Travis BunnTravis Bunn·Updated July 24, 2026

Coconino County is located in north-central Arizona with Flagstaff as its county seat, serving approximately 144,000 residents. It is the second-largest county by area in the contiguous United States, covering 18,661 square miles and encompassing diverse communities from Flagstaff and Sedona to Page and Williams. Property tax appeals are particularly important here because homeowners pay a median annual tax bill of approximately $1,956, and even modest valuation reductions can result in significant savings over time. With a median home value of approximately $468,600, well above the Arizona median of $257,700, Coconino County property values are among the highest in the state. The county's effective property tax rate of 0.48% is notably lower than the national median of 1.02%, making Coconino County's median annual tax bill about $442 lower than the national median of $2,400.

How Coconino County Assesses Property

10%of market value

Assessed by: Coconino County Assessor's Office

Assessment cycle: annual

Notices typically mailed: February

In Arizona, property taxes are calculated using the Limited Property Value, which is multiplied by the 10% assessment ratio for residential properties to determine your assessed value. For example, if your home's market value is $468,600 (the county median), at Arizona's 10% assessment ratio your assessed value would be $46,860, resulting in approximately $2,249 in annual taxes at the county's effective rate of 0.48%. The assessed value is then multiplied by the combined tax rates of all taxing districts (county, school, fire, etc.) that serve your property.

The Appeal Process

Appeals are heard by the County Board of Equalization / Arizona State Board of Equalization. The County Board of Equalization holds hearings where a hearing officer reviews your evidence and the Assessor's valuation. The Board of Supervisors, acting as the Board of Equalization, then votes to accept or reject the hearing officer's recommendation, with review limited to due-process concerns.

1

Step 1: File a Petition for Review with the County Assessor within 60 days of the Notice of Value mailing date using ADOR Form 82130. Include evidence such as comparable sales, photographs, repair estimates, or an independent appraisal to support your claim that the valuation is incorrect.

2

Step 2: The Assessor reviews your appeal and supporting documentation. The Assessor must rule on all appeals no later than August 15. You will receive written notice of the Assessor's decision by mail, with the postmark date serving as evidence of when the decision was mailed.

3

Step 3: If you disagree with the Assessor's decision, file an appeal with the Clerk of the County Board of Equalization at 219 E Cherry Ave, Flagstaff, AZ 86001, phone (928) 679-7144, within 25 days of the date the Assessor's decision was mailed. Forms must be received by 5:00 PM on the deadline date.

4

Step 4: Attend the County Board of Equalization hearing where a hearing officer will review your case. The Board will either uphold the Assessor's valuation or order a reduction. The Board of Supervisors acting as the Board of Equalization will accept or reject the hearing officer's recommendation.

5

Step 5: If you remain dissatisfied, you may appeal to the Arizona State Board of Equalization, which acts as a neutral judge and can change your value or property classification. Alternatively, you can file directly with the Arizona Tax Court within 60 days of receiving the County Board's decision for a judicial review.

6

Step 6: As a final option, file an appeal directly with the Arizona Tax Court. Required forms and information are available from the Arizona Tax Court at (602) 506-8297. This is an independent alternative to the County Board of Equalization process.

Frequently Asked Questions

What is the deadline to appeal my property taxes in Coconino County for 2026?
The deadline to appeal your 2027 property tax assessment in Coconino County is April 13, 2026, which is 60 days from the February 10, 2026 Notice of Value mailing date. You must file your appeal using ADOR Form 82130 with the Coconino County Assessor's Office within this 60-day window. The specific deadline date is printed on your Notice of Value, and U.S. Postal Service postmarks serve as evidence of timely filing. Missing this deadline means you forfeit your right to appeal for that tax year.
How do I file a property tax appeal in Coconino County?
To file a property tax appeal in Coconino County, complete ADOR Form 82130 (Petition for Review of Real Property Valuation) and submit it to the Assessor's Office at 110 E Cherry Ave, Flagstaff, AZ 86001, within 60 days of receiving your Notice of Value. Include supporting evidence such as comparable sales data, photographs of your property, recent appraisals, or repair estimates that demonstrate why your property's assessed value is too high. You can file by mail, in person during business hours (Monday-Friday 8am-5pm), or call (928) 679-7962 for assistance. The Assessor must rule on your appeal by August 15, and if you disagree with their decision, you can escalate to the County Board of Equalization within 25 days.
What is the assessment ratio in Coconino County and how does it affect my taxes?
Coconino County uses Arizona's statutory 10% assessment ratio for residential properties, which means your assessed value equals 10% of your Limited Property Value. For example, if your home has a Limited Property Value of $450,000, your assessed value would be $45,000, and this is the figure multiplied by local tax rates to calculate your bill. This assessment ratio is set by state law and cannot be appealed. However, you can appeal the underlying market value (Full Cash Value) or Limited Property Value if you believe the Assessor's valuation is incorrect. Understanding this ratio is crucial because a $50,000 reduction in market value translates to a $5,000 reduction in assessed value.
What evidence do I need for a successful property tax appeal in Coconino County?
For a successful property tax appeal in Coconino County, you should provide comparable sales data showing recently sold properties similar to yours with lower values, photographs documenting property condition issues or defects, and repair estimates from licensed contractors for needed work. Additional strong evidence includes a recent independent appraisal from a certified appraiser, documentation of functional obsolescence or external factors affecting value, and evidence that the Assessor used incorrect property characteristics. The Assessor encourages property owners to perform careful research and submit copies of all evidence during the initial appeal, as this strengthens your case at each level of review. Make sure all comparable properties are in the same geographic area and have similar characteristics to your property.
What property tax exemptions are available in Coconino County?
Coconino County offers several property tax exemptions including the Widow/Widower Exemption, Total and Permanent Disability Exemption, and Veterans with Disability Exemption, each providing up to $4,873 in assessed value reduction (prorated based on disability percentage for applicable exemptions). The Senior Value Protection Option freezes your Limited Property Value for three years for homeowners age 65 and older who meet income requirements. Applications for individual exemptions must be filed between January 1 and March 1 each year, while the Senior Value Freeze application deadline is September 1. You can only claim one individual exemption, but you may combine an individual exemption with the Senior Value Protection Option if you qualify for both. Contact the Assessor's Office at (928) 679-7962 or visit coconino.az.gov/assessor for eligibility requirements and applications.
Can I appeal directly to Tax Court instead of going through the County Assessor in Coconino County?
Yes, Arizona law allows property owners to bypass the County Assessor and County Board of Equalization and file an appeal directly with the Arizona Tax Court within 60 days of receiving your Notice of Value. This is an alternative path to the standard administrative appeal process through the Assessor and Board of Equalization. However, most property owners start with the County Assessor because it's less formal, doesn't require an attorney, and the Assessor may agree to reduce your value without the need for a court hearing. If you choose to appeal directly to Tax Court, you'll need to follow formal legal procedures and may want to hire an attorney. Contact the Arizona Tax Court at (602) 506-8297 for required forms and filing information.
How much can I save by successfully appealing my property taxes in Coconino County?
The amount you can save by appealing your property taxes in Coconino County depends on how much your assessed value is reduced and your property's specific tax rate. With Coconino County's effective tax rate of approximately 0.48%, every $10,000 reduction in market value saves you approximately $48 per year (accounting for the 10% assessment ratio). For example, if you successfully reduce your home's valuation by $50,000, you would save about $240 annually. Over a multi-year period before the next reassessment, these savings compound significantly. Given that the median home value in Coconino County is $468,600 and median tax bill is $1,956, even a 10% valuation reduction could save nearly $200 per year.
What happens after I file my appeal with the Coconino County Assessor?
After you file your appeal with the Coconino County Assessor using Form 82130, the Assessor's Office reviews your petition and supporting evidence to determine if a valuation adjustment is warranted. The Assessor must issue a written decision no later than August 15, with the decision mailed to you via U.S. Postal Service. If you disagree with the Assessor's decision, you have 25 days from the mailing date to file an appeal with the Clerk of the County Board of Equalization at 219 E Cherry Ave, Flagstaff. The County Board then schedules a hearing where a hearing officer reviews your case and makes a recommendation, which the Board of Supervisors acting as the Board of Equalization votes to accept or reject. Throughout the process, postmark dates serve as official evidence of filing and decision dates.
