IL HB1150

Amends the Property Tax Code to require chief county assessment officers to send first-class mail notification to taxing districts before terminating a property tax exemption due to failure to file the required annual affidavit

Currently, exempt property owners must file affidavits by January 31 each year (or May 31 for certain senior exemptions) confirming any changes in ownership or use, and failure to file can result in loss of exemption at the assessment officer's discretion

The new notification requirement applies specifically to taxing districts that miss the affidavit filing deadline, giving them an opportunity to comply before losing their exempt status

Does not change existing exemptions from annual filing requirements, including burial grounds in smaller counties, United States property, and certain other categories
