GST rates in India (2026)
The standard rate of 18% applies to most goods and services. Reduced rates (5%) apply only to specific goods and services defined by law. Locally, the tax is called Goods and Services Tax (GST). Registration / small-business threshold: ₹40 lakh (goods) / ₹20 lakh (services) annual turnover.
Good to know
- Since 22 September 2025 GST has two main slabs, 5% and 18%, with a 40% rate for luxury and “sin” goods; some goods remain exempt or at special rates.
How it’s calculated
VAT is charged as a percentage of the net (pre-tax) price. To add it, multiply the net amount by the rate; to find the net amount inside a tax-inclusive price, divide the gross amount by 1 plus the rate.
A common mistake is to remove VAT by subtracting the rate from the gross price (e.g. 119 − 19% = 96.39). That is wrong — the correct net amount is 119 ÷ 1.19 = 100.
Gross = Net × (1 + rate ÷ 100)VAT = Net × rate ÷ 100Net = Gross ÷ (1 + rate ÷ 100)
