GUIDE TO UNDERSTANDING JAPANESE PAYSLIPS: GROSS VS. NET SALARY AND DEDUCTIONS
1. WHY IS MY TAKE-HOME PAY LOWER? BASIC STRUCTURE OF "GROSS" AND "NET"
A Japanese payslip (Kyuyo Meisai) generally consists of three main blocks: "Payments" (money paid by the company), "Deductions" (money taken out), and "Attendance" (hours worked).
GROSS SALARY (GAKUMEN)
The gross salary is the total amount the company pays you. This includes your base salary plus overtime pay, position allowances, and commuting allowances (transportation fees). The amount stated in job postings or employment contracts usually refers to this "gross" figure.
NET SALARY (TEDORI)
The net salary is the actual amount deposited into your bank account after social insurance and taxes are deducted. In Japan, companies use a "withholding tax" (Gensen Choshu) system where they calculate and pay taxes on your behalf. Generally, your net pay is about 75% to 80% of your gross salary.
THE "TRANSPORTATION FEE" MISCONCEPTION
Commuting allowances are included in the gross salary but are generally tax-free up to a certain limit. However, note that a higher total gross pay (including high transportation fees) may increase your "Standard Monthly Remuneration" rank, which slightly raises your social insurance premiums.
2. THE REALITY OF DEDUCTIONS: SOCIAL INSURANCE AND TAXES
The "Deductions" (Kojo) section is often the most confusing for foreigners. It consists of two main categories: Social Insurance and Taxes.
THE FOUR TYPES OF SOCIAL INSURANCE
HEALTH INSURANCE: Covers 70% of medical costs when you visit a hospital. Premiums are split 50/50 between the employer and employee.
WELFARE PENSION (KOSEI NENKIN): Contributions for your future retirement. Also split 50/50. If you leave Japan, you can claim a "Lump-sum Withdrawal Payment" using your payslips and pension book.
EMPLOYMENT INSURANCE: Provides benefits if you lose your job. While the premium is small, it is a vital safety net for visa renewals and job hunting.
NURSING CARE INSURANCE: Only paid by those aged 40 and older. It will not appear on the payslips of younger workers.
THE TWO TYPES OF TAXES
INCOME TAX: A national tax calculated based on your monthly earnings. The monthly deduction is an estimate; the exact annual amount is finalized during the "Year-end Adjustment" (Nenmatsu Chosei) in December.
INHABITANT TAX (RESIDENT TAX): This is the most important point. This tax is based on your previous year's income. Therefore, most foreigners do not pay it in their first year but see a sudden deduction starting from June of their second year.
PRO TIP: THE IMPORTANCE OF DEPENDENT DEDUCTIONS
If you send money to family members in your home country, you may qualify for "Dependent Deductions" to reduce your taxes. Ensure you submit "Relationship Documents" and "Remittance Records" to your company to avoid losing tens of thousands of yen annually.
3. ARE YOU BEING PAID CORRECTLY? ATTENDANCE AND OVERTIME RULES
The "Attendance" (Kintei) section is the foundation of your pay. If these numbers are wrong, your salary will be incorrect regardless of the calculation logic.
OVERTIME PAY RATES
Under Japanese Labor Law, work exceeding 8 hours a day or 40 hours a week requires a premium of at least 25%.
Late-night Overtime (22:00–05:00): Additional 25% (Total 50% premium)
Holiday Work (Legal Holidays): 35% premium or more If your payslip shows 20 hours of overtime but the amount is just "hourly rate x 20," it may be a legal violation.
THE TRAP OF FIXED OVERTIME PAY (MINASHI ZANGYO)
If your contract includes "Fixed Overtime," it means a certain number of hours (e.g., 20 hours) are pre-included in your base salary. However, any work exceeding those 20 hours must be paid extra. It is a mistake to believe you get the same salary regardless of how many hours you work.
PAID LEAVE (PAID VACATION)
Payslips often display your remaining paid leave days. Ensure that no "Absence Deductions" (Kekkin Kojo) are made for days you took as official paid leave.
4. SELF-CHECK ACTIONS TO PREVENT SALARY TROUBLES
Follow these three steps every month to protect yourself.
STEP 1: VERIFY THE NET PAY
Ensure the amount in your bankbook matches the "Net Pay" (Sashihiki Shikyugaku) on the bottom right of your payslip to the exact yen.
STEP 2: CHECK FOR SUDDEN CHANGES IN DEDUCTIONS
Social insurance premiums are adjusted based on your average pay from April to June. Be wary of unexplained deductions like "Social Club Fees" or mysterious administrative charges.
STEP 3: REVIEW THE YEAR-END ADJUSTMENT
In December or January, check your "Refund" (Kanhukin) or any additional tax collected. Keep your "Withholding Tax Certificate" (Gensen Choshu Hyo) safe, as it is mandatory for visa renewals.
5. CONCLUSION: YOUR PAYSLIP IS A "CREDIT SCORE" IN JAPAN
In Japan, a payslip is more than just a record of payment. It is proof that you are a law-abiding taxpayer and member of the social insurance system—essentially your "Trust Score." This record is strictly reviewed when applying for Permanent Residency. If you find an error, talk to your company's HR or accounting department first. If there is a language barrier, consider consulting multilingual support desks like "Job get JAPAN" or the Labor Standards Inspection Office.
