Aadhaar Authentication On GST Portal

On 6 January 2021, the functionality for Aadhaar Authentication and e-KYC was deployed on the GST Common Portal. With this feature, the existing GST registered Taxpayers can verify their identity using Aadhaar authentication through the GST portal itself. In case the Aadhaar (of the signatories) is not available, the Taxpayers have an option to complete GST e kyc verification. In this article, you'll know about E KYC portal for GST registration, how to do E KYC in GST portal and how to update KYC in GST portal.


What Is Aadhaar Authentication/e-KYC?

To verify the identity of Taxpayers registering on the GST portal, the Government had enabled Aadhaar authentication for newly registered Taxpayers in late 2020. Now, this feature has been extended to the existing registered Taxpayers as well. Through this mechanism, the Government targets to verify the identity of Taxpayers digitally, without having to verify them physically. This will, in turn, save time and effort for both, the Taxpayer and the Government. With Aadhaar Authentication for GST, the Taxpayer can authenticate the ‘Primary Authorised Signatory’, and one other person who is the Proprietor/Partner/Director/Managing Partner/ Karta of the GST registered entity.

Note: To initiate this process, the signatories should have a valid Aadhaar number.

If the signatories mentioned above (of the GST registered entity) do not have an Aadhaar number, then, the Taxpayer can use their other eKYC documents to complete the e-kyc portal aadhar authentication. The admissible documents here are:

  • Aadhaar enrolment number
  • Passport
  • Voter ID card
  • KYC form
  • Identifying certificate issued by a Competent Authority
  • Other documents that might be specified by the GSTN from time to time.


How To Do Aadhaar Authentication in GST Portal?

  • When a Taxpayer logs in to his/her GST account on the GST portal, he/she will see a pop-up asking ‘Would you like to authenticate Aadhaar of the Partner/Promotor and Primary Authorized Signatory’. Here, the Taxpayer can select ‘Yes, navigate to My Profile’ or ‘Remind me later’.

  • The Taxpayers can choose to ignore the pop-up by clicking on ‘REMIND ME LATER’. This will close the pop-up message window.
  • If the Taxpayer clicks on ‘Yes, navigate to My Profile’, he/she will be navigated to the ‘My Profile’ page. Here, a new tab called ‘Aadhaar Authentication status’ has been enabled. By clicking on this tab, the Taxpayer can ‘Send Aadhaar Authentication link’.

  • The Taxpayer can select only one name here.
  • If the same person is the Primary Authorised Signatory and the Partner/Promoter as well, Aadhaar authentication of that one person alone is sufficient. The check box against the name would be auto-selected, and the Taxpayer is required to click the ‘SEND VERIFICATION LINK’ directly.

Once this is done, a pop-up message window is displayed stating that the link has been shared to the registered Email address and mobile number. Click on ‘OK’ to close the window. Aadhaar Authentication On GST Portal
