South Dakota — no individual income tax (2025)
South Dakota levies no individual income tax for 2025, so a full-year resident owes it nothing. The zero below is a computed figure with an authority behind it, not an empty page.
This is a hypothetical South Dakota return, so the official layout is not offered for it. A page that looked exactly like the printed form would be mistaken for one.

What this South Dakota return is not telling you
Every line above computed. Nothing is blank for want of an entry, and no line hit a rule this engine has not built yet.
