FEIE Explained: How to Save Thousands on Taxes Living Abroad

The United States is one of only two countries in the world that taxes its citizens on worldwide income, regardless of where they live. If you're an American living in Lisbon and earning money from a US-based remote job, the IRS still wants to hear from you.

But here's the good news: the Foreign Earned Income Exclusion (FEIE) allows qualifying Americans abroad to exclude a significant chunk of their income from US federal taxes. For 2026, that amount is $130,000. If you earn below that threshold — as most expats do — your federal tax bill on earned income drops to zero.

Let's break down exactly how this works.

What Is the FEIE?

The Foreign Earned Income Exclusion is a provision in the US tax code (Internal Revenue Code Section 911) that allows US citizens and resident aliens living abroad to exclude foreign earned income from their US taxable income. It has existed in various forms since 1926 and is adjusted annually for inflation.

Key details for 2026:

• Maximum exclusion: $130,000 per person
• Filing form: Form 2555 (attached to your regular 1040)
• Applies to: Earned income only (salary, wages, self-employment income)
• Does not apply to: Investment income, rental income, pensions, Social Security, capital gains

If you're married and both spouses work abroad, each person can claim their own exclusion — potentially excluding up to $260,000 combined.

The Two Qualification Tests

To claim the FEIE, you must meet one of two tests. You only need to pass one, not both.

1. The Physical Presence Test

This is the more straightforward test and the one most expats use. You must be physically present in a foreign country (or countries) for at least 330 full days during any 12-month period.

Important details:

• The 12-month period does not have to be a calendar year. You can choose any 12-month period that works in your favor.
• "Full days" means entire 24-hour periods. The day you leave the US and the day you return don't count.
• Days spent in international waters or airspace don't count as days in a foreign country.
• You can be in multiple foreign countries — you don't have to stay in one place.
• You have a maximum of 35 days in the US per year (365 minus 330). Plan your trips home carefully.

Example: Sarah leaves the US on January 15, 2026, and moves to Mexico City. She does not return to the US until December 20, 2026, for a two-week holiday visit. She was outside the US for approximately 339 days. She passes the Physical Presence Test.

2. The Bona Fide Residence Test

This test is more subjective. You must establish that you are a bona fide resident of a foreign country for an uninterrupted period that includes a full calendar year.

Factors the IRS considers:

• Do you have a permanent home in the foreign country?
• Have you registered as a resident or obtained a residence visa?
• Do you pay local taxes?
• Are you involved in the local community (bank accounts, memberships, etc.)?
• Do you intend to stay indefinitely, or is there a clear end date?

The Bona Fide Residence Test is more flexible about trips back to the US — there's no strict 35-day limit. However, it requires more documentation and can be harder to defend in an audit. It also requires an entire calendar year, so you can't claim it in your first year if you moved abroad mid-year.

Our recommendation: Use the Physical Presence Test if you can. It's objective, easy to prove, and available from day one. Track your travel days meticulously — a simple spreadsheet works.

How to Claim the FEIE: Form 2555

To claim the exclusion, you file Form 2555 with your annual tax return. Here's what you'll need:

• Your foreign address and the country where you earned income
• Dates you were present in foreign countries (for the Physical Presence Test)
• Your employer's name and address (or your own if self-employed)
• The amount of foreign earned income you want to exclude

You still file a regular Form 1040. The FEIE doesn't exempt you from filing — it just reduces your taxable income. Even if your exclusion zeroes out your tax liability, you must file.

Filing deadline for expats: US citizens abroad get an automatic 2-month extension, making the deadline June 15 instead of April 15. You can request a further extension to October 15 if needed.

The Foreign Housing Exclusion

In addition to the FEIE, you may be able to exclude or deduct certain housing expenses through the Foreign Housing Exclusion (for employees) or Foreign Housing Deduction (for the self-employed).

This covers reasonable housing expenses above a base amount (16% of the FEIE limit, so about $20,800 in 2026). Qualifying expenses include rent, utilities, insurance, and parking, but not extravagant costs. The maximum varies by city — high-cost cities like London, Hong Kong, and Tokyo have higher limits.

This is particularly useful if you live in an expensive city and your rent exceeds the base threshold.

Common FEIE Mistakes

1. Spending Too Many Days in the US

The 330-day requirement for the Physical Presence Test leaves you only 35 days per year in the US. A Thanksgiving trip plus a summer wedding can eat that up fast. Track every day. If you're close to the limit, consider scheduling trips to straddle calendar years strategically.

2. Forgetting to File Form 2555

The FEIE is not automatic. If you forget to file Form 2555, you don't get the exclusion. You can file a late claim, but it requires IRS approval and can be a headache. File on time.

3. Thinking FEIE Covers All Income

FEIE only covers earned income. If you have investment income, rental income, or capital gains, those are still taxable. You may need to use the Foreign Tax Credit (Form 1116) for those types of income instead.

4. Ignoring State Taxes

The FEIE is a federal exclusion. Many US states have their own tax rules for former residents:

• California: Notoriously aggressive. May consider you a resident if you maintain any ties (bank accounts, driver's license, property).
• Virginia, New Mexico, South Carolina: Have been known to tax former residents who haven't clearly established domicile elsewhere.
• Texas, Florida, Nevada, Wyoming, Washington, Alaska, South Dakota, New Hampshire, Tennessee: No state income tax. If you lived in one of these states before moving, you're in the clear.

If you lived in a state with income tax, consult a tax professional about how to formally change your domicile before you leave.

5. Not Understanding Self-Employment Tax

The FEIE excludes your income from federal income tax, but it does not exclude it from self-employment tax (Social Security and Medicare). If you're a freelancer or run your own business, you'll still owe the 15.3% SE tax on your earnings, even if you owe zero income tax. This surprises a lot of people.

There are some workarounds — for example, if you're a tax resident of a country with a Totalization Agreement with the US (about 30 countries), you may be able to pay into their social security system instead of the US system.

When the FEIE Doesn't Make Sense

The FEIE isn't always the best choice. Here are situations where the Foreign Tax Credit (FTC) might serve you better:

• High earners: If you earn well above $130,000, the FEIE only covers part of your income. The FTC can offset US taxes dollar-for-dollar based on what you paid in foreign taxes.
• High-tax countries: If you live in a country with taxes higher than US rates (much of Western Europe), the FTC can eliminate your US tax bill entirely and give you excess credits to carry forward.
• Investment income: The FTC covers all types of income, not just earned income.
• Planning to return soon: If you revoke the FEIE, you cannot re-elect it for 5 years without IRS approval. Consider this carefully.

You can use the FEIE and FTC together, but not on the same income. A good expat tax preparer can model both scenarios and tell you which saves more.

FBAR and FATCA: The Reporting Requirements

Separate from taxes, you have two reporting requirements if you have foreign financial accounts:

FBAR (FinCEN Report 114)

• Required if: The combined value of all your foreign bank accounts exceeds $10,000 at any point during the year
• Filed with: FinCEN (not the IRS) through the BSA E-Filing System
• Deadline: April 15, with automatic extension to October 15
• Penalties for non-filing: Up to $10,000 per account per year for non-willful violations; much higher for willful violations

FATCA (Form 8938)

• Required if: Your foreign financial assets exceed $200,000 at year-end or $300,000 at any point during the year (thresholds for single filers living abroad)
• Filed with: The IRS, attached to your tax return
• Covers: Bank accounts, investment accounts, foreign pensions, and other financial assets

These are reporting requirements, not additional taxes. But the penalties for ignoring them are severe. If you have any foreign accounts, file both reports.

The Bottom Line

For most Americans earning under $130,000 abroad, the FEIE is a powerful tool that can reduce your federal income tax to zero. The key steps:

1. Spend at least 330 days outside the US in a 12-month period
2. Track your travel days carefully
3. File Form 2555 with your tax return
4. File your FBAR and FATCA reports if applicable
5. Don't forget about state taxes and self-employment tax
6. Hire an expat tax specialist — it's worth the $300-$800 they charge

The FEIE is one of the biggest financial advantages of living abroad as an American. Use it correctly, and you'll keep thousands of dollars that would otherwise go to the IRS.
