How property tax works in Illinois
Illinois property taxes are set locally: your county or city multiplies your home’s assessed value by a millage rate to produce the bill. Expressed as an effective rate — tax as a share of market value — Illinois sits at about 2.08%, on the higher end nationally. Because rates and assessments differ by jurisdiction, two homes of equal value in different counties can owe different amounts.
Lenders typically collect property tax monthly in escrow and pay it for you, so it’s built into your mortgage payment. To estimate yours, enter your home value and your county’s rate in the calculator above.
