How Income Tax Works in South Dakota (2026)
South Dakota is one of nine U.S. states with no state income tax on wages. Your income tax bill consists of federal income tax only — on a $75,000 salary, that's about $7,670 for a single filer using the standard deduction. Combined with FICA taxes (Social Security and Medicare), total withholding comes to about $13,408, leaving you with $61,593 take-home pay.
The absence of state income tax gives South Dakota residents an immediate advantage over the 4.8% average state tax rate paid in states that do levy income tax. On a $100,000 salary, that's roughly $4,770 per year in savings. However, South Dakota may compensate through higher sales taxes, property taxes, or other fees — your total tax burden depends on spending and homeownership, not just income.

Methodology & sources
Federal tax uses 2026 IRS brackets and standard deductions (Revenue Procedure 2025-32). State tax rates reflect 2026 law from the Tax Foundation and state revenue departments; graduated-state figures are estimated effective rates. FICA uses the 2026 Social Security wage base of $184,500 (6.2%) plus Medicare (1.45%). Local city or county taxes (e.g. NYC, Portland) are not included. Estimates for planning only, not tax advice.
