Threshold ₹20,00,000
What this means
- The aggregate-turnover threshold for services is ₹20,00,000.
- Aggregate turnover means ALL your supplies across India on the same PAN — not just the ones from this business, and not just the taxable ones.
- Some situations require registration whatever your turnover: making inter-state supplies of goods, selling through an e-commerce operator, or being liable under reverse charge. Exporting services is a zero-rated supply but usually still needs registration to claim the benefit.
- Registering voluntarily lets you claim input tax credit, but commits you to monthly or quarterly returns for as long as you stay registered.
Questions people actually ask
- When do I have to register for GST?
- Aggregate turnover means everything on your PAN, not just this business. The threshold is ₹20 lakh for services and ₹40 lakh for goods — but some situations require registration whatever your turnover, such as selling through an e-commerce operator.
