If you meet certain requirements, you may qualify for the foreign earned income exclusion, the foreign housing exclusion, and/or the foreign housing deduction. To claim these benefits, you must have foreign earned income, your tax home must be in a foreign country, and you must be one of the following:

• A U.S. citizen who is a bona fide resident of a foreign country or countries for an uninterrupted period that includes an entire tax year,
• A U.S. resident alien who is a citizen or national of a country with which the United States has an income tax treaty in effect and who is a bona fide resident of a foreign country or countries for an uninterrupted period that includes an entire tax year, or
• A U.S. citizen or a U.S. resident alien who is physically present in a foreign country or countries for at least 330 full days during any period of 12 consecutive months.

You can use the IRS’s Interactive Tax Assistant tool to help determine whether income earned in a foreign country is eligible to be excluded from income reported on your U.S. federal income tax return.
