Self-Employment Tax Calculator (U.S.)





If you’re self-employed in the United States—whether you’re a freelancer, independent contractor, or small business owner—you are responsible for paying your own taxes, including self-employment tax. Our Self-Employment Tax Calculator helps you quickly estimate how much you owe, so you can plan ahead and set aside enough money.

Unlike traditional employees, self-employed individuals must pay both the employer and employee portions of Social Security and Medicare taxes, which together form the self-employment tax. This rate is 15.3% of your net earnings.

Our calculator also estimates your federal income tax based on a simplified 10% rate. For most self-employed individuals earning under $60,000 per year, this gives a helpful ballpark figure.

This tool is ideal for:

  • Freelancers and gig workers
  • 1099 contractors
  • Online business owners
  • Etsy sellers, designers, writers, marketers, consultants
  • Anyone receiving untaxed income from clients

If you receive payments without tax already withheld, you’re responsible for calculating and paying your own tax liabilities. This calculator makes that easier.

Self-employment tax covers two key components:

  • Social Security tax (12.4%)
  • Medicare tax (2.9%)

Together, these form the 15.3% tax rate applied to your net income—your total income minus eligible business expenses.

For example:

  • Income: $50,000
  • Expenses: $10,000
  • Net income: $40,000
  • Estimated self-employment tax: $6,120

You may also owe federal income tax, depending on your total income, deductions, and filing status.

Many self-employed people are surprised at tax time. If you don’t set aside money throughout the year, you may face a large bill and possible penalties from the IRS.

Using this calculator:

  • Helps you plan your quarterly estimated payments
  • Prevents tax debt
  • Gives you peace of mind and control over your finances

We recommend setting aside 25%–30% of your net income to cover taxes unless your accountant suggests otherwise.

To use the calculator, simply:

  1. Enter your total income (gross revenue).
  2. Enter your expenses (deductible business costs).
  3. Click Calculate.

The tool will display:

  • Your net income
  • Estimated self-employment tax (15.3%)
  • Estimated federal income tax (flat 10% for simplicity)
  • Total estimated tax to set aside

Note: This is a simplified estimation. For personalized tax advice, please consult a licensed tax professional.

✅ Is this calculator accurate for my tax filing?

It provides a basic estimate using standard rates. If your income is higher, you may owe more due to progressive federal tax brackets or additional Medicare tax.

✅ Can I use this for quarterly estimated taxes?

Yes. Divide your annual estimated tax by four to estimate quarterly payments. You can adjust each quarter based on your actual income.

✅ What if I live in a state with income tax?

This calculator does not include state income tax. We recommend checking your state’s rates and adding that amount to your estimate.

As a self-employed professional, staying on top of your taxes is just as important as growing your business. Use this calculator regularly—especially if your income changes month to month—to make sure you’re prepared and protected.
