Belated and revised returns: fixing a missed or wrong ITR for AY 2026-27
If you missed the return deadline or filed with a mistake, there are three ways back: a belated return, a revised return, and, for later corrections, an updated return. Each has its own deadline and cost.

Quick answer
For AY 2026-27, a belated return can be filed until 31 December 2026 with a late fee of ₹5,000 (₹1,000 if income is up to ₹5 lakh). A revised return can be filed until 31 March 2027, with a fee after 31 December. After that, an updated return (ITR-U) is possible within 48 months.
- Belated returns lose business and capital loss carry-forward
- ITR-U costs 25% to 70% extra tax
- Revise as many times as needed within the window
The three options
| Belated return | Revised return | Updated return (ITR-U) | |
|---|---|---|---|
| When | You missed the due date | You filed, then found a mistake | After the belated or revised window has closed |
| Deadline for AY 2026-27 | 31 December 2026 | 31 March 2027 | Up to 48 months from the end of the assessment year |
| Late fee or cost | ₹5,000; ₹1,000 if income up to ₹5 lakh | None up to 31 December; fee of ₹1,000 or ₹5,000 after that | Additional tax of 25% to 70% of tax and interest, depending on delay |
| Can claim a refund or lower tax? | Yes | Yes | No, only increase income or tax |
| Earlier completion of assessment | Deadline ends if assessment completes first | Same | Barred in some cases, such as after a search or notice |
Return due dates for AY 2026-27 were 31 July for most individuals and 31 August for non-audit business cases; see our ITR due dates guide.
What a belated return costs you
- Late fee: ₹5,000, or ₹1,000 if total income does not exceed ₹5 lakh. No fee if income is below the basic exemption limit and you are filing only to claim a refund.
- Interest at 1% a month on unpaid tax from the due date.
- Losses: business losses and capital losses of the year cannot be carried forward; house property loss can.
- Regime: people with business income lose the ability to opt out of the new regime for the year.
- Refund interest runs from the date of filing rather than from 1 April.
When and how to revise
- Revise when you missed income, claimed a wrong deduction, picked the wrong ITR form, or entered wrong bank details. A revised return replaces the original entirely.
- You can revise more than once within the window; the last one counts.
- A belated return can also be revised.
- From 1 January 2027, revising a return for AY 2026-27 carries a fee of ₹1,000 (income up to ₹5 lakh) or ₹5,000.
- If you received an intimation that your return has a defect, respond to the defect notice instead; that is a different process.
In the ITR form, choose the filing section for revised return and quote the acknowledgement number and date of the original. The steps are otherwise the same as filing online.
Missed even 31 December?
- Updated return (ITR-U) can be filed for up to 48 months after the end of the assessment year, only to report more income or pay more tax. The additional tax is 25% within 12 months, 50% within 24 months, 60% within 36 months, and 70% within 48 months, on top of tax and interest.
- Condonation of delay: for genuine hardship, you can apply to the tax authorities to allow a late return claiming a refund or carrying forward a loss.
- If a notice has arrived, reply to it rather than filing on your own; see our guide to income tax notices.
