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 Internal Revenue Service imposes a self-employment tax on self-employed individuals. This self-employment tax consists of a Social Security tax and a Medicare tax. Normally, self-employed individuals must pay a Social Security tax of 12.4 percent on the first $106,800 of income. However, the 2010 Tax Relief Act has temporarily lowered the Social Security Tax to 10.4 percent.
