Register a new company
Visit the AZ Taxes website (note: it may require using Internet Explorer or Firefox) and select Register for an AZTaxes Account.
Follow the prompts in the registration and complete the form. Both tax agencies process your application separately, and each agency will notify you once the processing is complete. For unemployment tax you will be liable once you have paid $1500 wages in a calendar quarter or had one employee for part of a day in 20 different weeks in a calendar year.
The online registration process can take 2-3 weeks online. Please keep this time frame in mind when planning your first Arizona payroll. Alternatively, your request will be processed same-day if you register in person at a local Arizona Department of Revenue office.
Your unemployment tax rate and JTT rate will be sent to you annually and appear on the Determination of Unemployment Tax Rate letter you receive from the DES.
Unemployment Tax Rate: For new employers, the rate is 2.00%. Verify your rate by calling the DES at (602) 771-6602.
If you have any questions, you can also call the AZ DOR at (602) 255-3381.
