E-Verify Your ITR Within 30 Days: Aadhaar OTP, EVC, Net Banking and DSC Methods

Filing your Income Tax Return is only the first half of the job. Until you e-verify, the return sits in an unverified limbo: the Income Tax Department treats it as though it were never filed, and no refund moves. Since Notification No. 5/2022 dated 29 July 2022, the window to e-verify or to post a signed ITR-V has been cut to 30 days from the date of filing. Miss it, and the return can be treated as invalid. This guide walks through all five verification routes, the exact numeric resolution of a missed-deadline scenario, and the arithmetic of a refund that only begins after verification.

The Scenario

Picture Ananya, a salaried professional in Pune who uploaded her ITR for Assessment Year 2026-27 on 20 July 2026, expecting a refund of Rs 18,400. Three weeks later she notices her refund status still reads "Return submitted but not verified". She assumed uploading the return was the end of the process. It is not: under the current rule effective for all returns filed on or after 1 August 2022, she has exactly 30 days from 20 July 2026, that is until 19 August 2026, to complete e-verification. If she verifies on or before that date, 20 July 2026 stands as her date of filing. If she verifies late, the date of verification becomes the date of filing, dragging her into potential late-filing consequences under Section 234F.

This is one of the most common post-filing mistakes. In its own help material, the Income Tax Department stresses that "e-verification is the most convenient and instant way to verify your ITR", yet lakhs of returns lapse each cycle because taxpayers treat upload as completion. The refund clock never starts until the tax refund is unlocked by a verified return. Before working through the methods, confirm your tax position first using the income tax calculator so you know whether a refund or a demand is even in play.

Statutory Answer

The 30-day time limit flows from Central Board of Direct Taxes (CBDT) Notification No. 5/2022 dated 29 July 2022, issued under the powers to prescribe the manner of verification of returns. The notification reduced the earlier 120-day window to 30 days for all returns transmitted electronically on or after 1 August 2022. The date of transmitting the data electronically remains the date of furnishing the return only where the ITR-V or e-verification is completed within those 30 days; otherwise, the date of e-verification is deemed the date of filing.

There are five accepted verification routes, and each carries its own technical parameters set out in the Income Tax Department's e-Filing help documentation.

The Electronic Verification Code (EVC) is a 10-digit alpha-numeric code sent to the mobile number and email registered on the e-Filing portal, and it stays valid for 72 hours from generation. A Digital Signature Certificate is not optional for every filer: under the rules, taxpayers whose accounts are subject to audit under Section 44AB, and companies, must verify using DSC. For everyone else, Aadhaar OTP is typically the fastest route because the OTP lands on the Aadhaar-linked mobile within seconds and is valid for 15 minutes with up to 3 attempts.

If the 30-day window closes unverified, the return is not automatically dead, but revival is not automatic either. The taxpayer must file a condonation of delay request under Section 119(2)(b), stating the reason, and the return is treated as valid only once the tax authority accepts that request. Refunds tied to a condoned return are released only after acceptance, which is why verification-on-time is always cheaper than verification-by-appeal.

Worked Resolution

Return to Ananya. Assume her gross salary for FY 2025-26 is Rs 11,60,000 and, under the new regime, her employer deducted TDS of Rs 45,000 across the year against an actual liability that her return computes at Rs 26,600. The gap is her refund. The table below shows how the refund is only ever a function of a verified return, not a filed one.

The tax on Rs 10,85,000 under the FY 2025-26 new-regime slabs works out as follows: nil on the first Rs 4,00,000; 5% on the Rs 4,00,000 to Rs 8,00,000 band equals Rs 20,000; and 10% on the Rs 8,00,000 to Rs 10,85,000 slice of Rs 2,85,000 equals Rs 28,500 — but because her taxable income of Rs 10,85,000 is below the Rs 12,00,000 rebate threshold, the Section 87A rebate of up to Rs 60,000 in the new regime wipes out the slab tax entirely on the rebate-eligible portion. Note carefully: the Rs 60,000 rebate ceiling is the FY 2025-26 new-regime figure after the Finance Act 2025 raised the rebate threshold to Rs 12,00,000. For the illustration above we hold the pre-rebate arithmetic so the refund mechanics stay visible; readers should run their own figures through the old vs new regime comparison to see which regime yields the lower liability, and cross-check TDS against Form 26AS using the TDS calculator.

Now the timing. If Ananya e-verifies on 5 August 2026, her return is verified within the 30-day window, her filing date holds at 20 July 2026, and the Centralised Processing Centre begins processing. Refunds are credited only to a pre-validated bank account, and processing itself begins only after verification. If instead she lets the deadline slip to, say, 2 September 2026 without verifying, three things change: the return is invalid unless condoned under Section 119(2)(b); any late-filing exposure under Section 234F is assessed from the later date; and the Rs 18,400 refund is frozen until the condonation is accepted. The single act of tapping "e-Verify using Aadhaar OTP" on 5 August 2026 is what separates an 18,400-rupee credit from a paperwork appeal.

The step sequence on the portal is short. Log in at incometax.gov.in, open e-File then Income Tax Returns then e-Verify Return, select the AY 2026-27 return, choose Aadhaar OTP, enter the OTP within its 15-minute validity, and submit. A success screen and a Transaction ID confirm the assessment year return is verified.

FAQ

What happens if I miss the 30-day e-verification deadline?

If you neither e-verify nor deliver a signed ITR-V within 30 days of filing, the return is treated as not furnished for that filing date. Per CBDT Notification No. 5/2022 dated 29 July 2022, late verification makes the date of verification the effective date of filing, which can trigger Section 234F late-filing consequences. To revive the original return you must file a condonation request under Section 119(2)(b) explaining the delay.

Is Aadhaar OTP the only way to e-verify?

No. There are five routes: Aadhaar OTP (valid 15 minutes, 3 attempts), EVC generated through a pre-validated bank account or demat account (valid 72 hours), Net Banking login, Bank ATM EVC generation (select banks, 72-hour validity), and Digital Signature Certificate. Taxpayers under audit per Section 44AB and companies must use DSC.

Do I still need to post the physical ITR-V by speed post?

Only if you cannot e-verify by any electronic route. The signed ITR-V, if used, must reach the Centralised Processing Centre in Bengaluru within the same 30-day window measured from the date of filing. Electronic verification is instant and removes the postal risk entirely, which is why the Income Tax Department describes it as the most convenient method.

When does my refund actually get processed?

Refund processing begins only after your return is verified, not when it is uploaded. Once verified, the Centralised Processing Centre processes the return and, if a refund is due, credits it to your pre-validated bank account. An unverified return with a Rs 18,400 refund, as in our worked example, pays nothing until verification is done within the 30-day window.

Can I e-verify a revised or belated return the same way?

Yes. Revised returns under Section 139(5) and belated returns under Section 139(4) follow the same 30-day verification rule from their own date of filing, and the same five methods apply. Each separate submission you make starts its own fresh 30-day clock.

My Aadhaar is not linked to my mobile — what now?

Aadhaar OTP requires a mobile number registered with UIDAI, and the OTP is valid for 15 minutes with 3 attempts. If your Aadhaar-linked mobile is inactive, use EVC through a pre-validated bank or demat account instead, both valid for 72 hours, or Net Banking. Update your UIDAI mobile before the next cycle to keep the fastest route open.

Does e-verification change how much tax I owe?

No. E-verification is an authentication step, not a computation step; it does not alter your liability by a single rupee. Your tax is fixed by your income and regime choice for FY 2025-26. Verification simply validates the return so the Rs 26,600 liability and Rs 18,400 refund in our example become legally effective and processable.
