FEIE vs Foreign Tax Credit in Japan: Which One Saves Americans More?

Every spring, Americans in Japan face the same decision on their US return: exclude their Japanese salary with the Foreign Earned Income Exclusion, or claim a credit for the Japanese tax already taken from their pay. Choose badly and you can lose child tax credit refunds or retirement contribution room, or end up stuck with a method that no longer fits. This guide explains both options in plain terms, works through realistic Japan-based scenarios, and shows you how to pick the one that actually saves you money.

Why Americans in Japan Face This Choice at All

My first US return from Japan was filed from a cramped 1K apartment in Saitama, with a stack of Japanese paperwork I could barely read. The question that bothered me was simple: I already paid tax in Japan, so why did the IRS still want a return from me? The answer is that the United States taxes by citizenship, not residence. Japan has nothing like this, so most of your Japanese coworkers will never understand why you spend a weekend every year on a second country’s tax forms.

Citizenship-Based Taxation Meets Japan’s Tax System

As a US citizen or green card holder, you report your worldwide income to the IRS every year, wherever you live. Moving to Japan and paying Japanese income tax and residence tax does not end that obligation. The US-Japan tax treaty also includes a “savings clause,” which lets the US keep taxing its own citizens as though the treaty mostly did not apply to them. For the full treaty picture, see The US-Japan Tax Treaty: How Americans Avoid Being Taxed Twice.

Congress knew this system would produce double taxation, so it built two main relief tools into the tax code: the Foreign Earned Income Exclusion, usually called the FEIE, and the Foreign Tax Credit, usually called the FTC. In most cases either one can bring your US tax on Japanese wages down to zero or close to it. They work very differently, though, and the effects reach well beyond your basic tax bill.

Here is the scene I have watched play out at countless expat dinners in Roppongi and Umeda. Someone says, “I just take the exclusion, everyone does.” Someone else says, “My accountant told me the credit is better in Japan.” Both may be right for their own household. The right answer depends on your income level, your family, whether you have investment income, whether you are self-employed, and how long you expect to stay in Japan.

What the Foreign Earned Income Exclusion Actually Does

The FEIE lets you subtract foreign earned income from your US taxable income, up to an annual maximum. That maximum is $132,900 per qualifying person for tax year 2026, up from $130,000 for 2025. The amount is per person, so if you and your American spouse both earn salaries in Japan, each of you can exclude up to the limit on your own earnings.

“Earned” is the important word. Earned income means pay for personal services: your salary from a Japanese company, your summer and winter bonuses, allowances from your employer, and net self-employment earnings from work done in Japan. It does not include interest, dividends, capital gains, rental income, or pension distributions. Those stay fully reportable no matter which method you choose.

To use the FEIE you have to qualify under one of two tests. The bona fide residence test asks whether you have actually made a life in Japan: an uninterrupted residence covering a full tax year, a residence card, a lease, a Japanese job. The physical presence test simply counts the days you spend outside the United States within a qualifying window. Most long-term residents with a work visa and a Japanese employer qualify under bona fide residence without much trouble. For a detailed walkthrough, read Form 2555 Walkthrough for Japan Residents: Bona Fide vs Physical Presence.

If you rent in Tokyo or another expensive area, the FEIE also lets you claim the foreign housing exclusion on the same form, which can shield part of your housing costs above a base amount. Tokyo has its own higher limit, and Foreign Housing Exclusion for Tokyo: How Much Rent You Can Actually Deduct explains how it works.

What the Foreign Tax Credit Actually Does

The FTC takes a different approach. You report all your Japanese income on your US return, calculate the US tax on it, and then subtract the income taxes you paid to Japan, dollar for dollar, up to a limit. Your Japanese national income tax counts, and so does your local residence tax (juminzei), which is generally treated as a creditable foreign income tax.

The FTC has one hard rule that people constantly get wrong. The foreign tax credit can only reduce US tax on foreign-source income. It cannot reduce US tax on US-source income, such as dividends from US stocks. If you hold an index fund in a US brokerage account and receive dividends, the US tax on those dividends stays, however much Japanese tax you paid on your salary.

The credit is also capped at the US tax attributable to your foreign-source income, and it is calculated in separate categories, or “baskets.” Wages go in the general category and most investment income goes in the passive category. Japan’s combined national and local income taxes often equal or exceed what the US would charge on the same wages, so many Americans here end up with more foreign tax paid than US tax to offset. Those unused credits do not disappear. They can be carried back and forward to other tax years, which matters a great deal if you later move somewhere with lower taxes or return to the US. Carryover and Carryback of Foreign Tax Credits: Multi-Year Planning From Japan covers the strategy, and Form 1116 for Japan: Turning Japanese Income Tax Into a US Credit covers the mechanics of the form.

Side-by-Side Comparison of FEIE and FTC for Japan Residents

Before we get into scenarios, it helps to put the two methods next to each other. I have watched people choose the FEIE purely because it sounds simpler. That simplicity is a little deceptive, because what you give up only shows up later.

The Comparison Table

Note that self-employment tax gets a “No” in both columns. Neither method reduces it, and the only effective fix for self-employed Americans in Japan comes from a completely different source, covered below.

Income the FEIE Cannot Touch

Many Americans in Japan assume the FEIE is a blanket “my Japan income is tax-free” button. It is not. It applies only to earned income up to the annual limit, and everything else stays exposed.

Take Mark, an American software developer in Fukuoka who is a composite of several people I know. He excludes his entire salary with the FEIE and assumes he is finished. He also has a brokerage account back home that pays quarterly dividends, a savings account at a Japanese bank that earns a little interest, and a small one-room apartment in Osaka that he rents out. None of that is earned income. All of it is reported in full. Because the dividends come from US companies, the US tax on them cannot be offset by the FTC either. Mark’s “zero tax” plan produces a bill he did not expect.

The stacking rule is the second trap. When you exclude income with the FEIE, whatever income remains is taxed at the rates that would apply if the excluded income were still included. Excluded wages effectively fill the lowest brackets, and your leftover investment income or above-limit salary gets taxed starting from higher brackets. This catches a lot of people off guard, especially the first year they receive a large bonus.

Japanese investment accounts are a third issue. Many Americans open NISA accounts at Japanese brokerages and buy Japanese mutual funds, which can create a separate and painful reporting problem regardless of which relief method you use. Before you invest locally, read Is Your NISA a PFIC? Why Japanese Investment Accounts Create US Tax Problems.

Where the FTC Hits Its Limits

The FTC is usually the stronger tool in Japan, but it has real limits.

First, the US-source income restriction. Dividends from US stocks, interest from a US bank, and gains on US real estate are US-source, and no amount of Japanese tax can be credited against the US tax on them. This is a statutory limit, not a technicality.

Second, the basket system. Excess credits in the general category, which is where Japanese wage tax goes, cannot be used to offset US tax on passive income. Suppose your Japanese salary generated far more creditable tax than you need, and you also have foreign dividend income in the passive category. You cannot freely shift the extra credit over to cover the dividends. The categories are calculated separately.

Third, timing. Japanese residence tax is assessed on the prior year’s income and billed during the following year, while national income tax is mostly withheld from your monthly pay. If you claim credits only on taxes actually paid during the year, the residence tax on one year’s income appears on a different year’s return. That gets messy in your first and last years in Japan. Many Americans elect to claim credits on an accrual basis so that the taxes line up with the income they relate to. Once made, that election generally sticks, so it is worth getting right from the start. For background on how that bill arrives, see Understanding Residence Tax in Japan: What It Is and How to Pay.

Fourth, and the one I most want you to remember: the FTC is limited to US income tax, meaning your regular tax liability. It does not reduce self-employment tax, including the Medicare portion, which is a separate tax calculated on Schedule SE.

Real-Life Scenarios: Which Method Wins

These scenarios are illustrative. They show the logic of the decision, not tax outcomes you can copy. Your actual numbers will depend on exchange rates, deductions, family status, and the details of your Japanese tax filings.

Scenario One: The Eikaiwa Teacher With a Young Family

Sarah teaches English at a conversation school in Nagoya. Her salary is modest and well below the FEIE limit. Her husband is Japanese and does not work outside the home, and they have two small children, both US citizens with Social Security numbers.

On the surface the FEIE looks like the obvious choice. Her entire salary is excludable, her US income tax drops to zero, and the form is fairly simple. Many teachers stop there.

The problem is that claiming the FEIE makes her ineligible for the refundable portion of the child tax credit. With two qualifying children, that refundable amount can mean real cash back from the IRS each year, money that can cover school supplies, a trip home, or a buffer for a lean month. Under the FTC route, she reports her full salary, offsets the US tax with Japanese income tax and residence tax, and still qualifies for the refundable credit because her earned income remains on the return. For a family like Sarah’s, the FTC can produce a refund where the FEIE produces nothing.

Her husband’s status adds another layer, because filing status choices with a nonresident alien spouse affect the result. The child tax credit side is covered in Child Tax Credit for Kids Born in Japan: Eligibility, SSN, and Refunds. In my experience this is the scenario where families most often lose money without ever realizing it.

Scenario Two: The Tokyo Engineer Earning About $100,000

David is a single engineer at a Japanese manufacturer in Shinagawa. Converted to dollars, his salary and bonuses come to about $100,000. That is below the $132,900 FEIE limit for 2026, so all of it is excludable. Nothing exceeds the cap.

Under the FEIE, his US tax on wages is zero. Under the FTC, his US tax on wages is also very likely zero, because Japanese income tax plus residence tax at his income level typically meets or exceeds the US tax on the same wages. So which should he pick?

Three things decide it. First, he has a US brokerage account with dividend-paying ETFs. Those dividends are US-source, so the US tax on them stays with either method. The FEIE adds a disadvantage, though: under the stacking rule, his dividends are taxed as though they sat on top of his excluded salary, so they land in higher brackets. Under the FTC, his salary is reported, his wage tax is offset by credits, and his dividends are taxed at their normal rates on a full return. Depending on the type of dividends, that difference can be small or meaningful.

Second, David wants to keep funding a Roth IRA. Income excluded under the FEIE does not count as compensation for IRA contributions, so if he excludes all of his salary he may have no eligible compensation left. With the FTC, his salary remains compensation and the contribution stays available.

Third, he expects raises. If his pay rises above the exclusion limit, he will want the FTC anyway, and switching away from the FEIE has consequences, discussed below. For David the FTC is usually the better long-term setup even though both methods give the same result on his wages this year.

Scenario Three: The Executive Above the Exclusion Limit

Keiko is an American executive at a foreign firm’s Tokyo office with a large salary, a performance bonus, and a housing allowance. Her foreign earned income is well above $132,900.

With the FEIE, she can exclude up to $132,900 for 2026, plus whatever foreign housing exclusion she qualifies for. Everything above that is taxable in the US, and because of stacking, it is taxed starting from high brackets. She could then claim the FTC on the Japanese tax attributable to that non-excluded portion, but she cannot claim credits for the Japanese tax on the excluded income. The calculation is complicated and often leaves money on the table.

With the FTC alone, she reports her full income and offsets it with Japan’s substantial income and residence taxes, which at her level are significant. She will very likely owe no US tax on her wages, and she will build up excess credits that carry over to other years. If she later transfers to a lower-tax posting or returns to the US with foreign-source income, those carryovers can be valuable.

For nearly everyone above the exclusion limit in Japan, the FTC is the better choice. I have yet to meet a senior executive in Tokyo who came out ahead by combining the FEIE and FTC once all the knock-on effects were counted, although a qualified preparer should confirm that for any specific case.

The Hidden Factors That Tip the Balance

Exclusion versus credit is never only about this year’s tax on your salary. The decision affects family benefits, retirement savings, self-employment obligations, and your flexibility in future years.

Child Tax Credit, IRA Contributions, and Other Knock-On Effects

As Sarah’s case showed, claiming the FEIE blocks the refundable portion of the child tax credit. For families this is often the deciding factor. A nonrefundable credit only reduces tax you would otherwise owe. If the FTC has already brought that tax to zero, a nonrefundable credit does nothing more. The refundable portion is what actually puts money in your account, and only the FTC route keeps it available.

The IRA issue appears in David’s case. If all your earned income is excluded, your IRA contribution eligibility can disappear. For Americans planning to retire in the US, or who simply want to keep a tax-advantaged account growing at home, losing that contribution room each year adds up over a decade in Japan.

There are also smaller effects. Some credits and deductions phase in or out based on income measures that excluded income still affects. Some state tax departments ignore the FEIE entirely if you have not cleanly broken state residency. Your adjusted gross income figure, which lenders and some US programs look at, can look very different depending on which method you used. None of this is visible when you are only comparing the bottom line on wages.

Self-Employment Tax and the Totalization Agreement

This is the section I wish someone had explained to me in my first freelance year in Japan. Thousands of Americans here are self-employed: freelance translators, designers, private English tutors, consultants with their own sole-proprietor registration (kojin jigyo). They often assume one of the two methods will remove their self-employment tax. Neither will.

US self-employment tax, which covers Social Security and Medicare for the self-employed, is calculated separately on Schedule SE. The FEIE does not reduce it, because self-employment tax is figured on net earnings regardless of the exclusion. The FTC does not reduce it either, because the credit applies only to US income tax and not to self-employment tax, including its Medicare portion.

The real solution is the US-Japan social security agreement, also called the totalization agreement. A self-employed American who is covered by Japan’s system, paying into Japan’s National Pension and enrolled in Japanese National Health Insurance, can get a certificate of coverage confirming that coverage. With that certificate, the American is exempt from US self-employment tax on those earnings. The relief comes from the agreement and the certificate, not from the FTC or the FEIE.

Picture Emily, a freelance illustrator in Kyoto. She uses the FTC to wipe out her US income tax, then is shocked to find a self-employment tax bill still on her return. The fix is not a different credit calculation. She needs to obtain the certificate of coverage and attach the appropriate statement to her return. For how the agreement works, see The US-Japan Totalization Agreement: Social Security and Nenkin for Americans, and for the paperwork, see Certificate of Coverage: Avoiding Double Social Insurance Contributions.

Switching Methods and the Revocation Trap

The FEIE is an election. Once you have claimed it, you can revoke it, but after revoking you generally cannot claim it again for several years without IRS consent. That restriction is the reason the decision deserves care in your first year.

Here is how it catches people. An American arrives in Japan on a teaching contract, takes the FEIE because it is simple, and keeps it for a few years. Then comes a corporate job with a large raise, or children, or a desire to fund an IRA. Switching to the FTC now means revoking the FEIE, which closes the door on coming back if circumstances change again, such as a move to a lower-tax country later.

The FTC does not have this lock-in. You can generally choose it year by year, and excess credits carry over. That flexibility is one reason most long-term residents in Japan settle on the FTC, even in years when the FEIE would have produced the same result.

Your first and last years in Japan also need attention. In the year you arrive or leave, you may have US-source wages from before the move, partial-year Japanese wages, and residence tax that arrives after you have left. The method you choose affects how cleanly that year works out. The deadlines that apply to Americans abroad are explained in US Tax Deadlines for Expats in Japan: Extensions, Estimated Payments, and Penalties.

How to Decide and File Correctly With Taxes for Expats

The theory is useful, but at some point you have to file. This is the process I recommend to friends, and it is also why I steer most Americans in Japan to a specialist instead of a generic software package.

A Step-by-Step Decision Process

1. Confirm whether you qualify for the FEIE at all, using either the bona fide residence test or the physical presence test. If you do not qualify, the FTC is your main option.
2. Add up your foreign earned income for the year in dollars, including salary, bonuses, and taxable allowances, using a consistent and defensible exchange rate method.
3. Compare that total with the annual limit: $132,900 for 2026 or $130,000 for 2025. If you are above it, the FTC is almost always the better choice.
4. List every source of income that is not earned income, such as dividends, interest, capital gains, and rent, and note whether each is US-source or foreign-source. Remember that US-source income cannot be offset by the FTC.
5. Check whether you have qualifying children. If so, estimate the refundable child tax credit you would lose under the FEIE.
6. Decide whether you want to contribute to an IRA. If so, confirm you will have eligible compensation left after any exclusion.
7. If you are self-employed, set the income tax question aside and deal with self-employment tax through a certificate of coverage under the totalization agreement.
8. Consider your plans for the next few years, including raises, a move to another country, or a return home, and weigh the FEIE revocation restriction against the FTC’s carryover flexibility.
9. Gather your Japanese tax documents, run both calculations, and pick the method that gives the better result across this year and the years you expect to follow.
10. File on time or extend properly, and keep copies of every Japanese document you used, in case the IRS asks for proof of foreign taxes paid.

Documents to Gather From Your Japanese Employer and City Hall

The FTC depends on proving how much Japanese tax you paid, so documentation matters more than it does for the FEIE. Here is what to collect.

Your gensen choshuhyo reflects the year-end adjustment your employer runs on your behalf. If any line on it is unclear, Year-End Tax Adjustment (Nenmatsu Chōsei): A Guide for Expats explains what each part means. If you have not filed in a few years and are now realizing the FTC would have helped, Streamlined Filing Procedures: Catching Up on Missed US Returns From Japan describes the catch-up route.

Why Taxes for Expats Is the Practical Answer

I have filed US returns from Japan for many years, and the most valuable lesson I learned is that the FEIE versus FTC decision is a multi-year plan, not a single checkbox. Generic tax software asks whether you lived abroad, suggests the exclusion, and moves on. It rarely flags that you just gave up a refundable child tax credit, that stacking pushed your dividends into a higher bracket, that your residence tax timing does not match, or that you are locking yourself out of a future change.

This is where Taxes for Expats is most useful. The firm focuses on Americans living abroad, so questions like “should I take the FTC with Japanese residence tax on an accrual basis” or “do I need a certificate of coverage for my freelance income” are routine work for them rather than unusual edge cases. A preparer at Taxes for Expats can run both methods side by side using your actual gensen choshuhyo, residence tax notice, and brokerage statements, and show you the difference over this year and the years ahead, not just on one return.

The pricing generally follows the complexity of your return. A single salaried employee with one employer is at the simpler end, while extra forms such as Form 1116, Form 2555, FBAR reporting, rental properties, self-employment schedules, or PFIC filings move the cost up. Exact fees change, so check the Taxes for Expats website for current figures before you commit. For a broader view of whether a specialist is worth it compared with doing it yourself, see Hiring a US Expat Tax Preparer vs DIY Software: Cost Comparison for Japan Residents.

Here is my practical advice. If you are a single teacher with no investments, no children, and no plans to save in an IRA, you may be fine handling a simple FEIE return on your own. If you have children, investments, a salary near or above the exclusion limit, freelance income, or plans to stay in Japan long term, have Taxes for Expats review your situation before you make or change an election. A one-time review can prevent several years of a poor choice. Collect your Japanese documents, list your questions, and contact Taxes for Expats early in the filing season, before the busy period.
