The same officetel — a Korean studio-style unit legally classified as an office but often lived in — counts as a home for acquisition tax and does not count for housing subscription. Each rule has its own test. Acquisition tax turns on the purchase date of 12 August 2020 and on how property tax is assessed; capital gains tax looks only at actual use. For cheongyak (the housing subscription lottery), owning one still leaves you classified as a non-homeowner if it is small and cheap enough.
One principle runs through all of it. The Seoul city media hub states that a building is judged a home when it is "in fact used for residential purposes, regardless of permits or the registered use on official records." Its legal classification as a business facility is only the starting point; how it is actually used overrides it.
Buying one costs 4.6%, and only 4.6%
According to the Korea Economic Daily, acquiring an officetel carries a 4.6% rate: 4% base acquisition tax plus 0.4% local education tax and 0.2% special rural development tax. Owning several apartments does not change that figure, because the multi-home surcharge does not apply here.
The confusion starts one step later. The officetel's own acquisition tax is never surcharged, but it adds to your home count when you buy something else. The same article notes that someone holding three officetels who then buys an apartment can face a 12% surcharged rate on that new apartment.
Four ways an officetel drops out of the count
Not every unit is counted. Drawing on the Seoul city material, there are four situations:
- Acquired on or before 11 August 2020 — the amended local tax law is not applied retroactively.
- Assessed for property tax as a business facility — if it is not subject to residential property tax, it does not enter the count.
- Assessed value of 100 million won or less — excluded even where residential property tax applies.
- Conversely, a unit acquired on or after 12 August 2020 and taxed as residential is counted as a rule.
What one extra unit does to the bill
Assume someone who already owns one apartment buys another in a regulated zone for 800 million won. The table calculates the base acquisition tax for each possible status of an officetel they hold. Base tax only; local education and rural development taxes are excluded.
| Holdings | Homes counted | Base rate (%) | Base acquisition tax (10k won) |
|---|---|---|---|
| One apartment only | 2 | 8 | 6,400 |
| Apartment + officetel acquired before 12 Aug 2020 | 2 | 8 | 6,400 |
| Apartment + officetel taxed as business use | 2 | 8 | 6,400 |
| Apartment + residential officetel assessed at 100m won or less | 2 | 8 | 6,400 |
| Apartment + residential officetel bought after 12 Aug 2020, above 100m won | 3 | 12 | 9,600 |
The gap between the bottom row and the rest is 32 million won. A single paperwork distinction — whether the assessed value clears 100 million won, whether property tax is billed as residential — moves that much. Where the purchase date falls near August 2020, the registered acquisition date on the property register is the first thing to check.
An officetel does not change the tax on the unit you are buying. It changes the tax on the home you buy next.
Capital gains tax ignores dates and values, and looks only at use
For capital gains tax the test gets simpler and the exits narrower. Neither the acquisition-date grandfathering nor the 100 million won threshold applies. If the unit is let residentially and the tenant lives in it, it counts. The Seoul material likewise states that a unit actually used residentially is treated the same as any other home.
The consequence is loss of the one-home-per-household exemption. Someone holding an apartment and a residential officetel who sells the apartment is taxed as a two-home seller. The test applies at household level, so a unit registered to a spouse or another household member is caught as well.
Why housing subscription treats it as nothing
Subscription rules run differently. Newsis reported that owning a non-apartment dwelling, officetels included, still leaves an applicant classified as a non-homeowner if it meets the small-and-low-value test. That test was then set at 60㎡ or less of exclusive floor area with a published price of 160 million won or less in the capital region and 100 million won elsewhere — and its scope widened from private general supply to first-time special supply and public housing.
The bar then moved again. According to Bizwatch, the non-homeowner threshold was raised to 85㎡ or less with a published price of 500 million won or less in the capital region and 300 million won elsewhere — more than a threefold increase in the capital-region price ceiling.
| Tax or rule | What determines the count | Exclusion or relief |
|---|---|---|
| Acquisition tax | Purchase date + property tax classification | Bought before 12 Aug 2020 / business-use property tax / assessed value 100m won or less |
| Capital gains tax | Actual use | Genuinely used and let as business premises |
| Housing subscription | Floor area + published price | 85㎡ or less, 500m won capital region / 300m won elsewhere |
The small new-build relief running to 2027
The package Bizwatch described also carries a temporary relief: buy a non-apartment dwelling of 60㎡ or less and, through 2027, it is excluded from the home count and from surcharges on acquisition tax, comprehensive real estate tax and capital gains tax. The purchase price ceiling is 600 million won in the capital region and 300 million won elsewhere, and rental registration is required.
All three conditions bind at once. Exceed 60㎡, exceed the price ceiling, or skip rental registration, and the relief lapses and the general rules above return. The window is also time-limited, so a purchase completed after it closes falls outside regardless of the other conditions.
What to check
- The acquisition date on the property register — before or after 11 August 2020 is the first fork for acquisition tax.
- The classification on the property tax notice — residential or building (business use). The acquisition tax test follows this.
- The 100 million won assessed-value line — this is the officially published assessed value, not the market transaction price.
- Floor area and published price — for non-homeowner status in subscription, check against 85㎡ and 500m/300m won.
- Names within the household — capital gains tax is assessed per household, so a spouse's residential officetel counts too.
- The three relief conditions — 60㎡, the price ceiling, and rental registration. Miss any one and the general rules apply.
