Where exemptions actually apply in the calculation

After equalization, before the rate. The order determines what a given exemption is worth to you.

Exemptions reduce equalized assessed value, not the tax bill directly, and the sequence matters.

The order

Assessed value → multiplied by the county equalization factor → exemptions subtracted → multiplied by the tax rate = your bill.

What that implies

An exemption's cash value is its EAV reduction multiplied by your tax rate. The same exemption is worth more in a high-rate district than a low one — two neighbours in different school districts get different value from an identical exemption.

Worked shape

If an exemption removes $8,000 of EAV and your composite rate is 9%, it is worth about $720 a year. If your rate is 6%, about $480.

Why this is worth knowing

It lets you compare an exemption against an appeal on the same scale. A $10,000 assessment reduction and a $10,000 exemption are worth the same money — but the exemption is a form and the reduction is a hearing.

Stacking

Most homestead exemptions stack: general, plus senior, plus freeze, plus disability where each applies. Check that every one you qualify for appears, not just that some do.

This is general information about how Illinois assessments and appeals work. It is not legal advice, not an appraisal, and not a prediction about your case. Deadlines and rules differ by county — check yours with your Board of Review.
