Self-employment tax in South Dakota
South Dakota has no individual income tax.
Federal rules are the same everywhere: you pay 15.3% self-employment tax on 92.35% of net profit, then income tax on profit less half of that SE tax, the standard deduction and up to 20% qualified business income. What changes state to state is the layer on top — which is why the reserve percentage a South Dakota contractor needs is lower than in most of the country.
The failure mode isn't the arithmetic, it's cash. Money lands, it gets spent, and the quarterly due date becomes a crisis. Hate Ledger moves the reserve out of reach the day each deposit clears, so the bill is funded before you see it.
