Libertyville Township Property Taxes

One of the largest townships in Lake County, Libertyville Township encapsulates why the area remains one of the premier suburban areas near Chicago and Cook County. While within commuting distance, Libertyville Township still has the small-town charm that draws more new residents every year. With great schools and other amenities, even more people will flock to the township in the next few years to escape Cook County. This has the unintended effect of driving up the values of homes and businesses, making the already expensive property in Libertyville harder to afford. This has forced residents to explore various ways of lowering these values and Lake County property taxes.

Reassessment Increases Taxes

Like much of Lake County, Libertyville Township has some of the most expensive real estate in Illinois. The taxable value of this property grows every year, thanks to market demand. However, whenever Lake County is reassessed, values truly spike across the township. The next reassessment is scheduled for 2027 and can be expected to have a large impact. Even outside of assessment years, taxes can still increase thanks to rising tax rates and the equalization factor. Like many townships, Libertyville also has to deal with Tax Incremental Financing (TIF), which often allows taxing entities to skirt statewide caps.

Ways to Achieve Tax Reduction

With so much value already at stake, getting a tax reduction in Libertyville Township property taxes is a top priority for homeowners and businesses. While tax rates cannot be challenged or corrected, taxable values can. This starts with market value, which is what the assessor believes a piece of real estate would sell for on the open market. This is then multiplied by the assessment ratio of 33.33%, after which the equalization factor is applied. This creates the equalized assessed value (EAV), which is what tax rates are applied to calculate property tax bills. In order to get a property tax reduction, either the market value or EAV must be cut. There are a few ways to accomplish this.

Libertyville Township Exemption

Exemptions:

Starting with the homestead exemption, these methods achieve tax reduction by lowering EAV. The homestead exemption alone cuts $8,000 in EAV, which can be augmented by other exemptions, such as those for people with disabilities or seniors. Exemptions are easy to obtain, as obtaining them usually requires simply filing an application. Some exemptions have income caps, which prevent those with higher incomes from utilizing certain types.

Libertyville Property tax appeal

Property Tax Appeals:

These are available to every homeowner and business, regardless of property type. These are used to challenge the values placed by the assessor, and can often be used to lower the market value of a home or business, which leads to a lower property tax burden. These can even be used with exemptions to get supercharged savings. Unlike exemptions, appeals are a more difficult technique, requiring evidence and often significant time.

Libertyville Township Benefits Strongly From Appeals

Because of the high property values in Libertyville Township, simple reductions from exemptions may not be enough. This can be especially true for those with income limits, as many families with significant earnings may be outside the exemption threshold. In addition, businesses, rental properties, and other income-generating real estate may not be able to use exemptions at all. Appeals can also correct any valuation issues, such as unfair assessment or inflated market values.

Property tax appeals also have a strict filing deadline. There is only one deadline for Libertyville Township, which is for a protest with the Board of Review (BOR). This is a hearing with an impartial board that reviews the evidence presented by both the taxpayer and the assessor. This means that a taxpayer must file before the deadline, or any unresolved issues will move forward into the next year. This can result in significant tax increases, which cannot be retroactively reversed.

O’Connor Offers Premium Evidence

The hardest part about an appeal is gathering the evidence. In cases where a taxpayer is trying to contest overassessment, they must gather several property sales records dating back three years. For cases of unequal assessment, the taxpayer must gather assessments to demonstrate that their property is being unfairly taxed. In either case, these comparable properties must be similar in location, size, and age. Each comparable property must also tell the story that the taxpayer needs.

We at O’Connor are here to help with every aspect of evidence gathering. We start by analyzing the assessment for any issues that need to be protested. We use valuation analysis to zero in on any anomalies. We then use our proprietary databases to find the best comparable properties possible. Finally, we curate this evidence and coordinate an appeal with a law firm that has experience in property taxes. There is no cost to enroll, and our clients only pay for evidence if their taxes are lowered.
