Estimate: we don't have an exact county/city table for this state yet. The local box starts at the 2.71% statewide average local rate. Illinois local taxes on dealer sales depend on the dealer's location (and Chicago/Cook add their own); private-party sales use a separate flat Private Party Vehicle Use Tax (RUT-50) by price/age. Why still an estimate: the rate follows the seller's location, not yours, so a home-county picker would be wrong.
