Property Taxes The state offers a General Homestead Exemption, which applies to owner-occupied residential property. That break can exempt from taxation a maximum of $6,000 ($7,000 in Cook County) from a property's equalized assessed value (EAV).The median property tax on Illinois' median home value of $171,900 is $3,952.Tax breaks for seniors: The Senior Citizens Homestead Exemption allows a $5,000 reduction in the EAV of the property that a person 65 or older is obligated to pay taxes on, and owns and occupies, or leases and occupies as a residence.The Senior Citizens Assessment Freeze Homestead Exemption allows senior citizens who have a total household income of less than $55,000, and who meet certain other qualifications, to maintain the EAV of their homes at the base-year EAV, thereby preventing any increase in that value as a result of inflation.The Homestead Improvement Exemption is limited to the fair cash value that was added to the property by any new improvement, up to an annual maximum of $75,000. The exemption continues for four years from the date the improvement is completed and occupied.The Senior Citizens Real Estate Tax Deferral Program allows people age 65 or older, who have a total household income of less than $55,000 and meet certain other qualifications, to defer up to a maximum of $5,000 of real estate taxes and special assessments. The deferral is similar to a loan against the property's market value, and a lien is filed on the property to ensure repayment of the deferral. The state pays the property taxes and then recovers the money, plus 6% annual interest, when the property is sold or transferred. Inheritance and Estate Taxes There is no inheritance tax. Illinois has an estate tax with a $4 million exemption. The maximum estate-tax rate is 16%.
