Property Tax FAQ

What role do property taxes play? Property taxes have played a major role in financing government since Illinois’ early days. In fact, until the depression of the 1930’s, property taxes were the main source of funding for state government. Today, however, only local governments levy and collect property taxes.

Approximately 6,800 local government units (e.g., municipalities, townships, counties, schools, and park districts) use property taxes to finance the majority of services that they provide to their citizens. The largest share of local property taxes (57 percent) goes to school districts for education. Other services include police and fire protection, street maintenance, and recreation.

What is Illinois’ property tax cycle?
The property tax cycle in Illinois generally extends over a two-year period. A tax year is the year of assessment and reflects the value of real property as of January 1 of that year. The actual tax bills are paid in the year following the tax year (e.g., taxes on a 2023 assessment are paid in 2024).

How is real property assessed in Illinois?
The required assessment level, for tax purposes, on any parcel of real property in all counties (except Cook) is 33-1/3 percent of the property’s fair market value, excluding farmland and farm buildings.

Will I be notified if my assessment is going to change?
Yes, any change in real property assessments must be published in a newspaper of general circulation in each county every year. Every four years when all property is reassessed, a complete list of assessments must be published for notification purposes. In addition, taxpayers must receive a mailed notice of any changes in their assessment from the previous year unless the change was due to the application of an equalization factor by the assessor. Banks, savings and loans, and other mortgage holders also are required to forward copies of all assessment change notices to affected borrowers.

How can I tell if the assessor has placed a fair value on my property?
Once you have verified that the information on your assessment record is accurate, you can use one of the two methods to quickly determine whether or not your assessment is fair.

The first method is to compare the fair market value of your property with recent sales of similar properties in your neighborhood. The fair market value of your property is defined as the price you would accept if a willing and able buyer would offer to purchase your property at today’s prices. This method is appropriate if you have either recently purchased your property on the open market or obtained a professional appraisal.

The second method is to compare the assessed value of your property with similar properties in your neighborhood to determine uniformity in assessments. You can get the assessed value of your property from the township or multi-township assessor, county supervisor of assessments, or county assessor’s office. You have the right to inspect the assessment record for any parcel of property subject to reasonable regulations set by local officials.

This means that if you own a two story home in Prestwick that is half brick and half siding and has a full basement, you should compare your home to other  two story homes in Prestwick that are half brick and half siding and has a full basement.

What can I do if I think my assessment is unfair?
First you should meet with the township assessor. There are several administrative remedies available to you. You can file a complaint with the Will County’s Board of Review. If you are dissatisfied with the Board of Review’s decision, you may appeal to the State Property Tax Appeal Board (PTAB) or file a tax objection complaint in the circuit court. A favorable court ruling is unlikely unless you have exhausted all available administrative remedies.

NOTE: If you think your assessment is unfair, it is important that you pursue administrative remedies in a timely manner. Your “Notice of Revised Assessment Change” lists the filing deadlines. Once you receive you bill, it is generally too late to challenge your assessment.

What will happen if I don’t pay my property taxes?
A lien is placed on your property if you do not pay your property taxes. (A Lien is a legal claim against an asset which is used to secure a loan and which must be paid when the property is sold)The lien may be sold to recover the amount of the tax due. If this action occurs and your property is residential, with six units or less, you may redeem it within two and one-half years of the date of sale. You will have to pay penalties and interest in addition to any taxes due. Other classes of property, such as agricultural and commercial property, have different redemption time periods. If you do not redeem your property, you may lose it.

What property tax relief is available to property owners?
The Property Tax Extension Limitation Law generally restricts the growth in property taxes to 5 percent, or the annual change in the U.S. Consumer Price Index, whichever is less. However, a higher tax rate may be approved by the voters. Originally this law covered property only in Lake, DuPage, Kane, McHenry, and Will counties. Now several other counties qualify, including Cook.

Owner-occupied residences may be eligible for numerous exemptions, which reduces their equalized assessed values. These exemptions include:

  • General Homestead Exemption
  • Homestead Improvement Exemption
  • Senior Homestead Exemption
  • Senior Citizens Assessment Freeze Homestead Exemption
  • Senior Citizens Real Estate Tax Deferral Program (Will County Treasurer)
  • Senior Citizens Circuit Breaker Grant (A yearly property tax Grant)
  • Disabled Veterans Exemption

Additional information that further explains these exemptions can be found in the Frankfort Township Assessor’s office.

How is farmland assessed?
A parcel of land used for agricultural purposes for at least two consecutive years is eligible for a preferential assessment.  Farmland is assessed based on its agricultural economic value (AEV) (i.e., ability to produce income) rather than on 33-1/3 percent of its fair market value.  The AEV is a calculation of an average of prices paid for agricultural products, production costs,and interest rates that are charged by the Federal Land Bank over a five-year period.

Assessing officials value all farmland in the county based upon its productivity, taking into account the land’s actual use, slope, erosion, flooding and other factors that affect productivity.

Farm buildings are assessed at 33-1/3 percent of the contributory value to the productivity of the farm.  Farm home sites and residences are assessed at 33-1/3 percent of the fair market value. Click here for more information.

What factors determine the amount of property tax I will pay?

Your tax bill is based on two factors:

1. The equalized assessed value of your property
2. The amount of money your local taxing districts need to 
operate during the upcoming year.

The assessment on your property is set by the township assessor and is merely a method of fairly distributing the tax burden among all property owners in your community (i.e., the tax base.)  Depending on the tax rate, your tax bill can remain the same, or decrease, even though your assessment is increased if the tax base increases or the taxing districts do not increase their levies. These levies are extended to the taxpayer in the form of a tax rate.
Conversely, your tax bill can increase even though your assessment remains the same, or decreases, if the tax base decreases or the taxing districts increase their levies.
