Self-Employment Tax: Complete 2026 Guide
If you're a freelancer, independent contractor, gig worker, or small business owner, you owe self-employment (SE) tax on your net earnings. This guide covers the 2026 rates, how the math works, deductions that reduce your bill, and how to avoid penalties with quarterly estimated payments.
What Is Self-Employment Tax?
Self-employment tax covers Social Security and Medicare — the same FICA taxes that W-2 employees split with their employer. When you're self-employed, you pay both halves:
| Component | Employee Share | Employer Share | Self-Employed Total |
|---|---|---|---|
| Social Security | 6.2% | 6.2% | 12.4% |
| Medicare | 1.45% | 1.45% | 2.9% |
| Total FICA / SE Tax | 7.65% | 7.65% | 15.3% |
The Social Security portion (12.4%) applies to net earnings up to $176,100 in 2026. The Medicare portion (2.9%) has no cap — it applies to all net earnings. If your net self-employment income exceeds $200,000 ($250,000 married filing jointly), you also pay an additional 0.9% Medicare surtax.
How to Calculate Self-Employment Tax
The calculation has a few steps. Here's a worked example for a freelancer earning $80,000 net:
Example: $80,000 Net Self-Employment Income
Step 1: Multiply net earnings by 92.35%: $80,000 × 0.9235 = $73,880
(The IRS lets you exclude 7.65% to simulate the employer-share deduction)
Step 2: Calculate Social Security: $73,880 × 12.4% = $9,161
Step 3: Calculate Medicare: $73,880 × 2.9% = $2,143
Step 4: Total SE tax: $9,161 + $2,143 = $11,304
Effective SE tax rate: $11,304 ÷ $80,000 = 14.13%

SE Tax at Common Income Levels
| Net Earnings | SE Tax | Effective Rate | Quarterly Payment |
|---|---|---|---|
| $30,000 | $4,238 | 14.13% | $1,060 |
| $50,000 | $7,065 | 14.13% | $1,766 |
| $75,000 | $10,597 | 14.13% | $2,649 |
| $100,000 | $14,130 | 14.13% | $3,533 |
| $150,000 | $21,195 | 14.13% | $5,299 |
| $200,000 | $26,532 | 13.27% | $6,633 |
Deductions That Lower Your Self-Employment Tax
1. The 50% SE Tax Deduction
You can deduct the employer-equivalent portion of your SE tax (50%) when calculating your adjusted gross income. This doesn't reduce your SE tax directly — it reduces your income tax. On $80,000 of net SE income with $11,304 in SE tax, you'd deduct $5,652 from your taxable income.
2. Business Expense Deductions
Every legitimate business expense reduces your net earnings, which directly reduces both your SE tax and income tax. Common deductions include home office, equipment, software, mileage (70 cents/mile in 2026), and professional development.
3. SEP IRA or Solo 401(k)
Contributing to a retirement plan reduces your taxable income (though not your SE tax base). A SEP IRA allows up to 25% of net self-employment income (max $70,000 in 2026). A Solo 401(k) allows $23,500 employee deferral plus 25% employer contribution. See our 2026 contribution limits guide.
4. Health Insurance Deduction
Self-employed individuals can deduct 100% of health insurance premiums for themselves and their family. This is an above-the-line deduction, meaning it reduces your adjusted gross income directly.
Quarterly Estimated Tax Payments
The IRS expects you to pay taxes as you earn throughout the year. If you expect to owe $1,000 or more in tax, you should make quarterly estimated payments to avoid penalties.
| Quarter | Income Period | Due Date |
|---|---|---|
| Q1 | January 1 – March 31 | April 15, 2026 |
| Q2 | April 1 – May 31 | June 15, 2026 |
| Q3 | June 1 – August 31 | September 15, 2026 |
| Q4 | September 1 – December 31 | January 15, 2027 |
Avoid Penalties
To avoid underpayment penalties, pay at least 90% of your current year's tax liability or 100% of last year's (110% if your AGI was over $150,000). The simplest approach: pay 100% of last year's total tax in four equal installments.
Self-Employment Tax vs. Income Tax
Self-employed people owe two separate taxes, and it's important to understand both:
| Self-Employment Tax | Federal Income Tax | |
|---|---|---|
| Rate | 15.3% (flat) | 10%–37% (progressive) |
| Applies to | 92.35% of net SE earnings | AGI minus deductions |
| Standard deduction | No | Yes ($15,000 single) |
| SS wage cap | $176,100 | N/A |
A freelancer earning $100K net pays roughly $14,130 in SE tax plus $10,000–$13,000 in federal income tax, depending on deductions. That's $24,000–$27,000 total before state taxes.
Frequently Asked Questions
Who has to pay self-employment tax?
Anyone with net self-employment earnings of $400 or more per year. This includes freelancers, independent contractors, sole proprietors, partners in a partnership, and gig workers (Uber, DoorDash, Etsy sellers, etc.). You report SE income on Schedule SE.
Can I reduce self-employment tax by forming an S-Corp?
Yes, potentially. As an S-Corp, you pay yourself a "reasonable salary" (subject to FICA) and take remaining profits as distributions (not subject to SE tax). If you earn $150K and pay yourself a $90K salary, you save SE tax on the $60K in distributions. Consult a CPA, as the IRS scrutinizes unreasonably low salaries.
Do I pay self-employment tax on rental income?
Generally no. Rental income from real estate is considered passive income and is not subject to SE tax. However, if you're in the business of renting properties (like a real estate dealer), it may be classified as SE income.
What's the difference between 1099 and W-2 for taxes?
W-2 employees have FICA taxes split with their employer (7.65% each). 1099 contractors pay the full 15.3% SE tax themselves, but can deduct business expenses and the employer-equivalent SE tax. On the same gross income, a 1099 worker typically pays $3,000–$8,000 more in total tax than a W-2 employee, depending on deductions.
