Rates after 22 September 2025
Most goods and services are now at 5% or 18%, luxury and sin goods at 40%, gold and silver at 3%. The old 12% and 28% slabs were folded into these; a few items such as tobacco keep their earlier rate with cess for now. Check the rate of your HSN or SAC code before you invoice.How it is worked out
- Adding GST: GST = amount x rate; the price with GST = amount + GST.
- Removing GST from an inclusive price: price before GST = amount / (1 + rate); GST = amount - that price.
- Within the state the tax is split equally between CGST and SGST; a sale to another state carries IGST at the full rate.
- Rates offered are those in force since 22 September 2025 (5%, 18%, 40%, 3% and 0.25%); any other rate can be typed.
