How South Dakota taxes income
South Dakota is one of a small group of states with no state income tax on wages, which can mean noticeably higher take-home pay compared to a state with a progressive tax.
South Dakota generally does not tax common forms of retirement income like pensions and 401(k)/IRA withdrawals, which can make it more attractive for retirees.
Frequently asked questions
What's the difference between marginal and effective tax rate?+

Does this include deductions and credits?+
This calculator applies published bracket rates to your taxable income but doesn't model state-specific standard deductions, exemptions, or credits, which can meaningfully lower your actual bill.
