Goods and Services Tax (GST) registration is the process by which a business or individual becomes registered under the Goods and Services Tax Act, 2017. Once registered, the entity is recognized as a supplier of goods or services and is legally required to collect and pay GST to the government.
GST registration is governed by Chapter VI of the CGST Act, 2017 and the CGST Rules, 2017 (Rules 8–26).
GST registration is mandatory for:
Businesses with an aggregate annual turnover exceeding:
₹40 lakhs (for goods)
₹20 lakhs (for services)
₹10 lakhs (for Special Category States)
Persons making inter-state taxable supplies
Casual taxable persons and non-resident taxable persons
Persons required to pay tax under reverse charge
Agents of a supplier
Input Service Distributors (ISD)
E-commerce operators and suppliers via e-commerce portals
Businesses with turnover below the threshold limit may also opt for voluntary registration to avail input tax credit and enhance credibility.
