    What This Statute Says

    A.R.S. § 42-11154 governs how a nonprofit organization proves its nonprofit status when claiming a property tax exemption. The organization must submit documentation of its IRS determination, articles of incorporation, and qualifying use of the property.

    1. Nonprofit organization status may be established by a letter of determination issued in the organization's name by the United States internal revenue service recognizing the organization's tax-exempt status under section 501 of the internal revenue code, except that:

    A.R.S. § 42-11154

    This statute is the audit backbone for every nonprofit property tax exemption. The organization must demonstrate that it is genuinely a nonprofit, that its activities match the qualifying category, and that the specific property is being used in that mission.

    For estate-planning families who control a charitable foundation that owns Arizona real property, the documentation under this statute should be maintained on file in case the assessor reviews the exemption.

    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.

    42-11154. Establishing nonprofit status For the purposes of article 3 of this chapter: 1. Nonprofit organization status may be established by a letter of determination issued in the organization's name by the United States internal revenue service recognizing the organization's tax-exempt status under section 501 of the internal revenue code, except that: (a) A church, synagogue, temple, mosque or similar organization is not required to provide a letter of determination to establish its status as a tax-exempt organization. (b) If the nonprofit organization is included in a group exemption letter by the internal revenue service, the group exemption letter satisfies the requirement under this paragraph provided the central organization that received the group exemption from the internal revenue service provides a letter certifying that the nonprofit organization is included in the group exemption. (c) An organization that meets the requirements of section 501(c)(3) of the internal revenue code but that is exempt from the notification requirements pursuant to section 508(c) of the internal revenue code shall not be required to provide a letter of determination from the internal revenue service. 2. The requirement that property is not used or held for profit may be met by a letter of determination described in paragraph 1 of this section and issued in the name of the organization holding title to the property and for each organization using the property.
