Duel Status anyway but SST refund
I already filed 2005 tax return as a duel status.
I got already refund what I filed.
After that, I claimed my SST/Med for a partial year. My employer already deducted its tax during my F-1 period.
I got it denied because it appeared 1040.
I explained my status as a duel on the phone, but he told me that I could not clain SST refund.
So, my questions are;
After filing a duel status, can I claim SS/Med tax refund or not?
Can I submit a amended file as 1040NR tax return so that I claim SS/Med tax refund later?
Right now, it seems I supposed to submit tax return as a NR. Do I have to file amended tax return as a NR?
Now, I am confused what to do.
Please let me if you have any idea.
