Open Freelance Tax Calculator →Freelancers in South Dakota benefit from zero state income tax, but still owe the full 15.3% self-employment tax (Social Security + Medicare) plus federal income tax on their net earnings. The SE tax alone can feel like a significant burden since you pay both the employer and employee portions of FICA. However, the absence of state tax means your effective rate is materially lower than freelancers in taxed states. Use the calculator to estimate quarterly obligations and plan for the half-of-SE-tax deduction that reduces your adjusted gross income.
South Dakota is one of nine states with no personal income tax. Residents keep every dollar of earnings from state-level taxation, though the state generates revenue through other means such as sales taxes, property taxes, and in some cases severance taxes on natural resources. The zero-income-tax policy makes South Dakota particularly attractive for high earners, remote workers, and retirees seeking to maximize their after-tax income.
The table below shows what you actually keep at five salary levels in South Dakota, accounting for federal tax, FICA, and zero state income tax.
