[Editorial] Crypto tax dilemma

South Korea’s planned levy on cryptocurrency income is due to begin on Jan. 1 after three postponements since lawmakers approved it in 2020.

With the deadline approaching, the government is again weighing whether to proceed. Another delay would expose years of drift, but enforcing a tax before authorities can verify liabilities would create a different set of problems.

The current system would allow a basic deduction of 2.5 million won ($1,890) from annual income earned by selling or lending digital assets, with the remainder taxed at 22 percent, including local income tax.

On paper, the arrangement is simple. In practice, even basic records are uneven. Data supplied by major exchanges show that none has completed its tax-reporting system. Investors’ access to transaction histories also varies. One platform offers records dating to 2019, while another limits access to a year and 15,000 entries.

The problem goes beyond software. Cryptocurrency transactions include arrangements conventional tax rules do not neatly capture, such as staking rewards and decentralized-finance transactions.

Clear methods for valuing and reporting such activity are essential to helping taxpayers calculate what they owe and enabling tax officials to verify their returns. Requiring payment first and clarifying the rules later would invite disputes that the state is poorly equipped to resolve.

Cross-border enforcement is another weak point. Korea is set to begin exchanging crypto-asset information under the OECD’s reporting framework in 2027. Singapore and the United Arab Emirates are due to join in 2028; US participation is scheduled for 2029.

If taxation begins before those gaps narrow, the Korean government may have a far better view of trading on domestic exchanges than of activity abroad. That discrepancy would reward opacity and disadvantage compliant local investors.

Tax treatment of perpetual futures on overseas exchanges also remains legally unclear. A ruling-party lawmaker has proposed delaying implementation until 2029, when the US is due to join the system.

Yet postponement has its own cost. The levy was enacted six years ago, and each delay was justified by the need for better preparation. Repeating the same explanation in 2026 invites a question: What has all that extra time accomplished?

The tax design deserves revision, too. Annual gains can be reduced by losses incurred in the same year, but losses cannot be carried forward to offset gains in later years.

Someone who loses heavily one year and recovers only part of that amount the next may still owe tax despite remaining in the red overall. This rule can leave investors paying tax even when their cumulative returns remain negative.

The scrapping of the planned financial investment income tax has left domestic stock investors under a different regime, sharpening complaints that digital assets face a heavier tax burden.

The government’s recent shift from firm assurances to consultations reflects pressure from investors, many of them young, and political parties. Their concerns merit attention, but tax policy cannot be shaped by electoral calculations alone. Another postponement without tangible progress would further undermine public confidence.

A fourth delay would be justified only if it came with a firm timetable for fixing the system’s shortcomings. Exchanges need reliable reporting systems, taxpayers need clear rules for different types of transactions and authorities need effective access to overseas trading data. Without these basics, setting a new start date would leave the same problems unresolved.

The National Assembly should also move ahead with the Digital Asset Basic Act to establish clear rules for the market before tax enforcement begins.

A credible tax system depends on rules that can be enforced fairly and consistently. Announcing another start date will mean little unless the government uses the extra time to make those rules workable.
