FEIE 330-day calculator
The Foreign Earned Income Exclusion can shelter most of your earned income from US tax, but only if you clear 330 foreign days in a 12-month window. Enter your US trips and see exactly where you stand.
Your 12-month window
The Physical Presence Test counts 330 full days in a foreign country during any 12-month period. Pick the window you want to test.
Days in the United States
Add each period you spent in the US (or its territories). Everything else in the window counts as a foreign day.

The FEIE 330-day test, in practice
What is the 330-day rule for the FEIE?
To claim the Foreign Earned Income Exclusion under the Physical Presence Test, you must be physically present in a foreign country (or countries) for at least 330 full days during any 12-month period. Miss 330 by a single day and the exclusion is lost for that period.
What counts as a 'full day' in a foreign country?
A full day is a 24-hour period in a foreign country. Days you arrive in or depart the US, days spent in US territory, and time over international waters or airspace do not count as foreign days.
Does the 12-month period have to be a calendar year?
No. It can be any 12 consecutive months, and you can choose the window that maximizes your foreign days, which is exactly what this calculator helps you test.
What's the difference between the Physical Presence Test and the Bona Fide Residence Test?
The Physical Presence Test is a mechanical 330-day count. The Bona Fide Residence Test is qualitative, being a bona fide resident of a foreign country for an uninterrupted tax year, and is usually easier for long-term expats and harder for short-term ones.
