Japan expat tax guide
Asia · how a foreigner who moves to Japan is taxed · 2026 · Mixed
If you move to Japan, you become a tax resident when domicile or 1+ year residence; non-Japanese with up to 5 of last 10 yrs = non-permanent resident. As a resident you are taxed on a mixed basis — Permanent residents are taxed on worldwide income, but a non-permanent resident (a non-Japanese national resident 5 years or less within the preceding 10) is taxed only on Japan-source income plus foreign income paid in or remitted to Japan — a remittance basis for roughly the first 5 years. The top personal income tax rate is 45%. A foreign pension is treated as: Permanent resident: foreign pension taxed as worldwide income; non-permanent resident: only if paid in/remitted to Japan. Japan also offers the Non-permanent resident remittance basis regime, which can sharply change this picture. It has a US tax treaty and has a US totalization agreement. Overall it reads as mixed for an inbound mover. General information, not tax advice — verify with Japan's tax authority.

What this means if you relocate to Japan
The first thing that matters is tax residency: domicile or 1+ year residence; non-Japanese with up to 5 of last 10 yrs = non-permanent resident. Because Japan has no simple day count, residency turns on where your real home and life are, which is harder to plan around than a day rule.
Once resident, Japan taxes your worldwide income, so income earned abroad is in scope unless a treaty or special regime says otherwise. The top 45% rate only bites at the highest income band — an average earner pays less.
Foreign pensions and investments
Foreign pension: Permanent resident: foreign pension taxed as worldwide income; non-permanent resident: only if paid in/remitted to Japan. Foreign capital gains and dividends: Permanent resident: foreign capital gains/dividends taxed worldwide; non-permanent resident: only if paid in/remitted to Japan. These outcomes can be overridden by a double-tax treaty, which decides whether the source country or Japan taxes each stream — a key reason retirees should map their specific income against the relevant treaty.
The Non-permanent resident remittance basis regime
A non-Japanese national resident for 5 years or less within the preceding 10 years is taxed on foreign-source income only to the extent paid in or remitted to Japan. No dedicated retiree regime.
Special regimes have eligibility tests, time limits and sunset dates that change frequently. Treat the summary above as a starting point and verify the current terms with Japan's tax authority before relying on it.
US citizens and social security in Japan
| Question | Japan |
|---|---|
| US income tax treaty? | Yes |
| US social-security totalization agreement? | Yes |
| Tax basis for residents | Mixed |
| Top personal income tax | 45% |
A US tax treaty with Japan helps reassign taxing rights and reduce withholding, and US citizens lean on the Foreign Earned Income Exclusion and Foreign Tax Credit to avoid double income tax. A totalization agreement means you generally pay social-security contributions to only one of the two countries. See our guides on FEIE vs the Foreign Tax Credit and totalization agreements.
