A tax payment is complete only when the correct credit reaches the correct return. A successful bank debit does not by itself prove that the payment was made for the right PAN, payment type, or year.
This guide is for taxpayers and finance teams preparing a return during the transition to the Income-tax Act, 2025. The new Act applies from 1 April 2026 and introduces Tax Year terminology. Use the labels and instructions currently displayed on the official portal for the filing or payment you are completing, then retain evidence of what you selected.
Calculate the balance before opening the payment screen
Start with the completed return computation. Reconcile income, deductions, tax liability, interest, advance tax, TDS, TCS, and any other available credit. The amount left after that reconciliation is the figure to review for payment.
Do not estimate the balance from a headline tax rate or pay an arbitrary round figure. If the underlying computation changes, the payment requirement may change too.
| Check | Evidence to retain |
|---|---|
| Amount due | Dated computation showing liability and credits |
| Taxpayer identity | PAN and name shown in the portal session |
| Payment selection | Screenshot or note of the year and payment type selected |
| Successful payment | Challan receipt and bank debit confirmation |
| Return matching | Tax-paid schedule showing the same identification details and amount |
Confirm the year shown by the portal
Year selection deserves a deliberate check during the law transition. An AY 2026-27 return relates to income from an earlier financial year, while compliance after 1 April 2026 may use Tax Year terminology under the new Act. Do not infer the required portal option from memory.
Before paying, write down:
- the return or obligation being settled;
- the period to which it relates;
- the exact year label displayed by the portal;
- the payment type selected;
- the reason that selection matches the computation.
This short note is useful if the credit later appears under an unexpected period.
Reconcile the receipt to the return
After payment, compare the receipt with the tax-paid schedule before submitting the return. Check the challan identification details, date, amount, PAN, and payment classification. The amount entered in the return should be traceable to the receipt and the bank transaction.
Do not type identification numbers from memory. Use the downloaded receipt, and recheck each digit after entry.
Example: payment succeeded but credit does not match
Assume a taxpayer calculates a balance of ₹18,400 and the bank confirms the debit. The return does not recognise the credit because the receipt shows a different period from the one expected in the return.
The next step is not to enter the debit amount as though the mismatch does not exist. Preserve the receipt and bank proof, check the official payment guidance, and use the appropriate correction or grievance route if required. Filing with an unsupported credit can leave the return showing unpaid tax and may result in a demand.
The example illustrates a reconciliation issue. The correct resolution depends on the actual receipt, portal status, and department procedure available at that time.
Records to keep together
- final computation used to determine the payment;
- challan receipt downloaded from the official portal;
- bank debit confirmation or statement entry;
- tax-paid schedule from the filed return;
- acknowledgement and e-verification proof;
- correspondence or grievance records if a correction was needed.
Keeping the complete set matters when the portal status and bank record do not initially agree.

Resolve these issues before filing
Pause when the bank debit has no corresponding receipt, the receipt carries an unexpected PAN or year, the amount differs from the computation, or the credit is missing from the return workflow. A document-based professional review may also be useful when earlier payments, notices, or tax-credit mismatches affect the balance.
Paying again without first diagnosing the original transaction can create a second reconciliation problem. Preserve the evidence and follow the current official correction process.
Final submission check
Recalculate the return after entering the payment. Confirm that the balance payable, interest, and tax-paid schedule are consistent. After filing, save the acknowledgement and e-verification proof beside the computation and receipt.
