To add GST to a base price: GST Amount = Base Price × GST Rate ÷ 100. Total = Base Price + GST Amount. Example: Base price ₹10,000 at 18% GST → GST = ₹1,800 → Total = ₹11,800. For intrastate: CGST = ₹900 + SGST = ₹900. For interstate: IGST = ₹1,800.
To extract the base price from an amount that already includes GST (MRP or inclusive price): Base = Total ÷ (1 + GST Rate ÷ 100) Example: MRP ₹11,800 with 18% GST → Base = 11,800 ÷ 1.18 = ₹10,000. GST included = ₹1,800.
CGST (Central GST) and SGST (State GST) apply to intrastate transactions — when the seller and buyer are in the same state. Each is half the total GST rate. IGST (Integrated GST) applies to interstate transactions — seller and buyer in different states. It equals the full GST rate and is collected by the central government.
Most services in India are taxed at 18% GST. This includes IT/software services, consulting, restaurants (non-AC), financial services, and most professional services. Exempt: healthcare, education, essential banking. 5%: passenger transport, small restaurant services. 28%: luxury hospitality, amusement parks, gambling.
