The tax details for cryptocurrency in South Korea are still unclear, and every step of exchanging BTC for USDT on overseas exchanges may be subject to taxation

According to South Korean media MK, the annual tax reform plan previously announced by the South Korean government does not include a proposal to further postpone the taxation of virtual assets (cryptocurrencies), which means that the current legal schedule for taxation in 2027 is likely to remain.

According to the current South Korean Income Tax Act, starting in 2027, income from the transfer and lending of virtual assets will be classified as "other income," and investors will enjoy a tax-free allowance of 2.5 million Korean won per year. Any amount exceeding this will be subject to a 20% income tax, along with an additional 10% local income tax, resulting in a combined tax rate of 22%.
