South Dakota tax FAQ

How much state income tax will I pay in South Dakota?

South Dakota has no state income tax on wages, so you'll owe $0 in state income tax. You may still owe other state-level taxes (sales, property).

What's the difference between federal and South Dakota state tax?

Federal income tax is collected by the IRS using nationwide brackets (10%–37%). South Dakota state income tax (where applicable) is separate and uses its own brackets and deductions. Both apply to most South Dakota residents.

Are these the 2025 or 2026 tax brackets?

The calculator uses tax year 2025 federal brackets — the figures you'll use to file in early 2026. The IRS adjusts brackets annually for inflation; we update when 2026 figures are released.

Should I take the standard deduction or itemize?

Take whichever is larger. The 2025 standard deduction (as boosted by the One Big Beautiful Bill Act, July 2025) is $15,750 (single), $31,500 (married filing jointly), or $23,625 (head of household). Itemize if your mortgage interest, state and local taxes (capped at $10,000), and charitable donations exceed that amount.
