Driven by a surge in virtual asset trading, South Korea is taking decisive action against tax evasion. The National Tax Service (NTS) is deploying sophisticated tracking systems to identify hidden crypto assets as the number of investors and daily trading volume both skyrocket. 10.77 million individuals now actively invest in virtual assets, with daily trades surpassing ₩6.4 trillion, reflecting a significant shift in South Korea’s financial landscape. However, this growth has opened doors for tax evasion, as cryptocurrencies increasingly become tools to conceal wealth. Following legal recognition of their economic value and amendments to the Specific Financial Information Act, authorities are intensifying efforts against illicit activities. 5,741 high-value tax delinquents were identified in 2021, leading to a recovery of over ₩71.2 billion through asset seizures. The crackdown continues to target overseas transfers, with ₩78.9 trillion worth of crypto leaving local exchanges for foreign wallets in the first half of 2025. Suspicious activity is also on the rise, with South Korea’s Financial Intelligence Unit (FIU) and Korea Customs Service (KCS) receiving over 36,684 suspicious transaction reports from local virtual asset service providers between January and August 2025. These developments highlight the urgent need for robust measures to combat tax evasion in the growing crypto industry.
