How it works
How GST inclusive and exclusive work
Same rate, two directions. Exclusive adds GST on taxable value. Inclusive backs GST out of an invoice total.
02
Inclusive — remove GST
Taxable = total ÷ (1 + rate) · GST = total − taxable
₹1,180 at 18% → taxable ₹1,000 → GST ₹180
Intra-state
CGST + SGST
GST splits equally. Use this when supplier and place of supply are in the same state.
Inter-state
IGST
Full rate as IGST. Use this for supplies across states, including most e-commerce flows.
