Mandate Overview
The mandate
South Korea's National Tax Service (NTS) operates the e-Tax Invoice (전자세금계산서) system, one of the world's earliest e-invoicing mandates. Mandatory for all corporate taxpayers since January 1, 2011 and progressively extended to individual entrepreneurs (sole proprietors), the regime requires every VAT-registered business to issue tax invoices electronically and transmit them to the NTS Hometax platform within one day of issuance. Late or missing transmissions trigger automatic penalties (typically 0.5% of the supply value). The 2025 turnover threshold for individual entrepreneurs has been progressively reduced — currently 80 million KRW annual supply value brings individual entrepreneurs into mandatory scope, down from earlier higher thresholds.
