Deep Dive: July Tax Reform and BOK Warning - Real Estate Market Outlook amid Property Tax Hikes

Impending Tax Reform: Higher Property Tax Burden for Multiple Homeowners

The core of the tax reform proposal scheduled for release in July 2026 is 'tax normalization' and the suppression of speculative demand in the real estate market. With the distinct upward trend in apartment prices in Seoul and the greater metropolitan area, increased property taxes targeting multiple homeowners and high-value properties are being heavily considered.

The Ministry of Economy and Finance is currently discussing a phased increase in the fair market value ratio (currently at 60%), which reached up to 100% during the previous administration. This is based on the rationale that Korea's effective real estate holding tax rate is below the OECD average. Concurrently, the suspension of the capital gains tax surcharge for multiple homeowners ended on May 9th, meaning the tax burden on those in regulated areas will intensify in the second half of the year. The special deduction for long-term holding is also expected to be restructured to offer differentiated benefits based on actual residency, signaling a clear policy intent to phase out highly leveraged 'gap investments' from the market.

Clear Signal from the Bank of Korea: Household Debt and Financial Imbalance Risks

Coupled with stricter real estate taxes, the Bank of Korea (BOK) is closely monitoring the surge in household debt. In recent monetary policy board meetings and briefings, the BOK has made it clear that the increase in leveraged investments linked to rising housing prices in the metropolitan area is the most significant latent risk to the macroeconomy.

The government has already established a target to strictly cap the household debt growth rate in 2026 at within 1.5%, roughly half of the nominal economic growth rate. Accordingly, a robust deleveraging measure has been in effect since April, fundamentally restricting the extension of mortgage maturities for multiple homeowners and rental business operators in the capital region. The BOK is placing greater emphasis on 'resolving financial imbalances' rather than simply addressing the slowing inflation rate in its interest rate policy decisions. This suggests a highly cautious approach toward cutting the base rate to prevent excessive capital concentration in asset markets.

Second-Half Market Implications and Asset Allocation Strategies

With simultaneous pressure from tax and lending regulations, the housing market in the latter half of the year is highly likely to experience a contraction in transaction volume and a shift toward actual demand. Tax-evasive listings from multiple homeowners may enter the market, and the sentiment for speculative buying of high-priced apartments is expected to dampen significantly due to rising financing costs.

• Real Estate Market: The preference for 'one premium property' will intensify, potentially diverting demand toward residential properties in unregulated areas or income-generating real estate that are relatively free from tax and lending constraints.
• Portfolio Rebalancing: As the expected return on the housing market decreases due to taxes and interest costs, liquidity is highly likely to shift toward safe assets like savings deposits or asset classes generating stable cash flows, such as high-quality domestic and foreign dividend stocks and infrastructure funds.

In conclusion, the July tax reform and the Bank of Korea's household debt management stance are factors that will increase short-term market volatility. As the influence of macroeconomic indicators and policy variables maximizes, a conservative approach focused on securing liquidity and managing debt is required, rather than aggressive asset accumulation using excessive leverage.
