Japan – Taxation

How does the tax system in Japan work?

The body responsible for overseeing Japan’s tax system is the National Tax Agency (Kokuzeicho), commonly referred to as the NTA. Income tax is levied on earnings from the preceding calendar year — running from 1 January through 31 December — and applies at three levels: national, prefectural, and municipal. Because these tiers operate simultaneously, your total tax burden is the combined total of national income tax and local inhabitant taxes, a reality that demands careful attention when planning your finances ahead of a move.

Every person living in Japan, irrespective of nationality, is designated as either a resident or a non-resident for tax purposes. Within the resident category, Japanese tax law draws a further distinction between permanent residents and non-permanent (temporary) residents. The category into which you fall directly governs how broadly Japan’s tax reach extends to your income, making it one of the most consequential concepts to understand before you arrive.

An individual is treated as a non-resident for Japanese tax purposes unless they hold a domicile in Japan or have maintained continuous residence there for at least one year. Once that one-year threshold is crossed, a person becomes a “resident” and is then placed into one of two sub-categories — non-permanent resident or permanent resident — based on the cumulative length of their time in Japan.

A resident taxpayer is classified as a permanent resident if they are a Japanese national, or if they are a foreign national who has spent more than five of the preceding ten years in Japan in aggregate. Permanent residents face taxation on their entire worldwide income, whereas non-residents are liable only for income derived from Japanese sources.

This framework differs noticeably from systems such as those used in France or Germany, where tax residency hinges primarily on days spent in the country or the location of a person’s primary home, without any equivalent to Japan’s intermediate non-permanent resident category. Japan’s three-tier structure is a defining feature of its tax system and deserves thorough consideration when organising your personal finances.

Japan’s position is that if you maintain a home in Japan and are present there for more than 180 days annually, you are a tax resident — regardless of how often you travel abroad. For the most current definitions and thresholds, always refer to the NTA’s official website, since these rules can change.

Does Japan have double taxation agreements, and how do they affect expats?

Japan has entered into tax treaties with a wide range of countries with the aim of facilitating cross-border investment and commerce, eliminating situations where the same income is taxed twice, and curbing tax evasion and avoidance. Treaty provisions take precedence over domestic law, which means a treaty benefit can reduce or entirely remove a Japanese tax liability that would otherwise arise under standard national rules.

Japan’s treaty network currently encompasses 75 conventions applicable to 81 jurisdictions. The Ministry of Finance publishes and maintains a continuously updated list (last updated October 2025) covering Japan’s tax conventions, tax information exchange agreements, and related arrangements. The complete and current listing can be found on the Ministry of Finance’s official treaty page.

Tax treaties divide taxing rights between the two contracting states, reduce or eliminate withholding tax on cross-border payments such as dividends, interest, and royalties, and establish a pathway for resolving disputes when both countries seek to tax the same income. Many of these agreements have also been updated under the OECD’s Multilateral Instrument (MLI) to incorporate anti-avoidance provisions and improved dispute resolution mechanisms.

For non-residents who visit Japan briefly, most of Japan’s double tax agreements provide an exemption from Japanese taxation, subject to certain conditions — generally that the individual is present in Japan for no more than 183 days in any calendar year, that their remuneration is paid by an employer who is not a resident of Japan, and that their salary is not borne by a permanent establishment situated in Japan.

To access treaty benefits, you must file an Application Form for Income Tax Convention (Form 1) together with the relevant attachments with the Japanese tax authorities before the payment date. If you miss this deadline, it is still possible to recover overpaid withholding tax by submitting an Application Form for Refund of the Overpaid Withholding Tax (Form 11).

A foreign tax credit mechanism also exists, allowing residents to offset Japanese tax against tax already paid abroad on the same income, subject to a formulaic ceiling. Where a treaty does not fully resolve a double taxation dispute, the Mutual Agreement Procedure (MAP) enables Japan’s NTA and the counterpart authority in the other country to work towards a resolution. Always verify your country’s treaty status and the specific provisions that apply to your circumstances with the NTA or a qualified tax adviser before submitting your return.

What taxes do expats need to pay in Japan?

Foreign residents in Japan may be subject to a range of taxes. The most significant are national income tax, local inhabitant tax, and social insurance contributions. The following section explains each in turn.

National income tax

Japan structures its income tax across seven progressive brackets, so that tax paid as a proportion of income rises alongside earnings. National income tax rates run from 5% on the lowest band to 45% on earnings above the highest threshold (as of 2025). In addition, a Special Reconstruction Income Tax surtax of 2.1% is levied on top of the calculated national income tax figure through 2037, introduced following the devastation of the 2011 earthquake and tsunami.

Local inhabitant tax

Local inhabitant tax is charged at a combined flat rate of approximately 10% by Japan’s prefectural and municipal governments on a taxpayer’s income from the preceding year. It applies to anyone who is resident in Japan as of 1 January of the current year. A flat per-capita component is also assessed annually — the standard figure is JPY 5,000, though the precise amount can vary depending on your prefecture and municipality (as of 2024–25).

The one-year lag built into this tax catches many new arrivals by surprise: no inhabitant tax is owed during your first calendar year in Japan, but the following year’s bill reflects that initial year’s earnings. This stands in contrast to income tax models in many other countries — such as the UK’s PAYE system, which deducts income tax in real time — and has meaningful cash-flow implications that are worth factoring into your budget from the outset.

Capital gains tax

Proceeds from the disposal of listed shares in Japan are generally subject to a flat combined rate of approximately 20.315% (inclusive of the reconstruction surtax and inhabitant tax), while gains realised on the sale of real estate are taxed at progressive income tax rates that depend on how long the property was held. Property disposed of within five years of acquisition is treated as short-term; property held beyond that period is treated as long-term, with long-term gains generally attracting more favourable treatment. Rates are subject to legislative change, so always confirm the current position with the NTA.

Inheritance and gift tax

Anyone domiciled in Japan at the time an inheritance or gift is received is subject to Japanese inheritance and gift tax — regardless of the nationalities of the parties involved and regardless of whether the assets in question are located outside Japan. There is, however, an important exception for expatriates: if a non-permanent resident has been domiciled in Japan for an aggregate of ten years or less within the fifteen years preceding the inheritance, and has received assets located outside Japan from family members living abroad, only domestically situated assets are taxable. This is an intricate area of law, and specialist advice is strongly recommended for anyone with cross-border family wealth.

Property (fixed asset) tax

Fixed asset tax is an annual levy imposed on the owners of land, buildings, or depreciable business assets as at 1 January each year. The amount due is calculated by reference to the assessed fair current value of the asset and is payable to the municipal office in the area where the asset is located.

Social insurance contributions

Employee social insurance contributions typically include around 5% of salary for health insurance, 9.15% for pension, and 0.6% for unemployment insurance — giving a combined employee contribution rate of approximately 14.75%. Employers pay a broadly equivalent share of health and pension insurance costs (as of 2025). Japan has concluded social security agreements with a number of countries to prevent individuals from being enrolled in two countries’ social insurance systems simultaneously and to allow the totalisation of pension participation periods.

Consumption tax

Japan levies a consumption tax — comparable to VAT or GST in other jurisdictions — on most goods and services. The standard rate stands at 10% (as of 2025), with a reduced rate of 8% applicable to certain food products and non-alcoholic beverages. While not directly related to income, this tax is relevant to the overall cost of everyday life in Japan.

Are there any tax breaks or special regimes for expats in Japan?

Japan does not have a dedicated expat tax regime of the kind offered by, for example, Portugal’s former NHR programme or Italy’s inpatriate flat-tax scheme, which grant new arrivals preferential flat rates from day one. Instead, Japan’s concession to foreign nationals is built into the non-permanent resident classification, which functions as a transitional period of preferential treatment during the early years of residence.

Non-permanent resident status is Japan’s mechanism for easing foreign nationals into its tax system without immediately subjecting them to full worldwide taxation. If you are a non-Japanese national who has spent five years or fewer in Japan out of the preceding ten, your Japanese tax exposure is limited to income sourced within Japan and any foreign income that you physically bring into the country.

Because non-permanent residents would otherwise be taxable on foreign-source income as residents, the system taxes such income only when it is remitted to Japan — a framework sometimes described as “remittance basis” taxation. For those with foreign investment returns or offshore rental income that remains abroad, this can represent a substantial financial advantage, provided those funds are never transferred to a Japanese bank account.

This preferential treatment does, however, have a defined time limit. Once your cumulative presence in Japan exceeds five years within any rolling ten-year window, you transition to permanent resident status for tax purposes, at which point Japan taxes all income worldwide — including overseas rental income, dividends from foreign investment funds, and capital gains on the disposal of foreign assets.

For non-permanent residents, capital gains arising from the sale of shares listed on a foreign exchange qualify as foreign-source income and are therefore outside Japan’s tax reach unless the proceeds are remitted to Japan. Thoughtful management of where and when such proceeds are received can therefore generate meaningful tax savings during the non-permanent resident period.

The “Furusato Nozei” (hometown tax) scheme offers a further avenue for reducing tax liability. Under this arrangement, residents make donations to local governments and receive a credit against the following year’s inhabitant tax — and a portion of their national tax — beyond a ¥2,000 personal contribution, within applicable caps. The scheme is open to all residents, not specifically to expatriates, but it is a legitimate and widely used strategy for trimming the local tax bill while directing funds to regional communities.

Always consult the NTA’s English-language pages and a qualified Japanese tax professional (zeirishi) before acting on the non-permanent resident rules, since your individual circumstances and the interaction with your home country’s tax system may materially affect the outcome.

How and when do expats file a tax return in Japan?

Japan’s tax year spans 1 January to 31 December, and tax returns are ordinarily due to be filed between 16 February and 15 March of the year that follows. As an example, the return covering 2025 income must be submitted between 16 February and 16 March 2026. Because the precise filing window can shift slightly from one year to the next, always confirm the current deadline on the NTA’s official website.

Employees who are not required to file their own return will have income tax deducted directly from their wages by their employer throughout the year, with a formal reconciliation carried out at the time of the final salary payment. This outcome is broadly comparable to withholding arrangements in many other countries, though Japan’s employer-administered year-end adjustment (nenmatsu chosei) is a more comprehensive reconciliation process than its equivalent in many European systems.

The following steps set out the process for those who do need to file their own return:

1. Register your address: On arriving in Japan, register your residential address at your local municipal office (shiyakusho or kuyakusho). This enrols you in the local tax system and triggers the issue of your My Number — Japan’s individual tax identification number — which is required for all tax filings.
2. Gather income documentation: Assemble complete records of all income received during the calendar year, including payslips and salary statements, records of foreign income, investment or rental income documents, and any withholding tax certificates.
3. Calculate deductions: Your taxable income is your gross income minus a basic personal exemption, dependent exemptions where applicable, and allowable deductions including insurance premiums, qualifying medical expenses, and — for the self-employed — legitimate business costs.
4. Prepare your return: Japan’s digital filing platform, e-Tax, enables you to compile and submit your return online. In 2025, the NTA actively promoted smartphone filing and set 17 March 2025 as the deadline for 2024 returns. Paper returns remain an option and can be lodged at your local tax office (zeimusho) or sent by post.
5. File by the deadline: Those obliged to submit their own return — including self-employed individuals and others with complex income situations — must do so at their local tax office, by post, or through e-Tax between 16 February and 15 March of the year following the tax year.
6. Pay any tax due: Where income tax is not deducted at source by an employer, the full national income tax liability must be settled by 15 March of the following year (or by mid-April for those paying by automatic bank transfer), with two advance payments due in July and November of the tax year itself.
7. Pay local inhabitant tax separately: Foreign residents domiciled in Japan as of 1 January must pay inhabitant tax to their local municipality on the basis of the previous year’s income. For those in employment, the municipal authority notifies the employer of the amount owed, which is then deducted from salary in monthly instalments running from June through to May of the following year.

If you anticipate difficulties meeting a filing deadline or settling a tax bill, contact the NTA as early as possible. Filing late can attract penalties and interest. If your circumstances are at all complex — for instance, if you have foreign income, income from multiple sources, or have recently changed residency status — engaging a qualified tax adviser is strongly recommended. Expat-friendly tax professionals in Japan are available who work in English, Chinese, and other languages.

What are the tax implications of leaving Japan?

Departing Japan involves a number of tax-related steps that deserve careful attention both before and after you leave. Overlooking these can result in unexpected liabilities surfacing long after your departure.

Japan operates an exit tax that can apply to tax residents who hold certain financial assets at the time of departure. However, this exit tax does not apply to foreign expatriate employees unless the individual holds permanent residence status (Table 2 status) under the Immigration Control and Refugee Recognition Act. In practice, this means that most individuals on temporary visas and those with non-permanent resident classification will not be subject to exit tax on unrealised gains — but anyone who has acquired permanent residence status should seek professional advice well in advance of their planned departure date.

Leaving Japan does not automatically extinguish all Japanese tax obligations. If you later exercise stock options granted during your period of Japanese residence, or continue to receive rental income from property you still own in Japan, those amounts may remain subject to Japanese tax. These liabilities do not vanish simply because you have left the country.

If you are leaving your employment, ask your employer to deduct any outstanding tax liability in one payment from your final salary. If you are leaving Japan more broadly, you should either settle all unpaid taxes in a single lump sum before departure or appoint a tax agent (nozei kanrinin) who will handle payments on your behalf going forward, and notify your local tax office accordingly.

It is also worth noting that inhabitant tax can follow you abroad. Because this tax is based on your status as at 1 January of the relevant year — not on whether you are still physically present in Japan when the invoice arrives — you may receive a bill from the municipal office after you have left. Ignoring it is not a viable option, as the city office may pursue payment overseas.

When you leave, formally deregister your address (jūsho todoke) at your local municipal office. This is the official procedure for notifying the Japanese authorities that you are no longer resident and terminates your local tax registration. Retain copies of all filed returns and tax payment receipts for at least five to seven years after your departure, as the NTA has the power to audit returns covering prior periods.

Practical tips for managing taxes as an expat in Japan

• Keep a precise record of your days in Japan from arrival. Whether you are classified as a non-permanent or permanent resident hinges on the total time you have spent in Japan within a rolling ten-year window. Maintain a meticulous log of entry and exit dates — the difference between five years and a single day beyond that threshold can dramatically alter your worldwide tax exposure.
• Obtain your My Number without delay. My Number is Japan’s individual tax identification number, performing a function similar to a national insurance number or tax file number in other countries. You will need it to submit returns, open bank accounts, and access public services. Register at your local municipal office shortly after you arrive.
• Handle remittances with care during the non-permanent resident period. The National Tax Tribunal has ruled that once funds from abroad are remitted to Japan, tax applies even if those funds are subsequently sent back overseas. Think carefully before transferring foreign-sourced money into a Japanese account.
• Actively pursue any applicable treaty benefits. Japan and your country of residence may have a bilateral tax treaty that reduces or eliminates Japanese tax on certain categories of income, such as interest, dividends, royalties, or employment income. The terms differ from treaty to treaty, so review the specific agreement that covers your situation rather than relying on general assumptions.
• Take note of the CRS information exchange regime. The NTA has significantly stepped up enforcement activity against non-filers, particularly as the automatic exchange of financial account information under the Common Reporting Standard (CRS) gives it visibility over foreign accounts held by Japanese residents. Overseas bank accounts and investment holdings are not beyond the NTA’s reach.
• Take tax advice before completing any significant asset sale. Whether the transaction involves property, shares, or a business interest, the applicable tax treatment can vary considerably depending on your residency status and the nature of the asset. Consulting a professional before completing a deal — rather than afterwards — gives you the greatest scope to manage the outcome.
• Plan around the five-year residency milestone. If you are approaching five years of residence in Japan, seek advice on whether it makes more sense to depart before crossing that threshold or to remain and structure your finances for full worldwide taxation. The right answer depends on your personal financial position, and both courses of action can be appropriate in different circumstances.
• Engage a qualified Japanese tax professional (zeirishi). For anyone with even moderately complex circumstances, consulting a registered Japanese tax accountant is highly advisable. The financial cost of an error — potentially years of back tax on worldwide income together with penalties and interest — vastly outweighs the cost of professional guidance.

Frequently asked questions: taxation in Japan for expats

When do I become a tax resident in Japan?

You are treated as a tax resident in Japan once you hold a domicile there or have maintained continuous residence for at least one year. If you keep a home in Japan and are present there for more than 180 days annually, you are considered a tax resident even if you travel outside the country regularly. Residency is determined by the facts of your situation rather than by the category of visa you hold.

Does Japan tax my worldwide income?

The answer depends on your residency classification. Permanent residents are subject to Japanese tax on their total worldwide income, while non-residents are liable only for income originating from Japanese sources. If you are a non-Japanese national who has spent five years or fewer in Japan out of the preceding ten, your Japanese tax exposure covers only Japan-sourced income and any foreign income remitted to Japan. Once you exceed that five-year mark, you become a permanent resident for tax purposes and full worldwide taxation applies.

What is the income tax rate in Japan?

Japan applies national income tax across seven progressive brackets, with rates ranging from 5% at the lowest band to 45% on the highest band (as of 2025). A Special Reconstruction Income Tax surtax of 2.1% is charged on top of the calculated national income tax figure through 2037. Local inhabitant tax of approximately 10% is levied separately by your prefecture and municipality.

Do I need to file a tax return every year?

Employees who are not required to submit their own return will have income tax withheld from their wages by their employer throughout the year, with a final reconciliation carried out at year end. That said, if you have supplementary income, work for multiple employers, incur substantial medical expenses, or want to maximise your deductions, filing a return may reduce your liability or generate a refund. Self-employed individuals, freelancers, and those with significant foreign or investment income are generally required to file.

How is foreign pension income treated in Japan?

The taxability of a foreign pension in Japan depends on your residency category and the terms of any applicable double taxation agreement. Permanent residents must generally declare all foreign income on their Japanese return, whereas non-permanent residents are taxed on foreign pension income only to the extent it is remitted to Japan. Treaty provisions vary considerably — some agreements specifically exempt government pensions from Japanese tax. Review the relevant treaty for your specific pension type and seek advice from a tax professional.

What is the deadline for filing a Japanese tax return?

Those required to file must submit their return at their local tax office (zeimusho), by post, or via e-Tax between 16 February and 15 March of the year following the relevant tax year. For example, the return for 2025 income must be lodged between 16 February and 16 March 2026. Check the NTA’s official website each year to confirm any changes to the filing window.

Can I file my Japanese tax return online?

Japan’s e-Tax platform enables digital filing of tax returns. In 2025, the NTA actively promoted smartphone-based filing and confirmed 17 March 2025 as the deadline for 2024 returns. The e-Tax system is accessible through the NTA’s website and supports submissions from both desktop computers and smartphones. Certain supporting documents may still need to be provided in their original form, so consult the NTA’s guidance for the requirements specific to your circumstances.

Will I be taxed twice — once in Japan and once in my home country?

Japan has taken significant steps to address this risk through its network of bilateral tax treaties and its domestic foreign tax credit provisions. As of 2025, Japan has 75 tax conventions in force covering 81 jurisdictions. Where a treaty exists between Japan and your country, it will typically allow you to claim relief on income that would otherwise be taxed in both places. Where a treaty does not fully eliminate the double taxation, the Mutual Agreement Procedure (MAP) provides a mechanism through which Japan’s NTA and the other country’s tax authority can work together to resolve the dispute. Seek professional advice to ensure any available relief is claimed correctly and within the applicable time limits.
