The Goods and Services Tax (GST) is India’s main indirect tax on the supply of goods and services. Businesses above a certain turnover must register under GST and get a GST Identification Number (GSTIN). Here is a guide to who needs to register and how.
Turnover limits
Registration is needed when aggregate annual turnover crosses:
- Rs 40 lakh for businesses that only supply goods, in most states.
- Rs 20 lakh for service providers.
- Lower limits apply in some special category states, such as Rs 20 lakh for goods and Rs 10 lakh for services in certain north eastern and hill states.
Aggregate turnover includes all taxable, exempt and export supplies across India under the same PAN.

When registration is compulsory
Some businesses must register even if turnover is below the limit:
- Those making inter state supplies of goods.
- Sellers on e-commerce platforms, with some exceptions for service providers.
- Casual taxable persons and non resident taxable persons.
- Those liable to pay tax under reverse charge.
- Input service distributors and agents supplying on behalf of others.
Composition scheme
Small businesses with turnover up to Rs 1.5 crore (lower in some states) can opt for the composition scheme. They pay tax at a low fixed rate on turnover and file simpler returns, but cannot collect GST from customers or claim input tax credit.
