How GST is calculated
When removing GST from an inclusive price: Base amount = Price ÷ (1 + rate ÷ 100).

- CGST: Central GST, 50% of total GST for intra-state transactions.
- SGST: State GST, 50% of total GST for intra-state transactions.
- IGST: Integrated GST, 100% of total GST for inter-state transactions.
- Key changes (Sept 2025): Essential items reduced to 5%, consumer electronics to 18%, luxury items increased to 40%. Insurance policies are now exempt (0%).
