<h1>GST Portal Adds Aadhaar and e-KYC Options for Existing Taxpayers; Excludes Government and Statutory Bodies.</h1> A new functionality for Aadhaar Authentication and e-KYC has been implemented on the GST Portal for existing taxpayers as of January 6, 2021. This applies to Regular Taxpayers, including Casual Taxable persons, SEZ Units/Developers, ISD, and Composition taxpayers, but excludes Government Departments, Public Sector Undertakings, Local Authorities, and Statutory Bodies. Taxpayers can authenticate using Aadhaar or, if unavailable, upload alternative documents such as Passport or Voter ID for e-KYC. The process involves navigating to the My Profile section on the portal, where authentication links or document upload options are provided, subject to approval by tax officials.
