Add GST to a base amount or remove GST from a GST-inclusive total. The calculator breaks down each result into CGST, SGST, and IGST based on whether your transaction is intra-state or inter-state. Choose Add GST when you have a price that does not yet include tax and want the final invoice total; choose Remove GST when you have a tax-inclusive price and want to extract the taxable value. Intra-state supplies split the GST equally into CGST and SGST; inter-state supplies levy the entire amount as IGST.
