Salary and Take-Home Pay in Japan: Deductions, Allowances and Your Payslip

Gross pay vs take-home pay

Gross pay (額面 or 総支給額) is everything the company pays you for the month: base salary plus allowances and overtime. Take-home pay (手取り) is what remains after deductions. Job ads usually show a monthly base salary (月給) or an annual figure (年収), sometimes with fixed overtime already included, so read the details carefully.

Be careful with ads that say 固定残業代 or みなし残業 (fixed overtime pay). This means part of the monthly amount is prepaid overtime for a set number of hours. The ad should state how many hours it covers and how much of the pay it is. If you work more than those hours, the extra overtime should be paid on top.

When comparing offers, compare the same thing: base salary, what allowances are included, whether overtime is separate, how many bonuses there are and whether they are guaranteed. A higher monthly figure with fixed overtime and no bonus can end up lower than a modest salary with full overtime pay and bonuses.

What is deducted, and why

Income tax (所得税) is withheld from each pay packet by your employer, based on a table set by the National Tax Agency. Because the monthly amount is an estimate, the employer recalculates it at the end of the year in the year-end adjustment (年末調整), and you may get a small refund or pay a little more. If you have two jobs, or other income, you may need to file a tax return (確定申告) yourself.

Resident tax (住民税) is a local tax paid to your city and prefecture. It is calculated on the previous year's income, so in your first year in Japan you usually pay little or none, and it starts to be deducted from salary in your second year, typically from around June. People who leave Japan still owe resident tax for the year's assessment, so plan for it before you go.

Social insurance is the other big block. If you work enough hours at an enrolled company, you join the employer's health insurance (健康保険) and the Employees' Pension Insurance (厚生年金). Premiums are shared between you and the employer. Employees in a certain age range also pay long-term care insurance (介護保険) together with health insurance. Employment insurance (雇用保険) is a smaller deduction that funds unemployment benefits and training support.

• 所得税: national income tax, withheld monthly and settled in 年末調整
• 住民税: local tax based on last year's income, usually from your second year
• 健康保険: health insurance, covers most medical costs
• 厚生年金: employees' pension, also gives disability and survivors' cover
• 雇用保険: employment insurance, for unemployment and training benefits
• 介護保険: long-term care insurance, only above a certain age

Allowances: transport and others

Most companies pay a commuting allowance (通勤手当), often based on the cost of a commuter pass for the most reasonable route. It is not a legal obligation, so check the job ad and your contract. Within a limit set by tax rules, commuting allowance is not taxed, but it is counted in the pay used to calculate social insurance premiums.

Other common allowances include housing (住宅手当), family (家族手当), qualification or language allowances (資格手当), and shift or night allowances. Each company decides its own. Some allowances count toward overtime pay calculations and some do not, which is another reason to read your contract.

Always report your real address and commuting route to HR. Claiming an allowance for a route you do not use can be treated as misconduct.

Overtime, late-night and holiday pay

Under the Labour Standards Act, work beyond the legal working hours is overtime, and the company must pay a premium on top of your normal hourly rate. A company can only ask for overtime if it has a labour-management agreement (the so-called 36 agreement, 36協定) filed with the labour standards office, and there are legal upper limits on overtime.

Separate premiums apply to late-night work (深夜労働, roughly late evening to early morning) and to work on statutory days off (法定休日). When conditions overlap, such as overtime that runs into late night, the premiums are combined. The exact rates are set by law and can be checked on the Ministry of Health, Labour and Welfare website.

Keep your own record of the hours you work. If overtime is not paid, or you are told that overtime is included when it is not written in your contract, you can consult the labour standards inspection office (労働基準監督署) free of charge.

Bonuses

Many full-time jobs pay bonuses (賞与 or ボーナス), traditionally in summer and winter. They are not required by law. Whether and how much is paid depends on the company's rules and often on company results and your evaluation, so a job ad that says 賞与年2回 describes the usual practice, not a promise of a fixed amount.

Income tax and social insurance premiums are also deducted from bonuses, so the amount you receive is smaller than the headline figure. Resident tax is generally not deducted from bonuses, because it is spread across monthly salary.

Contract and dispatch roles often have no bonus, or pay a smaller one. When comparing annual income, check whether the annual figure in the ad includes bonuses.

How to read your payslip (給与明細)

Japanese payslips usually have three blocks. 勤怠 (attendance) shows days worked, paid leave used, overtime hours and late-night hours. 支給 (payments) lists base salary, each allowance and overtime pay, with the total at 総支給額. 控除 (deductions) lists health insurance, pension, employment insurance, income tax and resident tax. The bottom line, 差引支給額, is your take-home pay.

Check each payslip against your own records. Overtime hours should match what you worked, and deductions for social insurance should appear if you were enrolled. If a line is missing or looks wrong, ask HR politely; payroll mistakes do happen and are easier to fix early.

Keep your payslips and the annual withholding statement (源泉徴収票) you receive at the end of the year or when you leave a company. You may need them for tax returns, for proving income and for residence procedures such as renewal or change of status.

• 基本給: base salary
• 時間外手当 / 残業手当: overtime pay
• 通勤手当: commuting allowance
• 健康保険料 / 厚生年金保険料 / 雇用保険料: social insurance premiums
• 所得税 / 住民税: income tax / resident tax
• 差引支給額: net pay transferred to your account

Leaving Japan: the pension lump-sum withdrawal

Foreign nationals who have paid into the Japanese pension system and leave Japan without qualifying for a pension may be able to claim the Lump-sum Withdrawal Payment (脱退一時金). You apply to the Japan Pension Service after you leave Japan, and the claim has to be made within a set period. The minimum contribution period, the calculation and the deadline are published on the Japan Pension Service website.

For the Employees' Pension part, income tax is withheld from the payment. Some people can get part of that tax back by appointing a tax representative in Japan before leaving and filing a return; the National Tax Agency explains the procedure.

Think before you claim. Once you receive the lump sum, the contribution periods it covers are no longer counted toward a Japanese pension. If you may return to Japan, or your home country has a social security agreement with Japan that lets periods be combined, it can be better not to claim. Check with the Japan Pension Service if you are unsure.
