The county assessor is responsible for discovering, listing, classifying and valuing all property within Broomfield in accordance with state law. The Colorado law stresses fairness and all county assessors, including Broomfield's, are bound by the law. Learn more about the Valuation Process.

One of the revenues that Colorado counties have to use in providing services is property tax. Mill levies are set by taxing entities and the amounts collected are derived from the values of real property and commercial personal property as determined by assessors. These values are used to create the property tax revenues that support schools, fire protection, roads, special districts and other local services. All of the revenue generated by property taxes stays within your county. Property taxes do not support state services.

Appeal Information

If you disagree with the assessor's valuation of your property, you may appeal the value by emailing, coming into the Citizens Assistance Center office or mailing the appeal form that is included with the Notice of Valuation. To read more and review sales, please visit the Appeal Information page.
