What is GST?

Goods and Services Tax (GST) is a comprehensive indirect tax levied on the supply of goods and services across India. It replaced a complex web of central and state taxes like VAT, service tax, and excise duty.

GST is structured into four main tax slabs: 5%, 12%, 18%, and 28%. For intra-state transactions, the GST is split equally into CGST (Central) and SGST (State). For inter-state transactions, it applies as IGST.
