How to Register for GST Online in India (Step-by-Step, 2026)

Registering for GST is mandatory for many businesses and freelancers in India. This step-by-step guide walks you through the entire online registration process on the official portal.

Who Needs to Register for GST?

For most service providers (including freelancers), GST registration is mandatory if your aggregate turnover exceeds ₹20 Lakhs in a financial year (or ₹10 Lakhs in Special Category States). For businesses exclusively supplying goods, the limit is ₹40 Lakhs.

Note: If you are an Indian freelancer with international clients, you must register for GST and file a LUT to export services without paying IGST, even if your turnover is below ₹20 Lakh.

Step-by-Step Process to Register Online

Follow these steps on the official GST Portal:

1. Generate a TRN (Temporary Reference Number)

• Go to Services > Registration > New Registration.
• Fill out Part A using your Legal Name, PAN, Email, and Mobile Number.
• Verify via OTP to receive your TRN.

2. Complete Part B of the Application

• Log in using the TRN.
• You will need to fill in comprehensive details about your business, proprietors/partners, and principal place of business.

3. Upload the Required Documents

Have the following ready in digital format:

• PAN Card
• Aadhaar Card
• Proof of Business Address (Rent agreement, electricity bill)
• Bank Account Proof (Cancelled cheque or passbook extract)

4. Aadhaar Authentication

Opting for Aadhaar authentication significantly speeds up the approval process. You will receive an authentication link on your registered email and mobile number.

5. Receive your GSTIN

Once submitted, an Application Reference Number (ARN) is generated. You can use this to track your status. Once approved by the tax officer, your 15-digit GSTIN and certificate will be issued.

Next Steps After Registration

Once you receive your GSTIN, you must begin charging GST (if applicable) and filing regular returns. You can use our Free GST Invoice Generator to create professional, compliant invoices for your clients. To calculate the exact tax breakdown, use our GST Calculator.
