Basics of take-home pay

Take-home pay is your gross annual salary minus income tax, resident tax and social insurance. As of 2025 a typical employee keeps about 75%–80% of gross; the higher the salary, the lower the take-home ratio because of progressive taxation.

How income tax is calculated

Income tax is progressive, from 5% on taxable income up to ¥1.95M to 45% above ¥40M across seven brackets. Taxable income = salary − employment income deduction − basic deduction (¥480,000) − other deductions.
