Quick Answer
Self-employment tax is 15.3% of your net freelance income, covering Social Security (12.4%) and Medicare (2.9%) contributions. Unlike W-2 employees who split these costs with employers, freelancers pay the full amount. On $30,000 of net freelance income, you'd owe $4,239 in self-employment tax.

Self-employment tax is 15.3% of your net freelance income
Self-employment tax covers your Social Security and Medicare contributions as a freelancer. According to IRS Publication 334, the rate is 15.3% (12.4% for Social Security + 2.9% for Medicare) on your net earnings from self-employment.
When you're an employee, you only pay 7.65% of these taxes because your employer pays the other half. As a freelancer, you're both the employee AND the employer, so you pay the full 15.3%.
How self-employment tax is calculated
Self-employment tax is calculated on 92.35% of your net self-employment income (not your gross income). The 7.65% reduction accounts for the employer portion of the tax, which is deductible.
Example: $25,000 in freelance income
Let's break down the self-employment tax on $25,000 of net freelance income:
Income thresholds that matter
Social Security tax cap: In 2026, you only pay the 12.4% Social Security portion on income up to $176,100. Above that, you only pay the 2.9% Medicare tax.
Additional Medicare tax: If your total income exceeds $200,000 (single) or $250,000 (married filing jointly), you pay an additional 0.9% Medicare tax on the excess.
Minimum threshold: You must pay self-employment tax if your net earnings are $400 or more.
Self-employment tax vs. income tax
These are two separate taxes:
Both apply to the same income, so your effective tax rate on freelance income is typically 25-40% depending on your bracket.
The self-employment tax deduction
Here's the good news: you can deduct half of your self-employment tax as a business expense on your Form 1040. Using our example above, you'd deduct $1,767 ($3,533 ÷ 2), which saves you about $389 in income taxes if you're in the 22% bracket.
How to pay self-employment tax
What you should do
1. Calculate your burden: Use our quarterly estimator to see how much you'll owe
2. Set aside money: Save about 15-20% of each payment just for self-employment tax
3. Track net income: Remember, it's calculated on profit (income minus expenses), not gross income
4. Consider the deduction: Factor in the 50% deduction when planning your taxes
Key takeaway: Self-employment tax adds 15.3% to your tax bill on net freelance income, but you can deduct half of it as a business expense, reducing the effective rate to about 14%.

Key Takeaway: Self-employment tax is 15.3% of net freelance income, but you can deduct half of it, making the effective rate about 14%.

For people who have a regular job and want to understand how self-employment tax affects their total tax picture
Self-employment tax applies only to your freelance income
When you have both W-2 and 1099 income, self-employment tax only applies to your freelance earnings. Your regular job already handles Social Security and Medicare taxes through payroll withholding.
The Social Security wage base affects both incomes
Here's where it gets tricky: the $176,100 Social Security wage base applies to your COMBINED W-2 and self-employment income. If your W-2 job already puts you near or over this limit, you might pay little to no Social Security tax on your freelance income.
Example: High W-2 earner with side hustle
Say you earn $150,000 from your W-2 job and $20,000 from freelancing:
Double Social Security credit
The good news about paying self-employment tax is that it counts toward your Social Security benefits, just like W-2 earnings. Higher lifetime earnings mean higher Social Security payments in retirement.
Managing cash flow
Unlike your W-2 job where taxes are automatically withheld, you need to set aside money for self-employment tax from each freelance payment. A good rule of thumb for side hustlers is to save 20-25% of freelance income for all taxes (income tax + self-employment tax).
Key takeaway: Side hustlers pay self-employment tax only on freelance income, and high W-2 earners may pay less Social Security tax due to the wage base cap.
Key Takeaway: Side hustlers pay self-employment tax only on freelance income, and high W-2 earners may pay less Social Security tax due to the wage base cap.

For people who freelance as their primary income and need to understand the full impact of self-employment tax
Self-employment tax is your biggest ongoing expense
As a full-time freelancer, self-employment tax will likely be one of your largest business expenses. On $60,000 of net income, you're looking at $8,478 in self-employment tax alone - that's $706 per month you need to set aside.
The additional Medicare tax threshold
Once your freelance income exceeds $200,000, you'll pay an additional 0.9% Medicare tax on the excess. This brings your total self-employment tax rate to 16.2% on high income. Unlike the regular Medicare tax, there's no employer equivalent to deduct for this additional tax.
Strategies to reduce self-employment tax
Business expense optimization: Every dollar of legitimate business expenses reduces both income tax and self-employment tax. Common missed deductions include:
Retirement contributions: Contributing to a SEP-IRA or Solo 401(k) reduces your net self-employment income, lowering self-employment tax. On $50,000 of income, a $10,000 SEP-IRA contribution saves you about $1,413 in self-employment tax.
S-Corporation election: For consistently high earners ($60,000+), electing S-Corp status can save thousands in self-employment tax. You'd pay yourself a reasonable salary (subject to payroll taxes) and take additional profit as distributions (not subject to self-employment tax).
Quarterly payment strategy
Self-employment tax makes up a large portion of your quarterly payments. Use the safe harbor rule: pay 100% of last year's total tax (110% if your prior year AGI exceeded $150,000) to avoid penalties, even if you owe more when you file.
Building Social Security credits
Full-time freelancers need 40 quarters (10 years) of Social Security credits to qualify for benefits. In 2026, you earn one credit for each $1,730 of covered earnings, up to four credits per year. Self-employment tax ensures your freelance income counts toward these credits.
Key takeaway: Full-time freelancers should budget 15-16% of net income for self-employment tax and explore strategies like retirement contributions or S-Corp election to reduce this burden.
