About This Calculator

Self-employment income is taxed differently than W-2 wages — you owe both the employee AND employer portions of Social Security and Medicare (15.3% combined), plus income tax. This calculator estimates your total tax burden on side income after business expenses.

Estimates only — not financial, tax, legal, or investment advice. Verify important results with a qualified professional before making decisions.

SE tax = net income × 0.9235 × 0.153; income tax = (net − SE tax/2 − expenses) × rate
