KO001 - South Korea tax invoice

Functionality has been added to support reporting of e-tax invoices to the South Korean tax authorities NTS. The e-tax invoice is mandatory, without that invoice it is not possible to deduct in-going VAT on supplier invoices in the VAT declaration. The supplier invoices are stopped for payment until reconciliation has been performed to verify that the VAT payable on the related E-tax tax invoice has been reported to NTS.
