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%.
Comprehensive tax brackets
Normal rates (2 homes or fewer)
| Tax base | Rate |
|---|---|
| Base ≤ 300M | 0.5% |
| Base 300–600M | 0.7% |
| Base 600M–1.2B | 1.0% |
| Base 1.2–2.5B | 1.3% |
| Base 2.5–5.0B | 1.5% |
| Base 5.0–9.4B | 2.0% |
| Base > 9.4B | 2.7% |
Heavy rates (3+ homes incl. adjusted area)
| Tax base | Rate |
|---|---|
| Base ≤ 300M | 0.5% |
| Base 300–600M | 0.7% |
| Base 600M–1.2B | 1.0% |
| Base 1.2–2.5B | 2.0% |
| Base 2.5–5.0B | 3.0% |
| Base 5.0–9.4B | 4.0% |
| Base > 9.4B | 5.0% |
Heavy rates apply only when 3+ homes are held including in adjusted target areas AND the tax base exceeds 1.2B KRW.
Single-home credits (sole owner)
- Age: 60+ 20% / 65+ 30% / 70+ 40%
- Tenure: 5+ yrs 20% / 10+ yrs 40% / 15+ yrs 50%
- Combined credit capped at 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.
Worked examples
1-household 1-home, KRW 1.6B published price, age 65-69, held 12 years
Assume: published price KRW 1.6B, 1-household 1-home owner, age 65-69, held 12 years. ① KRW 1.2B deduction applied → base before ratio = 1.6B − 1.2B = KRW 400M ② 60% fair market ratio → taxable base KRW 240M ③ 0.5% rate (progressive deduction 0) → computed tax KRW 1.2M ④ Age credit 30% + holding credit (10-14yr) 40% = combined 70% tax credit → credit amount KRW 840K ⑤ Final tax = 1.2M − 840K = KRW 360K Long-term 1-home owners see a much lighter burden thanks to the age/holding tax credit (note: the credit must be separately applied for via Hometax).
Multi-home owner (3+ homes, regulated area), KRW 3B published price
Assume: published price KRW 3B, 3+ homes owned, in a regulated area (heavy-rate eligible). ① Multi-home deduction KRW 900M applied → base before ratio = 3B − 900M = KRW 2.1B ② 60% fair market ratio → taxable base KRW 1.26B (exceeds the KRW 1.2B heavy-rate threshold, so the heavy bracket table applies) ③ 2% rate (progressive deduction KRW 14.4M) → computed tax KRW 10.8M ④ Multi-home owners don't qualify for the 1-home age/holding credit, so the final tax stays at KRW 10.8M Even with the same published price, 1-home vs. multi-home owners face very different deduction caps (KRW 1.2B vs. 900M) and rate tables (normal vs. heavy), producing a large tax gap.
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 comprehensive property tax due?
- Payment is due between December 1–15 each year. The NTS sends a notice in mid-November, and you can also check and self-file via Hometax (hometax.go.kr). Amounts over KRW 2.5M can be paid in two installments.
- How is joint-name 1-home ownership calculated?
- By default, each spouse files separately using their own ownership share, each getting the KRW 900M deduction (KRW 1.8B combined) — enter only your own share's published price. Alternatively, applying for the '1-household 1-home joint-ownership special election' lets the couple use the combined KRW 1.2B deduction plus age/holding-period tax credits, which can be more favorable depending on the situation. Compare both on Hometax before electing.
- How is this different from property tax?
- Property tax is a local tax paid by all homeowners every July and September. Comprehensive property tax is a national tax paid only by those whose total published price exceeds the threshold (KRW 1.2B for 1-household 1-home, KRW 900M otherwise), due in December. In practice, a portion already paid as property tax is credited against comprehensive tax to avoid double taxation — this calculator simplifies by not modeling that credit.
- Are registered rental homes excluded from comprehensive tax?
- Private rental housing (long-term general, publicly-supported purchase-rental, etc.) can be excluded from aggregation if it meets the requirements. Since rental registration rules have changed repeatedly since 2020, this calculator does not model the exclusion — if you own a registered rental home, exclude its published price from your input.
- What does this calculator not account for?
- It does not reflect the property-tax double-taxation credit, the 20% special rural tax, the year-over-year tax burden cap, aggregation exclusions, or whether you've elected the joint-ownership special treatment. For an exact figure, use the Hometax comprehensive tax simulator or consult a tax accountant.
- Is the 1-household 1-home tax credit applied automatically?
- No. You must apply separately via Hometax between September 16–30 each year (if you meet the age/holding-period requirements). Without applying, you're billed the full calculated tax with no credit.
- Where do I check the published price of my home?
- On MOLIT's Real Estate Price Notification site (realtyprice.kr). Apartment published prices are announced every year in late April, and this figure is the basis for both comprehensive property tax and property tax.
- I didn't receive a comprehensive tax notice — do I still need to file?
- Payment obligation remains even without a notice. Check Hometax directly and self-file/pay by December 15 to avoid a non-filing penalty.
