Did you know you can FILE YOUR REAL PROPERTY APPEAL ONLINE?
Colorado Statutes identify the month of May as the time for you to contact us concerning your valuation. Please keep in mind that you should provide information to support your estimate of value if it differs from that estimated by the Assessor's Office. Review sales in your area using our sales search tool. Sales Search Tool Instructions(PDF, 3MB).
If you are filing an appeal on commercial or industrial property, you will need to provide additional information(PDF, 97KB) to our appraisers.
The Assessor’s Office will receive property owner protests via Online Electronic Form, email, fax, mail, or a telephone conference (See details below).
Your value is our estimate of the value of the property as of June 30, 2022. This date is set by law. We can only consider sales and other market information from 2021 and the first six months of 2022 for values set for 2023 and 2024. If you purchased your property, or if you had an appraisal done after June 30, 2022, we cannot consider it in our review of values for 2023 or 2024. We may consider appeals for the valuation of the property only, not the amount of taxes you pay.
*Values are based on condition and level of completion as of the January 1 Assessment Date.
During the month of May, you may appeal your property value in several ways:
NOTE: The owner is the only person recognized by law to have "standing" to file a protest. Protests filed by individuals other than the owner or authorized agent may be denied for lack of standing. A letter of agency (written letter of authorization) is required from persons who are not the owner of record but are filing a protest on behalf of the property owner. If you need a sample letter of authorization, please click here.(PDF, 1MB)
No late appeals of real property can be considered.
For 2023, the last day to appeal your value with the Assessor is June 8, 2023. All written appeals must be faxed, postmarked or e-mailed by that date.
All appeals will receive the same diligent review, regardless of the method of submission. A written "Notice of Determination" will be issued for each appeal and will be mailed no later than June 30, 2023.
