The Citizens' Coalition for Economic Justice (Kyungsilnyeon) has raised concerns over South Korea's long-term holding special deduction (long-term hold deduction) policy, which allows property sellers to receive up to 80% tax deduction, claiming that it exacerbates the preference for 'one solid property' and inflates real estate prices in Gangnam, a wealthy area in Seoul. They presented a simulation indicating that a property sold in Gangnam could yield a profit of over 10 billion KRW, while the tax burden would only be around 700 million KRW due to the deduction policy in place. Kyungsilnyeon held a press conference to discuss this issue, asserting that the increasing benefits for single homeowners implemented by the government have inadvertently led to a trend where affluent buyers accumulate properties in Gangnam. The long-term holding special deduction allows homeowners to benefit significantly from capital gains tax exemptions, particularly those who hold properties for over ten years and meet residency requirements. According to their analysis of a specific high-value apartment in Apgujeong, the property saw its price surge from 2.5 billion KRW in 2015 to 12.7 billion KRW last year, resulting in an unrealized profit of approximately 10.2 billion KRW before taxes. However, the effective tax burden on such profits is substantially reduced to about 7.6 million KRW. This favorable tax situation contrasts sharply with potential capital gains taxes in other markets, indicating a structural advantage for single-property owners in Gangnam compared to multi-property owners elsewhere in the country.
