<h1>GST Registration in Tamil Nadu & Himachal Pradesh Now Requires Biometric Aadhaar Authentication per Rule 8 Amendment.</h1> Recent updates to the GST registration process in Tamil Nadu and Himachal Pradesh now require applicants to undergo Biometric-based Aadhaar Authentication and document verification. Rule 8 of the CGST Rules, 2017 has been amended to facilitate this. Applicants will receive an email with a link for either OTP-based Aadhaar Authentication or for booking an appointment at a GST Suvidha Kendra (GSK) for biometric verification. At the GSK, applicants must present their Aadhaar and PAN cards, along with original documents uploaded during the application. This process aims to enhance security and streamline verification.
