💡 The official land price is the government-assessed baseline for your land — and checking it online takes under 5 minutes once you know which platform to use.
What the Official Land Price Actually Means
Here’s something most homeowners don’t realize until they’re staring at a tax notice: your property tax isn’t based on what you paid for your home, or what it would sell for today. It’s based on a completely separate number — the official land price (romanized from Korean: gongsi jiga).
The government sets this figure annually. It’s a standardized valuation, intentionally detached from market swings.
Honestly, the gap between official land price and actual market value can be enormous — sometimes the official figure sits at 50 to 70% of real market value, sometimes higher in dense metro areas. That’s by design. But it means that your tax bill is calculated off a number that may look nothing like your property’s actual worth.
💡 The official land price is set by the government each year — it’s the number that directly determines what you owe in property-related taxes, not your market value.
A homeowner I know — early 40s, had owned his apartment for six years — had never once looked up his official land price. Not until he tried to refinance and his lender asked for a tax assessment breakdown. He was genuinely shocked that his land value (as the government saw it) was so different from what his agent had quoted him on the open market.
That gap is normal. But knowing it matters — especially at tax filing time.
The Platforms Where You Can Check the Official Land Price
Here’s the thing: several government-affiliated platforms let you check your official land price for free. No login required on most of them. The problem isn’t access — it’s knowing which platform matches your property type.

My personal go-to is the Real Estate Public Price System. I tested it last spring when I was estimating a tax liability before a purchase decision — clean interface, fast address search, and the year-by-year price history is genuinely useful for spotting assessment trends.
Am I the only one who finds the Land Information System a bit clunky? It’s powerful for parcels and agricultural land, but the interface feels like it hasn’t been updated in a decade. Functional. Just not fun.
How to Read the Data Once You Pull It Up
Okay, you’ve found your property. Now what?
The key numbers to look for:
- Gongsi jiga (official land price per square meter) — the core figure for land-only valuations
- Gongsi gagyeok (public announced price) — used for apartments and buildings; covers land and structure together
- Year of assessment — always confirm you’re viewing the most recent year (typically announced in April)
- Parcel number or building code — double-check this matches your property’s legal description exactly
Plot twist: the number listed isn’t always the final figure used for taxation. Local governments apply a fairness ratio (gongjeong sijang gaesan-yul) that adjusts the base official price before rates kick in. The listed official price is the starting point, not the taxable amount.
One thing I initially got wrong: I was confusing the per-square-meter price with the total land value. If your parcel is 200 sqm and the official land price is 1,200,000 KRW per sqm, your total assessed land value is 240,000,000 KRW. Simple math — but easy to miss when you’re skimming a data table fast.
💡 The per-square-meter official land price is not the same as your total assessed land value — always multiply by your parcel’s actual area.
Before You Use This Data for Filing
A couple of sanity checks before you close the browser tab.
First: make sure the property type matches what you searched. A standalone house and an apartment unit use different valuation systems. If the platform lists your apartment as “land only,” something’s off — go back and re-search.
Second: verify the announcement year. Official land prices in Korea are typically announced in late January and apply from January 1 of that year. If you’re checking mid-year, the platform should reflect the current year’s values — but some older portals lag by a cycle.
Third: cross-reference two platforms if you’re using the number for anything official. Discrepancies are rare, but they happen — and you don’t want to discover one after you’ve already filed.
Fifteen minutes of verification now can save a painful correction letter from the tax authority later.
