Prepare for South Korea’s expanding e-Tax Invoice requirements
South Korea has required electronic tax invoices for corporate taxpayers since 2011. Over the past five years, the biggest change has been the continued reduction of turnover thresholds, most recently expanding the mandate to businesses with annual revenue exceeding KRW 100 million from 1 July 2023, with further expansion to smaller businesses continuing thereafter.
What will change in South Korea
South Korea operates a real-time e‑Tax Invoice model managed by the National Tax Service (NTS).
- Mandatory electronic tax invoices apply to all corporate taxpayers and an expanding group of individual businesses based on annual turnover thresholds
- Invoices must be generated electronically in XML format, digitally signed, and transmitted to the National Tax Service (NTS)
- The latest major update lowered the threshold to KRW 100 million from July 2023, significantly expanding the number of businesses required to comply
South Korea continues to strengthen digital tax reporting through broader taxpayer coverage, tighter validation requirements, and ongoing automation of tax compliance processes.
