How Chicago Property Tax Works

Chicago Property Tax bills come from a multi-step process that starts with your property’s assessed value. The Cook County Assessor’s Office sets the value of every property in the county once every three years for residential homes. Local tax rates from schools, parks, and city services get added to that value to create your final bill.

• Change in your property’s assessed value
• Change in local tax rates from overlapping districts
• Change in the exemptions you qualify for each year

Illinois Tax Caps

The Illinois Property Tax Code uses tax caps to keep bill increases in check each year. The cap limits how much your bill can rise, no matter how your assessed value changes. The Cook County Treasurer’s Office then collects the bill in two equal installments.

Cook County Property Tax Rates by Property Type

Cook County Property Tax rates change each year based on the budgets of local taxing bodies. Chicago sits in a high-demand area, so rates tend to run higher than the state average. The rate you pay depends on your specific location and which school district, park district, and city services cover your address.

Factors That Change Your Rate

Your actual bill may shift outside these ranges based on the specific tax levies from your school district, library, and other local agencies. New debt issued by a school district can raise rates for nearby homeowners. Watch your local levy notices each year to spot rate changes before the bill arrives.

Reading Your Property Tax Bill

Your Chicago Property Tax bill shows several line items that can look confusing at first glance. Each line tells you how much of your total tax goes to a specific local agency. Breaking the bill down helps you see where your money goes each year.

• Taxing agency name (school district, city, library, and so on)
• Tax rate for that agency
• Amount of tax owed to that agency
• Total bill after all agencies are added
• First installment amount and due date
• Second installment amount and due date

• Records of major repairs or unfinished construction

Chicago School District Tax Levy

• Operating costs for teachers, staff, and supplies
• Building maintenance and capital projects
• Special education programs and student services
• Pension payments for retired school employees

How Levies Affect Homeowners

When the school district raises its levy, your share of the tax bill goes up the next year. A small levy increase can mean hundreds of dollars more in tax for the average homeowner. Watch the school board meeting notes each year to spot levy changes early.

Mortgage and Property Tax Chicago

Mortgage and property tax Chicago homeowners pay often go hand in hand through escrow accounts. Most lenders require an escrow account that sets aside money for property tax each month. The lender pays your tax bill from the escrow when the due date arrives, so you never miss a payment.
