Online Real Property Protest

Your property was valued as it existed on January 1, 2019. The appraisal data used to establish real property value in Larimer County was from the 24-month period ending on June 30, 2018. The value is based on comparable sales of properties during that period. All property in Colorado is revalued every odd-numbered year.

For 2019, all property owners were mailed a Notice of Valuation postcard. All property owners may protest. Owners should note that submitting a protest initiates a review of the property value and may result in a higher valuation if warranted. For more information see our Reappraisal Update.

Our online protest system will not be available after 11:59 p.m. on June 3, 2019. Help! How do I protest online? (PDF document of instructions that can be opened and viewed in a separate window to reference while you complete the online protest)

The tax notice you receive next January will be based on the 2019 value.

If you are not protesting the value or classification of the property but would like to make corrections to the property information please send an email with your account information so the Assessor staff can review any requested changes.
