You make the call

Question: Your client moved overseas and is asking you to prepare his tax return. The client is a U.S. citizen now living in France. Should you file a Form 1040, U.S. Individual Income Tax Return, or Form 1040-NR, U.S. Nonresident Alien Income Tax Return?

Answer: You will file Form 1040, U.S. Individual Income Tax Return. Form 1040-NR is for individuals who are nonresident aliens. Form 1040 is for U.S. citizens or resident aliens regardless of whether they reside inside or outside the U.S.
