Notices of Proposed Correction Mailed

---

MARICOPA COUNTY, Ariz, (May 24, 2024) – The Maricopa County Assessor's Office is sending out about 19 thousand Notices of Proposed Correction to address a court decision on Limited Property Value. This group is the final mailing for properties receiving an increase to that value as a result.

In Qasimyar et al. v. Maricopa County, the Tax Court ruled that a change from a Class 3 (primary residence) to a Class 4 (non-primary residence or rental), or vice versa, is technically a "change in use." As a result, the property's Limited Property Value (LPV) must be determined using a specific statutory calculation, which, in turn, affects the property's taxes. This ruling was ultimately upheld by the Arizona Court of Appeals in 2021.

In Arizona, a property's LPV (taxable value) is calculated using either Rule A or Rule B. Rule A is the “standard” calculation for LPV. Over 95 percent of all Maricopa County properties receive a Rule A, which increases the LPV by up to 5 percent each year but can never exceed the property's Full Cash Value (FCV).

Rule B is triggered when the prior year’s LPV cannot be used as a baseline because the property was omitted from the preceding year’s tax roll, was split, had an addition or deletion worth at least 15 percent of its FCV, or the use of the property changed. Rule B requires our office to recalculate the LPV using a countywide ratio. For example, for tax year 2022, the LPV ratio was 68 percent of the Full Cash Value for Class 3 parcels and 67 percent for Class 4 parcels.

Before the court decision, our office did not consider a change between Class 3 and Class 4, or vice versa, as a "change in use" because it remained a residential property. To implement the Court of Appeals' decision, our office had to recalculate the LPV of all properties that changed between Class 3 and Class 4 from tax year 2021 to tax year 2022 using Rule B regardless of whether the recalculation increased or decreased the property’s LPV - about 55,000 properties in total.

With this mailing, we have officially notified the roughly 20,000 property owners identified for an increase. We mailed around 35,000 Notices of Proposed Correction (NOPC) to the properties receiving a decreased LPV in October 2023.

The properties that receive an NOPC indicating an increase to the LPV will not see additional tax liability for any past or current tax years. However, these revised LPVs will serve as the foundation for the property's LPV in the future, which could impact the owner’s tax responsibility beginning in tax year 2025.

Following the court decision, in 2022, the Arizona Legislature passed SB1267, clarifying that a change between Class 3 and Class 4 does not qualify as a "change in use" and will not trigger a Rule B for tax years 2023 and later. Moving forward, Rule B will only be triggered if a property’s intended use changes, i.e., a residential property to a commercial property, it was left off the previous year’s tax roll, or there are significant changes to the property.

The Maricopa County Assessor's Office acknowledges that this court decision and subsequent NOPCs may raise questions and concerns. We are committed to providing transparency and support throughout this process to ensure property owners understand the changes and their options.

We are offering several virtual public education sessions where our subject matter experts will help property owners understand their revised value and any implications. They are as follows:

Property owners can RSVP for one of the sessions here.

If they cannot attend one of the four virtual sessions, they can schedule a 20-minute virtual appointment with a representative.

Property owners are encouraged to review their Notices of Proposed Correction promptly and respond within 30 days if they choose to contest the correction. If they do not respond after 30 days, we will correct the tax roll as proposed in the Notice.

For more information or assistance regarding the NOPCs, affected property owners are encouraged to contact the Maricopa County Assessor's Office at 602-506-3406 or email [email protected].

2025 Notices of Value Mailed

---

MARICOPA COUNTY, Ariz. (Feb. 23, 2024) - The Maricopa County Assessor's Office is dispatching Notices of Value to more than 1.7 million property owners this week, about 20 thousand more than last year. These Notices are for the 2025 tax year as property values in Arizona are set a full year ahead to allow for an extensive appeal process.

In a marked departure from the trend of the past decade, the median full cash value (FCV) on many property types has experienced a decrease. Manufactured housing saw the largest FCV decrease at -6.9%. Commercial properties were one of the only property types to see an increase in FCV with a gain of 2.3%. Meanwhile, the median limited property value (LPV), the value used for property tax purposes, continued to rise for all property types.

This shift in property values is attributed to the combined impact of Proposition 117 and the dynamic nature of the real estate market.

Since going into effect in 2015, voter-approved Proposition 117 has governed how LPV is calculated. If there are no significant changes to the property or how it is used, the LPV can increase by up to 5% but never surpass the FCV. 95% of all Maricopa County properties saw the standard LPV increase of 5%.

“We are committed to providing fair and equitable valuations that reflect the ever-changing dynamics of the real estate market,” said Maricopa County Assessor Eddie Cook. “The simultaneous decrease in median full cash value and increase in limited property value demonstrate the nuanced nature of our assessments."

Property owners have sixty days from the mailing date printed on their Notice to file an administrative appeal with the Assessor’s Office if they believe their property has been improperly valued or classified.

The Maricopa County Assessor's Office encourages property owners to review their Notices of Value and reach out with any questions or concerns. Online resources are available to assist property owners in understanding the valuation process, what information can be appealed, and the factors influencing their property values. They can also contact our office by calling 602.506.3406 or emailing [email protected].

Change to Organizational Exemptions Renewal Requirements

---

A revision to the organizational exemption renewal requirements will go into effect when the application period opens in January.

Senate Bill 1230, which was passed in 2023, states that a nonprofit organization with a 501(c) status is now eligible for a permanent exemption and no longer needs to renew annually. If approved, the exemption is valid until the property no longer qualifies for the exemption.

If there is a change to the property, the organization must notify the Assessor’s Office.

Contact the Organizational Exemptions team at [email protected] with any questions.

Notices of Proposed Correction mailed as result of court decision

---

MARICOPA COUNTY, Ariz. (Sept. 28, 2023) - The Maricopa County Assessor's Office is sending out about 79,000 Notices of Proposed Correction to address a court decision on limited property value. In Qasimyar et al. v. Maricopa County, the Tax Court ruled that a change from a Class 3 (primary residence) to a Class 4 (non-primary residence or rental), or vice versa, is technically a "change in use." As a result, the property's Limited Property Value (LPV) must be calculated using a specific statutory calculation, which, in turn, affects the property's taxes. This ruling was ultimately upheld by the Arizona Court of Appeals in 2021.

In Arizona, a property's LPV (taxable value) is calculated using either Rule A or Rule B. Rule A is the “standard” calculation for LPV. Over 95 percent of all Maricopa County properties receive a Rule A, which increases the LPV by up to 5 percent each year but can never surpass the property's Full Cash Value.

Rule B is triggered when the prior year’s LPV cannot be used as a baseline because, for example, the property was omitted from the preceding year’s tax roll, was split, had an addition or deletion to the property worth at least 15% of its full cash value, or the use of the property changed. Rule B requires our office to recalculate the LPV using a countywide ratio. For example, for tax year 2022, the LPV ratio is 67 percent of the Full Cash Value for Class 4 parcels and 68 percent for Class 3 parcels.

Before the court decision, our office did not consider a change between Class 3 and Class 4, or vice versa, as a "change in use" because it remained a residential property. These Notices of Proposed Correction implement the Court of Appeals' decision for the 2022 and 2023 tax years. Our records indicate that over 34,000 properties will have a decrease in LPV due to this recalculation, while over 44,000 properties will see an increase in LPV. This week, the Assessor’s Office is sending out Notices of Proposed Correction to the properties that will have a decreased LPV. These property owners will likely see a refund or adjustment to their property tax bill from the Maricopa County Treasurer's Office.

The properties that saw an increase to the LPV will not see additional tax liability for tax years 2022 or 2023 because of the Notices of Proposed Correction. However, these revised LPVs will serve as the foundation for the property's LPV in the future, which could impact the owner’s tax responsibility. The Assessor’s Office is still in the process of recalculating these increased LPVs and will send Notices of Proposed Correction to the affected property owners in the coming months.

Notably, in 2022, the Arizona Legislature passed SB1267, clarifying that a change between Class 3 and Class 4 does not qualify as a "change in use" and, therefore, will not trigger a Rule B for tax years 2024 and later. Moving forward, Rule B will only be triggered if a property’s intended use changes, i.e., a residential property to a commercial property, or there are significant changes to the property.

The Maricopa County Assessor's Office acknowledges that this court decision and the Notices may raise questions and concerns among property owners. The office is committed to providing transparency and support throughout this process to ensure that property owners clearly understand the changes and their options.

We are offering several virtual public education sessions where our subject matter experts will help property owners understand the changes and their implications. Property owners can register here for one of the options listed below.

Friday, Oct. 6 from 1-3 p.m.
Friday, Oct. 13 from 4-6 p.m.
Friday, Oct. 20 from 8-10 a.m.

Property owners are encouraged to review their Notices of Proposed Correction promptly and respond within 30 days if they choose to contest the correction. If they do not respond after 30 days, we will correct the tax roll as proposed in the Notice of Proposed Correction.

For more information or assistance regarding the Notices of Proposed Correction, affected property owners are encouraged to contact the Maricopa County Assessor's Office at 602-506-3406.

Assessor's Office Named 2023 Top Workplace in Arizona

---

MARICOPA COUNTY, Ariz. (July 14, 2023) - We are thrilled to announce the Maricopa County Assessor's Office has been named a 2023 Top Workplace in Arizona. The list is based solely on employee feedback gathered through Energage’s third-party survey.

The confidential survey uniquely measures 15 culture drivers that are critical to the success of any organization including appreciation, execution, and connection.

Over 84% of our team participated and shared many comments detailing why they believe the Maricopa County Assessor’s Office is a great place to work.

“It has always been important to me that we create a high-performing, highly effective team, but I wanted to make sure they feel valued,” said Maricopa County Assessor Eddie Cook. “The fact that this a top workplace, not just in government but in Arizona, is truly a reflection of everyone’s dedication to this team and our community.”

Being named a Top Workplace is a big deal – only 137 organizations made this year’s list, and it accomplishes one of our office’s top goals in our comprehensive Strategic Plan.

“Earning a Top Workplaces award is a badge of honor for companies, especially because it comes authentically from their employees,” said Eric Rubino, Energage CEO. “That's something to be proud of. In today's market, leaders must ensure they’re allowing employees to have a voice and be heard. That's paramount. Top Workplaces do this, and it pays dividends.”

Notices of Claim Now Accepted Digitally

---

MARICOPA COUNTY, Ariz. (July 11, 2023) - Maricopa County property owners now have another way to virtually access and file a Taxpayer Notice of Claim with our office. A Notice of Claim is a statutory process that allows the property owner to notify the Assessor’s Office when they discover a factual error regarding their property information for up to three years back. This could include wrong information on square footage, improvements, personal property, or legal classification.

As of July 11, 2023, there are two ways to file a Notice of Claim online with the Maricopa County Assessor’s Office. First, through the Assessor’s Office website, property owners can complete and submit one through DocuSign. Property owners can also download and complete the required Department of Revenue Form and email it to the designated inbox, [email protected]. Notices of Claim will still be accepted by mail, but they must be sent by Certified Mail to the following address:

Notices of Claim submitted via email MUST be sent to [email protected] and cannot be accepted if sent to another email address. Our office will respond to the Notice within 60 days from receiving it, whether online via DocuSign or email or Certified Mail. The Assessor’s Office decision, whether to consent or dispute the taxpayer’s Notice, will be mailed in a letter to the property owner’s address or their designated authorized agent. Property owners can submit a Notice of Claim for tax years 2020 to 2023.

This digital option was made possible when SB 1266 was signed into law last year, allowing Notices of Claim and Petitions for Review to be accepted electronically. Maricopa County Assessor Eddie Cook was instrumental in passing the bill, saying, “It has been important to me since Day 1 to find ways that our office can continue to provide the best service to property owners at the lowest expense to the taxpayer. Offering digital solutions along with conventional paper and in-person processes is a top priority.” Since then, our office has been creating the necessary framework and procedures for accepting Notices of Claim online and are excited to debut the new service.

Please contact our office at 602-506-3406 or [email protected] with any questions.
