Worked Out-the-Door Price Example (Illinois)

Purchase Scenario: Buying a $32,000 vehicle in Illinois with an $8,000 trade-in allowance and $3,000 cash down payment, using the 6.25% state rate and 2.50% local surcharge (8.75% combined).

Calculation: Taxable purchase base = $32,000 - $8,000 = $24,000. Combined Illinois sales tax = Math.round($24,000 × 0.0875) = $2,100. Trade-in tax savings = Math.round($8,000 × 0.0875) = $700. DMV title fee ($155) + standard passenger plate registration ($151) = $306. Dealer doc fee = $358 (statutory cap). Total Out-the-Door Price = $32,000 + $2,100 + $306 + $358 = $34,764. Total balance to finance = $34,764 - $8,000 - $3,000 = $23,764.

What the Result Means: Because Illinois eliminated the $10,000 trade-in credit ceiling, your entire $8,000 trade is exempt from state and local sales tax, yielding $700 in direct tax savings. Total government fees and capped doc fees add $664 to the transaction.

Illinois Car Buying FAQs

How are Illinois dealer documentation fees regulated?

Illinois statutes strictly regulate dealer doc fees under 815 ILCS 710/13, indexing the maximum legal limit annually to changes in the Consumer Price Index.

Do Chicago and Cook County assess additional vehicle taxes?

Yes. Cook County and the City of Chicago levy municipal sales tax surcharges that can push aggregate vehicle sales tax rates above 9.5%.
