South Korea crypto tax 2027: 22% on gains above KRW 2.5 million

Key takeaways

• Under current law, the South Korea crypto tax starts on January 1, 2027. Gains from transferring or lending virtual assets above KRW 2.5 million a year are taxed at 20%, or 22% once local income tax is added.
• The tax has been postponed three times since it was written into the Income Tax Act in 2020. A fourth delay now looks increasingly possible, but no decision has been made.
• The opposition People Power Party wants the tax repealed or delayed. Ruling Democratic Party lawmakers have filed their own delay bill, and the government says it will "fully consider" the calls.
• Many lawmakers want the tax to wait for the Digital Asset Basic Act. That bill would cover won stablecoins and exchange licensing, but it has not yet been submitted to the National Assembly.
• Losses cannot be carried forward under the current design. This is one of the main reasons investors and exchanges are pushing back.

What is the South Korea crypto tax, and when does it start?

South Korea's crypto tax is due on January 1, 2027: gains from transferring or lending virtual assets above KRW 2.5 million a year would be taxed at 20%, or 22% with local income tax. It has been delayed three times since 2020, TokenPost reported.

As of October 23, 2026, the legal start date is still January 1, 2027. In its 2026 Tax Reform Plan, published on August 3, the Ministry of Economy and Finance chose not to propose another deferral, The Asia Business Daily reported. Deputy Prime Minister and Finance Minister Koo Yun-cheol said at the time that taxation would go ahead on schedule and could be adjusted once it was running.

The first tax returns and payments would be due in May 2028, covering gains made during 2027. That is one month after South Korea's general election in April 2028, a timing point noted by The Asia Business Daily.

Who would pay, and how much?

The tax would apply to individuals who make net gains from transferring or lending virtual assets. Each taxpayer would get a basic deduction of KRW 2.5 million per year. Only the amount above that would be taxed: 20% national income tax plus 2 percentage points of local income tax, for a combined 22% (Cointelegraph, CoinGeek).

The Asia Business Daily gave a worked example. An investor who makes a KRW 5 million profit trading Bitcoin in a year would have KRW 2.5 million of taxable gain after the deduction. At 22%, that is a tax bill of KRW 550,000.

According to The Korea Times, the government has argued that about 85% of investors hold virtual assets worth less than KRW 5 million. On that basis, officials say most investors would owe little or no tax once the deduction is applied.

Coins bought before 2027

Coins bought before the tax starts get special treatment. Under current law, their acquisition cost is the higher of what the investor actually paid and the market price on December 31, 2026, Bloomingbit reported. The aim is to keep gains built up before the start date out of the tax base. The National Tax Service still has to publish its detailed guidance. The Block reported that the agency plans to finalise a draft notice by October 30 and to issue a public notice in November.

Why both parties now want a delay or repeal

The politics have shifted quickly. In May, the finance ministry said the tax would go ahead. By October, officials were signalling that they were open to another delay.

The opposition's case

The People Power Party (PPP) has made deferral its official position, MoneyToday reported. On March 19, PPP lawmaker Song Eon-seok introduced an amendment that would delete the crypto tax provision entirely. His argument is that taxing crypto is unfair when most ordinary stock investors pay no tax on their gains, especially after the planned financial investment income tax was scrapped. At an October 22 parliamentary audit, Song said the tax should be abolished or put off until the Digital Asset Basic Act is in place, noting that the government's draft of that bill had not even been released.

Another PPP lawmaker, Park Soo-young, held a news conference with crypto investors on October 21 and called for a two-year delay to January 2029. "We must not kick away the ladder young people use to build assets," he said, according to the Seoul Economic Daily.

The ruling party's shift

The Democratic Party of Korea (DPK) supported the 2027 start for most of the year. In September, senior policy committee member Min Byung-duk said he agreed with the principle of taxing income but proposed waiting until the Digital Asset Basic Act passes. He pointed to two problems: income on overseas exchanges is hard to track, and losses cannot be carried forward. On October 16, DPK lawmaker Park Min-kyu filed a bill to move the start to 2029, co-sponsored by 12 DPK lawmakers and one Rebuilding Korea Party lawmaker, the Seoul Economic Daily reported. Party leader Kim Min-seok has said the party should reach a conclusion within the year.

The government's position

Officially, the government has not decided. Financial Services Commission (FSC) Chairman Lee Eog-weon told an October 22 parliamentary audit that the government would take "various circumstances into full consideration" (The Block, MoneyToday). A senior official told the Seoul Economic Daily that the position was not final and that the government would watch the National Assembly's tax subcommittee. The official also referred to the burden of an issue affecting "as many as 11 million investors."

The investor and market backdrop

The pressure partly reflects the size of Korea's retail crypto market and how much it has cooled. The figures below come from the Financial Supervisory Service (FSS), as reported by Korean media.

The investor count includes duplicate accounts across exchanges, so the number of unique people is lower. A survey by Tiger Research and Chainalysis, cited by The Korea Times, found that 73.7% of 2,423 Korean crypto investors opposed the tax plan.

The practical problems behind the push for a delay

• Proving acquisition cost. Investors must show what they paid, but overseas exchanges may keep records for only a few months, The Asia Business Daily reported.
• Cross-border data. Korea will receive overseas trading data under the OECD's Crypto-Asset Reporting Framework (CARF) from next year. However, the United States, the largest market, is not expected to take part until 2029.
• No loss carryforward. Losses offset gains only within the same year. In The Asia Business Daily's example, an investor who loses KRW 40 million in one year and gains KRW 50 million the next would be taxed on KRW 47.5 million in year two, even though the net profit over both years is only KRW 10 million. The United States and United Kingdom allow carryforwards, and Japan plans three-year carryforwards from 2028.
• Exchange readiness. The Digital Asset eXchange Alliance (DAXA), which represents the major exchanges, has also asked for a delay. It cites unresolved questions about cost-basis systems and rules for different types of transactions.

How the Digital Asset Basic Act ties into the timing

The Digital Asset Basic Act is the government's planned second-stage crypto law. In July, the FSC said it planned to draft a consolidated bill with the ruling party, bringing together about ten separate digital asset and stablecoin bills, Cointelegraph reported. The bill would cover stablecoin issuance and circulation, exchange licensing, disclosure, internal controls and system resilience. On October 22, Chairman Lee said consultations were in their "final stage" and that the government would introduce the bill as soon as possible. No filing date has been announced.

Two disputes have held the bill up. Neither is settled in any public text.

• Who can issue won stablecoins. The Bank of Korea has proposed that only consortiums in which commercial banks hold at least 51% should be allowed to issue them. The FSC and many DPK lawmakers have argued that non-bank fintech and blockchain firms should also be able to issue, The Korea Times reported.
• Exchange ownership caps. In January, the FSC was reviewing a cap of roughly 15% to 20% on major shareholders' stakes in crypto exchanges, Cointelegraph reported. Exchange operators and some ruling party lawmakers have resisted the idea. A 5 billion won minimum capital requirement for stablecoin issuers was reported to have broader agreement.

Supporters of a delay say the tax system depends on this law. Without it, the legal definition of a virtual asset and the reporting duties of exchanges remain unclear. First Vice Finance Minister Kwon Dae-young said on October 20 that tax infrastructure and market-discipline systems must be in place for taxation to take root. The industry read this as a link to the Basic Act, the Seoul Economic Daily reported.

Confirmed law versus proposals

What it means

For now, the law has not changed: gains made from January 1, 2027 are taxable unless the National Assembly amends the Income Tax Act before then. With a little over two months left, the tax subcommittee's review in November is the key moment to watch. Lawmakers will also be watching the ruling party's November 2 forum on the digital asset market, which the finance ministry has agreed to attend.

If the tax is delayed, the debate moves to the conditions for a new start date: the passage of the Digital Asset Basic Act, wider CARF data coverage, and possibly loss carryforwards. If it goes ahead, the National Tax Service's guidance on acquisition costs and exchange reporting will matter most for investors keeping records.
