Self-employment tax in Kansas
Kansas uses a two-bracket structure topping out at 5.58%.
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 Kansas contractor needs is higher than in the nine no-income-tax states.
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.
