South Korea to deploy crypto wallet tracing tools ahead of 2027 tax enforcement

South Korea's National Tax Service is preparing to deploy commercial cryptocurrency tracing software to track digital asset movements between private wallets ahead of a long-delayed 22% crypto tax set to take effect on January 1, 2027. While the tax agency admits tracking self-custodied assets remains difficult, it plans to utilize the OECD's Crypto-Asset Reporting Framework to gather overseas transaction data by 2028. Despite ongoing political opposition and warnings of capital flight from lawmakers, the government is moving forward with its implementation timetable.
