Notice of Claim

The Notice of Claim is a defined statutory process that allows for the homeowner/taxpayer to notify the Assessor's office when they discover a factual error, as defined in A.R.S § 42-16251, or legal classification of their property. A Notice of Claim along with supporting documentation may be filled with the Assessor between January 1st to December 31st for the current tax year and the 3 preceding tax years. Approved changes will be applied towards future years and do not need to be added to the claim form. Per statute, the Assessor's office may either consent to or dispute the claimed error within 60 days after receiving the Notice of Claim.

For re-classification of your primary residence, please submit a completed Notice of Claim form with an attached copy of your Driver’s license or Voters Registration card.

  • 3.2 - Primary Residence of a qualified family member
