How Illinois property taxes work

Property tax assessments and collections in Illinois occur on a cycle of approximately two years. During the first year, local appraisers appraise properties to determine the market value of every home in your area. The appraised home value is 33.33% (one-third) of the market value of the home in most of Illinois, although it may vary in some counties.

After local authorities calculate estimated property values, city councils check these values ​​to see if they are correct. These councilors can correspond to the determined values. For example, if they find that a property in a particular county is valued at half its true value, they apply an adjustment factor of 2, doubling the appraised value of everything in the county.

Homeowners also have the opportunity to appeal the appraised value to the district council. If a homeowner is not satisfied with the county council's decision, they can appeal to the state board of basic tax appeals or even the district court.

The state of Illinois also equalizes values ​​across counties by issuing an equalization factor for each county. This ensures that the estimated real estate values ​​are comparable across countries.

Illinois property tax exemptions

There are a number of exceptions that can reduce the appraised value (and therefore property tax payments) in Illinois. The most significant is the General Homestead Exemption, which is available to homeowners living in their primary residence. The Homestead General Exemption equates to a $10,000 reduction in assessed value in Cook County and $6,000 in all other counties.

Another important exemption is the senior housing exemption. This exemption applies to homeowners over the age of 65 and can only be applied to your primary residence. Equivalent to a $5,000 reduction in appraised value, except in Cook County where the reduction is $8,000.

Property tax rates in Illinois

Certain Illinois tax rates are determined based on either the total tax base or the total real estate value with a county. In the second year of the property tax cycle, each tax authority determines its tax based on the tax base and required income. Therefore, the rates change each year based on property values ​​and income needs (which are generally subject to voter approval).

Typically, however, the rate changes are small. Overall tax increases are capped by the Property Tax Extension Limitation Act (PTELL). This law limits property tax growth that results from rising property values. In this situation, income (and hence the tax burden) must not grow faster than the rate of inflation (change in consumer price index) or 5%, whichever is lower.
