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. But as a self-employed individual, you are considered both the employer and the employee, which makes the entire self-employment tax burden yours.
Self-employment tax is a combined tax consisting of Social Security tax and Medicare tax for people who are self-employed. Instead of having Social Security and Medicare taxes withheld from their earnings like wage earners, self-employed persons must figure and pay their own self-employment taxes. Half of a taxpayer's self-employment tax is allowed as a deduction against self-employment income.
