What is self-employment tax?
Self-employment tax (definition)
Self-employment tax is the name given to Social Security and Medicare taxes when paid by a self-employed person. For employees, the employer shares the cost of these two taxes with the employee. But self-employed workers have to pay both shares.
If your net earnings as a self-employed person are $400 or more during the tax year, you have to pay self-employment tax. The employer half of the self-employment tax is a tax-deductible expense that you can claim separately on your income tax.
