Aadhaar-PAN Linking: How to Fix Mismatched Details Before December 31, 2025

The deadline to link your Aadhaar with PAN is fast approaching, and missing it could lead to serious consequences, including the PAN becoming inoperative. If you’ve tried linking your Aadhaar and PAN but encountered an error due to mismatched details, don’t panic. Fixing it is easier than you think. This article will guide you through everything you need to know to ensure your Aadhaar-PAN linking is smooth and hassle-free before December 31, 2025.


Why Linking Aadhaar and PAN is Important

The Income Tax Department of India mandates linking Aadhaar and PAN to:

  • Prevent tax evasion and duplicate PANs
  • Make tax filing simpler and faster
  • Ensure you receive tax refunds without delays

If your PAN is not linked with Aadhaar by the deadline, you may face:

  • PAN deactivation
  • Inability to file income tax returns
  • Legal complications for future financial transactions

Hence, addressing mismatched details before December 31 is critical.


Common Reasons for Mismatched Aadhaar-PAN Details

Errors often occur during the linking process due to:

  1. Name Mismatch – Differences in spelling, initials, or name format between PAN and Aadhaar.
  2. Date of Birth Mismatch – Variations in date, month, or year.
  3. Gender Mismatch – Incorrect gender entries in PAN or Aadhaar records.

Even minor differences, like “Ramesh Kumar” vs “RAMESHKUMAR,” can cause an error.


Step-by-Step Guide to Fix Mismatched Details

Here’s how to resolve the issue:

Step 1: Verify Your Details

  • Check the name, date of birth, and gender on both your Aadhaar and PAN.
  • Make sure the details match exactly. Pay attention to spelling, initials, and format.

Step 2: Correct Aadhaar Details (If Required)

If your Aadhaar has incorrect information:

  1. Visit the UIDAI official website: https://uidai.gov.in
  2. Click on “Update Aadhaar Details”
  3. Choose the field that needs correction – name, date of birth, or gender
  4. Submit scanned documents supporting the change
  5. Receive an update acknowledgment number for tracking

Tip: Name changes require legal documents like a marriage certificate or Gazette notification.

Step 3: Correct PAN Details (If Required)

If your PAN details are incorrect:

  1. Visit the NSDL e-Gov PAN website: https://www.tin-nsdl.com
  2. Click on “Correction/Update PAN Data”
  3. Fill in the corrected details exactly as per Aadhaar
  4. Upload supporting documents and submit the request

Step 4: Link Aadhaar with PAN

Once details are corrected:

  1. Go to the Income Tax e-Filing website: https://www.incometax.gov.in
  2. Click on “Link Aadhaar”
  3. Enter PAN, Aadhaar number, and name
  4. Submit and wait for the confirmation message

You should see a success message indicating your Aadhaar and PAN are now linked.


Alternative Method: Linking via SMS

If you prefer a simpler method, you can link Aadhaar and PAN via SMS:

  • Type: UIDPAN<space><12-digit Aadhaar><space><10-digit PAN>
  • Send to: 567678 or 56161
  • If details match, you’ll receive a confirmation SMS

This method is convenient but requires matching details on both Aadhaar and PAN.


Things to Keep in Mind

  • Deadline: December 31, 2025. Don’t wait until the last moment.
  • Exact Match: Even small spelling differences can cause a mismatch.
  • Check Status: You can verify if PAN-Aadhaar linking is successful on the Income Tax e-Filing portal.
  • No Fees: Linking PAN with Aadhaar is free of charge.

Common Mistakes to Avoid

  1. Ignoring middle names or initials in PAN or Aadhaar.
  2. Entering wrong year of birth during linking.
  3. Waiting until the last week before December 31 – websites may slow down due to heavy traffic.

Final Thoughts

Linking Aadhaar with PAN is a mandatory step for every taxpayer in India. Mismatched details are a common hurdle, but with the correct steps, you can fix them quickly. By following the steps above, you can ensure your PAN remains active, avoid last-minute stress, and continue enjoying smooth financial and tax-related services.
