Medicare Part B

This is the part you pay for each month which is withheld from your social security payment. If your income is less than $85,000 and you file a single return, or if your income is less than $170,000 and you file a joint return, then the monthly premium is $99.90. If you make over those amounts, then your monthly premium increases from $139.90 to a maximum of $319.70 for 2012. It is like a little mini tax return.
