How to Report Suspected Fraud, Waste, or Abuse to the OIG

The OIG is an independent, non-partisan oversight agency mandated to prevent and detect fraud, waste, and abuse of public resources at the state and municipal level across the Commonwealth.

If you suspect fraud, waste or abuse of public funds or property, we encourage you to contact one of our confidential hotlines. Many of our cases started as hotline tips. 

You are not required to give your name, however, if the investigative team has follow-up questions regarding your complaint and cannot contact you, we may not be able to proceed with an investigation.

By law, all OIG records, including your complaint, are not subject to the public records law and are confidential.  

Confidential translation services are available in most languages for non-English speakers.

The OIG offers two hotlines – one for general complaints of fraud, waste or abuse and the other for complaints related to public transportation, including the MBTA, MassDOT’s Highway Division, the Registry of Motor Vehicles, the Aeronautics Division, and spending by regional transit authorities, cities and towns using state funds for road improvements. 

Both hotlines are confidential and can be accessed by phone, email, online form or mail.

Frequently Asked Questions about Reporting Fraud, Waste or Abuse

What information do I need to provide the OIG to make a complaint?

  • Identify the city, town, agency, or other public entity involved.
  • Provide the name(s) of individual(s) involved, with their positions or titles.
  • Explain the issue or concern in as much detail as possible, including the nature, scope and timeframe of the suspected wrongdoing.
  • Provide us with information about other individuals who may have relevant information or documents, as well as their contact information.
  • Include copies of any related documents that support your claim(s), which can be uploaded in the reporting form, sent via email or mail.

What actions will the OIG take in response to a complaint?

OIG staff review each complaint to determine if it falls within our jurisdiction.

Whistleblower Laws, Retaliation and Intimidation: You May Be Protected

What is a whistleblower?

A whistleblower is a person who exposes suspected fraud, waste, abuse or other misconduct by an individual or organization. Often, a whistleblower is employed by, works with or has some other formal relationship with the alleged wrongdoer. However, that is not always the case. A whistleblower may be a vendor, subcontractor or a concerned member of the public. A person may be considered a whistleblower when they report the misconduct either internally or to an outside watchdog entity, such as the OIG.  

Whistleblowers may be entitled to legal protections from retaliation under state or federal law, provided they follow certain procedures outlined in the whistleblower statutes.

What laws exist to protect whistleblowers?

Massachusetts whistleblower laws are designed to protect people who report information about suspected illegal, wasteful or unethical activity. When you report suspicions regarding illegal activity by an individual or organization to our public fraud, waste and abuse hotline or public transportation fraud, waste and abuse hotline, you and your identity may be protected under state law (M.G.L. c. 12A, § 14(b)). State law also specifically protects you from retaliation by your employer for submitting a complaint or disclosing information to the OIG (M.G.L. c. 12A, § 14(c)).

Other state laws, including the Massachusetts Whistleblower Act (M.G.L. c. 149, § 185), may provide further protections. State law also criminalizes the intimidation of whistleblowers. (M.G.L. c. 268, § 13B).

What is retaliation?

Retaliation occurs when an employer punishes, or threatens to punish, an employee for reporting fraud, waste or abuse, or for cooperating with an investigation of such misconduct. The misconduct may be perpetrated by the employer or another party with whom the employer has a business relationship. 

Retaliation may take the form of an adverse employment action by the employer, including demotion, suspension, denial of a promotion or raise, or firing.  Employees may be entitled to legal protection from retaliation under state or federal law, provided they follow certain statutory procedures.

Retaliatory behavior in other contexts, such as an agency punishing a vendor or a contractor punishing a subcontractor, may be prohibited by state or federal law as well, depending on the circumstances.

State law protects whistleblowers from retaliation.

What is intimidation?

Intimidation is when someone makes a direct or indirect threat, harasses, or attempts to injure or harass a witness or potential witness. In Massachusetts, witness intimidation is a crime. Such behavior against a witness or potential witness in an OIG investigation is illegal. (M.G.L. c. 268, § 13B).
