Frequently asked questions
How do I remove GST from a price?
Divide the price by (100 + GST rate) and multiply by 100. For ₹1,180 at 18%: 1,180 × 100 ÷ 118 = ₹1,000 before GST, and ₹180 is GST.
When is CGST + SGST charged and when IGST?
CGST and SGST are charged when the supplier and the place of supply are in the same state. IGST is charged when they are in different states, and on imports and exports.
What are the GST rates now?
Since 22 September 2025 most goods and services are taxed at 5% or 18%, with 40% on a few luxury and sin goods and special rates such as 0.25% and 3% for some items. A few items still have older rates, so check the rate for your HSN code before billing.
