Anyone with information about an alleged federal tax law violation, including a suspected violation of the prevailing wage and apprenticeship requirements, can report the suspected violation to the IRS by submitting a Form 3949-A, Information Referral PDF.
Useful information to include with the form includes:
• The nature of the suspected violation(including key words such as “prevailing wage” and/or “apprenticeship” in the “Comments” section);
• Any specific information or evidence about the failure to comply with the prevailing wage and apprenticeship requirements;
• Name or employer identification number of the employer (if available); and
• Address of the job site.
The IRS takes referrals of alleged tax law violations seriously and considers all relevant information on any applicable audit.
The Taxpayer First Act protects employees who report or assist in an investigation regarding underpayment of taxes or any conduct which the employee reasonably believes constitutes a potential violations of tax law or federal law relating to tax fraud.
Because of taxpayer privacy laws, however, the IRS cannot provide information about the status of an audit or investigation.
