South Dakota is one of nine states that levies no income tax on wages and salaries. The state funds its government primarily through sales taxes, property taxes, and other revenues. This can result in significant savings for high-income earners compared to states with high marginal rates.
On the South Dakota median household income of $59,533, the combined federal and state income tax comes to approximately $8,150, leaving $51,383 in after-tax income.
