How can you obtain Illinois property tax information?

Property tax in Illinois is administered by local governments and taxing districts, according to the Illinois Department of Revenue. IDOR maintains a database of local government contact information, listed by county, on its website.

Most Illinois counties now provide property tax information online, but there are some locations where you may still have to contact the local assessment office, which is shown on the IDOR website, in person. The largest Illinois county, Cook County, which includes the city of Chicago, provides extensive information on its Property Tax Portal. You can search for individual property information by PIN number or by street address. Property tax histories are available for each property, as well as general information on tax exemptions and the appeals process, according to its website.
