Non-Permanent Resident Tax Rules in Japan: What Foreign Residents Should Know
【Koshida Accounting Firm Column Date:】
Hello, my name is Taisei Koshida, and I am a certified public accountant and tax accountant.
I aim to assist non-Japanese business owners who need help with reading or writing in Japanese. If you find the Japanese tax return system challenging, I can help you with your tax filings.
Many people moving to Japan assume that all of their worldwide income becomes taxable immediately after they become Japanese tax residents.
In reality, Japan has special tax rules for non-permanent residents, and understanding these rules before moving to Japan can significantly affect your tax liability.
Understanding your tax residency before moving to Japan can often save significant tax and administrative costs later.
1. What Is a Non-Permanent Resident?
Japanese tax law categorizes individuals as follows for individual income tax purposes:
(1) Resident:
An individual who has a domicile in Japan or has had continuous residence for more than a year.
① Non-permanent Resident:
Among residents, those who do not have Japanese nationality and whose period of having a domicile or residence in Japan totals less than five years over the past ten years.
② Permanent Resident:
Any individual who is not a non-permanent resident.
(2) Non-resident:
Any individual who is not a resident.
2. Taxable Income for Each Category
Permanent residents are generally taxed on their worldwide income.
Non-residents are generally taxed only on Japanese-source income.
Non-permanent residents are generally taxed on Japanese-source income and certain foreign-source income to the extent it is subject to Japan’s remittance-based taxation rules.
Many people mistakenly believe that becoming a Japanese tax resident immediately makes all overseas income taxable in Japan.
For non-permanent residents, however, foreign-source income is generally subject to Japan’s remittance-based taxation rules. Understanding this distinction is one of the most important aspects of Japanese tax planning for new residents.
3. Remittance-Based Taxation
When foreign nationals move to Japan to start a business or establish a company, they often change their tax status from non-resident to non-permanent resident.
At that point, remittance-based taxation becomes an important issue.
If foreign-source income is earned during the same calendar year in which funds are remitted to Japan, part of that income may become taxable in Japan.
Careful planning before moving to Japan can often reduce unnecessary tax exposure.
4. Practical Considerations Before Moving to Japan
In my experience, many foreign residents focus on visa status when moving to Japan but overlook the importance of tax residency status.
Understanding the non-permanent resident rules early can help avoid unexpected tax liabilities and allow for more effective financial planning.
