Can foreigners use Furusato Nozei?
The system is a deduction and credit against Japanese taxes; it is not a citizenship benefit. In ordinary cases, a foreign resident paying Japanese income tax and individual resident tax can make eligible donations and claim the associated relief within their personal limits.
The National Tax Agency describes the Furusato deduction for a person who donates to a local government and separately states that donation deductions apply to the taxpayer who personally pays the donation. Use your own name, address and payment method consistently.

Start with the taxes you actually expect
A Japanese salary is not by itself the limit. The calculation uses taxable income, resident-tax amounts, deductions and the applicable income-tax rate. Overseas income may also affect the result depending on residence classification and remittance rules. A generic salary table cannot resolve those questions.
If you arrived in Japan during 2026, remember that individual resident tax is generally linked to your status and address on January 1 and to prior-year income. A new arrival may not yet have the resident-tax base that a standard calculator assumes. Ask your municipality or adviser before making a large donation.
Choose the filing route carefully
One-Stop can be convenient for an employee who does not otherwise file a final return and donates to five or fewer municipalities. If you file because of overseas income, side income, medical expenses or any other reason, the final return must include all Furusato donations and any One-Stop applications become invalid.
Paper One-Stop applications normally require My Number and identity verification. Some municipalities support online applications, but the supported system varies. See the complete One-Stop guidebefore relying on it.
Cases that need extra care
- You arrived in or will leave Japan during the year.
- You have substantial foreign-source or separately taxed income.
- You are unsure whether you are a resident for Japanese tax.
- Your employer does not perform normal year-end adjustment.
- You expect to file for medical expenses or another deduction.
- Your donation receipt and official address do not match.
- You may not be subject to resident tax in the following year.
These cases do not automatically make Furusato Nozei unavailable, but they can make a standard ceiling unreliable. A licensed Japanese tax professional can assess your complete facts.
A simple checklist
- Confirm you expect Japanese income and resident-tax liability.
- Estimate the ceiling from your own income and deductions.
- Make the donation in your own name.
- Save Japanese-language receipts even if the portal has English UI.
- Complete One-Stop or a final return—never assume checkout is enough.
- Check the following year’s resident-tax notice.
