How it works

Add GST

Enter the base (pre-tax) amount. GST is calculated on top to give you the total payable.

Remove GST

Enter the GST-inclusive total. The base amount and tax are back-calculated automatically.

CGST/SGST vs IGST

Intra-state splits GST equally into CGST + SGST. Inter-state applies the full rate as IGST.
