The South Korean National Tax Service (NTS) has expanded its crypto tax enforcement to include cold wallets, signifying a significant shift in the nation’s approach to virtual asset regulation. Previously, the focus was solely on assets held within exchanges, but this new move targets offline devices like hardware wallets, raising questions about how users store their cryptocurrency. This development comes as South Korea continues to see robust growth in its crypto market, with trading volumes soaring from $730 million in 2020 to a whopping $4.7 billion in 2025. The NTS has the authority to conduct home searches and seizures of cold wallets suspected of hiding assets, potentially impacting cryptocurrency storage practices. This move reflects increased scrutiny by authorities in response to concerns about tax evasion. The NTS has already seized over $108 million from over 14,000 individuals since 2021 as part of this initiative. The enforcement has led to a ripple effect on the market as users are encouraged to verify their holdings with exchanges and anticipate potential regulatory actions or even asset sales. The South Korean government’s proactive approach in this area may influence similar measures by other countries, potentially impacting crypto industry compliance and operational norms globally.
