South Korea opposition proposes delaying 22% crypto tax from 2027 to 2030

South Korean opposition lawmaker Jeong Seong-guk has proposed delaying the country’s 22% cryptocurrency investment tax from its scheduled 2027 start date to 2030, days after the government told the National Assembly it intends to proceed with the levy as planned, setting up a fresh standoff over a tax that has already been postponed three times since 2020.

South Korea crypto tax faces fresh political battle

The proposed South Korea crypto tax delay does not seek to erase the tax provisions entirely.

Instead, it would preserve the framework while pushing back the date when cryptocurrency investment income becomes taxable.

Jeong has argued that authorities should establish a system taxpayers can understand and accept before imposing the levy.

The proposal creates another avenue for opposition lawmakers, who have also introduced legislation seeking to abolish cryptocurrency income taxation altogether.

The timing is significant. On July 29, Deputy Prime Minister and Minister of Economy and Finance Koo Yun-cheol told the National Assembly’s Strategy and Finance Committee that the government was moving ahead with virtual-asset taxation as scheduled.

“We are pushing ahead to tax virtual assets (cryptocurrencies) starting next year as scheduled,” Koo said.

That position puts the government directly at odds with the latest push to postpone the South Korea crypto tax until 2030.

South Korea crypto tax would hit gains above 2.5 million won

Under the current framework, income generated from transferring or lending cryptocurrencies such as Bitcoin and Ethereum will be treated as other income beginning Jan. 1, 2027.

The South Korea crypto tax rate would effectively be 22% on annual taxable gains above 2.5 million won, combining a 20% national income tax with a 2% local income tax.

For example, an investor who makes 5 million won in taxable cryptocurrency gains would first deduct the 2.5 million won basic allowance. The remaining 2.5 million won would then face the 22% rate, producing a tax bill of 550,000 won.

The first reporting and payment would occur in May 2028 for income earned during 2027.

South Korea crypto tax has already been delayed three times

The latest proposal would mark another chapter in a long-running South Korea crypto tax saga.

The taxation system was legislated in 2020 and initially scheduled to begin in 2022. Authorities subsequently moved the start date to 2023, then 2025 and finally 2027. Concerns over taxation infrastructure, reporting mechanisms and the broader regulatory environment have repeatedly been cited during the delays.

The government now argues that much of the necessary infrastructure is sufficiently advanced to proceed.

That includes preparations to collect cryptocurrency transaction information and strengthen cross-border tax reporting.

South Korea is also part of the OECD-led Crypto-Asset Reporting Framework, which is designed to improve automatic information exchange involving crypto-asset transactions.

The OECD says 48 jurisdictions signed the initial multilateral agreement in 2024, while a broader group has committed to implementing CARF and beginning exchanges on a 2027–2028 timetable.

South Korea crypto tax debate puts investors in the crossfire

The political dispute goes beyond a simple question of whether investors should pay tax.

Critics argue that the South Korea crypto tax could create an uneven system if cryptocurrency gains are taxed differently from other investment income.

Concerns have also focused on the treatment of losses and whether investors will face tax liabilities despite suffering losses across different years.

South Korean reporting has highlighted criticism that the existing framework does not allow losses to be carried forward.

Supporters of implementation, however, argue that postponing the levy indefinitely would undermine regulatory certainty and leave a rapidly expanding asset class outside the tax system.

For investors, the immediate issue is uncertainty. The government wants the South Korea crypto tax to begin in 2027, while opposition lawmakers want three more years to reconsider the framework.

The final decision will now rest with the National Assembly. Until lawmakers settle the dispute, South Korea’s cryptocurrency market faces an uncomfortable reality: the 22% tax remains scheduled for 2027, but another dramatic delay—or even abolition—has returned to the political agenda.
