Unless one or the other of you (employer or employee) are confusing the SS and Medicare taxes (FICA) with the regular "income" taxes.
Do your paystubs actually list the SS and Medicare taxes separately (FICA taxes) from the Federal Income taxes withheld?
I'm pretty sure the FICA taxes go to the IRS too, at least at first, and then they credit the SS/Medicare agencies the proper amounts. i.e the employer sends both the FICA taxes and regular income tax withholding to the IRS
