Frequently asked questions
How do I remove GST from a price?
Choose "already includes GST". The base price is the amount divided by 1 plus the rate, for example amount / 1.18 at 18%.
What is CGST and SGST?
For sales inside one state, GST is split equally between the Centre (CGST) and the state (SGST). For sales between states it is charged as IGST at the full rate.
