GST — Goods and Services Tax
GST, or the Goods and Services Tax, is an indirect tax that came into effect in India on 1 July 2017. It is levied on the supply of goods and services, and it replaced the patchwork of indirect taxes that applied before it.

More on GST
GST was introduced mainly to bring uniformity to tax collection. Under the GST regime, tax is collected cumulatively at the final stage of producing goods or services. Following the GST 2.0 update there are four principal slabs — 0%, 5%, 18% and 40% — with different goods and services taxed at different rates, and some goods attracting no GST at all. The 12% and 28% rates from the earlier structure are included in this calculator for historical and transitional calculations.
There are four types of GST active in India
- CGSTCentral Goods and Services Tax
- Collected by the central government on the intra-state supply of goods and services, and governed by the CGST Act. It is charged alongside SGST, and the two rates are usually equal.
- SGSTState Goods and Services Tax
- Collected by the state government on the intra-state supply of goods and services, and governed by the SGST Act. It is charged alongside CGST, and the two rates are usually equal.
- IGSTIntegrated Goods and Services Tax
- Collected by the central government on inter-state supply as well as on imports. The centre collects IGST and then distributes it among the states concerned.
- UTGSTUnion Territory Goods and Services Tax
