Korea Value-added Tax (VAT)
In Korea, Value-Added Tax (VAT) is imposed at a rate of 10% on the supply of goods and services. This tax covers various goods and services, including those for exportation, certain eligible services rendered to non-residents, and professional services such as legal, accounting, and management consulting. Some goods are zero-rated, such as basic life necessities and services, and international transportation services. VAT also applies to non-resident companies providing electronic services to consumers in Korea. The requirement for electronic VAT invoicing is strictly enforced, and failure to comply with electronic VAT requirements may lead to significant penalties. Foreign companies providing services through electronic platforms must register for VAT and adhere to filing requirements. This includes maintaining transaction records for five years, particularly in digital marketplaces and intermediary services.

This tax serves as a local tax, managed by local governments, ensuring that industrial and real estate developments contribute to the local infrastructure and economy.
