Residency tests for expat tax benefits

What is the bona fide residence test?

The bona fide residence test is one of two ways to qualify for the Foreign Earned Income Exclusion, and it works by proving — through your actual living situation, not just a day count — that you've genuinely established residency in a foreign country for an entire uninterrupted calendar year. Unlike a simple day-counting rule, this is a facts-and-circumstances test: the IRS looks at your housing, employment, family situation, and community ties abroad to judge whether your residence is real and intended to be lasting, not just an extended visit. TFX's bona fide residence test guide covers the full qualification standard.

How is the bona fide residence test different from the physical presence test?

The bona fide residence test is subjective — it asks whether your foreign home and ties are genuine and lasting over a full calendar year — while the physical presence test is purely objective, requiring 330 full days abroad in any 12-month period with no consideration of your personal circumstances at all. That makes bona fide residence a better fit for people with stable, long-term foreign housing and employment, while the physical presence test suits frequent travelers, mid-year movers, and digital nomads who can't show a settled full-year residence but can document their days. Both unlock the same Foreign Earned Income Exclusion amount — TFX compares them directly in its bona fide residence vs. physical presence test guide.

How do I establish bona fide residence in a foreign country?

You establish bona fide residence by building a genuine life abroad — a lease or owned home rather than a temporary rental, steady local employment or business activity, family relocating with you, and integration into the community through things like local bank accounts and school enrollment. The IRS weighs these factors together rather than requiring any single one, but keeping strong ties back home — like a permanent US residence or ongoing US employment — can actively work against your claim even if you technically spend the year abroad. TFX's bona fide residence test guide lists the specific factors the IRS considers.

Does a short trip back to the US break my bona fide residency?

No — brief visits back to the US are allowed and don't automatically break your bona fide residency, as long as your overall pattern still shows a genuine, uninterrupted foreign residence. The risk isn't the trip itself but the pattern it creates: extended stays or frequent returns to the US can undermine your claim by suggesting your real home never left, so occasional short visits are treated very differently from a pattern that starts to look like you're actually still based in the US. TFX's bona fide residence test guide covers how travel patterns factor into this determination.

Can I pass the bona fide residence test in my first year abroad?

Not entirely on its own — bona fide residence requires an uninterrupted period that includes one full calendar year (January 1 to December 31), so a partial first year abroad can't independently satisfy the test until you've completed that full year. Once you do complete the full calendar year, though, the qualifying period can extend backward to cover the partial months of your arrival year as well — many expats handle this by filing Form 2350 to extend their filing deadline until they've established eligibility, rather than filing early and missing the exclusion. TFX's bona fide residence test guide covers the full calendar year requirement.

What documents help prove bona fide residence?

Strong documentation includes a foreign lease or property deed, your residency permit or visa, a foreign employment contract, local bank account statements, and school enrollment records for any children who relocated with you. The common thread across all of these is that they show ongoing, real-world commitments abroad rather than a temporary arrangement — the more of these you can produce covering the full period you're claiming, the stronger your case if the IRS ever questions your bona fide residence claim. TFX's bona fide residence test guide lists the documentation the IRS looks for.

Does having a visa time limit prevent me from claiming bona fide residency?

Not automatically — there's no bright-line rule that a fixed-term visa disqualifies you, since visa type is just one factor the IRS weighs alongside your housing, employment, and community ties, not a standalone deciding one. That said, a long-term visa or permanent residency status generally strengthens your claim, while a purely temporary visa (like a tourist visa, which wouldn't legally support genuine residence in the first place) can hurt it — the practical question is always whether your overall situation shows a genuine, intended-to-be-lasting residence, regardless of what your visa's expiration date says. TFX's bona fide residence test guide notes how visa status factors into the broader determination.

What is the physical presence test for US expats?

The physical presence test is the objective, day-count alternative to the bona fide residence test for qualifying for the Foreign Earned Income Exclusion — instead of proving your ties abroad are genuine, you simply need to document enough qualifying days physically present in one or more foreign countries. This makes it a much more mechanical test: there's no facts-and-circumstances judgment call, just a day count that either clears the bar or doesn't, which is why it's often the more reliable option for people who move frequently or can't easily document a settled foreign residence. TFX's physical presence test guide covers how the test is structured.

How many days must I spend outside the US to pass the physical presence test?

You need at least 330 full days in one or more foreign countries within any 12-month period — roughly 11 months out of the year, leaving about 35 days of flexibility for US travel or time that doesn't count as foreign presence. Those 330 days don't need to be consecutive and can be spread across multiple countries, but they all have to fall within whichever 12-month window you choose to test against. TFX's physical presence test guide explains how to select the most favorable 12-month period.

How do I count days for the 330-day rule?

A qualifying day is a full 24-hour, midnight-to-midnight period spent physically in a foreign country — your travel day when you leave the US typically doesn't count (it's a partial foreign day), and neither does your travel day when you return, since time spent over international waters or airspace doesn't count as foreign-country presence either. Because the standard is this precise, a single miscounted day can turn a passing 330 into a failing 329, so it's worth tracking your travel dates carefully rather than estimating. TFX's physical presence test guide walks through this day-counting methodology with examples.

Do transit days in the US count against the physical presence test?

Generally yes — any time physically present in the US can count against your qualifying days, but there's a narrow exception for transit: passing through the US for less than 24 hours while traveling between two points outside the country is not treated as US presence. This exception is easy to lose by accident — a longer layover, an overnight stay, or any delay that pushes you past 24 hours in the US turns that transit into disqualifying US presence for that day. TFX's physical presence test guide covers this transit rule in more detail.

What if my 12-month period straddles two tax years?

That's completely normal and allowed — your qualifying 12-month period doesn't need to align with the calendar year, so a period like September through the following September works fine, and it can straddle two different tax years. When it does straddle two years, your maximum Foreign Earned Income Exclusion for each tax year gets prorated based on how many of your qualifying days actually fall within that specific year, rather than giving you the full annual exclusion amount in both years. TFX's physical presence test guide explains how this proration works.

Can I use the physical presence test and still spend some time in the US?

Yes — the test doesn't prohibit US travel at all; you just need your chosen 12-month period to still contain at least 330 full foreign days, which leaves roughly 35 days you can spend in the US or anywhere else without jeopardizing your eligibility. The one thing that can still trip you up regardless of your day count is maintaining a permanent home (an "abode") in the US — that creates a separate tax-home problem that can block your Foreign Earned Income Exclusion eligibility even if your day count technically passes. TFX's physical presence test guide covers this abode caveat in more detail.
