Millions of Americans think about moving to Japan 🇯🇵 every year, either for work, study, or just to experience life in a new country. But when it comes to US taxes, things might not be as simple as packing your bags. Many people wonder: “If I move to Japan, do I still have to file US taxes?” This guide breaks down everything you need to know in a way that’s easy to follow—so you can spend less time being confused about taxes and more time enjoying your new life.

Most Popular Questions

1. Do I have to file US taxes if I live in Japan?

Yes, if you are a US citizen or Green Card holder, you must file US taxes even if you live in Japan 🇯🇵. The United States 🇺🇸 is one of the few countries in the world that taxes based on citizenship, not just where you live. This means your worldwide income—money you earn everywhere—must be reported to the US government, no matter where you move.

2. What counts as “worldwide income”?

Worldwide income means all the money you earn in a year, no matter where it comes from. For example:
– Your salary from a job in Japan 🇯🇵
– Money from freelance work online
– Rental income from a property in the United States 🇺🇸
– Dividends from both US and Japanese companies

Everything counts, and it all needs to go on your US tax return using Form 1040.

US Tax Filing Requirements for Expats in Japan

3. What tax forms must I file with the United States 🇺🇸 if I live in Japan 🇯🇵?

Most people will need to file these forms:
– Form 1040: This is the main US individual income tax return. You use it to report all the money you earned during the year, no matter where it came from. You can find the official Form 1040 here.
– Form 2555: This form lets you exclude up to $130,000 of foreign-earned income (for tax year 2025) from your US taxes if you meet certain rules about living outside the United States 🇺🇸.
– Form 1116: If you paid taxes to Japan 🇯🇵, this form can help you get a tax credit so you don’t pay tax on the same money twice—once in Japan 🇯🇵 and once in the United States 🇺🇸.
– FBAR (FinCEN Form 114): If all your non-US bank accounts add up to more than $10,000 at any point during the year, you must file this form to let the US government know.
– FATCA (Form 8938): If your combined foreign financial assets are over $200,000 (or $400,000 for couples), you need to file this form to report those assets.

4. What happens if I forget to file or file late?

If you don’t file your US taxes, you might get fines or even lose your passport in some cases. The US government takes these rules seriously, even for expats living in Japan 🇯🇵. It’s important to file on time every year.

5. Do I still have to pay US taxes if I pay taxes in Japan 🇯🇵?

Sometimes, yes—but usually, you won’t have to pay taxes twice on the same income. Thanks to tax treaties and special rules, you can often use credits or exclusions so you don’t get taxed in both countries. For example, if you pay income tax in Japan 🇯🇵, you can often claim a “Foreign Tax Credit” or use the “Foreign Earned Income Exclusion” for US taxes.

Japanese Tax Filing Basics

6. Do I have to file taxes in Japan 🇯🇵 too?

Most US citizens who live and work in Japan 🇯🇵 must also file taxes there. If you live in Japan 🇯🇵 for more than a year, you usually become a “resident” for tax purposes. That means you pay Japanese tax on your income.

7. What if my employer in Japan 🇯🇵 already withholds taxes from my paycheck?

If all your income comes from your Japanese job and your company withholds tax for you, you might not need to file a Japanese tax return. But, if you have other types of income—like freelance work, business earnings, or very high income—you still might need to file a Japanese return.

8. How do Japanese taxes and US taxes interact?

Both countries want to tax you, but the US-Japan tax treaty and special IRS rules help make sure you don’t have to pay tax twice on the same money. Most expats file both returns, but only pay extra if the tax in one country is higher than the other.

How Do US Expats in Japan 🇯🇵 Avoid Double Taxation?

9. What is the US-Japan tax treaty?

This treaty is an agreement between the two countries. It makes sure people who pay tax in one country are not taxed again in the other on the same income. It also decides which country gets to tax certain types of income.

10. What is the Foreign Earned Income Exclusion (FEIE)?

FEIE is a rule that lets you “exclude” (remove) up to $130,000 (for the 2025 tax year) of money you make from working abroad from your US taxable income. To use it, you must meet either the “Physical Presence Test” (you spent at least 330 days in another country in a 12-month period) or the “Bona Fide Residence Test” (you are a true, long-term resident of Japan 🇯🇵).

11. How does the Foreign Tax Credit work?

If you pay income tax in Japan 🇯🇵, you can get a credit for those taxes on your US return using Form 1116. This credit lowers your US tax bill so you don’t pay double on the same income.

FBAR and FATCA: Other Big Reporting Rules

12. What is FBAR and who needs to file it?

The Foreign Bank Account Report (FBAR) must be filed by people who have a total of more than $10,000 in all their foreign (non-US) bank and financial accounts at any time during the year. This isn’t a tax, but it’s a rule to help stop illegal money hiding. You file the FBAR online using the FinCEN Form 114.

13. What is FATCA and what does Form 8938 do?

FATCA stands for the Foreign Account Tax Compliance Act. If the value of your foreign financial assets goes over certain amounts ($200,000 for singles or $400,000 for married couples filing together), you have to file Form 8938 with your US tax return. This form reports your foreign assets, like bank accounts, investments, and some retirement plans.

14. What counts as a “foreign financial asset”?

• Foreign bank accounts
• Stocks or securities issued by a non-US company
• Foreign partnership interests
• Options or derivatives from overseas

If you are not sure, ask a tax preparer with experience working with US expats in Japan 🇯🇵.

More Common Questions and Actions

15. If I am a student or temporary worker in Japan 🇯🇵, do I still need to file US taxes?

Yes. Even if you are a student (such as on an exchange program), or on a temporary assignment, you are still required to file US taxes if your income is above the filing threshold. The rules for reporting are the same.

16. Do Green Card holders have to file US taxes while living in Japan 🇯🇵?

Yes. If you hold a US Green Card, you must file US tax returns every year, even if you move to another country like Japan 🇯🇵.

17. What is the deadline for filing US taxes from Japan 🇯🇵?

Normally, US tax returns are due by April 15th. If you’re living abroad on that date, you get an automatic two-month extension—to June 15th. But, if you owe any tax, the money is still due by April 15th to avoid extra interest.

18. Can I file my US taxes online from Japan 🇯🇵?

Yes. Many online services allow US citizens abroad to file their taxes electronically, and some specialize in helping expats. The official IRS website has more information for taxpayers living outside the United States 🇺🇸.

19. What if I have never filed US taxes but have lived in Japan 🇯🇵 for years?

You can usually catch up using an IRS program called the Streamlined Filing Compliance Procedures. This helps expats get back on track without big fines if they did not know about the rules. Always get advice from a qualified tax professional if you’re behind.

Sample Scenario for US Taxes in Japan 🇯🇵

Imagine Anna, a US citizen, took a job in Tokyo. She earns $75,000 a year from her Japanese employer, and has a small savings account in Japan 🇯🇵 with $15,000 in it. Here’s what she must do:
– File Form 1040 with the IRS every year.
– Since her income is under the FEIE limit, file Form 2555 to exclude all $75,000 from US taxable income.
– If her employer in Japan 🇯🇵 withholds all her required Japanese tax, she may not owe the United States 🇺🇸 any extra tax. But she must still file.
– She must file FBAR because her Japanese bank account balance was over $10,000.
– She does not need to file Form 8938 because her total foreign assets are under $200,000.
– Anna also needs to make sure she follows any Japanese tax rules.
