​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. In addition to determining values, the assessor: 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 San Juan and all counties are found in the Colorado Revised Statutes (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 County Treasurer. The Assessor does not establish tax rates (millages), set taxes, or collect tax payments.
