Origins: who built it and why
In the early 2000s apartment prices in Seoul's Gangnam district surged. The Roh Moo-hyun government floated a separate national tax on high-value property in its October 2003 housing package, and the Comprehensive Real Estate Holding Tax Act passed in January 2005. The idea was that local property tax alone was too light on owners of several expensive homes, that a holding tax would cool speculation, and that the revenue could narrow fiscal gaps between regions: every won collected is passed to local governments as a real-estate grant.
The intellectual roots go back to Henry George (1879), who argued that rising land values are created by society, not owners, and should be taxed. Jongbuse is that land-value idea filtered through Korean anti-speculation politics.
The court ruling and later reforms
A 2005 package lowered the threshold from 900 million to 600 million won and added up property held by everyone in a household. Married couples protested that marriage itself raised their tax, and on November 13, 2008 the Constitutional Court agreed, striking down household aggregation (Constitutional Court, 2008). The tax has been assessed per person ever since. Rates swung with politics: multi-home owners faced up to 6% in 2021, then reforms in 2022–2023 raised the basic deduction to 900 million won (1.2 billion for single-home households) and cut rates to 0.5–2.7%, with up to 5% for owners of three or more homes above a 1.2 billion won tax base (NTS, n.d.-a).
How the bill is calculated
- Add up the official assessed values of all homes in your name.
- Subtract 900 million won (1.2 billion for a single-home household).
- Multiply by the 60% fair-market-value ratio to get the tax base.
- Apply the progressive rate and subtract the bracket deduction.
- Subtract local property tax already paid on the same slice, plus age and long-holding credits for single-home owners (up to 80% combined).
- Cap the increase at 150% of last year's combined holding tax (NTS, n.d.-b).
| Tax base | Up to 2 homes | 3+ homes |
|---|---|---|
| ≤ KRW 300m | 0.5% | 0.5% |
| ≤ 600m | 0.7% | 0.7% |
| ≤ 1.2bn | 1.0% | 1.0% |
| ≤ 2.5bn | 1.3% | 2.0% |
| ≤ 5bn | 1.5% | 3.0% |
| ≤ 9.4bn | 2.0% | 4.0% |
| > 9.4bn | 2.7% | 5.0% |
Example: a single-home household with an official value of 1.5 billion won has a base of (1.5bn − 1.2bn) × 60% = 180 million won, or roughly 900,000 won at 0.5% before credits. A 20% rural development surtax is added, and bills above 2.5 million won can be split over six months.
What economists argue
Tiebout (1956) and Hamilton (1975) frame property tax as a price for local services that residents shop for; Zodrow (2001) summarizes the rival view that it is ultimately a tax on all capital. Who bears it is a question of tax incidence. Oates (1969) showed that taxes are capitalized into home prices, so a big hike can weigh on values, though supply, interest rates and lending rules such as loan-to-value limits matter too. To see the full picture, pair it with capital gains tax on sale and gift tax on transfers.
Common myths and a checklist
- It uses the government's assessed value, not market price; a home selling for 2 billion may still owe nothing.
- Joint ownership gives each spouse a 900 million won deduction (1.8 billion total); couples may choose whichever regime is cheaper.
- A temporary second home is ignored if the old one is sold within three years.
- Ownership on June 1 decides who pays that year.
Foreign owners of Korean property are subject to the same rules. Remember the gap between marginal and effective rates: even in a top bracket, the effective burden is usually far lower.
FAQ
- If my home is worth 2 billion won, do I owe jongbuse?
- Not necessarily. Thresholds use the official assessed value, which is usually well below market price.
- Where does the money go?
- All revenue is distributed to local governments as a real-estate grant.
