Register under GST

The Central Board of Indirect Tax and Customs (CBIC) had issued a notification on 23rd March 2020, making Aadhaar authentication mandatory for GST registration from April 1, 2020. 

What is Aadhaar Authentication?

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 its correctness. The CIDR verifies the correctness of data on the basis of information available with it.

The main purpose behind the Aadhaar authentication is to create an online platform wherein the identity of Aadhaar holders can be validated anytime anywhere. This will keep a check on the malpractices happening under the Goods and Services Tax.

How to do it?

All the applicants submitting registration under GST after 1st of April 2020 shall perform Aadhaar authentication for obtaining registration. An applicant needs to submit an Aadhaar Card along with the application for registration under GST. After this, he needs to e-verify the same on the GST portal. An OTP will be sent on the mobile number and email ID linked to the Aadhaar card. Only upon entering this OTP, the Adhaar will get e-validated.

After this, whenever a taxpayer files his returns or uses any services on the GST portal, an OTP will be sent on the mobile number and email ID, which is linked to its Aadhaar number. Only after entering this OTP, a taxpayer can proceed to file the return.

If a person fails to do an Aadhaar authentication, then the registration will be granted only on physical verification of principal place of business within 60 days from the date of application.

If Aadhaar number is not allotted to a particular individual applying for registration under GST, then an alternate means of identification is made available to him like physical verification of place of business as per the CGST Rules.


The Aadhaar authentication is mandatory for the following class of individuals as per Rule 8 of the CGST Act in order to become eligible for the GST registration:

  1. Authorised signatory of all types
  2. Managing/authorised partners of a partnership firm
  3. Karta of a Hindu Undivided Family


The only exception is if an individual is not a citizen of India or he is a person other than the one mentioned below: 

  1. Individual
  2. Authorised signatory of all types
  3. Managing/authorised partners of a partnership firm
  4. Karta of a Hindu Undivided Family
