West Chicago Township Property Taxes

As part of the Windy City itself, the township of West Chicago exists primarily for the purposes of assessment. Property taxes in Cook County, West Chicago are among the highest in the nation, thanks to issues such as pension problems, tax incremental financing (TIF), and constantly rising values and taxes. Like the rest of the city, West Chicago has seen an increased use of various techniques that are capable of lowering taxes. While some, like exemptions, are standard for every taxpayer, more and more are exploring other options.

Impacts from the Reassessment Cycle

Cook County utilizes a triennial reassessment cycle, which means that one-third of the county is assessed every three years. West Chicago was last reassessed in 2024 and saw some of the largest increases within the city. The market value for homes surged 21%, while businesses added an astounding 34% to their overall value. While the focus is always on reassessment, taxes can still increase in other years, thanks to tax rates, the equalization factor, and demand from government organizations like school districts.

Options in West Chicago to Reduce Property Taxes

There is no way for residents of West Chicago to lower their tax rates or reduce their equalization factor. Instead, property tax reduction methods are focused on the value of property. By lowering taxable value, owners can see large savings on their tax bills. All taxes in Illinois are based on the equalized assessed value (EAV), which is calculated by taking the market value of a property, applying the assessment ratio, and then the equalization factor. In Cook County, 10% of a home’s value is used for assessment, while businesses are assessed at 25%. This makes targeting taxable value paramount for savings. There are a few options when it comes to lowering these values.

Exemptions:

Exemptions work by lowering the EAV of a property. The most notable is the homeowner’s exemption, which works as a standard homestead exemption. This lowers the EAV of a home by $10,000. There are many other types of exemptions that can be used to lower property taxes, including those for veterans, the disabled, seniors, and more. Exemptions are always the first option that taxpayers should explore.

Property Tax Appeals:

Typically used alongside exemptions, appeals target the values of properties directly. This allows taxpayers to correct issues caused by the Cook County Assessor’s Office, such as unequal assessment or overassessed values. While they require evidence to be successful, appeals are key to combating incorrect values and can result in significant tax savings.

Tax Appeals Help the People of West Chicago Fight Soaring Costs

Property tax appeals do not just supplement exemptions; they also grant tax relief for properties that do not qualify for them. Rental homes, many businesses, and second homes all have little or no support from exemptions. Appeals can lower the taxable value of these properties, acting as a form of relief. While appeals used to be used primarily by businesses, homeowners have become an increasingly large share of appeals and have set records for the number of appeals since 2024. The use of appeals is now encouraged by the CCAO, the Cook County Treasurer, and other government agencies. In 2025, an information campaign about appeals was launched to help homeowners and businesses know their rights.

Taxpayers in West Chicago and the rest of Cook County have options that no other residents of Illinois have. While most of Illinois has a single appeal deadline, the people of Cook County have multiple chances. This starts with appeals directly to the CCAO itself. These assessor protests are the first opportunity to get a reduction and are exclusive to Cook County. If the assessor appeal is unsuccessful or missed, the taxpayer can make a traditional protest to the Board of Review (BOR). While assessor appeals are usually scheduled for the summer, BOR hearings are typically held in late fall. While the assessor appeal stage is optional, the BOR stage is not, and missing that date will mean that the taxpayer forfeits their right to protest.

O’Connor Supports the People of Chicago with Evidence

While appeals are important, they do need significant evidence to be successful. While it would be nice to simply ask for a reduction on taxes, taxpayers need to establish grounds for their appeals and provide evidence of why a reduction should be granted. Often, the main grounds are because of overassessment, where a taxpayer’s home or business is being assessed for more than it is worth. To prove this, a taxpayer must present sales records dating back three years that show what similar properties have sold for. For incidents of unequal assessment, when comparable properties are assessed at higher values than neighboring properties, taxpayers must collect assessments from their neighborhood. In either case, these comparable examples must have similar sizes, room counts, and ages to those of the taxpayer’s property.

O’Connor helps the people of West Chicago and Cook County by providing the evidence needed. When clients sign up with us, we use data-driven techniques to study the assessment for issues. Next, we use proprietary databases and techniques to gather the exact evidence needed, typically sales records or assessments. Once all of the crucial analysis and data are gathered, we coordinate an appeal with an expert law firm. We do not charge for this analysis and evidence, and we only ask for a portion of the tax savings if the taxes of our clients are lowered.
