South Korea Confirms 22% Crypto Tax Will Start In 2027

South Korea’s Ministry of Economy and Finance has confirmed that virtual asset taxation will begin on Jan. 1, 2027, ending fresh speculation that the long-delayed rules could be postponed again. The tax will apply to annual crypto gains above 2.5 million won, roughly $1,800, with a combined 22% rate.

The structure comes from the current Income Tax Act. Income from transferring or lending virtual assets will be classified as “other income,” with a 20% national tax and a 2% local income tax applied above the exemption threshold.

Moon Kyung-ho, director of the income tax division at the Ministry of Economy and Finance, told a National Assembly forum in Seoul that the government will proceed with crypto taxation from January as scheduled. Local coverage from Edaily also placed the number of affected investors near 13.26 million, based on cumulative Upbit membership data from late 2025.

Tax Guidance Is Being Prepared With Exchanges

The National Tax Service is preparing detailed guidance for the rollout, with local reports indicating that officials have held working-level meetings with South Korea’s five major exchanges: Upbit, Bithumb, Coinone, Korbit, and Gopax. The tax notice is expected to move through legislative review during 2026 before the first taxable year begins.

The rules are designed to capture gains from crypto transfers and lending. For assets held before the start date, South Korea’s tax guidance allows the acquisition cost to be based on the higher of the original purchase price or the market price on Dec. 31, 2026. That mechanism reduces the risk that investors are taxed on gains accumulated before the new system begins.

The first filings tied to 2027 income are expected during the May 2028 comprehensive income tax season. Exchanges are likely to play a central role in reporting, calculation support, and transaction-history access for local users.

Industry Pushback Remains Strong

The confirmation comes despite ongoing political pressure to delay or scrap the tax. Critics argue that South Korea removed its financial investment income tax for stock investors while keeping a low 2.5 million won exemption for crypto users. That difference has fueled claims that crypto investors are being treated more harshly than domestic stock traders.

Local tax-policy critics have also raised concerns about loss carryforward. Under the current structure, crypto investors can offset gains and losses within the same tax year, but losses cannot be carried into future years. That can create a harsh result for traders who lose money one year and recover only part of it the next.

The government’s counterargument is based on tax fairness and regulatory integration. Moon argued that delaying or abolishing virtual asset taxation would create fairness issues with wage earners, business income taxpayers, and corporate taxpayers already subject to taxes on crypto-related income. He also linked the policy to the broader process of bringing digital assets into the formal financial system.

South Korea’s Crypto Market Faces A Liquidity Test

The tax decision matters because South Korea is one of the world’s most active crypto markets. A recent South Korea trading-volume analysis showed won-denominated crypto trading accounting for roughly 30% of global spot volume, with Upbit and Bithumb dominating domestic activity.

That concentration makes the tax rollout especially important for local liquidity. If reporting becomes smoother and investors accept the framework, the market could absorb the change as part of Korea’s broader regulatory buildout. If traders see the rules as unfair or difficult to comply with, activity could shift toward offshore exchanges, peer-to-peer routes, or lower-visibility wallets.
