IL HB3808

Creates the Circuit Breaker Property Tax Relief Act to provide grants to Illinois homeowners who experience sudden property tax increases of at least 25% year-over-year (minimum $500 increase) on properties that have not been improved or changed ownership since before 2022

Eligible homeowners must receive a general homestead exemption, be domiciled in Illinois, and have household income not exceeding 4 times the federal poverty level (or be enrolled in programs like SNAP, LIHEAP, or Aid to the Aged, Blind or Disabled)

Maximum grant amount equals one-half of the claimant's property tax bill spike, with payments timed to coincide with final property tax installments and potentially issued directly to local taxing bodies on behalf of claimants

Establishes the Circuit Breaker Property Tax Relief Fund in the State treasury to receive state and other entity contributions for grant payments

Designates the Chief County Assessment Officer to administer the program, establish application procedures, verify eligibility, and makes filing fraudulent claims a Class 4 felony (Class 3 for subsequent offenses)
