Board of Assessment Appeals

Lady justice

The Board of Assessment Appeals (BAA) is a quasi-judicial tribunal consisting of Board members appointed by the governor of Colorado, with the consent of the Colorado Senate. Board members are appraisers who serve as hearing officers, in accordance with the Administrative Procedures Act, to decide appeals from the property valuation and classification decisions of county boards of equalization and county boards of county commissioners, and decisions of the property tax administrator regarding exemptions and state-assessed properties. The BAA may also hear appeals from orders of a county assessor or county board failing to respond to a timely filed taxpayer appeal. The BAA issues orders, conducts hearings, and renders written decisions resolving appeals.
