Property Assessment and Equalization
Equalization is the process of adjusting the median assessment in each township to the state mandated level of thirty-three and one- third (33 1/30).

Simply put, real property, except farm property, should be assessed at one-third of the market value as of January 1 of the tax year. The local assessor is responsible for setting the value of individual properties. The Supervisor of Assessments adjusts entire township properties so that the median, the middle value when arrayed from high to low, is assessed at one -third of market value. The Illinois Department of Revenue had developed a publication designed to explain, in general terms, the sales ratio and equalization procedures authorized by the state statute. You can access this publication, entitled Publication 136 Property Assessment and Equalization, at their website.
Reasons for Appeal
You have a reasonable complaint if you can support any of the following claims:

1.    The assessor's market value estimate is higher than actual market value. (This claim can be easily supported if you have recently purchased your property or if a professional appraisal is supplied.)
2.    The assessed value is at a higher percentage of market value for your property than the prevailing township, or county median level, as shown in an assessment/sales ratio study.
3.    The primary assessment of the property is based on inaccurate information such as an incorrect measurement of a lot or building.
4.    The assessment is higher than those of similar neighboring properties.
For information regarding the steps in appealing a farm land or farm building assessment, contact your county's Board of Review office.
Has the assessor placed a fair value on my property?
A Legal assessment for tax purposes on any parcel of property in any county in Illinois except Cook County is 33 1/3 percent of the property's market value, excluding farmland and farm-related buildings. To determine whether your particular assessment is fair, you must know two factors:

1. The market value of your property.
2. The assessed value of your property.

The 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.

The assessed value of your property may be obtained from the township or multi- township assessors or from the county supervisor of assessments. Dividing the assessed value of your property by its market value will give you the percentage level of your assessment. By following this procedure for similar property in your area, you can compare your assessment to the average assessment level to determine if your property has been assessed at a fair value.
How do I compare the assessed value of my property with the value of similar property in my area?
You have the right to inspect the assessor's records for any parcel of property, as well as the records for your own property, subject to reasonable regulations set by local officials. All property is reassessed every four years and a complete list of property assessments is published in each county. Any changes in assessments in other years are also published.
What can I do if I think my assessment is unfair?
If your property is outside Cook County, you can file a complaint with that County's Board of Review. If you are dissatisfied with the decision of the board of review, you may appeal to the State Property Tax Appeal Board.

Note: If you think your assessment is unfair it is important to file a complaint before you receive your bill. The "notice of assessment change" will explain the time period for filing a complaint.
How is farmland assessed?
A parcel of land used for agricultural purposes for two years is eligible for a preferential assessment. Farmland is assessed based on it's agricultural economic value rather than being based on 33 1/3 percent of it's market value as is other property. The agricultural economic value 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.

County assessing officials evaluate all farmland in the county based upon it's productivity, taking into account the land's actual use, slope, erosion, flooding, and other factors which affect productivity.

Farm buildings are assessed at 33 1/3 percent of their contributory value of the farm. Farm home sites and residences are assessed at 33 1/3 percent of their market value.
Why are my taxes so high?
Your tax bill depends on two factors:

1. The assessment 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 local officials and is merely a method of fairly distributing the tax burden among all property owners in your community. The actual dollar amount of property tax you must pay is determined by the amount asked for by your taxing bodies.

These taxing bodies annually determine the amount needed to pay for the services they provide. Individual tax bills are calculated to produce this total amount.
Will I be notified if my assessment is going to increase?

Any change in real estate assessments must be published in a newspaper of general circulation in each county every year. Every four years, a complete list of assessments must be published for notification purposes. Individual Assessment notices are sent to each property owner if the assessment has changed.

Banks, savings and loans, or other mortgage holders are required to forward copies of all assessment change notices to affected borrowers within 15 days of the mortgage lender's receipt of the notice.

Township factors, also known as equalization factors are published each year for every township. Individual notices are not sent out if assessments were changed due to an equalization factor.
