Introduction
The Goods and Services Tax Network (GSTN) has strengthened the GST registration process by introducing biometric-based Aadhaar authentication and document verification for selected applicants as part of its risk-based registration framework.
Businesses applying for GST registration in Bihar may now be required to undergo biometric Aadhaar authentication at a designated GST Suvidha Kendra (GSK) before their registration application is processed.
This article explains the GST registration process in Bihar, when biometric authentication is required, the documents needed, and the step-by-step procedure for obtaining GST registration in 2026.
What is Biometric Aadhaar Authentication?
Biometric Aadhaar Authentication is an identity verification process where the applicant's Aadhaar details are verified using biometric information such as fingerprints, facial photograph, or iris authentication (as applicable), along with verification of original documents at a designated GST Suvidha Kendra (GSK).
