Free Illinois Vehicle Bill of Sale
Illinois vehicle sales run through the Illinois Secretary of State (Vehicle Services Department), not a DMV. The buyer must title and register within 20 days using Form VSD 190, and pay the unique RUT-50 flat private-party use tax — a dollar amount tied to the vehicle's age, not a percentage of price. A written bill of sale is not state-mandated but is essential evidence of the transfer date, price, and as-is condition. If the vehicle will be registered in one of the 8 emissions counties (Cook, DuPage, Kane, Lake, McHenry, Will, Madison, St. Clair), confirm the Air Team test status before money changes hands.

Illinois Vehicle Bill of Sale — What You Need to Know
Sales Tax Details
Illinois is the unicorn: private-party vehicle sales are NOT taxed at a percentage. Instead, RUT-50 (Private Party Vehicle Use Tax) charges a flat dollar amount based on the vehicle's model year (age) — generally $25 for vehicles 11+ years old, climbing through a tiered table to roughly $390 for newer vehicles, with a separate higher table for vehicles with a purchase price of $15,000 or more (up to roughly $1,500). This means a $40,000 used Tahoe and a $4,000 beater of the same year can owe nearly identical tax. Pay RUT-50 to the Illinois SOS at title transfer.
Exemption: RUT-50 family rate of $15 applies when the transfer is between spouse, parent, child, grandparent, grandchild, brother, or sister. Gifts (no consideration) and inheritances also qualify for the $15 rate. You must check the family/gift box on RUT-50 and identify the relationship.
Inspection Requirements
Illinois has NO statewide safety inspection. However, vehicles registered in Cook, DuPage, Kane, Lake, McHenry, Will, Madison, or St. Clair counties must pass a biennial Illinois Air Team emissions test (vehicles model year 1996 and newer, gas-powered, generally 4+ years old). Failing emissions blocks registration renewal. Buyers in those 8 counties should confirm the seller's last test pass before purchase.
Illinois Vehicle Sale — Step-by-Step Checklist
- Seller signs the Illinois title in the assignment section, prints the buyer's name, and enters the exact odometer reading and date
- Buyer and seller complete Form VSD 190 (Application for Vehicle Transaction(s))
- Complete Form RUT-50 — check family/gift box for $15 rate if eligible (spouse, parent, child, grandparent, grandchild, sibling)
- Bill of sale lists VIN, year/make/model, sale price, date, and "sold as-is" language signed by both parties
- Buyer brings title, VSD 190, RUT-50, payment, and proof of insurance to a SOS facility within 20 days
- In Cook, DuPage, Kane, Lake, McHenry, Will, Madison, or St. Clair counties, verify the vehicle has a current Air Team emissions pass before registering
- Seller removes plates (Illinois plates stay with the seller, not the vehicle) and reports the sale to SOS
Common Pitfalls
- Assuming Illinois charges a percentage sales tax — RUT-50 is a flat dollar table based on model year, so an old high-value vehicle can owe far less than buyers from other states expect
- Missing the 20-day title transfer deadline — late filing triggers penalties added on top of RUT-50
- Leaving the plates on the car at sale — Illinois plates belong to the seller and must be removed and either transferred to a replacement vehicle or surrendered
- Forgetting RUT-50 entirely and only filing VSD 190 — SOS will reject the title application
- Buying a Cook/collar-county vehicle without confirming emissions — a failed Air Team test blocks registration until repairs are made
- Claiming the $15 family rate for an in-law, niece, nephew, or cousin — RUT-50 limits family to spouse, parent, child, grandparent, grandchild, and sibling only
Pro Tip
For Illinois vehicle sales, file VSD 190 plus RUT-50 with the Secretary of State within 20 days, expect a flat age-based tax (not a percentage), and confirm Air Team emissions if the buyer is in one of the 8 emissions counties.
