A few travel days can decide whether your foreign earned income exclusion holds up. Your worldwide income generally remains subject to US income tax as a citizen abroad, so establish eligibility before relying on the exclusion. 1
This is general information. Your CPA and counsel confirm the details for your case.
The IRS requires foreign earned income, a tax home in a foreign country and either the bona fide residence test or the physical presence test. Those are connected requirements. A residence document or a calendar full of overseas trips isn't a substitute for reviewing the whole test with your CPA. 2
Start with your tax home
The IRS describes your tax home as the general area of your main place of business or employment. It also says you don't have a foreign tax home during a period when your abode is in the United States. Abode concerns your family, economic and personal ties. That makes the question more specific than where your employer sends your salary or where you booked accommodation. 3
Under the tax-home rules, an assignment expected to last, and actually lasting, one year or less is temporary; one expected to exceed a year is indefinite. Compare the expected arrangement with what actually happened. Preserve the records that explain both, rather than supplying a departure date without context. 3
Bona fide residence asks about your life abroad
The bona fide residence test requires an uninterrupted period of foreign residence that includes an entire tax year. For a calendar-year filer, that means January 1 through December 31. The test is available to US citizens and to US resident aliens who are citizens or nationals of a treaty country. 4
Living abroad for a year doesn't automatically establish the status. Going abroad to work for a specified period ordinarily doesn't make you a bona fide resident, and the IRS considers the facts reported on Form 2555. The IRS says it can't decide your status until that form is filed. Treat the explanation of your circumstances as part of the work, not an administrative afterthought. 4
Your statements to foreign authorities also matter. The IRS says you aren't a bona fide resident if you tell those authorities you aren't resident and they hold that you aren't subject to their income tax as a resident. Give your CPA the documents you've signed abroad so that the review starts with the actual record. 4
Brief or temporary trips needn't break bona fide residence when you clearly intend to return without unreasonable delay. Once established, the status can cover parts of one or two other tax years around the full year. Apply that rule to your actual dates rather than assuming every trip home destroys the claim. 4
Physical presence asks you to count full days
The alternative test requires at least 330 full days in a foreign country or countries during any twelve consecutive months. The days don't have to be consecutive. Under the IRS guidance for 2026, the test doesn't depend on your intentions or the type of residence you've established. 5
A full day is a continuous 24-hour period beginning and ending at midnight. Time on or over international waters when traveling to or from the US doesn't count. Travel outside any foreign country lasting 24 hours or more loses full days. Keep arrival and departure details, not just a rough total of nights away. 5
The twelve-month period may start on any day and may overlap another qualifying period. You can choose the period giving the greatest exclusion. Publication 54 also states that your foreign tax home must exist throughout the qualifying presence period, meaning the 330 full days rather than necessarily the entire twelve months. Check the tax-home condition alongside the day count. 5, 1
What this means for you
Your intended travel pattern must support the eligibility test you plan to use. Reconcile your full-day count with your tax home and residence evidence now. Discovering a shortfall after the qualifying period closes leaves you planning from a different position.
What to do this month
- Reconstruct your travel calendar from bookings and arrival records. Record actual dates and distinguish time in a foreign country from time in transit.
- Identify the twelve-month periods that need testing. Keep the evidence for your work base beside the day count so the tax-home requirement isn't overlooked.
- Document your home, work and family arrangements in plain language. Preserve the information you have already provided to foreign authorities about your residency.
- Check planned trips against the intended qualifying period before you book them. Treat a potential shortfall as a problem to resolve now, not an explanation to write later.
Common mistakes to avoid
- Treating a foreign visa as automatic FEIE eligibility.
- Counting travel over international waters as qualifying presence.
- Using approximate dates instead of full-day records.
- Reviewing travel while leaving your US abode unexplained.
The FNC angle
When you discuss residency and business structure with FNC, bring the travel and work arrangements you actually intend to maintain. The practical plan should give your CPA clear facts to assess. A residency route can be part of that discussion, but it should never be sold to you as an automatic answer to a US tax test.
