Key Takeaways
- • South Korea's crypto tax, scheduled to take effect January 1, 2027, will not allow losses from prior years to be carried forward and deducted from later gains, drawing growing backlash according to Korea JoongAng Daily.
- • Crypto income from selling or lending assets will be taxed at 22 percent including local income tax, after necessary expenses and a 2.5 million won basic deduction.
- • Under the rule, an investor down 50 million won over two years would still owe more than 10 million won in tax on the second year's 50 million won gain.
- • Korea's tax treatment of crypto diverges from stocks: a 10 million won stock gain carries no capital gains tax, while the same crypto gain would owe 1.65 million won.
- • The ruling Democratic Party moved toward a delay on October 15, with Rep. Park Min-kyu preparing a bill to postpone the tax to 2029, while the finance minister declined to confirm the tax would proceed as planned.
Summary
The crypto tax framework, introduced through a revision to the Income Tax Act in December 2020, is scheduled to take effect on January 1, 2027, after three prior delays. According to Korea JoongAng Daily, the central controversy concerns the absence of a loss carryforward provision. Gains and losses within the same year can be netted, but losses cannot be carried into the following year. The publication illustrates the effect: an investor losing 100 million won ($74,900) in one year and earning 50 million won the next would owe 10.45 million won in tax on the second year's gains, despite being down 50 million won overall.
Critics argue this runs counter to the principle that taxes should be imposed based on income earned. The article notes that the United States allows unused capital losses from crypto to be carried forward indefinitely, citing research by the National Assembly Research Service. Germany permits deduction of losses from private asset disposals against same-category gains in later years, and Japan has revised its tax law to introduce separate taxation of crypto income at 20 percent with a three-year loss carryforward.
The article also highlights a disparity between stocks and crypto. A retail investor earning 10 million won from domestically listed stock sales pays securities transaction tax but no capital gains tax, whereas the same gain from spot crypto trading would owe 1.65 million won after expenses. The government originally paired crypto taxation in 2020 with a financial investment income tax that would have expanded taxation of stock gains while reducing the securities transaction tax. That stock tax was later abolished while the crypto tax was kept, and calls have grown for a transaction tax on crypto instead of an income tax.
Enforcement concerns center on information exchange. According to data Rep. Kim Sang-hoon of the main opposition People Power Party obtained from the National Tax Service, Korea will begin exchanging information under the Crypto-Asset Reporting Framework in 2027, while Singapore and the UAE will not start until 2028 and the United States until 2029. Authorities can verify domestic exchange income against operator-submitted data, but may face delays for some overseas trades.
Legislative momentum for delay is building. The PPP has submitted competing bills led by Rep. Kim to delay the tax and by Rep. Song Eon-seog to scrap it. The ruling Democratic Party moved toward a delay on October 15, with Rep. Park Min-kyu preparing a bill to postpone the tax to 2029, saying, "We should delay taxation of digital assets and focus on enacting the basic act on digital assets." Finance Minister Lee Hyoung-il said at his confirmation hearing last month that taxation next year would be desirable, but at an October 6 parliamentary audit he said only that the government would gather a range of views, a response that has raised market attention to a possible fourth postponement.
