How 手取り (take-home pay) in Japan is calculated
Japanese payroll deducts social insurance — health, pension and employment — around 14.69% of gross for 2026: pension 9.15%, health 4.925% (Tokyo kyokai kenpo), employment insurance 0.5%, and the new child-care support levy of 0.115% that started in April 2026. National income tax then applies on brackets from 5% to 45% after the employment-income and basic deductions.
Resident tax of about 10% is charged on the prior year's income, which is the most common source of confusion. This simplified model applies both. Estimate, not tax advice.

Frequently asked questions
What is the social insurance on a Japanese salary?
Health, pension and employment insurance, about 14.69% of gross together in 2026 — the rise comes from the new child-care support levy introduced in April.
Why is resident tax on last year's income?
Resident tax is assessed on the prior year, so a new earner pays little in year one and more the next.
Is this exact?
It is a simplified estimate; the deduction reform makes the exact figure prefecture-specific.
