South Korea Weighs Delaying Crypto Gains Tax Until 2029

The Block reported, citing South Korean outlet Newsis, that the presidential office is discussing another delay with relevant government agencies. The tax is currently scheduled to take effect on January 1, 2027, but the proposed new date would be January 1, 2029.

The government has not made a final decision. The issue is expected to move through inter-agency consultations before reaching the National Assembly for discussions on amendments to the tax law, according to the report.

The proposed timing would connect South Korea’s tax schedule to the rollout of the Organisation for Economic Co-operation and Development’s Crypto-Asset Reporting Framework, or CARF. The framework is intended to allow tax authorities in participating jurisdictions to automatically exchange information about digital asset transactions.

A tax plan repeatedly pushed back

South Korea introduced the cryptocurrency tax through an amendment to the Income Tax Act in 2020. Under the planned system, annual gains from transferring or lending crypto assets would be taxed at 22%, including local tax, after a basic deduction of 2.5 million won, or approximately $1,888, according to the report from The Block.

The measure was initially due to begin in 2022. It has since been delayed three times following objections from traders, exchanges and industry experts. Those objections have focused on whether the government has sufficient reporting infrastructure, how overseas activity would be verified and whether the rules could create unequal treatment between investors using domestic and foreign platforms.

The latest proposal would not simply establish another politically chosen date. It would tie the tax’s launch to the availability of cross-border reporting infrastructure.

A bill introduced by Democratic Party lawmaker Park Min-gyu takes that approach directly. The bill’s stated rationale, reproduced from National Assembly Open API data by the bill record on PoliWiki, would link the start of crypto taxation to the year in which international crypto-asset information is first exchanged. That mechanism effectively points toward 2029 under the current discussions.

International data is the central obstacle

The practical challenge is that South Korean authorities can obtain transaction information from domestic exchanges more readily than from overseas platforms or decentralized exchanges. Without comparable data from major jurisdictions, officials could be required to investigate individual transactions or place greater reporting obligations on taxpayers.

Newsis reported that the presidential office considers the absence of US trading data the most significant obstacle to an earlier start. The concern is that a domestic tax system could be formally active while authorities lack the information needed to verify whether taxpayers have accurately reported transactions conducted abroad.

That issue also raises questions about fairness. Investors who use South Korean exchanges could face more consistent reporting and monitoring than those who hold assets through foreign platforms. A system that relies heavily on individual declarations could therefore impose more compliance work on some users while leaving gaps in the treatment of others.

The OECD’s 2025 monitoring and implementation update describes CARF as a coordinated international reporting system and says committed jurisdictions are generally expected to begin exchanging information in 2027 or 2028. The staggered rollout means national tax authorities may have to decide whether to proceed with incomplete data or wait until more countries are able to participate.

Industry warns of an uneven system

The case for another delay is being challenged by the need to provide certainty to investors and businesses. Domestic exchanges and other industry participants have urged the government to reconsider the timing, according to a Newsis report on the debate. Their argument is that exchanges need time to prepare reporting systems, but repeated postponements also make it harder for companies and users to plan around a stable tax regime.

Industry concerns extend beyond software development. Exchanges may need to determine how to calculate gains across different assets, account for transfers between wallets and distinguish taxable disposals from movements that do not represent a sale. Users with accounts across several platforms could face additional complexity when records do not match.

The criticism is therefore not simply opposition to taxation. It is a warning that an incomplete system could produce unequal enforcement, particularly for people using overseas exchanges or decentralized finance services. That could undermine confidence in the tax rules even if the rate and deduction remain unchanged.

Finance Minister Lee Hyeong-il said the government was still collecting views from industry and experts and would make its decision carefully, according to Newsis. National Tax Service official Park Hae-young also acknowledged that obtaining complete information on overseas exchanges and decentralized exchange activity would be difficult.

A regional test for crypto taxation

South Korea’s debate illustrates a broader problem for governments attempting to tax assets traded across borders. Domestic legislation can establish a tax obligation, but effective enforcement depends on institutions exchanging usable data at compatible times.

A delay until 2029 could give South Korea more time to align its rules with CARF and reduce the gap between domestic reporting and international enforcement. It would also prolong uncertainty for traders and exchanges that have already prepared for earlier start dates.

The outcome will help show whether crypto taxation follows domestic political timetables or the slower construction of international financial infrastructure. For South Korea, the decision is not only about when to collect tax. It is also about whether the system can do so consistently across the increasingly global market in which its investors operate.
