The box exists because some supplies are inter-State by law even when the supplier and place of supply are in the same State. Cases:
• Supplies to an SEZ developer or unit in your own State: inter-State under Sec 7(5)(b) IGST. These are usually reported in SEZ tables 6B/9.
• Supply to a foreign tourist: Sec 15 IGST refund scheme.
• Supplies by an Indian supplier where Sec 7(5)(c) residuary applies.
• Supplies under reverse charge where the recipient pays IGST.
• Since the 2020 IGST amendment: supplies to a Duty Free Shop / Customs bonded warehouse.
For a normal domestic intra-State sale to a registered buyer, leave it unticked and charge CGST + SGST. Charging IGST wrongly does not count as payment of the right tax. The supplier must pay CGST + SGST and claim a refund of the IGST under Sec 77 CGST / Sec 19 IGST.
