What is the comprehensive real estate tax?
Comprehensive Real Estate Tax (Jongbuse) is a national tax imposed when the total official assessed price of homes you own exceeds a threshold as of June 1 each year. It is separate from property tax (local) and is filed and paid in December. As of 2026, single-name 1-household 1-home owners get a KRW 1.2B deduction; others (multi-home owners, joint-name 1-home, multi-home joint names) get KRW 900M. Above the threshold, general rates (0.5–2.7%) or heavy rates (0.5–5.0% for multi-home in regulated areas) apply. 1-household 1-home owners receive tax credits combining age (60+ : 20–40%) and holding period (5+ years: 20–50%), totaling up to 80%. Additional safeguards include a credit for double-counted property tax and a burden cap (150% YoY for general, 300% for multi-home). This calculator simulates a typical single-name case. Complex situations such as the joint-name 1-home special election, registered rental properties, corporate ownership, and aggregation exemptions are not reflected. The exact amount appears on the NTS notice in November.
When is this calculator useful?
Estimating total holding tax before buying
Estimate combined property + comprehensive tax for a new purchase. Check whether the official total crosses the KRW 900M or 1.2B threshold.
Single-name vs. joint-name comparison
Single-name 1-home owners get KRW 1.2B deduction + age/holding credits; joint-name can elect the special treatment. Compare both.
Impact of official price changes
Estimate the additional burden after the April price announcement. The burden cap (150%, 300% for multi-home) limits year-over-year increases.
Long-term holding credit effect
1-home owners with 5+ years of holding get up to 50% credit, plus age credit (60+), totaling up to 80%.

How to read the result
The result is composed of: • Total official price: sum of official prices of your homes. • Deduction: KRW 1.2B (single-name 1-home) or KRW 900M (others). • Taxable base: (total − deduction) × fair market value ratio (60–80%). • Assessed tax: taxable base × rate (0.5–2.7% general / 0.5–5.0% heavy). • Tax credits: age and holding credits for 1-home owners, up to 80%. • Final tax: assessed − credits − double-counted property tax credit. Special Tax for Rural Development (20% of final tax) is added separately. This calculator shows only the base.
Things to keep in mind
- This calculator targets typical single-name cases. Joint-name, multi-home, corporate ownership, and registered rental properties require separate calculation.
- Official prices are announced annually in April and typically run 60–80% of market value. Use the official price (not purchase price) for an accurate calculation.
- Multi-home owners (2+ homes) in regulated areas face heavy rates up to 5.0%. Policy changes are frequent — confirm the latest law.
- 1-home owner credits combine age (60+: 20%, 65+: 30%, 70+: 40%) and holding (5+ years: 20%, 10+: 40%, 15+: 50%) up to 80%.
- The burden cap (150% general, 300% multi-home) limits year-over-year increases. This calculator does not reflect the cap.
- Joint-name 1-home owners can elect the single-name special treatment in September each year (KRW 1.2B deduction + age/holding credits).
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.
- When is comprehensive tax due?
- Payment is December 1–15 each year. The NTS sends a notice in November, so you just pay — no separate filing required. Amounts of KRW 2.5M or more can be split (twice). Voluntary filing is also available.
- How is joint-name 1-home calculated?
- By default, each name gets a KRW 900M deduction (KRW 1.8B total), but joint-name 1-home owners can elect the single-name special treatment (KRW 1.2B deduction + age/holding credits). Which is better depends on holding period and age.
- How is property tax different from comprehensive tax?
- Property tax is a local tax on all real estate owners; comprehensive tax is a national tax only for owners exceeding the threshold (KRW 1.2B for 1-home, 900M otherwise). Both apply to owners as of June 1. Double-counted property tax is credited against comprehensive tax.
- Are registered rental homes exempt from comprehensive tax?
- Registered private rental homes meeting certain conditions can be excluded from comprehensive tax via the aggregation exemption. However, registration policy changed significantly after 2020 — verify with the NTS or a tax accountant.
