South Korea has reinstated heavy capital gains taxes for homeowners with multiple properties, causing tax burdens to increase by more than two times [1].
The move aims to curb real estate speculation and increase government tax revenue. However, the sudden spike in costs may discourage owners from selling, potentially reducing the supply of available homes in high-demand areas.
In Seoul's core districts, the impact is particularly stark. For an 84-square-meter apartment with a capital gain of 3.5 billion won, a two-home owner would face a final tax of 2.4 billion won [2]. A three-home owner selling the same property would see that tax burden rise to 2.8 billion won [3].
Market observers report that the window for quick sales has already closed. A real estate agent said the period of urgent sales ended two to three weeks ago and a wait-and-see approach now prevails [4].
Government officials acknowledged that a freeze in listings is likely in the short term. A government official said a phase of locked-in listings is inevitable due to the surge in tax burdens [5].
Despite these concerns, the government has dismissed the idea that the policy will permanently cripple the market. Officials said they are discussing ways to ensure that properties are released to actual residents rather than speculators [6].
Reporter Cha Yu-jeong said the reinstatement of heavy capital gains taxes has significantly increased the amount multiple homeowners must pay when selling their properties [7].
“Tax burdens on property sales could double.”
The reinstatement of these taxes creates a 'lock-in effect' where homeowners refuse to sell to avoid massive tax hits, which can paradoxically drive up prices for buyers due to limited supply. The government's challenge is to balance the goal of deterring speculation with the need to maintain a fluid market for genuine homebuyers.
