Arizona Withholding Tax

Print Friendly, PDF & Email

Information for Employers

An employer must withhold Arizona income tax from employees whose compensation is for services performed within Arizona.   Arizona state income tax withholding is a percentage of the employee’s gross taxable wages.

Gross taxable wages refers to the amount that meets the federal definition of wages contained in U.S. Code § 3401.  Generally, this is the amount included in box 1 of the employee’s federal Form W-2.   Amounts considered to be wages for federal tax purposes are considered to be wages for Arizona income tax purposes.  Amounts included in wages and subject to mandatory federal withholding are subject to mandatory Arizona withholding. Amounts excluded from wages and from mandatory federal withholding are excluded from mandatory Arizona withholding.

Refer to: Employer Withholding Filing Obligations for additional information on withholding Arizona income tax.

 

Employee Withholding Determination

The department will follow the determination of the IRS regarding a worker’s employment status as an employee or as an independent contractor.  Refer to Arizona Withholding Tax Ruling (WTR) 16-4 to determine if a worker is an employee or an independent contractor for Arizona withholding tax purposes.

To compute the amount of tax to withhold from compensation paid to employees for services performed in Arizona, an employee must complete Arizona Form A-4, Arizona Withholding Percentage Election, within the first five days of employment. If the employee does not complete the form, the employer must withhold Arizona income tax at the rate of 2.7% until the employee elects a different withholding rate.  Refer to the Employer’s Instructions for Arizona Form A-4 for further information.

To change the amount of Arizona income tax withheld, an employee must complete Arizona Form A-4 and submit to his or her employer to choose a different withholding percentage option.
