Pinal County Property Tax Appeal, Arizona

Travis BunnTravis Bunn·Updated July 24, 2026

Pinal County is located in central Arizona with Florence as its county seat and a 2026 population of approximately 563,000, making it the state's third-largest county. The county includes major cities such as Casa Grande, Maricopa, Apache Junction, Eloy, and Coolidge, and is experiencing rapid suburban growth from both Phoenix and Tucson. Property tax appeals matter in Pinal County because while the effective tax rate of approximately 0.52% remains below the national median of 1.02%, even a 10% over-assessment on the median home value means homeowners overpay hundreds of dollars annually. The county's median annual property tax bill of approximately $1,615 is below the national median of $2,400, but Pinal County has one of the higher primary property tax rates among Arizona counties at $3.36-$3.45 per $100 of assessed value.

On the typical Pinal County home, valued near $312,100 at the county’s effective tax rate of 0.52%, an over-assessment of even 10% means you are overpaying year after year until you appeal it. Here is how to find out if yours qualifies.

2026 Appeal Deadline: 60 days from the date the Notice of Valuation was mailed (typically April 15, 2025 for 2026 valuations)

Property owners have 60 days from the mailing date shown on their Notice of Valuation to file an administrative appeal with the Pinal County Assessor's Office.

How Pinal County Assesses Property

10%of market value

Assessed by: Pinal County Assessor's Office

Assessment cycle: annual

Notices typically mailed: February (no later than March 1)

In Arizona, residential properties are assessed at 10% of the full cash (market) value to determine the assessed value used for tax calculations. Property taxes are calculated based on the Limited Property Value (LPV), which cannot increase more than 5% per year in most cases. For example: If your home's market value is $312,100 (the county median), at Arizona's 10% assessment ratio your assessed value would be $31,210, resulting in approximately $1,622 in annual taxes at Pinal County's effective rate of 0.52%.

The Appeal Process

Appeals are heard by the County Assessor / County Board of Equalization / State Board of Equalization / Arizona Tax Court. After filing your petition, the Assessor's office may schedule an informal meeting with an appraiser to review your evidence and discuss your concerns. If the matter is not resolved, it proceeds to a formal hearing before the County Board of Equalization where you can present evidence and testimony under oath.

1

Step 1: Review your Notice of Valuation mailed in February to confirm the Full Cash Value (FCV) and Limited Property Value (LPV). Note the mailing date, your 60-day appeal deadline begins from that date.

2

Step 2: Gather evidence to support your appeal, including comparable sales of similar properties in your area, recent independent appraisals, photos documenting property condition issues, or repair estimates for defects that reduce value.

Step 3: Complete Form 82130R for residential property (or Form 82130 for other property types). You must state the valuation method you're using, market approach with comparable sales, cost approach with rebuild costs plus land value, or income approach, and provide substantial supporting information.

Step 4: File your Petition for Review with the Pinal County Assessor's Office within 60 days of the notice mailing date. You can mail it to P.O. Box 709, Florence, AZ 85132, or deliver it in person to any Assessor's Office location. There is no filing fee for administrative appeals.

Frequently Asked Questions

What is the deadline to appeal my property taxes in Pinal County for the 2026 tax year?
The deadline to file an administrative appeal with the Pinal County Assessor's Office is 60 days from the date your Notice of Valuation was mailed. For the 2026 tax year, valuation notices were mailed in February 2025, making the typical deadline April 15, 2025. The exact deadline depends on when your specific notice was mailed, so check the mailing date on your Notice of Valuation. If you missed the administrative appeal deadline, you still have the option to appeal directly to the Arizona Tax Court on or before December 15, 2025, though this process is more expensive and complex than filing with the Assessor's Office.
How do I file a property tax appeal in Pinal County?
To file a property tax appeal in Pinal County, you must complete Form 82130R for residential property (or Form 82130 for commercial/other types) and submit it to the Assessor's Office within 60 days of your notice mailing date. You can mail the form to P.O. Box 709, Florence, AZ 85132, or deliver it in person to the main office at 31 N Pinal Street in Florence or satellite offices in Apache Junction, Casa Grande, Maricopa, or San Tan Valley. There is no filing fee for administrative appeals. The form requires you to specify your valuation method (market approach, cost approach, or income approach) and provide substantial supporting evidence such as comparable sales, an independent appraisal, or documentation of property defects.
What is the difference between Full Cash Value and Limited Property Value in Pinal County?
Full Cash Value (FCV) represents your property's market value as determined by the Pinal County Assessor, while Limited Property Value (LPV) is the capped value used to calculate your actual property taxes. Arizona law limits LPV increases to no more than 5% per year under Proposition 117, even if your FCV increases by more. Property taxes are calculated using the LPV, not the FCV. However, when you file an appeal, you can only challenge the Full Cash Value because the Limited Property Value is calculated based on a statutory formula. If you successfully reduce your FCV through an appeal, your LPV will be recalculated accordingly, potentially lowering your property tax bill.
What evidence do I need for a successful property tax appeal in Pinal County?
The most effective evidence for a Pinal County property tax appeal includes comparable sales of similar properties in your neighborhood that sold within the past year showing lower values than your assessment. You should also consider obtaining a recent independent appraisal from a licensed appraiser, taking photographs that document property defects or damage, and collecting contractor estimates for needed repairs or deferred maintenance. If using the market approach (most common for residential), you must provide the full cash value of at least one comparable property within the same geographic area. The Assessor's office reviews substantial evidence, so the more detailed and relevant documentation you provide, the stronger your appeal will be.
How much is the widow/widower exemption worth in Pinal County?
The widow/widower exemption in Pinal County reduces your assessed property value by $4,873 for the 2026 tax year, which translates to approximately $150-$500 in annual tax savings depending on your local tax rate. To qualify, you must be an Arizona resident for at least 6 months, your total assessed limited property value statewide cannot exceed $36,454, and your household income cannot exceed $39,865 (without children under 18) or $47,826 (with children under 18). Applications must be filed between the first Monday in January and March 1 annually at the Pinal County Assessor's Office. First-time applicants must apply in person and bring a copy of their spouse's death certificate.
What happens at a Board of Equalization hearing in Pinal County?
If the Pinal County Assessor denies your administrative appeal in whole or in part, you can appeal to the County Board of Equalization within 25 days of the Assessor's decision mailing date. At the Board hearing, you'll have the opportunity to present your evidence and testimony under oath, similar to a court proceeding but less formal. The Assessor's office will also present their evidence supporting the valuation. The Board, comprised of the County Board of Supervisors, will review all evidence and testimony before issuing a written decision. If you're dissatisfied with the Board's decision, you can appeal to the Arizona Tax Court within 60 days of the decision date, but no later than December 15 of that year.
Can seniors get property tax relief in Pinal County?
Yes, Pinal County offers several property tax relief options for seniors. The Senior Property Valuation Protection Option (Senior Freeze) is available to homeowners age 65 or older who have lived in their primary residence for at least 2 years and whose average income over the past 3 years is below approximately $43,733-$47,712. This program freezes your Limited Property Value for three renewable years, preventing tax increases from rising property values. Seniors may also qualify for the widow/widower or disability exemption worth $4,873 in assessed value reduction if they meet income and property value limits. Applications for the Senior Freeze are due by September 1, while exemption applications are due between the first Monday in January and March 1 annually.
How is the 10% assessment ratio applied in Pinal County?
Pinal County, like all Arizona counties, assesses residential properties at 10% of the full cash (market) value to determine the assessed value. For example, if your home has a market value of $312,100 (the county median), your assessed value would be $31,210. However, your actual property taxes are calculated based on the Limited Property Value (LPV), not the full assessed value, and the LPV can only increase by a maximum of 5% per year under state law. The assessed value is then multiplied by the combined primary and secondary tax rates for all local taxing authorities serving your property. Understanding this distinction is important when appealing because you challenge the Full Cash Value, which then affects the assessed value and ultimately your Limited Property Value.
