In this guide, we’ll break down the structure of residence tax, eligibility requirements, payment methods, and key updates you need to know. Whether you’re an expat settling into life in Japan or a local exploring tax deductions, this is your go-to resource.

What Is Residence Tax?

Residence tax, or "住民税" (jūminzei), is a cornerstone of Japan’s local taxation system, directly funding public services such as education, infrastructure, and emergency services. It is split into two main components:

1. Prefectural Tax (dōfukenminzei) - Managed by the prefectural government.
2. Municipal Tax (shichōsonminzei) - Managed by the city, town, or village you reside in.

Each component serves a distinct purpose. Prefectural taxes often contribute to regional infrastructure projects like highways or disaster prevention systems, while municipal taxes are used for local needs such as public schools, waste management, and community centers.

Why It Matters

Unlike income tax, which supports national programs, residence tax ensures that local governments have the funding necessary to maintain the quality of life in your immediate surroundings. This system exemplifies Japan's emphasis on localized governance, empowering smaller municipalities to address unique community needs.

Who Pays Residence Tax?

Residence tax is a geographically rooted tax. It is levied on anyone registered as a resident of Japan as of January 1st of the current year. This principle has practical implications, especially for those planning to relocate:

• If you move from Tokyo to Osaka on January 2nd, you will still owe residence tax to Tokyo for the entire year. Osaka will start collecting your residence tax only the following year.

Case Study: An Expat's Move

Take, for example, John, an IT professional who earned ¥6 million in 2024 and relocated from Yokohama to Kyoto on February 1st, 2025. Despite living in Kyoto for most of the year, his 2025 residence tax (based on 2024 income) is paid to Yokohama. Understanding this rule can help individuals plan their finances and avoid surprises.

How Is Residence Tax Calculated?

Calculating residence tax involves a structured process that ensures fairness while providing opportunities for deductions. Let’s dive deeper into the key elements:

Income Deductions

Just like income tax, residence tax provides several deductions to help reduce your taxable income:

Deduction Type	Details
Basic Deduction	¥430,000 for most taxpayers
Spousal Deduction	Up to ¥380,000 if your spouse's income falls below ¥1.03 million
Dependent Deduction	Varies based on the age of dependents; ¥330,000 per child under 16
Social Insurance Premium Deduction	Covers mandatory contributions such as health insurance and pension
Medical Expense Deduction	Available for out-of-pocket medical expenses exceeding 5% of your annual income

Example Calculation
Let’s consider Hana, a freelancer earning ¥4 million annually, with ¥500,000 in social insurance payments and ¥100,000 in eligible medical expenses. After deductions, her taxable income might look like this:

• Total Income: ¥4,000,000
• Deductions: ¥600,000 (insurance + medical expenses)
• Taxable Income: ¥3,400,000
  Her residence tax would then be calculated at 10% of ¥3,400,000 (¥340,000) plus the per capita rate of ¥5,000.

Recent Changes: FY2024 Tax Reform

Japan’s fiscal year 2024 tax reform introduced significant changes to make the tax system more equitable and supportive of low- to middle-income households. Here’s what you need to know:

Flat-Rate Tax Reduction

A ¥10,000 tax reduction applies to residence tax, benefiting taxpayers with an annual income of ¥18.05 million or less. This reform directly impacts families by extending the same reduction to each dependent.

Contextual Insight

This policy is part of a broader trend toward easing the financial burden on households amid rising living costs. Japan has also implemented similar measures for income tax, signaling a focus on tax relief as a means of boosting domestic spending and economic resilience.

Flexible Payment Options

Japan offers multiple payment channels for residence tax, reflecting the country’s tech-savvy yet pragmatic approach to public services.

Convenience Store Payments

Convenience stores such as 7-Eleven and Lawson allow you to pay residence tax bills quickly, often with no additional fees. Simply bring the payment slip and settle the bill at the register—a popular method among busy professionals.

Smartphone Payment Apps

Apps like PayPay and LINE Pay have gained traction, allowing residents to scan a QR code on their tax bill and pay in seconds. For example, in 2022, over 20% of taxpayers in metropolitan areas utilized smartphone payment apps for their tax obligations.

Bank Transfers and Credit Cards

While bank transfers remain the traditional option, municipalities are increasingly adopting online portals for credit card payments. Be mindful, though—credit card payments may incur a handling fee of 1–2%, depending on your municipality.

Furusato Nozei: A Unique Tax Strategy

The Furusato Nozei (hometown tax donation) program has emerged as a popular way to reduce residence tax while supporting rural communities. The system allows individuals to donate to a municipality of their choice in exchange for:

• Tax Deductions: Up to 30% of your donation amount.
• Local Gifts: Thank-you items like wagyu beef, seafood, or artisanal goods.

Example

An employee earning ¥8 million annually donates ¥50,000 through Furusato Nozei. They receive a deduction of ¥48,000 from their residence and income tax (¥50,000 donation - ¥2,000 administrative fee) and a gift of premium Hokkaido melons.

Trend

In 2023, over ¥700 billion was donated via Furusato Nozei, underscoring its popularity among urban residents looking to give back to rural areas.
