If you’re a US citizen or green card holder living abroad, you still file a US return every year, but that doesn’t mean you owe US tax. The two main tools, the Foreign Earned Income Exclusion (Form 2555) and the Foreign Tax Credit (Form 1116), can each reduce your bill to zero. Picking the wrong one, though, can cost you real money and switching later locks you out of the exclusion for five years.
The right answer depends on where you live. High-tax countries like Japan and Portugal usually favor the credit. Lower-tax situations in Mexico often favor the exclusion. Self-employed? There’s a 15.3% trap waiting that neither one fixes, and whether you can escape it depends entirely on your country.
This planner runs your numbers in about two minutes. You’ll see an estimated side-by-side comparison, country-specific flags for Japan, Portugal, and Mexico, and a checklist of the forms you likely need — including FBAR and FATCA reporting that most expats don’t find out about until the penalty letter arrives.
