PANews reported on March 12 that, according to the Korea Times, the Korean National Tax Service announced it has begun preparations to build a tracking system for taxing cryptocurrency investment gains. The project, with a budget of 3 billion won (approximately US$2.02 million), aims to analyze virtual asset transactions and implement corresponding taxes. System design will begin in April, with trial operation starting in November, and a formal launch expected between November and December. It will be used to collect personal virtual asset transaction data starting in 2027.

The National Tax Service plans to use AI and machine learning to analyze and track abnormal transaction types and patterns, and will share virtual asset analysis data and lists of suspected violators with agencies such as Korea Customs, the Ministry of Statistics and Data, and the Bank of Korea. Starting next January, virtual asset income exceeding 2.5 million won will be subject to a comprehensive tax rate of 22%.
