On the typical Yuma County home, valued near $255,300 at the county’s effective tax rate of 0.54% to 0.88%, 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.

Property owners must file their appeal within 60 days after the Notice of Value card was mailed by the County Assessor.

How Yuma County Assesses Property
Assessed by: Yuma County Assessor's Office
Assessment cycle: annual
Notices typically mailed: February through March 1
In Yuma County, property taxes are calculated based on your property's assessed value, which is determined by applying Arizona's statutory 10% assessment ratio to the property's full cash value (market value). For example, if your home's market value is $255,300 (Yuma County's median), your assessed value would be $25,530 (10% of market value), resulting in approximately $1,370 in annual property taxes at the county's effective rate of 0.54%. Assessment notices are typically mailed by March 1 each year and contain both your full cash value and limited property value.
The Appeal Process
Appeals are heard by the Yuma County Board of Equalization (Board of Supervisors) / Arizona State Board of Equalization. The Board of Equalization hearing is a formal proceeding where both you and the assessor present evidence. The Board's function is to ensure your assessment was made fairly and equitably compared to similar properties, not to determine property values themselves.
Step 1: File a Petition for Review of Valuation (DOR Form 82130R for residential or Form 82130 for other real property) with the Yuma County Assessor's Office within 60 days of the Notice of Value mailing date. Include supporting evidence such as comparable sales data, photos of property condition, or appraisals.
Step 2: The Assessor will assign someone to review your petition and may schedule an appointment to physically inspect the property to ensure all valuation components are correct. After the review is completed, you will be notified of the results.
Step 3: If you are not satisfied with the Assessor's decision, you may schedule a meeting with the Assessor or their representative to further discuss your appeal. This informal meeting often results in an immediate decision.
Step 4: If you still disagree with the Assessor's valuation after the informal meeting, you may file your appeal with the Yuma County Board of Equalization (comprised of the Board of Supervisors). The filing must be done within the deadlines established by law, and your presence at the hearing is required unless all parties have agreed otherwise.
Step 5: At the Board of Equalization hearing, both parties present evidence. The Board's function is to ensure your assessment was made fairly and equitably compared to similar properties. If dissatisfied with the Board's decision, you may appeal to the Arizona State Board of Equalization or directly to Tax Court.
Step 6: If dissatisfied with the State Board of Equalization's decision, you may appeal to Tax Court within 60 days after the date of mailing of the State Board's final decision. Appeals to Tax Court must be filed by December 15th.
