South Dakota Income Tax in 2026

South Dakota does not levy a state income tax. Wages, salaries, business income and most investment income are not taxed at the state level — only federal income tax, payroll tax (Social Security + Medicare), and any local taxes apply.

This makes South Dakota attractive for high earners, though states often make up the difference through higher sales tax, property tax, or excise taxes. Compare total tax burden, not just income tax, when choosing where to live.
