Leaving Japan: Complete Tax & Financial Checklist for Foreign Residents | TaxMatch Japan

Leaving Japan involves a surprisingly complex series of tax and financial obligations — many with strict deadlines and significant financial consequences if missed. This is the complete checklist every foreign resident needs before their departure date.

Most foreign residents assume leaving Japan is simply a matter of canceling their residence registration and booking a flight. In reality, your Japan tax obligations can extend years beyond your departure date — and failing to handle them correctly before you leave can result in penalties, withheld refunds, or even legal complications. This checklist covers everything from 6 months before departure through your final tax filing.

Leaving Japan? Here is your tax checklist

Step 1: Check Your Tax Status on Departure

Leaving Japan: Tax Timeline — What to do and when

Are You a Tax Resident Until You Leave?

Japan taxes individuals as residents if they have a 住所 (jūsho) — their permanent, primary place of living — in Japan. You are a Japan tax resident from the day you arrive until the day you formally depart. This means:

• All worldwide income earned up to your departure date must be declared in Japan
• Income earned after your departure date (if you are no longer a Japan resident) is generally not subject to Japan income tax
• Japan-source income earned after departure (e.g., rental from Japan property, Japan company dividends) remains subject to Japan withholding tax

Non-Permanent Resident vs. Permanent Resident Status

If you have lived in Japan for 5 years or fewer out of the past 10 years, you are a Non-Permanent Resident (NPR). Under NPR status, only Japan-source income and foreign income remitted to Japan is taxed. This distinction matters for your final year tax return — ensure you understand which income you need to declare.

Step 2: The January 1 Rule — Timing Your Departure

The January 1st Rule: How 6 days can save you ~¥1,000,000

Example: The Cost of a January vs. December Departure

Step 3: Exit Tax — Do You Qualify?

Japan’s exit tax (国外転出時課税) applies if you meet both conditions:

• Asset threshold: You hold ¥100 million or more in specified financial assets (stocks, mutual funds, bonds — NOT real estate or cash)
• Residency duration: You have held a Table 2 visa (Permanent Resident, Spouse of Japanese National, Long-Term Resident) for a cumulative total of 5+ years out of the past 10 years

If you meet both conditions, see our dedicated Exit Tax guide for full details on calculation, deferral options, and planning strategies. Key point: appoint a tax representative (納税管理人) before leaving Japan to preserve your deferral options.

Step 4: Final Japan Tax Return (準確定申告 or 確定申告)

Who Must File a Final Return?

You must file a Japan income tax return for your final year of residence if:

• You had income beyond employment income subject to year-end adjustment (年末調整)
• You had freelance, investment, or rental income
• You are claiming the exit tax deduction or any special deductions
• You overpaid taxes and want a refund (highly recommended — most departing employees are due refunds)

Filing Deadline for Departing Residents

Step 5: Pension Lump-Sum Withdrawal (脱退一時金)

If you contributed to Japan’s national pension (国民年金) or employee’s pension (厚生年金) as a foreign resident, you are entitled to a lump-sum withdrawal (脱退一時金) after leaving Japan — provided you do not have Japanese nationality and have not met the full pension eligibility requirements.

Eligibility and Amount

Countries with Social Security Totalization Agreements

If your country has a totalization agreement with Japan (including the US, UK, Germany, Australia, Canada, South Korea, China, and others), pension periods in Japan may be combined with your home country for eligibility purposes. In some cases, claiming the lump-sum withdrawal forfeits your ability to use Japan pension years in home-country totalization. Seek advice before applying.

Step 6: National Health Insurance (NHI) and Employee Health Insurance

Canceling NHI (国民健康保険)

If you are on NHI (self-employed or not covered by employer), cancel your NHI enrollment at your local municipal office (市区町村) on or around your departure date. Bring your NHI card. You will receive a statement of cancellation which may be needed for your tax return.

Employee Health Insurance (健康保険)

If you are employed, your employer handles health insurance termination when your employment ends. However, if your employment ends before your departure, you may choose to continue enrollment (任意継続) for up to 2 years. The premium is the full amount (approximately double what you paid as an employee) — this is rarely worthwhile for departing residents.

Outstanding NHI Premiums

Any unpaid NHI premiums remain legally owed after departure. Unpaid amounts can be collected from your tax refunds and may affect visa applications for future Japan re-entry.

Step 7: Banking and Investment Accounts

Japanese Bank Accounts

You are technically not allowed to maintain Japan bank accounts as a non-resident (though in practice, accounts are often maintained for months or years). Options:

• Close the account before departure: Simplest option; transfer funds overseas and close
• Maintain the account: Inform your bank of your change to non-resident status; they will convert it to a non-resident account. Allowed under most banks’ policies. Required for pension lump-sum refund deposits and tax refunds.
• Do NOT simply leave without notifying the bank: Interest accruals and eventual dormancy fees create complications

NISA Accounts

iDeCo (Individual Defined Contribution Pension)

iDeCo contributions must stop when you lose Japan resident status. Your accumulated iDeCo balance remains invested until you reach the eligible withdrawal age (currently 60-75, depending on enrollment duration). You cannot make withdrawals as a non-resident in most circumstances. Consult your iDeCo provider for your options.

Japanese Brokerage Accounts

Most Japanese securities companies will close brokerage accounts for non-residents. You must sell or transfer your holdings before departure, or arrange a transfer to a foreign brokerage. Note: selling Japanese securities before departure triggers Japan capital gains tax in the usual way (20.315%).

Step 8: Residence Deregistration (転出届)

File a 転出届 (tenshutsu todoke) — moving-out notification — at your local municipal office. This:

• Cancels your residence registration (住民票)
• Returns your Residence Card (在留カード) — it is cut or cancelled at the airport upon departure
• Triggers the start of your non-resident status for municipal tax purposes
• Can be done up to 2 weeks before your departure date, or on the day you leave

4 Common Mistakes When Leaving Japan

1. Leaving without appointing a tax representative — Forces you to file and pay all taxes before boarding, often at unfavorable valuations. And you lose deferral rights for exit tax.
2. Forgetting the 2-year pension lump-sum window — Many expats leave, forget about it, and miss the 2-year deadline. At 5 years of contributions, this can be ¥500,000–¥2,000,000+ depending on your contribution history.
3. Not closing or converting NISA within 3 months — The automatic conversion to a taxable account creates complex tax complications and costs future gains their tax-free status permanently.
4. Ignoring the January 1 rule — Departing in early January instead of late December costs a full year of local inhabitant tax (10% of prior year income). For high earners, this mistake costs millions of yen for a few days of difference.
