South Korea confirms Jan. 2027 launch for long delayed crypto tax

South Korea has finalized its 2026 tax reform package while keeping the planned 22% tax on cryptocurrency investment gains set to begin on Jan. 1, 2027.

• South Korea has finalized its 2026 tax reform plan without delaying the 22% crypto tax scheduled for Jan. 1, 2027.
• Annual crypto gains above 2.5 million won will be taxed at a combined 22%, with the first tax filings due in May 2028.
• Authorities said OECD crypto reporting rules will give South Korea access to overseas transaction data from 48 participating jurisdictions.
• Parliament can still amend or delay the measure as opposition lawmakers continue pushing to repeal the crypto tax.
• Financial regulators are also advancing a Digital Asset Basic Act to establish rules for stablecoins, exchanges and other digital asset businesses.

South Korea's Ministry of Economy and Finance confirmed on Aug. 3 that it had finalized the 2026 tax reform proposal without including another postponement for virtual asset taxation, clearing the way for the long-delayed measure to proceed next year if lawmakers approve the package in the National Assembly.

Under the current Income Tax Act, profits from transferring or lending virtual assets will be taxed as other income from Jan. 1, 2027. Investors will pay a 20% national tax, with an additional 2% local income tax, on annual gains exceeding 2.5 million won ($1,740). The first tax return covering crypto income earned during 2027 will be filed in May 2028.

The ministry also included an example showing how the tax would apply. An investor earning a 5 million won annual profit from Bitcoin trading would first deduct the 2.5 million won exemption before paying 22% tax on the remaining amount, resulting in a tax bill of 550,000 won.

The tax was originally scheduled to take effect in January 2022 after lawmakers approved amendments to the Income Tax Act in 2020. However, implementation was postponed three times, first to 2023, then to 2025, and later to 2027, as authorities cited incomplete reporting systems and unresolved administrative infrastructure.

Government officials now say those preparations have largely been completed.

The ministry pointed to the Organisation for Economic Co-operation and Development's Crypto-Asset Reporting Framework (CARF), under which South Korea expects to receive overseas virtual asset transaction data from tax authorities in 48 participating jurisdictions, including Japan, Germany and France, beginning next year. Officials said the international reporting system would significantly reduce blind spots involving offshore crypto transactions.

Finance Minister Koo Yun-cheol had already indicated during a National Assembly Finance and Economic Planning Committee meeting on July 29 that the government intended to proceed with the tax as scheduled while improving the system after implementation where necessary.

Although the government has finalized its proposal, the tax reform package still requires approval from the National Assembly before becoming law.

The ministry acknowledged that parliamentary discussions could still result in another delay or other legislative changes before the tax takes effect.

The opposition People Power Party continues to oppose the measure and has proposed amendments to remove crypto income from the Income Tax Act altogether. Party lawmakers have argued that taxing retail cryptocurrency investors while most retail stock investment gains remain exempt creates unequal treatment.

Earlier committee discussions also raised concerns over the current tax design. During the July 29 hearing, People Power Party lawmaker Kim Sang-hoon questioned the absence of rules allowing investors to carry forward trading losses, warning that the framework could encourage traders to move activity from domestic exchanges such as Upbit, Bithumb, Coinone and Korbit to overseas centralized exchanges, decentralized finance platforms or peer-to-peer markets.

Responding during the hearing, Koo said moving virtual assets into South Korea's capital gains tax framework would require a broader review of the country's financial tax system. He added that authorities could consider revisions after gaining experience with the tax's operation.

Separate from the tax package, South Korea is also preparing a wider regulatory framework for digital assets.

The Financial Services Commission told the National Assembly in late July that it is working with the ruling Democratic Party on a consolidated Digital Asset Basic Act. The proposed legislation would combine 10 pending digital asset and stablecoin bills into one framework covering stablecoin issuance, exchanges, disclosures, internal controls and system resilience.

Several issues remain unresolved, including ownership requirements for issuers of won-backed stablecoins and possible ownership limits for major cryptocurrency exchanges.

At the same time, the National Tax Service has established a dedicated digital asset unit and continues preparing implementation guidance for the upcoming crypto tax, according to previous government statements.

South Korea has also begun clarifying how other blockchain-based assets could be taxed.

In June, the Ministry of Economy and Finance said tokenized stocks should generally be treated as securities rather than virtual assets because their economic characteristics resemble conventional securities despite using blockchain technology.

The ministry said taxation could begin under existing securities tax rules once the Financial Services Commission formally determines that tokenized stocks qualify as securities. Officials also indicated that overseas-issued tokenized stocks could still fall under South Korean tax rules depending on the rights attached to the assets.

Meanwhile, tax authorities have been strengthening information-sharing arrangements with overseas counterparts. Alongside participation in the OECD's Crypto-Asset Reporting Framework, officials have previously said they are expanding cooperation with foreign tax agencies to improve oversight of cross-border digital asset transactions.

Unless lawmakers approve another postponement or pass the pending repeal proposal before the end of 2026, South Korea's 22% tax on annual cryptocurrency gains above 2.5 million won will take effect on Jan. 1, 2027, ending several years of repeated delays.
