The Global Expat Hub
South KoreaThe guide's tax headline for South Korea is a 19% flat-tax option for foreign workers lasting 20 years, alongside property tax at 0.1–0.4% plus a Comprehensive Real Estate Tax on high values, and local income tax at 10% of national tax. It is deliberately advice-heavy and rate-light beyond those figures: it budgets for professional tax and estate advice at several points, and points readers to English translations of Korean statutes for the law itself.
The 19% flat-tax option: foreign workers, 20 years
The guide lists among its “schemes that attract expats”: “19% flat-tax option for foreign workers for 20 years.” The site data carries the identical line. Two things follow from the guide's own wording, and only those two are claimed here: the option is aimed at foreign workers, at a 19% flat rate for 20 years. The guide gives no eligibility list, no start-date or election rules, and no treatment for pension income under the option — so none is stated here.
Property and local taxes the guide does state
Property tax: 0.1–0.4% plus Comprehensive Real Estate Tax on high values — the guide's “Taxes (property)” line, matched exactly in the site data. The guide gives no threshold for what counts as a high value and no rate for the Comprehensive Real Estate Tax, so neither is stated here. The guide's numbers page adds a land note: rural land is $30,000+ per acre for farmland; foreigners can buy with approval.
Local income tax: 10% of national tax. The guide gives no national income-tax bands or rates, so this page publishes none.
At the guide's rate of $1 ≈ ₩1380, won-denominated values convert at roughly that rate for planning.
The other schemes the guide names
Alongside the flat-tax option, the guide's schemes list is short and specific: the Workation nomad visa, National Health Insurance after 6 months, and Jeju investor residence. University costs are also stated on the numbers and living pages: not free; national universities $4–6k/yr, private $8–12k/yr, many scholarships. The Jeju scheme is named without amounts, administering bodies or eligibility rules in either source, so it is flagged here as a lead to research — starting from the official legislation source below — rather than described in detail this page cannot source.
U.S. expats: the obligations the guide actually covers
Be clear about what this guide does not do: it contains no U.S. filing rules — no mention of U.S. returns, foreign-account reporting, exclusions or credits — and the site data adds none. What the guide does, consistently, is budget and prompt for advice at the points where U.S. obligations bite:
- Before you become resident — the Luxury timeline takes “tax structuring advice before you become resident,” and the Mid-range checklist includes “tax advice taken on residency timing.”
- For retirees — a $1,500 line for tax and estate advice covering double-taxation, pension treatment and wills, plus checklist advice on your tax residency date and the pension treaty.
- Official U.S. channel — the guide lists the U.S. Embassy in South Korea among its official sources, and the Retirement checklist includes registering with the embassy or consulate.
That is the sourced position: take advice before residency, especially on double-taxation and pension treatment. Anything more specific about U.S. obligations would be unsourced here.
Legal and residency basics, with the official sources
The guide's official-law entry point is the Korea Legislation Research Institute (English statutes), listed with its URL in the guide and the site data; the site data also links a Wikipedia law overview from the country page. Everyday legal basics the guide does state: South Korea drives on the right, and after a move the settle stage includes registering your address and opening a bank account. For retirees, the checklist adds preparing a local will and power of attorney. The guide's own closing disclaimer applies to this whole page: figures were current at publication in 2026, tax rules and visa schemes change, and the guide is not legal, immigration or financial advice — verify against the official sources before you rely on them.
