GST registration is not optional if your business crosses the prescribed turnover threshold — and getting it wrong, whether by registering late or not registering at all, attracts penalties that can run into significant amounts. Whether you are a freelancer, a trader, a manufacturer, or a service provider, this guide tells you exactly who must register, what documents you need, and how to complete the process on the GST portal without confusion.
Who Is Required to Register for GST?
The most common trigger for GST registration is crossing the annual aggregate turnover threshold. For most states, this threshold is ₹40 lakhs for goods suppliers and ₹20 lakhs for service providers. However, for businesses operating in special category states (like the North-Eastern states, Himachal Pradesh, and Uttarakhand), the threshold is lower — ₹20 lakhs for goods and ₹10 lakhs for services.
Beyond the turnover threshold, certain categories of businesses must register for GST regardless of their turnover — this is called mandatory GST registration. These include:
- Businesses making inter-state taxable supplies (selling goods or services across state borders)
- E-commerce operators and sellers on platforms like Amazon, Flipkart, Meesho, or Myntra
- Non-resident taxable persons making taxable supplies in India
- Persons required to deduct or collect TDS/TCS under GST
- Input service distributors and agents supplying on behalf of a principal
- Businesses previously registered under VAT, Service Tax, or Excise Duty
