Defective return notice under Section 139(9) - citizen guide 2026

If the Income Tax Department flags your ITR as defective under Section 139(9), you have just 15 days from the notice date to fix it, or your entire return is treated as invalid and your refund, carried-forward losses and exemptions can vanish.

A defective return notice is an intimation from your Assessing Officer that the ITR you filed has an error or omission, such as tax paid not matching the return, a missing audit report, or an incomplete income schedule. It is not a penalty by itself, but a chance to rectify the return before it is rejected.

Defective returns are governed by Section 139(9) of the Income Tax Act, 1961, administered by the Income Tax Department. The section states the Assessing Officer “may intimate the defect to the assessee and give him an opportunity to rectify the defect within a period of fifteen days from the date of such intimation”. If the defect is not rectified in that window, “notwithstanding anything contained in any other provision of this Act, the return shall be treated as an invalid return”.

There is a relief built in. The same section allows that where the assessee rectifies the defect after the 15 days but “before the assessment is made, the Assessing Officer may condone the delay and treat the return as a valid return”. But this is discretionary, not a right. In a 2024 order, the Income Tax Appellate Tribunal at Rajkot, applying an Allahabad High Court principle, held that an order treating a return as invalid under Section 139(9) does not appear in the appealable orders listed under Section 246A, so it cannot be challenged in a normal appeal. The practical takeaway: respond on time, because the easy route to undo an invalid-return finding does not exist.

1. Log in to the e-filing portal at incometax.gov.in with your PAN or Aadhaar and password.
2. From the Dashboard, go to Pending Actions, then e-Proceedings, then Self.
3. Find the defective notice under Section 139(9) and click View Notice.
4. Open the Notice or Letter PDF to read the exact defect described and the response deadline.
5. Click Submit Response.
6. Choose Agree if you accept the defect. Select the offline response mode, pick your ITR type, and upload the corrected ITR JSON file.
7. Choose Disagree if you believe there is no defect, and write a clear reason explaining why.
8. Tick the declaration checkbox and submit. Note the Transaction ID shown on the confirmation screen.

• The Section 139(9) notice PDF downloaded from e-Proceedings.
• Your originally filed ITR acknowledgement and the ITR JSON or utility used.
• Form 26AS, the Annual Information Statement and Form 16 or 16A to fix any mismatch.
• A corrected ITR JSON generated from the offline utility or the online form, if you Agree.
• Supporting proof, like a tax audit report or balance sheet, if the defect relates to a missing schedule.

• Ignoring the 15-day clock. Once it lapses without rectification, your return is treated as invalid under Section 139(9).
• Submitting in a hurry. You cannot update or withdraw your response once it is submitted.
• Choosing Disagree without a solid reason, when the safer fix is to Agree and upload a corrected return.
• Uploading a JSON for the wrong assessment year or wrong ITR form, which creates a fresh mismatch.
• Assuming you can appeal later. An invalid-return order under Section 139(9) is not listed as appealable under Section 246A.

You get 15 days from the date of receiving the notice, or the period specified in the notice. You may seek an adjournment and request an extension, but do not assume it will be granted.

Your return may be treated as invalid. The consequences can include penalty, interest, non carry-forward of losses, and loss of specific exemptions, as the income tax FAQ warns.

No. The portal states you cannot update or withdraw your response once it is submitted. Review everything carefully before you click submit.

If you Agree, you accept the defect and upload a corrected ITR JSON. If you Disagree, you believe there is no defect and must write your reasons. Agree is usually the safer choice when the defect is genuine.

Log in, then go to Dashboard, Pending Actions, e-Proceedings, Self. Click View Notice against the Section 139(9) item, then Submit Response.

Yes. You can authorize another person, such as your chartered accountant, to respond to the defective notice under Section 139(9) on the e-filing portal.

Possibly. If you rectify it after 15 days but before the assessment is made, the Assessing Officer may condone the delay and treat the return as valid. This is discretionary, so do not rely on it.

An order treating a return as invalid under Section 139(9) is not listed among appealable orders under Section 246A. A 2024 ITAT Rajkot order, applying an Allahabad High Court principle, confirmed this, so timely response matters.
