When comparing a $100k freelance contract to a $100k salary, the freelance option carries significantly higher tax costs — but also higher pre-deduction income. Here's the full picture.
The Core Difference: SE Tax
A W-2 employee at $100k pays: - Social Security (6.2%) + Medicare (1.45%) = 7.65% from their paycheck - Employer pays a matching 7.65% (invisible to the employee)
A freelancer at $100k net profit pays: - Both sides: 15.3% SE tax ($15,300) - Can deduct half ($7,650) from taxable income
So the self-employed person pays ~$7,650 more in employment taxes than the equivalent W-2 employee at the same income level.
The Rate Differential
| Income | W-2 Employee | Freelancer |
|---|---|---|
| $60,000 | ~$9,000 total tax | ~$16,000 total tax |
| $100,000 | ~$18,000 total tax | ~$28,000 total tax |
| $150,000 | ~$32,000 total tax | ~$44,000 total tax |
Estimates for single filer, standard deduction, no other income.
Why Freelancers Often Come Out Ahead
- Higher gross rates: Contractors typically earn 20–40% more than employees for equivalent work (no benefits cost to the company).
- Deductions: Business expense deductions reduce taxable income below the W-2 equivalent.
- Retirement accounts: SEP-IRA and Solo 401(k) let freelancers shelter far more than the W-2 $23,000 401(k) limit.
- Flexibility: You can choose when to recognize income, defer to lower-income years, or accelerate deductions into high-income years.
The Break-Even Analysis
If an employer offers $100k W-2 vs. $115k freelance contract: - Extra SE tax ≈ $7,650 - Extra income: $15,000 - Net advantage of freelance: ~$7,350 before deductions
Add deductions (home office, health insurance, retirement) and the freelance option is usually significantly ahead at $115k vs $100k.
