Register under GST

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

The same has been amended vide notification 62/2020 dated 20th August 2020 to be made optional. The aadhaar authentication for GST registration is not required for non-residents, persons other than citizens of India and persons who have already been registered under GST.

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.

GST law on Aadhaar Authentication for GST registration

As per the latest notification, every applicant for GST registration can opt for the Aadhaar authentication. The exceptions are persons exempted by the Central government under the CGST Act or those who must mandatorily undergo the Aadhaar authentication under section 25(6C) of the CGST Act. The revised rule will be effective for applications made on or after 21st August 2020.

From 1st April 2020 upto 20th August 2020, all the applicants submitting registration application under GST had to mandatorily undergo Aadhaar authentication for obtaining registration.

The applicants who opt for it must submit an Aadhaar Card along with the application for registration under GST. After this, they need 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 when opted or has not opted for it, the registration will be granted after a physical verification is done of the principal place of business. The officers can instead verify the documents on obtaining a permission from the officer not below the rank of Joint Commissioner and in writing.

In such cases, a notice in form GST REG-3 within 20 working days from the date of submitting the application. The date of submission of application is earlier of the below two:

  • Date of Aadhaar authentication
  • Date after counting 15 days from the submission of Part B of form GST REG-01, being the registration application.

The assessee must reply within 7 working days from the date of receipt of notice in form GST REG-4.

Earlier, the registration would 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.
