How to link an Aadhaar card with a PAN card?

You can link your Aadhaar with your PAN card online through the Income Tax e-filing portal. Visit the official website, click on the Link Aadhaar option, and enter your PAN and Aadhaar number. After validating your details and paying the applicable fee of 1,000 rupees, you can submit the linking request. Alternatively, you can link them by sending an SMS in the format UIDPAN <12-digit Aadhaar> <10-digit PAN> to 567678 or 56161, or by visiting a designated PAN service centre.
