This calculator estimates your Japan annual income tax for individuals (most common: employees/salaried workers). You’ll need your annual gross salary, social insurance premiums paid, and (if relevant) spouse/dependents and other deductions. Japan’s national income tax is calculated on taxable income after deductions, using the progressive rate table, and includes the Reconstruction Special Income Tax (2.1% of income tax). Many residents also pay resident tax, commonly approximated as 10% of taxable income plus a per-capita levy (often about ¥5,000/year including the Forest Environment Tax). Verified January 28, 2026. Informational estimate only—official bills can differ due to municipal rules, credits, and precise rounding.

FAQs

Do I pay Japanese income tax if I’m a non-resident?

Yes—salary from Japan sources is commonly withheld at 20.42% in a simplified approach.

Why is my employment income lower than my gross salary?

Japan uses a statutory employment income deduction table rather than actual job expenses.

What’s the difference between income and taxable income?

Taxable income is total income minus deductions, rounded down to the nearest ¥1,000.

What is the Reconstruction Special Income Tax?

It’s an additional tax through 2037, calculated as 2.1% of base income tax (rounded down to ¥1).

How do spouse deductions work?

If your spouse meets the income conditions, a spouse deduction applies (higher for elderly spouses), and can reduce if your total income is high.

Which dependent gives the biggest deduction?

A specific dependent (typically age 19–22) gives ¥630,000, higher than general dependents.

Does this include resident tax?

Optionally. Resident tax is often approximated as 10% of taxable income plus a per-capita levy.

Why might my result differ from my official bill?

Differences can come from credits, separate taxation categories, municipal rules, and official rounding.
