South Korea's 22% tax on cryptocurrency gains remains on track to begin Jan. 1, 2027, after the ruling Democratic Party and the finance ministry failed on Oct. 28 to agree on whether to postpone it, the fourth such meeting to end without a decision, according to Yonhap.

For investors, the result is a law that still applies in two months and a political debate that could rewrite it. Any delay needs an Income Tax Act amendment passed before Jan. 1; until then, the 2027 date is the rule.

Rep. Oh Gi-hyoung of the Democratic Party told reporters after the meeting that officials agreed crypto income should be taxed but raised concerns, including fairness between users of domestic and overseas exchanges, Yonhap reported. He said the party would review the issues further before deciding. Two days later, after Democratic Party leaders met exchange chief executives at the National Assembly, Oh said the party should settle the question within one to two weeks, Inews24 reported. No decision had been announced as of Nov. 2.

What South Korea's crypto tax would cost investors

Under the current law, income from selling or lending virtual assets is netted across the year. Gains above a basic deduction of 2.5 million won (about $1,880) are taxed at 22%, a figure that includes the 2% local income tax, the Korea Herald reported. Individuals would file and pay on 2027 income for the first time in May 2028.

Losses can offset gains only within the same year. They cannot be carried forward, so an investor who loses heavily in one year and partly recovers the next could still owe tax while remaining behind overall, the newspaper noted. The U.S. and the U.K. let qualifying capital losses roll forward, and Japan's 2026 tax reform outline proposes a three-year loss carryover for certain crypto assets.

The levy was legislated in 2020 for a 2022 start and has been pushed back three times. The last postponement came in December 2024, when the National Assembly moved the start from January 2025 to January 2027, according to Blockhead.

The CARF argument for a 2029 start

The case for another delay rests largely on cross-border data. Korea is scheduled to begin exchanging crypto transaction information under the OECD's Crypto-Asset Reporting Framework (CARF) in 2027. Hong Kong and Singapore follow in 2028 and the U.S. in 2029, the Korea Herald reported.

Democratic Party lawmaker Park Min-gyu introduced a bill on Oct. 16, with 13 co-sponsors, that would start taxation on Jan. 1 of the second year after Korea's first CARF exchange, which would mean 2029, according to Blockhead. People Power Party lawmakers have separately proposed scrapping the tax or delaying it by two to three years, Blockhead reported. Several pending bills would push the start to 2029 or 2030, the Korea Herald said.

Exchanges also say they are not ready. Authorities and exchanges have held 49 consultations since 2022 without finishing reporting systems, according to materials from the office of People Power Party Rep. Park Soo-young cited by the Korea Herald. Bithumb, the country's second-largest exchange, estimated it would need six to nine months of development and testing once the government provides a test environment.

The tax agency disagrees that gaps abroad make collection impossible. At a parliamentary audit, National Tax Service Deputy Commissioner Park Hae-young said obtaining every record from decentralized or overseas platforms was difficult but that the agency would use CARF and overseas account data to minimize omissions, and complete an analysis system by the end of this year, the Korea Herald reported. Exchanges' first quarterly data submissions under the regime are due at the end of May 2027.

A petition seeking a two-year delay drew more than 53,000 supporters and was referred to the National Assembly's finance committee in September. Korea's crypto market has also shrunk: its reported value fell 33% in the six months to the end of June, to 58.9 trillion won, the Korea Herald reported. Seoul has also been pressing exchanges on custody, requiring more assets in cold wallets after the Binance hack.

What investors should do before Jan. 1

The practical advice is the same whichever way lawmakers go: keep records. Under the current rules, coins held before the start date get an opening cost based on a prescribed market value at the start, if that exceeds the original purchase price, according to a National Tax Service guide summarized by crypto.news, so holdings at the boundary need to be documented. Investors who bought tokens offshore and moved them to a Korean exchange face a specific gap: the local platform may record the deposit without knowing the original cost needed to calculate a gain, the Korea Herald noted.

Access to history varies. One exchange offers records dating to 2019, while another limits downloads to a year and 15,000 entries, the Korea Herald's editorial board wrote. That argues for exporting statements now. Treatment of staking, airdrops and decentralized-finance income also remains unclear under the law's transfer-and-lending categories. The National Tax Service told lawmakers on Oct. 13 that it was preparing detailed guidance for around November, Blockhead reported.

Finance and Economy Minister Lee Hyeong-il has said the government will weigh views from industry and the National Assembly.
