How Do I Establish a Tax Home in a Foreign Country?

Your tax home is wherever you permanently or indefinitely work, not where your family lives. According to the IRS, your tax home is “the general area of your main place of business, employment, or post of duty, regardless of where you maintain your family home.” To claim the Foreign Earned Income Exclusion (up to $130,000 for the 2025 tax year) or the Foreign Housing Exclusion, you must have a tax home in a foreign country for your entire qualifying period.

Three factors determine whether you pass the tax home test:

Where you work: Your main place of business or employment must be abroad
Where your abode is: Your personal, family, and economic ties cannot be primarily in the U.S.
How long you plan to stay: Your foreign assignment must be indefinite, not temporary (one year or less)

Here is how each factor works, what can disqualify you, and how to document your tax home to protect your FEIE claim.

Not Sure If You Have a Foreign Tax Home Yet?

You’ll get clarity on whether you qualify for the Foreign Earned Income Exclusion and how to structure your residency properly.

What Is the Tax Home Test and Why Does It Matter?

The tax home test is a prerequisite for both the Foreign Earned Income Exclusion and the Foreign Housing Exclusion. Even if you pass the physical presence test (330 days abroad) or the bona fide residence test (full calendar year as a foreign resident), you still will not qualify for the FEIE if your tax home is in the United States.

This is where many expats get tripped up. You can spend 340 days abroad and still fail the tax home test if your main place of business remains in the U.S. or if your abode (personal and economic ties) stays rooted there.

The IRS applies three rules in order to determine your tax home:

Your regular or main place of business: If you have one primary work location abroad, that is your tax home. This is the most straightforward scenario and applies to most expats with a single employer or business location overseas.
Where you regularly live: If you do not have a regular or main place of business (for example, you work in multiple locations), the IRS looks at where you regularly live. If you maintain a consistent residence abroad, that becomes your tax home.
Wherever you work (itinerant): If you have neither a regular place of business nor a regular residence, the IRS considers you “itinerant,” and your tax home is wherever you happen to work. This classification matters for digital nomads and frequent travelers, since it means your tax home shifts with your location.

What Is the Difference Between “Tax Home” and “Abode”?

This is one of the most misunderstood parts of the tax home test, and getting it wrong can cost you the entire $130,000 FEIE exclusion.

Tax home is a vocational concept. It refers to where you work.
Abode is a domestic concept. It refers to where you maintain your personal, family, and economic connections. The IRS defines abode as “one’s home, habitation, residence, domicile, or place of dwelling” and clarifies that it “has a domestic rather than a vocational meaning.”

The critical rule: You are not considered to have a tax home in a foreign country for any period during which your abode is in the United States. In other words, even if you work abroad full-time, you fail the tax home test if your abode remains in the U.S.

The location of your abode depends on where you maintain your family, economic, and personal ties. The IRS considers the totality of your connections, not any single factor in isolation.

Factors the IRS Considers When Determining Your Abode

Factor	Points Toward U.S. Abode	Points Toward Foreign Abode
Family residence	Spouse and children remain in the U.S.	Family lives with you abroad
Primary home	You maintain a home in the U.S. that is available for your use	Your U.S. home is rented out or sold; your primary home is abroad
Bank accounts	Primary accounts are in the U.S.	You have opened and actively use foreign bank accounts
Social ties	Memberships, religious organizations, and community involvement in the U.S.	You have joined local organizations, clubs, or communities abroad
Driver’s license	Active U.S. license only	Obtained a local driver’s license abroad
Voter registration	Registered and voting locally in the U.S.	(U.S. citizens can vote absentee; this factor alone is not decisive)
Professional licenses	Active in a U.S. state	Obtained professional registration in a foreign country

Important

No single factor is decisive. The IRS looks at the overall picture. Owning a home in the U.S. does not automatically make your abode the U.S. if your spouse and children live with you abroad and you have rented out the U.S. property. Similarly, owning property abroad does not automatically make your abode foreign if all your personal and economic connections remain in the U.S.

IRS Example: Abode in the U.S. (Fails the Test)

The IRS provides this example: You work on an offshore oil rig in the territorial waters of a foreign country on a 28-day-on, 28-day-off schedule. You return to your family home in the U.S. during your off periods. Even though you spend half the year working abroad, your abode is in the United States because your family, economic, and personal ties are centered there. You cannot claim the FEIE.

IRS Example: Abode Abroad (Passes the Test)

Your employer transferred you to a foreign country for an indefinite period. You rented out your U.S. home, stored your car, and moved your spouse, children, furniture, and pets to London. You leased a car and obtained a local driver’s license. You and your spouse opened foreign bank accounts, joined a local business league, and became active in the neighborhood civic association. Your abode is in a foreign country, and you pass the tax home test.

Does a Temporary vs. Indefinite Assignment Affect My Tax Home?

Yes. This distinction is one of the most common reasons expats lose the FEIE.

Temporary assignment (one year or less): If you expect your work abroad to last one year or less, the IRS considers it temporary. Your tax home remains in the United States, and you do not qualify for the FEIE, even if you meet the physical presence test.
Indefinite assignment (more than one year): If you expect your work abroad to last more than one year, it is considered indefinite. Your tax home shifts to the foreign country, assuming your abode is not in the U.S.

The expectation rule matters: What counts is your reasonable expectation at the time. If you initially expect a one-year assignment (temporary), your tax home stays in the U.S. But if your expectation changes and you later expect to stay longer than one year, your assignment becomes indefinite from the date your expectation changes, not retroactively.

Scenario	Assignment Type	Tax Home	FEIE Eligible?
Six-month consulting project abroad	Temporary	United States	No
Two-year employment contract abroad	Indefinite	Foreign country	Yes (if abode is also abroad)
One-year contract, extended to two years after six months	Temporary for the first six months, indefinite after expectation changes	Shifts from the U.S. to a foreign country on the date the expectation changed	Eligible from the date of change in expectation
“Indefinite” assignment abroad, but you maintain your U.S. home and family stays in the U.S.	Indefinite by duration, but abode may be in the U.S.	Maybe in the U.S. despite working abroad	Possibly not, depends on abode analysis

Pro Tip

If you are on a contract with a defined end date of one year or less, the IRS will treat it as temporary regardless of your intent to stay longer. Get your contract terms documented clearly. If there is any possibility your assignment will extend beyond one year, ensure your employment agreement reflects that from the start.

How Do Digital Nomads Establish a Tax Home Abroad?

Digital nomads and location-independent workers face a unique challenge: without a single employer or fixed office abroad, it can be harder to establish a foreign tax home.

If you move between countries every few weeks or months, the IRS may classify you as “itinerant.” As an itinerant, your tax home is wherever you work. This can actually work in your favor, because your tax home shifts to each foreign country as you work there, which means it is not in the United States.

However, there is a risk. If you spend significant time working from the U.S. between trips, or if you maintain your primary economic and personal ties in the U.S., the IRS could argue that your abode (and therefore your tax home) remains in the United States.

To strengthen your foreign tax home as a digital nomad:

Establish a “home base” abroad where you return regularly and maintain a lease or rental agreement
Open and actively use a bank account in your home base country
Obtain a local phone number, driver’s license, or other government-issued identification
Minimize ties to the U.S. (close unnecessary accounts, update your mailing address, rent out or sell your U.S. home)
Track your days meticulously and document your work locations abroad

What About Military Contractors and Combat Zone Workers?

If you work in a designated combat zone in support of the U.S. Armed Forces, a special rule applies: your abode is not considered to be in the United States, regardless of where your family and personal ties are located. This exception was added by the Tax Cuts and Jobs Act for tax years beginning after December 31, 2017.

This means that a military contractor working in a combat zone who maintains a family home in the U.S. can still pass the tax home test, as long as they also meet the physical presence test or bona fide residence test.

Take Note

This exception applies to civilians working in support of the Armed Forces, not to active-duty military personnel (who are covered by a separate Combat Zone Exclusion). It also does not apply to contractor work in foreign countries that are not designated combat zones, even if the work is dangerous.

For more on how military contractor taxes work, see our guide on military contractor tax obligations abroad.

What Does “Foreign Country” Mean for the Tax Home Test?

The IRS defines a “foreign country” as any territory under the sovereignty of a government other than the United States. This includes the country’s airspace, territorial waters (within 12 nautical miles), and adjacent seabed areas where the country has exclusive rights to resources under international law.

These locations do not count as a foreign country:

U.S. territories: Puerto Rico, Guam, U.S. Virgin Islands, American Samoa, Commonwealth of the Northern Mariana Islands
International waters and airspace
The Antarctic region
Offshore installations outside the territorial waters of any foreign country

If you work on a ship or oil platform, the location matters. Working within 12 nautical miles of a foreign country’s coast counts as being in that country. Working on an offshore platform outside any country’s territorial waters does not count.

How Do I Document My Foreign Tax Home?

If the IRS challenges your FEIE claim, the burden of proof is on you to demonstrate that your tax home and abode were in a foreign country. Strong documentation can mean the difference between keeping your $130,000 exclusion and losing it entirely.

Records to maintain:

Foreign lease or mortgage agreement showing your residence abroad
Foreign utility bills in your name (electricity, water, internet)
Foreign bank account statements showing regular activity
Foreign driver’s license, national ID, or residence permit
Employment contract showing your work location and duration abroad (especially if the assignment is indefinite)
Local memberships and community involvement (gym, clubs, religious organizations, school enrollment for children)
Travel records showing your pattern of living abroad (flight itineraries, passport stamps)
Records of U.S. property being rented out or sold

Build your documentation file from the day you move abroad, not when the IRS asks for it. A comprehensive file that shows consistent foreign ties over months and years is far more persuasive than a last-minute collection of a few receipts.

What Happens If I Fail the Tax Home Test?

If the IRS determines that your tax home or abode was in the United States during your qualifying period, you lose the FEIE and the Foreign Housing Exclusion for that period. The consequences can be significant:

Tax bill: All foreign-earned income that you previously excluded becomes taxable. On $130,000 of income, this could result in $25,000 or more in federal income tax.
Accuracy-related penalty: The IRS may impose a 20% accuracy penalty on the underpayment.
Interest: Interest accrues from the original due date of the return.
State tax implications: Some states may also recalculate your state liability.

If you cannot pass the tax home test, you are not without options. The Foreign Tax Credit provides a dollar-for-dollar credit for income taxes paid to a foreign government, and it does not require the tax home test. Many expats in high-tax countries find that the FTC eliminates their U.S. tax liability without needing the FEIE at all. See our FEIE vs. FTC comparison to determine which strategy works best for your situation.

Frequently Asked Questions

My spouse and children live in the U.S. while I work abroad. Can I still pass the tax home test?

Possibly, but it is harder. The IRS will look at the totality of your connections, not just where your family lives. If your work assignment abroad is indefinite and you have established meaningful foreign ties (foreign bank account, local memberships, a residence abroad), you may still pass. However, a spouse and children living in the U.S. weigh heavily in the abode analysis. The IRS oil rig example shows how a regular pattern of returning to a U.S. family home can disqualify you.

I own a home in the U.S. but rent it out while I live abroad. Does that disqualify me?

No. The IRS specifically states that your abode is “not necessarily in the United States merely because you maintain a dwelling in the United States.” Renting out your U.S. home to another family actually strengthens your position because it shows you are not using it as your primary residence. The key is that your overall pattern of personal, economic, and family ties points abroad, not to the U.S.

I work remotely for a U.S. company from abroad. Is my tax home in the U.S. or abroad?

Your tax home is based on where you perform the work, not where your employer is located. If you are physically working from Berlin for a company headquartered in San Francisco, your tax home is in Germany. This is one of the most important distinctions for remote workers and digital nomads. The location where you sit and do the work is what matters.

How long do I need to live abroad to establish a foreign tax home?

There is no specific minimum duration. What matters is whether your assignment is indefinite (expected to last more than one year) and whether your abode is in a foreign country. An expat who moves abroad on a two-year contract with their family can establish a foreign tax home from day one. A consultant on a six-month project cannot.

Can I claim the FEIE if I am classified as “itinerant”?

Yes, if your itinerant work locations are all in foreign countries and your abode is not in the United States. Being itinerant does not disqualify you from the FEIE. It simply means your tax home moves with you. For digital nomads who travel abroad without returning to the U.S. for extended periods, itinerant status can support FEIE eligibility.

What if the IRS disagrees with my tax home determination?

If the IRS challenges your FEIE claim during an audit, they will review your documentation and the totality of your circumstances. Having comprehensive records (lease, bank statements, utility bills, and community involvement) significantly strengthens your case. If you are unsure about your tax home status, getting a professional review before filing is far less expensive than defending an audit after the fact.

Your tax home determination is the foundation of your entire FEIE claim. Getting it right protects up to $130,000 in excluded income; getting it wrong can trigger a $25,000 or more tax bill, plus penalties and interest. The good news is that most Americans who genuinely live and work abroad will pass the test without difficulty.
