River Forest Township Property Taxes

River Forest is one of Cook County’s signature townships. Blessed with a suburban feel while still being close to the heart of the city, River Forest has some of the most in-demand property for both businesses and homes. This demand has seen values from the Cook County Assessor’s Office (CCAO) skyrocket in recent years, putting pressure on those who wish to stay in their homes. Property taxes in Cook County are already the highest in the nation, and that burden is magnified when it comes to River Forest. Thankfully, there are options available to property owners, including exemptions and property tax appeals.

2026 Reassessment

River Forest was ground zero for the infamous 2023 triennial reassessment, which saw many longstanding issues in Cook County finally come home to roost. This is now generally seen as the inflection point that led to outrage over growing taxes and values. This also solidified the fear of the reassessment in the minds of people across Chicagoland. 2026 will see the triennial reassessment once again focus on River Forest and the rest of the south and west suburbs. River Forest is usually one of the first townships in Cook County to be thrown into the fray, and 2026 is no different. Even outside of years without a reassessment, values can still increase thanks to the equalization factor. Tax rates also increase without regard to the year and can lead to extensive spikes annually.

How Homeowners and Businesses in River Forest Can Reduce Values and Taxes

With the one-two combo of high values across Cook County and the demand for real estate, River Forest always faces some of the stiffest taxes in the area. Out-of-control taxes are threats to both people wishing to stay in their homes and those who are looking to buy in the area. With little help coming from the city or state government, the people of Cook County have to be willing to take matters into their own hands. Thankfully, both homeowners and businesses have options to help protect themselves against rising costs.

River Forest Homestead Exemption

Exemptions:

The homestead, senior, disabled person’s, and other exemptions should always be the first option when it comes to reducing tax burden. While the homestead is universal for homeowners, specialized exemptions can help protect the most vulnerable populations from aggressive assessment and taxation.

River Forest Property Tax Appeal

Property Tax Appeals:

Both homes and businesses can challenge their values. Like exemptions, these do not lower taxes directly, but rather, reduce a property’s value from being taxed. By lowering these values, a significant property tax reduction can often be achieved.

Cost Segregation

Cost Segregation:

A technique exclusively for businesses, cost segregation has been supercharged thanks to recent legislation. This takes on federal income taxes instead of property taxes, but can still significantly improve a business’s bottom line. By using accelerated depreciation of real property, businesses can shield some or all of their income from taxes.

Property Tax Appeals Protect Property and Taxpayers

A decade ago, property tax appeals were generally used by businesses and the wealthy. However, following the 2023 reassessment, people from all walks of life began to use this option to question the values assessed by the CCAO. When backed by evidence, a solid appeal can lower the assessed value of a home or business. Appeals can fix basic errors, such as the wrong square footage or classification, and are perfect for fixing blatant errors. They can also challenge property values based on lack of uniformity or based on overassessment. Lack of uniformity is when your property is assessed more than neighboring properties with the same or similar characteristics. Overassessment is when the market value of your property does not match what it would sell for on the open market.

While some issues can be solved easily, it can be difficult to prove errors in value. To prove lack of uniformity, assessments from the area must be gathered, documented, and often photographed. For overassessment, sales of properties dating back three years must be collected. For each type, these comparisons must be close to each other in several ways, including location, size, and classification. Taxpayers do have more time to gather evidence than the rest of Illinois, because they have two appeal deadlines, rather than one. The first deadline is for appeals with the assessor, which is 30 business days after the notice of assessment is sent. The second is with the Board of Review (BOR), which is usually months later.

Frequently Asked Questions About River Forest Property Taxes

All properties in Illinois must be assessed the same. Illinois usually taxes homes at 33.3% of the market value, but Cook County only uses 10%. The equalization factor is applied to bring this back into balance. It is applied before tax rates are set, ensuring that Cook County residents pay the same as everyone else.

Tax rates and the equalization factor change every year, which means taxes can go up even outside of a reassessment. In fact, taxes have increased every year in Cook County for 30 years. Appealing annually keeps these increases from taking hold. Beyond that, appeals can help establish a property’s true value, acting as a building block well into the future.

Yes, with the average market value for a single-family home being around $918,000 according to the CCAO. This is due to River Forest being a high-demand neighborhood with many historic buildings.
