Welcome to the Office of the Inspector General

The Massachusetts Office of the Inspector General (OIG) promotes good government. We are committed to collaboration at all levels of government to achieve this mission for the Commonwealth of Massachusetts.

The OIG helps prevent and address fraud, waste and abuse in government spending. We carry out investigations at all levels of government and review programs and practices to find areas for improvement. We also provide guidance and educational training on public purchasing, fraud prevention, and other topics designed to help state and local governments to operate effectively and efficiently.
