To employ your Digitised Account for e-authentication, you need to complete a preliminary validation on the Income Tax e-filing platform. This involves connecting your Digitised Account to your PAN, and ensuring your contact information, especially your mobile number and email address, is up to date. It's vital to highlight that the Digitalised Account should be registered in your name. This condition is of utmost importance as the Electronic Verification Code (EVC) for validating your tax return is sent to the registered contact details, ensuring a secure and personalised verification process.
