South Korea's Evolving Capital Market Needs a Rationalized Tax System

Returning to South Korea after years abroad, the author was struck by the "Korea Discount" – the phenomenon of seemingly sound companies trading at inexplicably low stock prices. While aware of the term, the sheer undervaluation of many firms, despite basic financial health, was surprising. Compounding this was the peculiar tax system: profits from stock investments were largely untaxed, a stark contrast to the principle that income should be taxed wherever it is generated.

Even though I had only heard of the 'Korea Discount' vaguely, the stocks of seemingly sound companies were trading at unbelievably low prices.

The author initially invested in the market, only to experience the harsh realities of its structural issues. Despite significant losses, he held on, believing the market would eventually correct itself. When the market finally rallied, yielding substantial profits, the lack of tax on these gains felt unsettling. He questioned the fairness of paying taxes on his salary while reaping untaxed profits from investments, especially when luck played a significant role, such as favorable semiconductor market trends.

The disparity in taxation between assets became even more apparent when comparing stocks to real estate. While acknowledging the different economic impacts, the author found the significant tax burden on real estate gains, often perceived as "unearned income," while stock gains were largely exempt, to be questionable. He also raised concerns about equity, noting that while some real estate gains come from long-held assets, stock market participation often requires a certain level of financial capacity, creating an uneven playing field.

Even if you make money by stock price appreciation, you don't have to pay taxes.

The article argues that the South Korean capital market has evolved and its tax system needs to adapt. Instead of relying on tax exemptions to attract investors, the focus should shift to rationalizing the tax code. The author proposes reducing transaction taxes and implementing a progressive tax on actual capital gains, potentially with incentives for long-term investment. He emphasizes the need for a long-term vision in designing tax policies that align with the nation's broader values, rather than focusing on minor adjustments to tax rates.

It's not that I'm saying we should just tax more across the board. What's needed is not simple tax increases, but a rationalization of the tax system.
