Section References

|---|---|---|
| Defective Return | Sec 139(9) | Sec 263(9) |

What is This Notice?
A notice under Section 139(9) of the Income Tax Act, 1961 [Section 263(9) under the new Act] is issued when your filed Income Tax Return is considered "defective" — meaning it is incomplete in a specific technical or procedural sense as defined under the Act.
Critical Point: A defective return is not the same as a wrong return. The department is not alleging fraud or incorrect income declaration — it is telling you that your return is technically incomplete and needs to be corrected. This is a relatively lower-severity notice, but it must be addressed promptly.
Common Reasons for a Defective Return Notice
The following are the most frequently occurring defects that trigger a Section 139(9) notice:
Return-level defects
- Part B-TTI (Tax on Total Income) is incomplete or not filled
- Tax computed is inconsistent with income declared
- Tax payable is shown as zero despite TDS credits being claimed
- Discrepancy between tax computed in ITR and tax actually paid
Schedule-level defects
- Schedule AL (Assets and Liabilities) not filled despite total income exceeding ₹50 lakh
- Schedule FSI (Foreign Source Income) missing despite foreign income declared
- Schedule FA (Foreign Assets) not filled despite foreign assets held
- Schedule 80G / 80GGC not filled despite deductions claimed
- Required schedules left entirely blank
Computation defects
- Self-assessment tax paid not matching Challan details
- Advance tax payments not reconciling with quarterly breakup
- TDS credit claimed not matching Form 26AS or AIS
Filing mode defects
- Return filed using wrong ITR form for the applicable income type
- Digital signature missing where mandatory (companies, LLPs)
- Verification (ITR-V) not submitted within 30 days of e-filing (for non-digitally-signed returns)
Your Deadline
What You Must Do
Read the notice completely
Identify the exact defect(s) cited. The notice will specify the nature of the defect — read it carefully and note the defect code or description provided by the department.
Access your filed return
Log into the Income Tax e-Filing portal (incometax.gov.in) and download your original filed ITR. Review the specific field, schedule, or computation identified in the notice.
Identify and correct the defect
Based on the notice, identify the specific field, schedule, or computation issue. Prepare the corrected data — including any supporting documents (Form 26AS, AIS, Challan receipts, foreign asset details) needed to fill in the missing information.
File a fresh / revised return
You cannot simply send a letter — you must file a corrected return through the e-Filing portal. Use the "Response to Defective Notice" option under the e-Proceedings / My Account section of the portal. This ensures the corrected return is linked to the original notice and treated as a valid response.
Download and preserve the acknowledgment
After filing the response, download the acknowledgment. Keep a record of the notice DIN, the date of response, and the corrected ITR acknowledgment number. These are essential if the matter is ever questioned at a later stage.
What Happens If You Do Not Respond
If you do not respond within 15 days and no extension is granted:
- The return is treated as invalid / not filed under Section 139(9) of the 1961 Act
- Late filing fees under Section 234F become applicable (₹1,000 if total income ≤ ₹5 lakh; ₹5,000 if total income > ₹5 lakh)
- Carry-forward of losses (if any) is denied — a return must be validly filed on time to carry forward losses
- TDS refund claims may be rejected or delayed
- The Assessing Officer may treat the return as a fresh filing — affecting limitation timelines for assessment
