Common questions
What is the difference between GST-inclusive and GST-exclusive?
GST-exclusive means the listed price does NOT include GST — the tax is added on top. GST-inclusive means the listed price already includes GST, and you need to extract the base price and tax amount from the total.
What are CGST, SGST, and IGST?
CGST (Central GST) and SGST (State GST) are charged on intra-state transactions (within the same state), each being half the total GST rate. IGST (Integrated GST) is charged on inter-state transactions at the full GST rate.
