Monthly Bank Reconciliation Prevents 234B/234C Interest and ITR Errors
Monthly bank reconciliation catches unreconciled credits, TDS credits and bank charges before they distort advance-tax calculations or GSTR-3B. Small businesses avoid sections 234B and 234C interest and reduce correction fees when the CA prepares the ITR.
Small businesses often discover tax or GST discrepancies only when the CA prepares the ITR or GSTR-3B. By then, interest under sections 234B and 234C may already apply and extra fees are charged for corrections. Reconciling the bank statement every month catches these differences while the details are still fresh.
Why monthly reconciliation matters for tax and compliance
Unreconciled bank entries create incorrect profit figures that feed directly into advance-tax calculations. A ₹1,20,000 unreconciled credit in March can push total income into the next slab under the new regime and trigger a 234C interest charge. Monthly checks also ensure that TDS deducted by clients appears in Form 26AS before the 31 July ITR due date.
Collect the right documents before you start
Download the bank statement for the full month in PDF or Excel format. Keep the previous month’s reconciliation report, all invoices raised, purchase bills received, and the cash book or ledger printout. For businesses using presumptive taxation under section 44AD or 44ADA, also keep the summary of digital receipts to confirm the 6 % rate applies.
Match every transaction line by line
Open the bank statement and the books side by side. Tick off each credit and debit that appears in both places with the same date and amount. Note the reference number from the bank against the voucher number in the books. Stop at the first unmatched item and investigate before moving on; carrying forward errors multiplies work later.
Record journal entries for differences that belong in the books
When a bank charge of ₹850 appears on the statement but is not yet booked, pass the following entry:
| Account | Debit (₹) | Credit (₹) |
|---|---|---|
| Bank charges | 850 | |
| Bank account | 850 |
If a client deducts TDS of ₹4,500 on a ₹45,000 invoice and the net amount is credited, record:
| Account | Debit (₹) | Credit (₹) |
|---|---|---|
| Bank account | 40,500 | |
| TDS receivable | 4,500 | |
| Sales / Service income | 45,000 |
These entries keep the general ledger aligned with the bank balance that will appear in the balance sheet.
Treat bank credits and debits that do not belong to the business
A personal transfer of ₹25,000 credited by the proprietor must be moved to the proprietor’s capital or drawings account, not left as business income. Conversely, an auto-debit of ₹3,200 for the proprietor’s personal insurance premium is recorded as drawings. Leaving such items distorts taxable income and creates confusion during assessment.
Check the reconciliation statement totals against the books
After matching, the closing bank balance in the books should equal the statement balance plus outstanding cheques minus uncleared credits. Any remaining difference must be explained in writing on the reconciliation sheet. This signed document becomes the audit trail the CA can attach to the tax audit report if turnover crosses ₹1 crore.

Frequently asked questions
How often should a proprietorship reconcile if it files under the new tax regime?
Reconcile at the end of every month regardless of the regime chosen. The new regime slabs still require accurate total income figures to apply the ₹12 lakh rebate under section 87A correctly.
What happens if an entry is missed and discovered only at ITR filing time?
The CA must pass a prior-period adjustment, which may change advance-tax instalments already paid and attract interest under sections 234B and 234C. Monthly reconciliation avoids this.
Can reconciliation help with GST input tax credit claims?
Yes. When supplier payments are matched to the bank statement, the business can confirm that the invoice appears in GSTR-2B before claiming credit in GSTR-3B.
Is a handwritten reconciliation acceptable for a tax audit?
No. The reconciliation must be generated from the accounting software and exported with the trial balance and ledger so the auditor can verify it against the bank statement without manual alterations.
