Japan Tax Calculator

Income tax (calculated)

Employment-income deduction (minimum ¥740,000 in 2026), income-tiered basic deduction (¥1,040,000 when total income is ¥4.89 million or less), progressive national tax, and 2.1% reconstruction surtax. Taxable income is rounded down to ¥1,000. Monthly take-home is the annual estimate ÷ 12, not a payslip.

Insurance & pension (estimated)

Employees: 5% health, 9.15% employees’ pension, 0.50% unemployment (FY2026 general), plus 0.80% nursing care if age 40–64. This is a Tokyo-area kyokai kenpo style estimate; standard monthly remuneration grades are not modeled. Employer contributions are extra and not subtracted from take-home.

Freelancers: National Health Insurance ≈ 10% of this year’s profit, or ¥50,000 in the first year (municipal rates often sit between about 6% and 10%+). National Pension is ¥17,920 per month (¥215,040/year) for FY2026 if the checkbox is on.

Resident tax (estimated)

Charged if you were a resident of Japan on 1 January. We treat “first year in Japan” as ¥0. Otherwise: 10% of (income − resident basic deduction ¥430,000 − social insurance), rounded down to ¥1,000, plus ¥5,000 per-capita tax and ¥1,000 forest environmental tax. The income-tax basic deduction is different and is not used here. This year’s payment often relates to last year’s income; the figure is a same-year planning combination.

Special-credit ceiling: ¥2,000 + (income levy × 20%) ÷ (90% − your income-tax rate × 1.021), rounded down. This is not a guarantee of a ¥2,000 out-of-pocket result. Mortgage credits and other donations can lower the room.
