If you've already sent a tax notice to Avalara, we'll send you POA form that has Avalara's information pre-filled.

To submit a POA:

  1. Download the Arizona Form 285 General Disclosure/Representation Authorization form.
  2. Complete the form. Pay close attention to these sections:
    • Section 1 - Taxpayer information:
      • Taxpayer name: Enter the business name. This should match the business name on your TPT license.
      • Present address: Enter your current primary business address.
      • AZ Transaction Privilege Tax No.: Enter the license number from your TPT license.
    • Section 2 - Appointee information: This is the name and information of the Avalara employee that will handle your tax notices. 
    • Section 3 - Tax matters: Select Transaction Privilege and Use Tax, then enter a date range in the Year(s) or Period(s) section.
      Make sure the date range includes the filing period for which you received the tax notice.
    • Section 4 - Additional authorization: Select an option in this section. Options 4g and 4h generally provide Avalara with enough access to help resolve tax notices on your behalf. If you select 4h, enter a description of the access you're authorizing.
    • Section 5 - Power of Attorney: Select the checkbox, then enter any limitations to the power of attorney.
    • Section 8 - Signature of or for taxpayer: Enter your signature, printed name, title, and the current date.
