IMPORTANT: 2023 Arizona State Tax Changes

Arizona's Individual Income Tax Withholding Form (Arizona Form A-4) has been updated to reflect Arizona's lower individual income tax rates. The new Form A-4 has seven new withholding rates while retaining the exempt withholding option and the option for additional Arizona tax withholdings.

The University will adjust all employee's tax withholding percentage to "2%". This change will be reflected on the Friday, January 27, 2023, paycheck. This will be the default rate for employees who do not fill out the new Form A-4 by Friday, January 20, 2023, at 5:00 p.m.

To update your Arizona Form A-4, employees can go to UAccess Employee > UA Employee Main Homepage > Payroll & Compensation > State Forms > A-4 Tax Information.
