South Korea will reinstate a punitive capital-gains tax for multiple-home owners starting Sunday, with maximum effective rates reaching 82.5% [1].
The policy shift ends a four-year exemption period intended to stabilize the housing market. By increasing the cost of holding multiple properties, the government aims to curb speculative buying and address chronic housing shortages in high-demand urban areas.
The new tax regime applies to regulated areas nationwide, including all of Seoul and 12 designated districts in Gyeonggi-do [2]. Under the current system, base capital-gains tax rates range from six% to 45% [1]. However, the reinstatement introduces significant surcharges based on the number of properties owned.
Owners of two homes will face an additional surcharge of 20 percentage points [1]. Those owning three or more homes will see a surcharge of 30 percentage points [1]. Furthermore, a local income tax of 10% is added on top of the national tax [1].
These combined layers create a steep financial burden for investors. For example, a property owner realizing a capital gain of 1 billion KRW could be required to pay over 800 million KRW in taxes [1].
"Multiple-home owners will be subject to the additional tax rate," reporter Park Ki-wan of YTN said [2]. Park said that if a person makes 1 billion KRW in profit from a market price difference, it means they must pay over 800 million KRW in taxes [2].
The transition period ends today, May 9, with the higher rates taking effect tomorrow, May 10 [2]. While the government views this as a tool to discourage speculation, some market analysts suggest the move could inadvertently tighten housing supply by discouraging owners from selling their properties.
“Maximum effective rates reaching 82.5%”
The reinstatement of these punitive taxes signals a return to aggressive government intervention in the real estate market. By targeting 'speculative' owners with a tax rate that captures the vast majority of profits, the state is attempting to force a correction in housing prices. However, such high rates often lead to a 'lock-in effect,' where owners refuse to sell properties to avoid the tax hit, potentially reducing the volume of available homes on the market and keeping prices elevated despite the policy's intent.
