Taxation and Finance Arizona 4 Minutes Read ยท published February 08, 2026 Flag of Arizona

In Tucson, Arizona property owners receive annual valuations that form the basis for property tax bills. This guide explains how assessments are prepared, whom to contact at the county level, what review and appeal options typically exist, and practical steps to check or challenge an assessed value. Use the listed official resources to confirm deadlines and to submit appeals promptly. For most residential and commercial parcels in Tucson the Pima County Assessor administers valuations and provides notices to taxpayers.[1]

Overview of the Assessment Process

Assessments begin with the Pima County Assessor determining a parcel's full cash value using sales, cost, and income approaches where applicable. Notices are mailed or posted online and show the assessed value and exemption status. If you disagree with the assessed value, start with an informal review, then pursue formal appeal channels described below.

  • Review your annual valuation notice as soon as you receive it and check for incorrect property details.
  • Gather recent comparable sales, photos, and records of improvements or damages that affect value.
  • Contact the Pima County Assessor for an informal review or clarification of the appraisal methodology.[1]
  • If unresolved, file a formal appeal with the County Board of Equalization, then further appeals follow state tax procedures.
Start the review process as soon as you receive the valuation notice to preserve appeal rights.
