Step-by-Step GST Registration Process

Step 1: Go to the GST Portal

Visit https://www.gst.gov.in and click on ‘Register Now’ under the ‘Taxpayers’ section.

Step 2: Fill Part-A of the Form (GST REG-01)

You’ll need to provide:

• Legal name of the business (as per PAN)
• PAN number
• Mobile number and email (for OTP verification)
• State and district
• After submission, you’ll receive a Temporary Reference Number (TRN).

Step 3: Fill Part-B of the Form

Use the TRN to log in and complete Part B of the application. Upload the required documents and fill in:

• Business details
• Promoter/partner information

Step 4: Verification via Digital Signature (DSC) or EVC

Step 5: ARN Generation

Once verified, an Application Reference Number (ARN) will be generated. You can use this to track the application status.

Step 6: GSTIN Issued

If everything is in order, the GST officer will issue a GSTIN (GST Identification Number) within 7 working days. If clarification is required, the officer may raise a query via Form GST REG-03.
