Understanding Japan Income Tax 2025-26
Japan uses a progressive tax system where your income is taxed at different rates depending on your tax bracket. The National Tax Agency (NTA) administers the tax system. Additionally, all employees pay mandatory social insurance contributions (health insurance, pension, unemployment insurance), and some are subject to long-term care insurance. Local resident taxes are also applied.
2025 Tax Brackets (Updated for Tax Reform)
The 2025 tax reform brings important changes to Japan's tax system. The following are the income tax brackets effective for the 2025 tax year:
• 10% on ¥1,950,001 to ¥3,300,000
• 20% on ¥3,300,001 to ¥6,950,000
• 23% on ¥6,950,001 to ¥9,000,000
• 33% on ¥9,000,001 to ¥18,000,000
• 40% on ¥18,000,001 to ¥40,000,000
• 45% on income over ¥40,000,000
Updated Basic Deduction (2025 Tax Reform)
The 2025 tax reform significantly increased the basic deduction. For those with total annual income of ¥23.5 million or less, the basic deduction increased from ¥480,000 to ¥580,000. Additionally, special temporary deductions apply in 2025-2026:
Basic deduction increased from ¥480,000 to ¥580,000 for those with total income under ¥23.5 million
Temporary Special Deduction (2025-2026 only):
• Income ≤ ¥1.32M: Additional ¥370,000 (total ¥950,000)
• Income ¥1.32M - ¥3.36M: Additional ¥300,000 (total ¥880,000)
• Income ¥3.36M - ¥4.89M: Additional ¥100,000 (total ¥680,000)
• Income ¥4.89M - ¥6.55M: Additional ¥50,000 (total ¥630,000)
• Income over ¥6.55M: Permanent ¥580,000
Formula: \( \text{Taxable Income} = \text{Gross Income} - \text{Basic Deduction} - \text{Employment Income Deduction} \)
Employment Income Deduction 2025
Employees receive an employment income deduction, which is calculated based on salary income level:
• Salary ¥1,625,001 to ¥1,800,000: Deduction = ¥650,000
• Salary over ¥1,800,000: Deduction = Salary - ¥1,150,000 (maximum ¥2,200,000)
2025 Increase for Lower Earners:
Those earning less than ¥1,900,000 receive an additional deduction, resulting in tax savings of approximately ¥5,000 annually

All employees pay mandatory social insurance contributions. The following rates apply from April 2025:
Tokyo: 4.955% | Osaka: 4.72% | Kanagawa: 4.77%
Applied on monthly salary up to ¥1,390,000 maximum

\( \text{Total Social Insurance} = \text{(Health + Pension + Unemployment)} \)
\( + \text{Long-term Care Insurance (if applicable)} \)
\( \text{Maximum Applied on: } ¥650,000 \text{ monthly for pension; } ¥1,390,000 \text{ for health} \)
Resident Tax
Japan's resident tax (住民税) consists of prefectural and municipal taxes. The standard combined rate is approximately 10% of taxable income (5% prefectural + 5% municipal). Some prefectures have slightly different rates.
Applied on: Taxable income after national deductions
Formula: \( \text{Resident Tax} = \text{Taxable Income} \times 0.10 \)
Note: Resident tax is typically collected through payroll deduction starting the month after salary is paid.
Take-Home Pay Calculation Method
Your net income or take-home pay is calculated by subtracting all deductions from your gross salary:
Where:
• Gross Salary = Your total annual income
• Income Tax = Tax based on progressive brackets after deductions
• Social Insurance = Health, pension, unemployment, long-term care insurance
• Resident Tax = Approximately 10% of taxable income
Effective Tax Rate
Your effective tax rate is your total tax and contributions divided by your gross income. This is lower than your marginal tax rate (the rate applied to your last dollar of income) due to the progressive nature of the Japanese tax system:
\( \text{Marginal Tax Rate} = \text{Income Tax Rate at Your Bracket} + \text{Resident Tax Rate (10%)} \)
