How to link an Aadhaar card to a PAN card?

To link your Aadhaar card to a PAN card online, visit the Income Tax e-filing portal and click on the Link Aadhaar option under Quick Links. Enter your PAN and Aadhaar numbers, validate the details, and pay the required fee of 1,000 rupees if applicable. Alternatively, you can link them via SMS by sending UIDPAN followed by your 12-digit Aadhaar and 10-digit PAN to 567678 or 56161. Ensure that your name, date of birth, and gender match on both documents for a successful linkage.
