How to Revise your Income Tax Return in Response to the Notice?

One should understand that receiving a tax notice should not necessarily be a cause for panic or worry. Instead, you must view it as a chance to amend mistakes made in your original income tax return. Under Section 139(5) of the Income Tax (IT) Act, taxpayers are entitled to revise their IT returns. This provision allows taxpayers to rectify any unintentional errors or omissions in their IT returns, even after receiving a tax notice u/s 139 (9) of the Income Tax Act. The revision can be made prior to the expiry of one year from the end of the relevant assessment year or before the completion of the assessment year, whichever comes earlier. This flexibility provides taxpayers with the opportunity to correct discrepancies and ensure accuracy in their tax filings.

Can I file a fresh or revised return instead of responding to 139(9)?

No. Once you receive a Section 139(9) defective return notice, you must respond to the notice on the e-Filing portal. Filing a fresh or revised return does not count as a valid response to the defect notice.

The Income Tax Department treats the response to Section 139(9) as a separate compliance. If you do not respond within the given time, the department may treat your return as invalid, even if you file a revised return later.

To fix the issue, you should agree with the defect and submit the corrected details through the “Submit Response” option under e-Proceedings on the portal.
