Quick answers
What is the 330-day rule?
You need 330 full days in foreign countries within 12 months in a row. That period can cross calendar years, but must include part of the tax year you are claiming for. FEIE also requires foreign earned income and a foreign tax home.
What is a full foreign day?
A full day runs from midnight to midnight in a foreign country or countries. US arrival and departure days usually do not count. Some travel exceptions apply.
Do flights and layovers count?
On direct US–foreign trips, time over international waters does not count. Between foreign countries, travel outside those countries lasting less than 24 hours generally does not lose full days. Short US layovers have special rules this tool does not handle; check with your tax advisor.
What if I have fewer than 330 days?
Another 12-month period may work. The Bona Fide Residence Test is also a separate route based on where and how you live, including a stay covering a full tax year. Ask your tax advisor which applies.
Does FEIE cover all income?
No. It covers qualifying foreign earned income, such as pay for work abroad. Investment income, capital gains and pensions are not covered.
Can I see a simple example?
In a 365-day period, 20 US days and two transit days leave 343 full foreign days. Ten more US days in that same period, with no overlap, leave 333. Future days still depend on your travel.
Is this free without the app?
Yes. The calendar, trip planner, PDF summary and backups are free. No account or app needed.
How do I check a future US trip?
Confirm your history, then add dates under “Can I take this US trip?” You will see the count before and after. Check the assumptions shown with the result.
Can I share this with my accountant?
Yes. Print or save the summary as a PDF. Keep tickets, passport stamps and other travel records too. The summary is a planning aid, not a tax form or proof of location.
Are my travel details private?
Your dates, notes and results stay in your browser unless you share a downloaded file. We measure basic tool use, but do not send your travel details to analytics.
