Evanston Township Property Taxes

Formerly closed townships have been reopened for Board of Review appeals with a filing deadline of December 12, 2025.

Evanston is one of Cook County’s most historic areas. Evanston has been one of the most popular townships for nearly a century. With great schools, plenty of amenities, and its close proximity to Chicago, the demand for homes and businesses in Evanston has never been higher. Great infrastructure requires high taxes to operate, and with rising property values, many homeowners in Evanston are feeling squeezed on all sides. Like the rest of Cook County, the people of Evanston have been exploring solutions to high values and taxes in record numbers.

Cook County Property Tax

Reassessment

One reason for such high costs in Evanston is that it went through reassessment in 2025. Thanks to being under the magnifying glass of the Cook County Assessor’s Office (CCAO), the township saw its property values break records. The value of homes climbed by a combined 23% in 2025, while businesses soared by 35%. In addition, homes across Cook County saw their taxes increase by 16% thanks to a downturn in business values in places like the Loop. Even though the township will not have to worry about reassessment until 2028, taxes can still increase thanks to things like tax rates and the equalization factor.

Homeowners and Businesses can Lower Their Values and Taxes

Much of what makes taxes in Cook County is unassailable. Tax rates and the equalization factor cannot be lowered by individual taxpayers. However, this does not mean that the average person is powerless, far from it. There are options that any homeowner or business can explore that help level the playing field against the CCAO. This is because property values are wide open to reductions thanks to certain techniques. By deploying these options, taxpayers are able to exert a modicum of control over their circumstances.

Exemptions: Homeowners can get off to a running start with the homestead exemption, which cuts a significant bit of value from their tax bill. This can be enhanced by other exemptions, such as those for disabled people or those for seniors. Since they are so crucial to protecting homes, every taxpayer should know the exemptions they are qualified for and maximize them to the fullest.

Property Tax Appeals: The values imposed by the CCAO can be challenged through appeals, both for homes and businesses. Lowering these values reduces the amount that equalization and tax rates are applied to, generally leading to a smaller tax bill.

Cost Segregation: Businesses can reduce or eliminate their federal income taxes by utilizing accelerated depreciation of tangible assets. While this does not help with property taxes, it can open up extensive cash flow, especially with the return of 100% bonus depreciation.

Property Tax Appeals are Clutch in Cook County

While they were once mostly the arena of businesses and some elite homes, property tax appeals have quickly taken Illinois and the Chicago area by storm. After many issues with the CCAO and taxing bodies, appeals have come to the forefront. Even the CCAO now encourages every taxpayer who can to appeal their taxes. First, this helps taxpayers by ensuring that all of the data on their property is correct. This includes things like exemptions, owner’s name, size, and classification of a property. Any errors in this important data can lead to much higher taxes.

Once the data is confirmed, the values should be examined. While taxes are high, that is not grounds alone for an appeal. Instead, a taxpayer needs to focus on issues of overassessment or lack of uniformity. By having solid grounds for appeal, along with key evidence, a taxpayer has the best possible chance to land a reduction. Appeals have become so vital for the financial health of property owners in Cook County that many government organizations recommend using them every year.


Deadlines to Keep in Mind

Because deadlines are so important, it is best for a taxpayer to always keep them in mind. When it comes to tax reduction, it is best to know when the final days for exemptions and appeals are. Unlike the rest of Illinois, Cook County residents have two appeal deadlines instead of one. The first deadline is an appeal directly to the CCAO. The deadline for this is 30 business days after the notice of assessment is mailed. The second is a formal appeal with the Board of Review (BOR), which is later in the year, usually several months away. Missing an appeal deadline or the chance to get an exemption can cost a taxpayer thousands of dollars.

  • Due date for the first installment of property taxes: April 1, 2026
  • Notices of assessment mailed out: April 22, 2026
  • Final day to file exemptions: May 15
  • Final day for an assessor’s appeal: June 4, 2026
  • Board of Review deadline: pending
  • Second installment of property taxes due date: pending

O’Connor Assists with Evidence and Analysis

In order to get a reduction in an appeal, evidence is required. If you are challenging on the basis of overappraisal, you will need to decide if you want to challenge on the grounds of lack of uniformity or overassessment. Overassessment is when the value of a home or business is much higher than what it would sell for on the open market. This can usually be proven by showing multiple sales records for similar properties dating back over three years. Lack of uniformity is when a property is assessed at a much higher rate than similar neighboring properties. This is proven by using several assessments that demonstrate the disparity.

Collecting these records and analyzing this data can feel like a second job. We at O’Connor are here to help. For over 50 years, we have been helping clients by providing in-depth analysis of appraisals and by gathering the right evidence to help their appeal cases. We use our state-of-the-art databases and data-driven techniques to gather the perfect evidence to back your protest. When we have the evidence, we then coordinate an appeal with a specialist law firm. Backed by our evidence, you and your attorney will have the best shot at winning your case. You will pay nothing for this evidence, unless you and your attorney can lower your taxes.
