Let’s kick off with one of the most important breaks for US expats, the Foreign Earned Income Exclusion (FEIE). For 2025, you can exclude up to $130,000 of foreign-earned income, which means you avoid paying US tax on most of your salary earned overseas. If you are married and both spouses qualify, your family can double that benefit. To take advantage, you’ll need to qualify under the Bona Fide Residence Test or the Physical Presence Test. The first looks at whether you’re truly settled in your new country for the tax year, and the second counts at least 330 full days you spent outside the US in any 12-month period.
