Additional Medicare Tax The Additional Medicare Tax (IRC sections 1401(b)(2) and 3101(b)(2)) applies to individuals’ wages, other compensation, and self-employment income over the applicable threshold; employers are responsible for withholding the tax on wages and other compensation in certain circumstances. The rate of the Additional Medicare Tax is 0.9 percent. The applicable threshold is: $250,000 if married filing jointly; $125,000 if married filing separately; and $200,000 for all other filing statuses.

Additional Medicare Tax (continued) An employer must withhold Additional Medicare Tax from wages it pays to an individual in excess of $200,000 in a calendar year, without regard to the individual’s filing status or wages paid by another employer. An individual may owe more than the amount withheld by the employer, depending on the individual’s filing status, wages, compensation, and self-employment income.
