What Taxes 1099 Contractors Actually Pay

As a 1099 contractor, you are treated as self‑employed, which means you pay both self‑employment tax and regular federal income tax on your net profit. Understanding this dual tax structure is essential for proper financial planning throughout the year.

  • Self‑employment tax covers Social Security and Medicare contributions that employers normally split with W‑2 employees.
  • Federal income tax applies on top of that, based on your taxable income and filing status, using the same bracket system as traditional employees.
  • Many contractors also owe state and local income taxes, depending on where they live, though we focus on federal obligations here.

For 2025 (filed in 2026), the combined self‑employment tax rate is 15.3% on your net self‑employment earnings: 12.4% Social Security up to the annual wage base of $168,600 and 2.9% Medicare on all earnings, plus an extra 0.9% Medicare surtax for high earners above specific thresholds.

Self‑Employment Tax Rates (1099 Contractors)

Self‑Employment Tax Rates (1099 Contractors)

Here are the key self‑employment tax rules that apply to 1099 contractors for the 2025 tax year, based on current IRS guidance.

  • Who pays self‑employment tax: Anyone with at least $400 in net self‑employment earnings must file and pay.​
  • Total self‑employment tax rate:
    • 15.3% on net earnings up to $168,600 (combining 12.4% Social Security plus 2.9% Medicare).
    • 2.9% Medicare only on earnings above $168,600, since Social Security tax caps at that wage base.
    • Extra 0.9% Additional Medicare Tax on income over $200,000 (single) or $250,000 (married filing jointly).
  • Only 92.35% of your net self‑employment income is subject to self‑employment tax, meaning you multiply net profit by 0.9235 first.​
  • You can deduct half of your self‑employment tax as an adjustment to income on your tax return, which lowers your adjusted gross income.

Example from current guidance: if your net self‑employment income is $50,000, then 92.35% of that (50,000×0.923550,000 × 0.923550,000×0.9235) is about $46,175, and 15.3% of that equals roughly $7,060 in self‑employment tax.​

Federal Income Tax For 1099 Contractors

On top of self‑employment tax, your net profit after deductions is also subject to federal income tax using the same progressive brackets W‑2 employees use. This means your income is taxed in layers, with each portion taxed at its corresponding rate.

For 2025, typical numbers look like this for common filing statuses:

  • Standard deduction: $15,750 for single filers, $31,500 for married filing jointly, and $23,625 for head of household.​
  • Federal tax brackets step up in layers; you pay 10% on the first slice of taxable income, 12% on the next slice, then 22%, 24%, 32%, 35%, and 37% on higher portions.

One example walkthrough shows that on $50,000 of taxable income, the effective federal income tax (average rate across all income) can be around 12%, even though the marginal bracket might be 22%. That illustrates why your “top bracket” is not the same as the overall percentage you pay on everything you earn.​

Step‑By‑Step: How To Estimate Your 1099 Tax Bill

You can think of your 1099 taxes in three clear stages: calculating net income, determining self‑employment tax, and computing federal income tax.

  1. Calculate net self‑employment income
    • Start with your total 1099 and other business income for the year.​
    • Subtract all allowable business expenses such as software subscriptions, home office portion, supplies, mileage, professional services, and more to arrive at your net profit (the Schedule C number).
  2. Estimate self‑employment tax
    • Multiply your net profit by 92.35% to get the self‑employment tax base.​
    • Apply 15.3% up to the Social Security wage cap ($168,600), then 2.9% Medicare on all income, plus the 0.9% Additional Medicare Tax if you exceed the high‑earner threshold.
  3. Estimate federal income tax
    • Start with your total income including self‑employment earnings and any other taxable income.
    • Subtract above‑the‑line deductions, most importantly half of your self‑employment tax.
    • Subtract either the standard deduction for your filing status or your itemized deductions if higher.​
    • Apply the 2026 tax brackets for your filing status to the resulting taxable income, calculating tax layer by layer.
  4. Combine them
    • Total federal tax bill ≈ self‑employment tax + federal income tax.

FAQs

Q: What percentage should a 1099 contractor save for taxes?
A: Most contractors aim for 20%–30% of net income to cover self‑employment and federal income tax combined, though the exact number depends on your income level, available deductions, and state tax obligations.

Q: Do 1099 contractors pay more tax than W‑2 employees?
A: They often feel like they do because they pay both the employee and employer portions of Social Security and Medicare through self‑employment tax, but strategic deductions can narrow or offset that difference.

Q: When do I have to pay 1099 taxes during the year?
A: If you expect to owe at least $1,000 in tax for the year after withholding and credits, the IRS generally requires quarterly estimated payments instead of waiting until the April deadline.

Q: Do I still pay self‑employment tax if I earn only a small amount?
A: Yes, if your net self‑employment earnings reach $400 or more in a year, self‑employment tax typically applies and must be reported.
