I'm a US citizen who got married last year to a Canadian. For the entirety of 2017 we've each been working in our respective home countries and have been living separately since tying the knot until we get emigration items addressed. Seeing how she has no US income and I have no Canadian income, would either of us need to file our tax returns as anything other than "single" this year in our home countries? I don't know what the requirements are as far as what each of us needs from the other with our respective governments and filing taxes this year, if we should each be filing "single" due to there being zero overlap on finances or expenditures, or if we would be legally required to file as "married filing separately". If anyone has any words of wisdom (or a handy FAQ on the topic) it would be most appreciated.
