Physical presence test: 330-day rule for US expats

Written by  Andrew Coleman, CPA

Last updated Aug 28, 2026

The physical presence route can help qualifying Americans abroad claim FEIE for 2025 if they meet the 330-day rule, have a foreign tax home, and satisfy the other Section 911 rules. The 2025 maximum exclusion is $130,000 per qualifying person.

Physical presence test at a glance

For the 2025 tax year, the physical presence rule requires at least 330 full days in one or more foreign countries during a valid 12-month period. The physical presence test USA standard can support FEIE eligibility, but a foreign tax home and the other Section 911 rules still apply.

Count at least 330 full days in foreign countries during 12 consecutive months that overlap 2025. Meeting the day count supports one FEIE route; it does not replace the foreign-tax-home or eligible-income rules.

The following 4 points cover who can use the test, what counts, and the mistakes that most often change the result:

• US citizens and resident aliens can use this route. For the broader filing context, see US expat tax rules for 2025 returns filed in 2026.
• A counted day must run from midnight to midnight in a foreign country. Partial US travel days usually do not count.
• The 330 days do not have to be consecutive, but all counted days must fall inside one valid 12-month period.
• Do not assume time outside the mainland United States is enough. US territories and international waters are not foreign countries for this test.

For 2025, a qualifying taxpayer may exclude up to $130,000 before any required proration. See how the FEIE works for Americans abroad before treating the day count as the only eligibility rule.

What is the physical presence test?

The IRS physical presence test is a day-count route for US citizens and resident aliens working abroad. Under the US physical presence test, you need 330 full foreign-country days within 12 consecutive months that overlap the 2025 tax year; intent to settle abroad is not part of this test.

It is a mechanical presence test under Section 911. Your reason for being abroad does not control the result; the location and length of your physical presence do.

The following 3 parts explain the rule and its connection to the IRS form numbered 2555:

1. Who can use it: US citizens and resident aliens may qualify if their tax home is in a foreign country during the qualifying period.
2. Day threshold: You need at least 330 full days in one or more foreign countries.
3. Measurement period: The 330 days must fall within any 12 consecutive months that include part of 2025.

This test is not the same as US tax residency or bona fide residence. See how bona fide residence differs from the physical-presence day count before choosing a Section 911 qualification route.

Physical presence test requirements

The physical presence test for taxes has 4 day-count criteria: eligible taxpayer status, presence in foreign countries, 330 full days, and a valid 12-month period. A 2025 FEIE claim also requires a foreign tax home, so passing the day count alone does not establish the exclusion.

The following 4 conditions define the day-count route for a 2025 claim:

• Eligible taxpayer: You are a US citizen or resident alien.
• Foreign-country presence: Your counted days are spent in one or more foreign countries.
• 330 full days: At least 330 days meet the midnight-to-midnight standard.
• Valid 12-month period: The counted days fall within 12 consecutive months that overlap 2025.

A foreign tax home is a separate FEIE requirement. Your tax home is generally your main place of business or work; an abode in the United States can prevent qualification even if your travel calendar reaches 330 days.

The key decision rule is 330 full foreign-country days inside 12 consecutive months, plus a foreign tax home for FEIE.

The IRS recognizes limited exceptions. Adverse-condition and travel-restriction exceptions have separate rules, so a family emergency or ordinary employer request to return to the United States does not by itself waive the 330-day threshold.

Use this 4-step yes/no decision tree before moving on:

1. Are you a US citizen or resident alien? If no, this Section 911 route does not apply.
2. Do you have a foreign tax home? If no, stop and review the tax-home rules.
3. Can you document 330 full foreign-country days in 12 consecutive months? If no, test another window or another qualification route.
4. Does that period overlap 2025? If yes, you may have a qualifying day-count period.

Older edge cases are covered in the TFX physical presence FAQ, but current IRS guidance should control if an older example conflicts with a 2025 rule.

The 330-day requirement explained

The 330-day rule is strict: qualifying days need not be consecutive, but each counted day must be a full foreign-country day inside one chosen 12-month period. The 183-day rule is a different US tax-residency concept and does not reduce the FEIE threshold from 330 days.

Use this formula: qualifying full foreign-country days ≥ 330 within 12 consecutive months. The remaining 35 days are not automatically “US days” because nonqualifying time can also include international waters, US territories, Antarctica, or partial travel days.

Based on our client scenario at TFX: Maya selects July 10, 2024, through July 9, 2025. She documents 332 full days in foreign countries, 20 full US days, and 13 travel or other nonqualifying days. She passes because the foreign-day count is at least 330.

A day counts only if the full midnight-to-midnight period satisfies the foreign-country rule.

A one-day error can turn 330 into 329. If your itinerary is close to the threshold, compare it with TFX examples of the 330-day calculation and verify each entry and exit date rather than counting nights away.

Income timing is a separate issue from the day count. See how to report the timing of overseas income and foreign taxes when pay periods, bonuses, or foreign tax payments cross tax years.

NOTE! Do not count a partial arrival or departure day merely because most of that day was spent abroad. At a 330-day total, one off-by-one error can change qualification.

What counts as a “full day”?

A full day means a continuous 24-hour period from midnight to midnight while you are physically present in a foreign country. For the 330-day test, a day arriving from or departing for the United States usually does not count, while a complete midnight-to-midnight foreign-country day normally does.

The following 4 examples separate countable full days from noncountable partial days:

A full day must stay within qualifying foreign-country presence for the entire midnight-to-midnight period.

Based on our client scenario at TFX: Noah lands in Madrid from New York at 7 a.m. on March 3, 2025. March 3 does not count, but March 4 can count if he remains in a foreign country from midnight through the following midnight.

Rule summary: A counted day is about physical location for the full 24 hours, not where you sleep, work, pay tax, or hold a visa.

Which countries and territories count as foreign?

Only days spent in a “foreign country” count toward the 330-day threshold. For Section 911, this means territory under a sovereignty other than the United States; US territories, international waters or airspace, Antarctica, and areas outside foreign territorial waters do not qualify.

For the 330-day test, a foreign sovereignty can qualify; US territories and international areas do not.

For a mixed itinerary, record where you were at each midnight and whether the full day stayed within qualifying foreign territory. Being outside the continental United States is not enough.

How flights, layovers, and transit days affect your count

Flights and layovers matter because only full foreign-country days count toward 330. A US arrival or departure day normally fails the midnight-to-midnight rule, and international waters do not count; an under-24-hour US transit rule can apply between 2 points outside the United States.

Based on our client scenario at TFX: Lena leaves Boston on April 1, 2025, lands in Lisbon on April 2, and remains there. April 1 and April 2 do not count as full foreign days; April 3 is the first full day that can count.

The following 4 travel rules cover common flight and layover patterns:

• Do: Count a full day spent entirely in one or more foreign countries when no disqualifying transit occurs.
• Do: Keep exact local arrival and departure dates, not only ticket purchase dates.
• Don’t: Count a day spent partly in the United States as a normal foreign full day.
• Don’t: Treat hours over international waters or airspace as presence in a foreign country.

NOTE! “In transit” does not automatically mean “countable.” The 24-hour transit rule and the midnight-to-midnight foreign-country rule answer different questions.

A few examples make the rule easier to apply:

Three travel patterns show how timing changes the 330-day count. A same-day border crossing can lose a day, an overnight flight can create a nonqualifying transit day, and a long assignment can qualify at exactly 330 full foreign days when every counted date meets the midnight-to-midnight rule.

Each scenario below gives a yes/no result based on the same 330-full-day standard.

Our FEIE denial case study shows why documentation and the other eligibility rules matter even when a travel calendar looks strong.

For the IRS reporting layout, the 2025 instructions for the Section 911 filing form explain the physical-presence period and travel schedule used to support the claim.

Choosing your 12-month period

You may choose any 12 consecutive months that contain at least 330 full foreign-country days and overlap the 2025 tax year. The period can begin on any calendar day, need not match January through December, and can overlap another qualifying 12-month period if that produces a larger 2025 exclusion.

Based on our client scenario at TFX: Eli moves abroad on September 20, 2024, and has several US visits in early 2025. A January–December 2025 count is weak, but September 21, 2024, through September 20, 2025, produces 334 full foreign days.

Test more than one rolling window because a custom 12-month period can produce a larger 2025 qualifying-day count.

The IRS Publication 54 rules for the qualifying period allow the 12-month period to begin on any day and permit overlapping periods. Choose the window that gives the strongest valid result for the tax year.

If you need more time to meet the day test before filing, review when Form 2350 can extend the filing date for FEIE qualification. It extends filing time in qualifying cases, not the deadline to pay tax.

What if you qualify for only part of the tax year?

If your qualifying period covers only part of 2025, the $130,000 maximum exclusion is prorated by the number of qualifying days that fall in 2025. The basic calculation is $130,000 × qualifying 2025 days ÷ 365, subject to your actual eligible work income and any housing exclusion interaction.

Based on our client scenario at TFX: a taxpayer has 140 qualifying days in 2025. The maximum before eligible-income limits is $130,000 × 140 ÷ 365 = $49,863 after rounding to whole dollars.

The FEIE form uses qualifying days that fall inside the tax year to compute the fraction. See the TFX guide to the FEIE filing form for the line-by-line mechanics.

A partial-year period does not mean you can exclude 2025 pay earned outside the qualifying dates. Review the 2025 FEIE rules and $130,000 limit when matching work income to the qualifying period.

The IRS filing-form guidance for the exclusion confirms that the qualifying test and calculation are filed with the federal return. A period that starts or ends midyear can still work if the selected 12 months contain 330 full foreign days.

Partial-year qualification can change your 2025 exclusion. Get the return handled correctly.

Physical presence vs bona fide residence

For a short assignment, the 330-day route is easier to document because it depends on days, not intent. Bona fide residence generally fits settled living abroad and requires an uninterrupted period including a full tax year, with stricter eligibility rules for a resident alien for tax purposes.

A US resident for tax purposes should not confuse either Section 911 route with the separate substantial presence test used to determine US tax residency. The physical-presence and bona fide-residence tests instead help determine eligibility for Section 911 benefits.

The 330-day route fits date-driven assignments; bona fide residence fits taxpayers who can prove settled residence for a full tax year.

US citizens may use either route if they meet its rules. Some resident aliens can use bona fide residence only if they are citizens or nationals of a country with the required US income tax treaty; the physical-presence route is broader.

See the TFX bona fide residence guide for the facts used to evaluate settled overseas residence. The IRS bona fide residence rules explain the full-tax-year requirement and treaty-country restriction for qualifying resident aliens.

Which test should I choose?

Choose the 330-day route when a 12-month calendar clearly gives you at least 330 full foreign-country days. Consider bona fide residence when you are settled abroad for a full tax year and your facts support residence; frequent US trips alone do not create a fixed-day limit under that test.

Use the following 4-question decision tree to pick the better route for your facts:

1. Can a 12-month window give you 330 full days? Test the day-count route first.
2. Do you travel frequently? Use a day-by-day calendar to see whether 330 full days remain.
3. Are you settled abroad for a full tax year? Review bona fide residence and your foreign-country ties.
4. Is the day count uncertain? Do not assume bona fide residence is automatic; test its separate requirements.

For a short fixed assignment, the day-count route is usually clearer. For long-term settled living, bona fide residence may allow more US travel without a fixed 330-day threshold, subject to the facts.

After choosing a qualification route, compare the tax result. Our FEIE versus Foreign Tax Credit guide explains why the better tax method can depend on foreign tax rates, income type, and credit eligibility.

Foreign Earned Income Exclusion (FEIE) and physical presence test

Passing the 330-day test can satisfy one residence-based route to FEIE, but it does not by itself create an exclusion. For 2025, you also need a foreign tax home and eligible work income, and the maximum exclusion is $130,000 per qualifying person before any required proration.

The following 4 points show what passing the day test does and does not establish for FEIE:

• It does: Provide one way to satisfy the Section 911 residence/presence requirement.
• It does: Support a prorated exclusion when only part of 2025 falls in the qualifying period.
• It does not: Prove that your tax home is abroad.
• It does not: Convert pensions, investment returns, or other non-work income into eligible pay.

The IRS FEIE eligibility rules also require a foreign tax home and qualifying earned work income. Meeting 330 days while keeping an abode in the United States can still create a tax-home problem.

Key point: Passing 330 days is necessary for this route, but it is not sufficient by itself. The $130,000 2025 cap applies only after the other Section 911 conditions are met.

Key FEIE details

For a 2025 claim, Form 2555 attaches to your federal return and records the qualifying test, tax home, travel period, eligible income, and exclusion calculation. Part III covers the 12-month physical-presence period and travel schedule; Part VII calculates the exclusion, capped at $130,000.

The following 4 filing details matter most for 2025:

• Qualifying income: Wages, salary, and self-employment income for services performed abroad can qualify; passive income does not.
• Tax home: Your main work location must be in a foreign country during the qualifying period.
• Timing: Only qualifying days that fall in 2025 enter the annual proration calculation.
• Records: Your return position should be supported by travel and tax-home documentation.

The filing form reports the claim, while your records support the facts behind the claim.

How to calculate your 330 days

Start with a 12-month window, list every location by date, and count only midnight-to-midnight days in foreign countries until you reach 330. No IRS physical presence test calculator replaces your records; use a travel log that traces each counted day to tickets, stamps, and other proof.

Use the following 5-step method to reproduce the count:

1. Pick a proposed 12-month start date.
2. List your country or travel status for every calendar date.
3. Mark only midnight-to-midnight foreign-country days as qualifying.
4. Remove US days, partial travel days, and non-foreign locations.
5. Total the qualifying days and test other windows if the result is below 330.

Based on our client scenario at TFX: a travel log shows 328 qualifying days from August 1, 2024, through July 31, 2025. Moving the window forward 6 days captures 4 later foreign days and drops 2 US days, raising the count to 334.

Your spreadsheet should show each date, location, count status, and the reason for that status.

Keep the underlying documents with the calendar. The TFX guide to preserving tax and financial records explains why the support behind a return matters as much as the spreadsheet total.

Check whether your US days could make you a tax resident.

What records to keep

Keep records that support every claimed day in your 12-month period and the foreign tax home behind your 2025 FEIE position. A practical file should include 5 record types: passport evidence, tickets, travel calendars, immigration documents, and employment records tied to your overseas work dates.

The following 5 record types create a practical audit-support file:

• Passport entry and exit stamps, where available.
• Boarding passes, e-tickets, and airline itinerary receipts.
• A dated travel calendar showing each country and transit day.
• Visa, residence permit, or immigration documents tied to the stay.
• Employer assignment letters, contracts, or work-location records.

A simple travel log can use 4 columns: date | country/location | full day? | supporting document. Add a short note for any date involving a US stop, cruise, long flight, or disputed arrival time.

IRS recordkeeping guidance generally uses a 3-year limitations period for a normally filed income tax return, with longer periods in some cases. See the TFX tax documents checklist for a broader filing file.

Physical presence test examples

These 4 scenarios cover a clean pass, a rolling-window pass, an exact-threshold case, and a near-miss. Each uses a 12-month period and counts only full days in foreign countries, so the result turns on documented dates rather than intent, visa status, or the reason for travel.

A pass requires at least 330 qualifying full days; 329 is still a fail unless a valid exception applies.

Based on our client scenario at TFX: the near-miss taxpayer first counted an arrival day and reached 330. Removing that partial day reduced the total to 329, so the original window failed; a different rolling window had to be tested.

Conclusion

For a 2025 FEIE claim, the core rule remains 330 full foreign-country days within a qualifying 12-month period, plus a foreign tax home and the other Section 911 conditions. Choose the strongest rolling window, verify every travel day, and keep records that can support the count if the IRS asks.

The following 3 final checks should be completed before claiming the benefit:

• Confirm the chosen 12-month period contains at least 330 full foreign-country days.
• Confirm your foreign tax home and qualifying work-income facts for the same period.
• Save the travel calendar and records that support every close or unusual date.

Final takeaway: One verified 12-month window, one defensible 330-day count, and one complete record file are the practical foundation for a 2025 claim.

Physical presence test checklist

A final 5-point check can catch most day-count problems before you file your 2025 return. Confirm 330 full days, foreign-country location, a foreign tax home, a valid 12-month period, and records for each trip; if any answer is “no,” review the facts before claiming the exclusion.

Use the following 5 yes/no items as a printable pre-filing check:

• 330 days: Do you have at least 330 full qualifying days?
• Foreign location: Was each counted day in one or more foreign countries?
• Tax home: Was your tax home abroad throughout the qualifying period?
• 12-month period: Do the days fit inside one valid 12-month window that overlaps 2025?
• Records: Can you support close travel dates with a calendar and source documents?

If every answer is yes, review the FEIE calculation and filing form. If an answer is no or uncertain, use the FAQ below to identify the rule that needs a closer check.
