South Korea Tax Agency Seeks Real-Time Crypto Tracker
South Korea’s National Tax Service opened a tender for real-time crypto transaction-tracking software to detect tax evasion, with a budget of 146.5 million won and bids due April 28–30.
South Korea’s National Tax Service opened a public tender for real-time transaction-tracking software aimed at detecting crypto tax evasion. The procurement sets a budget of 146.5 million won, including value-added tax, and requests bid submissions for April 28–30. The agency requires delivery within 30 days of contract signing and set a proposal evaluation date of May 7.
The procurement notice names the contract as ‘virtual asset tax evasion response transaction-tracking software licenses’ and provides few technical specifications in the public notice.
The NTS scientific investigation unit described the software’s intended capabilities as real-time monitoring of virtual asset transactions, visualization of transfers between wallet addresses and exchanges, and tools to support probes into hidden assets, offshore tax evasion, and unreported inheritance or gift transfers. The notice says the software should trace flows across wallets and centralized trading venues and present transaction paths in a format usable for tax investigations.
Earlier this year the NTS issued a separate bid for an AI-backed system to analyze large volumes of crypto trading data. That tender requested a platform able to process high transaction volumes to flag suspicious activity and support enforcement work.
South Korea plans to implement a crypto gains tax in January 2027. Under the current design, individual gains above 2.5 million won would face a combined 22% levy, comprising a 20% income tax and a 2% local tax. The policy has been delayed several times and faces political opposition; the main opposition People Power Party has proposed scrapping the planned tax, citing concerns about fairness, potential double taxation and enforcement.
The procurement notice does not specify vendor qualifications, data sources or technical standards for linking on-chain data to exchange records and other off-chain information. The NTS is expected to provide further procurement details to bidders during the tender process.
