Office of the Inspector General (OIG)

The Office of the Inspector General (OIG) is an independent agency that prevents and detects fraud, waste and abuse of public funds and public property and promotes transparency and efficiency in government. We serve the residents of Massachusetts, state and local governments, and those who work with the government.

The OIG Offers American Rescue Plan Act (ARPA) Resources

Under ARPA, passed by the federal government in March 2021, Massachusetts state, county, tribal and local entities will receive federal aid to respond to the public health and economic impacts of the public health emergency created by the COVID-19 pandemic. The OIG has compiled a resource guide related to ARPA from our Office, the federal government, other state agencies and private organizations.
