Synopsis As Introduced Amends the Property Tax Code. Includes disabled persons within the provisions awarding an assessment freeze homestead exemption to senior citizens. Changes the title of the exemption to the Senior Citizens and Disabled Persons Assessment Freeze Homestead Exemption (now Senior Citizens Assessment Freeze Homestead Exemption). Makes corresponding changes to a cross-reference to the exemption. Provides that, in counties with 3,000,000 or more inhabitants, if an owner fails to file an application for the Senior Citizens and Disabled Persons Assessment Freeze Homestead Exemption during the previous assessment year and qualifies for the exemption, the chief county assessment officer or the board of review, as appropriate, shall issue a certificate of correction setting forth the correct taxable valuation of the property. Amends the freeze provision and the State Mandates Act to require implementation without reimbursement from the State. Effective immediately.
