Self-employment tax in New Jersey
New Jersey is graduated to 10.75%; most self-employed filers land in the 5.53-6.37% brackets.
New Jersey uses graduated brackets topping out near 6.37%, layered on top of federal income tax and the 15.3% self-employment tax. The federal half never changes: 15.3% on 92.35% of net profit, then income tax on profit less half that SE tax, the standard deduction and up to 20% qualified business income.
The failure mode is cash, not arithmetic. 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 New Jersey and federal bills are funded before you see the money.

Are there local taxes on self-employment income in New Jersey?
New Jersey does not add a broad local income tax on self-employment earnings, so state and federal are the two layers to plan for.
Can an S-corp lower self-employment tax in New Jersey?
