    What This Statute Says

    A.R.S. § 42-11053 lets the Department of Revenue inspect property, review business records, and require taxpayers to file detailed valuation statements. Refusing to cooperate can lead to a default valuation set by the department.

    1. Enter on and examine any property in this state to determine its full cash value. If the owner or possessor of property refuses entrance to the director or the director's agent, the director may estimate the valuation of the property.

    A.R.S. § 42-11053

    The audit power applies most often to centrally valued property, utilities, mines, pipelines, and to large commercial parcels. For owner-occupied homes and smaller estates, the assessor's mass appraisal handles valuation without an individual audit.

    If the department issues a request for records and the taxpayer refuses, the consequence is a default valuation. The taxpayer then has to appeal to undo the default, which is harder than appealing a regular valuation.

    When This Statute Comes Into Play

    This statute typically becomes relevant in three situations. A property owner is reviewing an annual tax bill. An estate is being administered and the personal representative has to address ongoing property tax obligations. Or a charitable or nonprofit organization is claiming or maintaining an exemption. The statute is part of a larger framework in chapter 11 of title 42 and operates alongside the related sections cross-linked below.

    What This Means for Arizona Families

    Most families never think about Arizona property tax statutes until they are sitting at a closing table on an inherited home, reviewing an unexpected tax bill, or trying to claim an exemption for a surviving spouse. When that moment arrives, the rules in chapter 11 of title 42 are the framework you are working inside.

    If you are holding real property in a revocable living trust, the trust structure does not by itself remove the property from the tax rolls. The exemption has to come from a specific statute. Our FAQ on what to do with property you inherit in Arizona covers the immediate practical questions, and our FAQ on probate timelines covers how a contested or stalled administration can affect tax filings and exemptions.

    If you are administering an estate, the personal representative has a duty to keep property taxes current, to claim available exemptions where appropriate, and to maintain documentation in case the assessor reviews a claim later. Calendar the February exemption filing window each year for any property where a widow, widower, or disability exemption applies. Once the deadline passes, the saving for that year is usually lost.

    42-11053. Investigating property valuations A. The department shall investigate property valuations and any matters relating to property taxes and shall require the production of any private or public record relating to those valuations or property taxes. B. The director or the director's agent may: 1. Enter on and examine any property in this state to determine its full cash value. If the owner or possessor of property refuses entrance to the director or the director's agent, the director may estimate the valuation of the property. 2. Require any officer whose duties relate to assessing or collecting taxes to report to the director at the time and in the manner that the director prescribes.
