Free Illinois Free Printable Bill of Sale
The Secretary of State's title requirements do not call for a specific bill of sale form, so a clearly written printed bill of sale serves as your record — but Illinois also requires buyers to submit Form RUT-50 (Private Party Vehicle Use Tax Transaction) at the same time as the title transfer. The buyer applies for title at an Illinois Secretary of State facility within 20 days after the vehicle and the signed title are delivered, and the RUT-50 is due within 30 days of purchase. The SOS title checklist does not list a bill of sale, but it is a useful record, and the Illinois title does not need to be notarized.

Illinois Free Printable Bill of Sale — What You Need to Know
Sales Tax Details
Illinois charges a private party vehicle use tax, collected via Form RUT-50 at the time of title transfer. The amount is set by model year when the price is under $15,000, or by price at $15,000 or more.
Exemption: Check the RUT-50 instructions for how family transfers are treated.
Inspection Requirements
Illinois does not have a statewide mandatory vehicle safety inspection. However, vehicles registered in the Chicago area (Cook, DuPage, Kane, Lake, McHenry, and Will counties) must pass an emissions test (IDES) before registration or renewal in most cases.
Illinois Free Printable Sale — Step-by-Step Checklist
- Draft a printed bill of sale with the full vehicle description (year, make, model, VIN, color, odometer)
- Include the full legal names, addresses, and signatures of both buyer and seller
- State the agreed sale price and the exact date of the sale
- Obtain and complete Form RUT-50 (Private Party Vehicle Use Tax Transaction) — this is mandatory
- Have the seller sign the back of the Illinois title, completing the odometer disclosure section
- Check whether the vehicle requires a Chicago-area emissions test before registration
- Bring the signed title, completed RUT-50, proof of insurance, and payment to an IL SOS facility (keep the bill of sale as your record)
- Apply for title within 20 days after the vehicle and the signed title are delivered
Common Pitfalls
- Forgetting Form RUT-50: This is the most common and costly mistake in Illinois. The RUT-50 is not optional — it is a mandatory tax form that must accompany every private vehicle sale title transfer. Without it, the SOS will not process the transaction.
- Missing the deadlines: the title application is due within 20 days after the vehicle and the signed title are delivered, and the RUT-50 within 30 days of purchase — late filing can add fees.
- Skipping the emissions test: Vehicles registered in the six-county Chicago metro area typically require an IDES emissions test. Attempting to register without a passing emissions certificate will result in rejection at the SOS office.
- Incomplete title assignment: The seller must fully complete the title assignment on the back of the certificate, including the odometer reading. An incomplete title cannot be processed and will require a court order or additional documentation to fix.
- Undervaluing the sale price on RUT-50: once the price reaches $15,000 the tax is set by the price, so an understated figure misreports the tax owed.
Pro Tip
Illinois's paperwork — the signed title and title application plus the mandatory RUT-50 tax form — is what catches most out-of-state buyers off guard. Prepare everything before visiting the Secretary of State, double-check the Chicago-area emissions requirement, and apply for title within the 20-day window.
