South Korea’s five largest crypto exchanges — Upbit, Bithumb, Coinone, Korbit, and Gopax — are already working with the National Tax Service to build reporting systems ahead of a major policy shift set for January 2027.
The coordination signals that the government is serious this time, after years of delays and political fights over whether to tax digital assets at all.
Government Draws A Hard Line
The Ministry of Economy and Finance confirmed the policy will go ahead as planned, rejecting calls to push the deadline back again or scrap the tax entirely.
Moon Kyung-ho, director of the ministry’s income tax division, said at an emergency forum in Seoul that the virtual asset tax would be implemented in January as scheduled.
He also defended the 20% rate, arguing it is, in some ways, more favorable to taxpayers than comprehensive taxation would be.
The tax applies to annual crypto profits above 2.5 million won — roughly $1,800. Gains beyond that threshold will be taxed at 20%, with an additional 2% local income tax, bringing the combined rate to 22%.

Profits from both transferring and lending virtual assets fall under the new rules, classified as “other income” under the updated Income Tax Act. The crypto tax will remain separate from financial investment income taxes.
Officials estimate the policy will affect around 13.26 million investors — a number that reflects just how embedded crypto trading has become in South Korean financial life.
Tracking Transactions Across Borders
One of the bigger concerns surrounding the policy involves trades made outside the country — on overseas exchanges, decentralized platforms, and peer-to-peer networks, where transaction data is harder to collect.

Officials said those cases can be handled through foreign financial account reporting requirements and the global Crypto-Asset Reporting Framework, known as CARF.
The government also pushed back on claims of double taxation. Authorities explained that capital gains taxes on crypto profits and VAT charged on exchange service fees cover different things, so the two charges should not be treated as overlapping.
New Income Types Still Need Rules
Not everything is settled. The government said it will release separate tax standards for staking rewards, airdrops, and lending income — newer forms of crypto earnings that don’t fit neatly into existing categories. Those guidelines have not yet been published.
Compliance rules and detailed reporting systems are still being developed by the National Tax Service and the five major exchanges ahead of the rollout.
South Korea ranks among the most active retail crypto markets in the world, and the January 2027 deadline now appears firm.
