How much is the car sales tax rate in Illinois?

The statewide sales tax in Illinois is 6.25% and is applied to any car purchase, regardless of whether it’s new or used. You will also need to take into account the county or local sales tax

How are car trade-ins taxed in Illinois? 

Many dealers will allow you to
trade in an old vehicle
so that you can use the credit towards purchasing a new car. In Illinois, the car sales tax only applies to the final ticket cost of your car, as the value of your trade-in is not subject to taxes. 
For example, you’re buying a
Hyundai Veloster
worth $23,000 in
Chicago
, and you’re trading in your old
Audi A4 Premium
for a $6,500 credit. You’ll only have to pay Cook County’s 11.5% combined state and local sales tax on $16,500 of the purchase. 
However, if you receive dealer rebates and incentives, they are not exempt from sales tax. In other words, the sales tax will still be applied to the full price of the vehicle before dealer incentives.
