Real Property Valuation

Notices of Valuation for real property are mailed on May 1* and are available online through the Notice of Valuation Archive Search. Find more information about how real property is valued on the Real Property Valuation page.

Personal Property Valuation

Business equipment and/or residential rental furnishings, per Colorado statute, are taxable personal property for anyone who owns a business or rents out their furnished residential property on a short term or long term basis.
