2026 Appeal Deadline: 60 days from the date the Notice of Value is mailed
In Arizona, you must file your Petition for Review of Real Property Valuation within 60 days after the Assessor mailed your Notice of Value. Notices are typically mailed between February 1 and March 1 each year. The specific deadline date is printed on your Notice of Value card. For 2026 property values, if your notice was mailed in late February 2025, your deadline would be approximately late April 2025.

How Greenlee County Assesses Property
Assessed by: Greenlee County Assessor's Office
Assessment cycle: annual
Notices typically mailed: February-March
In Greenlee County, the Assessor determines your property's Full Cash Value (market value) annually based on comparable sales and property characteristics. Arizona law requires that residential properties be assessed at 10% of their market value to calculate property taxes. For example, if your home's market value is $117,300 (the county median), at Arizona's 10% assessment ratio your assessed value would be $11,730, resulting in approximately $457 in annual taxes at the county's effective rate of 0.39%.
The Appeal Process
Appeals are heard by the County Assessor / State Board of Equalization. If you request a meeting with the Assessor, they will review your evidence and discuss their valuation methodology. At a State Board of Equalization hearing, a mediator hears from both you and the Assessor's office, with each side presenting evidence about the property's value.
Step 1: Review your Notice of Value when it arrives (typically mailed February-March). Check both the Full Cash Value (FCV) and Limited Property Value (LPV). Note that only FCV can be appealed, not LPV.
Step 2: Gather evidence to support your appeal within 60 days of the notice mailing date. This includes comparable sales of similar properties, photos showing property condition, repair estimates for any defects, and your recent purchase price if you bought the home recently.
Step 3: Complete the Petition for Review of Real Property Valuation (Form 82130R for residential or Form 82130 for commercial properties). You can request this form from the Assessor's Office by calling (928) 865-5302, or download it from the Arizona Department of Revenue website.
Step 4: File your petition with the Greenlee County Assessor's Office by mail to PO Box 908, Clifton, AZ 85533, or in person at 253 5th Street, Clifton. You may request an informal meeting with the Assessor's office to discuss your appeal. The Assessor must respond to all appeals by August 15.
Step 5: If you disagree with the Assessor's decision, you may appeal to the State Board of Equalization (SBOE) within 25 days of receiving the Assessor's decision. The SBOE will schedule a hearing where both you and the Assessor present evidence before a mediator.
Step 6: If you remain dissatisfied with the SBOE decision, you may file an appeal with Arizona Tax Court within 60 days of the SBOE decision. All Arizona tax court appeals are heard at Maricopa Superior Court in Phoenix. Alternatively, you can bypass the administrative process and file directly with Tax Court before December 15 of the valuation year.
