# 手取り計算 — Japan net salary

Source page: https://valem.run/calculators/japan/net-salary

Your Japanese take-home is gross minus about 14.69% social insurance, national income tax and a 10% resident tax.

**Tax year:** 2026

## How it 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.
