In 2021, Governor Doug Ducey signed Senate Bill 1828, which increased the maximum taxable wages from $7,000 to $8,000 for Unemployment Insurance (UI) compensation purposes, effective calendar year 2023. This legislation also made other changes to the UI program, including additional program integrity requirements. 

The Arizona Legislature substantially reduced Arizona's individual income tax rates for the 2022 tax year. The previous Form A-4 withholding rates are no longer representative of the new lower income tax rates. Employers should select the 2.0% default on behalf of the employee.

Employees will still have the option of selecting a higher Arizona withholding rate than their wages might dictate and there is still a line to add an additional amount of Arizona withholding.
