You must use your Arizona unemployment tax account number to file a tax and wage report. If you have not been issued an Arizona unemployment tax account number visit aztaxes.gov to complete the registration process. For more information on how to apply see the Applying for an Unemployment Insurance Account Tax Number web page.
Once the registration process is completed you will receive a determination of unemployment insurance liability letter by mail. The determination letter includes your Arizona unemployment tax account number and tax rate that should be used when filing wage reports. Established employers may also find their Arizona unemployment tax account number and current tax rate on their annual tax rate notice.
Reports filed without an active account in our system will not be processed.
Unreported changes to your business may affect the processing of wage reports. For more information about the types of changes that should be reported see Report Changes to Your Business.
