Tax Obligations You Must Handle Before Leaving Japan

Leaving Japan is an exciting milestone—whether you're heading home, moving to a new country, or starting the next chapter of your life. But before you pack your bags and head to the airport, there are some critical tax and financial obligations you need to take care of. Failing to handle these properly can result in unexpected bills chasing you overseas, loss of pension refunds, or complications if you ever return to Japan.

This guide covers everything foreigners need to know about tax obligations when leaving Japan, from filing your final tax return to claiming your pension refund and understanding Japan's exit tax rules.

1. File Your Departure Tax Return (確定申告)

If you earn income in Japan, you must file a tax return for the portion of the year you were a resident—even if you're leaving before the standard tax filing season (February 16 to March 15).

Two scenarios depending on your situation:

• Without a tax representative: You must file your final tax return by the day of your departure. Visit your local tax office (税務署, zeimusho) to do this in person.
• With an appointed tax representative: You can file by March 15 of the year following your departure, just like a regular resident.

Appointing a tax representative (zeimu dairi-nin, 税務代理人) is strongly recommended if you have any outstanding tax obligations. This person—usually a family member, friend, or professional tax accountant (zeirishi)—will handle your tax matters in Japan after you leave.

2. Understand Your Resident Tax Liability (住民税)

Resident tax (jūminzei, 住民税) is one of the most commonly misunderstood obligations when leaving Japan. Here's the key rule:

If you were living in Japan on January 1 of a given year, you owe resident tax for the entire previous fiscal year.

For example, if you leave Japan in February 2026, you will still receive resident tax bills in June 2026 for your 2025 income. The rate is approximately 10% of your previous year's income (4% prefectural + 6% municipal).

Your options:

• Pay the full outstanding amount before you leave
• Appoint a tax representative to handle future bills on your behalf
• Contact your municipal office to arrange a payment plan

If you don't designate a representative and leave without paying, your municipality may pursue you for unpaid taxes—which can cause complications if you return to Japan in the future.

3. Claim Your Pension Lump-Sum Withdrawal (脱退一時金)

If you've been contributing to Japan's public pension system (nenkin, 年金), you may be eligible for a lump-sum withdrawal payment after leaving the country.

Eligibility requirements:

• You are not a Japanese national
• You contributed to the Japanese pension system for at least 6 months
• You apply within 2 years of leaving Japan
• You no longer have an address in Japan

The withdrawal amount is based on how long you contributed, up to a maximum of 60 months (5 years). Note that contributions beyond 60 months are not refunded through this system—they only count if you have a social security agreement between Japan and your home country.

Tax on the withdrawal: A 20.42% withholding tax (including the Special Income Tax for Reconstruction) is automatically deducted from your lump-sum payment. However, you can apply for a partial refund of this withheld tax through a tax representative within 5 years of receiving the payment.

How to apply:

1. Leave Japan and deregister your address
2. Wait for your pension contributions to be processed
3. Submit a claim form to the Japan Pension Service (Nihon Nenkin Kikō)
4. Receive payment to your overseas bank account (processing takes 3–6 months)

4. Japan's Exit Tax: Are You Affected? (国外転出時課税)

Japan's exit tax (kokugai tenshutsu ji kazei) was introduced in 2015 and applies to certain high-net-worth individuals leaving the country. Understanding whether it applies to you is essential.

Who is subject to Japan's exit tax?

You are subject to the exit tax if you meet both of the following conditions:

1. You held financial assets worth JPY 100 million or more (~$700,000 USD) at the time of departure
2. You maintained a principal residence (jusho) or temporary abode (kyosho) in Japan on a Table 2 visa (permanent resident, spouse of Japanese national, long-term resident, etc.) for 5 or more years in the 10 years immediately before departure

Important: Time spent in Japan on a Table 1 visa (work visas such as engineer/specialist, skilled labor, professor, etc., or student visas) is not counted toward the 5-year threshold. Most working foreigners on standard work visas are therefore not subject to the exit tax, regardless of how much they hold in financial assets.

What assets are taxed?

The exit tax rate is 15.315% on the deemed capital gains from your financial assets, calculated as if you sold everything on the day of your departure.

Payment options:

• Pay immediately before leaving
• Defer payment by providing security equal to the tax amount (interest may apply)

For comprehensive information about the exit tax, Japan Dev's Exit Tax Guide provides an excellent breakdown. The RSM Japan Shiodome guide also covers exit tax implications for foreign executives.

5. Administrative Steps: Deregister Your Residence

Beyond tax filings, there are important administrative steps tied to your tax obligations.

Submit your move-out certificate (転出届, tenshutsu-todoke)

You must submit a move-out notification at your local municipal office (ward office, city hall, or town hall) before leaving Japan. This officially ends your status as a resident and:

• Stops further residence tax assessments
• Makes you eligible for the pension lump-sum withdrawal
• Prevents ongoing national health insurance premium notices

Timing: You can submit this up to 14 days before your departure date or shortly after. Once submitted, you'll receive a move-out certificate that you'll need for pension withdrawal applications.

Close or manage your bank accounts

Decide whether to close your Japanese bank accounts or keep them open. If you're expecting a pension refund or tax refund through a representative, you may want to maintain an account temporarily. Note that some Japanese banks restrict non-resident account management, so check your bank's policy before leaving.

6. Working with a Tax Representative and Professional Help

Given the complexity of Japanese tax procedures, many foreigners choose to work with a professional tax accountant (zeirishi) when leaving Japan.

A tax representative can:

• File your departure tax return on your behalf
• Handle ongoing resident tax payments after you leave
• Apply for pension tax refunds on your behalf
• Manage your Japanese bank account for refund receipt
• Respond to any inquiries from Japanese tax authorities

Finding a zeirishi who handles international cases is important. Many are listed through the Japan Federation of Certified Public Tax Accountants' Associations.
