South Korea's presidential office considers fourth crypto tax delay, targeting 2029 start tied to U.S. data sharing

South Korea's presidential office is reviewing a fourth postponement of the 22% crypto gains tax, originally scheduled for January 1, 2027. Lawmakers and industry groups are pushing for a 2029 start date, citing the absence of U.S. crypto transaction data as the main bottleneck. Under the OECD framework, South Korea will begin exchanging data in 2027, but the United States will not join until 2029, making the tax implementation difficult without reciprocal data sharing.
