ST. PAUL — A new state report says some drivers in Minnesota were overcharged for vehicle licensing transactions because of the troubled licensing and registration system.

The review released Tuesday by the Legislative Auditor says its investigators found “significant inaccuracies” in some transactions through the Minnesota Licensing and Registration System known as MNLARS, including those for newly registered passenger vehicles and heavy non-passenger vehicles.

The Star Tribune says the report indicates some owners of similar vehicles were charged different tax amounts.

Minnesota IT Services and the Minnesota Department of Public Safety said the agencies are committed to enhancing MNLARS, but noted “the vast majority of inaccuracies” were not the result of a malfunctioning IT system.

Republican state Representative Paul Torkelson of Hanska, who chairs the House Transportation Finance Committee, says the system must be fixed.
