File a Complaint

OIG Flowchart


There are several ways to report financial fraud, waste or abuse to the OIG.

  1. Call the hotline at 443-984-3476 or 1-800-417-0430 
  2. Email a completed Complaint Form below to [email protected]
  3. Fill out the Complaint Form below, and mail it to 100 North Holliday Street, Room 635, Baltimore, MD 21202

Complaints and allegations received by the OIG are analyzed to identify criminal, administrative or systemic issues affecting the City of Baltimore. The information received is reviewed and evaluated to determine if an investigation or audit is warranted. If the complaint or allegation does not fall under the OIG’s jurisdiction, the information will be forwarded to the appropriate authority for review.

When reporting fraud, waste, abuse or mismanagement to the OIG, you may remain anonymous if you wish. However, you are encouraged to identify yourself so that we can follow up on your call to obtain additional information that will aid us in our investigation. If you give your name, your identity will be protected to the maximum extent allowed by law. It is impermissible for a government employer to retaliate against an employee for reporting information to the OIG. If you believe that by filing a complaint with the OIG you may be at risk of reprisal, inform the OIG of this fact.

When reporting information to the OIG, be as specific and provide as much detail as possible: the who, what, where, when and why of the matter. The more information you provide, the more thorough any OIG investigation can be.
