Revised and Belated ITR 2026

Reviewed on 2026-06-20 by Dr. Shrawan Kumar Pathak.

Filing late or fixing an error does not mean you are stuck. The income tax law gives you three separate doors, and which one you use depends entirely on your situation. This guide is built as a set of simple if-then choices so you reach the right door in under a minute.

First, fix the year in your head. The return you file in 2026 is for the money you earned in the financial year 2025 to 2026. The tax department calls this assessment year (AY) 2026-27. Every deadline below is tied to that assessment year, so the same logic works for any year you read this in.

If you never filed your return by the original due date (around 31 July 2026 for most salaried people), then you file a belated return under section 139(4).

A belated return carries a late fee under section 234F. The fee is up to Rs 5,000. If your total income is up to Rs 5 lakh, the fee is capped at Rs 1,000. On top of that, you pay interest under section 234A at 1 per cent per month, or part of a month, on any unpaid tax counted from the original due date until you file.

If you have a business loss or a capital loss you wanted to carry forward to next year, then filing late costs you that right. A belated return cannot carry forward those losses. A house property loss is the main exception that still survives. So if carry-forward matters to you, filing on time is worth far more than the fee you save by delaying.

You can still file a belated return only until 31 December of the assessment year, or until your assessment is completed, whichever comes first. For AY 2026-27 that hard stop is 31 December 2026. Miss it, and the belated door shuts. Our step by step guide to filing ITR online walks through the actual form.

If you have already filed (on time or belated) and then notice a wrong figure, a missed deduction or a forgotten bank interest entry, then you file a revised return under section 139(5). There is no separate fee just for revising.

A revised return completely replaces your earlier one. The department then treats the latest version as your real return. You can revise more than once if you find further errors, as there is no fixed cap on the number of revisions. Before you revise, it helps to cross check your income against your Form 26AS and AIS so you correct everything in one go rather than revising again and again.

The revised return must also reach the portal by 31 December of the assessment year, or before your assessment is completed, whichever is earlier. Once the department completes the assessment of your return, the revision door is closed for that year.

Figure: step-by-step flow. If a step stalls, use the grievance or RTI route shown.

If 31 December of the assessment year has passed and you can no longer file belated or revised, then your last legal route is an updated return under section 139(8A), filed on Form ITR-U.

The Finance Act 2025 extended the ITR-U window from 24 months to 48 months from the end of the relevant assessment year, with effect from 1 April 2025. So for AY 2025-26 you have until 31 March 2030 to file an updated return.

You pay extra tax on top of the normal tax and interest, and the rate climbs the longer you wait, counted from the end of the assessment year:

• Within 12 months: 25 per cent of the tax plus interest
• After 12 and up to 24 months: 50 per cent
• After 24 and up to 36 months: 60 per cent
• After 36 and up to 48 months: 70 per cent

This is the important part. If your correction would create or increase a refund, reduce your reported tax, or report a loss, then ITR-U is not allowed. An updated return only works when you have additional income to declare and additional tax to pay. It is a voluntary honesty tool, not a way to claw back money. If you genuinely have a refund to claim and the normal windows are gone, you would instead need to approach the department, and our guide on the income tax notice and reply process explains how the department communicates in such cases.

Whichever return you file, it is not valid until you verify it. If you do not e-verify within 30 days of filing, then the department treats your return as never filed, and your late fee and effort are wasted. Verify it the same day using any of the six ways to e-verify your ITR.

If your return stays unprocessed for long, your refund is wrong, or a correction is not reflected, then do not keep refiling blindly. First check whether you actually need a rectification under section 154 rather than a revised return, because a rectification fixes an obvious error in an already processed return. If the issue is a portal or processing failure, raise a complaint through the e-Nivaran grievance module on incometax.gov.in. If that does not resolve it within a reasonable time, escalate to CPGRAMS at pgportal.gov.in. You can also track money owed to you on the ITR refund status check page.

Yes. A belated return filed under section 139(4) can still be revised under section 139(5), as long as you do it before 31 December of the assessment year or before your assessment is completed, whichever is earlier.

The fee under section 234F is up to Rs 5,000. If your total income is up to Rs 5 lakh, it is capped at Rs 1,000. You also pay 1 per cent per month interest under section 234A on any unpaid tax. Verify the current figure on incometax.gov.in.

No. Revising itself carries no separate fee. But if your original was belated, the section 234F late fee from that belated filing still stands, and any extra tax now due will attract interest.

There is no fixed cap on the number of revisions under section 139(5). You can revise again if you find further errors, provided the December deadline has not passed and the assessment is not yet complete.

No. An updated return under section 139(8A) cannot be used to claim or increase a refund, to reduce your tax, or to report a loss. It is only for declaring additional income and paying additional tax.

You can no longer file a belated or revised return for that year. Your only remaining option is an updated return (ITR-U), available for up to 48 months from the end of the assessment year, with extra tax of 25 to 70 per cent depending on how late you are.

Yes. Any return is invalid until verified. e-Verify within 30 days of filing, otherwise the department treats the return as not filed at all.
