How South Dakota taxes your paycheck in 2026
South Dakota is one of nine states that levy no state income tax on wages. Your paycheck is reduced only by federal income tax and FICA. On top of that, every South Dakota worker pays federal income tax plus 6.2% Social Security (on the first $184,500 of 2026 wages) and 1.45% Medicare with no cap. This calculator applies all of it at once, so the take-home figure is the real one.
What South Dakota charges instead
South Dakota has no personal income tax and no corporate income tax. Revenue comes primarily from a 4.2% state sales tax, with municipalities adding up to about 2%, plus tourism and contractor excise taxes.
South Dakota's sales tax applies to many services that other states exempt, which broadens the base and keeps the rate comparatively low.
Crossing into Minnesota or Iowa
Neither Minnesota nor Iowa has a reciprocity agreement covering South Dakota residents in the way some neighbouring state pairs do. If you live in Sioux Falls but work at a Minnesota site, Minnesota tax generally applies to the income earned there — a meaningful gap given Minnesota's rates start at 5.35%.
What living in South Dakota saves you
State income tax a single filer would owe on a $75,000 salary elsewhere — money a South Dakota worker keeps outright:
| If you lived in | State income tax on $75k | Your South Dakota saving |
|---|---|---|
| Minnesota | $3,577 | $3,577 |
| Iowa | $2,238 | $2,238 |
| Nebraska | $2,533 | $2,533 |
| South Dakota | $0 | — |
Income tax only. Sales and property taxes claw back part of this in most no-income-tax states.
Federal taxes on top
Every South Dakota worker also pays federal income tax plus 6.2% Social Security and 1.45% Medicare. Those rules are identical in all 50 states — see the main paycheck calculator for how FICA, the wage base, pre-tax deductions and FICA-exempt occupations work.
