Self-employment tax in Arizona
Arizona uses a 2.5% flat tax, one of the lowest in any state that taxes income.
Arizona applies a flat 2.5% individual income tax 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 Arizona and federal bills are funded before you see the money.
Frequently asked questions
How much self-employment tax do you pay in Arizona?
Self-employment tax is federal: 15.3% on 92.35% of net profit, the same in Arizona as everywhere else. Arizona applies a flat 2.5% individual income tax on top of federal income tax and the 15.3% self-employment tax.
What is the total tax rate for self-employed people in Arizona?
Most Arizona self-employed filers land between 27% and 38% of net profit once federal income tax, the 15.3% SE tax and the 2.5% state rate are combined.
Do I file quarterly estimates in Arizona?
Yes — federal estimates when you expect to owe $1,000 or more, plus Arizona state estimates on roughly the same April, June, September and January schedule.
Are there local taxes on self-employment income in Arizona?
Arizona 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 Arizona?
It can, once profit is high enough. Payroll tax then applies only to a reasonable salary rather than all profit. Arizona state income tax still applies to the full amount, so the savings are federal.
