Add vs remove GST
"Add GST" takes a pre-tax (exclusive) price and adds the tax. "Remove GST" takes a final (inclusive) price and works backwards to find the base and the tax within it — useful for reverse-calculating from an MRP.
CGST + SGST
For intra-state sales, GST splits equally into Central GST and State GST. For inter-state sales it becomes a single IGST at the same total rate.
