GST (Goods and Services Tax) in India is calculated on the taxable value of goods or services. For intra-state supplies, GST is split equally between CGST (Central) and SGST (State). For inter-state supplies, IGST (Integrated) is charged at the full rate.
Post GST 2.0 (September 2025), the primary slabs are 5% for essentials, 18% for standard goods/services, and 40% for luxury/sin goods. Special rates of 3% for precious metals and 0.25% for rough diamonds continue.
