TL;DR
South Korea is preparing to launch its long‑delayed crypto tax framework on January 1, 2027, marking the end of a multi‑year debate over how to treat gains from virtual asset trading. Deputy Prime Minister Koo Yun‑cheol reaffirmed the government’s position during a National Assembly Finance and Economy Committee meeting, saying officials expect the current timetable to hold. He added that authorities may adjust specific rules after implementation if practical issues appear once filings begin.
The Income Tax Act requires the country to tax profits from cryptocurrency and other virtual asset transactions starting in 2027, following three postponements. Policymakers originally planned to introduce the crypto tax in January 2022 but delayed the rollout because exchanges, tax agencies, and investors lacked the infrastructure needed for accurate reporting.
Under the present framework, investors will receive an annual deduction of 2.5 million won. Gains above that threshold will face a 20% national rate, with local taxes potentially lifting the total burden to 22%. Authorities plan to classify virtual asset profits as other income, giving digital asset activity its own calculation process rather than combining it with employment or business earnings.

Taxpayers will calculate gains by subtracting eligible acquisition costs from disposal proceeds, a process that may require detailed records from domestic and overseas platforms. Domestic exchanges are expected to play a central role in supplying transaction data, while investors who trade across multiple accounts may need to reconcile prices, fees, and transfers. Overseas holdings could add extra reporting duties when local records do not capture full histories.
People Power Party lawmaker Kim Sang‑hoon questioned the absence of loss carryforward deductions, warning that the rule could weaken domestic trading demand. Koo said the government could revisit the issue after the crypto tax begins, noting that stock investment rules also limit loss carryforwards under certain classifications.
Some lawmakers and investors want crypto profits treated like capital gains, similar to systems used overseas. Koo said any change would require a broader review of the capital market, including stocks, funds, derivatives, and related tax rules. For now, the government is keeping the 2027 start date in place while leaving room for technical refinements.
