Dundee Township Property Taxes

Located on the Fox River, Dundee is a key suburb of Chicago and one of the main townships in Kane County. Rapidly growing like the rest of the area, Dundee has seen impressive population growth in recent decades. With more people fleeing Cook County for the surrounding collar counties, this population will only continue to grow in the coming years. Thanks to rising demand across the area, prices for homes and businesses in Kane County, especially in Dundee, have skyrocketed in the past few years. To compensate, the people of the township are using various methods to secure property tax reductions.

Kane County Reassessment

While reassessment might not carry quite the burden it does in Cook County , the process of evaluating every home and business in the township can significantly increase taxes and property values. Currently, Dundee and the rest of Kane County will see reassessment in 2027. However, taxes can rise outside of reassessment due to increasing tax rates and a fluid equalization factor. In 2025, the total value of homes increased by 10%, while the value of businesses surged by 11%.

Ways to Save on Property Taxes

While property taxes in Illinois are some of the highest in the nation, there are a few ways for taxpayers to legally reduce these costs. Both homeowners and businesses have options that can be deployed to secure reductions, with some rarely being used. Kane County has seen a recent push to get even more reductions for its citizens, and many of these options are being explored in record numbers, with Dundee being one of the leading townships.

Exemptions:

Starting with the homestead exemption, this option is vital to bringing down property taxes. Exemptions are used to reduce the equalized assessed value (EAV), which is one of the primary factors in calculating a property tax bill. There are many options beyond the standard homestead exemption, such as those for veterans, people with disabilities, seniors, and more. Every property owner should aim to get as many exemptions as possible.

Property Tax Appeals:

These are used to challenge the taxable values placed on homes and businesses by assessors. These can help establish the true value of a property, ensuring that it is only taxed at a fair level. These do take evidence and hard work, but can usually secure significant reductions in taxes.

Cost Segregation:

This method is used by businesses to reduce federal income taxes. While it does not impact property taxes, it can be used to entirely eliminate income tax in the first year, and cost segregation studies often pay for themselves over a dozen times in just the initial year. The reduction is achieved thanks to the accelerated depreciation of real assets.

Property Tax Appeals in Dundee Township

Like Cook County and the rest of Illinois, Dundee Township has begun embracing property tax appeals at a level never seen before. This is because tax rates have continued to increase, while property values have also skyrocketed. This trend has been driven in part by residents relocating from Chicago to the suburbs, increasing demand and property values throughout the region. Thanks to an awareness campaign at the end of 2025, the people of the collar counties, including Dundee, have been educated on the use of appeals, which will only encourage more engagement in the future.

Unlike Cook County, the people of Dundee, like the rest of Illinois, only have one chance to appeal their taxes. There is no assessor appeal in Dundee Township; taxpayers can only file a protest with the Board of Review (BOR). This means that the appeal deadline is final, and missing it means losing the chance to challenge taxes for the entire year. In addition, there is no way to retroactively appeal, so missing the deadline essentially allows errors or overassessment to continue for another year.

O’Connor Supports Successful Appeals with Evidence

While awareness was the first obstacle that prevented the filing of appeals in high numbers, the second was the amount of evidence required. Unlike exemptions, appeals need to be backed by extensive evidence to be successful with the BOR. What evidence is required is determined by the grounds of the appeal. If the appeal is based on overassessment, this means that the taxpayer must collect property sales records from the previous three years. For those challenging the lack of uniformity in assessment, they must gather assessments from around their area. In either case, the comparable properties in these records should be of a similar size, age, and location.

O’Connor is here to make this process easier. We have been helping clients for over 50 years and provide premium support when it comes to gathering evidence. We will analyze your assessment for issues and opportunities, then use data-driven techniques to put together evidence. We will also use our advanced and proprietary databases to find the perfect sales records and assessments. Once all of this evidence is gathered and curated, we will engage an expert law firm to coordinate an appeal. There is no cost for this analysis or evidence, and our clients are only charged a contingency fee if their taxes are lowered.
