How does South Dakota make up for having no income tax?
States without a wage tax rely more on sales, property, excise or resource taxes, so your total state and local tax bill depends on where you live and what you spend. For take-home pay, though, South Dakota workers keep more of each paycheck than workers with the same salary in income-tax states — see the South Dakota paycheck calculator.
How is the federal part calculated?
Federal income tax uses the same 2026 brackets in every state: 10% up to $12,400 of taxable income for single filers, rising to 37% above $640,600, after a $16,100 standard deduction. See the full table on the federal income tax calculator.
