If Income Tax Aadhaar OTP is not working, first identify whether the problem is OTP delivery, OTP validation, login, or a specific e-Filing workflow. An Aadhaar OTP error does not automatically mean the entire Income Tax portal or UIDAI is down.
Direct answer
If no OTP arrives, verify that you have access to the mobile number registered with Aadhaar and that the prerequisites for the service are satisfied. If the OTP arrives but validation fails, check its age, whether a newer OTP replaced it and the exact error displayed. For applicable Income Tax e-verification workflows, official alternatives can include bank or demat EVC, Net Banking, Bank ATM EVC and DSC.
Do not assume those alternatives replace Aadhaar authentication in every Income Tax service. The options available depend on the exact workflow and your account eligibility.
1. Check whether the whole Income Tax portal is down
The public Income Tax e-Filing portal was accessible during the September 8, 2026 review and continued to expose normal taxpayer services and current filing information.
That does not prove every authenticated service is working for every taxpayer, but it is an important boundary: if the homepage and login environment are available while one Aadhaar-dependent action fails, the evidence supports investigating that specific verification step before calling it a complete portal outage.
Do not report “UIDAI down” or “Income Tax portal down” from one Aadhaar OTP error. The visible error does not establish which backend component caused the failure.
2. Aadhaar OTP is not arriving
For Income Tax Aadhaar OTP verification, the code is sent to the mobile number registered with Aadhaar. For e-verification using Aadhaar OTP, the official Income Tax documentation also requires PAN to be linked with Aadhaar.
Before generating another OTP, check:
- whether you still have access to the mobile number registered with Aadhaar;
- whether PAN and Aadhaar are linked where the workflow requires it;
- whether mobile network or SMS delivery is delayed;
- whether an OTP arrived after you requested another one;
- whether the screen is actually waiting for Aadhaar OTP rather than an e-Filing OTP or another verification code.
If nothing arrives after a reasonable retry, preserve the exact workflow, time and error rather than repeatedly generating codes.
3. OTP arrived but Income Tax says it is invalid
The official Income Tax e-Verify documentation states that an Aadhaar OTP is valid for 15 minutes and allows three attempts to enter the correct OTP.
Requesting another OTP creates a new code, so an earlier code should not be assumed to remain usable.
- Use the most recently generated OTP.
- Enter it within the displayed validity period.
- Check for mistyped digits.
- Avoid repeated resend requests while testing the same code.
- If validation still fails, save the exact error message.
4. You see a UIDAI or Aadhaar authentication error
An Aadhaar-related error inside the Income Tax portal does not by itself identify the technical root cause. The failure can occur at different points in the authentication or integration path.
The September 8 review did not identify a controlling Income Tax Department or UIDAI public notice establishing a nationwide Aadhaar OTP outage.
Reader rule: describe what your screen proves. If your Income Tax Aadhaar verification failed, that is established. A nationwide UIDAI outage is not established unless the competent authority or sufficiently broad evidence confirms it.
5. Can you e-Verify an ITR without Aadhaar OTP?
Yes, potentially. Income Tax officially supports several methods for e-verification, depending on the taxpayer and the exact process.
| Verification method | Officially supported for applicable e-verification? | Main prerequisite |
|---|---|---|
| Aadhaar OTP | Yes | PAN linked with Aadhaar and access to the Aadhaar-registered mobile number |
| Bank Account EVC | Yes | Validated and EVC-enabled bank account |
| Demat Account EVC | Yes | Validated and EVC-enabled demat account |
| Net Banking | Yes | PAN-linked eligible bank account with Net Banking enabled |
| Bank ATM EVC | Yes, through supported banks | Eligible participating bank and debit-card route |
| Digital Signature Certificate | Yes where applicable | Valid DSC and required signing setup |
Alternative e-verification method does not mean universal Aadhaar bypass. A method available for e-verifying an ITR may not replace Aadhaar authentication in a different profile, login or service-specific workflow.
6. Aadhaar OTP fails while adding or validating a bank account
Income Tax’s current My Bank Account documentation shows that adding and validating a bank account can offer different e-verification methods depending on the user login type.
The documented methods can include:
- Aadhaar-registered mobile OTP;
- Bank Account or Demat Account EVC;
- Net Banking; and
- DSC.
That means a bank-account workflow may offer an alternative when Aadhaar OTP fails, but you should use only the options displayed for your account and service.
Do not infer that every Income Tax bank, profile or Aadhaar-linked action supports the same alternatives.
7. Know when to stop retrying
If the same error keeps appearing, repeated OTP generation can make troubleshooting harder because newer codes replace older ones and the final state becomes less clear.
After one careful retry:
- take a screenshot of the full error;
- note the date and time;
- record the exact Income Tax service you were using;
- save any transaction or acknowledgement number;
- check whether an officially supported alternative exists for that exact workflow;
- use official support if the problem continues.
What if Aadhaar OTP is required for Income Tax login?
The Income Tax login manual confirms that Aadhaar OTP can be used as a login verification method, including where the e-Filing Vault higher-security option is enabled.
If your account is configured to require Aadhaar OTP for higher-security login, an alternative that exists for ITR e-verification should not automatically be assumed to bypass that login requirement.
Check the account’s configured higher-security method and official login guidance.
What if Aadhaar OTP fails during password reset?
The official password-reset workflow supports several methods depending on the account and configuration, including Aadhaar OTP, e-Filing OTP, Bank Account EVC, Demat Account EVC, DSC and Net Banking.
If your screen exposes another permitted method, follow the current official workflow rather than repeatedly generating Aadhaar OTPs.
How to generate an EVC instead
For eligible individual taxpayers, Income Tax provides an Electronic Verification Code service.
EVC can be generated through supported routes such as a validated and EVC-enabled bank account or demat account, and official documentation also provides Net Banking and supported Bank ATM routes for relevant verification tasks.
Whether EVC solves your problem depends on the exact action you are trying to complete.
When should you contact Income Tax support?
Escalate when the same verified workflow continues to fail, especially if the action is deadline-sensitive and no supported alternative is available.
The current Income Tax Contact Us page lists e-Filing and Centralized Processing Center support from 08:00 to 20:00, Monday to Friday, including:
- 1800 103 0025;
- 1800 419 0025;
- +91-80-46122000; and
- +91-80-61464700.
Verify the latest contact details on the official portal before calling because support information can change.
What evidence should you preserve?
- the exact Income Tax workflow;
- date and time of the failed attempt;
- full error text or screenshot;
- whether the OTP never arrived or arrived but failed validation;
- whether a newer OTP had already been requested;
- transaction or acknowledgement number if generated;
- any deadline connected with the failed action;
- support or grievance acknowledgement if escalated.
Does an Aadhaar OTP failure extend an Income Tax deadline?
No automatic deadline extension should be assumed. A technical failure, OTP delay, support call or screenshot does not itself extend a statutory or communication-specific deadline.
If a deadline-sensitive action fails, preserve evidence and use the official support or grievance route promptly.
What the August 11, 2026 reports established
The original version of this article was published after users reported Aadhaar OTP and UIDAI-related errors during Income Tax workflows on August 11, 2026.
Subsequent TPS reviews did not identify an official nationwide outage acknowledgement or a material change to the Aadhaar OTP and alternative verification framework.
The durable reader problem is therefore not whether that one August incident is still live. It is how to diagnose an Aadhaar OTP failure correctly and choose the next valid verification route without assuming a nationwide outage.
Verification method
ThePulseSignal checked the current Income Tax e-Filing homepage, e-Verify manual, login manual, My Bank Account documentation, EVC guidance and Contact Us page on September 8, 2026. UIDAI’s current public portal was also checked for a controlling nationwide OTP-outage advisory. The current official Income Tax documentation continues to support Aadhaar OTP and multiple alternative verification methods for applicable workflows.
Limitations and unresolved facts
- TPS cannot test a private taxpayer’s Aadhaar OTP, mobile delivery or authenticated Income Tax account.
- The absence of a nationwide outage notice does not prove that no individual or regional OTP failure exists.
- The exact root cause of a taxpayer’s OTP failure cannot be determined from a generic error message alone.
- Verification alternatives vary by workflow, account type, bank eligibility and security configuration.
- A method available for ITR e-verification may not replace Aadhaar authentication for another service.
- Income Tax and UIDAI can change authentication workflows, support routes or prerequisites.
Income Tax Aadhaar OTP not working: FAQs
Is the Income Tax portal down if Aadhaar OTP fails?
No. An Aadhaar OTP failure does not by itself prove that the entire Income Tax portal is down.
Is UIDAI down if Income Tax shows an Aadhaar error?
Not necessarily. The visible error does not establish which system caused the failure.
How long is an Income Tax Aadhaar OTP valid?
The official e-Verify manual states that Aadhaar OTP is valid for 15 minutes and allows three attempts.
Can I e-Verify my ITR without Aadhaar OTP?
Potentially yes. Official alternatives include eligible bank or demat EVC, Net Banking, supported Bank ATM EVC and DSC.
Can I use the same alternatives for every Income Tax service?
No. The available verification methods depend on the exact service and your account eligibility.
Should I keep requesting new Aadhaar OTPs?
No. If the same failure persists, perform one careful retry, preserve the error and use an alternative or official support where appropriate.
Can bank-account validation use another method?
The current My Bank Account documentation supports several verification methods depending on login type, including Aadhaar OTP, EVC, Net Banking and DSC.

Bottom line: treat Income Tax Aadhaar OTP failure as a specific verification problem until broader evidence proves otherwise. Check whether the OTP is being delivered or rejected, use only the alternative verification methods supported by your exact workflow, preserve evidence if the failure persists and avoid repeated OTP generation that makes the current code state unclear.
