Understanding Self-Employment Tax in 2026
Self-employment tax is the federal tax paid by individuals who work for themselves to fund Social Security and Medicare benefits. Unlike W-2 employees, who split these taxes with their employers, self-employed individuals are responsible for both the employee and employer portions. For 2026, the combined self-employment tax rate remains 15.3%, consisting of 12.4% for Social Security and 2.9% for Medicare.
The 92.35% Rule
The tax applies to "net earnings from self-employment," calculated by multiplying net profit by 92.35%. This accounts for the employer-equivalent deduction. If you earn $100,000 in net profit, only $92,350 is subject to SE tax.
Understanding self-employment tax is critical because it often represents the largest tax burden for freelancers and independent contractors — frequently exceeding federal income tax. A freelancer in the 12% income tax bracket may still face an effective 14.1% self-employment tax rate, making total federal tax liability over 26% before state taxes.

How Self-Employment Tax Is Calculated: Step by Step
Determine Net Business Profit
Start with your gross business income from all sources. Subtract ordinary and necessary business expenses reported on Schedule C.
Multiply by 92.35%
Multiply your net profit by 0.9235 to arrive at 'net earnings from self-employment'. This accounts for the employer-equivalent deduction.
Apply Social Security Wage Base
For 2026, the 12.4% Social Security tax applies only to the first $183,000 of your combined wages and net SE earnings.
Calculate Medicare Tax
The 2.9% Medicare tax applies to ALL net SE earnings with no wage base limit. A 0.9% surtax applies if income exceeds certain thresholds.
Claim the Deduction
Multiply your total SE tax by 50% and deduct this amount on Schedule 1 (Form 1040), Line 15. This reduces your Adjusted Gross Income (AGI).

SE Tax vs. W-2 Employee FICA
| Aspect | W-2 Employee | Self-Employed |
|---|---|---|
| Social Security | 6.2% Employee / 6.2% Employer | 12.4% Total |
| Medicare | 1.45% Employee / 1.45% Employer | 2.9% Total |
| Effective Rate ($80k) | ~7.65% (Withheld) | ~14.1% (Paid Directly) |
Plan Your Quarterlies
Because taxes aren't withheld, the IRS requires quarterly estimated tax payments using Form 1040-ES. For 2026, the due dates are: April 15, June 15, September 15, and January 15, 2027.
Failure to pay at least 90% of your current year or 100% of your prior year tax can result in underpayment penalties.
6 Strategies to Reduce SE Tax
Elect S-Corp Status
Pay a reasonable salary and take distributions SE-tax free. This can save thousands on profits above $40k-$60k.
Maximize Deductions
Every dollar deducted (Home office, equipment, etc.) reduces both income and SE tax.
Hire Family Members
Legitimate wages to minor children in a sole prop are often FICA-free and reduce your net profit.
Retirement Contributions
Solo 401(k) or SEP-IRA contributions reduce taxable income, lowering your overall tax bracket.
Health Insurance
Self-employed health premiums are deductible above-the-line, reducing your Adjusted Gross Income.
Income Splitting
Form partnerships or joint ventures to split income and stay below high-earner tax thresholds.
SE Tax by Business Entity Type
Sole Proprietor
All net profit subject to SE tax. Simplest setup, highest exposure.
Single-Member LLC
Taxed like a sole prop. Liability protection, but no tax savings.
S Corporation
Only salary is subject to FICA. Profits are SE-tax free. High savings.
Partnership
General partners pay SE tax on their distributive share of income.
C Corporation
Owner-employees pay FICA only on wages. No SE tax on retained profits.
Frequently Asked Questions

You can deduct 50% of your total self-employment tax as an above-the-line deduction on Form 1040 Schedule 1.
Do LLC members pay self-employment tax?
Yes, general LLC members typically pay SE tax on their distributive share unless the LLC elects to be taxed as an S-Corp.
What income is NOT subject to SE tax?
Rental income, interest, dividends, and capital gains are generally exempt unless you are a real estate professional.
