My ITR refund failed because the bank account was not validated. What now?

You filed your return. The tax department processed it. Your refund was due. Then a message arrives: the refund could not be credited, or the bank account is "not validated".

Nothing is lost. The money is still owed to you, but it will not move until the bank detail is fixed.

Your situation in one paragraph

A refund is not a favour. If the tax paid for a year is more than the tax you actually owe, the law says you are entitled to the excess. A failed credit is a payment problem, not a decision against you. The usual causes are a wrong account number or IFSC, a closed or dormant account, an account in someone else's name, or an account that the department's system has not accepted as validated. The fix is almost always on your side: give the department a working account that belongs to you.

What the law says about your right to the refund

Two Acts matter, because the year of the return decides which one applies.

• Returns for assessment year 2026-27 (financial year 2025-26) sit under the Income-tax Act, 1961, as amended by the Finance Act 2026.
• The Income-tax Act, 2025 applies from 1 April 2026, so it governs tax year 2026-27 onwards.

Right to refund. Section 237 of the Income-tax Act, 1961 says that if a person shows that the tax paid by him, or on his behalf, or treated as paid, for an assessment year is more than the tax he is properly chargeable with, "he shall be entitled to a refund of the excess". The Income-tax Act, 2025 keeps the same rule in section 431, for a tax year. The government's own section-by-section mapping table pairs section 237 of the 1961 Act with section 431 of the 2025 Act, under the same heading "Refunds".

The 1961 Act text opened for this article is the original wording of section 237, not the version amended up to the Finance Act 2026. Have the amended wording checked before you quote it in a legal letter.

How you claim. Section 433 of the Income-tax Act, 2025 (tax year 2026-27 onwards) says every claim for refund under that chapter is made by furnishing a return as per section 263. In plain words, the return is the refund claim. For an assessment year 2026-27 return, the 1961 Act governs; its section 239 is the counterpart, but its amended text was not opened for this article. You do not need a separate application for an ordinary excess-TDS refund. The mapping table pairs section 239 of the 1961 Act (form of claim for refund and limitation) with section 433 of the 2025 Act.

Who can claim it. For tax year 2026-27 onwards, section 432(2) of the Income-tax Act, 2025 says that where a person cannot claim or receive a refund "on account of death, incapacity, insolvency, liquidation or other cause", the legal representative, trustee, guardian or receiver can claim or receive it for that person or the estate. If the account holder has died or cannot operate the account, this is the route.

What the return form says about your bank account

The Income Tax Return forms notified for assessment year 2026-27 (the notification covering ITR-1 and ITR-4, Notification No. 45/2026) have a part called "Other Information" asking for details of all bank accounts held in India. The instructions printed under it say:

• All bank accounts held at any time during the previous year are to be reported, except dormant accounts.
• At least one account should be selected for refund credit.
• If more than one account is selected, "refund will be credited to one of the validated accounts decided by CPC after processing the return".

Three practical points follow.

One. "Validated" is the word the form itself uses. A refund goes only to an account the department's system has accepted. If none of the accounts you listed is validated, there is nowhere for the money to go.

Two. If you tick several accounts, you do not choose which one gets the money. The processing centre picks one of the validated ones. If you want the refund in a particular account, select that one and keep it in good standing.

Three. Dormant accounts are excluded from the reporting list, so do not pick one for a refund.

Why the refund bounces: common causes

Find out which of these applies to you before you touch the portal.

• Wrong account number or IFSC. One wrong digit is enough.
• Account not validated. The account was entered in the return, but the department's system has not accepted it as a validated account.
• Name mismatch. The name on the bank account differs from the name on your PAN. This is a common practical cause, not something the form text above states.
• Closed, dormant or frozen account. The bank returns the credit.
• Bank merger or IFSC change. If your bank merged with another, the old IFSC code may no longer work. Ask your bank for the current code.

The deadline clock, and what it does to your interest

There is no single date by which a failed refund must be fixed. But there is a cost to delay, and it is worth understanding.

When a refund is due, the Income-tax Act, 2025 gives you simple interest on it. Section 437(1) provides interest "calculated at the rate of 0.5% for every month or part of a month". For refunds out of tax collected at source, advance tax, or tax treated as paid under section 390(5), the period runs from 1 April of the year after the tax year to the date the refund is granted, where the return was filed by the due date in section 263(1). If the return was filed late, the period runs from the date of furnishing the return. The mapping table pairs section 244A of the 1961 Act (interest on refunds) with section 437 of the 2025 Act.

Two cautions.

First, those rates and dates are the 2025 Act's. For an assessment year 2026-27 return under the 1961 Act, the interest rule is section 244A. I did not open the amended text of section 244A for this article, so check the figure that applies to your year before you rely on a rupee number.

Second, section 437(7) of the Income-tax Act, 2025 says that if the proceedings resulting in the refund are delayed for reasons attributable to the assessee, the period of that delay is excluded from the period for which interest is payable. In plain words, if your refund sits unpaid for months because you did not fix your bank account, the department can argue that interest does not run for that stretch. Section 437(8) says that where a question arises about the period to be excluded, it is decided by the Principal Chief Commissioner, Chief Commissioner, Principal Commissioner or Commissioner, and that decision is final. So the safest course is to correct the bank detail quickly and keep a dated record that you did.

There is also a small-refund rule. Section 437(2) says no interest is payable under the main table (serial numbers 1 or 2) if the refund is less than 10% of the tax determined on processing the return or on regular assessment. If your refund is small compared with the tax computed, interest may not be payable at all.

Step by step: how to get the refund re-credited

I describe these in plain words. The portal's menu names and screens change, and I have not seen the current help pages for this process on disk, so I do not name specific menus or buttons. Use the portal's own help pages for the exact clicks.

Step 1. Read the message. Note the assessment year, the amount, and the reason given. If the message says the credit failed, it will usually say why: an invalid account, a name mismatch, or a closed account.

Step 2. Check your own bank account. Confirm the account is open, in your own name, operational (not dormant), and that the number and IFSC match your passbook or cheque leaf. If your bank merged, get the current IFSC from the bank.

Step 3. Check the name. It should match the name on your PAN. If not, ask the bank to correct it, or choose another account.

Step 4. Add or correct the bank account on the e-filing portal and get it validated. Use the profile or bank-account section of your portal account. Add the correct account, mark it for refund, and complete the validation the portal asks for. The portal tells you what it needs for validation; follow its instructions.

Step 5. Ask for the refund to be issued again. Once the right account is validated, raise a request on the portal for the refund to be reissued. The portal's service request or grievance route is the place for this. Mention the assessment year, the amount, and the new validated account, and keep the acknowledgement number.

Step 6. Follow up with proof. If nothing moves after a reasonable wait, escalate through the portal's grievance route with your acknowledgement number, bank proof and the original message attached.

Step 7. If it is adjusted, not failed. Sometimes there is no bank problem at all. The refund is held back because the department set it off against an old demand. Section 438(1) of the Income-tax Act, 2025 allows the department to set off a refund against any sum remaining payable by the same person, and section 438(2) says it must give you written intimation of the proposed action first. If you see a set-off, the answer is on the demand side, not the bank side. Check your outstanding demands and respond to the intimation.

What not to do

• Do not file a new return just to change the bank account. The return is the claim for refund, and a second return is not a bank-detail form. If the return itself has a mistake, that is a separate question about revising it.
• Do not list an account you do not own or cannot access. The refund will go there or bounce there.
• Do not select several accounts and expect to choose. The form says the processing centre decides among the validated ones.
• Do not give your bank details to anyone who calls or messages saying they will "release" your refund. Correct bank details only through your own portal login.

What to do now

• Next step: Check the message, confirm the account details with your bank, add or correct the account on the portal until it shows as validated, then request a reissue and keep the acknowledgement. (Basis: the "validated accounts" instruction in the AY 2026-27 ITR-1/ITR-4 notification, Notification No. 45/2026.)
• Deadline: There is no fixed date for a bank correction in the text I opened, so do it now. Delay attributable to you can be left out of the interest period. (Section 437(7), Income-tax Act, 2025; for an AY 2026-27 return, check the corresponding amended wording of section 244A, Income-tax Act, 1961.)
• Consequence of not acting: The refund stays unpaid, and interest for the delay period may be excluded. (Section 437(7) and (8), Income-tax Act, 2025.) Your entitlement itself continues. (Section 237, Income-tax Act, 1961; section 431, Income-tax Act, 2025.)

Have a CA review your facts before you act or file.

Frequently asked questions

Is my refund cancelled if the credit failed?
No. Section 237 of the Income-tax Act, 1961 (section 431 of the Income-tax Act, 2025) says you are entitled to the refund of the excess tax. A failed credit means the money could not be delivered, not that you lost it.

Do I have to file a fresh return to correct the bank account?
Not for the bank account alone. The return is the claim for refund (section 433, Income-tax Act, 2025, for tax year 2026-27 onwards; section 239 of the 1961 Act for assessment year 2026-27), but the bank detail is corrected through your portal profile and a reissue request. Filing another return is a separate step for correcting the return itself.

Which of my accounts will the refund go to?
The ITR-1/ITR-4 instruction for assessment year 2026-27 says that if several accounts are selected, the refund is credited to one of the validated accounts decided by CPC after processing the return. To be sure, select only the account you want.

Will I still get interest on the refund?
Possibly. For tax year 2026-27 onwards the Income-tax Act, 2025 gives simple interest at 0.5% for every month or part of a month under section 437(1), subject to the small-refund rule in section 437(2) and to the exclusion of delay attributable to you in section 437(7). For a 1961-Act year, the provision is section 244A; check its amended wording for your year before relying on a figure.

My refund was adjusted against an old demand. Is that allowed?
The department may set off a refund against a sum payable by you, but it must give you written intimation first. See section 438(1) and (2) of the Income-tax Act, 2025. Respond to the intimation and check whether the demand is correct.

The account holder has passed away. Who claims the refund?
Under section 432(2) of the Income-tax Act, 2025 (tax year 2026-27 onwards), the legal representative, trustee, guardian or receiver can claim or receive the refund for the person or the estate.
