A new Additional Medicare Tax goes into effect starting in 2013. The 0.9 percent Additional Medicare Tax applies to an individual’s wages, Railroad Retirement Tax Act compensation, and self-employment income that exceeds a threshold amount based on the individual’s filing status.

The threshold amounts are: $250,000 for married taxpayers who file jointly,

$125,000 for married taxpayers who file separately, and $200,000 for all other taxpayers.

An employer is responsible for withholding the Additional Medicare Tax from wages or compensation it pays to an employee in excess of $200,000 in a calendar year.
