Frequently asked questions
What are the current GST rates in India?
Since GST 2.0 came into effect on 22 September 2025, the main slabs are 5% and 18%, with a 40% rate for luxury and sin goods, plus 0% for exempt items and a special 3% rate for gold and silver. Always check the rate for your HSN/SAC code.
How do I remove GST from a GST-inclusive price?
Choose “Remove GST”, enter the total and the rate. The tool divides by (1 + rate ÷ 100) to give the base price and the GST amount.
When is CGST + SGST used instead of IGST?
For sales within the same state GST is split equally into CGST and SGST. For sales to another state, the full amount is charged as IGST.
