Belated ITR Filing: If you made a mistake or omitted any information while filing your Income Tax Return (ITR) for the 2025-26 assessment year (FY2024-25), be careful. Failure to file your revised ITR by December 31st could jeopardize your tax refund, especially if the information you provided and the data available with the department don’t match.

Why is this date important?

December 31, 2025, is the deadline for filing both revised and belated returns. When the Income Tax Department’s Processing Center (CPC) examines your return, it detects any errors and sends you a notification. However, if your return is examined after December 31 and an error is discovered, you won’t have a chance to correct it. According to report, once this deadline is passed, chartered accountant Suresh Surana explained, taxpayers will not be able to make corrections in your return even if the department has not processed your return by that time.

Who might face difficulties?

Abhishek Soni, CEO of Tax2win, says that many employed people are receiving such notices. This is mostly happening in cases where employees have failed to pay their salaries. While claiming exemptions like 80C, 80D or HRA at the time of filing, they did not provide these details to their office/employer when the company was deducting TDS from their salary. Manish Bawa, Partner, Nangia Global, says such mismatches are very common and often occur due to minor reporting errors or changes in tax regimes. For example, the company may have deducted TDS as per the new tax regime, but the employee may have filed their return under the old tax regime.

Did you get the message?

The Income Tax Department has issued notices to many taxpayers SMS and sent an alert via email. The department stated that the information provided in the ITR and the data available with the department did not match. Due to this mismatch, refunds for many individuals have been withheld, and they have been asked to file revised ITRs by December 31. A statement issued by the department on Tuesday stated that some taxpayers had claimed exemptions to which they were not entitled.

What to do on notice?

Abhishek Soni says that receiving a notice from the Income Tax Department means that the data they have and your return don’t match. Ignoring this could result in heavy tax, interest, or a legal notice. Manish Bawa advises that if the department points out an error, correct it immediately. This can be corrected by filing a revised return by December 31, 2025. If you don’t correct the error, the department may reject your claim, forcing you to pay higher taxes along with penalties and interest.
