You may have successfully filed your Income Tax Return, received an acknowledgement and assumed everything was complete. Then an email arrives saying your return has been treated as defective under Section 139(9).
It sounds serious, but a defective return does not necessarily mean that you have committed tax evasion or filed a fraudulent return.
Usually, it means the department has identified incomplete, inconsistent or incorrect information that needs to be corrected.
The important thing is to respond within the specified period.
What Is a Defective ITR?
A return may be treated as defective when it contains incomplete or inconsistent information in the return or its schedules, or for another reason specified under the law.
The Income Tax Department specifically states that taxpayers receive a Section 139(9) notice where their return is found defective.
The notice normally explains the defect that needs to be corrected.
Common Reasons for a 139(9) Notice
One common issue is claiming TDS credit without reporting the corresponding income.
For example, if Form 26AS shows professional receipts of ₹10 lakh on which TDS was deducted but the ITR reports only ₹7 lakh of corresponding receipts, the return may require clarification or correction.
Other common reasons include mismatches in gross receipts, incorrect PAN details or failure to provide required financial information for taxpayers reporting business or professional income.
The Income Tax Department lists several such examples in its official guidance.
How Much Time Do You Get?
The Income Tax Department's current guidance states that a taxpayer generally gets 15 days from receipt of the notice, or the period specified in the notice, to rectify the defect. An extension or adjournment may be requested where permitted.
Do not wait until the last day.
Some corrections require gathering information from banks, employers, clients or other sources.
How to Respond to a 139(9) Notice ?
Log in to the Income Tax e-Filing portal.
Go to the relevant pending action/e-Proceedings section.
Open the defective return notice and read the reason carefully.
If the defect can be corrected in the return, update the required information and submit the corrected response through the prescribed process.
The Income Tax Department confirms that taxpayers can correct defects online through the ITR response facility.
What If You Disagree With the Defect?
A taxpayer may not always agree that the return is defective.
In such a situation, the response should explain why the return is actually correct and why the identified defect does not apply.
Supporting evidence should be attached where appropriate.
Do not simply select “disagree” without explaining the facts.
What Happens If You Ignore the Notice?
Failure to respond within the stipulated period can result in the return being treated as invalid.
The Income Tax Department warns that this can have consequences such as loss of certain benefits, interest, penalty implications or loss of carry-forward of losses, depending on the circumstances.
That is why a 139(9) notice should never be ignored.
Can You File a Revised Return Instead?
This depends on whether the applicable time for filing a fresh or revised return is still available.
The Income Tax Department states that where the filing period has not lapsed, a taxpayer may be able to file a fresh/revised return or respond to the defective notice. Once the relevant filing period has lapsed, responding to the defective notice becomes important because a fresh/revised return may no longer be available.
What About AY 2026–27?
This is particularly important in 2026.
The Income-tax Act, 2025 came into force from 1 April 2026, but the department has clarified that proceedings for AY 2026–27 and earlier remain governed by the Income-tax Act, 1961.
Therefore, a defective return notice under Section 139(9) for AY 2026–27 remains a valid old-law proceeding.
For tax years governed by the new Act, the corresponding defective-return provision has been renumbered.
