Leaving Japan and Your Taxes

Leaving Japan doesn't end your tax obligations

If you're moving away from Japan permanently or for an extended period, your tax filing responsibilities don't automatically disappear the day you board your flight. Depending on your income and situation, you generally have two ways to handle your final year of taxes here. This guide walks through both, plus a few related loose ends worth tying up before departure. It's general information based on National Tax Agency guidance, not personalized tax advice — for anything involving real money, a licensed tax accountant (税理士) is worth the consultation fee.

Your two main options

If you leave partway through the calendar year, the NTA gives you a choice between filing before you go or arranging for someone to file on your behalf after you're gone.

Option A: File a quasi-final return before you leave (準確定申告)

You can file a return covering your income from January 1 up to your departure date, and submit it before you leave the country. This is sometimes called a 準確定申告 (jun-kakutei shinkoku, "quasi-final return") because it's essentially a shortened version of the normal 確定申告 (kakutei shinkoku) process, closed out early to match your actual departure date rather than waiting for December 31. If you're already unsure whether you need to file at all, it's worth starting with our overview at do I need to file taxes in Japan before working through the mechanics here.

Option B: Appoint a 納税管理人 (tax administrator) and file later

Alternatively, you can appoint a 納税管理人 (nouzei kanrinin) — a tax administrator or representative — before you leave. This person or entity then files your return on your behalf during the normal filing window of the following year, February 16 through March 15, exactly as if you were still a resident. The return still covers your income from January 1 through your departure date; it's just filed on the standard schedule instead of rushed before you fly out.

A 納税管理人 can be an individual who lives in Japan or a Japanese corporation. There's no requirement that they be a family member — a trusted friend, colleague, or a professional (such as a tax accountant's office) can serve in this role. Their job is to file your return, receive any correspondence from the tax office on your behalf, pay any tax owed, and receive refunds if you're due one. You appoint them by filing a "所得税・消費税の納税管理人の選任届出書" (notification of appointment of a tax administrator for income tax and consumption tax) with your local tax office before you depart. Note that appointing someone doesn't shift the responsibility entirely — you remain the person ultimately liable for accuracy and payment; the administrator is acting on your behalf, not replacing your obligation.

A timing wrinkle: departing early in the year

If you're leaving between January 1 and March 15, there's an extra wrinkle to watch for: the prior year's return may also still need to be filed before you go, in addition to any current-year quasi-final return. This is easy to overlook if you're focused only on wrapping up the year you're currently in, so it's worth checking your filing status for the previous year as part of your departure checklist.

Residency status splits mid-year

A departure partway through the year can split your tax year into two distinct periods: a 居住者 (resident) period, during which worldwide income is generally taxable in Japan, and a 非居住者 (non-resident) period afterward, during which only Japan-source income is generally in scope. Figuring out exactly where that line falls, and how income should be allocated between the two periods, is genuinely complex and depends heavily on individual facts — this is a case where working with a professional is the sensible move rather than trying to sort it out alone.

Other loose ends before you go

A few related items tend to come up around departure time, even though they're technically separate from the income tax filing itself:

• 住民税 (resident tax): This local tax is billed based on the prior year's income, which means a bill can arrive after you've already left, covering income you earned while still in Japan. Depending on timing, you may owe a prorated amount or need to settle an outstanding balance. Having a 納税管理人 in place can make it much easier to receive and handle this bill instead of it becoming a notice that never reaches you.
• Pension lump-sum withdrawal (脱退一時金): If you paid into Japan's pension system, you may be able to claim a lump-sum refund after leaving. This is a separate process from income tax filing, with its own application and timeline, so don't conflate the two — it deserves its own research once your tax filing plan is settled.
• Selling your car: If you own a vehicle, it needs to be sold or formally deregistered before departure rather than left in someone else's hands informally — ownership, taxes, and paperwork can otherwise follow you. See selling your car before leaving Japan for the practical steps.

Departure filing has enough moving parts — quasi-final returns, administrator appointments, prior-year catch-up, residency splits — that it's easy to miss a step. If anything above sounds like it applies to you, start by confirming your basic filing obligation and go from there; our FAQ covers many of the smaller questions that come up along the way.
