South Korea collects property-related taxes equal to 3.0% of GDP, roughly double the OECD average of 1.6%. Yet the composition of that revenue is almost the mirror image of what most advanced economies do. Across the OECD, recurrent holding taxes (annual property taxes) account for 56% of total property tax revenue; in Korea, they represent just 29.4%. Transaction taxes — stamp duties, acquisition levies, and capital gains surcharges — make up 50.4% of Korea’s property tax take, compared with an OECD average of around 20%. This structural imbalance is the central finding of the OECD’s 2026 Economic Survey of Korea, which urges Seoul to shift the tax burden from transactions to recurrent holding taxes.

This article compares the residential property tax systems of four major economies — South Korea, the United States, the United Kingdom, and Japan — across assessment bases, statutory rates, reliefs, and surcharges. It draws on official OECD data, national tax authority publications, and independent research to answer three questions: How much do homeowners actually pay in each country? Why does the structure of property taxation matter as much as the level? And what are the household-level consequences of Korea’s unusual dual-tax design?

OECD Data: Where Does Korea Stand?

The OECD Revenue Statistics classify property taxes into three categories: recurrent taxes on immovable property (Category 4100, the annual “holding tax”), non-recurrent taxes on immovable property (Category 4200, transaction taxes such as stamp duties and registration fees), and taxes on capital gains (Category 4300). Across all 38 OECD members, total property tax revenue averages 1.6% of GDP and 5.3% of total tax revenue.

Effective property tax rates across major economies (OECD data)

The variation among countries is enormous. The United Kingdom leads with recurrent property taxes of 3.1% of GDP, followed by the United States at 2.7%, Canada at 2.5%, and Japan at 1.9%. At the other end, Austria levies just 0.2% of GDP, Switzerland 0.6%, and Germany 0.5%. Korea’s recurrent property tax revenue sits at roughly 0.9–1.0% of GDP — close to the OECD average of 0.9% and well below the Anglo-Saxon leaders.

Where Korea diverges sharply is in transaction taxes. At 50.4% of total property tax revenue, Korea’s reliance on transaction levies is 2.5 times the OECD norm. The Seoul Economic Daily reported that the OECD described Korea’s overall property tax burden as “double the OECD average” while noting that the holding-tax component alone is not unusually high. The policy implication is clear: the problem is not the total amount Korea collects, but where it collects it.

South Korea: The World’s Only Dual Holding-Tax System

Korea is virtually alone among advanced economies in splitting its annual property tax into two separate levies. The Property Tax (재산세) is a local tax applied to all residential properties, land, and buildings at progressive rates of 0.1–0.4%. The Comprehensive Real Estate Holding Tax (종합부동산세, or “jongbu-se”) is a national surtax that applies only to owners whose combined assessed property values exceed a threshold — 1.2 billion won for a single-home owner as of 2026.

The assessment base is itself discounted twice. The official assessed value (공시가격) reflects approximately 69% of market value under the 2026 “realization rate” freeze. A further “fair market value ratio” of 60% is applied before the tax rate is calculated. The net effect is that the taxable base for a home worth 1 billion won on the open market is roughly 414 million won — just 41.4% of market value.

A National Assembly Budget Office (NABO) comparative study of nine countries and ten cities confirmed that Korea’s dual structure — a local property tax plus a national holding surtax — is unique among the economies surveyed. The United States, United Kingdom, Japan, Germany, France, Canada, Australia, and Sweden all operate a single recurrent property tax. The NABO report noted that the dual system reduces transparency and makes it difficult for taxpayers to understand their true effective burden.

For multi-home owners, Korea adds further layers: acquisition tax surcharges of up to 12%, a comprehensive holding tax rate of up to 5.0%, and capital gains tax rates reaching 75%. No other OECD country combines all three surcharges at these levels.

United States: Local Finance Built on Property Tax

The American property tax is the financial backbone of local government. There is no federal property tax; instead, counties, cities, school districts, and special-purpose authorities each levy their own rates on assessed property values. According to the Tax Foundation’s 2026 state-by-state data, effective property tax rates range from 0.27% in Hawaii to 2.23% in New Jersey — an eightfold spread. The national average effective rate in 2025 was 0.9%, up from 0.86% in 2024 and the highest since 2020.

Unlike Korea, the assessment base in most US jurisdictions is tied directly to market value, with no secondary discount ratio. Most states offer a Homestead Exemption that reduces the taxable value of a primary residence by a fixed amount — for example, Texas provides up to $100,000 in assessed-value relief for owner-occupied homes. The median annual property tax bill nationwide was approximately $3,800 in 2025, and average bills rose roughly 3% year-over-year, according to Realtor.com analysis.

Property taxes fund roughly 30–40% of local government revenue and are the primary source of public school funding in most states. This creates a visible feedback loop: communities with higher property tax rates often have better-funded schools, which in turn supports property values. The trade-off is regressivity — lower-income homeowners in high-tax jurisdictions can face disproportionate burdens relative to their income.

United Kingdom: Council Tax, Stamp Duty, and the 2026 Reform Debate

The UK taxes residential property at two distinct points: annually through Council Tax (a local levy) and at purchase through Stamp Duty Land Tax (SDLT). Council Tax, introduced in 1993, assigns every dwelling to one of eight valuation bands (A through H in England) based on 1991 property values. Each band carries a fixed annual charge set by the local authority. The average Band D charge in England for 2025/26 is approximately £2,171 per year.

SDLT is a progressive transaction tax. Since April 2025, the nil-rate threshold reverted to £125,000. Rates rise from 2% on the portion between £125,001 and £250,000, to 5% up to £925,000, and 10–12% above that. Purchasers of additional properties (second homes, buy-to-let) pay a 3-percentage-point surcharge on top of standard rates.

The UK system is in active flux. In August 2025, Chancellor Rachel Reeves signalled that the Treasury was exploring a replacement of SDLT with an Annual Property Charge — effectively converting a one-time transaction tax into a recurring holding tax. The Autumn Budget 2025 introduced a “mansion tax” on properties valued above £2 million, to be collected as a Council Tax supplement starting in 2026. These reforms align with the OECD’s long-standing recommendation to shift the tax mix from transactions to recurrent holding levies.

Japan: A Transparent 1.7% Combined Rate

Japan’s residential holding tax consists of two municipal levies: the Fixed Asset Tax (固定資産税) at 1.4% and the City Planning Tax (都市計画税) at 0.3%, for a combined statutory rate of 1.7%. Both are assessed by municipal governments (or, in Tokyo’s 23 special wards, by the metropolitan government). The Tokyo Metropolitan Tax Bureau confirms that the 2026 (Reiwa 8) assessment notices were dispatched on June 1, with payment in four instalments (June, September, December, February).

The assessment base is the government-published land value (公示地価), reviewed every three years, which typically represents about 70% of market value. A critical relief applies to residential land: plots of 200 square metres or less receive a one-sixth reduction in the taxable base, while larger plots receive a one-third reduction. Newly constructed homes receive a 50% reduction in the Fixed Asset Tax for three years (five years for condominiums).

Japan’s total recurrent property tax revenue is approximately 1.9% of GDP — more than double the OECD average and among the highest in the developed world. The Fixed Asset Tax alone accounts for roughly 40% of municipal tax revenue, making it the single most important source of local finance.

Why the Structure Matters: The Lock-In Effect and Labour Mobility

The OECD’s repeated calls for Korea to reduce transaction taxes and raise holding taxes rest on a well-established economic mechanism. Transaction taxes act as a one-time cost on every property sale, creating a “lock-in effect” that discourages households from moving. In Korea, the combined cost of acquisition tax (1–3%, up to 12% for multi-home owners) and capital gains tax (6–45%, up to 75% with surcharges) can reach 10–20% of a property’s value for a typical sale. This friction reduces residential mobility, which in turn impairs labour market efficiency: workers who cannot afford to relocate for better jobs remain in lower-productivity positions.

The OECD-recommended shift from transaction taxes to holding taxes

Recurrent holding taxes, by contrast, impose an annual cost on the act of owning property. This raises the opportunity cost of holding vacant or underutilised housing, encouraging more efficient allocation of the housing stock. Because the tax base is property value, revenue rises automatically during price booms, providing a built-in fiscal stabiliser. The OECD’s 2026 Korea survey explicitly states that “a revenue-neutral shift that reduces the proportion of transaction taxes and increases that of holding taxes will support residential mobility and improve labour market efficiency.”

The political economy, however, is challenging. Every country that has attempted to shift the balance has encountered resistance from incumbent homeowners who benefit from the status quo. The UK’s Council Tax has not been comprehensively reformed since 1993 precisely because any re-banding creates visible winners and losers. Korea’s experience in 2021 — when aggressive assessment increases and holding-tax hikes triggered a political backlash, followed by partial reversals — illustrates the same dynamic.

Household Impact: A Cross-Country Comparison for a $750,000 Home

To make the comparison concrete, consider a single-home household owning a property worth approximately 1 billion won (roughly $750,000 or £550,000).

In Korea, the assessed value is about 690 million won (69% realization rate), and the taxable base after the 60% fair-market ratio is roughly 414 million won. The annual Property Tax comes to approximately 1.3–1.5 million won. The Comprehensive Holding Tax threshold for a single-home owner is 1.2 billion won, so no surtax applies. The total annual holding tax is roughly 1.3–1.5 million won — an effective rate of 0.13–0.15% of market value.

In the United States, applying the national average effective rate of 0.9% to a $750,000 home yields an annual property tax of approximately $6,750 (about 9.3 million won). In New Jersey (2.23%), the bill would reach roughly $16,725; in Hawaii (0.27%), just $2,025.

In the United Kingdom, Council Tax is band-based rather than ad valorem. A property worth £550,000 falls into Band H, the highest band, where the annual charge is approximately three times the Band D average — roughly £6,500 (about 11.4 million won). SDLT is a one-time cost at purchase, not an annual burden.

In Japan, the assessment base for a ¥110 million property is approximately ¥77 million (70% of market value). After the one-sixth residential land reduction and building depreciation, the combined Fixed Asset Tax and City Planning Tax typically ranges from ¥800,000 to ¥1.2 million (approximately 7.2–10.8 million won), an effective rate of 0.7–1.0%.

The comparison reveals a striking pattern: Korea’s effective holding-tax rate (0.13–0.15%) is one-fifth to one-seventh of the rates in the US, UK, and Japan. Yet Korea’s total property tax revenue as a share of GDP is double the OECD average. The difference is entirely attributable to transaction taxes — the costs that fall on households when they buy, sell, or transfer property rather than when they hold it.

Uncertainties and Limitations

Several caveats apply to this cross-country comparison. First, the definition of “property tax” varies. The UK’s Council Tax is a fixed-charge system based on 1991 valuations, making direct comparison with ad valorem systems misleading. US property taxes bundle multiple overlapping jurisdictions, while Korea’s figures include only the Property Tax and Comprehensive Holding Tax.

Key considerations for property tax reform

Second, assessment methodologies differ substantially. Korea’s double discount (69% realization rate × 60% fair-market ratio) means the statutory rate of 0.1–0.4% overstates the effective burden. Japan’s assessment at 70% of market value requires a similar adjustment. Nominal rate comparisons without these adjustments are misleading.

Third, all four countries are in various stages of tax reform. The UK is actively considering replacing SDLT with an annual charge and has introduced a mansion tax. Korea’s realization rate freeze and Comprehensive Holding Tax thresholds remain politically contested. The OECD’s 2026 recommendations may or may not translate into legislation.

Fourth, this analysis focuses on single-home owner-occupiers. Multi-property owners, corporations, and registered rental businesses face entirely different rate schedules, surcharges, and exemptions that vary too widely for simple comparison.

Fifth, exchange rate fluctuations affect cross-country comparisons. This article uses approximate rates of 1,380 won per dollar, 1,750 won per pound, and 9.1 won per yen as of July 2026. Shifts in these rates can materially alter the perceived burden.
