2023 Reassessments in Calumet Township

The Assessor’s Office follows a triennial reassessment cycle, which means one-third of the county is reassessed every three years. The townships scheduled for reassessment in 2023 can be found here. When a property is reassessed, the property owner is mailed a Reassessment Notice, which contains the property’s address, characteristics, and estimated Fair Market Value. The estimated Fair Market Value listed on the Reassessment Notice will be reflected on tax bills in 2024.

How Assessments Relate to Property Taxes 

Assessments, under Illinois law, should fairly reflect market values. The Assessor’s Office estimates market values by using a mass appraisal model that analyzes sales trends. Mass appraisal models rely on accurate data. If a property owner believes the characteristics listed for their property are inaccurate, or their property is worth less than the Assessor’s Office’s estimate of its value, the owner is entitled to file an appeal.

These assessments divide up the total tax levy of that property’s township, school district, and other taxing districts. A property owner’s share of taxes depends on how their property’s assessment relative to the total assessed value of their area. Therefore, an increase in a property's assessment does not lead to the same increase its tax bill.

Tax levies pay for services such as schools, parks, libraries, and pensions. The Assessor does not set levies or tax rates. Increases in assessments do not increase the revenue received by taxing districts.
