Illinois Bill of Sale Requirements & Free Form

Illinois requirements

• The assigned certificate of title, not the bill of sale, transfers ownership; a bill of sale is a recommended record of the price, parties, and vehicle details.
• Buyers in a private party sale must file Illinois tax Form RUT-50 (Private Party Vehicle Use Tax Transaction) within 30 days of the purchase, per the Illinois Department of Revenue.
• Title and registration are handled by Illinois Secretary of State Vehicle Services; apply promptly after the sale and confirm current deadlines and fees with that office.
• Illinois does not publish a mandatory statewide bill of sale form for ordinary private sales; PDFRaw's general bill of sale can serve as the written record.
• Complete the odometer disclosure on the title assignment where required when transferring a motor vehicle.
• The Illinois sources consulted do not require a notarized bill of sale for a private sale; confirm any document questions with Illinois Secretary of State Vehicle Services.
