Income Tax Return: Can you revise your ITR after December 31? Here’s what taxpayers can do if you have a tax refund claim

People who are looking to file their ITRs for the financial year ended 2024-25 or the assessment year 2025-26 will have to file the same with the authorities on or before 31 December 2025.

The Income Tax Department has allowed taxpayers to file a revised or belated income tax return for the relevant assessment year up to December 31, 2025. This option is useful for people who made mistakes while filing their original return. Such corrections can be made under Section 139(5) of the Income Tax Act. These reminders are routine, but taxpayers should take note that December 31 is the final date. Once this deadline passes, you will no longer be allowed to file a revised or belated return for that year.

People who are looking to file their ITRs for the financial year ended 2024-25 or the assessment year 2025-26 will have to file the same with the authorities on or before 31 December 2025. You will not be able to file a revised or belated ITR after the revision window closes on 31 December 2025.

What if you miss the December 31 deadline?

According to Mihir Tanna, Associate Director (Direct Tax) at SK Patodia & Associate LLP, taxpayers still have limited options after the deadline. They may correct their tax details by filing an Updated Return or by submitting an ITR only if a condonation request is approved by the tax department. However, revising a return in the normal way will not be possible after December 31, 2025.

He explained that filing an updated return comes with a cost. The taxpayer must pay additional tax along with interest on any income that was not disclosed earlier. This option cannot be used to claim a refund or lower the tax amount already due.

In special cases, if the Income Tax Department officially allows a delay, the taxpayer can apply to the designated authority. Only then can they claim a refund or carry forward losses.

Why should you file a revised return?

ClearTax data shows that taxpayers should file a revised income tax return if they have made any of the following errors while filing their previous ITR.

• In case the taxpayer has mistakenly omitted, reduced, or exaggerated their income.
• In case the taxpayer omitted deductions or claimed excess deductions or exemptions on their initial return.
• In case of miscalculations or missed necessary disclosures in their filing.
• In case the taxpayer had chosen the wrong ITR form.
• In case the taxpayer claimed less refund than they were eligible for.

Demand for ITR deadline extension

There is increasing pressure to extend the deadline for filing belated and revised income tax returns. Many taxpayers and chartered accountants say more time is needed, especially after a surge in tax notices issued in recent days.

Chartered Accountant Himank Singla wrote on X that the due date for belated and revised ITRs should be pushed to March 31, 2026. He said a large number of notices and intimations have been sent by the tax department in the last week, making it difficult for taxpayers to respond and correct their returns in time.

Another CA, Chirag Chauhan, also called for an extension, suggesting the deadline be moved to January 31. He pointed out that the Income Tax Department has issued a record number of notices related to issues such as fake deductions, false political and trust donations, non-disclosure of foreign assets, and mismatches between Form 16 and salary details in ITRs.

With the current deadline set for December 31, many professionals believe an extension would give taxpayers a fair chance to review notices and make necessary corrections.

What you can do if you are expecting a tax refund

Tax expert Surana explains that once the legal time limit for the Centralised Processing Centre (CPC) to process an income tax return is over, the return is treated as final. After this stage, CPC cannot make any changes under Section 143(1), whether it leads to a tax demand or any other adjustment.

He says that if a refund is due as per the return already filed, the taxpayer has the right to receive that refund. Along with the refund amount, the taxpayer is also eligible for interest under Section 244A. This interest is calculated from the applicable date until the refund is actually paid.

If your return has not been processed even after the allowed time period, Surana advises taxpayers to take action instead of waiting. You can raise an online grievance through the e-Nivaran or CPGRAMS system, or file a complaint using the Income Tax Department’s e-filing portal. Another option is to submit a written request asking for the return to be processed.
