Hello,
I came to California from Germany in October 2012 and work here on a H1B visa (I got an SSN) with my wife (H4 Visa, no work). I got a W-2 form from my employer.
I am trying to figure out how to file taxes for 2012.
It seems I have the following two options:
-file a 1040NR stating the U.S. income only. I am required to file "Married filing separately" in this case which gives me less deductions. Probably I need to pay taxes that my employer withheld as I told I was married?
-file a 1040 declaring my world wide income for 2012. Taxes paid on my income in Germany would be subtracted to avoid double taxation? I would need to pay taxes on interest earned which is tax-free below a certain amount in Germany? How to convert Euros in Dollars? I would be able to file jointly in this case, but my wife would need to obtain an ITIN number?
Furthermore I need to disclose any bank accounts I have in Germany and their maximum balance in 2012 to at least two different authorities on different forms?
Is this more or less correct or did I get it wrong?
Also in the US I need to additionally declare for the California state tax to another authority. Are these different forms and if yes, do the same rules apply for a person moving to the US within the year?
How can I find out which of the two options is best for my case? Most tax programs like TurboTax do not support 1040NR therefore I cannot compare.
Any help or hints are very much appreciated.
