Korean Retail Investors Push Back Against Proposed Cut in Major Shareholder Threshold

The Korean government’s plan to lower the threshold for defining a major shareholder—from KRW 5 billion (approx. USD 3.8 million) to KRW 1 billion (approx. USD 760,000)—is sparking strong opposition from domestic retail investors. The move, which would significantly expand the number of investors subject to capital gains tax, is part of the Ministry of Economy and Finance’s push to “normalize the taxation system in capital markets,” but critics argue it directly contradicts earlier policy guidance encouraging asset shifts from real estate to equities.

Under the proposed change, anyone holding over KRW 1 billion in a single stock would be classified as a major shareholder and be liable for capital gains tax of up to 22%. Retail investors claim this would severely limit portfolio diversification and disproportionately penalize long-term investors. The new threshold, they argue, would create a year-end rush to sell shares to avoid taxation—exacerbating market volatility and undermining investment stability.

While government officials have downplayed the impact by emphasizing that “only a small number of high-value investors will be affected,” market participants refute this, pointing out that the rule applies per stock, not across total holdings. For example, holding KRW 1 billion in Samsung Electronics alone could trigger major shareholder status—even if the investor holds no other shares. This structural detail, critics say, reveals a fundamental flaw in the policy and reflects a lack of understanding of actual investment behavior.

Some commentators have dismissed the backlash by arguing that “retail investors don’t have KRW 1 billion,” but experienced investors say such comments ignore the reality of long-term investment growth and the increasing number of middle-class retirees with sizable equity portfolios. Many also warn of cascading side effects: tax-induced market timing, concentration avoidance, and ultimately, capital flight from Korea’s stock market.

Comparisons to foreign tax regimes further fuel the controversy. In the U.S., capital gains tax is applied based on holding period, not investor status. Long-term holdings are taxed at lower rates (15–20%), and no arbitrary major shareholder classification distorts market behavior. Critics of the Korean system argue that this discrepancy encourages investors to shift capital to U.S. markets, where tax rules are more consistent and predictable. The recent surge in Korean investment into U.S. equities is cited as a consequence of such structural disadvantages.

Politically, the issue is gaining traction as the Democratic Party becomes increasingly sensitive to public sentiment ahead of key local elections scheduled for next year. Party insiders acknowledge that mishandling this issue could erode trust among retail investors, a broad and vocal segment of the electorate. Several lawmakers have already called for a re-evaluation of the policy, and legislative battles are likely to intensify in the coming months.

Ultimately, this is not just a tax reform debate—it is a test of how seriously the government takes investor protection and the future competitiveness of Korea’s capital markets. Experts call for a broader overhaul of capital gains taxation, emphasizing fairness, consistency, and transparency. Without such reform, many warn, Korea risks losing its retail investor base to more stable and investor-friendly markets abroad.
