What This Statute Says
A.R.S. § 42-11056 requires the Department of Revenue to maintain records of every property valuation and to be notified of changes. The notification rule keeps state and county records aligned and protects against drift between the rolls.
A. The department may maintain a complete and current record of all property that is subject to property tax and of property tax assessments in this state.
A.R.S. § 42-11056The statute is a record-keeping rule. Counties report valuation changes; the department keeps the master record. The result is a single statewide picture of the property tax base, broken out by county.
For estate planners, the chief practical use is data: historical valuations available through county and state records can support gift tax filings, step-up-in-basis calculations, and contested inventory valuations in probate.
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.
