Does Arizona have a state income tax?

Yes. Arizona uses a flat 2.5% income tax — one of the lowest flat-rate states in the country. The flat structure makes Arizona's tax math simpler than the federal income tax calculation — but freelancers still owe the full 15.3% self-employment tax on top, plus federal income tax.

How self-employment tax works for Arizona freelancers

The federal self-employment (SE) tax is identical in every state, including Arizona. It's 15.3% (12.4% Social Security + 2.9% Medicare) applied to 92.35% of your Schedule C net profit. The Social Security portion caps at the 2026 wage base of $184,500; the Medicare portion has no cap. Half of the SE tax is deductible above-the-line on your federal return.
