how to change mail id in pan card

To change your email ID on your PAN card, you must apply for a "Changes or Correction in existing PAN Data" using the official Protean (formerly NSDL) or UTIITSL portals. On either website, select the change request option, fill the application form with your new email ID, and submit it, ensuring you select the relevant correction box. Alternatively, registered users can update their contact details, including the email ID, through the 'My Profile' section after logging into the Income Tax e-Filing portal.
