Understanding Self-Employment Tax

Self-employment tax covers the Social Security and Medicare contributions that employers and employees normally split. When you are self-employed, you pay both halves, totaling 15.3% of your net self-employment earnings. This consists of 12.4% for Social Security (up to the annual wage cap) and 2.9% for Medicare with no cap.

Only 92.35% of your net SE income is subject to SE tax, which mirrors the fact that employers pay half of FICA for their employees. Additionally, you can deduct 50% of your self-employment tax from your adjusted gross income, reducing your income tax liability.
