Taxes in Japan for foreign residents
Tax residency, worldwide vs Japan-source income, remittances, foreign-tax credits, and moving or leaving Japan.
Your tax residency category (not your visa) decides what Japan can tax: non-residents on Japan-source income, non-permanent residents also on foreign income paid in or remitted to Japan, and permanent residents on worldwide income — with treaties and the foreign-tax credit reducing double taxation.

Key points
- Tax residency ≠ immigration status; you can be a tax resident from day one if facts establish a domicile.
- “183 days” is not Japan’s universal residence test — domicile and one-year residence are the domestic tests.
- Non-permanent residents (≤5 of last 10 years) are taxed on remitted foreign income, not just Japan-source.
- Work performed in Japan is Japan-source even when paid into a foreign account by a foreign employer.
Residency and what Japan taxes
For income tax, you are a non-resident, non-permanent resident, or permanent resident — a tax concept separate from the immigration “permanent resident.” Non-residents are taxed only on Japan-source income; non-permanent residents (non-Japanese who have had a domicile or residence in Japan for no more than five of the last ten years) are also taxed on foreign-source income paid in or remitted to Japan; other residents are taxed on worldwide income. Domicile is your settled center of life — occupation, family, housing, and assets — not a day count, so do not treat “183 days” as the test.
Remittances, credits, and moving
Remitting overseas income to a Japanese account can create tax for a non-permanent resident under source and ordering rules — do not assume only money kept abroad is safe. A Japanese resident can claim a foreign-tax credit for qualifying foreign income taxes, limited by Japanese ceilings and requiring country, income-category, and payment documentation. When moving in, preserve arrival dates, asset cost basis, equity-compensation records, and remittance records; when leaving, settle the departure-year return and resident tax and appoint a tax agent (納税管理人) if filings, refunds, or notices will arise after you go.
Who this is for
- Newcomers and long-term foreign residents
- People with foreign income, assets, or employers
What this is not
- Treaty- or country-specific advice
- US citizenship-based filing (see a US specialist)

Frequently asked questions
How does tax residency work in Japan?
For tax, Japan classifies you as non-resident, non-permanent resident, or permanent resident — separate from your immigration status. Broadly: non-residents are taxed only on Japan-source income; non-permanent residents (in Japan under 5 of the last 10 years, without permanent intent) are taxed on Japan-source income plus foreign income paid in or remitted to Japan; permanent residents (for tax) are taxed on worldwide income. This affects foreign income and investments, so confirm your category with the NTA or a tax accountant.
Do I need to file a tax return in Japan?
Many employees do not, because tax is settled by year-end adjustment (年末調整). You generally must file (確定申告) if you have side income over ¥200,000, two or more employers, self-employment income, sizeable investment or crypto gains, or you want to claim deductions like large medical costs or a first-year mortgage credit. Filing season is Feb 16 – Mar 15 via e-Tax. When unsure, check the NTA guidance or ask a 税理士.
