South Dakota levies no individual income tax. There is no state rate schedule, no state standard deduction, no state withholding on your paycheck and no state return to file on wages. South Dakota raises its money from sales tax and levies no corporate income tax either, which is why so many financial companies are chartered there.
What no state income tax actually means
- Federal income tax still applies in full. A no-income-tax state changes one line on your payslip, not the biggest one — federal withholding, Social Security at 6.2% and Medicare at 1.45% all come out exactly as they would anywhere else.
- There is no South Dakota return to file on wages, and no state withholding line on your paycheck. That is real administrative relief, not just a rate of zero.
- You can still owe income tax to a different state. If you live in South Dakota but work across a state line, that state generally taxes the income you earn there — the neighbouring pages below are the ones to check.
- A zero income tax is not a zero tax burden. States without one raise the money somewhere else, usually sales tax, property tax or a resource levy, and those land differently on different households. South Dakota raises its money from sales tax and levies no corporate income tax either, which is why so many financial companies are chartered there.

Assumptions
- Ordinary-income rate schedules only; no credits, AMT, capital-gains rates, QBI deduction or the 2025–2028 senior deduction.
- Standard deduction (plus additional amounts for 65+/blind) or your itemized figure, whichever is larger; no dependent-filer limitation.
- Married filing separately uses half the joint federal thresholds, per the IRS schedule, and the state's single-filer schedule.
- State tax uses each state's published rate schedule, standard deduction and personal exemption for the tax year shown with the results; the source URL and year for the state you pick are printed above the results, along with the simplifications made for that state.
- State figures exclude county, municipal and city income taxes, itemized deductions, retirement and capital-gains exclusions, and credits that phase out. Unlisted states fall back to the flat rate you enter.
