Property tax from the published price
Housing property tax starts from published price × fair-value ratio = tax base, then applies the housing rate.
For 2026 the fair-value ratio is 60% in general (43–45% under the 1-home special), and standard rates run 0.1% to 0.4%. The 1-home special (published ≤900M KRW) is 0.05%p lower. This tool shows the base tax plus 20% local education tax only — the real bill also adds an urban-area levy (0.14% of the base) and a regional-resource tax. See the acquisition tax calculator.
