BOE Protest Process

A taxpayer may choose to appeal the decision of the Assessor's Office concerning the value of property for the current year. The taxpayer may appeal to the Board of Equalization by filing the petition on the Notice of Determination form provided by the assessor.

2019 Reappraisal Value and 2020 Intervening Year Information

2019 is a reappraisal year. In a reappraisal year, state statutes require all assessors to revalue all properties. All real property owners will receive a Notice of Value in May 2019. The market approach to value must be used to determine the value of residential properties. State statute requires that the market value of a home is to be determined by sales of comparable residential properties that occurred from July 1, 2016 through June 30, 2018, for the 2019 reappraisal and the 2020 intervening year.

Protesting Value

  • 2020 APPEAL FORM
    In an intervening year, only properties with changes in value received a mailed Notice of Value. All real property owners have the right to appeal each year during the appeal period which this year is May 1, 2020 through June 1, 2020. Please use the 2020 Appeal Form to protest your 2020 value if you did not receive a 2020 Notice of Valuation.
 By Colorado statute, only sales from July 1, 2016 through June 30, 2018 can be used to protest the value. Qualified comparable sales can be accessed using the links above. Sales are listed by subdivision. Sales can also be viewed on public computers at the George Di Ciero City and County Building at:
1 DesCombes Drive
Broomfield, CO 80020

Sales that have occurred after June 30, 2018 can not be used to protest a value. Listings can not be used to protest the value. Sales that have occurred after June 30, 2018 will be used in the 2021 reappraisal.
