Enter the total government-assessed value of houses you own, your house-count category, and the fair market value ratio to estimate the taxable base, calculated tax, the senior/long-term holding tax credit for single-house households, and the total tax due including the special rural development tax.
Enter the total assessed value to calculate the tax.
This is a simplified estimate only, based on Korea's Comprehensive Real Estate Tax Act housing rules as amended in 2023. It applies a deduction of ₩1.2 billion for single-house households under sole ownership (1세대1주택 단독명의) and ₩900 million otherwise, with progressive rates of 0.5-2.7% for 2 or fewer houses, and 0.5-1.0% up to a ₩1.2 billion base plus 2.0-5.0% above that for 3 or more houses. For single-house households, it applies the senior tax credit (20-40% for ages 60-70+) and long-term holding tax credit (20-50% for 5-15+ years held), combined up to a maximum of 80%. It does NOT account for the property tax credit (재산세액공제) for property tax already paid on the same base, the tax burden cap (세부담 상한) versus the prior year, houses excluded from aggregation (rental housing, etc.), or the special filing for jointly-owned single houses (부부 공동명의 1주택 특례) — so your actual liability may differ. The fair market value ratio (공정시장가액비율) is set annually by government policy, so check the current year's official rate before entering it. Confirm your exact tax liability via Hometax (홈택스) or a licensed tax professional. This is not legal or tax advice.
