FEIE Physical Presence Test 2026: 330-Day Rule Explained (Deep Dive)
The Physical Presence Test (PPT) is one of two ways to qualify for the Foreign Earned Income Exclusion (FEIE) — the other being the Bona Fide Residence Test. PPT is the more mechanical of the two: count your days outside the US correctly, and you qualify; miscount, and you owe US tax on income you thought was excluded.
This guide explains exactly how the 330-day Physical Presence Test works in 2026, what counts as a “full day” abroad, common errors that disqualify expats every year, and how to plan your moves to ensure FEIE eligibility.

TL;DR — what the Physical Presence Test requires
To qualify for FEIE under PPT in 2026, you must:
- Be physically present in a foreign country (or countries) for at least 330 full days during any consecutive 12-month period
- Count “full days” — full 24-hour periods entirely outside the United States and US territories
- Exclude transit days that include any US presence
- Have your “tax home” in a foreign country during this period
The 12-month window doesn’t have to align with the calendar year — it can be any 12 consecutive months. This flexibility is critical for moves mid-year.
How “330 full days” actually works
Count carefully — this is where most expats slip up.
What counts as a “full day”
A “full day” is a complete period of 24 consecutive hours during which you are physically present in a foreign country.
Example: You arrive in Madrid at 11:00 PM on June 1. June 1 is NOT a full day in Spain (only 1 hour qualifies). June 2 is your first full day in Spain (24 hours).
Example: You depart Madrid for New York at 8:00 AM on December 31. December 31 is NOT a full day in Spain (only 8 hours qualify before US-bound flight).
What disqualifies a day
Any presence in the US during the 24-hour period disqualifies that day from the count.
Example: You’re in Madrid June 1-29. On June 30 you fly to NYC for a weekend (back to Madrid July 2). June 30 is disqualified (you were in the US that day). July 1 is disqualified (US that day). July 2 may or may not be disqualified depending on arrival time in Madrid.
Example: You’re in Mexico City January 1 to December 31, 2025, with a single 1-hour layover in Houston on July 15 to change flights. July 15 is NOT a full day in Mexico (you were in the US during that 24-hour period — even briefly). 364 days qualified, 1 day disqualified, total 364 — exceeds 330 ✅.
Transit days — partial-day rule
Days that include any US presence (boarding a flight in the US, layover in a US airport, brief shore visits during cruises, brief border crossings) are not “full days abroad.”
Practical implication: If you fly Madrid → NYC → Mexico City → onward, both the day you arrive in NYC AND the day you depart NYC for Mexico City are likely disqualified.
What ABOUT international waters / international airspace?
Days spent entirely in international waters (cruise ships in international waters, ocean voyages) or international airspace count as “outside the US” — but they are not “in a foreign country” either, so they don’t count toward your 330 days.
If you cruise from New York to Lisbon over 7 days, none of those 7 days count toward your 330. (You’d need 330 full days in foreign countries, separate from transit.)
The 12-month window — pick wisely
You don’t have to use January 1 to December 31. You can pick any consecutive 12-month period, and the IRS allows you to optimize.
Standard pattern (most expats)
Use calendar year January 1 – December 31. Simpler bookkeeping; aligns with US tax year.
Mid-year move pattern
If you moved abroad on, say, March 15, 2025:
- A January-December 2025 window has only ~290 days abroad — fails
- A March 15, 2025 – March 14, 2026 window may have 350+ days abroad — passes!
You claim FEIE for tax year 2025 using the 12-month period March 15, 2025 – March 14, 2026 (proration applies — see below)
Proration when 12-month window doesn’t align with tax year
If your qualifying 12-month window crosses tax years (March 2025 – March 2026 example), you can only claim FEIE for the portion of that window falling within the tax year you’re filing.
For tax year 2025: you can claim FEIE for the period March 15, 2025 – December 31, 2025 (~292 days). The FEIE exclusion amount is prorated to ~292/365 = ~80% of the full FEIE limit.
If full FEIE limit for 2025 is $130,000 (or $132,900 in 2026), your prorated maximum scales accordingly — e.g., for a 292-day-in-2025 window, max FEIE ≈ $130,000 × 292/365 ≈ $104,000.
The remaining 73 days of your 12-month window (January 1 – March 14, 2026) apply to your 2026 tax return separately.
This proration trips up many expats. For mid-year moves, FEIE doesn’t give you the full $132,900 exclusion in the first year — only a portion.
Common Physical Presence Test mistakes
1. Forgetting layover days
You traveled Madrid → Lisbon, but had a 4-hour Heathrow connection. Heathrow is in the UK (foreign country), so doesn’t disqualify.
You traveled Madrid → Mexico City via JFK with a 2-hour layover. JFK is in the US. That day is disqualified from your “foreign country” count.
2. Underestimating US visits home
You spent 35 days in the US over the year (vacations, family events, doctor appointments, business trip). 35 days × 24 hours = 35 disqualified days. 365 – 35 = 330. You barely make it.
If 36 days, you fail PPT for that 12-month window.
3. Using calendar-year window when mid-year move would help
You moved abroad April 15. A calendar-year window has ~260 days abroad — fails. A April 15 – April 14 window has ~330 days — passes! Many expats default to calendar year and unnecessarily fail.
4. Cruise / ocean voyage time
A 14-day Atlantic crossing counts as 0 days toward your 330 (international waters, not foreign countries). If you spent 30 days on cruises during the year, those 30 days don’t help your count.
5. Time in US territories
US territories (Puerto Rico, US Virgin Islands, Guam, American Samoa, Northern Mariana Islands) count as US presence, NOT foreign country presence. Days in Puerto Rico count against your count, not toward your 330.
6. Brief border crossings
You’re living in Mérida and you drive across the border to McAllen, Texas, for an afternoon shopping trip (8 hours). That day is disqualified. Repeat 30 times during the year and you’ve eliminated 30 qualifying days.
Documenting your PPT compliance
The IRS may request documentation of your PPT qualification. Maintain:
Day-by-day calendar
A simple spreadsheet showing each day of the 12-month window:
- Date
- Country (foreign or US)
- Notes (travel, etc.)
Some expats use travel-tracking apps (TripIt, App in the Air) that auto-import flight data. These produce an audit-ready record.
Supporting documents
- Passport stamps (entry/exit stamps from foreign countries; US re-entry stamps)
- Boarding passes (if available — many airlines provide PDF copies via app)
- Hotel/Airbnb receipts (date stamps)
- Bank statements (foreign-country ATM withdrawals show physical presence)
- Cell phone records (if relevant; cell tower locations can prove presence)
- Foreign rental contracts
If you’re audited, the IRS will ask “prove you were in [foreign country] from X to Y.” Having day-by-day documentation makes this trivial.
Physical Presence Test vs. Bona Fide Residence Test
The IRS provides two paths to FEIE qualification. Both have their place.
| Factor | Physical Presence Test (PPT) | Bona Fide Residence Test (BFRT) |
|---|---|---|
| Mechanical/objective? | ✅ Yes — count days | ❌ No — facts and circumstances |
| Time required | 330 full days in any 12-month period | Full tax year as bona fide resident |
| Best for | Digital nomads, recent movers, those traveling internationally | Long-term expats settled in one foreign country |
| First-year qualification | Possible (with proration) | Difficult — requires full tax year |
| Trip-home flexibility | Limited (every day in US counts against 330) | More flexibility (can take longer trips home if not “abandoning” foreign residence) |
| IRS disputes | Less likely (objective day count) | More likely (subjective — IRS can dispute “bona fide” status) |
Most digital nomads and recent expats use PPT. Most long-term established expats (5+ years in the same country, family, home, etc.) use BFRT.
If you qualify for both, PPT is generally simpler/safer.
Edge cases and special situations
What if I’m in a “war zone” or “qualifying combat zone”?
For combat zones (military or contractor), days in qualifying combat zones may have special rules under IRC Section 911. Get specialist advice if applicable.
What if I’m a US government employee abroad?
Different rules apply. Federal employees abroad generally cannot claim FEIE on government-source income. Check Form 2555 instructions and consult a tax preparer.
What if I’m a flight attendant / international pilot?
Special rules for transportation industry workers. Most flight attendants/pilots use FTC rather than FEIE due to complex day-counting.
Can I count “non-residence” days in foreign countries?
Days when you’re physically present in a foreign country but not residing there (e.g., business trip to Tokyo while your home is in Lisbon) count toward your 330 days. Physical presence is what matters for PPT, not residency status.
What about Antarctica?
Antarctica is not a “foreign country” for FEIE purposes — it’s no country. Days in Antarctica count as 0 toward your 330. Niche edge case but worth knowing for researchers/scientists.
What about international waters (yacht owners)?
Days spent on a yacht in international waters count as 0. To qualify for PPT, you need to be physically in foreign countries for those 330 days.
Worked examples
Example 1 — Standard expat, calendar year
Sarah moved to Lisbon January 1, 2025. She spent 4 weeks back in the US in 2025 (Christmas at home + spring trip). 365 – 28 = 337 full days in Portugal/Europe.
Result: 337 ≥ 330 → PPT passed for 2025. Full FEIE available ($132,900 limit) for 2025 tax year.
Example 2 — Mid-year mover
David moved to Mexico City April 15, 2025. From April 15 – December 31, 2025, he spent only 6 days back in the US.
- January 1 – April 14, 2025: 104 days in US (didn’t move yet)
- April 15 – December 31, 2025: 261 days in Mexico, 6 in US, 0 transit = 255 full days in Mexico
Calendar year 2025 has only 255 full days in Mexico — fails PPT.
But David can choose a 12-month window of April 15, 2025 – April 14, 2026:
- April 15, 2025 – December 31, 2025: 261 days in Mexico, 6 in US, 0 transit = 255 days in Mexico
- January 1, 2026 – April 14, 2026 (assume): 104 days in Mexico, 0 in US = 104 days in Mexico
- Total in 12-month window: 359 days ≥ 330 → PPT passed!
David claims FEIE for tax year 2025 with prorated exclusion. Window covers April 15 – December 31 (261 days of 365). Maximum FEIE: $132,900 × 261/365 = ~$93K.
Example 3 — Frequent business traveler back to US
Maria lives in Mexico but consults for US clients and visits the US one week per month (12 weeks total = 84 days).
- 365 – 84 = 281 full days in Mexico
- 281 < 330 → PPT fails.
Maria can’t use FEIE for this year. Options:
- Use FTC instead (claim foreign tax credit on Mexican tax paid)
- Reduce US travel next year (under 35 days) to qualify for PPT
- Use Bona Fide Residence Test if she can demonstrate Mexico is her bona fide residence
Frequently Asked Questions
What is the FEIE Physical Presence Test? The Physical Presence Test (PPT) requires you to be physically present in a foreign country for at least 330 full 24-hour days during any consecutive 12-month period to qualify for the Foreign Earned Income Exclusion. The 12-month period doesn’t have to align with the calendar year.
How do I count days for the Physical Presence Test? A “full day” is a complete 24-hour period entirely outside the United States and US territories. The day you arrive abroad and the day you depart for the US typically don’t count as full days. Layovers in the US or brief US visits disqualify those days.
Does a layover at a US airport disqualify the day for PPT? Yes. Any presence in the US during a 24-hour period disqualifies that day from your “foreign country” count, even brief layovers. Plan flights with non-US transit hubs (Frankfurt, Madrid, Mexico City) to avoid this.
Can I take vacation in the US while maintaining PPT qualification? Yes, up to about 35 days. 365 – 35 = 330 full foreign-country days. More US time means you fail PPT. Plan US visits carefully if you’re close to the threshold.
What’s the difference between Physical Presence Test and Bona Fide Residence Test? PPT is mechanical — count days. BFRT is subjective — facts and circumstances about your residence. PPT is best for digital nomads and recent movers; BFRT is best for long-term established expats. Most newer expats use PPT.
Do international waters count toward the 330 days? No. Days in international waters or international airspace count as 0 toward your 330 — you’re not “in a foreign country” during those days. Cruise voyages and long international flights don’t help your count.
Can I qualify for PPT in my first year abroad? Often yes, with proration. If your move date allows you to choose a 12-month window with 330+ foreign days, you qualify for FEIE in your first year — but with a prorated exclusion limit based on the portion of the 12-month window in that tax year.
Do days in Puerto Rico count as foreign or US? US. Puerto Rico is a US territory; days there count against your foreign-country day count. Same for US Virgin Islands, Guam, American Samoa, Northern Mariana Islands.
What documentation do I need to prove PPT? Day-by-day calendar showing your location each day, supported by passport stamps, boarding passes, hotel receipts, foreign ATM withdrawals, foreign rental contracts. Apps like TripIt help auto-import travel data. Maintain records for at least 3 years (IRS audit window).
What if I fail PPT for one year — can I use FEIE next year? Yes. Each year is independent. If you spent too many days in US this year and failed PPT, simply count more carefully next year. Your prior-year FEIE election (or lack thereof) doesn’t affect future-year eligibility.
