The biggest tax shock for new freelancers is discovering they owe significantly more in taxes than they did as employees. The culprit is self-employment tax — the 15.3% that hits every dollar of freelance income before income tax even enters the picture. Here's exactly how it works and what you can do about it.
What Employees Pay vs. What Freelancers Pay
When you're a W-2 employee, your employer pays 7.65% of your salary toward Social Security (6.2%) and Medicare (1.45%). You pay the other 7.65% through payroll withholding. Together, these 15.3% in FICA taxes fund Social Security and Medicare.
When you're a 1099 freelancer, there's no employer to cover half. You pay the entire 15.3% yourself. This is called self-employment tax, and it's reported on Schedule SE when you file your return. On $80,000 of net freelance income, that's roughly $11,300 in self-employment tax alone — before income tax.

The IRS provides a small break: you only pay SE tax on 92.35% of your net earnings (not the full amount). This 7.65% reduction mirrors the fact that employees don't pay FICA on their employer's FICA contribution. On $80,000, your taxable base is $73,880 rather than the full $80,000.
The Half-SE Deduction
You can deduct half of your self-employment tax from your adjusted gross income. This doesn't reduce your SE tax, but it does reduce your income tax. It's an above-the-line deduction, meaning you get it regardless of whether you itemize or take the standard deduction.
Social Security Wage Cap
The 12.4% Social Security portion of SE tax only applies to earnings up to $176,100 in 2026. Beyond that cap, you only pay the 2.9% Medicare portion. However, if your income exceeds $200,000 (single) or $250,000 (married filing jointly), an additional 0.9% Medicare surcharge kicks in.
A Real-World Comparison
Consider a freelance web developer earning $100,000 net versus a W-2 employee earning $100,000 salary. The employee has roughly $7,650 withheld for FICA, and their employer pays another $7,650. The freelancer pays approximately $14,130 in SE tax — about $6,480 more out of pocket. After factoring in the half-SE deduction's income tax savings, the actual gap narrows to about $4,500-5,500 depending on tax bracket, but it's still substantial.

How to Manage the Extra Tax Burden
First, make sure you're charging enough. Use our Freelance Hourly Rate Calculator to factor SE tax into your pricing. Second, maximize your business deductions — every dollar you deduct from your Schedule C reduces both your income tax and your SE tax. Read our guide on 10 tax deductions every freelancer should know. Third, set aside money for quarterly payments so you're not hit with a massive bill in April. Finally, consider a retirement account like a SEP IRA or Solo 401(k) — contributions reduce your taxable income while building your future.
The Silver Lining
Yes, freelancers pay more in payroll-type taxes. But they also have far more control over their deductions. Home office, mileage, equipment, insurance, retirement contributions, professional development — W-2 employees lost most of these deductions after 2017's tax reform. Freelancers kept them all. The key is tracking every legitimate expense and using every deduction available to you.
