Hi,

Please help me out. I graduated in May 2011 and had been working part time on campus till that time. I got a full time job in July 2011 and I requested my employer to not withhold social security, medicare, etc. Since I'm on F1-visa. However I just learnt about the "5 year exemption" rule. My 5 years in the US on F1 visa ended July 2011. So my employer should have withheld FICA taxes starting August 2011, but has not due to my request. I will be asking my employer to withhold FICA taxes starting Nov 2011.

Following are my questions:
1) Will I have to pay FICA taxes for the months starting August 2011, when I fill out my tax return forms? If so, what is your estimated amount that I will have to pay?

2) I heard that employer pays a partial amount of FICA taxes. Will I have to pay the full amount of FICA taxes for the months of Aug-Oct 2011 since they weren't withheld by my employer?

3) What is the total estimated refund I can expect ?

Thank you so much for your help.
