Rob HartleyRob Hartley·Updated March 5, 2026

The county seat is Flagstaff, which is also the largest city with over 73,000 residents. Other notable cities include Sedona, Page, Williams, and Tuba City. Coconino County is the second-largest county by area in the contiguous United States, encompassing 18,661 square miles and including Grand Canyon National Park and significant portions of Native American reservations. Property tax appeals matter here because homeowners may be paying more than their fair share, with the county's median property tax bill below the national average but still representing a significant annual expense for residents.

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, residential properties are assessed at 10% of their market value for tax purposes. For example, if your home's market value is $335,000, at Arizona's 10% assessment ratio your assessed value would be $33,500, resulting in approximately $1,809 in annual taxes at the county's effective rate of 0.54%. The Notice of Valuation mailed annually in February shows both your Full Cash Value (market value) and your Limited Property Value, which is used to calculate your actual tax bill and typically increases by no more than 5% per year.

The Appeal Process

Appeals are heard by the Coconino County Board of Equalization / Arizona State Board of Equalization / Arizona Tax Court. At the Board of Equalization hearing, you will present your evidence and the Assessor will present theirs. The Board acts as a quasi-judicial body, making decisions based on the evidence presented. Written decisions are mailed to all parties after the hearing.

1

Step 1: Review your Notice of Value received in February showing your property's Full Cash Value and Limited Property Value. Gather evidence such as comparable sales data, photos of property condition, repair estimates, or professional appraisals that support your claim of overvaluation.

2

Step 2: File a written appeal with the Coconino County Assessor's Office within 60 days from the mail date on your Notice of Value. Include supporting documentation with your appeal form showing why you believe the valuation is incorrect.

3

Step 3: The Assessor will review your appeal and supporting evidence. The Assessor must rule on all appeals no later than August 15. You will receive a written decision by mail with the postmark date serving as evidence of when the decision was mailed.

4

Step 4: If you disagree with the Assessor's decision, you may appeal to the County Board of Equalization within 25 days of the date the Assessor's decision was mailed. File with the Clerk of the County Board of Equalization at 219 E. Cherry Ave., Flagstaff, AZ 86001 by 5:00 PM on the deadline. Include copies of your original appeal, attachments, and the Assessor's decision.

5

Step 5: The Board of Equalization will schedule a hearing to review your case and must issue a decision by October 15. If you still disagree with the outcome, you may appeal to the Arizona State Board of Equalization (for large counties) or file directly with Tax Court within 60 days of the Board's decision.

Frequently Asked Questions

What is the deadline to appeal my property taxes in Coconino County for 2026?
You have 60 days from the mail date printed on your Notice of Value to file a property tax appeal in Coconino County. The 2026 Notice of Value was mailed on February 11, 2025, which means your deadline is approximately mid-April 2026. The specific deadline is calculated from the postmark on your individual notice, so check your notice carefully. Missing this deadline means you lose your right to appeal for that tax year, so it's critical to act quickly once you receive your valuation notice.
How do I file a property tax appeal online in Coconino County?
Coconino County does not currently offer a fully online appeal filing system. However, you can access property information and forms through the Assessor's website at www.coconino.az.gov/assessor and the online property database at eagleassessor.coconino.az.gov. To file an appeal, you must submit a written Property Tax Appeal Form along with supporting documentation either by mail to 110 E. Cherry Ave., Flagstaff, AZ 86001, or in person during business hours Monday through Friday from 8:00 AM to 5:00 PM. You can call (928) 679-7962 to request forms or get additional information about the filing process.
What evidence do I need to win a property tax appeal in Coconino County?
To successfully appeal your Coconino County property taxes, you need compelling evidence that demonstrates your property's Full Cash Value is lower than what the Assessor determined. The strongest evidence includes recent comparable sales of similar properties in your neighborhood that sold for less, a professional appraisal showing a lower market value, photographs documenting property damage or defects, contractor estimates for needed repairs, or evidence of errors in your property's recorded characteristics such as incorrect square footage or features. The Assessor's decision must be made by August 15, and all documentation supporting your opinion of value must accompany your appeal when filed within 60 days of your Notice of Value.
What happens at a Coconino County Board of Equalization hearing?
If you disagree with the Assessor's decision on your appeal, you can file with the County Board of Equalization within 25 days. The Board acts as a quasi-judicial body, similar to a judge, and makes decisions based solely on the evidence presented at your hearing. You'll present your evidence and arguments for why your property value should be reduced, and the Assessor's Office will present their evidence supporting their valuation. The Board has the authority to change the value or classification and aims to set a fair and equitable value. Written decisions are mailed to all parties after the hearing, and the Board must rule by October 15. You should bring all supporting documentation including comparable sales, appraisals, and photographs to present your case effectively.
How much can I save by appealing my property taxes in Coconino County?
The amount you can save depends on how much the Assessor overvalued your property and whether your appeal is successful. With Coconino County's 10% assessment ratio and 0.54% effective tax rate, every $10,000 reduction in your property's Full Cash Value translates to approximately $54 in annual tax savings. For example, if you successfully appeal a $350,000 valuation down to $320,000, you would save approximately $162 per year. Statistics show that about 25% of homes in America are overassessed by an average of $1,346 annually. Given that the typical Coconino County property tax bill is $1,766, a successful appeal could potentially reduce your taxes by several hundred dollars annually, and those savings continue year after year.
Can I appeal my property taxes in Coconino County if I just bought my home?
Yes, you can appeal your property taxes even if you recently purchased your home in Coconino County. In fact, a recent purchase price can be strong evidence in an appeal if you bought the property for less than the assessed value. If you became the new owner before December 15 of the valuation year, you may appeal to Tax Court by December 15 of that year. If ownership changed after December 15, you can appeal by December 15 of the year taxes are levied. For regular appeals through the Assessor's Office, the standard 60-day deadline from the February Notice of Value applies regardless of when you purchased the property. Your purchase documents showing the actual sale price are valuable evidence if the Assessor's valuation exceeds what you paid.
What is the difference between Full Cash Value and Limited Property Value on my Coconino County tax notice?
Your Coconino County Notice of Value shows two values: Full Cash Value and Limited Property Value. Full Cash Value represents the property's market value as determined by the Assessor based on comparable sales in your area, and it can increase or decrease by any amount each year based on market conditions. Limited Property Value is the value actually used to calculate your taxes and typically increases by only 5% per year, providing protection against rapid market increases. The Limited Property Value can never exceed the Full Cash Value. You can appeal the Full Cash Value if you believe it's too high, but you cannot appeal the Limited Property Value unless there was a calculation error, as it's determined by statutory formula under Arizona law.
What veteran and senior exemptions are available in Coconino County to reduce property taxes?
Coconino County offers several valuable exemptions that can significantly reduce or eliminate property taxes. Veterans with 100% service-connected disability from the VA qualify for a full exemption on their primary residence, eliminating all property taxes. Veterans with partial disability ratings receive exemptions calculated by multiplying their disability percentage by $4,873 on assessed value. Seniors age 65 and older can apply for the Senior Value Protection Option which freezes their Limited Property Value for three years, protecting against increases. Widow/widower and disabled person exemptions are also available with income restrictions. All individual exemption applications must be filed between January 1 and March 1 each year, while senior freeze applications are accepted through September 1. Contact the Assessor's Office at (928) 679-7962 or visit coconino.az.gov/assessor for application forms and eligibility details.
