CGST + SGST or IGST?

Selling within Andhra Pradesh — seller and place of supply both under code 37 — splits the GST equally into CGST and SGST: an 18% supply becomes 9% + 9%. Selling from Andhra Pradesh to any other code (or buying in from one) makes it an interstate supply with a single IGST line at the full rate. Your customer's GSTIN prefix is the quickest way to know which applies.
