Summary
Lee Hyoung-il, nominee for South Korea's Ministry of Finance and Economy, publicly declared his support for implementing the nation's long-delayed cryptocurrency tax effective January 1, 2027, signaling the government's commitment to proceed despite sustained opposition from the crypto industry and political figures. Speaking on September 13, 2026, Lee defended the classification of crypto income as miscellaneous income as "appropriate" and emphasized the tax's necessity for fairness in the broader tax system.
The tax framework establishes a 20% flat rate on cryptocurrency profits (22% including local income tax) applied to gains from transferring or lending digital assets, with an annual basic deduction of 2.5 million won. Transactions subject to taxation will commence in 2027, with taxpayers required to file and settle payment obligations in May 2028. Lee indicated that the National Tax Service would finalize detailed implementation rules via public notice before year-end 2026, providing market participants several months' notice before the January 2027 launch.
The repeated postponement of this policy underscores persistent implementation challenges. Originally scheduled for 2022, the tax has been pushed back three times due to inadequate tax collection infrastructure, cryptocurrency market volatility, and incomplete regulatory safeguards for retail investors. The current January 2027 target represents the fourth attempted implementation date. DAXA, South Korea's primary crypto industry association, contends that exchanges still lack standardized digital networks for data sharing with regulatory authorities and require substantially more lead time for system testing and operational readiness. Opposition lawmakers have mounted formal resistance: Rep. Song Eon-seog proposed abolishing the crypto tax clauses entirely, while Rep. Jung Sung-kook introduced legislation to postpone the effective date to January 2030.
Despite these objections, Lee's nomination and public backing suggest the incoming administration intends to move forward with taxation, positioning it as essential for revenue collection and market integrity. The government's commitment signals a definitive shift toward treating cryptocurrency income as taxable "other income" rather than continuing indefinite exemptions, marking a critical regulatory development for institutional investors operating in or exposed to South Korean digital asset markets.
