GST rates in India

RateApplies to (examples)

40%luxury and “sin” goods such as tobacco and some vehicles
0%fresh food, health and education services and other exempt supplies

In India the tax is called GST. To add 18%, multiply the net price by 1.18: ₹100.00 becomes ₹118.00. To remove it, divide the gross price by 1.18: ₹100.00 including GST is ₹84.75 net plus ₹15.25 GST. A common mistake is to take 18% off the gross price, which removes too much; the GST share of a gross price is 9/59, or 15.25%.

Since the GST rate rationalisation of 22 September 2025, most goods and services fall in two main slabs, 5% and 18%, with 40% for a short list of luxury and sin goods. Within a state GST is split equally into CGST and SGST (9% + 9% at 18%); across states it is charged as IGST.

Standard and reduced rates checked on 20 October 2026 against the GST Council and CBIC (cbic-gst.gov.in). Rates can change with each budget; the rate box is editable if a change takes effect.

FAQ

How is GST split into CGST and SGST?

For a sale within one state, half goes to the centre (CGST) and half to the state (SGST): 18% GST is 9% CGST + 9% SGST. Inter-state sales pay IGST at the full rate.

How do I remove GST from a price in India?

Divide the price including GST by 1.18. For example, ₹118.00 ÷ 1.18 = ₹100.00 net, so the GST is ₹18.00.
