Income Tax · ReturnsITR verification and defective returns: deadlines and remedies
An income tax return is not complete until it is verified. Missing the 30-day window can turn an on-time return into a belated one, with a fee. Here is how verification works, how to recover from delay, and how to deal with a defective-return notice.
Filing an income tax return is a two-step process: uploading the return and verifying it. Verification confirms that you – not someone else – filed the return. An unverified return is treated as never filed.
The 30-day rule
Under the CBDT notification in force since August 2022, a return must be verified within 30 days of upload. If verified later, the date of verification is treated as the date of filing.
| Upload date | Verified on | Treated as filed on | Status |
|---|---|---|---|
| 25 July 2026 | 2 August 2026 | 25 July 2026 | On time |
| 25 July 2026 | 30 August 2026 | 30 August 2026 | Belated (after 31 July) |
| 20 December 2026 | 10 January 2027 | 10 January 2027 | Belated window over – needs condonation |
Ways to verify
- Aadhaar OTP – mobile linked to Aadhaar.
- EVC through bank account – pre-validated bank account.
- EVC through demat account.
- Net banking login to the e-filing portal.
- Digital Signature Certificate (DSC) – mandatory for audit cases and companies.
- Physical ITR-V – signed and posted to CPC Bengaluru by speed post within 30 days.
E-verification is instant and avoids postal delays.
Consequences of late verification
- Late fee under Section 234F (₹5,000, or ₹1,000 where income does not exceed ₹5 lakh).
- Interest under Section 234A for the delayed period.
- Loss of carry-forward of business and capital losses.
- Loss of the choice of old regime for business taxpayers who had to opt out by the due date.
Condonation of delay in verification
If you missed the 30-day window for a genuine reason (illness, technical failure, travel), submit a condonation request on the e-filing portal (Services → Condonation request → Delay in submission of ITR-V). State reasons with evidence. If allowed, the return is processed as filed on the original date.
Defective returns – Section 139(9)
The CPC may treat a return as defective if, for example:
- Tax audit report is required but not uploaded;
- Balance sheet and P&L are not filled where books are maintained;
- Tax payable is shown but not paid;
- The wrong ITR form is used;
- Gross receipts in Form 26AS exceed those reported and no explanation is given.
A notice gives 15 days to rectify. Respond on the portal under e-Proceedings by either filing a corrected return or explaining why the return is not defective. If you do not respond, the return is treated as invalid – as if never filed.
Worked example
Example: Pankaj, a trader in Alipur with turnover of ₹1.6 crore and profit at 5%, files ITR-3 on 20 November 2026 (within the extended date for audit cases) but forgets to ensure the tax audit report is filed. In January 2027 he receives a Section 139(9) notice.
| Step | Action |
|---|---|
| 1 | Get the tax audit done; CA uploads Form 3CB-3CD; Pankaj approves it on the portal |
| 2 | File corrected return within 15 days in response to the notice |
| 3 | Penalty exposure for late audit report remains (0.5% of turnover up to ₹1.5 lakh, subject to reasonable cause) |
Responding saves the return; ignoring it would make the return invalid, leading to best judgment assessment.
Checklist after filing
- Verify on the same day using Aadhaar OTP.
- Check the "Filed returns" status: "Successfully e-verified".
- Watch email/SMS for intimation under Section 143(1) and any defect notices.
- Keep the acknowledgement and computation.
Key takeaway
Upload is half the job – verify within 30 days, preferably immediately. If you miss it, apply for condonation; if you receive a defect notice, cure it within 15 days. Our ITR filing service includes verification and follow-up of CPC communications.

Frequently asked questions
What is the time limit to verify an ITR?
30 days from the date of uploading the return. The date of verification is treated as the date of filing if it is later than 30 days.
What happens if I verify after 30 days?
The return is treated as filed on the date of verification. If that date is after the due date, it becomes a belated return with late fee and loss of certain benefits.
Can I seek condonation for late verification?
Yes. You can submit a condonation request on the e-filing portal giving reasons; the department may allow it in genuine cases.
How long do I have to respond to a defective-return notice?
15 days from the date of the notice under Section 139(9) (Section 263(7) of the 2025 Act), extendable on request. If not cured, the return is treated as invalid.
Can I verify a return after the belated return deadline?
Verification after 30 days makes the verification date the filing date. If that falls after the belated return deadline, a condonation request is needed; otherwise the return is invalid.
Does a defective return notice mean penalty?
No. It is a request to correct the defect within 15 days. Penalty exposure arises only from the underlying default (for example, late audit).
Can I verify using my bank account if it is not pre-validated?
No. Pre-validate the bank account on the e-filing portal first, then generate an EVC.
