Internal Audit Reports
The County Auditor performs internal audits of County departments and elected officials. These audits can assess weaknesses in the control over County resources and help to provide DuPage County taxpayers with better services at lower cost. A report of
each audit, detailing the conditions found and the Auditor's recommendations, is distributed to the management of the department, the County Board or Elected Official.
The County Auditor recognizes that it is a difficult balance between providing transparency to the public through internal audit reports and providing insight to those interested in exploiting the County's vulnerabilities for their personal benefit. As
some audit reports identify internal control weaknesses within County operations, audit reports may not be immediately released to the public until the issues have been addressed.
Many of the audit reports presented on this website do not display the attachments and addendums contained in the original audit report. This is to prevent detailed information regarding County operations, internal control weaknesses or personally identifiable
information about County employees from being disclosed.
The County Auditor assigns a number to an audit at the commencement of each audit. In some cases, for a variety of reasons, these audit procedures may not result in an audit report being issued resulting in gaps in the audit numbers noted in the reports.
list of internal audits performed by the County Auditor presented below is updated on a quarterly basis and contains reports issued for a three-year period. As previously noted, internal audits performed during the prior 12 months are not listed on
this website in order to provide an opportunity for the subject of the audit to address the issues identified in the audit. You can receive a copy of any audit report issued prior to this period by sending an
e-mail to email@example.com, by calling 630-407-6075, or by writing to:
Office of the DuPage County Auditor
