What is exempt, nil-rated and zero-rated supplies?
These three look similar but are treated very differently for input tax credit.
GST in India is a destination-based tax split into CGST and SGST for sales within a state and IGST for inter-state sales. Following the rate overhaul effective 22 September 2025, most goods and services sit in a simplified two-slab structure (5% and 18%), with a higher 40% rate reserved for a short list of luxury and "sin" items, and essentials kept exempt.
Why it matters for your business
Understanding exempt, nil-rated and zero-rated supplies keeps your invoices compliant, protects your input tax credit, and avoids notices from the department. Small mistakes here are what trigger mismatches and penalties later.
- Exempt: no GST charged, and no input tax credit on related inputs.
- Nil-rated: taxed at 0% by the rate schedule.
- Zero-rated: exports and SEZ supplies — 0% tax but you keep the input tax credit and can claim a refund.
A quick example
An exporter ships zero-rated goods, charges no GST, yet still claims a refund of the GST paid on inputs — unlike an exempt-goods seller, who cannot.

Frequently asked questions
What exactly is exempt, nil-rated and zero-rated supplies in GST?
These three look similar but are treated very differently for input tax credit.
Is this the same across all Indian states?
GST is a national law, so the core rules are the same across India, but the state (SGST) half of the tax and your jurisdictional office depend on the place of supply.
Does HelloBooks handle this automatically?
Yes — HelloBooks applies the correct treatment on every invoice and carries it through to your GSTR-1 and GSTR-3B so you do not have to calculate it by hand.
