Korea Property Holding Tax Calculator (Property Tax & Comprehensive Real Estate Tax)

Homeowners pay property tax (local tax) every year, and when the total announced value of all homes held by an individual exceeds a certain threshold, a Comprehensive Real Estate Holding Tax (national tax) is also levied. Enter the announced value below to estimate both taxes.

The following items are not reflected in this calculator or are approximations. The actual assessed tax may be lower than this estimate.

Elderly / long-term holding tax credit — reflected only when "Number of Homes" is set to "1 home" and age and holding period are entered. The approximation adds: 20% (age 60+), 30% (age 65+), 40% (age 70+) for the elderly credit, and 20% (5+ years), 40% (10+ years), 50% (15+ years) for the long-term holding credit, up to a combined maximum of 80%. Detailed eligibility conditions such as household composition are not verified.
Property tax credit (double taxation adjustment) — reflected approximately only when the same home was calculated in Section 1 above and the "Calculate Comprehensive Real Estate Holding Tax below" button was used to carry the value over (the relevant row will appear in the table above). If the value was entered manually, or if multiple homes were aggregated, it is not reflected — because the actual statutory calculation involves a multi-step apportionment per property that is difficult to reproduce accurately for multi-home cases.
Tax burden ceiling — limits sharp year-on-year tax increases. (This calculator does not reflect it. For reference, the comprehensive real estate tax ceiling of 150% has been confirmed, but the property tax ceiling for housing is unclear following recent amendments and could not be definitively established.)

In particular, long-term owners of a single household home may find a very large difference between this estimate and the actual assessed amount.

This calculation is a simplified estimate. Actual property tax and comprehensive real estate tax amounts vary based on enforcement ordinances, various tax credits, tax burden ceilings, and other factors. The fair market value ratio, tax rates, and deduction amounts are subject to change through legislative amendments. For the actual tax amount, refer to the guidance from the relevant local government (property tax) and the National Tax Service's Hometax system (comprehensive real estate tax).

Frequently Asked Questions

What is the announced value and where can I check it?

The announced value (공시가격) is the reference price the government surveys, calculates, and publishes annually for each property. It serves as the basis for property tax and comprehensive real estate tax. It differs from the actual market transaction price and is typically lower than market value. You can look up the announced value of your property by address on the Real Estate Announced Price Notification System (부동산공시가격 알리미).

What is the difference between property tax and comprehensive real estate tax?

Property tax is a local tax levied by the local government on anyone who owns real estate, assessed annually. For housing, it is typically billed in two halves — in July and September. Comprehensive real estate tax is a national tax levied on the portion of an individual's total housing announced value that exceeds the deduction threshold (₩1.2 billion for a one-household, one-home owner; ₩900 million otherwise). It is assessed annually in December by the National Tax Service. In short, property tax applies to all real estate owners, while comprehensive real estate tax is an additional levy on those holding high-value or multiple properties.

Why might this calculator's result differ from my actual tax bill?

The comprehensive real estate tax property tax credit (double taxation adjustment) and elderly / long-term holding credit are reflected approximately when conditions are met (one-household one-home, relevant data entered), but the tax burden ceiling is not reflected. This calculator also covers only the basic calculation flow using rate schedules and the fair market value ratio, without verifying detailed eligibility conditions such as household member count. The fair market value ratio, tax rates, and deduction amounts can change annually through amendments to enforcement decrees — always confirm the exact amount through your local government or Hometax notice.

What is the one-household, one-home special treatment?

This is a scheme that reduces the tax burden for a household owning only one home in Korea. For property tax, a lower fair market value ratio (43–45%) applies regardless of the property's value, and for properties with a standard market value of ₩900 million or less, a further reduced special tax rate (0.05–0.35%) also applies (the portion above ₩900 million is calculated at the standard rate). For comprehensive real estate tax, the deduction threshold rises from ₩900 million to ₩1.2 billion, and the elderly / long-term holding credit is also available only in this case.
