Bill > SB0178

This bill amends the Illinois Income Tax Act to create a new tax credit for homeowners who spend money soundproofing their residential homes against aircraft noise from O'Hare International Airport. Starting from December 31, 2025, taxpayers can claim a credit equal to the amount they spend on materials, labor, and professional services for soundproofing, with the work needing to comply with the Illinois Residential Building Code Act. The credit is available for homes located within specific noise contour zones around O'Hare, including addresses within the 65 DNL (Day-Night Average Sound Level) Build-out Contour, an alternative 65 CNEL (Community Noise Equivalent Level) contour, or within 20 miles east or west and 3 miles north or south of an east-west runway. The credit cannot reduce a taxpayer's liability below zero, but any excess credit can be carried forward and applied to tax liability for up to 5 subsequent years. Notably, this tax credit is exempt from the standard automatic sunset provisions that would normally cause it to expire, ensuring its long-term availability for eligible homeowners.
