Korea's property tax rewrite — living in the home is worth 500 million won
The 2026 tax reform proposal in South Korea shifts the comprehensive real estate holding tax from a house-count basis to a value-and-residency basis, setting the single-home deduction at 1.4 billion won for owner-occupiers and 900 million won for non-residents, effective 2027
The three lines
- Deduction: 1.4bn won if you live in it (up from 1.2bn), 900m won if you don't — a 500m won gap on the same single home
- The axis moves from 'how many do you own' to 'how much is it worth and do you use it'
- Holding tax changes take effect in 2027, capital-gains long-residence relief in 2028 — still a government bill awaiting the National Assembly
Key questions
- What is Korea's comprehensive real estate tax
- A national holding tax levied annually on owners whose combined assessed property value exceeds a threshold, on top of the local property tax. It has long been one of the most politically contested taxes in Korea because it targets high-value holdings and has swung with each administration. The threshold subtraction is the 'basic deduction' at the center of this reform.
- Why does residency change the deduction
- Because the reform replaces house-count as the organizing principle. Under the current design, the number of homes owned drove the burden, which produced cases where one very expensive home was taxed more lightly than several cheap ones. The proposal raises the deduction for homes the owner actually lives in (1.2bn to 1.4bn won) and cuts it for those they do not (to 900m won).
- When does it take effect
- The holding-tax changes are proposed for 2027 and the capital-gains long-residence deduction for 2028. Both remain a government bill. Korean tax law requires passage through the National Assembly, and the final text differing from the announcement is not unusual.
- What happens to owners of multiple homes
- The proposal moves through an interim step in 2027 to applying a single rate table to single-home and multi-home owners alike from 2028. Today multi-home owners face a separate, steeper schedule. Removing that distinction means the progression is driven by value rather than count — lighter for many cheap homes, heavier for one expensive home left empty.
For most of two decades Korean property taxation rested on one question: how many homes do you own? The 2026 tax reform bill replaces it with a different one: how much is it worth, and do you actually live in it?
The government published the bill in early August, covering eleven tax statutes including ten domestic taxes and the customs act. The property provisions are the largest change, and the split in the comprehensive real estate tax deduction is the center of it.
This reference sets out what changes, when, and what is still undecided.
1. The deduction splits in two
| Category | Current | Proposed |
|---|---|---|
| Single home, owner-occupied | 1.2bn won | 1.4bn won |
| Single home, not occupied | 1.2bn won | 900m won |
| Organizing basis | Number of homes | Value + residency |
The basic deduction is subtracted from the combined assessed value of a taxpayer's holdings before the tax applies. A larger deduction pushes the whole liability downward.
The design is blunt: live there and get 200m won more; don't and lose 300m won. The same single home now carries deductions 500 million won apart. For properties assessed between the two figures, whether the owner occupies it decides whether the tax applies at all.
One clarification that matters. The assessed value here is the government-published price, not the market price, and it is typically set below market. A 1.4bn won deduction therefore covers homes worth more than 1.4bn won on the open market. Anyone checking their own position should look up the assessed value, not the listing price.
2. The 2027 and 2028 sequence
| Year | What changes |
|---|---|
| 2027 | Holding-tax reform takes effect — occupied/unoccupied deduction split |
| 2027 | Interim step toward a unified rate table |
| 2028 | Single rate table applied to single-home and multi-home owners alike |
| 2028 | Capital-gains long-residence deduction reform takes effect |
Rate-table unification is the second axis. Today multi-home owners face a separate, steeper schedule. The proposal removes that distinction and leaves progression to run on value alone.
The direction that produces is clear enough on arithmetic: owners of several inexpensive homes see lighter burdens, and owners of one expensive home they do not live in see heavier ones. Notably, occupancy alone does not guarantee relief — one outlet worked through a case in which an owner-occupier of a high-value Seoul apartment pays roughly 11 million won more per year even with assessed values unchanged, because rate and fair-market-ratio changes outweigh the larger deduction.
On the capital-gains side, weight shifts from long holding to long residence, with a long-residence deduction reaching 80% at ten years of actual occupancy under discussion. Same direction as the holding tax: credit for using the home, not merely owning it.
3. Beyond property
| Measure | Change |
|---|---|
| Earned income tax credit | Raised to a maximum of 3.6m won |
| Youth monthly-rent tax credit | 17% credit rate |
| Family business succession deduction cap | 60bn → 100bn won |
| Succession management-tenure requirement | 10 → 30 years |
| Income tax | Estimated 557.9bn won reduction over five years |
The succession provision moves in two directions at once. The cap rises substantially while the required tenure of the deceased owner-manager triples. The door widens and the eligibility narrows — concentrating relief on genuine long-tenure founders and largely excluding businesses acquired midway.
The government states four objectives: supporting a rebound in potential growth beyond the semiconductor upturn; supporting ordinary households, young people and regional economies; tax reform for fairness; and rationalization and administrative convenience.
4. Common questions
Where do I find the assessed value? Korea's official property price disclosure service publishes it by address. That figure, not market price, drives the calculation.
What about joint ownership? The holding tax is assessed per person, on each owner's share. How the residency condition applies to jointly held single homes will depend on the enforcement decree.
How is "actual residence" proved? The announcement did not specify. Registration, duration of stay, and exceptions for work or illness are enforcement-decree matters. This is the least settled part of the reform.
Should I buy or sell now? This publication does not give investment advice. The dates are worth noting: holding-tax changes proposed for 2027, capital-gains changes for 2028, with legislative review in between.
5. What remains unverified
The most important gap first. Some outlets reported the single-home threshold rising from 1.2bn to 1.4bn won regardless of occupancy, while most described the 1.4bn/900m split used here. The enacted text should be checked. The fair-market-value ratio increase and detailed rate brackets are reported inconsistently and need comparison against the government's detailed edition.
And the standing caveat: this is a government proposal. Korean tax law is settled by the National Assembly, and announced bills change.
