CGST (Central GST) and SGST (State GST) are charged on sales within the same state (intra-state). Each is half the applicable GST rate. For example, on an 18% GST purchase within your state, you pay 9% CGST + 9% SGST.
IGST (Integrated GST) is charged on sales between two different states (inter-state). It equals the full GST rate โ so the same 18% item sold across states attracts 18% IGST.
To add GST (calculate tax on a base price): GST Amount = Base Price ร GST Rate รท 100. Total = Base Price + GST Amount.
To remove GST (find base price from a GST-inclusive price): Base Price = Total ร 100 รท (100 + GST Rate). GST Amount = Total โ Base Amount.
Search by product name and the right slab is filled in for you, drawn from a curated list of 125 everyday goods and services โ no separate lookup, no guessing which slab a branded item falls into.
