I am a Canadian citizen who moved from BC to the US to be married in July 2005. My income was from 100% Canadian sources in 2005. After speaking with the International tax office of Revenue Canada, I'm clear on how I have to file my taxes. They also told me that, as I withdrew an RRSP in December 2005, I had the option of requesting a "partial year 217" when I file my 2005 taxes to try to recoup some of the 25% non-resident tax taken on that. I was told to file my BC tax forms and then attach a letter to them that stated 1) my 2005 income was from at least 90% Canadian source and 2) that I was requesting my RRSP withdrawal after leaving Canada to be considered under a partial year 217.
So, just for fun

, I have completed my taxes and then did a few very basic calculations on a non-resident set of forms to see what the difference would be. The only thing of which I'm unsure is, on these non-resident forms it used my husband's world income in determining some of the credits. My questions are:
1) On a partial year 217 would they still consider my husband's world income? Would it be somehow prorated? If they do consider that income, how do they verify what I say is correct (i.e. do I need to send a copy of our jointly-filed US taxes or W2 or ???)?
2) If I choose to request them to review it for partial year 217, I'm assuming that I would send my NR4 to them for that purpose. Is that correct?
My apologies if this has been asked already...if so, please point me to the link! Thanks!!!
