IL HB4750

Amends the Property Tax Code to require property tax bills include information notifying taxpayers of each exemption available to their specific category and the application deadlines for those exemptions.

Exemption information must meet one of two formatting standards: (1) displayed on the front of the first page in font larger than principal text (minimum 12-point), in a distinct format with contrasting type style, or (2) included as separate municipal informational material in the bill envelope.

Information included in the envelope option must cover tax deferral programs, assistance for taxpayers with affordability difficulties, assessment calculation methods, and appeal options for incorrect assessments.

Maintains existing requirements for tax bills to itemize tax rates by district, show homestead exemptions, equalization factors, fair cash value determinations, and year-over-year tax differences.

Creates a mandatory statutory duty for counties to provide these disclosures; failure to mail bills does not affect tax validity or taxpayer liability.
