What is Self-Employment Tax?
Self-employment tax covers Social Security and Medicare taxes for individuals who work for themselves. In 2026, it’s 15.3% of net earnings. As a business owner, you pay both the employer and employee portions, but you can deduct half this tax from your income taxes. The IRS explains self-employment tax in detail.
You owe this tax if your self-employment net earnings exceed $400, whether you’re full-time or just have a side gig.
- Sole proprietors
- Independent contractors
- Gig workers & freelancers
- LLC/partnership members (unless taxed as S corporation)
