If you received your PAN card using an Aadhaar enrolment ID, you need to update your records with your actual Aadhaar number by December 31, 2025. The Income Tax Department, via a new notification from the Central Board of Direct Taxes (CBDT), has made this mandatory to ensure accurate linking and data verification.
This rule applies to anyone who was issued a PAN using Aadhaar Enrolment ID before October 1, 2024. The Aadhaar enrolment ID is the temporary number you get when you apply for an Aadhaar card, before receiving the actual Aadhaar number. Now, if your PAN was issued using that temporary ID, you must replace it with your full Aadhaar number in the Income Tax records.
What Is The Main Purpose Of This Pan Update?
The government is working to ensure transparency and reduce duplication in tax records. Linking PAN and Aadhaar allows smoother verification, better tracking of financial transactions, and prevention of tax evasion.
If you fail to update your Aadhaar number by the deadline, your PAN could become inoperative starting January 1, 2026. This means you won't be able to File income tax returns (ITR), Claim refunds

Get proper credit for TDS/TCS, Submit Forms 15G/15H and Carry out transactions where PAN is mandatory. Also, TDS and TCS may be deducted at a higher rate, and your filed ITR may even become invalid.
Who Needs to Update?
Only those PAN holders who got their PAN cards using the Aadhaar enrolment ID (not the actual Aadhaar number) before October 1, 2024 are required to update. Others who have already linked their PAN and Aadhaar earlier don't need to worry.
How to Update Aadhaar Number with PAN?
There are two main ways to do this both online and offline:
1. Online through the Income Tax Portal:
Step 1: Visit www.incometax.gov.in
Step 2: Click on "Link Aadhaar"
Step 3: Enter your PAN and Aadhaar number
Step 4: Verify using OTP received on your Aadhaar-linked mobile number.
Step 5: Submit and keep a screenshot for your records
2. Offline through PAN Service Centres:
Step 1: Visit an authorized NSDL eGov or UTIITSL PAN service centre
Step 2: Fill out the Aadhaar update form
Step 3: Attach a copy of your PAN card and Aadhaar card
Step 4: Pay the applicable fee (if any)
Step 5: If there's a mismatch in data, biometric verification may be required
Will There Be a Penalty For Defaulters?
As of now, there's no penalty announced for these specific PAN holders. This is different from the ₹1,000 fine imposed on general taxpayers who missed the earlier PAN-Aadhaar linking deadline of June 30, 2023. However, more clarity may be issued by the Income Tax Department soon. So in order to avoid unnecessary issues like delayed refunds, inoperative PAN, and invalid ITRs, make sure to update your Aadhaar number with the Income Tax Department by December 31, 2025. It's a simple step that can save you from a lot of financial and legal headaches later.
