The Tax Surprise Every New Freelancer Faces
You landed your first freelance client. Then tax season hits and you discover you owe 30–40% of that income to the government — not the 22% you expected from looking at income tax brackets.
The extra is self-employment tax: 15.3% on top of income tax, covering the Social Security and Medicare taxes that your employer would have split with you.

How Self-Employment Tax Works
SE tax applies to your net self-employment income (revenue minus business expenses):
- 12.4% for Social Security (on income up to $168,600 in 2024)
- 2.9% for Medicare (no income cap)
The IRS applies SE tax to 92.35% of net income (equivalent to excluding the employer's share).
Example: $80,000 net SE income × 0.9235 × 15.3% = $11,304 SE tax

Strategies to Reduce SE Tax
Maximize business deductions: Every legitimate business deduction reduces net income, lowering both SE tax and income tax.
S-Corp election: Once income exceeds ~$80,000 consistently, splitting it between salary (SE-taxed) and distributions (not SE-taxed) can save $5,000–$15,000+ annually.
SEP-IRA or Solo 401(k): Reduces income tax liability while building retirement savings. A solo 401(k) allows up to $69,000 in contributions in 2024.
