What is this notice?
A notice under Section 139(9) is issued when your income-tax return is treated as defective — for example, missing or inconsistent information. You must correct the defect, usually within 15 days, or the return may be treated as invalid (as if never filed).
Common reasons it is issued
- Mismatch between income declared and TDS/26AS/AIS
- Books/accounts details or required schedules not filled
- Tax payable not paid before filing; wrong ITR form used
How to reply — step by step
- Read the exact defect code and description in the notice.
- Prepare a corrected return / response addressing precisely that defect.
- Respond on the e-filing portal within 15 days (seek an extension if needed).
- Confirm the return is accepted as valid after the correction.
