PANews reported on May 11 that, according to Cryptopolitan, the South Korean National Tax Service is building an AI system costing approximately $2.2 million to track cryptocurrency transactions and track tax evaders, with completion expected by the end of 2026. The system will integrate exchange transaction records with blockchain data to identify suspicious transactions such as money laundering, undeclared gifts, and offshore tax evasion, and will extend its tracking scope to non-custodial wallets. The National Tax Service is coordinating implementation details with five major exchanges, including Upbit and Bithumb, with final tax guidelines expected by the end of 2026.

A survey by South Korea's Financial Services Commission shows that the country has verified over 11 million crypto investors, but the growth rate has slowed significantly, with the growth rate of tradable accounts dropping from 25% in the first half of 2024 to 3% in the second half. The South Korean government has confirmed that it will levy a 22% tax on crypto asset gains starting January 1, 2027, with annual gains exceeding approximately $1,800 subject to taxation. This tax has been postponed twice from its original 2025 implementation date.
