Income reported on a 1099 form is taxed in two layers: self-employment tax at 15.3% and federal income tax at rates from 10% to 37%. Most independent contractors end up with a combined effective 1099 tax rate somewhere between 15% and 30%, depending on total income, filing status, and the deductions they can claim. Nothing is withheld by the payer, so the full amount is yours to calculate and send in.
What Gets Taxed Is Net Profit, Not the 1099 Amount
The gross figure on your 1099 is not the number the IRS taxes. You report that income on Schedule C and subtract ordinary business expenses to arrive at net profit.1Internal Revenue Service. About Schedule C (Form 1040), Profit or Loss from Business (Sole Proprietorship) That net profit is the base for both taxes below, so every legitimate expense you deduct cuts both bills at once.
Common Schedule C deductions include the business use of your home, vehicle expenses at the 2026 IRS standard mileage rate of 70 cents per mile, equipment and software, professional development, business insurance, advertising, subcontractor payments, office supplies, and professional subscriptions.2Internal Revenue Service.

The 15.3% Self-Employment Tax
Self-employment tax funds Social Security and Medicare. A W-2 employee splits this with an employer; you cover both halves, which comes to 12.4% for Social Security and 2.9% for Medicare, for a total of 15.3%.3Office of the Law Revision Counsel. 26 USC 1401 – Rate of Tax
The 15.3% is not applied to your full net profit. The IRS runs it on 92.35% of net earnings, which brings the effective rate down to about 14.13% of your Schedule C bottom line.4Internal Revenue Service. Topic No. 554, Self-Employment Tax The reduction roughly matches the tax break W-2 workers get by not being taxed on the employer’s share of FICA.
The 12.4% Social Security portion only applies up to an annual wage base. For 2026, that cap is $184,500.5Social Security Administration. Contribution and Benefit Base Self-employment earnings above that amount escape Social Security tax. The 2.9% Medicare portion has no cap.
High earners owe an additional 0.9% Medicare surtax on combined earnings above $200,000 for single filers or $250,000 for married couples filing jointly, bringing the Medicare rate above that threshold to 3.8%.6Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes)
One partial offset: you can deduct half of your self-employment tax when calculating adjusted gross income on Form 1040.4Internal Revenue Service. Topic No. 554, Self-Employment Tax The deduction does not shrink the self-employment tax itself, but it does lower the income subject to the second layer.
Federal Income Tax Brackets for 2026
After the half-of-SE-tax deduction, your net profit joins the rest of your household income and runs through the progressive federal brackets. For 2026, single filers face these rates:7Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026
- 10% on income up to $12,400
- 12% from $12,401 to $50,400
- 22% from $50,401 to $105,700
- 24% from $105,701 to $201,775
- 32% from $201,776 to $256,225
- 35% from $256,226 to $640,600
- 37% above $640,600
Married couples filing jointly get roughly double those bracket widths: the 12% bracket extends to $100,800, the 22% bracket to $211,400, and so on.7Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 These are marginal rates. Only the income that falls within each bracket is taxed at that rate. A single filer with $60,000 in taxable income pays 22% on the portion above $50,400, not on the entire $60,000.
Your actual income tax rate depends on your filing status, whether you itemize or take the standard deduction, other household income, and any credits you qualify for. A single freelancer with $50,000 of net Schedule C profit ends up with an effective income tax rate well below the top bracket that any part of that income touches.
The Qualified Business Income Deduction
The single biggest lever on the income tax side is the Section 199A qualified business income deduction, which lets you subtract up to 20% of net qualified business income before the brackets are applied.8Office of the Law Revision Counsel. 26 US Code 199A – Qualified Business Income On $80,000 of Schedule C profit, that is a $16,000 reduction to taxable income. The deduction was originally scheduled to expire after 2025 and was made permanent by the One Big Beautiful Bill Act signed into law in July 2025.
QBI reduces taxable income only. It does not touch adjusted gross income or self-employment tax. For a freelancer in the 22% or 24% bracket, though, it effectively shaves about a fifth off the income tax rate on business earnings.
The full 20% is available without restriction as long as total taxable income stays below roughly $201,750 for single filers or $403,500 for joint filers in 2026. Above those thresholds, limits phase in, and the rules split by profession. The IRS treats certain fields as specified service trades or businesses, including health care, law, accounting, consulting, financial services, performing arts, and athletics.9eCFR. 26 CFR 1.199A-5 – Specified Service Trades or Businesses and the Trade or Business of Performing Services as an Employee Freelancers in those fields lose the QBI deduction entirely once income clears the top of the phase-in. A self-employed tradesperson at the same income can still qualify, based on wages paid and the value of business assets.
Other Deductions That Move the Rate
Retirement Contributions
A SEP IRA lets you contribute up to 25% of net self-employment earnings, capped at $72,000 for 2026. A Solo 401(k) allows up to $24,500 as the employee portion ($32,500 if you are 50 or older) plus up to 25% of net earnings as the employer portion, with a combined ceiling of $72,000 under 50. These contributions reduce income subject to federal income tax. They do not reduce self-employment tax.
Self-Employed Health Insurance
If you pay for your own health insurance and are not eligible for coverage through a spouse’s employer, premiums for medical, dental, and vision coverage for you, your spouse, and your dependents are deductible on Form 1040. The deduction cannot exceed your net self-employment income, and it does not reduce self-employment tax.
Paying the Tax Through Quarterly Estimates
Because no one is withholding tax from your 1099 payments, you pay as you go using Form 1040-ES. The requirement applies if you expect to owe $1,000 or more in federal tax for the year after subtracting withholding and refundable credits.10Internal Revenue Service. Form 1040-ES – Estimated Tax for Individuals Each quarterly payment should cover both estimated self-employment tax and estimated income tax.
For 2026, the four deadlines are April 15, June 15, September 15, and January 15, 2027. Underpaying triggers a penalty tied to the federal short-term rate plus three points, currently 7% and compounded daily for the first quarter of 2026.11Internal Revenue Service. Rev. Rul. 2025-22
Two safe harbors let you avoid the penalty. Pay at least 90% of your current year’s actual tax across the four installments, or pay 100% of last year’s total tax (110% if your prior year AGI was above $150,000).12Internal Revenue Service. Underpayment of Estimated Tax by Individuals Penalty The prior-year safe harbor is useful when income swings, because the target does not depend on what the current year turns out to be.
State Tax Sits on Top of All of This
The rates above are federal only. Most states impose their own income tax on self-employment earnings, with rates that range from under 2% to over 13%. A handful of states levy no income tax at all. State rules on deductions, estimated payments, and filing deadlines vary, so the federal effective rate on your 1099 income is a floor in most places, not the whole bill.
