How to Sell a Car Privately in Illinois (2026 Guide)
Quick Answer
To sell a car privately in Illinois you need: a signed title, a completed bill of sale (VIN, sale price, odometer, date, both signatures), and photo ID. The buyer has 20 days to transfer the title at the Illinois Secretary of State and pay the $150 transfer fee plus pass an emissions test.
Illinois-Specific Note
Illinois title and registration is handled by the Secretary of State (not a DMV). Buyers must file form RUT-50 (Private Vehicle Use Tax Return) and pay use tax within 30 days of purchase. Chicago and surrounding counties have additional local taxes.
Step-by-Step: How to Sell a Car Privately in Illinois
Follow these 7 steps in order. Do not skip step 6 — a missing or incorrect bill of sale is the #1 reason title transfers are rejected by the Illinois Secretary of State.
- 1Price your vehicle using Kelley Blue Book (kbb.com) and Edmunds (edmunds.com) to establish fair market value. Cross-reference at least two sources. Set your asking price 5–10% above your walk-away number to leave negotiating room.
- 2Gather your documents before advertising: the clear title (no open liens), valid government-issued photo ID, maintenance records, and any warranty paperwork. If there is an open lien, contact your lender to arrange a payoff and lien release before listing.
- 3Run a VIN history report and share it with prospective buyers. Reports from Carfax or AutoCheck cost around $40 and show accident history, odometer records, and title status. Serious buyers expect this — having it ready prevents the "I need to check the VIN" negotiating tactic.
- 4Photograph and list the vehicle with full details: mileage, options, maintenance history, and known condition. State "as-is, private sale" clearly in the listing. Use at least 10 photos taken in daylight from multiple angles.
- 5Screen buyers: allow test drives only after requesting a valid license. Meet in a public location (a bank parking lot is ideal — you can accept a cashier's check on the spot). Never allow an unsupervised test drive.
- 6Complete a Illinois bill of sale at the time of the sale. Both buyer and seller must sign. The document must include the VIN, sale price, odometer reading, sale date, and full names and addresses of both parties.
- 7Sign over the title to the buyer. The seller signs the assignment section on the back of the title. Double-check every field — an incorrect title is rejected by the Illinois Secretary of State. The buyer has 20 days to complete the title transfer.
Required Paperwork for a Illinois Private Car Sale
Signed vehicle title
The seller signs the back of the Illinois title in the assignment section. Fill in the buyer's full legal name, sale price, and date. Do not leave any field blank.
Bill of sale
Must include: buyer and seller full names and addresses, VIN (17 characters), year, make, model, odometer reading in miles, sale price (written and numeric), sale date, and both parties' signatures.
Odometer disclosure
Required by federal law (Truth in Mileage Act) for vehicles under 10 model years old. Illinois also requires odometer disclosure under state law. Record the exact odometer reading at the time of sale.
Government-issued photo ID
Both parties should bring a valid driver's license or state-issued ID. This confirms identity and reduces fraud risk. Make a photocopy for your records.
Emissions / smog certificate
Illinois requires annual emissions testing for vehicles 4+ model years old in Chicagoland (Cook, DuPage, Kane, Lake, McHenry, and Will counties) and Metro-East St. Louis (Madison and St. Clair counties). Cost is $20.

Protect Yourself After the Sale
Signing over the title and handing over the keys does not automatically end your liability in Illinois. If the buyer is involved in an accident, receives a traffic citation, or accumulates unpaid tolls before transferring the title, you may receive notices — or worse, have your license suspended.
Notify the Illinois Secretary of State of the sale by completing the "notice of sale" on the back of the title. This protects you from liability for the vehicle after the sale date.
3 Common Mistakes When Selling a Car in Illinois
Forgetting form RUT-50 — this Illinois-specific form is required for all private party vehicle purchases. Without it, the buyer cannot transfer the title.
Missing the 20-day transfer deadline — Illinois requires title transfer within 20 days of the sale date. Late transfers incur escalating fees.
Skipping emissions testing — Illinois requires testing in the Chicago metro (Chicagoland) and Metro-East St. Louis areas. Vehicles over 4 model years old in these areas cannot be re-registered without a current emissions certificate.
Frequently Asked Questions
What paperwork do I need to sell a car privately in Illinois?▾
To sell a car privately in Illinois, you need: (1) the vehicle title signed and dated by the seller; (2) a completed bill of sale with VIN, sale price, odometer reading, sale date, and both parties' signatures; (3) valid government-issued photo ID; and (4) an odometer disclosure statement for vehicles under 10 model years old. A VIN history report, while not required, is strongly recommended to reassure buyers and justify your asking price.
How long does the buyer have to transfer the title in Illinois?▾
In Illinois, the buyer has 20 days from the date of sale to transfer the title at the Illinois Secretary of State. Missing this deadline results in late fees. Sellers should file a notice of sale with the Illinois Secretary of State promptly after the sale to avoid liability for post-sale incidents.
Does Illinois require a notary for a private car sale?▾
No — Illinois does not require notarization for a standard private car sale. Both parties simply need to sign the bill of sale and the seller signs the back of the title. Voluntary notarization is always an option for extra legal protection, particularly for high-value vehicles.
How much is the title transfer fee in Illinois?▾
The title transfer fee in Illinois is $150. This fee is paid by the buyer at the Illinois Secretary of State at the time of registration. In addition to the title fee, the buyer pays Illinois charges 6.25% state use tax on private vehicle sales, plus local taxes of 1–4%. Private party purchasers must file form RUT-50 and pay use tax at a Secretary of State facility. Registration fees are also due at that time.
Can I sell a car without a title in Illinois?▾
Selling a vehicle without a clear title in Illinois is strongly discouraged and may be illegal. If you have lost the title, apply for a duplicate title at the Illinois Secretary of State before listing the vehicle. If you have an outstanding loan, contact your lender to arrange a payoff and lien release. Buyers who purchase a vehicle without a proper title will have serious difficulty registering it.
