Let’s be honest, taxes can be confusing – especially property taxes! Whether you’re moving to Illinois from another state, buying your first house in the area,  or are just wanting to understand more about property taxes in Cook County, you’ve come to the right place. We’ve created a complete guide to the Cook County property taxes. We’ll answer everything about how they’re calculated, what they pay for, how to pay them, the Cook County property tax portal, and so much more. 

Cook County Property Taxes

Let’s start off by defining what a property tax actually is. To put it simply, a property tax is an ad valorem tax (a tax whose amount is based on the value of the property) that is paid by an individual (or entity) on an owned property (a.k.a. you!). 

How did property taxes come to be? Property taxes actually started all the way back in 1797 when the government needed funding for the U.S. Navy. Back then, taxes were started as a response to needing to finance the wars. However, the modern property tax that we know today was implemented in 1916. Instead of wars, nowadays, property taxes are used to fund government initiatives and services, things such as fire and police protection, libraries, schools, and road work. This is why it makes sense that neighborhoods with higher property taxes tend to have good school districts, safe neighborhoods, and plenty of neighborhood amenities that only homeowners in that neighborhood or county can enjoy. 

No one wants to pay high property taxes, but sometimes higher property taxes mean you’re getting better amenities and services.

Now let’s break down the property tax system step by step:

First, the assessor will assess all real estate located throughout the county and establish a fair market value for each property. Then, the appeals are accepted and decisions are made about changes or exemptions to reduce property taxes. Next, the clerk will determine the tax rates based on the levy ordinances passed by taxing agencies (the agencies who receive a portion of all property taxes paid). They will apply the rate to the assessments received from the assessor to determine the amount of property tax owed. Finally, the treasurer mails out property tax bills and will collect the money. The treasurer takes these funds and divides up money to send it to each entity.

As you just read, there are three main agencies in charge of property taxes: the assessor, the tax collector, and the treasurer. Let’s break down these roles. 

Cook County Property Tax Assessor 

The assessor determines the value of the physical home (or other property) and the land it sits on. They’re basically estimating the market value for all of the owned property. In order to do this, the assessor takes into account the value of the home, the land, and other personal property (think things like cars and boats). They will also work with local authorities to look at local property values.

There are four office locations where you can schedule an appointment to talk with an assessor. To set up an appointment, click here.

Cook County Clerk’s Office 

Now let’s get into the clerk’s office. The clerks determine the amount of property tax that is actually owned after reviewing things like exemptions. The clerk’s office also maintains delinquent tax records, tax maps, and information regarding TIF districts.

Cook County Treasurer’s Office 

The treasurer’s office is the one that actually bills the taxes and collects the money. After collecting the money, they divide the money and send it to where it is allocated.

How are your property taxes calculated?

The assessor will determine the fair market value of your home. After this, the assessed value of your home is calculated. For residential property owners, the assessed value is 10% of the fair market value. For commercial property, the assessed value is 25% of the fair market value. For example, if your home has a market value of $100,000, the assessed value would be $10,000. The $10,000 is the actual taxable value. Most properties will be reassessed every 3 years. 

The value of your property is determined by many factors. Basically, the number is what the fair value cash for your property would be if it was sold today. In Cook County, the fair market value is based on your home’s characteristics and patterns between how other homes’ characteristics affected their sale value. The assessment of the value of your property can increase for many factors, as well. For example, if your neighborhood is improving, the sales prices of homes in your area are increasing, inflation, or other factors. 

This is an example of what you can expect to see every year from your treasurer:
