Aadhaar authentication under GST

Aadhaar authentication is a process by which the Aadhaar number along with other biometric details of the Aadhaar holder are submitted to the Central Identities Data Repository (CIDR) for verifying the user.

Aadhaar Authentication process has been introduced under GST law with effect from 21.08.2020 for the persons applying for GST registration as Normal Taxpayer/ Composition/ Casual Taxable Person/ Input Service Distributor (ISD)/ SEZ Developer/ SEZ Unit etc.

Applicants, who, either do not provide Aadhaar, while applying for new registration or whose Aadhar authentication fails in validation, would be subjected to site verification by the tax department. However, tax authority based on the documents produced can grant registration.

How Aadhaar authentication is done?

  • Once registration application is submitted, an authentication link will be shared on GST registered mobile numbers and email ids mentioned in the GST application

  • Taxpayer need to complete Aadhaar authentication of all Promoters/ Partners/ Authorized Signatories/ Karta etc. as mentioned in the application to avail this option
  • On successful authentication, the demographic data of the persons is taken from the Aadhaar to the GST system.

Applicant can access the link again for authentication by navigating to My Saved Applications > Aadhaar Authentication Status > Resend Verification Link. Persons who are not resident /citizen of India are exempted from the Aadhaar authentication process
