Welcome to the Colorado Office of the State Auditor (OSA), where our mission is to improve government for the people of Colorado.
The OSA is a nonpartisan agency in Colorado's Legislative Branch. Our performance, financial, and IT audits provide the General Assembly, agencies, and the public with thorough, credible, and impartial assessments of the operation of state programs and the use of state and federal funds. Our audits provide solution-based recommendations that focus on reducing costs, increasing efficiency, promoting the achievement of legislative intent, improving effectiveness of programs and the quality of services, ensuring transparency in government, and ensuring the accuracy and integrity of financial and other information that decision makers need to hold government agencies accountable for the use of public resources.
We invite you to review our audit reports and other information on our website. Our staff are happy to assist you if you have further questions.
