Revised Withholding Form A-4 Effective January 31

January 18, 2023

Phoenix, AZ—The Arizona Department of Revenue (ADOR) has updated the Employee’s Arizona Withholding Election form (Arizona Form A-4) to reflect Arizona's seven lower individual income tax rates. The new Form A-4 also retained both the zero withholding rate option and the line for additional Arizona withholding.

Every Arizona employer must provide the new tax rate options to Arizona employees by January 31 in the method of their choosing, either electronically through an online portal, fillable form, or paper form.

If an employee fails to fill out the new Form A-4, the default rate will be 2.0%. The form should not be submitted to ADOR; it should be kept by the employer and the employee with their tax records.

Common questions and answers can be found here.

Taxpayers can follow ADOR on social media to receive notices regarding filing requirements, tax rate changes, law changes, and reminders.
