What We Do 

Background :

Congress enacted the Inspector General Act of 1978 to ensure integrity and efficiency in government. Both the Department of Homeland Security (DHS) Act and this Office of Inspector General (OIG) were established by Congress in 2002. The OIG is led by an Inspector General who is appointed by the President and subject to Senate confirmation.


The OIG conducts and supervises independent audits, investigations, and inspections of the programs and operations of DHS, and recommends ways for DHS to carry out its responsibilities in the most effective, efficient, and economical manner possible. We also seek to deter, identify and address fraud, abuse, mismanagement, and waste of taxpayer funds invested in Homeland Security.


The OIG operates a hotline where DHS employees and others can report fraud, waste, abuse and mismanagement, or other criminal or noncriminal misconduct. The toll-free number to call is 1 (800) 323-8603; Fax at (202) 254-4292. We prefer you use our Hotline Allegation Form, which allows you to report allegations in detail and to include relevant documents and other evidence.
