About the Furusato Nozei Calculator
Furusato Nozei lets you donate to Japanese municipalities and may include local gifts. Within your limit, everything above the ¥2,000 annual self-contribution is credited against income tax and residence tax. This calculator applies the statutory formula for the year you donate (2026 and 2027 donations are supported): your limit is the donation at which the special residence-tax credit reaches 20% of your residence tax income levy. For donations from 2027, the special credit is also capped at ¥1.93M. If you leave social insurance blank, it is estimated from FY2026 rates. Treat the result as a guide.
