The mission of the County Treasurer is to collect all revenues on behalf of those public sector entities which use the property tax as a source of revenue.


The County Treasurer functions as the County's banker: receiving, investing, and disbursing monies in accordance with applicable state statutes. The Treasurer also handles public tax sales, mobile homes, and related issues. There is more information available at the State of Colorado Treasurer's Office website.
