Self-Employment Tax Explained: What Freelancers Must Know
Self-Employment Tax Explained: What Freelancers Must Know
If you’re new to freelancing, the self-employment tax might come as an unwelcome surprise. Unlike traditional employees who split Social Security and Medicare taxes with their employers, freelancers pay both portions—totaling 15.3% of net earnings. This guide explains everything you need to know about self-employment tax and how to minimize its impact.
What Is Self-Employment Tax?
Self-employment tax is the combination of Social Security and Medicare taxes that self-employed individuals must pay. When you work for an employer, they withhold these taxes from your paycheck and pay half (7.65%) while you pay the other half. As a freelancer, you’re responsible for both halves.
Quick Answer
Self-employment tax is 15.3% of your net earnings (12.4% for Social Security + 2.9% for Medicare). You must pay this tax if your net earnings from self-employment exceed $400 in a year.
Key Takeaways
- Self-employment tax rate is 15.3% (Social Security 12.4% + Medicare 2.9%)
- Applies to net earnings over $400
- Social Security portion capped at $168,600 income (2026)
- Medicare portion has no income limit
- You can deduct 50% of self-employment tax as a business expense
- Quarterly estimated payments required to avoid penalties
Breaking Down the 15.3%
Social Security Tax (12.4%)
- Rate: 12.4% of net earnings
- Income Cap: $168,600 in 2026
- Maximum Tax: $20,906.40 (if income exceeds cap)
- Income above $168,600 is not subject to the Social Security portion
Medicare Tax (2.9%)
- Rate: 2.9% of net earnings
- No Income Cap: Applies to all net earnings
- Additional Medicare Tax: 0.9% on earnings over $200,000 (single) or $250,000 (married filing jointly)
How to Calculate Self-Employment Tax
The calculation is more complex than simply multiplying your income by 15.3%. Here’s the formula:
Step 1: Calculate Net Earnings
Net Earnings = Gross Income - Business Expenses
Step 2: Calculate Taxable Amount
Taxable Amount = Net Earnings × 92.35%
(The 7.65% reduction accounts for the employer portion deduction)
Step 3: Calculate Self-Employment Tax
- Social Security Portion: Taxable Amount × 12.4% (up to $168,600)
- Medicare Portion: Taxable Amount × 2.9%
- Total: Social Security + Medicare
Example Calculation
Let’s say your freelance business earns $80,000 in gross income with $15,000 in business expenses:
Step 1: Net Earnings = $80,000 - $15,000 = $65,000
Step 2: Taxable Amount = $65,000 × 92.35% = $60,027.50
Step 3:
- Social Security: $60,027.50 × 12.4% = $7,443.41
- Medicare: $60,027.50 × 2.9% = $1,740.80
- Total Self-Employment Tax: $9,184.21
Income Tax: Plus you’ll owe regular income tax on the net earnings
The Deduction Benefit
Here’s some good news: You can deduct half of your self-employment tax as a business expense on Schedule C. This reduces your adjusted gross income (AGI).
Using our example above:
- Self-employment tax: $9,184.21
- Deduction: $4,592.10
This deduction doesn’t reduce your self-employment tax itself, but it does lower your income tax.
When Do You Pay Self-Employment Tax?
Unlike employees who have taxes withheld from each paycheck, freelancers must make quarterly estimated tax payments that include both income tax and self-employment tax.
2026 Quarterly Due Dates
- Q1 (Jan-Mar): April 15, 2026
- Q2 (Apr-May): June 15, 2026
- Q3 (Jun-Aug): September 15, 2026
- Q4 (Sep-Dec): January 15, 2027
How Much to Pay Each Quarter
To avoid underpayment penalties, pay at least:
- 90% of your current year’s tax liability, OR
- 100% of last year’s tax liability (110% if AGI over $150,000)
Use Form 1040-ES to calculate and pay quarterly taxes.
Who Must Pay Self-Employment Tax?
You must pay self-employment tax if:
- Your net earnings from self-employment are $400 or more
- You work as an independent contractor, freelancer, or gig worker
- You’re a member of a partnership that carries on a trade or business
- You’re otherwise in business for yourself (including part-time businesses)
Exceptions
Some income is not subject to self-employment tax:
- Rental income from real estate
- Dividends and interest
- Gains or losses from property sales
- Limited partner income (with exceptions)
Strategies to Reduce Self-Employment Tax
1. Maximize Business Deductions
Every dollar of business expense reduces your net earnings, which reduces your self-employment tax. Common deductions:
- Home office
- Equipment and supplies
- Software subscriptions
- Professional services
- Travel expenses
- Marketing and advertising
2. Contribute to Retirement Accounts
Retirement contributions don’t reduce self-employment tax directly, but they reduce your income tax. Consider:
- SEP IRA (up to 25% of net earnings, max $69,000)
- Solo 401k (up to $69,000, or $76,500 if 50+)
3. Hire Family Members
Employing your children (under 18) in your business can shift income to them at a lower tax rate, and their wages aren’t subject to Social Security and Medicare taxes if your business is a sole proprietorship.
4. Use an S-Corporation
If your net earnings are substantial (typically $60,000+), converting to an S-corporation may reduce self-employment tax. You pay yourself a “reasonable salary” (subject to payroll taxes) and take the rest as distributions (not subject to self-employment tax).
Example:
- Sole Proprietorship: $100,000 net earnings × 15.3% = $15,300 SE tax
- S-Corp: $60,000 salary (payroll taxes) + $40,000 distributions (no SE tax) = ~$9,180 payroll taxes
- Savings: ~$6,120
Caveat: S-corps have additional compliance costs and requirements. Consult a tax professional.
5. Take the Home Office Deduction
If you work from home, the home office deduction reduces your net earnings, thereby reducing self-employment tax.
Common Mistakes to Avoid
1. Not Budgeting for Self-Employment Tax
Many new freelancers are surprised by the 15.3% additional tax. Set aside 25-30% of your income for taxes (income tax + self-employment tax).
2. Missing Quarterly Payments
Waiting until April to pay all your taxes results in underpayment penalties and a massive tax bill.
3. Not Taking All Deductions
Every missed deduction means paying more self-employment tax than necessary.
4. Ignoring State Taxes
Most states also have self-employment or income taxes. Don’t forget to budget for state obligations.
5. Not Keeping Records
Poor record-keeping can lead to missed deductions and problems if you’re audited.
Self-Employment Tax vs. Income Tax
It’s important to understand that self-employment tax and income tax are separate:
| Type | Rate | What It Funds |
|---|---|---|
| Self-Employment Tax | 15.3% | Social Security & Medicare |
| Income Tax | 10-37% | Federal government operations |
You pay both taxes on your net earnings. The income tax rate depends on your tax bracket.
Reporting Self-Employment Tax
Report self-employment tax on:
- Schedule C (Form 1040): Report income and expenses to calculate net earnings
- Schedule SE (Form 1040): Calculate self-employment tax
- Form 1040: Report the total tax liability
The Bottom Line
Self-employment tax is a significant expense for freelancers, but understanding how it works helps you plan and minimize its impact. Key strategies include:
- Maximizing business deductions
- Making quarterly estimated payments
- Considering retirement contributions
- Evaluating S-corporation status for high earners
- Keeping excellent records

Frequently Asked Questions
Do I pay self-employment tax if I also have a W-2 job?
Yes, if your net earnings from self-employment exceed $400. However, your W-2 wages count toward the Social Security wage base ($168,600), potentially reducing the Social Security portion of your self-employment tax.
Can I avoid self-employment tax?
Generally, no—not if you’re genuinely self-employed. However, you can reduce it through legitimate deductions and, in some cases, S-corporation status.
What if I earn less than $400?
If your net earnings are under $400, you don’t owe self-employment tax, but you may still owe income tax on the earnings.
Do I pay self-employment tax on 1099 income?
Yes, income reported on Form 1099-NEC (non-employee compensation) is subject to self-employment tax if it exceeds $400 after expenses.
Is self-employment tax the same as estimated tax?
No. Self-employment tax is the 15.3% Social Security and Medicare tax. Estimated tax is the quarterly payment system used to pay both income tax and self-employment tax throughout the year.
Can I deduct self-employment tax?
You can deduct 50% of your self-employment tax as an adjustment to income on Form 1040. This reduces your adjusted gross income (AGI) but doesn’t reduce the self-employment tax itself.
