Service is Caring……

The Lyons Township Assessor is your nearest liaison to the Cook County Assessor’s Office. Our job is to provide professional help on your real estate assessments and tax bills. Our mission is to efficiently perform the duties relating to property assessments assigned to township assessors by the State of Illinois within the county of Cook, and to thereby effectively serve the residents, property owners, and government of the Township.

If your opinion of the value of your property differs from the Cook County Assessor’s, by all means come in and discuss the matter with us. We will be happy to discuss any questions you may have regarding the assessed value of your property.

The Assessor’s Office provides many services for more than 51,000 real estate parcels including, but not limited to …

  • Filing for  Senior Freeze Exemption, and Senior Homestead Exemption (ages 65 and over).
  • File Homeowners Exemptions, which is available to all homeowners regardless of age, Disabled Homeowners, Disabled Veterans and Returning Veterans Exemptions.
  • Provide the necessary information to determine if your property is being fairly assessed.
  • Verifying exemptions for homeowners.

  • Assistance to homeowner’s and seniors in completing Certificate of Error forms for any exemptions they did not receive, which may result in a refund.

Increased spending is what really makes real estate tax bills go up!

The primary job of the Cook County Assessor is to make sure that every real estate parcel in Cook County is assessed at fair market value. This is a very complex and difficult job. Cook County has approximately 1.8 million real estate parcels and it is reasonable to assume that some mistakes occur.

If you discover that your property is: (1) assessed over market value or if your property is (2) described incorrectly or if your property (3) is not assessed uniformly with similar properties in your neighborhood – we can help!

The Township of Lyons is now collecting used eye glasses, hearing aids, cell phones, and ink cartridges to support the Lions Club. If you would like to make a donation, please feel free to drop off at either the Assessor’s office or the Clerk’s office.
