About this map

Every property transaction must be recorded at a county recorder of deeds office. These recordings are then submitted to the Illinois Department of Revenue so the department can calculate how much Real Estate Transfer Tax is due to the state, county, and any other jurisdiction that charges RETT (also called stamp duy in some jurisdictions). The data collected includes the buyer's name, the seller's name, and a description of the property, among other details.
