Korea weighs higher property holding taxes as housing heats up

Why the tax debate returned

Signs of speculative buying have reappeared in Seoul, with prices rising and listings scarce despite tougher lending rules and the expansion of speculative zones. President Lee Jae Myung has urged officials to mobilize every available tool to curb unproductive demand ahead of local elections in June. The message points to a harder line on housing policy after a period when regulatory tightening failed to cool demand in the capital’s most expensive districts.

Policymakers now frame the problem as a mismatch in the tax code. Taxes on owning property remain low by the standards of advanced economies, while taxes on selling property rank among the highest. That mix discourages owners from listing their homes, reduces market turnover and concentrates demand in desirable neighborhoods.

Finance officials say the current structure has frozen activity. They argue that a market where it is inexpensive to hold a home but costly to sell one traps supply, especially in Seoul’s premium areas. Brokers report thin inventory, frustrated buyers and frequent bidding over limited stock. The wider social backdrop is a familiar one in Korea: a highly urbanized country with half the population tied to the Seoul region for jobs, schools and services, and a supply pipeline that has struggled to keep pace.

The debate is returning at a delicate time. Mortgage caps, higher interest rates and a new wave of regulatory designations were meant to cool the market. Instead, the rebound in activity hints that financial and zoning levers alone may not tame demand when the incentives in the tax system still steer owners to hold and wait. That is why the administration is again weighing higher taxes on property ownership, alongside supply measures and potential changes to transaction levies.

How Korea taxes property today

Korea’s ownership tax has two layers: a local property tax paid to municipalities and a nationwide comprehensive real estate tax that applies to higher value holdings. The structure and definitions matter because they control who pays, on what base and at what rate.

Local property tax

The local property tax applies to a portion of the government assessed value. In most cases, the taxable base is 60 percent of the appraised value set by authorities, not the market price. Rates are progressive, roughly from 0.1 percent to 0.4 percent, with the top rate applied to properties in higher value brackets. Because the taxable base starts below full appraised value and rates are modest, the effective burden tends to be low for single home households, even in expensive neighborhoods.

Comprehensive real estate tax

The comprehensive real estate tax is layered on top for higher value holdings. The first 900 million won of combined appraised value is exempt, or 1.2 billion won for single home households. Above that threshold, progressive rates from 0.5 percent up to 5 percent apply, with higher rates for owners with many homes. Credits and deductions vary with circumstances, but the broad design is to focus the national levy on larger portfolios and luxury properties.

Finance Minister Koo Yoon cheol has used a simple illustration to show what a tougher holding regime might look like if Korea moved closer to international norms. He compared a hypothetical 1 percent annual tax on property value, a rate often cited in parts of the United States, with Korea’s current effective burden. He said that such a rate would translate into roughly 50 million won per year on a 5 billion won home, a sum that would challenge many households if it landed on top of mortgage payments and other costs.

Low holding taxes, high transaction taxes

Korea’s ownership burden is low compared with peers, both in top line rates and in effective taxes after exemptions and the partial valuation base. The flip side is heavy transaction taxation, especially capital gains taxes that rise sharply for owners with many homes or for sales inside regulatory zones. When selling triggers large tax bills, owners delay listings. The market grows sticky, and scarcity pushes prices higher in sought after districts.

This stickiness can be seen in the treatment of temporary two home situations. Home buyers who move and lease out their old apartment often aim to sell within three years to preserve single home tax treatment. New designations that require buyers to live in the property and restrictions on inheriting tenants make those sales harder. When deferrals on heavy taxation for owners with many homes expire next May, surcharges can add 20 percentage points to the base capital gains tax rate. Including local add ons, the effective rate can reach very high levels for certain sales in adjustment target zones. That prospect pushes some owners toward gifting strategies or simply waiting, which keeps turnover low.

Analysts disagree on how low Korea’s holding taxes truly are. One research group estimates the effective holding tax rate at about 0.15 percent of property value, while the OECD average is closer to a third of a percent. A public finance institute points out that, as a share of national tax revenue and gross domestic product, Korea’s property taxes do not look especially small. The two views reflect different lenses. One compares the tax burden paid by a typical owner. The other looks at how much the entire system raises, which in Korea can be large because real estate accounts for a very large share of household wealth.

What officials are saying

President Lee Jae Myung has pressed for stronger action against speculative demand and left the door open to tax changes alongside supply plans. Finance Minister Koo Yoon cheol has become the public face of the argument that the current mix of low holding taxes and high capital gains levies has frozen the market.

Speaking about international comparisons and the potential stress on households if Korea adopted a much higher annual levy, the finance minister said:

“If we were to apply a 1 percent property tax rate like in the United States, the owner of a 5 billion won home would have to pay about 50 million won each year. If half of one’s annual income goes to taxes, keeping such a home becomes unsustainable.”

Kim Yong beom, the presidential policy chief, has argued that credible housing policy requires both tax and supply reforms, and that revisiting ownership taxes should not be off limits.

“It is wrong to say we cannot touch the tax code. A credible housing policy must include both tax and supply reforms.”

Officials say any reform will go through careful review to avoid unexpected shocks. The finance ministry has also described the goal as rationalizing the system, which includes examining whether to rebalance between holding and transaction taxes and how to stage any changes.

Political stakes before local elections

Politics loom over the timing. Tax increases on homeowners are sensitive, especially in a period of higher borrowing costs that already strain households with mortgages. Party strategists caution that a visible move to raise ownership taxes could alienate middle class homeowners in key districts. That reaction risk is one reason many observers expect deliberation to stretch past the June elections, even if the policy direction becomes clearer sooner.

The ruling Democratic Party has emphasized near term supply. Party leaders have outlined plans to speed redevelopment and reconstruction, extend public housing timelines and streamline approvals. They have stated that changes to property tax rules are not on the agenda for now. The opposition People Power Party has long argued for greater private sector involvement in supply and for easing regulations, along with relief from heavy transaction taxes that hit owners with many homes in designated zones.

Meanwhile, the web of regulatory designations created to restrain demand remains in force. Adjustment target zones and land transaction permit zones impose residency and transaction conditions that can complicate sales. Some owners caught in temporary two home situations face a squeeze. They cannot easily sell because buyers must occupy the home. If leases are extended under tenant renewal rights, the sale window can close until the deferral on heavy taxation ends, at which point taxes jump. That exact situation is already showing up in case reports from agents across the city.

What a tax reset might look like

Reform ideas fall into two broad camps. One camp proposes lowering transaction taxes while modestly raising holding taxes, on the theory that this would coax more listings and let homes circulate. The other camp warns of rent inflation if holding costs rise too quickly and then get passed on to tenants. Both concerns are real, and the policy outcome will depend on design details.

A balanced package could include the following elements:

• Moderate increases in holding taxes for high value properties, paired with relief for cash poor, asset rich households such as retirees
• Targeted cuts to capital gains surcharges that block normal sales, especially for single home households and temporary two home cases
• Transparent and frequent valuation updates so tax bases track reality without sudden jumps
• Credits or deferrals for seniors and long term residents to reduce distress sales
• Phased implementation to allow households and markets to adjust

Experience in OECD countries shows that property tax reform is politically difficult. Homeowners feel annual levies more acutely than one time taxes at sale. Reforms tend to work best when valuation rules are clear, bills are predictable and revenue is tied to visible local services. Communication and phasing are critical to gain public acceptance.

Will higher holding taxes lift rents

Economists disagree on the rent effect. In markets with tight supply, landlords often pass some costs to tenants over time. The risk is sharper in Seoul, where the jeonse system is widely used. In jeonse, tenants provide a large deposit for the use of a home rather than paying monthly rent. Landlords invest the deposit, and some have used that capital to finance more purchases. If ownership costs rise quickly, landlords could seek higher deposits or shift to monthly rent to maintain returns.

Several design choices can limit rent pressure. Policymakers can phase in higher holding costs, protect single home landlords, and cut transaction taxes at the same time to bring more properties to market. Strong tenant rights, including limits on rent increases during renewals and clear rules on deposit returns, also matter. Korea already grants tenants the right to renew for up to two additional years, and many localities cap rent increases during renewal. Those protections help, but they do not remove the need to calibrate holding tax changes carefully.

The central bank and markets are watching

The Bank of Korea has signaled caution about feeding a real estate rebound. Governor Rhee Chang yong has said the housing problem is complex and that demand concentrated in certain school districts and neighborhoods cannot be solved with one tool. He also called for a stronger role for the central bank in macroprudential policy around household debt and housing.

Rhee linked the housing issue to education and migration patterns within the capital region. Even a large building push may not tame prices if flows of people into popular districts continue. The message aligns with the government’s view that supply, demand controls and taxation must work together, and that tax fairness across assets should be part of the review.

Financial markets have responded to the latest property measures. Shorter maturity government bonds, which are sensitive to policy expectations, have seen yields ease on bets that cooling the housing market gives the central bank space to adjust rates without stoking a bubble. Investors are watching how tax and regulatory choices interact with the growth outlook and inflation.

What this means for homeowners and renters

The immediate takeaway is that policy direction is shifting, but the details and timing are still under review. Owners and tenants can prepare by understanding the current rules and how a rebalanced tax code could change incentives. A few practical points follow.

• Single home households below the comprehensive real estate tax threshold are unlikely to see large changes in the near term if reform targets high value assets first
• Owners with many homes in adjustment target zones face a narrower set of options the longer they wait to sell, given surcharges that return next May
• Temporary two home cases should review lease timelines and residency rules in land transaction permit zones to avoid losing favorable tax treatment by missing sale windows
• Landlords should stress test cash flow for potential increases in annual holding costs and consider how a shift from capital gains taxes to holding taxes could affect returns
• Tenants should monitor deposit terms and renewal rights, especially in neighborhoods where landlords could respond to higher costs by seeking larger deposits or shifting to monthly rent
