Whats the rule for paying taxes while on OPT if you have stayed for more than 5 years? Does one have to pay all the taxes like a resident would pay or is it different? Any one?

hello Max,

Abt me, I am not paying SSN N medicare taxes but Im paying federal and state. Im here more almost 6 yrs. Even when I did worked using my SSN in summer, I didnt paid SSN and Medicare taxes while I paid others. The reason why I didnt paid is beacuse I told my employer that I am student and I wont pay SSN N medicare and they agreed with me. But you need to show the proof why you are not paying the taxes and I printed out this link and showed to my current employer. They agreed with me.

 Thanks for the info. Is there a way i can claim my taxes back which i have already paid for this year in the tax return?

Hello max,
I think You can. I read one of the link that you can fill one of the form and claim and you will get refund. http://www.irs.gov/businesses/small/international/article/0,,id=104936,00.html

There is form in this link where you can ask for refund, This should help you.

Take care...

 Thank you for your help

You're anwered and as you are a student you do not want to whitheld more rather get cash in hand.

But if you are planning to stay longer and eventually applying for GC then you may strart paying taxes medicare as well social security. That will determine your future benifit.
