South Korea’s Housing Market: Will Taxing Multi-Homeowners Actually Work?
South Korean President Lee Jae-myung recently reiterated his commitment to enforcing stricter capital gains taxes on multi-homeowners, starting May 9th. The core idea? To encourage those with multiple properties to sell, thereby increasing housing supply. But a deep dive into the data reveals a complex picture – one where this policy has historically had limited impact on overall housing availability and may have inadvertently exacerbated wealth inequality.
A History of Tax Adjustments and Limited Results
The use of differential taxation on multi-homeowners isn’t new in South Korea. Introduced initially under the Roh Moo-hyun administration in 2004, it was subsequently eased or abolished by subsequent governments before being revived in 2017 under President Moon Jae-in. The current administration’s move to reinstate the tax, framed as “normalizing the abnormal,” begs the question: has this approach ever truly worked?
Data from the National Data Service (formerly Statistics Korea) shows that in 2017, when the Moon administration reintroduced the tax, 15.3% of households owned two or more properties. Despite the policy, this figure increased to 15.5% in 2019. It wasn’t until the tax rate was raised to a maximum of 30% in 2020 that the percentage began to decline, falling to 14.6% in 2021. However, even then, the absolute number of multi-homeowners actually increased during this period, reaching 3.145 million.
When the Yoon Suk-yeol administration temporarily suspended the tax in 2022, the impact was minimal. The multi-homeowner ratio dipped slightly to 14.4% in 2022, then edged up to 14.6% in 2023 and 14.8% in 2024, demonstrating a consistent level of stability – or, arguably, stagnation – in the number of individuals owning multiple properties.
Did you know? The nationwide ‘multiple property ownership index’ recently hit a 2-year, 7-month low, but this doesn’t necessarily indicate a significant shift in the overall market dynamics.
The Rise of the “Strongest Single Home” Phenomenon
Experts argue that the focus on taxing multi-homeowners has had unintended consequences. “Instead of increasing supply, these policies have sent the wrong message to the market, intensifying the ‘strongest single home’ phenomenon,” explains Lee Chang-moo, a professor of urban engineering at Hanyang University. This refers to the tendency for individuals to concentrate their wealth in a single, high-value property, often in prime locations, rather than diversifying their investments.
This trend is clearly reflected in the widening gap between the prices of the most and least expensive apartments. The ‘nationwide apartment price quintile ratio’ – a measure of the price difference between the top 20% and bottom 20% of apartments – jumped from 7.1-7.3 between 2013-2016 to 8x in 2017, coinciding with the reintroduction of the multi-homeowner tax. This ratio continued to climb, reaching 12.7 in 2021.
The suspension of the tax under the Yoon administration saw a slight decrease in this ratio in 2022 (11.7), but it has since stabilized around 12.8, indicating a persistent level of price disparity. Eun-hyung Lee, a research fellow at the Korea Construction Policy Research Institute, notes that “the market responded to the regulatory pressure by concentrating assets in preferred residential areas, leading to a flow of capital away from regions that needed it most.”
Looking Ahead: What Can We Expect?
Experts predict that the reinstatement of the tax will likely result in a limited number of forced sales, primarily from those facing financial difficulties or those who purchased properties speculatively. Jun-seok Go, a professor at Yonsei University’s School of Business, cautions that “while some properties may come onto the market before the tax takes effect, it won’t be enough to significantly stabilize the housing market. Instead, we’re likely to see a further concentration of wealth in Seoul’s most desirable neighborhoods, exacerbating the affordability crisis.”
The focus, therefore, needs to shift beyond simply penalizing multi-homeowners. Sustainable solutions require a multi-faceted approach, including:
- Increased Housing Supply: Focusing on building more affordable housing, particularly in areas with high demand.
- Regional Development: Investing in infrastructure and economic opportunities in regional areas to reduce the concentration of wealth and population in Seoul.
- Tax Reform: Considering broader tax reforms that address wealth inequality and promote fair taxation across all asset classes.
