Online Real Property Protest
Your property was valued as it existed on January 1, 2023. The appraisal data used to establish real property value in Larimer County was from the 24-month period ending on June 30, 2020. The value is based on comparable sales of properties during that period. All property in Colorado is revalued every odd-numbered year. The appraisal data used to establish real property value was from at least the 18-month period ending June 30, 2020 and up to 60 months prior to that date, as necessary.
In 2022, properties with a change of value or a change in ownership received a Notice of Valuation (NOV) postcard via mail on or before May 1, 2022. If you have misplaced the postcard, you can access your NOV online here by entering your Account/Schedule or parcel number. All property owners may protest. Please 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 Assessment Update.
Our online protest system will not be available after 11:59 p.m. on June 8, 2023. Download these instructions (PDF format) to either print or open and view in a separate window to reference while you complete your online protest.
The property tax notice you receive from the Treasurer next January will be based on the 2023 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 and Assessor staff will review requested changes.
