Illinois car sales tax rules

- Rate used in the calculator: 8.98% (state 6.25% plus the average local rate; up to 11% in some areas)
- Local taxes: Local taxes apply based on the dealer’s location, and home-rule use taxes (such as Chicago’s) based on where you register.
- Trade-in credit: Yes, on dealer sales. Private-party sales use a separate flat tax and get no trade-in credit.
