Goods and Services Tax (GST) is charged on most goods and services sold in India. Businesses add GST to their selling price and pass it on to the government, after claiming credit for GST paid on their own purchases.
Since 22 September 2025, most items fall under two main rates — 5% and 18% — with a 40% rate for luxury and ‘sin’ goods, some items exempt (0%) and special rates for a few such as gold (3%). Always confirm the rate for your specific product or service code (HSN/SAC).
GST to add = Price × Rate ÷ 100 · Price without GST = Total × 100 ÷ (100 + Rate)
Since 22 September 2025 the main rates are 5% and 18%, with 40% for luxury and sin goods. Some goods are exempt and a few have special rates, such as 3% on gold.
Divide the total by (100 + GST rate) and multiply by 100. For example, ₹1,180 including 18% GST has a base price of ₹1,000.
For sales within a state, GST is split equally into Central GST and State GST. For sales between states, it is charged as Integrated GST.
Generally businesses whose turnover exceeds the threshold (₹40 lakh for most goods suppliers and ₹20 lakh for services, lower in some states), and certain others such as inter-state and e-commerce sellers. See our India compliance guide and confirm with a professional.
