The additional tax rate is 0.9% on employee income (employers do not have to contribute to this additional tax). The additional Medicare tax is effective for income over a specific level, depending on the individual's federal income tax filing status.

The law also requires you to pay the employer's portion of two of these taxes: 1  a 6.2 percent Social Security tax; and. 2  a 1.45 percent Medicare tax (the âregularâ Medicare tax).nlike the other FICA taxes, the 0.9 percent Medicare surtax is imposed on the employee portion only. There is no employer match for the Medicare surtax (also called the Additional Medicare Tax). You withhold this 0.9 percent tax from employee wages and you do not pay an employerâs portion.
