How Does the Cook County Property Tax Calculator Work?
Use this Cook County property tax calculator to estimate your annual tax bill. Enter your property's assessed value and our calculator applies Cook County's median effective tax rate of 2.14% — drawn from real transactions across the county — to generate your estimate.
Enter your property's estimated assessed value — the value the assessor assigns to your property, typically lower than market value after exemptions. Our calculator uses the median effective rate (actual bills divided by market value), which accounts for typical exemptions and is more accurate than applying the statutory millage rate directly.
Note: your assessed value reflects any exemptions you currently have. Rates vary across Cook County — scroll down to explore city-level trends and find the rate specific to your area.
Cook County's median property tax bill is $5,588, which is higher than the national median property tax bill of $2,400 and the Illinois median property tax bill of $2,400 by $3,188. If your estimate is higher than expected, Ownwell can protest your Cook County assessment.

Property Tax Bills Across Cook County, Illinois
Property tax bills in Cook County are based on the assessed value of a home, not its market price alone. Local taxing authorities set tax rates, and the bill is calculated by applying those rates to the assessed value after any exemptions are considered. That means two homeowners with similar homes can still owe very different amounts depending on location, neighborhood tax rates, and whether they qualify for exemptions.
For Cook County homeowners, the impact can be significant. The median home price is $248,820, and property tax bills range widely, with the 25th percentile at $2,954 and the 75th percentile at $8,435. At the high end, the 90th percentile reaches $12,450, while the highest median tax bill in Kenilworth is $29,928. By comparison, the national median property tax bill is $2,400.
Ownwell helps homeowners lower their property tax bills by reviewing assessments, identifying potential savings, and filing appeals when a home is overassessed.

Property Tax Appeals in Illinois
Cook County homeowners can appeal their property tax assessments if they believe the assessed value does not reflect the market value of their property. The process begins with a review of the assessment notice and a comparison of the property’s valuation with similar homes nearby. If the assessment appears too high, homeowners may file a protest with the Assessor’s Office and provide evidence such as recent sales, photos, repair estimates, or other records that support a lower value.
What does the appeal process involve? It usually requires submitting a formal complaint within the filing window, along with documentation that shows why the assessment should be reduced. The appeal is then reviewed by the board that listens to the appeals, which considers the facts and decides whether the assessment should stay the same or be adjusted. Homeowners may also be asked to attend a hearing or respond to questions about the property.
What are the possible outcomes? The board may lower the assessed value, leave it unchanged, or, in some cases, increase it if the evidence supports a higher value. A successful appeal can reduce the property tax bill, while an unsuccessful one means the original assessment remains in place.
How can Ownwell help? Ownwell can guide homeowners through the appeal process, help identify whether an assessment is worth challenging, and prepare a strong case with the right supporting evidence. By handling the details and deadlines, Ownwell makes it easier for homeowners to pursue a fair assessment and potentially lower their property taxes.
Exemptions in Illinois
What property tax exemptions are available in Cook County, Illinois?
Cook County homeowners may qualify for several property tax exemptions that can reduce the assessed value of their home and lower their tax bill. The most important is the Homeowner Exemption, which is available for a primary residence and is designed for owner-occupied homes. This exemption is especially valuable because it directly supports homeowners living in the property as their main home.
Other exemptions may be available depending on a homeowner’s situation, including the Senior Citizen Exemption, Senior Freeze Exemption, Disabled Persons Exemption, Disabled Veterans Exemption, Returning Veterans Exemption, and the Longtime Homeowner Exemption. Each program has its own eligibility rules, and some are based on age, disability status, military service, or how long the property has been owned and occupied.
How do homeowners apply for property tax exemptions in Cook County?
Homeowners typically apply through the Cook County Assessor’s Office, and many exemptions require proof that the property is the applicant’s primary residence. Some exemptions may be renewed automatically, while others require a new application or supporting documents. Because exemption rules can vary, it is important to review each program carefully and apply on time.

Ownwell helps homeowners identify every exemption they may qualify for, prepare the application, and avoid missing opportunities to save on property taxes.
