How self-employment tax works

SE tax is the self-employed version of the Social Security and Medicare taxes an employer would normally split with you — 15.3% on 92.35% of your net profit (Social Security applies up to an annual wage cap; Medicare has no cap). You also owe regular income tax on top, which is why we include an income-tax-rate field. Half of your SE tax is deductible against income tax, and that's reflected here.

Estimate only — not tax advice. Brackets, caps and deductions change and vary by situation and state. Confirm with a tax professional or the IRS.
