Before leaving Japan, check two separate amounts: resident tax still being collected for the current tax year, and any new assessment that may arrive after you leave. Paying everything shown on your latest payslip does not necessarily settle both. A conversation with payroll and your municipality can prevent a gap in your departure budget.
Sources checked September 13, 2026. This guide covers general preparation for individual resident tax; your municipality determines your assessment and payment arrangements.
Separate the income year from the collection year
Individual resident tax, or Juminzei, is generally assessed using the previous calendar year’s income. For salary withholding, collection normally runs from June through the following May. For example, the FY2026 assessment generally relates to 2025 income, with salary deductions from June 2026 to May 2027. See Yokohama’s explanation of individual resident tax.
Ask payroll to identify the assessment year on your current deductions. Do not multiply one monthly deduction by twelve and assume that result is next year’s tax: taxable income, deductions and other assessment conditions may differ.
January 1 matters, but a flight date is not enough
Resident-tax liability is assessed according to your circumstances on January 1. Leaving partway through a year does not cancel that year’s assessment or reduce it to the months you remained. Yokohama’s overseas-departure FAQ explains that the year’s tax remains payable.
For tax purposes, domicile is judged from the facts of your life, including work, family and living arrangements. A temporary trip abroad on January 1 does not necessarily change it. Filing a moving-out notification is not a universal guarantee of exemption. See the Tokyo 23 wards’ resident-tax guide, printed page 18.
If your move is close to New Year, ask your municipality how it will assess your actual circumstances. Do not book a December flight on the assumption that it automatically makes the next bill zero. Existing arrears remain a separate obligation, and retaining premises can raise additional local-tax questions.
What payroll needs to check when you resign
For salary earners currently paying by special collection, the resignation date and available final payments affect collection of the remaining balance:
- January 1–April 30: the remaining tax is generally collected together without a separate request when salary or retirement payments payable by May 31 exceed the outstanding amount. If they do not cover it, confirm another payment arrangement.
- June 1–December 31: the balance is generally switched to ordinary collection unless arrangements are made for a requested lump-sum deduction or continued special collection at another employer.
- May: check the final installment of the collection cycle with payroll. Do not assume it also pays the new assessment starting in June.
These points follow Kawasaki’s explanation of tax after retirement. Confirm the handling of your departure with your own municipality and employer, especially if there is little final pay or no continuing Japanese payroll.
For a simple budgeting example, suppose payroll confirms three remaining installments of ¥20,000 each. That is ¥60,000 still to arrange for the current assessment. This arithmetic example is not an estimate of your tax and does not include a later assessment.
Arrange for notices that arrive after departure
Someone leaving in February 2027 may need to settle the remaining FY2026 installments and also arrange payment of an FY2027 assessment based on 2026 income. Do not wait for a June notice to discover that nobody can receive it.
A municipal tax representative can receive notices and handle the required payment procedures. For example, Yokohama requires advance arrangements for a tax representative when notices cannot be sent after an overseas move. Check who can act, the required form, and whether your municipality offers an advance-payment arrangement. Shinjuku’s resident-tax guidance describes advance payment or appointing a representative before notices are issued.
Confirm municipal arrangements separately from any national income-tax filing. Do not assume that appointing someone for a pension-related income-tax refund automatically completes the local resident-tax procedure.
Your departure action list
- Ask payroll for the current assessment year, remaining balance and final deduction date.
- Ask the municipal tax office whether a further assessment will follow your departure.
- Confirm the representative or advance-payment procedure and each payment deadline.
- Agree how notices, payment confirmations and funds will be handled after you move.
- Check your bank’s nonresident-account rules before relying on an existing payment route.
Use our bank-account preparation guide and departure checklist to record the next steps. Keep your confirmed tax obligations in your moving budget; avoid relying on an unconfirmed pension payment or tax refund to meet a fixed deadline.
