Assumptions: simplified federal brackets, simplified SE tax, simplified standard deduction and optional simplified QBI estimate. Actual taxes vary by deductions, credits, additional income, and state rules.
How Are 1099 Self-Employed Taxes Calculated in the USA?
If you’re self-employed (1099 contractor, freelancer, or business owner), your estimated taxes typically include self-employment tax (Social Security + Medicare) plus federal income tax and state income tax (depending on where you live).
Unlike W-2 employees, self-employed individuals generally pay both the employee and employer portion of payroll taxes. Your taxable base is usually your net profit (gross income minus eligible business expenses). Actual tax outcomes can vary based on deductions, credits, additional income, and state-specific rules.
What’s included in this calculation?
- Estimated self-employment tax (Social Security + Medicare)
- Estimated federal income tax (progressive brackets)
- Estimated state income tax (varies by state; some states have no income tax)
- Business expense impact (reduces net profit)
- Optional simplified standard deduction and QBI estimate (where applicable)

Why Self-Employed Taxes Feel Higher
Self-employed workers often see higher tax estimates because they pay the full self-employment tax component (covering both employer and employee payroll contributions). While you may deduct eligible expenses and potentially qualify for deductions like the standard deduction and (in some cases) a QBI deduction, the overall effective tax rate can still feel higher than a similar W-2 salary.
Frequently Asked Questions
How much should I set aside for taxes as a freelancer?
Many self-employed workers set aside a percentage of net profit to cover federal income tax, state tax (if applicable), and self-employment tax. The right amount depends on your income level, deductions, filing status, and state. Use the calculator above to estimate your total annual tax and quarterly payments.
Do I pay taxes on gross income or net profit?
In most cases, self-employed taxes are based on net profit (gross income minus eligible business expenses). However, your final taxable income may also be affected by deductions and credits.
What is self-employment tax?
Self-employment tax typically covers Social Security and Medicare contributions for self-employed individuals. Unlike W-2 employees (who split this with an employer), self-employed workers generally pay both portions.
Do I need to pay quarterly estimated taxes?
Many freelancers and contractors pay taxes quarterly to avoid penalties, especially if they don’t have taxes withheld through an employer. This tool estimates your quarterly payments by dividing the annual estimate into four.
Which states have no state income tax?
Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming do not tax personal income at the state level.
