I have touched on this topic before.
I am married to a Canadian citizen. Her income is under $92,000, and she has no unearned income. We plan to MFJ. (By next year she will be legal resident of the USA anyway.)
1) Is there any reason not to take the FEIC, since it would essentially mean we will pay no tax on her income? The FTC might put us in the same situation, I'm not sure.
2) Are there any implications for future years as to which I use this year? If one method generates lower tax this year, can I switch in future years?
