GST Registration in India: Complete Step-by-Step Guide
The Goods and Services Tax is the single biggest indirect tax reform in India, and registration under it is the first compliance step for most growing businesses. Whether you are a trader, manufacturer, service provider, or e-commerce seller, this guide explains GST registration in India step by step — who needs it, the threshold limits, the documents, and the online process.
What Is GST Registration?
GST registration is the process of obtaining a unique 15-digit GST Identification Number (GSTIN) from the government. Once registered, a business can legally collect GST, claim input tax credit, and file returns. Registration is done online on the GST portal.
Who Needs to Register for GST?
- Businesses with aggregate turnover above the threshold limit.
- Persons making inter-state supplies of goods.
- E-commerce operators and sellers on e-commerce platforms.
- Casual taxable persons and non-resident taxable persons.
- Those liable under reverse charge.
- Input service distributors and agents.
GST Threshold Limits
Registration becomes mandatory once aggregate turnover crosses the threshold:
| Category | Threshold (Goods) | Threshold (Services) |
|---|---|---|
| Normal states | ₹40 lakh | ₹20 lakh |
| Special category states | ₹20 lakh | ₹10 lakh |
Many businesses register voluntarily before crossing the limit to claim input tax credit and appear credible to customers.
Documents Required for GST Registration
- PAN of the business/applicant.
- Aadhaar of the proprietor/partners/directors.
- Proof of business registration or incorporation certificate.
- Identity and address proof of promoters/directors.
- Proof of principal place of business (utility bill, rent agreement, NOC).
- Bank account details (cancelled cheque or statement).
- Digital Signature Certificate (for companies and LLPs).
Step-by-Step Registration Process
1. Visit the GST Portal
Go to the GST portal and start a new registration under “Services > Registration > New Registration”.
2. Fill Part A
Enter PAN, mobile, and email. Verify through OTP to generate a Temporary Reference Number (TRN).
3. Fill Part B
Using the TRN, complete business details, promoters, place of business, goods/services (HSN/SAC), and bank details, and upload documents.
4. Aadhaar Authentication
Complete Aadhaar authentication to speed up approval.
5. ARN and GSTIN
On submission, an Application Reference Number (ARN) is generated. Once approved, the GSTIN and registration certificate are issued.
Timeline
With Aadhaar authentication and complete documents, registration is typically granted within 3 to 7 working days. Cases flagged for physical verification take longer.
Frequently Asked Questions
Is GST registration mandatory for all businesses?
No — only above the threshold or in specified cases (inter-state supply, e-commerce, etc.). Others may register voluntarily.
Can I register voluntarily?
Yes. Voluntary registration lets you claim input tax credit and supply across states.
How long does registration take?
Usually 3 to 7 working days with Aadhaar authentication and complete documents.
Is a separate registration needed for each state?
Yes — GST is state-specific, so a presence in multiple states needs registration in each.
