Eligibility
- Activities: Any self-employed trade or business reported on Schedule C
- Requires tax residency
- Federal tax alone. This is the complete picture only in the nine states that levy no personal income tax on earned income — Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington and Wyoming. Washington now taxes individuals with adjusted gross income of $1,000,000 or more (Washington DOR), so its exemption is no longer unconditional. Everywhere else, add state (and sometimes city) tax on top: see us-sole-proprietor-california and us-sole-proprietor-new-york-city for the two extremes covered by this dataset. Modelled for a single filer taking the standard deduction with no dependents and no other income.

Important context
Federal rules only, for a single filer with no dependents, no other income and no itemized deductions, taking the standard deduction. Not modelled, all of which would lower the figures: the self-employed health-insurance deduction, deductible retirement contributions (SEP-IRA or solo 401(k)), the home-office deduction, and any tax credits. The §199A(i) minimum deduction of $400 introduced by the One Big Beautiful Bill Act only matters at taxable incomes under $2,000 and is not modelled either. The engine applies the §199A deduction at 20% of taxable income, which is the binding limit whenever business profit is the taxpayer's only income; taxpayers with substantial other income can instead be limited by 20% of qualified business income. An S-corporation election — paying yourself a salary and taking the rest as distributions exempt from self-employment tax — is the standard way US freelancers cut this burden further, but the IRS sets no percentage for what counts as reasonable compensation, so there is no official rule to model and no scheme for it here.
