In an effort to slow the spread of COVID-19 in our community, for your safety and our team’s safety, the Eagle County Assessor’s Office will continue to restrict in person interactions through May. If you wish to appeal your property value or classification, please be aware that the current 2020 value is based on June 30, 2018 market data. Unless there is a change in our State Constitution or statutes we cannot accept appeals based on taxes or effects on property value due to the public health situation. As it stands now, any subsequent economic impacts of the virus will be addressed in the 2021 revaluation of all real property.

Real Property Valuation - Intervening Year (even numbered years)

Colorado law requires a two year reassessment cycle for all property.  2019 was the first, or reappraisal year of the current two year cycle. For most property, the valuation for assessment for the 2020 tax year will be the same as it was for 2019. The Assessor is required to notify you of your value each year for real property. For those properties not changing in value during the 2020 intervening year, the value listed on your tax bill, received in January, is the Assessor's notification of value for the coming year. If for any reason we change the valuation for the 2020 tax year, we will mail a Notice of Valuation to you on May 1, 2020. Each notice will describe the property you own, give the actual for both the prior and current year, and provide an opportunity for you to present your objection to the Assessor.

Continuing the efforts of the Assessor's Office to ensure that Eagle County's taxpayer dollars are spent in the most effective and conscientious manner, we have chosen to use an economical postcard format for our Notices of Valuation. In order to save postage and printing costs, the postcards will outline basic property information, i.e., owner name, property location and value change.  The deadlines for appeal are statutorily driven. If you feel the value the Assessor has placed on your property is incorrect, you may wish to inspect the Assessor’s records on your property and other properties. Records on land and buildings are public information, and you have the right to examine them. You have the right to appeal your value each year. May of each year is set aside for the Assessor's Office to hear appeals on property valuation. 

The appraisal data used to establish real property value was from the 24-month period ending June 30, 2018. If data is insufficient during this time period, assessors may use data from the five-year period ending June 30, 2018.

Your property was valued as it existed on January 1 of the current year. The "current year actual value" represents the actual value of your property. The tax notice you receive next January will be based on this value.

An assessment percentage will be applied to the actual value of your property before property taxes are calculated.

The assessment percentage for residences is 7.15. Generally all other property (including vacant land, commercial, and agricultural, as well as natural resources) is assessed at 29 percent. 39-1-104(1) and (1.5)(a), C.R.S.

Property taxes are determined by multiplying the total actual value times the appropriate assessment rate (7.15 or 29 percent), to determine the assessed or taxable value. The assessed value is multiplied by the aggregate total mill levy for the property's tax area to determine total property tax amounts.

The formula for approximating your tax bill amount is as follows: 

assessed value x mill levy = taxes due 

If you receive a Notice of Valuation this year, study it carefully. Visit our website to check the elements of your property such as land size, square footage, bedroom and bathroom counts to make sure that Assessor's Office records are correct. If you see inaccuracies or feel that the value placed on your property is incorrect, you have the right to appeal.

If you are questioning your tax amount or tax rates, please contact the specific taxing entities to communicate your concerns.

In accordance with Colorado law, beginning May 1, 2020, the Assessor’s Office will accept appeals of the valuation or classification of property until June 1, 2020.  In an effort to slow the spread of COVID-19 in our community, we are restricting in-person interactions through May and urging our property owners to submit real property appeals online.  If unable to submit online, you may use USPS, FedEx, UPS, fax or drop your appeal submittal off in an Eagle County dropbox.  For an appeal to be successful, the owner should provide an appraisal dated in the six months prior to June 30, 2018, evidence of details of sales from the subject or comparable properties, or information correcting the details of the property that the Assessor may not know.  A follow-up inspection of the property may be necessary. 

To appeal the value of a property, the person appealing must be either the owner of record, an attorney, or an assigned agent for the owner. Examples of assigned agents are: relatives, tax consultants, presidents of corporations and managers or presidents of condominium associations. If you are appealing property as an assigned agent, please fill out a Letter of Agency, and have it signed by the owner of the property. If the property is owned by a corporation or company, please fill out a Corporate Letter of Agency
