Since 22 September 2025 (GST 2.0), most goods and services fall under 5% or 18%, with 40% for luxury and sin goods. Special rates of 3% (gold, silver) and 0.25% (rough diamonds) still apply, and some essentials are exempt.
Base price = inclusive price × 100 ÷ (100 + GST rate). For 18% GST, ₹1,180 inclusive means a ₹1,000 base price and ₹180 GST.
Sales within the same state are split equally into CGST and SGST. Sales between states (and imports) attract IGST at the full rate.
