IL HB4129

Amends the Parking Excise Tax Act (35 ILCS 525/10-5) to define "booking intermediary" as any person or entity that facilitates parking reservation transactions between operators and customers.

Excludes fees or charges retained by or paid to a booking intermediary from the definition of "purchase price" subject to the parking excise tax, provided those amounts are not remitted to the parking operator.

Clarifies that "purchase price" includes all charges related to obtaining parking such as markups, service fees, convenience fees, facilitation fees, cancellation fees, and overtime fees, regardless of how they are labeled.

Specifies that non-optional separately stated charges are presumed to be part of the parking purchase price for tax purposes.

Maintains existing exclusions from "purchase price" including optional separate charges, dishonored check fees, finance charges, isolated sales by non-regular sellers, and amounts added due to the parking tax itself.
