Did you know you can FILE YOUR REAL PROPERTY APPEAL ONLINE?
You may appeal your real property value between May 1st and June 8th per C.R.S. §39-5-122(1). 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. Please use these instructions(PDF, 1008KB) for assistance using the sales search tool.
If you are filing an appeal on commercial or industrial property, you will need to provide additional information(PDF, 109KB) 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, 2024. This date is set by law. We can only consider sales and other market information from 2023 and the first six months of 2024 for values set for 2025 and 2026. If you purchased your property, or if you had an appraisal done after June 30, 2024, we cannot consider it in our review of values for 2025 or 2026. 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 needed, download a sample letter of authorization(PDF, 1MB).
No late appeals of real property can be considered.
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 August 15th.
If the date for filing any report, schedule, claim, tax return, statement, remittance, or other document falls upon a Saturday, Sunday, or legal holiday, it shall be deemed to have been timely filed if filed on the next business day, § 39-1-120(3), C.R.S.
