Foreign Resident /
Non-resident Self-Check

Enter your days in Korea, occupation, and family situation, and we'll self-check for free whether you're a Korean tax resident or non-resident.

한국어 · 日本語 · 中文
Why residency status matters — Residents are taxed on worldwide income through comprehensive taxation, while non-residents are taxed only on Korean-source income. The deductions, rates, and filing method that apply to you depend entirely on this determination, so it's the first thing to check.
days

From 2026, the 183-day count is no longer limited to a single tax year — a continuous stay spanning two tax years is combined. If you entered in the second half of last year and are still here, enter the combined total.

If you're also a resident of your home country, the tax treaty's dual-resident tie-breaker rules may additionally apply.

Self-Check Result

Holding permanent residency has no bearing on your tax residency status. The determination is based solely on objective facts about your time in Korea and living arrangements — family, assets, occupation.

This result is a reference self-check based on what you entered, not a formal determination under tax law. The actual determination can vary based on individual facts, so please confirm the exact answer through a consultation.
