Who we serve

The OIG serves the residents of Massachusetts, state and local governments, and those who work with the government. The OIG investigates crimes involving public funds and identifies waste and abuse in government spending. Anyone may call the OIG’s confidential hotlines to report suspected fraud, waste or abuse of taxpayer funds: you do not have to give your name. The OIG also provides trainings, manuals, guides and other assistance to help state and local agencies run more efficiently and use public funds appropriately.
