About estimating Japanese income and take-home pay
How take-home pay is derived
For a salaried worker in Japan, take-home pay is what remains after social insurance contributions, income tax and resident tax are deducted from gross annual income — in that order, since each step depends on the previous one.
Gross income is first reduced by the employment income deduction to give employment income. Further deductions (basic, spouse, dependant, and the fully deductible social insurance premiums) yield taxable income. National income tax is then applied on a progressive scale, with the special reconstruction surtax added on top. Resident tax consists of an income-based portion and a flat per-capita portion, and is levied the following year based on the prior year's income.
Social insurance covers health insurance, pension (employees' pension for the employed, national pension otherwise) and employment insurance. Most of it is computed from standard remuneration and fixed rates, so it behaves differently from progressive income tax.
How to use this tool
Enter gross annual income, number of dependants and pension type to get income tax, resident tax, social insurance contributions and annual/monthly take-home pay, with a line-by-line breakdown covering the employment income deduction, individual deductions, taxable income and tax credits.
No sign-in is needed to run an estimate. Each run produces a shareable result link you can send to family or an adviser; signing in additionally lets you revisit your past estimates from the page.
Common uses
Comparing two offers in real terms — a gross gap of ¥500,000 does not translate into the same gap in take-home pay. Projecting monthly cash flow after a job change or raise. Checking how the burden shifts when moving to the national pension. Pinning down fixed deductions before drawing up a household budget.
Frequently asked questions
How is take-home pay calculated for an employee in Japan?
It is gross annual income minus social insurance contributions, income tax and resident tax, in that order. Because each step depends on the previous one, a ¥500,000 gap in gross pay does not mean a ¥500,000 gap in take-home pay. Enter your income, dependants and pension type to see the line-by-line breakdown.
Why does resident tax seem to lag a year behind income tax?
Resident tax has an income-based portion and a flat per-capita portion and is levied the following year on the prior year's income, so in the year your income changes the resident tax burden often has not shown up yet.
What does social insurance include?
Health insurance, pension and employment insurance. For pension it is the employees' pension if you are employed and the national pension otherwise. Most items are computed from standard remuneration and fixed rates rather than progressive rates.
Do I need to sign in, and can I share the result?
No sign-in is needed. Each estimate produces a shareable result link you can send to family or an adviser, and signing in lets you revisit past estimates.
Why might the result differ from my withholding slip?
The estimate uses general assumptions and does not cover special deductions, mortgage tax credit, side income or rate differences between municipalities. For actual figures, use your withholding slip and the tax notice from your municipality.
Estimates use general assumptions and do not cover every individual circumstance (special deductions, mortgage tax credit, side income and other income types, or rate differences between municipalities). For actual figures, refer to the withholding slip issued by your employer and the tax notice from your municipality.
