FAQ

What is take-home pay?
It is the amount you actually receive after deducting income tax, resident tax, and social insurance from your gross salary.
How is take-home pay calculated?
Gross income is reduced by employment income deduction, then income tax, resident tax, and social insurance are calculated and subtracted.
What is the take-home for 4M JPY annual income?
For no dependents, under 40: approximately 3.27M JPY/year (about 273K/month). Use the tool for detailed calculations based on your conditions.
How is social insurance calculated?
Health insurance (prefecture rate) + pension (9.15%) + employment ins. (0.55%) + nursing ins. (40+, ~0.80%). All are employee's half of the total rate.
Does furusato nozei increase take-home?
Furusato nozei is a donation so it reduces take-home, but you receive gifts worth up to 30% of the donation for just 2,000 JPY out-of-pocket.
Does iDeCo increase take-home?
Yes. iDeCo contributions are fully tax-deductible, reducing both income tax and resident tax, effectively increasing take-home pay.
What are the income walls?
Thresholds where taxes or social insurance increase significantly, reducing net pay. Key walls: 1.03M, 1.30M, 1.78M (new in 2026), and 2.01M JPY.
How does the 2026 tax reform affect take-home?
Basic deduction increased from 480K to 580K JPY, increasing net pay for those earning up to 8.5M. The income wall was also raised to 1.78M.
How does spouse deduction work?
If spouse earns under 1.03M, a 380K deduction applies, reducing taxes. From 1.03M to 2.01M, a special spouse deduction (gradually decreasing) applies.
