I am a US citizen with no overseas income of any kind. I am considering marrying a Canadian citizen with no income of any kind outside Canada. She might stay in Canada for a while after the marriage.
Revenue Canada tells me it would have no effect on her taxes - good. The IRS tells me that she can elect to be treated as a nonresident alien, but then I have to file as married filing separately - bad!
If she elects to be treated as a resident alien, what happens to her income and to the taxes she pays to Canada?
In case it matters, her income is about $CDN 70,000.
Thanks in advance for any help.
