What is the comprehensive real estate tax?

The Korean comprehensive real estate tax is a national tax assessed on June 1 each year when the published prices of your homes exceed a deduction limit. Single-home sole owners get a 1,200,000,000 KRW deduction; multi-home or other cases get 900,000,000. Tax base = (sum − deduction) × 60% fair-market ratio. Normal progressive rates run 0.5–2.7% across 7 brackets. If you own 3+ homes including in adjusted target areas, base over 1.2B KRW is taxed at heavier rates (0.5–5.0%). Single-home owners receive an age credit (20/30/40% at 60/65/70+) plus a tenure credit (20/40/50% at 5/10/15+ years), capped at 80% combined.

Frequently asked questions

When is the comprehensive tax due?
Self-assessment between December 1 and December 15 each year. The NTS sends bills in mid-November. File and pay through Hometax (hometax.go.kr). Installment (over 2.5M KRW) and credit-card payment are available.
How is joint ownership treated?
By default each owner files based on their share; enter only your share into this calculator. Married couples may opt into a single-home household election to combine for the 1.2B deduction and single-home credits, which can be more favorable depending on the case.
How does this differ from property tax?
Property tax is a local tax billed every July and September on all home owners; the comprehensive tax is a national tax billed in December only when holdings exceed the deduction limit. The property-tax double-counting credit is not modeled here, so the final amount may be lower in practice.
Are registered rental homes excluded?
Eligible long-term, public-support, and acquisition-rental units are excluded from comprehensive tax aggregation. This calculator does not handle the exclusion automatically — subtract those holdings before entering the sum.

Reference only. Covers residential comprehensive tax basics. The property-tax double-counting credit, the 20% rural surtax, exclusion of registered rentals, the joint-ownership single-home election, and the year-on-year cap are not modeled. Use the Hometax simulator or a tax accountant for the precise figure.
