The sale of a vehicle by an authorized personal representative, receiver, trustee, sheriff, or other representative or successor must also be reported.
Missouri licensed dealers who do not file their sales reports electronically must complete a Notice of Sale (DOR-5049Adobe Acrobat PDF or DOR-5049A) for each retail sale made to a Missouri resident. Click here for dealer reporting requirements.Adobe Acrobat PDF
