GST Registration in India: 2025 (Process, Documents, Benefits & Common Issues)
GST Registration is one of the most essential compliance requirements for businesses operating in India. Whether you are a small proprietor, a service provider, a manufacturer, or an online seller, obtaining a GST number (GSTIN) is crucial for conducting business legally and gaining customer trust.
This guide explains the entire GST registration process, the documents you need, key benefits, common mistakes to avoid, and how you can download your GST certificate once approved.
What Is GST Registration?
GST Registration is the process of enrolling a business under the Goods and Services Tax (GST) system in India. Once approved, the government issues a unique GSTIN (Goods and Services Tax Identification Number), which acts as your tax identity for all GST-related activities.
GST Registration is mandatory if your annual turnover crosses the prescribed threshold or if you fall under specific categories such as e-commerce sellers, inter-state suppliers, or businesses operating online.
Who Needs GST Registration in 2025?
A business must register for GST if:
Turnover Threshold
- Service providers: Above ₹20 lakh
- Goods suppliers: Above ₹40 lakh
- Special category states: Above ₹10 lakh
Mandatory Registration Categories
- Inter-state suppliers
- E-commerce sellers (Amazon, Flipkart, Meesho, JioMart)
- Online service providers
- Businesses dealing under Reverse Charge Mechanism (RCM)
- Importers and exporters

If you fall under any of these categories, GST registration is compulsory regardless of turnover.
