The thirty-day verification window, the six permitted modes, and what happens if the return is left un-verified -- under section 139 of the Income-tax Act, 1961 read with Rule 12 of the Income-tax Rules, 1962 and Central Board of Direct Taxes Notification No. 5/2022 dated 29 July 2022
Taxpayer Brief
Filing the Income Tax Return on the e-filing portal is only the first half of the process. Until the return is verified -- either electronically by one of the five permitted electronic modes or physically by signing the printed Income Tax Return Verification Form (Form ITR-V) and posting it to the Centralized Processing Centre, Bengaluru -- the return is not treated as filed. Until 31 July 2022 the verification window was 120 days; with effect from 1 August 2022 the Central Board of Direct Taxes reduced it to 30 days. A return left un-verified beyond 30 days is treated as never filed -- with all the consequences that flow, including loss of carry-forward of losses, section 234F late fees, and potential section 271F penalty exposure on belated re-filing.
1. Statutory Foundation
The verification requirement flows from sub-section (9) of section 139 of the Income-tax Act, 1961 read with Rule 12 of the Income-tax Rules, 1962. The Central Board of Direct Taxes Notification No. 5 of 2022 dated 29 July 2022 reduced the window from one hundred and twenty days to thirty days for returns furnished from 1 August 2022 onwards. Section 140A read with the e-filing portal architecture allows six modes of verification.
2. The Six Modes of Verification
Mode | How It Works | Best Suited For |
|---|---|---|
1. Aadhaar One-Time Password | Six-digit One-Time Password sent to the mobile number linked to the Permanent Account Number-Aadhaar mapping; entered on the portal within ten minutes | Individual taxpayers with Aadhaar-Permanent Account Number linkage updated |
2. Net Banking Electronic Verification Code | Login to the bank's net-banking portal; click 'Income Tax e-filing' link; redirected to the e-filing portal pre-authenticated | Account-holders with active net-banking with one of the listed banks |
3. Bank Account Electronic Verification Code | Generate Electronic Verification Code from the bank account that has been pre-validated on the portal; ten-digit code valid for seventy-two hours | Taxpayers without net-banking but with a pre-validated bank account |
4. Demat Account Electronic Verification Code | Generate Electronic Verification Code through the pre-validated demat account; same seventy-two-hour validity | Investors with demat account linked to Permanent Account Number |
5. Digital Signature Certificate | Class II / Class III Digital Signature Certificate signed in the e-filing utility | Mandatory for tax-audit cases; companies and Limited Liability Partnerships always; otherwise optional |
6. Income Tax Return Verification Form (physical) | Print Form ITR-V; sign in blue ink; post to Centralized Processing Centre, Income Tax Department, Bengaluru 560500 by ordinary or speed post | Taxpayers without Aadhaar linkage or any of the electronic options |
Tax-audit cases must use Digital Signature Certificate For taxpayers covered under section 44AB tax audit, companies, and Limited Liability Partnerships, verification through Digital Signature Certificate is the only permitted mode. Aadhaar One-Time Password and other Electronic Verification Code modes are not accepted for these classes. |
3. The Thirty-Day Window
The thirty-day window runs from the date of e-filing the return, not from the original due date for filing. A return e-filed on 28 July 2026 must be verified by 27 August 2026. A return e-filed on the last day of the extended due date (31 December 2026 for belated returns of Tax Year 2026-27) must be verified by 30 January 2027. Failure to verify within thirty days results in the return being treated as never filed.
Filing Scenario | Verification Deadline | Effect of Late Verification |
|---|---|---|
Original return e-filed on 25 July 2026 | 24 August 2026 | If verified on day 31, the return is treated as un-filed; re-file as belated under sub-section (4) of section 139 |
Belated return e-filed on 28 December 2026 | 27 January 2027 | Same consequence; carry-forward of losses already lost; further re-filing limited |
Updated return under section 139(8A) e-filed on 15 March 2027 | 14 April 2027 | Same; updated returns cannot be re-filed if verification fails |
4. Step-by-Step -- Aadhaar One-Time Password Verification
- Log in to the e-filing portal at the Income-tax Department website using Permanent Account Number and password.
- Navigate to 'e-File' tab, click 'Income Tax Returns', then 'e-Verify Return'.
- Select the Acknowledgement Number of the return to be verified.
- Choose 'Through Aadhaar One-Time Password'.
- Generate the One-Time Password to the mobile number linked to Aadhaar.
- Enter the six-digit One-Time Password within the ten-minute validity.
- Acknowledgement of successful verification is generated -- save in the file.
5. Step-by-Step -- Physical Income Tax Return Verification
- Download the Income Tax Return Verification Form (Form ITR-V) from the e-filing portal.
- Print on A4 paper; sign in original blue or black ink; do not staple.
- Post to: Income Tax Department, Centralized Processing Centre, Bengaluru 560500, by ordinary or Speed Post only -- no courier.
- The signed Form ITR-V should reach the Centralized Processing Centre within thirty days of e-filing.
- Receipt acknowledgement is sent to the registered email; track on the portal.
6. What If Verification Is Missed -- Condonation Request
If the thirty-day window is missed, the only recourse is to file a condonation request under sub-section (4) of section 119 of the Income-tax Act, 1961. The Central Board of Direct Taxes (or the delegated authority -- Commissioner of Income-tax for individuals) may condone the delay if there is genuine hardship. The application is made through the e-filing portal under 'Services' then 'Condonation Request'. Reasons such as illness with medical evidence, technical error documented through screen-shots, or postal delay with despatch proof are considered favourably.
7. Pre-Validate Your Bank Account Today
Pre-validation is the practitioner's first instruction Pre-validate at least one bank account and one demat account at the start of every assessment year, regardless of whether refund is expected. Pre-validation takes 24 to 72 hours -- left to the last week before the deadline, the Bank Account Electronic Verification Code mode becomes unavailable, and the taxpayer is forced into the slower physical Income Tax Return Verification Form route. |
8. Case Law Reference and Anticipatory Legal Analysis
Case Law Reference: Section 139C Income Tax Return verification Section 139C of the Income-tax Act, 1961 (e-verification framework) read with Rule 12 of the Income-tax Rules, 1962 prescribes the verification mechanism for Income Tax Returns -- e-verification via Aadhaar OTP, net-banking, EVC via bank account / demat, or signed ITR-V hard copy. The Income Tax Appellate Tribunal Mumbai in [VERIFY: confirm Tribunal citation on un-verified return treatment] confirmed that an un-verified Income Tax Return is treated as not filed; the section 139(1) due-date deadline applies to verification, not just to filing. [VERIFY: cross-check specific Tribunal citations in the BharatTax case-law database.] |
Prospective Interpretation -- The 30-day verification window Two unsettled interpretive issues. (i) Treatment of the 30-day verification window post-Income Tax Return filing -- effective Tax Year 2022-23, the assessee must verify within 30 days of e-filing. (ii) Treatment of failed verification due to Aadhaar-OTP / net-banking technical issues -- the assessee may use alternative methods. The BharatTax case-law database should monitor emerging Tribunal positions. [VERIFY: confirm Tribunal decisions emerging on the e-verification framework.] |
