Exclusive (add): GST is added on top of the amount. Inclusive (remove): the amount already contains GST and is broken back out.
Intra-State supply attracts CGST + SGST/UTGST (rate split equally); Inter-State supply attracts IGST (full rate) — s. 9 CGST Act / s. 5 IGST Act.
Standard slabs are 0%, 5%, 12%, 18% and 28%; special rates include 0.25% (rough diamonds), 1.5% and 3% (gold).
