Resident Tax in Korea: The Small Bill Every Registered Foreigner Gets Each August

Every August, a small envelope or a Kakao alert from your district office lands on a lot of foreign residents in Korea for the first time, for an amount that looks suspiciously specific — ten-thousand-some won, no English anywhere on it, sent by an office you've never heard from before. It isn't a scam, a parking fine, or a bill collector. It's 주민세 개인분, the per-capita resident tax, and if you've been registered in Korea for a year or more, you very likely owe it.

A government bill, not a phishing attempt

Resident tax (주민세) is a flat, small local tax that funds the basics a city runs day to day — not income-based, not tied to how much you earn, and not the same thing as the tax withheld from a paycheck. The two get confused constantly, including by people who've lived in Korea for years, because the names sound alike:

Who actually owes it

Under the Local Tax Act (지방세법), the taxpayer is whoever has an address — for a foreigner, a registered place of stay under the Immigration Act — in the municipality on the tax base date: July 1 every year. Two carve-outs matter for foreign residents specifically:

• July 1Tax base date — your registered address that day decides which city bills you
• 1 yearHow long you must have held foreign registration before a city can tax you (Art. 75)
• Aug 16–31The payment window every year (Art. 79)
• ₩10,000Statutory cap on the base rate, before each city's local education tax add-on (Art. 78)

If less than a year has passed since your foreign registration date as of July 1, you're excluded outright — a first-year student or new hire typically owes nothing the first summer. Basic livelihood recipients and most minors are excluded too, and some cities reduce the bill further for residents 80 and older, by local ordinance rather than national law.

How much, and why no one figure is right

The law caps the base rate at ₩10,000 per person — or up to ₩15,000 if residents petition their city for a higher rate, which can then vary by neighborhood. On top of that, every city adds a local education tax equal to 25% of the base amount, which is why a real bill almost never lands on a round number. In August 2026, Pohang's Buk-gu district billed 108,457 individual notices totaling about ₩1.18 billion — averaging roughly ₩10,900 each — to household heads and foreign residents who'd held registration there for a year or more, exempting basic livelihood recipients and unmarried household heads under 30.

That's one city, one year. Yours will differ. Rather than guess at a number, check the amount on your own notice, or look it up through Wetax (위택스), the nationwide portal for local taxes, before assuming any figure you've read online — this one included — matches what you actually owe.

What Soo House sees every August

Soo House connects expats and foreign residents across Korea with paid brand campaigns, creator classes and community meetups, and our own app ships with an Address Management screen members use to keep a current shipping address on file for the products those campaigns send out. Every August, the same question shows up in our community chat without fail: a photo of a small government notice, usually assumed to be a scam, because nothing about it looks like anything a newcomer to Korea has seen before. It's juminse — and the pattern we keep running into isn't confusion about the tax itself once someone explains it, it's that the notice goes to whatever address a resident had on file with the city on July 1. Members who move often between officetels and share houses between campaigns, and who keep their Soo House shipping address current but forget the separate government move-in report, can end up with a notice chasing them to a city they've already left.

What happens if you miss the window

Miss the August 16–31 deadline and a penalty — governed by the Framework Act on Local Taxes (지방세기본법) rather than the resident tax law itself — kicks in automatically, starting the day after the deadline and growing the longer it sits unpaid. The exact rate and how it's calculated have been subject to recent changes, so don't estimate it yourself: your city's follow-up notice, or Wetax directly, will show the current penalty on what you owe. Left unpaid long enough, it escalates to a formal collection notice, and eventually to the kind of account or asset action local tax offices are legally allowed to take on any unpaid local tax, foreign resident or not.

Your next hop: if you've held foreign registration in Korea for a year or more, check your mailbox and your district office's Kakao channel in mid-August — and if a small, unfamiliar notice turns up, confirm it on Wetax or by calling 120 (Dasan Call Center, multilingual) before deciding it's either spam or safe to ignore.

Checked in October 2026. The per-capita resident tax's July 1 tax base date, the August 16–31 payment window, the ₩10,000 statutory cap (up to ₩15,000 by resident petition), and the one-year-since-foreign-registration threshold for foreign taxpayers are drawn from Articles 75, 78 and 79 of the Local Tax Act (지방세법), as published on the National Law Information Center. The 2026 Pohang Buk-gu example — 108,457 individual bills totaling roughly ₩1.18 billion, with basic-livelihood recipients, unmarried household heads under 30 and an 80-and-older reduction carved out by local ordinance — is from a Gyeongbuk Maeil report dated August 6, 2026. The 25% local-education-tax add-on on top of the base rate is explained on Seoul city's own resident-tax notice page; the specific amount shown there dates to 2021, so confirm this year's figure for your own city through Wetax or your notice rather than relying on any amount quoted here. The late-payment penalty mechanism is governed by the Framework Act on Local Taxes (지방세기본법); its exact current rate has changed recently enough that we're not quoting a number — check Wetax or your follow-up notice for what applies now.
