How GST is Calculated
GST (Goods and Services Tax) is applied as a percentage of the taxable value. To add GST, multiply the base amount by the rate and add it on. To remove GST from a price that already includes it, divide by one plus the rate (e.g. ÷ 1.18 for 18%).
Within a single state, GST is split equally into CGST (central) and SGST (state). For inter-state supply, the same total is charged as a single IGST.
Which GST Rate Applies?
Services attract different GST rates depending on their category, with 18% being the most common rate for professional, IT, and creative services in India.
Goods vary across the 5%, 12%, 18%, and 28% slabs. The correct rate is tied to the HSN (goods) or SAC (services) code for your business.
