How this calculator works
Estimates self-employment tax (Social Security and Medicare equivalent) owed by independent contractors, freelancers, and sole proprietors.
Formula
Taxable SE Base = Net Business Income × 92.35%; SE Tax = Taxable Base × 15.3%
Worked Example
$80,000 gross freelance income minus $10,000 business expenses = $70,000 net earnings. Taxable SE base = $64,645. SE Tax at 15.3% = $9,890.69.
Assumptions
- Applies standard 15.3% self-employment rate (12.4% Social Security + 2.9% Medicare).
- Net business earnings equal gross revenue minus ordinary business expenses.
Limitations
- Does not calculate federal/state income taxes, municipal tax compliance, or quarterly underpayment penalties.
