Assessment Audit

Each year, the State of Colorado contracts for a property assessment study designed to help ensure that property in Colorado is valued correctly for tax purposes. Various provisions of the Colorado Constitution and Colorado Revised Statutes govern the study. Notably, Section 39-1-104 (16), C.R.S., requires that the study be completed and a final report submitted to the General Assembly and the State Board of Equalization by September 15, 2023.
