The Korean National Tax Service is comprehensively tracking cryptocurrency tax evasion, including non-custodial wallets.

According to Mars Finance, market sources indicate that the Korean National Tax Service has issued a tender notice, planning to introduce cryptocurrency transaction tracking software from institutions such as Chainalysis and TRM Labs. This software will enable real-time monitoring of cryptocurrency transaction records, tracking of hidden assets by suspected tax evaders, and combating disguised inheritance, gifts, and offshore tax evasion using cryptocurrency. The system can track approximately 70 million cryptocurrency assets, including Bitcoin, Ethereum, XRP, and stablecoins, covering 45 blockchain layers. It also possesses the ability to de-mix cryptocurrency to identify money laundering techniques such as "mixers" and can perform a certain degree of identity verification on non-custodial wallets such as MetaMask and Phantom. This is the third time the National Tax Service has introduced such a solution since 2024, with system construction planned for completion in June and official deployment starting in July.
