South Korea's crypto tax is on course to take effect on 1 Jan 2027 after the Ministry of Economy and Finance declined to extend a further deferral in its 2026 tax reform bill unveiled on 3 Aug, putting virtual-asset gains on track for a combined 22% levy.
South Korea's 22% Crypto Tax on Track for 2027 as Ministry Rejects Fresh Delay

Korea ranks among the world's deepest crypto trading pools, with won pairs regularly ranking among the most-traded and Upbit repeatedly placing in the top tier of spot exchanges by volume. The behavioural question is what Korean crypto investors, who have paid no such levy to date, will do.
The taxation plan stays untouched
The 2026 reform bill's headline changes centred on property taxation; on crypto, the package contains no new provisions. Previous administrations had used the annual tax reform bill to write in deferrals as supplementary clauses, most recently in December 2024. This year, the finance ministry chose not to include one, leaving in place the design the 2024 amendment fixed.
The first filing window opens in May 2028. The design is not settled until the National Assembly's tax subcommittee finishes work in November, and the annual reform package is traditionally finalized only in late December.
For coins bought before implementation, the acquisition cost will be recognized as the higher of the actual purchase price or the market price on 31 Dec, resetting the base for pre-existing holdings. An investor who buys Bitcoin (BTC) for 10mn won (around $7,000) and sells for 20mn won ($14,000) in the same year would owe tax on 7.5mn won ($5,250), the profit less the 2.5mn won ($1,750) deduction.
A fourth delay is off the table
Originally legislated in December 2020 for a 2022 rollout, the levy was pushed back to 2023, then 2025 and again to 2027, each time citing infrastructure gaps and investor backlash.
Deputy Prime Minister and Finance Minister Koo Yun-cheol told the National Assembly's Finance and Economic Planning Committee on 29 Jul that the government would proceed as planned and refine the regime after implementation. He pushed back on calls to reclassify crypto gains as capital gains, noting that South Korea does not operate a capital-gains tax system the way other countries do, including the US, Japan and the UK.
Stocks scrapped, crypto could be next
The main opposition People Power Party (PPP) has made abolition its party line. Under the financial investment income tax scrapped in December 2024 before it ever took effect, listed-stock gains would have been taxed at the same 22% headline rate only above an annual 50mn won ($35,000) deduction, 20 times the 2.5mn won ($1,750) threshold now facing crypto investors.
A citizen petition seeking repeal cleared the 50,000-signature threshold in May and was referred to committee; a similar petition was refiled last month.
Offshore moves meet a tighter net
Moving offshore does not remove the levy. Korean residents owe tax on virtual-asset disposals wherever they occur, and from 2027 the National Tax Service (NTS) will receive offshore trade data through the OECD's Crypto-Asset Reporting Framework (CARF), an information-exchange system that currently covers 48 participating jurisdictions.
Even so, offshore flows are already building. Data the Financial Supervisory Service submitted to the National Assembly show Korea's five biggest exchanges (Upbit, Bithumb, Coinone, Korbit and Gopax) recorded 2.76tn won ($1.9bn) in stablecoin outflows to overseas venues in June against 2.20tn won ($1.5bn) in inflows, for a net outflow of 560.3bn won ($392mn).
June marked the 18th consecutive month of net outflows since January 2025, a run that predates the ministry's 3 Aug reform package. Korea's five biggest exchanges are spot-only, while foreign venues offer high-leverage crypto derivatives, tokenized traditional assets and DeFi services unavailable at home.
