Filing 2009 US taxes

I just returned from Arizona back to Canada after living and working there for 2 years. I worked for a US employer.
Do I complete a full time resident return in the US for Federal (1040) and State as I was in the US > 183 days? Or do I need to prorate the Itemized deductions for the time I spent in the states.
Does anyone one know which site to use for E filing if I am considered a part time residents. There are many softwares to accommodate full time residency. Much obliged!

You don't prorate deductions in US like in canada.

You should either file dual-status (reverse of when you arrived in US), or file full-year 1040, excluding your Cdn wages with form 2555.

For the state, you file only AZ-source income.

thanks for the assistance.
This web site is so helpful to expats. Unfortunately, having just returned to Canada...do not intend to be an expat in the near future.

Hi all,
I am doing a postdoctoral fellowship in California. I have been there since September 2008 under a J-1 visa. Last year I filled both Canadian an US tax report. I am not sure if I needed to fill the Canadian one, some people told me otherwise. On the other hand, I read that it takes two years to become resident (for tax purpose only) in the US. Therefore I think that I have to fill a 1040NR, this is what I did last year. For next year I would Still fill a 1040NR and then a normal one (resident) and no more Canadians for the following years. Also, if I have to fill the Canadian tax report, do I subtract the taxes amount paid in the US? If I don’t, I will pay a lot of tax, which does not seem to make sense.
Finally, my girlfriend who came with me in California was working under a J-1 for 2009 and will now be under a TN for 2010 (she has a new job). Does the same rule apply? Is she going to restart the two years non resident?

Thank you
