Dear experts
Im a grad student from Denmark, whos been in the US on a F-1 visa since august 2006.
Due to less than accurate information from the university i seem to have made errors in my filed taxes.
august 2006 - dec. 2006:
I filed my taxes on a 1040EZ, where i should have filed on a 1040NR.
Should i send in a 1040X with a 1040NR attached?
2007:
I got married to an american citizen in 2007, and we filed jointly on a 1040EZ.
I have the option to file as a resident alien because of the marriage, so i might not have done anything wrong. But if i file as a resident alien, i have to include a rental income from Denmark (which i did not), of about 8000$, which ive paid taxes for in Denmark.
So should i send a 1040X with a statement that i want to be a resident alien and include my rental income from Denmark, or can it be negated so i dont have to pay taxes twice?
If i want to stay a non-resident alien, would i have to send in a 1040X for both me and my spouse, plus a 1040NR for me? And would they allow that, since they write that they dont let spouses submit sparately after april 15 if they submitted jointly
Best regards
Janus
