F-1 Student who filed 1040ez form on taxact.
From what I have researched on Google, I understand that filing 1040ez when on F-1 visa in the US for less than 5 years is wrong.
I came to the US in aug 2008. I have an on-campus job, so filed 1040NR-EZ from my univ software (for FY 2008). Till date I am on F-1 visa, studying here.
For FY 2009, I filed my taxes online at taxact.com, because, apparently taxact.com has a higher amount of refund for F-1 students(reason that I did not know why). After filing it, I got back the 1040EZ form with my refund amount. Seems like e-file is not for f-1 students present in the US for less than 5 years.
1.) I should have filed 1040NR-EZ form, yes or no?
If yes,
2.) I have got back my taxes for the year 2009, if 1040EZ is the wrong form what is my next step. Could someone guide me regarding the amendment letter, what to do, where to send and stuff.
3.) OK fine, I have filed my 1040EZ form and got back extra cash. I like that. I don't feel like giving back that money now, will this be a problem in the future that I filed taxes like a resident (1040EZ)? If so, how? (General knowledge question so that I can help my juniors or anyone else who made the same mistake like me.)
