Leaving Japan: The Final-Year Juminzei Trap

Leaving Japan residence tax does not leave with you. The bill for last year's income arrives in May to June, months after many departures.12

Confirm current details with official sources

Procedures, fees, and requirements can change. Confirm current details at your municipal tax office and the Ministry of Internal Affairs and Communications residence-tax pages. This article is general information, not tax advice; for your specific case, consult a licensed tax accountant (zeirishi).

Overview​

The trap is retrospective billing under the individual residence-tax system.31 Residence tax is billed in year N+1 for year-N income, so leaving in March of year X still leaves the year X-1 bill payable from May to June of year X.12

Whether a further assessment for year X itself exists turns on residency on January 1 of year X.14 This article owns those mechanics; the site's departure-checklist articles own the logistics, and they are linked at the end.

The diagram shows the departure decision tree. Confirm which January 1 branch you sit on, then pick one of the three settlement paths.

Which bills survive your departure​

Two assessments can follow you out the door. Work out which ones apply before booking anything nonrefundable.

Leaving in March of year X: the year X-1 bill still comes​

The assessment on year X-1 income bills in May to June of year X regardless of a March departure.12 Airport goodbyes in March do not cancel a bill that the January 1 rule already fixed.

This is the bill most departures miss, because it arrives after the farewell party. Budget for it as part of exit costs from the day you set a leaving date.

The January 1 pivot for year X itself​

Resident on January 1 of year X, a year-X assessment exists and stays payable after departure.14 Not resident on that date, and no year-X assessment arises at all.1

Partial year-X earnings enter a later assessment only where January 1 residency attaches.1 Short final stints that start after January 1 therefore generate less trailing liability than full years do.

January 1 is the whole departure analysis

Everything turns on where you were registered on January 1 of the departure year. Confirm the registration date on your records before choosing between prepayment and a representative.

Settling before you fly​

Three paths settle the trailing bills. Pick one deliberately; drifting into none of them is how arrears happen.

Lump-sum prepayment at the counter​

Departing residents are guided to pay unpaid taxes in one lump sum before leaving.2 Visit the municipal tax counter with your leaving date and settle the estimate on the spot.

Departure-year national-tax filing follows its own final-return clock, so handle it alongside the residence-tax settlement.5 One counter visit can queue both.

Appointing a nozei kanrinin​

Alternatively, designate a 納税管理人 (nozei kanrinin, "tax representative"): a proxy who receives the bill and pays it on your behalf after you leave.2 Appoint the representative by filing at the municipal office before departure.2

Appointment forms and handling vary by municipality, so confirm the local procedure directly.2 Choose someone reliable, fund the expected amount, and confirm they know the June arrival window.

Paying the notice from abroad​

Some municipalities support direct international billing and payment of the notice (as of 2026-01; confirm current handling with your municipal tax office).2 Availability varies, so verify before relying on this path.

Strong recommendation: leave nothing to chance

Appoint a nozei kanrinin or lump-sum pay before departure, even when international payment looks available. Redundant settlement beats a surprise arrears record.

What unpaid juminzei costs after departure​

Unpaid balances can be collected from remaining Japanese assets, and treaty-based cross-border assistance on tax claims exists in limited cases.1 The exposure is narrow but real, and it grows no smaller with time.

Unpaid departure-year tax also becomes visible at any future visa or re-entry record check.6 A clean exit preserves every future option; a skipped bill mortgages them.

Residence tax arrears and visa renewal screening​

Returnees and future applicants face the same screen as everyone else. Permanent residence screening requires proper performance of public duties including tax payment, and even late-paid tax is evaluated negatively in principle (as of 2026-02).6

The Financial and Tax Criteria for Permanent Residency explains how examiners read that record. Departure-year arrears count exactly like any other year's.

Good to know​

File the move-out paper before the tax paper​

The move-out notification (転出届, tenshutsu todoke, "move-out notification") ends ward registration but does not settle or redirect the tax bill.2 The representative filing is a separate step at the tax counter.

Tell the representative where the June notice goes​

The bill arrives in May to June after departure, so the representative needs the delivery address and the funds arranged before you fly.12 A named proxy with no address on file helps no one.

Keep proof of every departure-year payment for any return​

Payment certificates document the settled record for future visa paperwork.26 Store them with your pension and withholding slips, not in a box you will never open.
