ITR-U Updated Return: Who Can File and How Much Extra You Pay

An updated return, filed in Form ITR-U, lets you declare income you missed after the belated and revised return dates have passed. You get 48 months from the end of the assessment year. The price is additional tax of 25%, 50%, 60% or 70% of the tax and interest due, depending on how late you are.

What is an updated return, and why does it exist?

Say you find income that never reached your return: interest from an old deposit, a freelance payment, sales from a marketplace account you had forgotten. The normal windows have closed. Without ITR-U, you could only wait for a notice and face a penalty.

The updated return gives you a way to come forward on your own. The government collects the tax with a surcharge for the delay, and you close the matter before the department opens it. That trade is the whole idea: it is a paid route for adding income, not a second chance to claim benefits.

Who can file ITR-U?

The e-filing portal's guidance says the updated return is available whether or not you furnished an original, belated or revised return. The form notified for it lists the reasons you may pick:

• Return not filed earlier.
• Income not reported correctly, or reported under the wrong head.
• Wrong rate of tax.
• Reduction of a loss, a carried forward loss, unabsorbed depreciation or a tax credit.
• Return in response to a notice under section 148.

Who cannot file it?

Does your update add tax? If not, stop here. The portal states that an updated return cannot result in a bigger loss, a lower total tax liability or a bigger refund. In plain terms:

• No refunds. If you forgot to claim TDS or a deduction and want money back, ITR-U is not the route.
• No loss returns. You cannot use it to report a loss or to increase one. The current form does let you reduce a loss you claimed earlier.
• No second attempt. One updated return per year.
• Not after the department has moved. Tax publishers list these bars from the provisos to section 139(8A): a search, a survey or a requisition of books in your case, or an assessment or reassessment that is pending or completed for that year. Read the form's instructions or ask a professional if any of these touch you.

One door has opened this year. The ITR-U form notified on 30 March 2026 has an option for a return filed in response to a notice under section 148, which is the notice for reopening an assessment. That route carries additional tax 10 percentage points higher.

How long do you have?

The form is titled for persons updating income "within forty-eight months from the end of the relevant assessment year". The assessment year is the year after the financial year in which you earned the income. For FY 2025-26 the assessment year ends on 31 March 2027, so the window runs to 31 March 2031.

For FY 2025-26 you do not need ITR-U yet. A belated return is open until 31 December 2026, and it is far cheaper.

How much extra do you pay?

The additional tax is a percentage of the tax and interest payable on the updated return. The notified form carries these rates.

Three things to keep in mind. The percentage is on tax plus interest, not on the income. The band changes on 1 April each year, so a return filed on 31 March can cost much less than one filed a day later. And you pay the full amount before you file. The form asks for the challan details.

A worked example

Rohit is a consultant in the 30% slab. He filed his return for FY 2023-24 on time, but left out professional fees of Rs 1,50,000 from one client. He decides to correct it on 12 November 2026.

• Tax on Rs 1,50,000 at 30%: Rs 45,000. Cess at 4%: Rs 1,800. Total Rs 46,800.
• Interest for the delay: we assume Rs 15,000 for this example. The filing utility works out the exact figure.
• Tax plus interest: Rs 61,800.
• FY 2023-24 is assessment year 2024-25, which ended on 31 March 2025. November 2026 falls in the 12 to 24 month band, so additional tax is 50% of Rs 61,800, or Rs 30,900.
• Total to pay: Rs 92,700.

Had he acted before 31 March 2026, the rate would have been 25% and the additional tax about half. If he waits past 31 March 2027, it becomes 60%. The income is the same. Only the date changed.

How to file it

1. Pull out the return you filed for that year, if any, and your AIS for that year.
2. Work out the income you are adding and the reason.
3. Prepare the regular ITR form for that year again with the corrected income. ITR-U is filed along with it and has two parts: general information, and the computation of updated income and tax.
4. Pay the tax, interest and additional tax, and enter the challan details.
5. Submit and verify the return.

ITR-U, revised return or belated return?

If a cheaper route is still open, use it. ITR-U is the last one in the line.

The mistake people usually make

They find a missed refund or an unclaimed deduction from two years ago and assume ITR-U will bring it back. It will not. The second mistake is delay: people sit on an AIS mismatch for months and cross 31 March, which moves them to the next band. The third is filing ITR-U in a hurry with one more error in it. You get only one, so check it against your AIS line by line.

Should you do this yourself?

A single missed interest entry with a clear amount is manageable on your own. Take help when the missed income is from business, when several years are involved, when a notice has already arrived, or when you are unsure whether you are barred. The additional tax is not refundable if you get the working wrong.
