GST Registration (REG-01): Auto-Fill from Existing GSTIN, Geo-Based Jurisdiction and Field-Level Help

GSTN has rolled out three GST registration new features in FORM GST REG-01, live on the portal from 1 September 2026. They are aimed at businesses that already hold a GSTIN and are opening in a new location, and at first-time applicants who often get stuck choosing the right jurisdiction or understanding what a field asks for.

GST registration new features at a glance

1. Auto-fill from an existing GSTIN

If your business already has an active GSTIN, you can reuse its details when applying for another registration under the same PAN, in the same State or a different one.

1. 1

   Choose auto-population

   In Part-B of FORM GST REG-01, select "Yes – Auto-Populate Details".

2. 2

   Get consent by OTP

   The Primary Authorised Signatory (PAS) of the existing GSTIN gives consent through an OTP.

3. 3

   Review and edit

   Eligible details are filled in automatically. Review them, change anything that differs for the new registration, then save and continue.

4. 4

   Promoters are informed

   Relevant promoters/partners receive an SMS and e-mail after successful verification.

2. Jurisdiction suggested from your location

When you enter your principal place of business, the portal uses its latitude and longitude to recommend the State and Centre jurisdiction. The suggestion is editable: you can keep it or choose another jurisdiction from the drop-down. Choosing the wrong jurisdiction is a common cause of delays, so this should mean fewer queries during processing.

3. Help inside the form

REG-01 now shows information messages at relevant fields and tooltips you can hover over. This explains what each field needs as you fill it in, so you do not have to look up separate instructions.

Tips before you apply

• Keep the Primary Authorised Signatory of the existing GSTIN available, because the OTP goes to them.
• Review every auto-filled field: the business activity, goods and services, bank details and signatories may differ for the new location.
• Enter the full address of the new principal place of business accurately so the suggested jurisdiction is correct.
• Upload clear proof of the new place of business, such as a rent agreement with electricity bill, or an ownership document.

What has not changed

• Each registration is still for one State/UT and gives a separate GSTIN.
• You still need proof of place of business and Aadhaar authentication for the new application.
• The jurisdiction suggestion is only a recommendation: check it before submitting.

Applying in several States at once? The new Multi-State Registration facility lets you enter common details once under one Master TRN. For the basics, see GST registration in India.
