All allegations of fraud are investigated. Due to strict confidentiality laws, we cannot confirm or deny an investigation of a worker's compensation fraud submission or disclose any information surrounding an employer or claimant. If so, the Department will decide whether there is a reasonable basis to prove that fraud has occurred and refer the matter to the Wisconsin Department of Justice or local District Attorney for potential prosecution.
To report Worker's Compensation fraud, complete the form below, or mail us at the below P.O. address. Providing your name and contact information are optional and very helpful, but you also may report fraud anonymously.

When reporting fraud, please provide the following information:
Anyone who contacts the Division to report fraud may remain anonymous.
If you leave your name, it will not be used in public reports, but you should assume that your name could become part of a legal record depending on the fraud complaint and actions taken by the department from the alleged fraud complaint.
Generally, the Department will refer the matter to an insurance carrier for investigation. The carrier will be required to report back to the Department the results of its investigation. However, by law (See section 102.125 of the Wisconsin Statutes), an insurer is not required to report back until it is satisfied that making the results of investigation known to the Department will not hurt their ability to handle the worker's compensation claim.
Based on the results of the insurer's investigation, the Department will make a decision about whether there is a reasonable basis to believe fraud has occurred. If so, the Department will refer the case to the Wisconsin Department of Justice or local District Attorney for prosecution.
