Income Tax Return Deadline: The I-T Department has allowed taxpayers to file a revised or belated income tax return for the relevant assessment year on or before December 31, 2025. Taxpayers who have made mistakes during submission can file a revised ITR on their income under Section 139 (5) of the IT Act.
Here’s what taxpayers must know
Such notices are often routine. Taxpayers and stakeholders must note that the revision window for filing a revised or belated ITR closes on Dec 31. After this date, you will not be allowed to do it.

What happens if you miss the December 31 deadline?
According to Mihir Tanna, Associate Director of Direct Tax, SK Patodia & Associate LLP CAs, people can change their income tax data through “Updated Return” or by filing ITR if the application of condonation is accepted. One cannot revise their Income Tax Returns after December 31, 2025.

The expert told Mint, “Before filing an updated return, the taxpayer needs to pay an additional tax (plus interest) on the undisclosed income. It cannot be used to claim a refund or reduce a tax liability.” In the case of a condonation of delay or an official permission by the I-TDepartment, the taxpayer can apply to the prescribed authority to avail refunds or carry forward losses.
Growing demand for ITR deadline extension date
There is a growing demand among taxpayers and CAs to extend the due date again. In a post on X, CA Himank Singla said, "Belated & Revised ITR due dates should be extended to 31st March 2026 (due to flurry of Notices & Intimations in last 7 days)."
Another Chartered Accountant, Chirag Chauhan, said that the due date for filing belated or revised ITR should be extended to January 31. "Income Tax Department has sent a record number of notices to taxpayers for: Fake deductions, fake political donations, fake trust donations, non-disclosure of foreign assets, form 16 - Salary ITR mismatch. The last date to revise returns is 31 Dec," he added.
