Who Should Register for GST? Complete Eligibility Explained
Goods and Services Tax (GST) is one of the most significant tax reforms in India. While it has simplified indirect taxation by combining multiple taxes into one, understanding who needs to register for GST is still confusing for many business owners, startups, and professionals.
If you're running a business, providing services, or selling products, it’s important to know whether GST registration is mandatory for you, or whether you can benefit by registering voluntarily. This guide explains the complete eligibility for GST registration in simple terms.
Who is Required to Register for GST?
As per the GST Act, the following categories of taxpayers must register for GST:
1. Businesses Exceeding Turnover Threshold
If your aggregate turnover exceeds:
• ₹40 lakh for supply of goods (₹20 lakh in special category states)
• ₹20 lakh for supply of services (₹10 lakh in special category states)
• Then GST registration becomes mandatory.
Note: Special category states include Manipur, Mizoram, Nagaland, and Tripura.
2. Interstate Suppliers
If you supply goods or services from one state to another, you are required to register for GST regardless of your turnover.
Example: If you're a small manufacturer in Rajasthan selling products to customers in Delhi, GST registration is mandatory even if your turnover is below ₹40 lakh.
3. E-commerce Sellers
Businesses selling through online marketplaces like Amazon, Flipkart, or their own websites must obtain GST registration irrespective of turnover.
This includes:
• Product sellers
• Dropshippers
• Service providers operating through digital platforms
4. Casual Taxable Persons
If you occasionally supply goods or services in a different state without a fixed place of business, you must register as a casual taxable person.
Example: Setting up a temporary exhibition stall in another state.
5. Non-resident Taxable Persons
Non-residents who occasionally supply goods or services in India are required to register under GST.
6. Agents and Input Service Distributors
Any person acting as an agent supplying goods or services on behalf of another registered person must get registered.
Input Service Distributors (ISD) who distribute input tax credit to branches also need to register.
7. Reverse Charge Mechanism (RCM) Liability
If you're liable to pay tax under the reverse charge mechanism, registration is mandatory.
This applies to businesses that:
• Procure services from unregistered vendors
• Fall under notified categories of RCM applicability
8. Voluntary Registration
Even if you are not required to register under the above criteria, you can still opt for voluntary registration to avail benefits like:
• Input tax credit
• Increased credibility with clients
• Participation in e-commerce and government tenders
