South Dakota is one of nine states with no personal income tax. Residents keep every dollar of earnings from state-level taxation, though the state generates revenue through other means such as sales taxes, property taxes, and in some cases severance taxes on natural resources. The zero-income-tax policy makes South Dakota particularly attractive for high earners, remote workers, and retirees seeking to maximize their after-tax income.
