Taxes in Japan for Foreign Residents: Income Tax, Resident Tax, Filing and Leaving Japan

Taxes in Japan can be confusing because income tax and resident tax are handled by different authorities and often appear at different times. Salary withholding, year-end adjustment and a final tax return are also separate procedures.

Foreign nationality does not create one special tax category. Your Japanese tax treatment can depend on your tax residence, domicile, length and purpose of stay, income source, employment, overseas income, family deductions and any applicable tax treaty.

Quick Comparison: The Main Personal Taxes

Tax or procedure	Who administers it?	When it commonly appears
Income tax and special income tax for reconstruction	National Tax Agency and the responsible tax office	Withheld from salary or settled through year-end adjustment and final return
Individual resident tax	Prefecture and municipality	Generally calculated from prior-year income and collected during the following fiscal period
Consumption tax	National and local tax systems	Included in many purchases; separate filing rules may apply to businesses
Individual enterprise tax	Prefectural tax authority	May apply to qualifying self-employed business activities
Property and vehicle-related taxes	Local tax authorities	Apply when you own covered property or vehicles

This guide focuses on individual income tax and resident tax. Business owners, property investors and people with cross-border income may require professional advice.

Tax Residence Is Not the Same as Immigration Status

Your visa or status of residence does not by itself decide your Japanese income-tax classification. The National Tax Agency considers whether you have a domicile in Japan or have maintained a residence in Japan continuously for one year or more.

A person can be treated as a resident earlier than the one-year point when objective facts show that the person’s base of living is in Japan. The analysis can include housing, work, family and expected duration.

The main individual categories are:

Classification	General description	Why it matters
Non-resident	A person who does not meet Japan’s resident definition for income-tax purposes	Generally taxed under rules for Japanese-source income
Non-permanent resident	A resident without Japanese nationality who has had a domicile or residence in Japan for five years or less during the preceding ten years	Special scope rules can apply to certain foreign-source income and remittances
Resident other than a non-permanent resident	A resident who does not fall within the non-permanent-resident definition	Broader income-tax scope generally applies

Income Tax for Employees

Employers generally withhold income tax from salary payments. The amount deducted each month is an advance collection and may not equal the final annual tax.

Check each salary statement for:

• gross salary;
• taxable allowances;
• income tax withheld;
• Employees’ Pension contribution;
• health-insurance contribution;
• employment-insurance contribution;
• resident tax deducted;
• reimbursements that are not salary;
• year-to-date totals.

Keep the annual withholding slip, called a gensen chōshūhyō. You may need it for a final return, a new employer, a municipal procedure or proof of income.

What Is the Year-End Adjustment?

Most employees with straightforward salary income have annual income tax settled by the employer through the year-end adjustment, called nenmatsu chōsei.

The employer uses submitted declarations and supporting documents to recalculate the annual salary tax. The result may produce an additional deduction or a refund through payroll.

Documents may include:

• dependent and spouse declarations;
• insurance-premium certificates;
• National Pension payment certificates;
• housing-loan documents when applicable;
• documents concerning overseas dependent relatives;
• remittance documents for overseas relatives;
• information from a previous employer during the same year.

Missing the employer’s internal deadline does not automatically mean the deduction is permanently lost, but you may need to claim it through a final tax return.

When a Salary Employee May Need a Final Tax Return

Most salary earners whose tax is completed through year-end adjustment do not file a final return. However, a return may be required in situations identified by the National Tax Agency.

Common examples include:

• annual salary receipts exceeding ¥20,000,000;
• receiving salary from more than one payer under relevant conditions;
• income other than employment and retirement income exceeding ¥200,000 under the applicable salary-earner rule;
• receiving salary that was not subject to Japanese withholding;
• having business, freelance, property, investment or other taxable income;
• departing Japan without completing the necessary settlement;
• being specifically instructed to file by the tax authority.

The ¥200,000 salary-earner rule is not a universal tax-free allowance. Local resident-tax reporting may still be required, and different rules apply when the salary conditions are not met.

What Is Kakutei Shinkoku?

Kakutei shinkoku is the final income-tax return procedure. The taxpayer calculates annual income, deductions, credits, tax withheld and the final balance.

In principle, a required return is filed between February 16 and March 15 of the following year. When a deadline falls on a weekend or holiday, the annual schedule may differ. Always check the current National Tax Agency guide.

Filing methods may include:

• e-Tax;
• forms prepared with the National Tax Agency return-creation system;
• submission to the responsible tax office;
• postal submission under the current rules;
• professional filing through a licensed tax accountant.

Refund Returns

You may be able to file a return to claim a refund even when you were not required to file.

Examples can include:

• leaving a job before year-end adjustment;
• excess salary withholding;
• qualifying medical expenses;
• eligible donations;
• the first applicable year of a housing-loan credit;
• unclaimed social-insurance deductions;
• eligible casualty losses;
• other deductions or credits not reflected in payroll.

The National Tax Agency states that a refund return can generally be submitted for up to five years beginning January 1 of the year following the relevant tax year.

Documents to Keep for a Final Return

Record	Why you may need it
Salary withholding slips	Shows salary, deductions and income tax withheld
Freelance invoices and payment records	Supports business or miscellaneous income calculations
Expense receipts	Supports deductible expenses when legally allowed
Pension and health-insurance certificates	Supports social-insurance-premium deductions
Medical receipts and reimbursement records	Needed when calculating a medical-expense deduction
Donation certificates	Supports qualifying donation deductions or credits
Overseas tax statements	May be needed for foreign-income and foreign-tax-credit analysis
Family-relationship and remittance documents	May be required for deductions involving overseas relatives
Bank statements	Helps reconcile income, remittances and payments

A Japanese bank account can simplify tax payments and refunds. See our bank-account guide for foreign residents.

Freelance, Side-Job and Remote-Work Income

Do not assume that money paid by an overseas client or deposited into a foreign account is automatically outside Japanese taxation.

Tax treatment can depend on:

• your Japanese tax-residence classification;
• where the work was physically performed;
• the source and type of income;
• whether you operate a business;
• whether expenses are legally deductible;
• whether foreign tax was paid;
• whether a tax treaty applies;
• whether funds were remitted to Japan under non-permanent-resident rules.

Keep contracts, invoices, exchange-rate calculations and proof of foreign tax. Cross-border remote work is exactly where guesswork gets expensive.

Overseas Income and Tax Treaties

Tax treaties can change withholding or taxation for particular income and residence situations. A treaty does not simply exempt every foreign national from Japanese tax.

Confirm:

• which country is your treaty residence;
• whether a tie-breaker rule is relevant;
• which article covers the income;
• whether a treaty notification must be submitted before payment;
• whether Japanese filing is still required;
• whether foreign tax credit is available;
• which documents prove foreign tax payment.

Use the treaty text and current National Tax Agency procedure for the actual income type.

Overseas Dependent Relatives

Claiming a deduction for a relative living outside Japan can require relationship documents and remittance documents. Additional conditions apply to certain relatives aged 30 through 69.

Prepare early:

• official documents proving the family relationship;
• Japanese translations where required;
• bank or transfer records showing support payments;
• student documents where relevant;
• disability documentation where relevant;
• proof that the current income and age conditions are met.

Cash allegedly handed over without a reliable record can be difficult to prove.

Resident Tax Is Separate From Income Tax

Individual resident tax is a local tax generally consisting of prefectural and municipal components. Filing or paying national income tax does not mean resident tax has disappeared.

As a general municipal rule, resident tax is imposed on people registered in the municipality on January 1, regardless of nationality, based mainly on income from the previous year.

The January 1 Rule

The municipality responsible for resident tax is generally determined by your address on January 1.

This means:

• moving in February does not usually transfer that year’s assessment to the new municipality;
• a bill from your former municipality may be correct;
• leaving Japan after January 1 may not erase the year’s resident-tax obligation;
• address registration errors can cause notices to go to the wrong place.

Our resident-registration guide explains municipal address procedures.

How Resident Tax Is Collected

Collection method	How it works	What to watch
Special collection	The employer deducts resident tax from salary and pays the municipality	A job change can interrupt or change the collection schedule
Ordinary collection	The municipality sends payment slips or supports another direct payment method	You must pay each installment yourself
Lump-sum salary collection after leaving a job	Remaining resident tax may be deducted from final salary when conditions and procedures allow	Confirm the amount before assuming your final salary is wrong

Payment methods differ by municipality. They may include bank payment, convenience-store slips, account transfer, smartphone payment or supported online services.

When You Change Jobs

Income tax, resident tax, health insurance and pension can all change at the same time, but they are separate records.

Ask the old and new employers:

• whether year-end adjustment will be completed;
• when the withholding slip will be issued;
• whether resident-tax special collection continues;
• whether remaining resident tax will be deducted from final salary;
• which pension and insurance dates were reported;
• which documents the new employer needs.

See our National Pension guide and National Health Insurance guide when employment coverage ends.

My Number and Tax Procedures

My Number is used in legally specified tax and social-security procedures. Employers, financial institutions and tax authorities may request it for an authorized purpose.

Use a secure submission method. Do not casually send a photograph of the back of the card through an unverified messaging account.

Our My Number guide explains the number, notice, card and privacy checks.

Leaving Japan: Income Tax

Leaving Japan can change your tax residence and create an early filing requirement.

The National Tax Agency explains two main paths:

1. Appoint a tax agent in Japan and file by the normal statutory deadline.
2. When no tax agent is appointed, file the required return and pay the tax before departure.

A tax agent can be an eligible person residing in Japan or a Japanese corporation. The official notification must be submitted to the responsible tax office.

Leaving Japan: Resident Tax

Resident tax requires a separate check with the municipality. If you were registered there on January 1, tax may still be assessed even when you leave Japan later in the year.

Before departure, ask:

• whether the current year is fully assessed;
• whether additional bills will be issued after departure;
• whether a local tax representative is required;
• whether the employer will deduct the remaining balance;
• whether you can pay the total amount before leaving;
• where notices and refund documents will be sent.

Do not rely on an income-tax agent automatically handling resident tax. Confirm the national and local appointments separately.

Common Mistakes

Thinking visa status decides tax residence

Immigration status and tax residence use different legal tests.

Thinking salary withholding always finishes everything

Multiple employers, side income and deductions can create a filing requirement or refund opportunity.

Using the ¥200,000 rule as a universal exemption

The rule applies only under specific income-tax conditions and does not automatically remove resident-tax reporting.

Forgetting resident tax because no bill arrived in the first year

Resident tax generally follows the prior year’s income, so collection is delayed.

Throwing away the withholding slip

It is one of the most important annual tax documents for an employee.

Claiming overseas dependents without remittance proof

Current deductions may require both relationship and financial-support documents.

Leaving Japan without a tax plan

Income tax and resident tax require separate departure checks.

Keep Final Utility Bills When Moving or Leaving Japan

Final bills help document service periods, moving dates and outstanding payments when closing your Japanese residence. Read our electricity, gas and water setup guide for foreign residents.

Keep Tax Records From Your First Month in Japan

Tax questions often appear later than the move itself. Keep salary statements, withholding documents, municipal notices and payment records from the beginning rather than trying to reconstruct them before filing or departure.

Practical rule:
Income tax and resident tax use different systems and timing. A lack of an immediate bill does not prove that no later payment or procedure will apply.
