South Korea Tax: 22% Crypto Levy Covers Private Wallets, Foreign Exchanges

The legislation created a virtual asset transfer service category covering businesses that move digital assets between South Korea and foreign jurisdictions through purchases, sales or exchanges. Crypto exchanges, custodians and other businesses providing qualifying transfer services can fall within the registration regime.

Government data has shown why overseas platforms and private wallets have become important to regulators. Financial Services Commission figures covering the second half of 2025 showed that South Korean exchanges recorded substantial crypto outflows as assets moved to foreign platforms and self-custody, with outflows reaching $60 billion during the period.

The Finance Ministry reiterated that digital asset taxation should begin in 2027 under the basic tax principle that income should be taxed where it arises.

Officials said they would continue reviewing detailed implementation standards and tax administration procedures to make sure the system is ready for the scheduled start.

The NTS has completed development of a tax-source management system and is building an integrated analysis system to support enforcement, according to the responses submitted to Kim's office.

Preparations have also involved the country's major domestic trading platforms. In May, crypto.news reported on tax preparations that the NTS was working on detailed guidance with Upbit operator Dunamu, Bithumb, Coinone, Korbit and Gopax. The guidance was expected to address transaction records and other data needed to calculate taxable digital asset income.

Under the current rules, the tax will apply to income generated from Jan. 1, 2027. The first full filing period for affected investors is expected in May 2028 for income earned during the previous year.

The 2027 date followed several delays to South Korea's crypto tax regime. The tax was introduced through amendments to the Income Tax Act. It was repeatedly postponed as lawmakers debated reporting infrastructure, investor burdens and the size of the basic deduction.

Political opposition has continued ahead of implementation. The People Power Party introduced legislation in March seeking to abolish the planned tax, arguing that applying the levy to digital assets while other forms of investment income receive different treatment creates an unfair burden for crypto investors.

A separate public petition calling for repeal later exceeded 50,000 signatures, triggering a National Assembly committee review in May. The petition challenged the 2.5 million won deduction and argued against taxing crypto investment gains while South Korea does not impose the same system on gains from stocks and bonds.

The government has continued preparing for implementation. No clear opposition to the scheduled start has emerged from the ruling party.

Not every form of crypto income has received a final tax treatment.

The Finance Ministry and NTS said they were still reviewing how the tax framework should apply to digital assets obtained through staking, lending, airdrops and hard forks, taking into account the different characteristics of each activity.

Crypto distributed free of charge by an exchange could already face tax in some circumstances. Authorities said assets qualifying as goods or prizes under the Income Tax Act may be taxed as other income.

Such classifications could become important because crypto income can arise without a conventional asset sale. Staking rewards, protocol distributions and assets created through chain splits can involve different acquisition dates and cost bases, requiring separate standards for determining when taxable income arises and how it should be valued.

The government has not provided an estimate for how much revenue the digital asset tax could generate. Both the Finance Ministry and NTS told Kim's office that producing a reasonable estimate or projection of expected tax revenue remains difficult.
