Appeals for Bloom Township can be filed until July 26, 2023. More information can be found at cookcountyassessor.com/appeals. To learn more about property assessments and appeals, join the Assessor’s Office at a virtual event and download this helpful guide.

If the percentage increase of a Bloom property’s individual assessment went up less than the total assessed value of 47%, the property could see little change in its property tax bill or even a decline. The full impact of this reassessment on tax bills will be known in late 2024 after all appeals are processed and exemptions are applied.

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.
