How it works

Illinois taxes the price after the trade-in allowance. On a $35,000 car with a $10,000 trade-in, tax applies to $25,000 — about $1,563 instead of the $2,188 you'd owe with no trade. Sales or use tax is collected when the vehicle is titled and registered.

Illinois has the second-highest effective property tax rate in the country, so even with modest home prices the annual tax bill is large — often the biggest single line in the monthly payment outside principal and interest. Local add-on tax rates and documentation fees vary by dealer and county, so treat the preset rate as a starting point and confirm the exact figure on your paperwork.
