GST – Goods and Services Tax in India
Goods and Services Tax (GST) is an indirect tax that has replaced multiple central and state taxes in India such as VAT, excise duty, and service tax. GST is charged on the supply of most goods and services and is collected at every stage in the value chain, from manufacturer to end consumer. India's Goods and Services Tax (GST) system, as of 22 September 2025, primarily operates on a simplified structure with two main slabs of 5% and 18%, with a special 0% slab for essential items and a higher 40% rate for certain luxury and sin goods. Use this goods and service tax calculator (GST cal) to quickly compute base price, GST portion and total payable.
