South Korea Deploys AI to Track Crypto Taxes Ahead of 2027 Rollout

South Korea’s National Tax Service (NTS) has taken a significant step toward enforcing its long-delayed cryptocurrency tax policies. A procurement notice published this week details plans to acquire software capable of real-time monitoring of crypto transactions, with the aim of curbing tax evasion. The contract, valued at 146.5 million won (approximately $99,500), will provide licenses for ‘virtual asset tax evasion response transaction-tracking software.’

According to the notice, bid submissions are open from April 28 to April 30, with evaluations scheduled for May 7. The software will reportedly allow tax authorities to visualize wallet transactions, track transfers between exchanges, and investigate hidden assets, offshore tax evasion, and unreported inheritance or gift transfers. An official from the NTS scientific investigation unit confirmed the system’s real-time capabilities to local outlet ZDNet Korea.

Preparing for the 2027 Crypto Tax

This move is part of South Korea’s broader preparations for a 22% tax on crypto gains, which is scheduled to take effect in January 2027 after multiple delays. Gains exceeding 2.5 million won (about $1,700) will be subject to a 20% income tax and a 2% local tax under the new framework. Initially planned for 2021, the implementation has been postponed amidst political debates and infrastructure challenges.

The tax policy remains a contentious issue. In recent months, South Korea’s opposition party proposed abolishing the tax entirely, citing concerns over fairness and enforcement. Critics argue that the policy disproportionately impacts smaller investors and creates inconsistencies compared to traditional financial product taxation, which exempts certain gains.

AI and Data Oversight: A Strategic Pivot

South Korea’s focus on AI-backed monitoring signals a strategic pivot toward more sophisticated enforcement mechanisms. In March, the NTS announced plans to develop AI systems capable of processing large volumes of crypto trading data. The system aims to enhance oversight across exchanges, which are already subject to stringent transparency requirements under the Act on the Protection of Virtual Asset Users, implemented in July 2024. This act mandates rigorous reporting and compliance standards for exchanges, including 5-minute asset checks and bank-level user verification protocols.

The new tax monitoring system underscores the government’s commitment to harmonizing innovation with regulatory discipline. “The stakes are high,” said one industry analyst. “South Korea is positioning itself as a global leader in crypto regulation, but the success of these measures will depend on their ability to balance enforcement with market growth.”

What’s Next?

South Korea’s crypto tax rollout is set to go live on January 1, 2027, barring further delays or legislative changes. However, with political resistance mounting and technological infrastructure still under development, the path to implementation remains uncertain. The upcoming bid evaluations in early May will provide a clearer picture of the government’s timeline for deploying its new monitoring tools.

For traders, the implications are clear: South Korea is tightening its grip on digital assets, and regulatory compliance will be non-negotiable. Investors operating in the region should keep a close eye on developments, particularly as tax enforcement mechanisms evolve in the lead-up to 2027.
