Resident Tax & Income Tax for Foreigners in Japan

If you've recently moved to Japan, you may have heard the phrase resident tax in Japan and wondered what it means, how much it costs, and whether it applies to you. You're not alone — resident tax confuses many foreign residents, especially in the first year or two. This guide explains the basics clearly, so you know what to expect and how to prepare.

What Is Resident Tax in Japan?

Resident tax (住民税, jūminzei) is a local tax paid to your municipality — your city, town, or ward. It funds local public services like waste collection, parks, schools, and community infrastructure. Almost everyone who lives in Japan, including foreign residents, is required to pay it if they meet the income threshold.

Resident tax is separate from national income tax (所得税, shotokuzei), which goes to the central government. As a foreign resident, you will likely deal with both.

Who Has to Pay Resident Tax in Japan?

If you were registered at a Japanese address on January 1st of a given year and earned income in the previous year above the local exemption threshold, you are generally required to pay resident tax. This applies regardless of nationality — if you have a residence card and are registered in Japan, the rule applies to you.

Key points to understand:

• Resident tax is based on the previous year's income. The tax you pay in 2025 is calculated on income you earned in 2024.
• The exact exemption threshold varies by municipality, but it is typically quite low. Confirm the specific threshold with your local city or ward office.
• Part-time workers, full-time employees, freelancers, and business owners may all be liable.
• Students on a student visa may be exempt in some cases — check with your local office.

How Is Resident Tax Calculated?

Resident tax in Japan generally has two components:

These are general figures. Rates can vary slightly by location and may change, so always confirm the current rates with your local municipal office or on the official government website (soumu.go.jp).

The First Year Surprise — Why New Residents Often Get a Big Bill

One of the most common shocks for new foreign residents is receiving a large resident tax bill in their second year in Japan. Here's why:

• In your first year of living in Japan, you generally pay no resident tax — because it is based on the previous year's income, and you had no Japanese income yet.
• In your second year, you receive a bill based on everything you earned in year one. If you had a full year of income, this can feel like a large unexpected expense.

Knowing this in advance means you can set money aside. Many experienced foreign residents recommend saving a portion of your monthly income specifically for this future bill.

How and When Do You Pay Resident Tax?

If you are a company employee, your employer will usually deduct resident tax automatically from your salary each month (called special collection, 特別徴収). You don't need to do much — just check your payslip.

If you are self-employed, freelance, or your employer does not handle this, you will receive payment slips (納税通知書) from your municipality, usually in June. You can pay:

• In four installments throughout the year (June, August, October, and January)
• At a convenience store (konbini), bank, or post office using the provided slips
• Via bank transfer or online payment, depending on your municipality

What About Income Tax (National Tax)?

Income tax is filed separately through the annual tax return process (確定申告, kakutei shinkoku), which takes place each year roughly from mid-February to mid-March at your local tax office (税務署, zeimusho). Company employees usually have their income tax handled by their employer through year-end adjustment (年末調整), so they may not need to file themselves — but freelancers and those with multiple income sources typically must file.

Filing your tax return correctly is also important because it feeds into your resident tax calculation for the following year.

Documents You May Need

• My Number card (マイナンバーカード) or My Number notification letter
• Residence card (在留カード)
• Withholding tax slips (源泉徴収票) from your employer
• Bank account details for refunds, if applicable
• Receipts for deductible expenses (medical costs, social insurance premiums, etc.)

Document requirements can vary. Always confirm what is needed at your local tax office or municipality before your appointment.

Practical Tips for Foreign Residents

• Register your address promptly. Your resident tax obligations are tied to your address registration (住民登録). Make sure you register at your local city or ward office as soon as you move.
• Don't ignore tax notices. Letters from the municipality about taxes are important. If you're unsure what a letter says, ask a Japanese-speaking colleague or contact your ward office — many now offer multilingual support.
• If you leave Japan mid-year, you may still owe resident tax. Arrange payment before leaving or appoint a tax administrator (納税管理人).
• Keep your income documents — pay slips, receipts, and employer certificates — organized throughout the year. It makes tax season much easier.

Summary: Resident Tax in Japan for Foreign Residents

Resident tax in Japan can feel overwhelming at first, but once you understand how it works, it becomes much more manageable. To recap the key points:

• Resident tax is a local tax paid to your city or ward, based on your previous year's income.
• It applies to foreign residents who were registered in Japan on January 1st and earned income above the exemption threshold.
• Employees usually have it deducted automatically; self-employed people pay in installments using slips received in June.
• Expect a larger-than-usual bill in your second year — and plan for it by setting savings aside.
• Income tax (national) and resident tax (local) are separate obligations — both matter.

Taxes can feel daunting in a foreign language, but Japan's system is structured and predictable once you know the rules. Take it one step at a time, use your local ward office's multilingual support where available, and don't hesitate to ask questions. You've got this.
