Self-Employment Tax 2026: Rates, Limits & How to Estimate Yours

Self-Employment Tax 2026 at a Glance

When you work for yourself, you pay both the employee and employer share of payroll taxes. For tax year 2026 the combined self-employment (SE) tax rate stays at 15.3% of your net self-employment earnings: 12.4% for Social Security plus 2.9% for Medicare. It is calculated on 92.35% of your net profit—the IRS lets you exclude the 7.65% "employer half" from the base before applying the tax.

Two 2026 limits matter. Social Security tax stops once your net self-employment earnings reach $184,500 in 2026, while Medicare tax has no cap. And if your earnings exceed $200,000 ($250,000 for married filing jointly, $125,000 for married filing separately), an additional 0.9% Medicare tax applies to the excess.

Then Comes Federal Income Tax

Self-employment tax is not your only federal obligation. You also pay income tax on your profit, but only after two important deductions. First, you can deduct half of your SE tax (the "employer" share) before income tax is computed. Second, you subtract the 2026 standard deduction: $16,100 for single filers, $32,200 for married filing jointly, and $24,150 for heads of household.

The 2026 federal income tax brackets for a single filer are: 10% on income up to $12,400; 12% from $12,400 to $50,400; 22% from $50,400 to $105,700; 24% from $105,700 to $201,775; 32% from $201,775 to $256,225; 35% from $256,225 to $640,600; and 37% above $640,600. Married filing jointly thresholds are roughly double. Only the income inside each band is taxed at that band's rate.

A Worked Example for 2026

Say you are single and your freelance business clears a $68,000 net profit for 2026. Self-employment tax is 15.3% of $62,798 (92.35% of $68,000), or about $9,608—well under the Social Security cap. Half of that, about $4,804, is deductible. Your taxable income is $68,000 minus $4,804 minus the $16,100 standard deduction, or about $47,096, which lands fully inside the 12% band after the first $12,400. Federal income tax comes to roughly $5,404.

Your total 2026 federal tax bill is therefore around $15,012, or about 22% of your profit. Run your own numbers through the Contractor Tax Estimator below—it models this exact sequence with the 2026 rates and shows your net income and effective rate.

What This Estimate Leaves Out

This is a federal, single-person approximation. It does not model the 20% qualified business income (QBI) deduction, tax credits, dependents, itemized deductions, or state and local taxes. The QBI deduction in particular can reduce taxable income for many freelancers, so your real bill may be lower. Treat the estimate as a planning figure, not a filing number, and confirm the details with tax software or a professional.

Pay It Quarterly, Not Once a Year

Because no employer withholds your tax, the IRS expects you to pay as you earn. US freelancers generally make four estimated tax payments each year, due around April 15, June 15, September 15 and January 15. For 2026 income, the next installments are September 15, 2026 and January 15, 2027. Paying on time matters: the underpayment penalty is avoidable if your timely payments cover 90% of your 2026 tax or 100% of your 2025 tax (110% for higher-income filers)—whichever is smaller.

Get an Instant 2026 Estimate

The quickest way to turn these rules into a number is to run your gross income and deductible expenses through the estimator. It applies the 2026 SE tax structure, the half-SE deduction, your standard deduction and the 2026 brackets automatically, and splits the result into SE tax, income tax, net income and your effective rate.
