What this means for you

Corporate taxpayers have been required to issue electronic tax invoices since 2011. The individual-business threshold expanded to KRW 80 million of prior-period taxable and exempt supply value from July 2024; the official source does not support inventing a day within 2011 for corporations.

What FreeBillGen can verify

For eligible saved invoices, FreeBillGen can prepare generic OASIS UBL and UN/CEFACT CII mappings and run its named internal checks. These mappings are not EN 16931, Factur-X, Peppol, national-CIUS or clearance-platform validation. FreeBillGen does not transmit them through a provider network.
