Common questions
What are the GST rates now?
Since 22 September 2025 most goods and services fall in two slabs, 5% and 18%, with 40% for luxury and sin goods such as tobacco, aerated drinks and large cars. Essentials can be 0%, gold and jewellery 3%, and rough diamonds 0.25%. The old 12% and 28% slabs were mostly folded into 5% and 18%. Check the current rate for your specific item before invoicing.
How do I remove GST from an inclusive price?
Divide the price by (1 + rate ÷ 100). For ₹1,180 including 18% GST, the price before tax is 1,180 ÷ 1.18 = ₹1,000 and the GST is ₹180. Choose "Remove GST" above to do this automatically.
When do I charge CGST and SGST, and when IGST?
For a sale within your own state, the GST is split equally into CGST (central) and SGST (state). For a sale to another state, the full amount is IGST.
