Self-employment tax in California
California is graduated to 13.3%; most self-employed filers land in the 8-9.3% brackets.
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 California contractor needs is higher than in the nine no-income-tax states.
Local note: An $800 annual LLC franchise tax applies if you operate as an LLC.
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.
