For 2014, the self-employment tax rate is 15.3 percent. The rate is divided into two parts: 12.4 percent for social security and 2.9 percent for Medicare.

The social security wage base for self-employed individuals in 2010 will also be $106,800. There is no limit on covered self-employment income that will be subject to the Medicare tax. The self-employment tax rate remains 15.3% (combined social security tax rate of 12.4% and Medicare tax rate of 2.9%). In 2010, the maximum social security tax for a self-employed individual will be $13,243.20. This is unchanged from the 2009 maximum.
