✦ What Employers Need to Know

Key facts about your state payroll taxes.

A quick overview of what's involved before you run your first payroll.

Arizona has a flat income tax rate of 2.5% as of 2023 — one of the lowest flat rates in the country, significantly reduced from the prior graduated rate structure.
Arizona new employers pay a UI rate of 2.0% on the first $8,000 of each employee's wages. Experienced employer rates range from 0.03% to 8.36%.
Arizona has no state SDI program and no broad local payroll taxes. Two registrations required: Arizona Department of Revenue (withholding) and Arizona Department of Economic Security (UI).
Arizona employers register for both withholding and UI through the AZTaxes portal. The flat 2.5% income tax rate makes withholding calculations simpler than most states.
