Goods and Services Tax (GST) is India's unified indirect tax, charged on the supply of most goods and services. It replaced a patchwork of state and central taxes with a single rate structure, currently set at 3%, 5%, 12%, 18% or 28% depending on the item.
For sales within the same state, GST is split evenly into CGST (collected by the central government) and SGST (collected by the state government). For sales across state lines, the same total is instead charged as IGST. This tool assumes an intra-state sale and shows the CGST/SGST split accordingly.
