South Korea reinstated a heavy capital gains tax system for owners of two or more homes starting May 10, 2026 [1, 2].
The policy aims to curb real estate speculation and alleviate the current shortage of available properties by increasing the financial burden on multi-homeowners [1, 2].
Under the new regulations, the government applies a surcharge on top of the basic capital gains tax rate, which ranges from six% to 45% [1]. For individuals owning two homes, an additional 20 percentage points are added to the basic rate [1, 2]. Those owning three or more homes face a steeper surcharge of 30 percentage points [1, 2].
These changes can significantly increase the total tax owed upon the sale of a property. Reporter Cha Yu-jeong said that for some owners of three or more homes, the capital gains tax burden has more than doubled [1].
To illustrate the impact, a sale of a property in the Banpo Xi area of Seoul would see a tax increase for a two-home owner from 1.3 billion won to 2.4 billion won [2]. This example highlights the scale of the financial shift for high-value real estate transactions in the capital.
"Starting today, the heavy capital gains tax system for multiple homeowners is being applied again," a YTN anchor said [1]. The move reflects a strategic shift by the government to stabilize the housing market through aggressive taxation of investors.
“Two-homeowners face an additional 20 percentage points, while those with three or more face 30 percentage points.”
The reinstatement of these surcharges signals a return to a restrictive fiscal policy intended to force speculators to sell their holdings. By dramatically increasing the cost of exiting a property investment, the government is attempting to increase the supply of homes on the market, though such measures can sometimes lead to a 'lock-in effect' where owners refuse to sell to avoid the tax hit.
