How residence tax is calculated

Rounding, the tax-free limit and the adjustment credit
  • Taxable income is rounded down to ¥1,000. The prefecture and city income levies are each rounded down to ¥100.
  • The tax-free limit grows with your spouse and dependents, children under 16 included. For the per capita levy, it also depends on your city’s grade (1 to 3).
  • The adjustment credit is 5% of a base of at least ¥50,000. With a spouse or dependents the base is larger, mainly at taxable income up to ¥2 million.
  • Tax from June 2026 (on 2025 income): the single, grade 1 limit is a salary of ¥1,100,000.

When you pay residence tax, and the first year

Residence tax is charged by the city you live in on January 1, on your income for the previous calendar year. You pay it from June to the next May.

Your employer usually deducts it in 12 payments from June to May. Otherwise you pay it in 4 installments: June, August, October and January. In your first year of work in Japan, there is usually none. If you move within Japan, you keep paying the January 1 city for that year.

Leaving Japan or your job

If you lived in Japan on January 1, you owe that year’s residence tax, even if you leave in spring.

Frequently asked questions

How much is residence tax in Japan?
At the standard rates, about 10% of last year’s taxable income plus ¥5,000 a year. On a ¥5,000,000 salary with ¥723,132 of social insurance and no dependents, it is ¥243,000 for June 2027 to May 2028.
Why did I pay no residence tax in my first year in Japan?
Residence tax is charged on the previous year’s income to people living in Japan on January 1. With no income in Japan last year, there is nothing to tax yet. It usually starts in June of your second year.
Do I have to pay residence tax if I leave Japan?
Yes, if you lived in Japan on January 1, you owe that fiscal year’s residence tax. If you leave your job between January 1 and April 30, your employer deducts the rest from your last pay when it is enough.
What is the difference between residence tax and income tax in Japan?
Income tax is national and charged on this year’s pay. Residence tax goes to your prefecture and city and is charged on last year’s income. Its deductions are smaller: the basic deduction is ¥430,000.
When will I know my residence tax amount?
Your city normally sends the amount to your employer by May 31, and your employer passes the notice to you. If you pay it yourself, the city sends you a tax notice at least 10 days before payment is due.
