The 2026 Rate at a Glance
When you work for an employer, you pay 7.65% in Social Security and Medicare tax and your employer pays a matching 7.65%. When you work for yourself, you pay both halves. That's self-employment (SE) tax:
| Part | Rate | Applies to (2026) |
|---|---|---|
| Social Security (OASDI) | 12.4% | Net SE earnings up to $184,500, minus any W-2 wages |
| Medicare (HI) | 2.9% | All net SE earnings |
| Total | 15.3% | |
| Additional Medicare Tax | 0.9% | Earnings above $200,000 single, $250,000 married filing jointly, $125,000 married filing separately |
The Social Security Administration set the 2026 maximum taxable earnings at $184,500, up from $176,100 in 2025. The 15.3% rate itself hasn't changed in decades.
Who Has to Pay
According to IRS Topic 554, you generally owe SE tax if your net earnings from self-employment are $400 or more. That includes sole proprietors, independent contractors, freelancers, gig workers and members of partnerships that carry on a trade or business. It applies on top of regular income tax, which is calculated separately.
How to Calculate It: Three Steps
Example: $60,000 net profit
- Start with net profit from Schedule C (income minus business expenses): $60,000.
- Multiply by 92.35%. $60,000 × 0.9235 = $55,410 of net earnings subject to SE tax. This adjustment mirrors the fact that employees aren't taxed on the employer's half of payroll taxes.
- Multiply by 15.3%. $55,410 × 0.153 = $8,477.73 of self-employment tax.
You then deduct half, $4,238.87, on Schedule 1 when figuring your income tax.
The effective SE tax rate on your profit is 15.3% × 92.35% ≈ 14.13%, below the headline rate.
Higher Earners: The Wage Base and the 0.9%
The 12.4% Social Security portion stops once net SE earnings reach $184,500 in 2026. Medicare's 2.9% never stops, and the 0.9% Additional Medicare Tax applies above the threshold for your filing status.
Example: $250,000 net profit, single
- Net SE earnings: $250,000 × 0.9235 = $230,875.
- Social Security: 12.4% × $184,500 (the cap) = $22,878.00.
- Medicare: 2.9% × $230,875 = $6,695.38.
- SE tax on Schedule SE: $29,573.38.
- Additional Medicare Tax on Form 8959: 0.9% × ($230,875 − $200,000) = $277.88.
The Additional Medicare Tax thresholds aren't indexed for inflation, so they're the same as in prior years. Half of SE tax is deductible; the Additional Medicare Tax is not part of that deduction.
If You Also Have a W-2 Job
Social Security wages from a job count toward the same $184,500 cap. If your W-2 Box 3 wages are $120,000, only $64,500 of SE earnings is subject to the 12.4% part. Schedule SE handles this. Medicare tax still applies to all of it, and the 0.9% threshold applies to combined wages and SE income.
The Deduction for Half of SE Tax
You can deduct the "employer-equivalent" half of your SE tax as an adjustment to income on Schedule 1. It reduces your adjusted gross income and therefore your income tax, but it doesn't reduce the SE tax itself. In the $60,000 example, the $4,238.87 deduction would save $509 of federal income tax in the 12% bracket or $932 in the 22% bracket.
Ways to Lower Self-Employment Tax Legally
- Claim every legitimate business expense. SE tax is based on net profit, so expenses like supplies, software, a qualifying home office and business mileage reduce it directly.
- Understand what doesn't help. Retirement contributions such as a SEP-IRA or solo 401(k), and the self-employed health insurance deduction, reduce income tax but not SE tax.
- Consider an S corporation election once profits are substantial. Owners take a reasonable salary subject to payroll tax and may take remaining profit as distributions that aren't. It adds payroll, filing and compliance costs, and the IRS requires the salary to be reasonable. Talk to a tax professional first.
Paying During the Year: Quarterly Estimates
No employer is withholding for you, so the IRS expects estimated payments using Form 1040-ES. For the 2026 tax year, the due dates are:
| Payment | Covers income earned | Due |
|---|---|---|
| 1 | Jan 1 – Mar 31 | April 15, 2026 |
| 2 | Apr 1 – May 31 | June 15, 2026 |
| 3 | Jun 1 – Aug 31 | September 15, 2026 |
| 4 | Sep 1 – Dec 31 | January 15, 2027 |
Generally, you avoid an underpayment penalty if you pay at least 90% of this year's tax or 100% of last year's (110% if your prior-year AGI was over $150,000). Many freelancers set aside 25% to 30% of each payment they receive to cover SE tax plus income tax; the right percentage depends on your bracket and state.
Common Mistakes
- Applying 15.3% to gross receipts instead of net profit.
- Forgetting the 92.35% step.
- Assuming retirement contributions reduce SE tax.
- Skipping quarterly payments and owing a lump sum plus penalties in April.

Where SE Tax Shows Up on Your Return
You report business income and expenses on Schedule C (or receive a Schedule K-1 from a partnership), calculate the tax on Schedule SE, and carry the result to Schedule 2 of Form 1040, where it is added to your income tax. The deduction for half of it goes on Schedule 1. If you owe the Additional Medicare Tax, Form 8959 calculates it. Tax software walks you through these forms, but knowing the flow helps you check the result.
SE tax also builds your Social Security record. The earnings you report count toward Social Security credits and future retirement and disability benefits, which is one reason underreporting income can cost you later as well as now.
Special Situations
- Several businesses: combine the net profit or loss from all of them on one Schedule SE. A loss from one can offset profit from another.
- Married couples: each spouse with self-employment income files a separate Schedule SE, since SE tax builds each person's own Social Security record.
- Low-income years: the IRS offers optional methods for farm and nonfarm income that can let you pay some SE tax to keep earning Social Security credits. See the Schedule SE instructions.
Frequently Asked Questions
What is the self-employment tax rate for 2026?
15.3%: 12.4% for Social Security on net earnings up to $184,500, plus 2.9% for Medicare on all net earnings. An extra 0.9% Additional Medicare Tax applies above $200,000 (single) or $250,000 (married filing jointly).
Do I pay self-employment tax on all of my profit?
No. You multiply net profit by 92.35% first, which mirrors the employer half of payroll tax that employees don't pay tax on. If the result is under $400, you generally owe no SE tax.
Is self-employment tax deductible?
Half of it is. You deduct 50% of your SE tax as an adjustment to income on Schedule 1. It lowers income tax, not the SE tax itself.
When are 2026 estimated tax payments due?
April 15, June 15 and September 15, 2026, and January 15, 2027. If a date falls on a weekend or legal holiday, the deadline moves to the next business day.
