A U.S. citizen or resident alien’s worldwide income is generally subject to U.S. income tax, regardless of where they live. They’re also subject to the same income tax filing requirements that apply to U.S. citizens or resident aliens living in the United States.
U.S. citizens and resident aliens must report unearned income, such as interest, dividends, and pensions, from sources outside the United States unless exempt by law or a tax treaty. They must also report earned income, such as wages and tips, from sources outside the United States. An income tax filing requirement generally applies even if a taxpayer qualifies for tax benefits, such as the Foreign Earned Income Exclusion or the Foreign Tax Credit, which substantially reduce or eliminate U.S. tax liability. These tax benefits are only available if an eligible taxpayer files a U.S. income tax return.
A taxpayer is allowed an automatic 2-month extension to June 15 if both their tax home and abode are outside the United States and Puerto Rico. Even if allowed an extension, a taxpayer will have to pay interest on any tax not paid by the regular due date of April 18, 2022.
Those serving in the military outside the U.S. and Puerto Rico on the regular due date of their tax return also qualify for the extension to June 15. IRS recommends attaching a statement if one of these two situations apply.
