Japan tax residency explained for newcomers

What Is Tax Residency in Japan?

Tax residency in Japan is different from immigration residency. Even if you have a valid visa and live in Japan, your tax obligations depend on whether the Japanese tax authority considers you a tax resident. Generally, you become a tax resident if you stay in Japan for more than one year continuously, or if you have a permanent home available to you there. Once you're classified as a tax resident, you must pay income tax on all worldwide income earned while you're in Japan.

How Japan Classifies Tax Residents

Japan divides people into three categories for tax purposes:

• Permanent residents: Japanese citizens or those with permanent residency status
• Non-permanent residents: Foreigners who have lived in Japan for 5 consecutive years or plan to stay for over one year
• Non-residents: People with visas shorter than one year or temporary visitors

Your classification affects which income is taxable. Non-permanent residents and non-residents may have different rules about what foreign income they must declare.

Income You Must Report

As a tax resident, you typically need to report:

• Salary and wages from Japanese employers
• Business income from self-employment or freelance work
• Income from rental properties in Japan
• Investment income (dividends, interest)
• Foreign income, depending on your residency classification

Non-residents usually only pay tax on income earned in Japan, while permanent and non-permanent residents may owe tax on worldwide income.

Filing Your Taxes

Most employees have taxes deducted automatically through payroll. However, you may still need to file a tax return if you:

• Are self-employed or freelance
• Have multiple income sources
• Earned income that wasn't taxed automatically
• Want to claim deductions or credits

The tax filing deadline is typically in spring each year. Your local tax office can provide the exact date and help you understand what forms you need.

Getting Help With Tax Compliance

New residents should:

• Register at your local municipal office (ward office) immediately after arriving
• Contact your city's tax office to understand your specific obligations
• Keep records of all income and expenses
• Ask about tax agreements between Japan and your home country, which may prevent double taxation
• Consider hiring a tax accountant (called a "tax accountant" or professional) if your situation is complicated

Starting the Process

Visit your local municipal government office's tax section or the National Tax Agency website to confirm current filing requirements and deadlines. Rules can change, and getting accurate information from official sources is essential to staying compliant.
