What this calculator covers
- Self-employment tax: 12.4% Social Security up to the $184,500 wage base and 2.9% Medicare, on 92.35% of net profit.
- Federal income tax using the 2026 brackets and standard deduction, after the deductible half of SE tax and the 20% qualified business income deduction.
- The child tax credit and credit for other dependents, including the refundable portion, and the earned income credit for filers with children.
- State income tax for the states listed above, using each state's own deductions, exemptions and brackets.
Not covered: itemized deductions, self-employed health insurance and retirement contributions, S-corporation elections, the childless earned income credit (it depends on age), and city or county income taxes. Each of those lowers or changes the result; the figure here is a conservative estimate.
