Can a US Citizen married to a foreign government official working in the US be able to file jointly and exempt her income?
I am a US Citizen married to a Canadian Military Service Member who is on assignment here in the United States (she is a nonresident alien). To my understanding she would not pass the substantive presence test because since she is on a NATO visa her time in the US is considered “temporary”. In addition based on some IRS publication 901 , my understanding is that her income is exempt from US taxes , however if I file married filing jointly , would she still be exempt from those taxes? The way I read it , to file MJF I would have to send a declaration statement declaring my wife as a US resident. If I do that , is she still exempt from US taxes on her income based on the fact she works for a foreign government? Or does that go away?
