South Korea to Impose 22% Crypto Tax from 2027, No Loss Offsets Allowed

South Korea will begin taxing crypto gains at a combined 22% rate from Jan. 1, 2027, the government confirmed, ending months of speculation that the long-delayed measure might be postponed again. Deputy Prime Minister and Finance Minister Koo Yun-cheol told the National Assembly Finance and Economy Planning Committee on July 29 that the schedule is moving ahead as planned. Under the Income Tax Act, gains from transferring or lending virtual assets will be treated as “other income.” Annual gains above 2.5 million won (roughly $1,740) will be subject to a 20% national tax plus a 2% local levy — a 22% combined rate. Investors whose yearly gains stay below the 2.5 million won threshold will be tax-exempt. Taxpayers will file their first returns in May 2028 for income earned in 2027. A long road to implementation The levy was first approved in 2020 and was originally slated to start in January 2022. Lawmakers postponed that rollout several times — first to 2025 and then, via a December 2024 amendment, to 2027. The National Assembly approved the most recent delay through revisions to the Income Tax Act. Political pushback and migration risks People Power Party lawmaker Kim Sang-hoon pushed back on the tax design during the committee hearing, warning that the framework does not let investors offset losses against future gains. He said that restriction could push traders off domestic exchanges such as Upbit, Bithumb, Coinone and Korbit and toward overseas centralized exchanges, DeFi platforms or peer-to-peer markets — reducing onshore trading volumes and tax visibility. Kim argued authorities should wait until the OECD’s Crypto-Asset Reporting Framework (CARF) is fully operational so cross-border tax information can be exchanged. Koo acknowledged those concerns but said converting crypto into a capital-gains style regime would require a broader review of how financial markets are taxed. He left open the possibility of future revisions after officials collect operational data under the new system. Legislative uncertainty remains An opposition bill introduced in March seeks to remove crypto income from the Income Tax Act entirely. That proposal was referred to a subcommittee on July 29, so repeal or another delay remains legally possible through the end of 2026. Wider regulatory and market context The tax confirmation arrives amid broader conversations about digital-asset rules and stablecoin policy. On July 29, Hashed Open Research and the Solana Policy Institute published a policy report urging interim stablecoin licensing guidance while lawmakers negotiate the Digital Asset Basic Act. Their recommendations include temporary rules for issuance, payments, permitted activities and treatment of foreign-issued tokens — advisory guidance, not changes to law, intended to give businesses clearer guardrails for won-backed stablecoins. State-backed tech investment is also expanding. The government approved plans for a 20 trillion won investment account under the Korea Investment Corporation that can invest domestically in AI, data centers and other strategic industries — a departure from KIC’s traditionally overseas-focused portfolio. How this compares internationally South Korea’s approach differs from the U.S., where the IRS generally treats digital assets as property and allows capital losses to offset capital gains (subject to tax rules). South Korea’s apparent lack of loss carryforward provisions could leave active traders with a less flexible tax position compared with some foreign investors. U.S. users of Korean platforms should monitor whether exchanges change access, reporting or product offerings ahead of 2027. What exchanges and traders should do now Domestic exchanges will need to build reporting infrastructure and update compliance systems. With the repeal effort still alive and potential tweaks to loss treatment on the table, the framework could change before it takes effect — but unless the National Assembly intervenes, the 22% crypto tax will kick in Jan. 1, 2027.
