Aadhaar OTP is the simplest default for most individual taxpayers and HUFs who have a PAN linked to Aadhaar and can receive an SMS on the mobile number registered with Aadhaar. Choose bank-account EVC if that SMS is unavailable and you already have an active, pre-validated, EVC-enabled bank account. Use a Digital Signature Certificate (DSC) when the rules require a digital signature or you are verifying immediately after filing with a working token; it is not available if you selected “e-Verify Later.”
Whichever method you use, verify the return on time: for returns filed on or after 1 August 2022, the deadline is 30 days from filing. An unverified return is treated as not filed unless the tax authority approves a delay-condonation request.

Why does ITR e-verification matter?
Filing the return is not the final step: verification completes the process. The Income Tax Department says that an ITR not verified within the stipulated time is treated as invalid, and that a return not verified in time is treated as not filed, with the consequences of non-filing under the Income-tax Act, 1961. The department’s e-Verify FAQ describes online verification as the instant route, but you can also send a duly signed paper ITR-V to CPC, Bangalore.
For returns filed on or after 1 August 2022, the Income Tax Department’s 2022 guidance, quoting Notification No. 5/2022 dated 29 July 2022, sets the e-verification or ITR-V submission limit at 30 days from the date of filing. The older 120-day limit continues only for returns filed on or before 31 July 2022. In November 2026, the 30-day clock is the one that applies to current returns, including AY 2026-27 returns filed against a July 2026 due date. The clock runs from your own filing date, not from the general filing deadline.

The FAQ includes a question framed around filing more than 120 days ago, but that wording should not be mistaken for the current rule. If you miss the applicable deadline, the department says you may submit a request to condone the delay, giving an appropriate reason. Its manual’s online flow asks for a reason, and “Others” opens a remarks field. Submitting that request does not by itself make the return valid: according to the FAQ, validity follows only if the competent Income Tax Authority approves it. The department pages cited here do not specify a verification-specific rupee penalty or confirm a particular deemed filing date, so do not assume either.
See the department’s How to e-Verify user manual for the portal flow. If you are close to the 30-day deadline, choose a route whose prerequisites you already meet rather than spending the remaining time setting up an account or token.

Which method should I choose?
For an individual or HUF, start with Aadhaar OTP if the PAN-Aadhaar link is in place and the Aadhaar-registered mobile can receive the message. If that condition fails, bank EVC is the practical fallback only when the bank account is already active, pre-validated, and EVC-enabled. DSC is not a more convenient version of OTP: it involves a token and desktop utility, and the portal offers it only in the immediate post-filing flow.
- Choose Aadhaar OTP if you can receive the message on the mobile registered with Aadhaar and want the fewest setup requirements.
- Choose bank EVC if Aadhaar OTP is unavailable and you can access the mobile and email registered to an eligible bank account.
- Choose DSC if your filing category requires a digital signature, or you already have the working token and intend to verify in the same session as filing.
- If you already selected “e-Verify Later”, do not plan on using DSC for that return. The portal’s later verification flows list other options.
These are practical recommendations based on the department’s requirements, not a ranking published by the department. It has not published a share of returns verified through each method or average completion times. News coverage has called Aadhaar OTP a simple or quick option for many individuals; that describes the lighter prerequisite list, not an official measured speed or usage statistic.
How does Aadhaar OTP work, and what do I need?
Aadhaar OTP is generally the best default for an individual or HUF whose PAN is linked to Aadhaar and who can access the mobile number registered with Aadhaar. The Income Tax Department’s FAQ is explicit: if your mobile number is not updated with Aadhaar, you cannot use Aadhaar OTP until it is updated. Having a different number on your e-filing profile does not substitute for the Aadhaar-registered number.
To verify with Aadhaar OTP:
- On the e-Verify page, choose “I would like to verify using OTP on mobile number registered with Aadhaar,” then click Continue.
- On the Aadhaar OTP screen, select “I agree to validate my Aadhaar Details” and click Generate Aadhaar OTP.
- Enter the six-digit code sent to the Aadhaar-registered mobile and click Validate.
The department’s 2026 user manual says this OTP is valid for 15 minutes and allows three attempts. The screen displays a countdown; if you need another code, use Resend OTP. There is also an “I already have an OTP on Mobile number registered with Aadhaar” option if the code is already in hand, subject to the same expiry and attempt limits.

Do not confuse this with the separate OTP used to get through the pre-login verification gate. Before selecting a method without signing in, you provide your PAN, assessment year, acknowledgement number, and a mobile number, then enter a separate six-digit mobile OTP. That gate OTP also has a 15-minute validity and three-attempt limit, but it is not the Aadhaar OTP that verifies the return.
Aadhaar OTP is available in the immediate filing flow and in pre-login or post-login “verify later” flows. It does not depend on prior bank-account validation or a USB token. That makes it a useful first choice for an individual taxpayer, but it cannot solve a missing or inaccessible Aadhaar-registered mobile number.
When is bank-account EVC a better choice?
Bank-account EVC is a suitable alternative if you cannot receive Aadhaar OTP and already have an eligible account. The account must be active, pre-validated on the e-filing portal, and EVC-enabled. The code is sent to the mobile number and email registered with the bank, which may differ from both your Aadhaar mobile and the number on your e-filing profile.
To use it, select Through Bank Account on the e-Verify page and click Continue. The portal generates the Electronic Verification Code and sends it to the bank-registered contact details. Enter the code and click e-Verify. The manual also provides an “I already have an Electronic Verification Code (EVC)” path for a code you have already received.
The Income Tax Department’s FAQ defines an EVC as a 10-digit alphanumeric code and says it is valid for 72 hours from generation. It does not state in the material cited here that bank EVC is single-use, so do not rely on that as a rule. The department pages state no fee for this route.
Pre-validation is the main catch. If you have never enabled EVC for the bank account, the setup step may delay you, and an inactive account will not work. If you already filed and the deadline is approaching, use a method available now or another official route rather than assuming a new bank setup will be immediate. The parallel demat-account EVC route works through an active, pre-validated, EVC-enabled demat account, with the code sent to the mobile and email registered there.

When should I use a Digital Signature Certificate?
Use DSC when the applicable filing rule requires a digital signature, or when you already have the required token and are verifying immediately after filing. It is not a general-purpose option to return to later: the department’s FAQ says you cannot select DSC if you chose “e-Verify Later” while submitting the return.
The user manual lists these prerequisites:
- A valid and active DSC.
- A DSC USB token, procured from a Certifying Authority provider; the manual describes it as a Class 2 or Class 3 certificate.
- The emSigner utility installed and running on the PC.
- The USB token plugged into that PC.
The manual does not specify a token price, certificate validity term, brand, or preferred Certifying Authority. The department pages do not give a rupee fee for DSC. Do not assume a generic USB device is sufficient: the stated requirement is a token carrying the DSC procured from a Certifying Authority.
Recommended Free Tools
In the filing session, choose “I would like to e-Verify using Digital Signature Certificate (DSC).” On the identity screen, download the emSigner utility if needed, install it, select “I have downloaded and installed emsigner utility,” and click Continue. On the Data Sign page, select the provider and certificate, enter the provider password, and click Sign. A successful flow produces a confirmation and Transaction ID; the manual says confirmation is sent to the mobile and email registered on the e-filing portal.
The most important timing distinction is that DSC appears in the immediate verification route, not in the manual’s pre-login or post-login “verify later” method lists. Those lists include Aadhaar OTP, existing Aadhaar OTP, existing EVC, bank and demat account methods, and ATM; post-login also includes net banking. If you need a return verified later, choose one of those available routes instead of expecting the token to remain an option.
Does the law require DSC for my type of filer?
Not for every filer. The choice is partly procedural, but the applicable Rule 12 filing manner can make a digital signature mandatory for some categories. In particular, do not assume that every audited individual must use DSC.
For an individual or HUF whose accounts are required to be audited under section 44AB, the Central Board of Direct Taxes’ Notification No. 19/2024 (G.S.R. 83(E)), dated 31 January 2024 and effective 1 April 2024, provides two electronic manners: digital signature or electronic verification code. The change is reproduced in TaxGuru’s account of the Rule 12 amendment and summarized by Taxmann. For these individuals and HUFs, EVC is an available alternative; DSC is not automatically the only permitted method.

The department’s indexed Rule 12 table states that a company must furnish its return electronically under digital signature in all cases. The same indexed table specifies digital signature for a political party filing ITR-7. The direct Rule 12 page did not open on a direct fetch on 13 November 2026, so this company and political-party description is attributed to the indexed department table. A political-party return should not be confused with every ITR-7 return; the indexed extract lists other ITR-7 filers with different permitted manners.
The manner for a firm or LLP under section 44AB cannot be resolved confidently from the available complete official text: the indexed Rule 12 extract identifies the relevant ITR-5 conditions but cuts off before the manner column. A firm or LLP under audit should confirm the current Rule 12(3) serial 4 requirement with the department or its chartered accountant before relying on Aadhaar OTP or bank EVC. Do not extend the individual/HUF amendment to firms, and do not treat an incomplete table extract as proof that a firm must use DSC.
Rule 12 describes an electronic verification code in terms of a code generated under the systems department’s data structure and standards. “Aadhaar OTP” is the portal FAQ’s name for one of the available verification methods; do not present that exact phrase as wording in the statute.
What if I cannot receive Aadhaar SMS, or I am an NRI?
The department’s rule for Aadhaar OTP turns on access to the mobile registered with Aadhaar, not on nationality. Its FAQ does not provide a separate NRI exception: if the number is not updated with Aadhaar, Aadhaar OTP is unavailable until it is. An NRI who cannot receive that SMS should check whether an eligible bank EVC route is available, or consider another official route.

Those are practical observations from that guide, not additional department rules. The underlying portal requirements remain decisive: bank EVC goes to the bank-registered mobile and email, while DSC requires a token, emSigner on a PC, and immediate verification after filing.
If the mobile linked to Aadhaar is old, repeatedly requesting OTPs will not fix the mismatch; update that number with Aadhaar or switch methods. If the bank contact details are also inaccessible, consider demat EVC, net banking after logging in, or a supported bank ATM route if its requirements fit. The department’s help pages list no guarantee that an overseas phone will receive an Indian bank’s SMS, so check access to the registered destination before relying on that channel.

What other official verification methods are available?
The three methods above are not the only routes. The department also lists demat-account EVC, net banking, bank-ATM EVC, and signed paper ITR-V. These alternatives matter if Aadhaar OTP or bank EVC is not workable.
- Demat EVC: Requires an active demat account that is pre-validated and EVC-enabled on the e-filing portal. The EVC is sent to the mobile number and email registered with that demat account.
- Net banking: The manual says PAN must be linked with the bank account and net banking must be enabled. Select Through Net Banking, choose the bank, accept the disclaimer, sign in on the bank’s website, and follow the link back to the e-filing dashboard to verify the return. This route is available after logging in; the manual section cited here does not provide an approved-bank count.
- Bank ATM EVC: This is not available at any ATM. The department manual names seven participating banks: Axis Bank Ltd, Canara Bank, Central Bank of India, ICICI Bank, IDBI Bank, Kotak Mahindra Bank, and State Bank of India. The PAN must be linked to the bank account and match the PAN on the e-filing portal. The EVC is sent to the mobile and email registered on the e-filing portal; enter it using the existing-EVC option.
- Paper ITR-V: You may send a duly signed ITR-V to CPC, Bangalore. e-Verification avoids waiting for postal transit, but paper submission remains an official route. The FAQ material cited here does not provide a street address or PIN, so confirm the current dispatch details on the department portal rather than relying on an address from an old guide.
For pre-login verification, the department FAQ says you need your PAN, assessment year, and acknowledgement number. After logging in, the portal lets you select the filed return; the manual’s path is e-File > Income tax return > e-Verify Return, then choose e-Verify against the unverified return.

Look for the success message and keep the Transaction ID. The department FAQ says a confirmation email is sent to the email registered on the e-filing portal. The user manual also describes a confirmation to the registered mobile and email; when using an existing EVC, it advises noting the EVC as well. If a message does not appear, check the return’s status in the portal rather than assuming that merely generating an OTP or EVC completed verification.
If an ITR-V is rejected, the FAQ says it can be resent or replaced by online e-verification. If the applicable verification window has already passed, the delay-condonation process applies; the return is treated as valid only after the competent authority approves the request. For e-filing and CPC questions, the help pages displayed 1800 103 0025, 1800 419 0025, +91-80-46122000, and +91-80-61464700, with hours listed as 08:00 to 20:00 Monday through Friday when checked on 13 November 2026.
How to make the decision before the deadline
- Check the legal filing manner first. A company, for example, is shown in the indexed Rule 12 table as requiring digital signature. Individual and HUF taxpayers under section 44AB can use EVC or DSC from 1 April 2024. If you are a firm or LLP under audit, confirm the applicable row rather than guessing.
- Check whether you selected “e-Verify Later.” If you did, DSC is unavailable for that return in the later flow.
- Check the contact destination. Aadhaar OTP goes to the Aadhaar-registered mobile; bank EVC goes to the bank-registered mobile and email. The two need not match.
- Use an already enabled route. Bank EVC depends on account pre-validation and EVC enablement; DSC depends on the valid token, emSigner, and PC. Avoid making a new setup your only plan near the deadline.
- Complete verification and confirm the status. Save the Transaction ID and check that the return is shown as verified.
The practical default is therefore Aadhaar OTP for an eligible individual or HUF, bank EVC when Aadhaar SMS is the obstacle and the account is ready, and DSC only where the rules or same-session circumstances call for it. The deadline and the filer’s Rule 12 category matter more than which method sounds fastest.
Frequently Asked Questions
Can an authorized signatory or representative verify an ITR for someone else?
Yes. The Income Tax Department FAQ says an authorized signatory or representative assessee may e-verify on the assessee’s behalf. The OTP or EVC is sent according to the contact details associated with that representative and the selected route; this does not replace a digital signature where the filer’s category requires one.

The e-Verify user manual lists PAN-Aadhaar linkage as a prerequisite for the Aadhaar OTP method. If that condition is not met, use another eligible route rather than treating an OTP sent to an Aadhaar mobile as sufficient.
What happens if I mailed ITR-V but CPC says it was not received?
The department FAQ says you may e-verify online instead of resending a rejected physical ITR-V. If the applicable verification period has already passed, submit a condonation request first; the return is not treated as valid until that request is approved.
Can I use an ATM EVC from any bank?
No. The department manual limits the ATM EVC option to seven named banks and requires the PAN to be linked to the bank account and to match the PAN on the e-filing portal. The EVC is sent to the contact details registered on the e-filing portal.
