FEIE, explained simply

The Foreign Earned Income Exclusion (FEIE) is one of the most misunderstood tools in the US expat toolkit. It sounds like a silver bullet — earn abroad, exclude a chunk of income from US tax, done. In practice it's narrower than most nomads realize, and it quietly stops working in a handful of very common scenarios.

This is a plain-English walkthrough of what FEIE actually is, who benefits from it, and where we see people trip over it.

What FEIE actually does

FEIE lets qualifying US citizens and green card holders exclude a set amount of foreign-earned income from US federal income tax each year. The exclusion figure moves with inflation; for recent years it has sat somewhere around the low six figures per person. If you and a partner both qualify independently, you can each claim it.

Two things it does not do:

• It does not exclude self-employment tax. If you're a freelancer or a solo LLC owner, Social Security and Medicare (or their self-employed equivalents) usually keep running underneath.
• It does not exclude passive income. Dividends, interest, capital gains, rental income — none of that qualifies as "earned."

That second point is the one that catches founders. Money paid to you as a salary from your own foreign company can qualify. Money paid to you as a distribution or a dividend typically does not.

Who qualifies

To claim FEIE you need to pass one of two tests:

The Physical Presence Test

You're physically outside the United States for at least 330 full days in any rolling 12-month period. Travel days count against you — a partial day in the US is not a day abroad. Airspace over international waters is neutral; airspace over US territory is not.

The Bona Fide Residence Test

You are a genuine tax resident of another country for an uninterrupted tax year. This is the test true expats use — the ones who actually live somewhere. It requires more than a lease; it requires the country to treat you as one of its own residents for tax purposes.

Most nomads default to the Physical Presence Test, because they don't want to be a resident anywhere. That works, but it's brittle.

Where FEIE quietly breaks

The 330-day cliff

FEIE isn't graduated. If you fall short of 330 full days abroad — even by one day — the entire exclusion vanishes for that qualifying period. We've seen people lose it over a wedding, a family emergency, or a badly-timed layover in Miami. Track your days as if they matter, because they do.

The self-employment surprise

A US freelancer earning $80k abroad may exclude every dollar from income tax under FEIE and still owe five figures in self-employment tax. FEIE does nothing there. A foreign company structure or a totalization agreement can help — but that's a separate conversation.

Housing exclusion confusion

There's an additional housing exclusion layered on top of FEIE with its own math, its own limits, and its own city-by-city caps. It's real money for people in expensive cities, and it's the piece most tax software handles worst.

The "tax home" trap

To claim FEIE, your tax home has to be outside the US. If you're bouncing weekly and the IRS decides your true center of gravity is still a US zip code, they can deny the exclusion even if your day count is fine. Keep evidence that your working life is genuinely somewhere else — apartments, coworking memberships, bank accounts, invoices.

State tax doesn't care

FEIE is a federal concept. States do their own thing. California and a few other states will happily continue to consider you a resident for years after you leave if you don't actively exit. FEIE does not save you from a state tax bill.

When FEIE is the right tool

FEIE tends to shine when:

• You're a straightforward W-2 remote worker or a freelancer earning under the exclusion cap.
• You're comfortable being outside the US 330+ days a year and can prove it.
• Your income is truly earned — salary, contract fees, consulting revenue.
• You've cleanly exited any sticky state residency.

It's usually the wrong tool when your income is investment-heavy, when self-employment tax is the real cost, or when a Foreign Tax Credit (FTC) would give you more flexibility. FTC and FEIE interact — you can use them together in the same year, but not on the same dollar — and picking wrong locks you into a suboptimal setup for years.

The takeaway

FEIE is a good tool. It is not the whole toolbox. Before defaulting to it, count your days honestly, look at where your income actually comes from, and make sure the state you left is not still counting you as its own.
