GST Rate Slabs in India (2026)
India uses a multi-slab GST structure. The rate applied depends on the HSN/SAC classification of the product or service — not on the seller's preference. Common slabs:
| Rate | Examples |
|---|---|
| 0% | Fresh milk, bread, educational services, healthcare |
| 5% | Packaged food items, transport services, coal |
| 12% | Processed food, business-class air travel |
| 18% | Most services, IT hardware, telecom, restaurants (non-AC) |
| 28% | Luxury cars, aerated drinks, tobacco products |
GST exclusive → inclusive: A laptop priced at ₹50,000 (ex-GST) at 18% GST → GST = ₹9,000 → Customer pays ₹59,000.
GST inclusive → exclusive: An invoice shows ₹11,800 (GST inclusive) at 18% → Base = 11,800 ÷ 1.18 = ₹10,000 → GST component = ₹1,800. This is the calculation freelancers use when a client quote is "inclusive of all taxes."
CGST + SGST vs IGST: For intra-state sales, GST splits equally into CGST and SGST (9% + 9% = 18%). For inter-state sales, IGST at the full 18% applies. Our calculator shows total GST; your invoice must split by supply type.
