About Indian GST

GST (Goods and Services Tax) is India's comprehensive indirect tax on the supply of goods and services. It replaced multiple cascading taxes and is applied at four slab rates: 5%, 12%, 18%, and 28%. For intra-state transactions, the GST is equally split into CGST (Central) and SGST (State). For inter-state transactions, IGST applies at the full rate.

Use GST Exclusive mode to add GST to a base price, or GST Inclusive to extract the base price and GST from a total amount that already includes tax.
