Gyeonggi, South Korea's most populous province, has recovered $4.6 million from 2,390 crypto tax evaders out of the 5,910 identified, thanks to a new digital tracking system. The system uses the local registration number of delinquents to reveal their mobile numbers, which are then used to track linked accounts on crypto exchanges. The system has reduced the previous six-month process of requesting information from crypto exchanges to just 15 days. South Korea has been investigating some firms for tax evasion while repeatedly delaying the implementation of its tax policies on crypto earnings.
