Lemont Township Property Tax

Lemont Township is nestled about an hour outside of the city of Chicago, in Cook County. Offering the charm of a small town, the streets are lined with limestone buildings and unique local shops. This suburb is also known for its walkability and outdoor recreation. In contrast to these perks, Lemont Township continues to face rising property values and Cook County property taxes, along with the rest of Cook County.

Lemont Township Reassessment 

In 2026, the southern and western suburbs of Cook County will undergo their triennial reassessment. During this process, the Cook County Assessor’s Office (CCAO) reassesses every home and business within a third of the county. Now that Lemont is being reassessed again, property owners should take a close look at their new property values and characteristics. The CCAO released 2026 reassessment notices in August, with the new values affecting the second installment of property tax bills issued in 2027.

Resources to Reduce Property Taxes

Homeowners and businesses cannot control tax rates or the equalization factor. However, a reduction in property taxes can lead to a smaller tax bill. There are many techniques to achieve lower property taxes. Due to past mistakes, the use of these methods is being supported by the CCAO, the Cook County Treasurer, and other members of local government.

Bremen Homestead Exemption

Exemptions:

Property tax exemptions are often one of the quickest ways to reduce your property tax bill. The CCAO offers many exemptions, and homeowners should take advantage of every exemption for which they qualify. The standard Homeowner Exemption alone can reduce your equalized assessed value (EAV) by $10,000. Additional exemptions may be available for homeowners with disabilities, many veterans, and qualifying seniors. These exemptions can lead to significant savings, and simply filing is all that is required.

Property Tax Appeals:

A property tax appeal challenges an assessment when a property’s value may be recorded as higher than what is accurate. By successfully reducing an inflated assessed value, property owners may be able to lower property taxes. Appeals can be used alongside exemptions to potentially increase overall savings. Unlike with an exemption, more work is required than simply filing. While appeals require more effort, more property owners are filing appeals as taxes continue to increase.

Cost Segregation:

This method can help businesses reduce their federal income tax liability by accelerating depreciation deductions on qualifying assets. If a business can successfully identify and reclassify certain tangible assets, it may be possible to increase deductions and improve cash flow. For eligible businesses, this provides some relief and significant federal income tax savings.

Level the Playing Field on Your Property Taxes

Property tax appeals are based on specific grounds that require evidence to be successful. Two grounds are overassessment and lack of uniformity. Overassessment occurs when a property’s assessed market value is higher than what it would reasonably sell for. This can be demonstrated by gathering sales records from the previous three years. Supporting evidence is focused on assessments for similar properties within the same location.

Cook County taxpayers have two opportunities to appeal their property tax assessments, while taxpayers throughout the rest of Illinois generally have one. The first opportunity is an appeal with the CCAO, where taxpayers can challenge their assessment directly. Several months later, taxpayers have a second opportunity to appeal through the Cook County Board of Review (BOR). With the right evidence and a well-supported case, either appeal may result in significant tax savings. It is important for taxpayers to keep key deadlines in mind. The deadline for filing an assessor appeal is 30 business days after the reassessment notice is mailed.
