Travis BunnTravis Bunn·Updated July 24, 2026

Yuma County is located in southwestern Arizona along the California and Mexico borders, with its county seat in the city of Yuma. The county has a population of approximately 230,000 residents and is known for its agriculture, sunny climate, and historic heritage. Yuma County property owners face a median annual tax bill of approximately $1,106 to $1,370, which is well below the national median of $2,400. With an effective property tax rate ranging from 0.54% to 0.88%, Yuma County residents pay significantly less in property taxes compared to the national average of 1.02%, making property tax appeals especially valuable for those who believe their assessments are too high.

How Yuma County Assesses Property

10%of market value

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.

1

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.

2

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.

3

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.

4

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.

5

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.

6

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.

Frequently Asked Questions

What is the deadline to appeal my property taxes in Yuma County for 2026?
You must file your property tax appeal within 60 days from the date your Notice of Value card was mailed by the Yuma County Assessor. The exact deadline date is printed on your assessment notice, which is typically mailed in February or March each year. For example, if your notice was mailed on March 1, 2026, your appeal deadline would be April 30, 2026. Missing this deadline can result in dismissal of your appeal without further appeal rights, meaning you would have to wait until the next tax year to challenge your assessment. It's critical to act quickly once you receive your Notice of Value to ensure you have adequate time to gather evidence and prepare your appeal.
How do I file a property tax appeal in Yuma County?
To file a property tax appeal in Yuma County, complete a Petition for Review of Valuation form (DOR Form 82130R for residential properties or Form 82130 for other real property) and submit it to the Assessor's Office within 60 days of receiving your assessment notice. You can file in person at the Assessor/Treasurer Building at 197 S. Main Street in Yuma during weekday business hours (8 a.m. to 5 p.m.), mail your petition to the same address, email it to assr-info@yumacountyaz.gov, or call (928) 373-6040 to request the form. Include supporting evidence such as comparable sales data showing similar homes sold for less, photos documenting property condition issues, or documentation of incorrect property characteristics like wrong square footage. You may also request an informal meeting with the assessor to discuss your concerns before proceeding to a formal hearing.
What is the homestead exemption worth in Yuma County?
Arizona does not offer a traditional homestead exemption that reduces property taxes for all homeowners. However, Yuma County residents may qualify for individual exemptions if they are widows/widowers, totally and permanently disabled, or disabled veterans. For 2026, the widow/widower and disability exemptions provide a $4,873 assessed value reduction, which can lower your tax bill by approximately $150 to $500 depending on your local tax rate. Veterans with 100% service-connected disability can receive a full exemption of their primary residence with no cap, effective January 1, 2026. To qualify, you must meet income limits of $39,865 total household income (or $47,826 with minor children), and your total assessed property value cannot exceed $36,454. Applications must be filed between January 2 and March 1 annually.
What happens at a Board of Equalization hearing in Yuma County?
The Board of Equalization hearing in Yuma County is a formal proceeding where both you and the assessor present evidence to support your respective positions on the property's value. The Board is comprised of the Yuma County Board of Supervisors (or appointed hearing officers), and their function is to ensure your assessment was made fairly and equitably compared to similar properties in your area, not to determine property values themselves. Your presence at the hearing is required unless all parties have agreed otherwise. You should bring evidence such as comparable sales data, photographs of property condition issues, appraisals, or documentation of incorrect property characteristics. After hearing both sides, the Board will issue a decision. If you disagree with the Board's decision, you may appeal to the Arizona State Board of Equalization or directly to Tax Court by December 15th.
How much can I save by appealing my property taxes in Yuma County?
Successful property tax appeals in Yuma County save homeowners an average of $456 per year. On the typical Yuma County home valued near $255,300 at the county's effective tax rate of 0.54%, an over-assessment of even 10% means you are overpaying approximately $137 per year until you appeal it. The exact savings depend on how much your assessment is reduced and your property's specific tax rate, which varies by location within the county due to different school district levies and special assessment districts. These savings compound year after year because property tax assessments carry forward to future years, so correcting an overvaluation now can result in thousands of dollars in cumulative savings over the life of your homeownership. Given that the average reduction is $456 annually and appeals have no upfront cost if you file yourself, the potential return on investment is substantial.
What evidence do I need for a Yuma County property tax appeal?
For a successful property tax appeal in Yuma County, you need evidence proving that your property's full cash value (market value) is incorrect or that your property characteristics are stated incorrectly on your assessment record. The most effective evidence includes comparable sales data from at least three similar homes in your neighborhood that sold recently for less than your assessed value, showing the property address, sale price, and date of sale. You should also provide photographs documenting property condition issues such as needed repairs, outdated features, or damage that affects value. If your property record shows incorrect information like wrong square footage, lot size, number of bedrooms or bathrooms, bring documentation proving the correct details. A recent independent appraisal can be powerful evidence, as can repair estimates from licensed contractors for significant defects. For income-producing properties, income and expense statements demonstrating that the property's income-producing capability doesn't support the assessed value can be compelling evidence.
Can I appeal my Yuma County property taxes online?
Yuma County does not currently offer a dedicated online portal for filing property tax appeals electronically. However, you can email your Petition for Review of Valuation form (DOR Form 82130R for residential or Form 82130 for other real property) along with supporting documentation to assr-info@yumacountyaz.gov within the 60-day appeal window. You can also file in person at the Assessor/Treasurer Building at 197 S. Main Street in Yuma during business hours (8 a.m. to 5 p.m. on weekdays) or mail your petition to the same address. You can download the required appeal forms from the Arizona Department of Revenue website or the Yuma County Assessor's website at https://www.yumacountyaz.gov/government/assessor. You can also view your property's assessment information and history through the county's online property search portal at https://yumacountyaz-assessor.tylerhost.net/assessor/web/, which provides current ownership, sales information, tax history, and assessment details.
What is the difference between full cash value and limited property value in Yuma County?
In Yuma County, your Notice of Value shows both a full cash value and a limited property value, and understanding the difference is crucial for property tax appeals. The full cash value is the assessor's estimate of your property's market value - what it would sell for on the open market. The limited property value is a calculated figure based on Arizona's Proposition 117, which restricts annual increases to 5% regardless of market appreciation (unless new construction increases value by more than 15%). Your property taxes are calculated based on the lower of these two values at the 10% assessment ratio. For example, if your full cash value is $300,000 but your limited property value is $250,000, your taxes are based on $250,000. Both values can be appealed if you believe they are incorrect, though the limited value calculation is statutory and not subject to discretionary adjustment by the assessor. Most successful appeals focus on challenging the full cash value when it exceeds true market value.
