How GST Works
India uses a dual GST structure: CGST (Central GST) and SGST (State GST) for intra-state transactions, and IGST (Integrated GST) for inter-state supplies.
For any transaction within a state at 18% GST: 9% goes to the Centre (CGST) and 9% to the State (SGST).
GST slabs in India: 0%, 0.25%, 3%, 5%, 12%, 18%, 28%. A cess is levied on certain luxury and sin goods above 28%.
