What is comprehensive real estate tax?
Comprehensive real estate tax is a national tax levied when an individual's total published price of owned houses exceeds a deduction threshold. After deducting the threshold, a fair market ratio (60%) is applied to get the tax base, then the rate table is applied.
Deductions and rate table (2026)
One-household one-house owners deduct 1.2B KRW; others (2 houses or fewer / 3+ houses) deduct 900M KRW. The remainder × 60% is the tax base. 3+ house owners face higher surcharge rates above a 1.2B tax base.
Surcharge for 3+ houses
Owners of 3 or more houses face higher rates (up to 5.0%) above a 1.2B KRW tax base compared to 2-or-fewer owners. This tool computes only the calculated tax from the fixed rate table; age/long-term holding credits and property tax overlap deductions are not included.
Surcharge rates from the third home, and the available credits
The comprehensive real estate tax uses different rate tables by number of homes. The table above covers two homes or fewer; from the third, upper bands rise sharply.
Rates from the third home
| Tax base | Rate | Progressive deduction |
|---|---|---|
| up to 300,000,000 KRW | 0.5% | — |
| 300,000,000 KRW – 600,000,000 KRW | 0.70% | 600,000 KRW |
| 600,000,000 KRW – 1,200,000,000 KRW | 1% | 2,400,000 KRW |
| 1,200,000,000 KRW – 2,500,000,000 KRW | 2% | 14,400,000 KRW |
| 2,500,000,000 KRW – 5,000,000,000 KRW | 3% | 39,400,000 KRW |
| over 5,000,000,000 KRW | 5% | 139,400,000 KRW |
The lower bands match the two-home table; the tables diverge from the middle bands upward.
Deduction and fair market value ratio
| Item | Value |
|---|---|
| Basic deduction | 900,000,000 KRW |
| Single-home deduction | 1,200,000,000 KRW |
| Fair market value ratio | 60% |
| Rural special tax | 20% |
Add the published prices of all homes owned, subtract the deduction, and multiply the remainder by the fair market value ratio. Below the deduction, no tax arises.
Credits for single-home owners
Beyond the larger deduction, single-home owners receive credits against the assessed tax. Two apply and they combine.
One is age-based, starting at 60 and rising with age. The other is holding-period based, starting at five years and increasing with duration.
A combined ceiling caps the total. The design relieves long-resident older owners, so identical homes can attract very different bills depending on the owner.
Adjusting for property tax already paid
Both taxes fall on the same home, so property tax already charged on the overlapping base is deducted from the comprehensive tax.
Because of this, adding the property tax bill directly to a comprehensive tax estimate overstates the burden. Use the adjusted figure.
A burden cap also applies, limiting the combined total to a multiple of the previous year's, so bills do not track sharp jumps in published prices.
Assessment date and payment
The assessment date is 1 June, as for property tax. Buying just before it means bearing the whole year's holding taxes, so a balance date from 2 June suits the buyer.
The National Tax Service issues assessments in late November for payment between 1 and 15 December. Self-assessment is also available where the notice does not match the facts.
Larger amounts may be paid in instalments, and qualifying older or long-holding single-home owners can defer payment until the home is sold or inherited.
