Starting with your 2013 income tax, a new Medicare tax may apply to you if you work and make more than certain amounts. It will not apply to most workers.
The new Medicare tax rate is 0.9% of wages, compensation, and self-employment. This is in addition to the regular Medicare tax you already pay.
If you are a single taxpayer, the new tax applies to any amount you make over $200,000. If you’re married and filing jointly, the tax applies to any amount you both make over $250,000. For those married and filing separately, the tax applies to any amount over $125,000.
If you owe the tax, you’ll report it on Form 8959. Your employer will withhold additional Medicare tax for all pay over $200,000.
