The South Korean National Tax Service (NTS) has announced an intensified crackdown on cryptocurrency tax evasion, including assets stored in offline cold wallets. The NTS plans to use blockchain analysis tools to track on-chain transactions of suspected tax evaders. If assets are believed to be hidden offline, the agency will conduct searches and seize devices such as hard drives, cold wallets, or personal computers. Over the past four years, the NTS has seized and liquidated crypto assets worth 146.1 billion won (approximately $108 million) from 14,140 tax delinquents.
