What is the Japan Income Tax Calculator?
Japan's national income tax (所得税, shotokuzei) uses a progressive rate structure from 5% to 45% applied to taxable income. Employees benefit from a statutory employment income deduction (給与所得控除) that reduces gross salary before tax is applied. A 2.1% reconstruction surcharge (復興特別所得税) applies to all national income tax until 2037 to fund reconstruction after the 2011 Tōhoku earthquake.

Taxable Income = Gross Salary − Employment Deduction − Basic Deduction. National Tax = Progressive slab tax on taxable income. Total = National Tax × 1.021.- T_total

Frequently asked questions
What is the income tax rate in Japan in 2025?
Japan's national income tax uses progressive rates from 5% (up to ¥1.95M) to 45% (over ¥40M). A 2.1% reconstruction surcharge is added to the national tax. Combined with 10% residence tax, effective rates for high earners can reach 55%+.
What is the reconstruction surcharge in Japan?
The reconstruction surcharge (復興特別所得税) is an additional 2.1% of national income tax. It was introduced to fund reconstruction after the 2011 Great East Japan Earthquake and applies until December 2037.
How is employment income deduction calculated in Japan?
For salaries up to ¥8.5M, the employment income deduction (給与所得控除) reduces taxable income on a sliding scale — from ¥550,000 minimum for low earners to ¥1.95M for salaries around ¥8.5M. Above ¥8.5M the deduction is capped at ¥1.95M.
Do I pay residence tax on top of income tax?
Yes. Residence tax (住民税) is approximately 10% of taxable income and is levied by your prefecture and municipality. It is paid the following year on the previous year's income, so new residents face a one-year lag.
What deductions can reduce my Japanese income tax?
Common deductions include: basic deduction (¥480,000), employment income deduction, spouse deduction (up to ¥380,000), dependent deductions, social insurance premium deduction, life insurance deduction (up to ¥120,000), and iDeCo (individual defined contribution pension) contributions.
