Defective Return – Meaning & How to Respond
Completing an annual income tax return (ITR) is mandatory; however, many taxpayers have received communication via email or SMS from the Income Tax Department indicating that their return has been labelled (flagged) as “Defective” under Section 139(9). This can lead to a great deal of confusion and anxiety. So let's take a look at what it means for a return to be labelled “defective,” the reasons for a return being flagged as defective and how to appropriately respond to a defective return in a calm and appropriate manner
What is a Defective Return?
A defective return is an income tax return that has been filed but contains missing, inconsistent, or incorrect information. Due to these defects, the Income Tax Department is unable to process the return properly.
Important point to note:👉 A defective return is not the same as a rejected return. The department gives you an opportunity to correct the mistakes.
Common Reasons Why a Return Becomes Defective
Some of the most frequent reasons are:
• Tax payable shown in return but not paid• Income shown but mandatory schedules not filled• Balance Sheet or Profit & Loss Account not attached where required• TDS claimed but not reflected properly in schedules• Incorrect selection of ITR form• Audit report not uploaded or mismatch in audit details• Gross receipts mentioned but no income computation provided• Presumptive income selected incorrectly
In most cases, defects arise due to technical or clerical errors, not intentional mistakes.
How Will You Know Your Return is Defective?
The Income Tax Department will send:
• Email on your registered email ID• SMS on registered mobile number• Notification on the Income Tax Portal
The notice clearly mentions:
• That the return is defective under Section 139(9)• Reason for defect• Time limit to respond (usually 15 days)
Time Limit to Respond
You must respond to the defective return notice within 15 days from the date of intimation.
If you do not respond within the given time:
• The return may be treated as invalid• It will be considered as not filed at all• You may lose benefits like carry forward of losses, refunds, or deductions
How to Respond to a Defective Return (Step-by-Step)
Responding to a defective return is simple if done correctly:
Step 1: Log in to Income Tax Portal
Go to the Income Tax e-filing portal and log in using your credentials.
Step 2: Go to Pending Actions
Navigate to:e-File → Pending Actions → Defective Return
Step 3: Read the Defect Carefully
Check the exact reason mentioned by the department. This will guide you on what correction is required.
Step 4: Correct the Mistake
You may need to:
• Pay pending tax and update challan details• Upload missing Balance Sheet / P&L• Correct income details• Change ITR form (if wrongly selected)• Upload audit report
Step 5: Submit the Response
After correction, submit the response online. Once accepted, the return will be treated as a valid return.
Can a Defective Return Be Revised?
Yes. In many cases, responding to a defective return is similar to filing a corrected return. However, it is different from a normal revised return.
If you are unsure, it is advisable to take professional help to avoid further complications.
Practical Tip for Taxpayers
• Do not ignore defective return notices• Always respond within time• Keep tax payment proofs ready• Cross-check income, TDS, and schedules before filing• Seek professional assistance if the defect involves audit or business income
Conclusion
A defective return is not a penalty or offence. It is simply the Income Tax Department’s way of asking you to correct missing or incorrect details. If addressed on time, there are no negative consequences.
Prompt action and correct compliance ensure that your return remains valid and your tax records stay clean.
If you have received a defective return notice and are unsure how to respond, professional guidance can save time, stress, and future notices.
