About the Assessor's Office

The Assessment Division is an agency of 53 full-time employees within the Department of Finance. The Assessor directs and oversees the efforts of the five teams: Administration, Business Personal Property, Geographical Information Systems (GIS) Tax Mapping, Information Management and Real Property.

Mission Statement

To fairly and uniformly value all real and business personal property within the City and County of Denver and to comply with the Colorado Constitution, state laws, regulations and the highest industry standards. We will perform all of our duties thoroughly and efficiently and serve the public in a courteous, friendly, and responsible manner.

Duties of the Assessor

Under Colorado law, county assessors calculate the values of all real and business personal property for tax purposes. The annual list of all assessed values is known as the Assessment Roll. The Denver Assessor directs a local team of highly skilled appraisers, analysts, managers and technicians. In addition to determining property values, the Assessment Division:

  • Keeps and updates property ownership data;
  • Maintains maps of tax parcel boundaries;
  • Collects and revises property characteristics (land & improvements);
  • Verifies properties eligible for exemption; and
  • Analyzes trends in property sales, prices, construction and renovation costs and rents for commercial and industrial properties. 
 
State laws and regulations governing the assessment process for Denver and all counties are found in Colorado Revised Statues (C.R.S.), Title 39 and the Assessors Reference Library published on-line by the State Division of Property Taxation. 


Property values listed on the Assessment Roll are used to calculate annual property taxes which are billed and collected by the Denver Treasury Division. The Assessor does not establish tax rates (millages), set taxes, or collect tax payments.
