The Physical Presence Test is one of two ways to qualify for the Foreign Earned Income Exclusion (FEIE) — the provision that lets US citizens and residents abroad exclude up to $132,900 of foreign earned income from US tax in 2026. The test requires you to be physically present in a foreign country or countries for at least 330 full days during any 12-month period. It sounds straightforward, but the day-counting rules, the definition of "full day," and the 12-month period selection contain traps that disqualify thousands of expats every year. This guide covers every detail you need to pass the test.
Physical Presence Test Quick Facts (2026)
- Requirement: 330 full days (24-hour periods) physically present in a foreign country during any consecutive 12-month period
- FEIE exclusion: Up to $132,900 for 2026 (up from $130,000 in 2025)
- 12-month period: Does NOT have to be a calendar year — any 12 consecutive months works
- 330 out of 365: You can spend up to 35 days in the US (or in transit) and still qualify
- Full day: A full 24-hour period (midnight to midnight) — travel days between the US and a foreign country do NOT count
- Multiple countries: Days in different foreign countries can be combined — you don't need to stay in one country
- Form: Claim on Form 2555 (Foreign Earned Income Exclusion)
How the 330-Day Count Works
The Physical Presence Test is purely mechanical — unlike the Bona Fide Residence Test, there is no subjective "intent" analysis. You either have 330 full days or you don't. Here's how to count:
- A "full day" is midnight to midnight. If you depart the US at 11:00 PM on January 1 and arrive in London at 11:00 AM on January 2, neither January 1 nor January 2 counts as a full day abroad. January 3 (your first full midnight-to-midnight day in a foreign country) is when your count starts.
- Travel days between US and foreign countries don't count. The day you leave the US and the day you return to the US are NOT full days in a foreign country. If you fly from New York to Paris, your departure day and arrival day don't count.
- Travel days between foreign countries DO count. If you fly from London to Tokyo, both the departure and arrival days count as full days in a foreign country (you were in a foreign country at midnight on both ends).
- US time counts against you. Every full day spent in the United States reduces your foreign-day count. This includes layovers — if you have a 14-hour layover at JFK, that entire calendar day is a US day if you were in the US at midnight.
- International waters and airspace: Time spent over international waters or in international airspace does not count as time in a foreign country OR in the US. It's a neutral zone.
Choosing Your 12-Month Period
This is where strategic planning pays off. The 12-month period does NOT have to be January 1 to December 31. It can be any 12 consecutive months that contain at least 330 qualifying days. For example:
- February 15, 2025 to February 14, 2026
- July 1, 2025 to June 30, 2026
- March 3, 2025 to March 2, 2026
The period must overlap with the tax year you're claiming the exclusion for. For the 2026 tax year, your 12-month period must include at least one day in 2026. If you moved abroad in November 2025, you could use November 1, 2025 to October 31, 2026 as your 12-month period, claiming a partial-year FEIE for 2025 (November-December) and a full-year FEIE for 2026.
Pro Tip: The 35-Day US Visit Budget
You have exactly 35 days of "slack" (365 minus 330). Most expats use these for holiday visits home, business trips, or medical appointments in the US. Track your US days meticulously — even one extra day can disqualify you and cost you $20,000+ in additional tax on $132,900 of income. Use a travel tracking app or spreadsheet that records every border crossing.
