Did your property assessment change drastically this year? You're not alone. Below is the appeals process and what you can to do to object to your assesment with the county. 

You have a fairly short window to object. If you plan on objecting you only have until JUNE 8, 2023. 

Appeals process

Land & Improvements

  • Colorado statutes define "Improvements" as: "Improvements" means all structures, buildings, fixtures, fences, and water rights erected upon or affixed to the land, whether or not title to such land has been acquired. 39-1-102(7), Colorado Revised Statutes (CRS).
  • The appraisal data used to establish real property value was from the 48-month period ending June 30, 2022. If data is insufficient during this time period, assessors may use data from the five-year period ending June 30, 2022.
  • 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 2023 for residences is 6.765%; with a value adjustment of -$15,000. Generally all other property, including Vacant Land, Commercial and Natural Resources, is assessed at 27.9%.  A value adjustment of -$30,000 is applied to Commercial properties. The passing of SB21-293 sets renewable energy personal property and agricultural property assessment rate for 2023 at 26.4%.
  • Property Taxes are determined by multiplying the total actual value times the appropriate assessment rate, to determine the assessed or taxable value. The assessed value is multiplied by the aggregate total mill levy to determine total property tax amounts. The Assessor's primary responsibility is to locate, identify, and value all of the taxable property in his jurisdiction.
  • State law requires the Assessor to notify each owner of Real Property by mailing a Notice of Valuation on or before May 1st.
