SS/Medicare refund on OPT
Hello,
I entered US in August 2001. I was on my OPT (Student VISA) till Oct 2004 and then on my H1B. My Social Security and Medicare were deducted on my OPT . For my 2004 tax return I filed 1040A form. I used the software taxact and I did not realize that I have to file 1040NR.
To get the refund for my SS and Medicare deductions, I filed form 843. I did not hear from IRS on refund so I called them and found that they have rejected my 843 refund case because I did not find 1040 NR form.
What do I do now. How do I revert the tax return I filed. Can I file 1040X.
Please advice.
Thank you,
JP
