Eagle County Property Tax Appeal, Colorado

Travis BunnTravis Bunn·Updated July 22, 2026

Eagle County is located in the heart of Colorado's Rocky Mountains and is home to world-renowned ski resorts like Vail and Beaver Creek. As of 2026, the county has a population of approximately 53,947 residents. Property tax appeals are particularly important here because while Eagle County has a median home value of $728,400, significantly higher than the state median of $237,800, its effective tax rate of 0.40% to 0.42% is lower than the state median of 0.50% and well below the national median of 1.02%. However, due to the high property values, Eagle County homeowners still pay a median annual tax bill of $2,908, which is $1,279 above the national median of $1,629.

On the typical Eagle County home, valued near $728,400 at the county’s effective tax rate of 0.40%, 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.

How Eagle County Assesses Property

6.25%of market value

Assessed by: Eagle County Assessor's Office

Assessment cycle: biennial

Notices typically mailed: May 1 (first week of May)

Eagle County assesses property on a two-year reassessment cycle, with 2025 being a reappraisal year and values typically held for the 2026 tax year. Colorado law requires the Assessor to apply a 6.25% assessment ratio to your property's market value to calculate the assessed value. For example: If your home's market value is $728,400 (the county median), at Colorado's 6.25% assessment ratio your assessed value would be $45,525, resulting in approximately $2,908 in annual taxes at the county's effective rate of 0.40%.

The Appeal Process

Appeals are heard by the County Board of Equalization. If your appeal proceeds to the County Board of Equalization, independent hearing officers experienced in property valuation will conduct 15-minute hearings. You will have 5 minutes to present your case, the Assessor's representative will have 5 minutes, and the remaining 5 minutes are reserved for rebuttal and questions from the hearing officer.

1

Step 1: Review your Notice of Valuation carefully when you receive it in early May. The notice shows your property's actual value for both the current and prior year and provides the basis for your appeal rights.

2

Step 2: Gather evidence to support your appeal between May 1 and June 8, 2026. This should include comparable sales from properties sold within six months prior to June 30, 2024, photos showing property condition, repair estimates, or documentation correcting property details the Assessor may not know.

3

Step 3: File your appeal online (preferred), by mail, fax, in-person, or email no later than June 8, 2026. If mailing, ensure your appeal is postmarked by June 8, 2026. Include your written authorization if appointing an agent to represent you.

4

Step 4: Wait for the Assessor's Notice of Determination, which will be mailed by July 10, 2026. The Assessor's office will review your evidence and may conduct a follow-up property inspection if necessary.

5

Step 5: If you are dissatisfied with the Assessor's decision, you may appeal to the County Board of Equalization by July 20, 2026 for personal property or by July 15, 2025 for real property (check current year deadlines with CBOE).

6

Step 6: If unsatisfied with the County Board of Equalization decision, you may appeal to the State Board of Assessment Appeals or to District Court within the statutory time frames specified in the CBOE decision notice.

How do I file a property tax appeal online in Eagle County?
Eagle County strongly encourages property owners to file appeals online through their automated online form system. You can access the online appeal portal through the Eagle County Assessor's website at https://www.eaglecounty.us/departments___services/assessor/appeals.php.

Box 449, Eagle, CO 81631, by fax to 970-328-8667, or by email to assessor@eaglecounty.us.
What is the senior property tax exemption worth in Eagle County?
The senior property tax exemption in Eagle County exempts 50% of the first $200,000 of your home's actual value, which means up to $100,000 in actual value is exempted from property taxation. The State of Colorado pays the property taxes on the exempted value. To qualify, you must be at least 65 years old on January 1, have owned your home for at least 10 consecutive years, and occupied it as your primary residence for at least 10 consecutive years. Once approved, the exemption remains in effect until a disqualifying event occurs, and you do not need to reapply. The application deadline is July 15.
What happens at a Board of Equalization hearing in Eagle County?
If you appeal the Assessor's decision to the Eagle County Board of Equalization, your case will be heard by independent hearing officers experienced in property valuation. Each hearing lasts 15 minutes total: you have 5 minutes to present your argument and evidence, the Assessor's representative has 5 minutes to respond, and the final 5 minutes are reserved for rebuttal and questions from the hearing officer. All supporting evidence must be uploaded through the online portal before your hearing to be considered. The Board must notify you in writing of its decision within five business days. Due to statutory time frames, hearings cannot be rescheduled, so attendance is critical.
How much can I save by appealing my property taxes in Eagle County?
Successful property tax appeals in Eagle County save homeowners an average of $1,047 per year according to recent data. One local tax appeal service reported that their clients from the 2023 tax valuation achieved an average tax savings of $7,115 over the two-year assessment cycle. The amount you can save depends on how much your property is overvalued and the strength of your evidence. Since Eagle County operates on a two-year reassessment cycle, any reduction in value achieved in a reappraisal year applies to your property taxes for two consecutive years, doubling your total savings.
What evidence do I need for a successful Eagle County property tax appeal?
For a successful appeal in Eagle County, you should provide an appraisal dated within six months prior to June 30, 2024 (the valuation date), evidence of comparable property sales from similar properties in your neighborhood, photographs documenting property condition or defects, repair estimates for needed work, or documentation correcting property details the Assessor may have recorded incorrectly. The Assessor's office will only consider appeals related to property valuation, not the amount of taxes you pay or mill levies. Strong comparable sales evidence showing similar properties sold for less than your assessed value is particularly effective. A follow-up inspection of your property may be necessary during the review process.
When will I receive my property tax assessment notice in Eagle County?
Eagle County mails Notices of Valuation during the first week of May each year. The county uses an economical postcard format that outlines basic property information including owner name, property location, and value changes. Colorado law requires the Assessor to notify you of your property's value each year for real property, showing both the prior year's value and the current year's actual value. The notice also provides information about your right to appeal. For 2026, since it is an intervening (even-numbered) year in the two-year reassessment cycle, typically only properties that changed in value receive notices, but you can always access your property information online through the county's property record search system.
Can I appeal my Eagle County property taxes if I disagree with the Board of Equalization decision?
Yes, if you are dissatisfied with the Eagle County Board of Equalization's decision, you have additional appeal options. You can appeal to the State Board of Assessment Appeals or file an appeal in District Court. The County Board of Equalization must notify you in writing within five business days of its decision, and that notice will include instructions on how to proceed with further appeals and the statutory deadlines you must meet. It's important to note that each level of appeal has strict time limits, so you must act quickly if you wish to pursue your case beyond the county level. Many property owners choose to work with a professional tax agent or attorney for state-level appeals.
