PAN-Aadhaar Linking Deadline: As 2025 comes close to the end, taxpayers in India need to be extra careful about one important tax deadline. If you have already filed your income tax return and made a mistake you also only have time till December 31, 2025 to fix it. After that date you will lose the chance to file a revised ITR even if the tax department has not processed your return yet.
A revised ITR under Section 139(5) helps people correct errors like wrong income details, missing deductions, or refund mistakes. This chance ends strictly on December 31, 2025. It does not matter whether your return status shows processed or unprocessed. Once the date passes, the option closes fully.

Revise Your ITR Before the Deadline
Many people pay extra tax during the year through TDS or advance tax and expect a refund later. If there is any small mistake in the return, your refund amount may reduce or stop completely. That is why its advised checking your filed return carefully and correcting errors before the deadline.
If you miss this date, fixing mistakes becomes very hard. Even if the error is small, you may lose the chance to claim a higher refund. This is why tax experts call this an urgent deadline for taxpayers.
What Happens If CPC Processes ITR Late?
The Centralised Processing Centre has time till December 31, 2026 to process ITRs filed for Assessment Year 2025-26. ET reported, quoting Chartered Accountant Suresh Surana, that returns filed on July 31, 2025, September 16, 2025, or December 31, 2025 can legally be processed till December 31, 2026.
“If CPC does not process the return within this prescribed period, it loses the legal authority to issue an intimation under Section 143(1) thereafter,” he said.
Once this time limit ends, the return becomes final as filed. No changes or adjustments can be made by CPC after that.

What to do After December 31, 2025?
If your ITR gets processed after December 31, 2025 and shows an error, you cannot file a revised return. In that case, you can only file an ITR-U or submit a rectification request. But after December 31, 2025, an ITR-U is allowed only if it does not reduce tax or increase refund.
Taxpayers can also raise complaints through the income tax grievance portal if needed.
