Introduction: The Overlooked Issue of “Post-Departure Resident Tax”
In August 2026, a survey conducted by the Ministry of Internal Affairs and Communications revealed that the resident tax delinquency rate among foreign workers who left Japan after working here reached 18.6%. This figure significantly exceeds the overall delinquency rate of 4.6% for all departing residents, including Japanese nationals, highlighting a challenge unique to foreign workers.
As Japan continues to globalize, the acceptance of foreign workers has been steadily increasing. However, this survey has brought to light a troubling reality: many foreign workers are inadvertently failing to fulfill their tax obligations before returning to their home countries, due to insufficient understanding of the tax system and gaps in the institutional framework.
This article is intended for foreign residents and their families living in Japan, as well as business owners and HR managers who employ foreign workers. We will provide a detailed explanation of how the resident tax system works, the causes of unpaid taxes, and specific measures to prevent this issue.
What is Resident Tax? Understanding the Basic System
Basic Structure of Resident Tax
Resident tax is a local tax levied by prefectures and municipalities on residents. It is based on income earned from January 1 to December 31 of the previous year, and is typically paid in installments from June of the following year through May of the year after that.
This “pay-later” system—where tax is assessed on the previous year’s income and paid the following year—is a major factor contributing to the unpaid tax problem among foreign workers.
How Resident Tax is Collected for Salaried Workers
For company employees, resident tax is usually withheld from monthly salaries (special collection). However, depending on the timing of resignation or departure from Japan, employees may need to pay the remaining resident tax in a lump sum.
Why is the Delinquency Rate Higher Among Foreign Workers?
1. Insufficient Awareness of the System
Many foreign workers do not fully understand that resident tax operates on a pay-later basis. In particular, the possibility that tax obligations may arise after returning to their home country is often not adequately explained at the time of entry or employment.
2. Language Barriers
Tax notices and explanatory documents are almost always written in Japanese. For foreign workers who do not have sufficient Japanese language skills, understanding the complex tax system is extremely difficult.
3. Absence of Post-Departure Enforcement Systems
There is no established mechanism to enforce the collection of resident tax from individuals who have left Japan and are residing overseas. As a result, once someone returns home without paying, collection becomes virtually impossible.
4. Inadequate Procedures at the Time of Resignation or Departure
In some cases, employers fail to properly inform foreign employees about how to pay resident tax when they resign or leave Japan. Employees may depart without the necessary procedures being taken to withhold the lump sum from their final salary.
Details of the Ministry Survey: What the Numbers Reveal
Key Findings
According to the survey, which received responses from approximately 1,100 municipalities nationwide, the situation for fiscal year 2024 is as follows:
- Total resident tax due: approximately ¥5.8196 trillion
- Total delinquent amount: approximately ¥44.2 billion
- Tax due from all departing residents: approximately ¥23.4 billion; delinquent amount: approximately ¥1.1 billion (delinquency rate: 4.6%)
- Tax due from foreign departing residents: approximately ¥5.2 billion; delinquent amount: approximately ¥1.0 billion (delinquency rate: 18.6%)
The delinquent amount from foreign departing residents accounts for nearly the majority of the total delinquent amount from all departing residents, illustrating the severity of the problem.
Limitations of the Survey and Future Challenges
Many municipalities did not respond to the survey, suggesting that the actual delinquent amount may be even larger. Additionally, the number of delinquent individuals remains unknown, indicating a need for more detailed investigation.
Specific Measures Foreign Workers Should Take
1. Verify Resident Tax Before Departure
Once you decide to return to your home country, contact the tax office of the municipality where you currently reside to confirm whether you have any unpaid resident tax. Since tax on the previous year’s income is assessed the following year, you may have a tax obligation that arises after your departure.
2. Consider Lump-Sum Payment
You can pay the remaining resident tax in a lump sum when you resign or leave Japan. If you request it, your employer can withhold the lump sum from your final salary or severance pay.
3. Appoint a Tax Agent
If you still have a resident tax obligation after returning home, you can appoint a relative, friend, or professional residing in Japan as your “tax agent” (nozei kanrinin). The tax agent will receive tax notices and handle payment procedures on your behalf.
4. Consult a Specialist
By consulting with specialists such as administrative scriveners or tax accountants who are knowledgeable about visas and taxes, you can receive appropriate advice tailored to your situation.
Measures Employers Should Implement
1. Orientation at the Time of Hiring
When hiring foreign employees, it is important to explain the resident tax system in their native language or a language they understand. Clearly communicate that it is a pay-later system.
2. Support System for Resignation and Departure
When a foreign employee resigns or leaves Japan, provide the following support:
- Assistance in verifying resident tax payment status
- Information on lump-sum payment procedures
- Explanation of the tax agent system
- Withholding the lump sum from the final salary if necessary
3. Provide Information in Multiple Languages
Prepare materials about resident tax in multiple languages to create an environment where foreign employees can easily understand.
4. Collaborate with Specialists
If it is difficult to handle everything internally, collaborate with visa and tax specialists to establish an appropriate support system.
What Happens If You Leave Without Paying?
Impact on Visa Applications
If you apply for re-entry to Japan or a visa in the future, a history of unpaid taxes may affect the screening process. Particularly for work visa or permanent residency applications, fulfillment of tax obligations is an important consideration.
Impact on Credit Information
Tax delinquency can affect your credit information and may result in disadvantages if you consider resuming life in Japan in the future.
Legal Issues
Failure to pay resident tax is a breach of legal obligation, and late payment fees will accrue. If left unaddressed for a long period, enforcement procedures such as asset seizure may be initiated (though the practical effectiveness of such measures after departure is limited).
Measures Required of Government and Local Authorities
Multilingual System and Thorough Awareness
It is essential to provide tax-related notices and explanatory materials in multiple languages, making information accessible to foreign workers.
Pre-Departure Tax Verification System
A system should be established at airports or immigration offices to verify resident tax payment status before departure.
International Collection Cooperation Framework
Through bilateral agreements and other means, mechanisms should be developed to appropriately collect resident tax from foreign nationals even after they have returned home.
Strengthened Guidance for Employers
It may be advisable to mandate that companies employing foreign workers provide appropriate information and support regarding resident tax.
Conclusion: Prevent Problems with Correct Knowledge and Appropriate Action
The issue of unpaid resident tax among foreign workers is not primarily due to intentional non-payment by individuals, but rather insufficient awareness of the system and structural challenges.
For Foreign Workers
Be sure to verify your resident tax payment status before returning home, and take appropriate measures such as lump-sum payment or appointing a tax agent. It is important to take action now to avoid any negative impact on your future life in Japan or visa applications.
For Business Owners and HR Managers
When employing foreign workers, comprehensive support that includes tax matters—not just compensation and working conditions—is essential. At the time of resignation or departure, provide appropriate information and procedural support regarding resident tax to prevent disadvantages for your employees.
By having the correct knowledge and taking appropriate action, both foreign workers and employers can prevent unnecessary troubles.
If you have concerns about visa applications, residence status, or tax procedures including resident tax, we recommend consulting with a specialist.
