Japan payroll runs on two parallel systems the employer must operate together: social insurance, a set of schemes covering health, pension, long-term care and unemployment with contributions split between employer and employee against capped wage bases, and income tax withheld at source with a year-end adjustment that settles most employees' liability without an individual return. Both are exacting about enrolment, monthly remittance and paperwork, and both assume a registered Japanese employer. The figures below are the employee-side rates as published in PwC's Japan summary at the time of writing; the employer funds its own shares on top, and nothing on this page is tax advice.
Social insurance: several schemes, each with its own cap
The employee-side deductions stack up scheme by scheme. Health insurance runs at 4.925% on the Tokyo rate, on a maximum of JPY 1,390,000 of wages per month, with a parallel cap for bonuses; welfare pension takes 9.15% on a maximum of JPY 650,000 of standard monthly remuneration; unemployment insurance takes 0.5% of salary and bonuses; and a child and childcare support levy adds 0.115% on the same capped base as health insurance. Long-term care insurance adds 0.81% for employees aged 40 to 64. PwC puts the combined employee-side rate at 14.69%. The caps matter for senior salaries, because above each ceiling that scheme's deduction stops growing, so the effective rate falls as pay rises past the caps.
The employer side, and why quotes must show it
The rates above are what comes out of the employee's pay; the employer remits its own contributions on top of gross salary for the same schemes, so the true cost of a Japanese hire is meaningfully above the gross figure on the offer letter. Rates are revised on a published schedule, health insurance varies by prefecture and insurer, and the standard remuneration bases are banded rather than continuous, so a credible payroll provider or EOR quote for Japan should show the current employer contribution stack line by line against the salary being offered rather than a single blended percentage. A quote that shows only the employee deductions is showing you the smaller half of the statutory cost.
Income tax: withholding at source and the year-end adjustment
Employers withhold income tax from salary at source each month, and the system is built so most employees never file: the year-end adjustment reconciles the year's withholding against the final liability, applying credits such as the special credit for housing loans. Per the National Tax Agency's guidance, a wage earner generally has no final return to file where total salary is JPY 20,000,000 or less, all wages come from a single payer with tax withheld at source, and other income for the year is JPY 200,000 or less. For the employer this makes December's adjustment run a real compliance event: collecting employees' declaration forms, recalculating the year and settling differences through the final payrolls of the year.
Entity, payroll provider or EOR in Japan
With a Japanese entity, a local payroll provider operates the machinery: enrolment in the insurance schemes, banded standard remuneration calculations, monthly withholding, and the year-end adjustment. Without an entity, a foreign company cannot register for these systems, so the compliant route to a Japanese hire is an employer of record whose local entity holds the employment contract and carries the enrolment, remittance and filing obligations as legal employer, invoicing salary plus employer costs plus a flat monthly fee. Japan's caps and banded bases make quotes unusually checkable: ask any vendor to show the calculation for your actual salary figure, and verify the rates against current published sources before relying on them.

Questions people ask about japan payroll
What comes out of an employee's salary in Japan?
Per PwC's summary: health insurance at 4.925% on capped wages (Tokyo rate), welfare pension at 9.15% on a capped base, unemployment insurance at 0.5%, a child and childcare levy of 0.115%, and long-term care at 0.81% for ages 40 to 64, a combined employee-side rate of 14.69%, plus income tax withheld at source.
Do employers pay social insurance on top of gross salary in Japan?
Yes. The employee-side rates are matched by employer contributions to the same schemes, remitted by the employer, so the full cost of employment sits well above gross salary. Ask for the employer stack itemised in any quote.
Do employees in Japan file tax returns?
Mostly not. The employer's year-end adjustment settles the liability; per the NTA, no final return is generally needed where salary is JPY 20,000,000 or less from a single withholding payer and other income is within JPY 200,000 for the year.
Can I employ someone in Japan without a Japanese entity?
Not directly, since enrolment in the tax and social insurance systems requires a registered local employer. An employer of record supplies one: its Japanese entity employs your hire and runs payroll, for a flat monthly fee on top of the employment costs.
