-end bank statements and reconciliation workings.
- Subsequent clearance evidence for material reconciling items.
- Support for fixed deposits, liens, restrictions and overdrafts.
- Cut-off testing for significant year-end receipts, payments and transfers.
- Evidence of conclusions on classification, valuation and disclosure.
Common audit mistakes
- Testing only accounts already listed by management without addressing completeness.
- Treating a mathematically correct bank reconciliation as sufficient audit evidence.
- Ignoring old outstanding cheques or deposits in transit.
- Counting IOUs or unsupported advances as physical cash.
- Overlooking liens or restrictions attached to deposits.
- Failing to test both sides of year-end inter-bank transfers.
Practical takeaway
A good cash-and-bank audit combines completeness of the account universe, physical verification where relevant, reliable external evidence, disciplined reconciliation testing, cut-off work and careful review of restrictions and presentation. The balance may be easy to calculate; the real audit work is establishing that it is complete, genuine, available as represented and properly reported.
