GST Information Required on E-Invoices
Peppol e-Invoicing and GST in Australia requires that every PINT A-NZ invoice includes the supplier’s GST registration status and ABN, GST treatment codes for each line item, total GST amount, and GST-inclusive total. The GST Compliance Australia field requirements for Peppol invoices are validated automatically by the Access Point before transmission, preventing invoices with missing or incorrectly coded GST fields from entering the network. GST treatment codes in the PINT A-NZ format classify each line item as standard-rated, zero-rated, GST-free, or outside the scope of GST, providing clear and unambiguous tax classification for every invoice item.
