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. Complete the OIG Electronic Complaint Form

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. 


We cannot provide information regarding what action(s) have been taken on any allegation reported to our office.

The Maryland Public Information Act prohibits the disclosure of information contained in OIG records even to the individual submitting the allegation(s).

Unless you are contacted directly by one of our investigators, there will be no communication from our office outside of correspondence which may advise you that your matter has been referred to another entity. A referral will occur if your submitted allegations does not fall under the jurisdiction or cognizance of the Baltimore City OIG.

Under no circumstances will our office provide you with the status of action taken on any allegation. The information you provide will be processed according to our internal policies and guidelines. Appropriate action will be taken, as determined.
