The Compliance and Investigation Bureau is responsible for creating and maintaining a climate of voluntary compliance with applicable state laws by investigating complaints relating to fraudulent activities involving motor vehicle sales tax, titling and registration, odometer, driver’s license, license plates, cigarette tax and diesel fuel tax. The Bureau ensures compliance with licensing regulations for motor vehicle dealers, marine dealers and salvage businesses. Bureau investigations develop information on violations that often lead to business licensure discipline and the prosecution of individuals or businesses. To ensure confidence and trust in the Department of Revenue, the Compliance and Investigation Bureau also conducts internal audits and investigations within the Department of Revenue and motor vehicle fee offices.

The Compliance and Investigation Bureau serves the entire state of Missouri, with offices in Jefferson City, Cape Girardeau, St. Louis, Kansas City, and Springfield.
