Arizona updates individual income tax withholding form

01/05/23

Author: ADP Admin/Tuesday, January 3, 2023/Categories: Compliance Corner

Arizona Form A-4 has been modified because the previous Form A-4 is no longer representative of new lower income tax rates.

The Details: 

In the 2021 legislative session, Arizona enacted Senate Bill 1828 (SB 1828), which significantly reduced individual tax rates starting with the 2022 tax year.

The Arizona Department of Revenue (ADOR) is requiring all employees to complete and submit the revised Form A-4 beginning with the 2023 tax year.  If an employee does not submit an updated state income tax withholding election, employers must withhold Arizona income tax at the default rate of two percent.

Frequently Asked Questions provided by the ADOR state:

 

·       Employers have until January 31, 2023, to make the revised Form A-4 available to employees.

·       Employers may implement the change immediately upon an employee’s submission of the revised Form A-4 and do not need to wait until January of 2023.

·       Employers should retain a copy of the employee’s revised Form A-4. The form should NOT be sent to the ADOR.

·       If the employer should utilize a substitute electronic Form A-4 rather than paper, the electronic form can be updated to reflect the new withholding percentage.

 
Next Steps:

Your payroll system is scheduled to have the revised Form A-4 available beginning December 16, 2022.  Employees using employee self-service to complete the revised Form A-4 will be presented with the 2023 withholding options and the employee’s 2023 election will take effect on the next 2023 payroll, depending on the effective date of the change.  Any remaining pay dates in 2022 will have withholding at a rate of 2.7 percent (the default rate for 2022), depending on the effective date of the change.  If your employees want to use their existing 2022 withholding election for all remaining 2022 pay dates, they should be advised not to complete the revised Form A-4 until after a date that would make the change effective after their last pay date in 2022.
