When someone owns property and makes it his or her permanent residence or the permanent residence of his or her dependent, the property owner may be eligible to receive a homestead exemption that would decrease the property's taxable value by as much as $50,000.
While the specifics can vary by state, generally, homestead exemptions are only available for an individual or family's primary residence. This means you cannot claim homestead exemptions in multiple states.
General Homestead Exemption (GHE) (35 ILCS 200/15-175) The amount of exemption is the increase in the current year's equalized assessed value (EAV), above the 1977 EAV, up to a maximum of $10,000 in Cook County, $8,000 in counties contiguous to Cook County, and $6,000 in all other counties.
Benefit: Following the Illinois Property Tax Code, this exemption lowers the equalized assessed value of the property by $8,000.
