South Korea’s National Tax Service (NTS) has initiated preparations to deploy an AI system to track cryptocurrency profits. The government plans to collect taxes on digital asset gains starting January 2027. The project aims to strengthen oversight of virtual asset transactions and prevent tax evasion.
The AI system will integrate transaction data from exchanges and other trading platforms. It will analyze large volumes of cryptocurrency trading records efficiently. Authorities aim to detect unusual patterns and identify undeclared income promptly.
The project has a budget of approximately 3 billion won, equivalent to $2.02 million. Bids for the system have been posted on the government’s electronic procurement platform. A contractor is expected to be selected and contracted by the end of March.
AI System Development and Timeline
System design is scheduled to start in April following the contractor’s selection. Testing will run throughout the year to ensure the platform functions accurately. A pilot operation is planned for November, with full launch expected between November and December.
The NTS intends to collect and manage transaction data systematically using AI. The platform will enable authorities to conduct detailed audits of cryptocurrency investors. By analyzing behavioral patterns, AI can flag transactions likely linked to tax evasion.
The system will use machine learning to continuously improve detection of irregular trading. It will identify hidden income from taxpayers failing to report profits. Integration with other government systems will enhance comprehensive monitoring of the digital asset market.
Crypto Tax Enforcement and Background
South Korea’s cryptocurrency tax framework has been delayed multiple times since its approval in 2020. Lawmakers debated implementation timelines due to industry opposition and disagreements over tax thresholds. The current plan sets a 20% income tax plus a 2 percent local tax on gains exceeding 2.5 million won.
The AI system will allow the NTS to share data with other agencies efficiently. Partners include the Korea Customs Service, the Ministry of Data and Statistics, and the Bank of Korea. Coordinated oversight is expected to improve compliance and reduce unreported cryptocurrency profits.
Authorities plan to use AI insights for audits and monitoring across multiple platforms. The system’s predictive analysis will identify transactions that deviate from normal patterns. AI-driven enforcement is central to the government’s strategy for the 2027 crypto tax rollout.
