Is the state code in a GSTIN the same as the place of supply?
No. The state code shows where the supplier or buyer is registered. The place of supply is worked out under the IGST Act rules for goods or services. Comparing the supplier's location with the place of supply decides whether CGST + SGST or IGST applies.
What happens if an invoice uses the wrong tax because of the state code?
If CGST + SGST is charged where IGST was due (or the other way round), the supplier generally has to pay the correct tax and claim a refund of the amount paid under the wrong head. The buyer's input tax credit can also be held up until the invoice is corrected, so check the buyer's GSTIN before invoicing.
