IL HB3634

Amends the Property Tax Code to establish quantifiable standards for charitable property tax exemptions for not-for-profit hospitals and hospital affiliates under Section 15-86.

Hospital applicants qualify for exemption if the value of qualifying charitable services and activities (charity care, health services to low-income individuals, government subsidies, Medicaid support, and other relief activities) equals or exceeds the hospital's estimated property tax liability for the year.

Denies exemption to hospitals serving multiple municipalities if the subject property is in a municipality with 10% or less of the hospital's total patient population AND the municipality provides services to 50% or more of the hospital's properties in that county AND the hospital's net income is 8% or more of revenue without the exemption.

Requires hospital applicants to submit detailed applications with financial records and sworn verification from the Chief Executive Officer, including exhibits showing charitable service values and estimated property tax liability calculations.

Properties owned or operated by for-profit entities do not qualify for exemption, though mixed-use parcels may receive partial exemptions proportional to qualifying use; effective immediately upon enactment.
