FICA taxes on Bonus for non-resident alient on OPT
Hi,
I have a couple of questions. I am a non-resident alien who finished his MBA in May 08 and started job in July 08 on F1 visa(OPT). My status will switch to H1B visa from Oct 1 08.
1) What are the tax rates on Moving Bonus(lump sum) and Signing bonus ? Do I have to pay FICA tax(SS and Medicare) on these ? The HR was saying that the bonuses will be taxed at 48% flat. Is that correct ?
2) If the Signing bonus is taxed at regular rates, and if I get it after oct 01 08(havent got it yet although it was supposed to be given with first paycheck), will I be paying FICA taxes on it ?
Will appreciate a response,
Thanks
