Understanding South Korea’s VAT for SaaS

South Korea implemented a Value-Added Tax (VAT) system in 1977 to enhance tax compliance and modernize its tax administration. The current standard VAT rate for SaaS and other digital services is set at 10%. While there is no reduced rate or specific exemptions for digital goods or services, businesses are required to maintain detailed records for a minimum of five years. These records include sales and purchase records such as tax invoices, credit notes, import documentation, and accounting records. Additionally, businesses with an annual revenue exceeding KRW 100 million (approximately USD 75,000) are obligated to comply with e-invoicing requirements.
