The federal taxes every self-employed person pays
No matter which state you're in, self-employment income carries federal self-employment tax of about 15.3% (12.4% Social Security up to the annual wage base, plus 2.9% Medicare), on top of federal income tax. You may also qualify for the 20% qualified business income (QBI) deduction, and you can deduct half of your self-employment tax. The calculator above includes all of this along with Colorado's state tax.
Because you don't have an employer withholding taxes for you, you're generally expected to pay quarterly estimated taxes. A common rule of thumb is to set aside 25–30% of your net profit, but your exact number depends on your income and deductions, use the estimate above as your starting point.
