Do You Need GST Registration? Thresholds and Practical Triggers
Published: 10/9/2026

GST registration depends on turnover, what you sell, where you sell and how. The main thresholds, the cases where registration is required regardless of turnover and when voluntary registration makes sense.
Whether you need GST registration depends on three things: your turnover, what you supply and how you sell. In most states, businesses supplying only goods must register once aggregate turnover crosses ₹40 lakh, and service providers at ₹20 lakh, with lower limits in some special category states. But several situations require registration regardless of turnover.
The basic thresholds (most states)
| Supplier type | Registration required above (aggregate turnover) |
|---|
| Goods only (eligible businesses) | ₹40 lakh |
| Services, or goods and services | ₹20 lakh |
| Special category states | Lower limits apply; check your state |
Aggregate turnover is calculated on PAN basis across your businesses, including exempt supplies. Check the definition with your CA.
When registration is needed regardless of turnover
Common cases include:
- Inter-state supply of goods (with some relaxations for specific cases)
- Selling goods through e-commerce platforms (some relaxations have been introduced for small sellers and service providers; check current rules)
- Casual taxable persons (temporary business in another state, such as an exhibition stall)
- Businesses liable under reverse charge
- Certain other notified categories
When voluntary registration helps
Even below the threshold, registration can make sense if:
- Your customers are businesses that want input tax credit on your invoices
- You want to sell on marketplaces or to larger companies that insist on GSTINs
- You plan to grow past the threshold soon
The trade-off is compliance: regular returns and invoicing rules.
Composition scheme as a middle path
Small businesses can opt for the composition scheme within its turnover limits, paying tax at a fixed rate with simpler returns, but without collecting GST from customers or claiming input tax credit. See our composition vs regular guide.
