Every late November, Korean news mentions "comprehensive real estate tax bills." But didn't we already pay property tax in July? They're two entirely different taxes.
In one line — property tax applies to every owner (local tax), while comprehensive real estate tax applies only above certain thresholds (national tax). The latter is layered on top of property tax.
Property tax vs. comprehensive real estate tax
| Item | Property tax / comprehensive tax |
| Type | Local / national |
| Who pays | All owners / owners above the deduction |
| Assessment date | June 1 / June 1 (same) |
| Payment | July and September / December 1–15 |
| Calculation unit | Per property / per person, nationwide total |
| Surtax | Local education tax / 20% rural development tax |
The critical difference is "per person, nationwide." Property tax is billed property by property; the comprehensive tax adds up the published prices of every home you own across Korea.
Am I liable? The basic deduction
| Single-home household | ₩1.2B |
| Others (multi-home) | ₩900M |
| Aggregate land | ₩500M |
| Separately aggregated land | ₩8B |
This is the fork. A single-home owner with a ₩1.2B published price pays zero. A multi-home owner whose homes total ₩1.2B has a ₩900M deduction and pays tax on ₩300M. Same total, different result.
Also note the base is the published price, not market price — typically 60–70% of market. In practice, single-home owners enter the net around a ₩1.7–1.8B market value.
How it's calculated
| ① Sum published prices | All your homes nationwide |
| ② − basic deduction | ₩1.2B single / ₩900M other |
| ③ × fair market ratio | Housing 60% (land 100%) |
| = tax base | Rates applied here |
| ④ − property tax already paid | Overlapping amount deducted |
| ⑤ − tax credits | Age and long-holding (single home) |
| ⑥ + rural development tax | 20% of the tax |
Step ④ matters: it prevents double taxation on the same value.
Credits for single-home owners
| Age credit | Rises by age band from 60 |
| Long-holding credit | Rises with years held, from 5 years |
| Combined cap | Up to 80% together |
An older owner in a long-held single home often sees the tax shrink to near nothing — which is why the "tax bomb on one home" worry frequently doesn't match reality.
Is joint ownership better?
| Sole ownership (single home) | ₩1.2B deduction + age and holding credits |
| Joint ownership (couple) | ₩900M each, ₩1.8B combined |
Joint ownership looks better on the headline deduction, but sole ownership can cut up to 80% through age and holding credits — so older, longer-held owners eventually favor sole treatment. Joint owners may therefore apply for single-home special treatment and be assessed the sole-ownership way, choosing each September whichever is better.
Payment and installments
- Billed by the tax office around late November — no filing required (self-filing is optional).
- Payment window: December 1–15.
- Installments available when the tax exceeds ₩2.5M.
- Exclusion filing in September removes qualifying rental and company housing from the total.
FAQ
Where do I find published prices?
On the official real estate price disclosure site, published annually with an objection window.
Does a rented-out home count?
Yes — liability follows ownership. Rental income is taxed separately (rental income tax).
What if I sell just before June 1?
The June 1 owner pays. Closing on May 31 shifts that year's bill to the buyer.
Are inherited homes included?
Special rules can exclude them from the count for a period. Check the requirements.
This tax is set by your total published prices, not your home's price tag. Track two calendars: property tax in July and September, comprehensive tax in December.
