FICA taxes for foreigners
I am the business manager for a small u.s.business in NYC. We have an employee from England on an L1 Visa and another from Australia on an E3 Visa. Recently, the employee with the E3 (who is relatively new) asked why she has to pay Social security and unemployment taxes since she will never benefit from these. Can someone give me some advice about answering this and where to find it spelled out if it is. I have googled quite a bit and haven't found anything totally clear. Also, if I find that these employees are exempt, how do I work with my payroll company to change how they are set up on payroll and will I need for the employees to get any other paperwork to turn into the payroll agency? Also, will they then be able to file to receive reimbursments from the gov't for the years already paid?
