Arizona self-employment tax questions
What is the self-employment tax rate in Arizona?
The self-employment tax rate is 15.3% on net self-employment earnings up to $184,500 for 2026, then 2.9% above that. It is a federal tax, so the rate in Arizona is the same as every other state. Arizona separately taxes that income at 2.5% flat.
Do freelancers in Arizona pay self-employment tax?
Yes. Every freelancer and independent contractor in the US, Arizona included, owes self-employment tax once net self-employment earnings reach $400 for the year. You can deduct half of the SE tax from gross income on your federal return.
Does Arizona have its own self-employment tax?
No. Arizona does not levy a separate self-employment tax. It taxes self-employment income as ordinary income at 2.5% flat, which is a different tax from the federal 15.3% SE tax. Arizona freelancers pay the federal SE tax (15.3%) plus a flat 2.5% Arizona state income tax — one of the lowest state rates in the US.
How much of self-employment tax is deductible in Arizona?
Half of your self-employment tax is deductible from gross income on your federal return, which lowers federal income tax but not the SE tax itself. The deduction is federal; Arizona treatment follows its own rules for calculating state taxable income.
