South Korea is preparing to tax cryptocurrency profits at an effective rate of 22% next year, raising new questions about how the country treats investment income at a time when some investors are reassessing the relative risks of stocks and Bitcoin.
The debate is unfolding after South Korea’s stock market, which had benefited from enthusiasm over artificial intelligence and semiconductor exports, began experiencing sharp swings. Samsung Electronics, South Korea’s largest company and a major global producer of memory chips, and SK Hynix, a leading supplier of advanced memory used in AI servers, had helped drive the market higher.
That momentum later weakened, and repeated circuit breaker activations underscored the scale of the volatility. During parts of the decline, Bitcoin recorded smaller losses than the domestic stock market, drawing attention from investors who had long regarded cryptocurrency as the more unstable asset.
The comparison does not mean Bitcoin has become safer than stocks, nor does it prove that South Korean investors are moving money out of equities and into digital assets. It does show that the recent stock market turmoil has changed how some investors evaluate Bitcoin.
Rather than focusing only on short term gains from smaller cryptocurrencies, some South Korean investors have begun purchasing fixed amounts of Bitcoin at regular intervals. The strategy reflects an effort to treat the largest cryptocurrency as a longer term holding, even though it remains highly volatile.
The tax will affect a broader group than younger speculative traders. According to data from South Korean financial authorities, 10,810 people held more than $700,000 in virtual assets as of August 5 last year. Investors in their 50s formed the largest group with 3,994 people, followed by those in their 40s with 3,086, people aged 60 or older with 2,426 and investors in their 30s with 1,167.
More than 11.15 million people were eligible to trade virtual assets as of the end of June. That figure does not represent the number of active Bitcoin investors, but it shows that cryptocurrency investment in South Korea now extends well beyond a narrow group of young traders.
Under the current law, annual profits exceeding about $1,750 from the sale or lending of cryptocurrencies will be taxed at a national rate of 20%. Local taxes will raise the effective rate to 22%.
The tax has been postponed through the end of this year. The South Korean government’s latest tax revision proposal did not include another delay, meaning profits generated from 2027 will become taxable unless the National Assembly changes the existing law.
The planned rollout has revived a fairness debate. South Korea abolished its planned financial investment income tax on certain gains from stocks and other financial products, but it kept a separate tax on cryptocurrency profits.
Critics argue that the government is applying different standards to investors depending on the asset they choose. That argument could become more politically significant as Bitcoin attracts not only short term traders but also older investors and people using regular purchase strategies.
The government also faces practical challenges. Authorities will need to track transactions conducted through overseas exchanges, verify acquisition costs and prevent investors from hiding taxable income outside domestic platforms.
South Korea’s Deputy Prime Minister and Finance Minister Koo Yun-cheol has said the government plans to introduce the tax next year and revise the system if problems emerge after implementation.
The central issue is therefore not whether Bitcoin has replaced South Korean stocks as a safer investment. It has not. The issue is that a sharp reversal in a market once lifted by AI and semiconductor optimism has made Bitcoin’s relative performance harder for investors to ignore, just as the government prepares to tax the profits they may earn from it.
