Taxed Value refers to what taxing agencies did tax to pay for their levies. We use the portion of the tax bill that does NOT go to TIFs to calculate the portion of the composite levy paid by each PIN and then sum up from there.
\[
\mbox{Final Tax to District} = \mbox{Portion of Levy Paid by PIN} = {\mbox{Tax Code Rate}}*{\mbox{Taxable Value of PIN}}
\]
\[\mbox{Equalized Assessed Value} = {\frac{\mbox{final tax to dist + final tax to TIF}}{\mbox{tax code rate}} + \mbox{Exemptions + Abatements}}\]
Table 9.1: FMV of PINs in Cook County Taxed FMV represents the property value that was actually taxed by local taxing jurisdictions(equal to the amount levied) but converted to FMV. We use the the portion of an individuals tax bill that does NOT go to a TIF to calculate the composite levy for taxing jursidictions. This means that the “levy” actually represents the amount collected by the taxing agencies, not the amount that was levied. Therefore the composite levy does not include unpaid taxbills.

Taxed value is the amount of value that was actually taxed in order to pay for taxing agencies levies. It includes frozen EAV within an area + taxable EAV for residential properties net exemptions and abatements. It also includes the equalized assessed value of incentive properties at their current, lower assessment ratios. final_tax_to_dist is used to calculate the amount that was collected by local government agencies and then divided by the tax rate to calculate the amount of value that was taxed, or the taxable equalized assessed value (TEAV).
The Taxed Value, when converted to the Fair Market Value (FMV) represents the amount of value that was taxed out of the full FMV available in Cook County.
Untaxable EAV includes homeowner exemptions for 200 level properties, abatements for other property class types, EAV in the TIF increment, and EAV that has been reduced due to incentive classifications.

The Fair Market Value (FMV) is also called the Market Value for
Assessment Purposes and can be calculated from the av /
loa, or the Assessed Value divided by the Level of
Assessment. However, the values used for the level of assessment are an
approximation for incentive properties since we do not have the PIN
level assessment ratios.

$15 Billion EAV is tax exempt due to homeowners exemptions. All incentive properties combined only have $4 billion EAV that is tax exempt (due to the decreased level of assessment which results in less AV, and therefore, EAV)

Table 11.3: Composite Tax Rate Change Maximum increase in composite property tax rate due to incentives. (five largest and five median). Scenario from if properties that currently receive incentives lost all their value (i.e. most extreme scenario for if we didn’t have incentives and nobody used the land so it had no value.)
