South Korea moves toward another crypto tax delay
South Korea is leaning toward postponing its long-planned tax on cryptocurrency gains for a fourth time, pushing the start date back to 2029, according to a report from Newsis citing unidentified officials.
The levy, currently due to begin in January 2027, would tax annual net income from crypto transfers or lending at 20%, or 22% once local income tax is included, after a deduction of 2.5 million won ($1,887). The National Tax Service still lists 1 January 2027 as the official start date, but that now looks increasingly uncertain.
The presidential office is said to favour a delay because of concerns that the burden would fall disproportionately on users of South Korean exchanges. The core problem, officials told the outlet, is that authorities would struggle to track trading activity on U.S. platforms until cross-border data sharing begins.
“Almost half of the crypto market is the U.S.,” one official said, describing the absence of American tax data as the single biggest obstacle to a fair rollout.
Parliament must approve an amendment to the law before any delay can take effect, and a final decision is expected by early December. Ruling Democratic Party lawmaker Park Min-kyu has already proposed moving the start date to 1 January 2029, according to local media.
A reversal from the government’s summer position
The deliberations mark a notable shift in the government’s stance. As recently as July, Deputy Prime Minister Koo Yun-cheol told lawmakers that the tax would take effect in January 2027 as scheduled.
Koo has since been replaced. His successor, Lee Hyung-il, struck a markedly different tone at a parliamentary audit on 6 October, telling lawmakers he would gather views from parliament, experts and industry before committing to a timetable.
The tax has already been postponed three times since it was first legislated for 2022. Each delay has required parliamentary action, and a fourth would follow the same route.
The policy reversal reflects an awkward reality for Seoul: South Korea has one of the world’s most active retail crypto trading populations, yet it cannot see where much of that trading actually happens. If the tax had launched in January 2027, the government would have had full visibility over domestic exchange activity but only partial visibility over holdings and trades routed through U.S. platforms, which by the officials’ own account account for nearly half the global market.
That asymmetry would have created what is effectively a two-tier system: domestic exchange users fully taxable and traceable, while traders who moved their activity to U.S. venues could largely escape scrutiny. The concern is not hypothetical. Korean traders have a long history of shifting volume to offshore platforms whenever domestic rules tighten, a pattern seen most dramatically during past regulatory crackdowns.
The government had previously argued it could track offshore holdings through foreign financial account reporting requirements, which oblige Korean taxpayers to declare overseas assets above certain thresholds. Officials now appear to accept that this mechanism is insufficient for a market as liquid and fragmented as crypto.
The CARF timetable driving the decision
The delay is rooted in the staggered global rollout of the OECD’s Crypto-Asset Reporting Framework, or CARF, the international standard for automatic exchange of crypto tax information between jurisdictions.
Under the OECD timetable, South Korea, Japan and the United Kingdom are due to begin exchanging data in 2027. Singapore, Switzerland and Hong Kong follow in 2028. The United States will not start until 2029.
That three-year gap between Seoul’s own compliance date and Washington’s is the crux of the problem. If South Korea’s tax begins in 2027, the country would be taxing crypto gains at exactly the moment its largest data-sharing partner is still dark.
Not every country has taken the same view. The United States, the United Kingdom and Japan already tax crypto gains without waiting for cross-border data exchanges to come online. Their tax authorities rely instead on domestic reporting obligations, voluntary disclosure and enforcement action against evasion.
South Korean officials, by contrast, appear to have concluded that enforcement without American data would be both inequitable and administratively futile. With nearly half the market out of reach, the argument goes, the tax would function less as a levy on crypto gains and more as a penalty on choosing a Korean exchange.

What a 2029 delay would mean
A fourth delay would extend what has become one of the longest-running policy sagas in Asian crypto regulation. The tax was first legislated to begin in 2022, meaning that by 2029 Korean crypto investors will have gone seven years under a regime of announced but never implemented taxation.
For Korean exchanges, the delay would be a reprieve. Upbit, the country’s dominant platform, and its smaller rivals have repeatedly warned that a poorly designed tax would accelerate the exodus of volume to offshore venues, undermining both their business and the government’s eventual revenue take. A delay to 2029 aligns the tax with the CARF data they need to compete on level terms.
For the Treasury, the calculus is less comfortable. Every postponement costs potential revenue and invites criticism that the government is soft on a sector that has generated substantial wealth for a broad base of retail investors. The 2.5 million won deduction, roughly $1,887, was already framed as protection for small traders, and the 20% rate is in line with the treatment of other financial gains.
The political dimension matters too. The ruling Democratic Party’s willingness to sponsor a delay bill, through Park Min-kyu’s proposal, suggests the government expects to carry the amendment through parliament without significant resistance. Opposition parties have historically been split between demanding immediate implementation and arguing for outright abolition of the tax, and a delay to 2029 may be the compromise both sides can tolerate.
There is also a precedent question. If South Korea delays because the U.S. data-sharing starts in 2029, other jurisdictions in the 2027 CARF cohort may face similar pressure. Japan and the United Kingdom both tax crypto already, but their enforcement agencies will confront the same American blind spot through 2028. Seoul’s reasoning could become a template for governments that have legislated crypto taxes but lack the cross-border plumbing to enforce them fairly.
The closing read
The likely delay says something uncomfortable about the state of global crypto tax policy: the framework exists, the political will arguably exists, but the plumbing does not. CARF was designed to make crypto taxation borderless, yet its staggered rollout has left early adopters enforcing a tax that late adopters can quietly evade. South Korea has chosen, provisionally at least, not to ask its own citizens to shoulder that asymmetry.
The decision expected by early December will not end the debate. A 2029 start date simply moves the question two years down the road, and it hands Korean traders a longer window in which gains remain untaxed at the national level. Whether that window encourages market participation, as exchanges hope, or simply entrenches offshore migration until the data flows, is the question Seoul will be watching either way.
For now, the National Tax Service’s calendar still says January 2027. Parliament has until December to decide whether that date survives a fourth round of scrutiny.
