Types of Taxes You May Pay in Japan

Foreign residents typically encounter:

• Income Tax (Shotokuzei)
• Resident Tax (Juminzei)
• Social Insurance Contributions

If you are enrolled in public systems, you may also pay:

• National Health Insurance
• National Pension

Income Tax (National Tax)

Income tax is deducted from your salary each month if you are employed.

How It Works

• Progressive tax rates (higher income = higher rate)
• Withheld automatically by your employer
• Adjusted during year-end tax adjustment (Nenmatsu Chosei)

If you are self-employed, you must file a tax return yourself.

You will need your My Number when filing.

Resident Tax (Local Tax)

Resident tax is based on your previous year’s income.

Important points:

• Paid starting from your second year in Japan
• Billed by your local municipality
• Paid via salary deduction or payment slips

Your registered address determines which municipality collects it.
Make sure your Address Registration is always updated.

Tax Rates Overview

Income tax (national):

• 5% to 45% depending on income bracket

Resident tax:

• Generally around 10% of taxable income

Exact amounts depend on income, deductions, and family status.

Year-End Tax Adjustment (For Employees)

If you are employed full-time, your company usually handles tax adjustment in December.

You may need to submit:

• Insurance payment certificates
• Dependent information
• Housing loan documents (if applicable)

---

Filing a Tax Return (Kakutei Shinkoku)

You must file a tax return if you:

• Are self-employed
• Have multiple income sources
• Earn over certain thresholds
• Want to claim additional deductions

Returns are usually filed between February and March.

You can submit online using the National Tax Agency’s e-Tax system.

Common Tax Deductions

You may qualify for deductions such as:

• Social insurance premiums
• Medical expenses
• Dependent spouse or children
• Life insurance payments

If you send money to family abroad, special documentation may be required.

What Happens If You Do Not Pay?

Failure to pay taxes may result in:

• Late penalties
• Interest charges
• Difficulty renewing visas
• Issues when applying for permanent residency

Tax compliance is important for long-term stay in Japan.

---

Tax and Bank Payments

Many taxes are paid via:

• Automatic withdrawal from your Bank Account
• Payment slips at convenience stores

Setting up automatic payments reduces the risk of missing deadlines.

---

Do Foreigners Pay the Same Tax as Japanese Citizens?

In general, yes.

However, Japan has tax treaties with many countries to prevent double taxation.
If you have overseas income, consult a licensed tax professional.

Important Notes
