Tax Guide
Learn how taxes work in Japan
Japan's tax system consists of several layers. As a resident, you are subject to national income tax, a reconstruction surtax (supporting recovery from the 2011 earthquake), resident tax (prefectural and municipal), and social insurance premiums.
The fiscal year for individual taxes runs from January 1 to December 31. Employees have taxes withheld at source, while self-employed individuals must file a final tax return (確定申告) between February 16 and March 15 of the following year.
Income tax uses a progressive bracket system with rates from 5% to 45%. Resident tax is a flat 10% (plus a per-capita levy of approximately ¥5,000).
The tax treatment differs significantly depending on your employment status:
| Category | Employee (給与所得者) | Self-Employed (個人事業主) |
|---|---|---|
| Income Deduction | Employment income deduction (automatic) | Business expenses (actual or blue return) |
| Social Insurance | Shakai Hoken (company shares half) | National Health Insurance + National Pension (full amount) |
| Business Tax | N/A | 3-5% on income above ¥2.9M |
| Tax Filing | Year-end adjustment by employer | Self-filing required (確定申告) |
| Consumption Tax | N/A | Required if registered for Invoice System or revenue above ¥10M |
The Blue Return (青色申告) system allows self-employed individuals to claim special deductions in exchange for maintaining proper bookkeeping. There are three tiers:
- e-Filing with double-entry bookkeeping (¥650,000): The highest deduction. Requires submitting your return electronically and maintaining full double-entry books.
- Standard double-entry (¥550,000): Same bookkeeping requirements, but filing on paper instead of electronically.
- Simplified bookkeeping (¥100,000): A smaller deduction for those who maintain simpler records.
You must apply for Blue Return status by March 15 of the fiscal year (or within 2 months of starting your business if new). The application form is available from the NTA.
Japan has two main social insurance systems:
- Shakai Hoken (社会保険): For employees. Includes health insurance (健康保険) and employees' pension (厚生年金). Premiums are split roughly 50/50 with your employer. Also includes employment insurance (雇用保険).
- National Health Insurance + National Pension: For self-employed, freelancers, and those not covered by Shakai Hoken. NHI premiums vary by municipality and are based on income. National Pension is a flat monthly amount (¥16,980/month in FY2026).
All social insurance premiums are fully deductible from your taxable income.
Those aged 40-64 also pay a long-term care insurance premium (介護保険料) added to their health insurance.
- Furusato Nozei (ふるさと納税): Donate to local governments in exchange for gifts and a tax credit. Effectively, you redirect part of your resident tax while receiving local products. Learn more
- Medical Expense Deduction (医療費控除): Deduct medical expenses exceeding ¥100,000 (or 5% of income if lower). Includes dental, prescription costs, and transportation to hospitals.
- Mortgage Deduction (住宅ローン控除): A tax credit of up to 0.7% of your outstanding mortgage balance for up to 13 years on a new home. NTA details
- iDeCo (個人型確定拠出年金): Contributions to Japan's individual defined contribution pension are fully deductible. Employees can contribute up to ¥23,000/month; self-employed up to ¥68,000/month. Official iDeCo site
- Life/Earthquake Insurance Deductions: Premiums for life insurance and earthquake insurance policies qualify for small deductions (up to ¥50,000 and ¥50,000 respectively).
