If you have already linked your PAN and Aadhaar and want to know the status of the same, follow these steps.
Visit the Income Tax e-filing portal: https://www.incometax.gov.in/iec/foportal/
Click on "Quick Links" on the left side of the page, then select "Link Aadhaar Status".
Enter your 10-digit PAN number and 12-digit Aadhaar number.
Click on "View Link Aadhaar Status".
If your Aadhaar number appears, it means your PAN and Aadhaar cards are already linked.
Otherwise, you'll need to follow the necessary steps to link them.
