Allows gross income tax deduction for amounts paid for removal of lead, asbestos, sodium, chloride, and other contaminants from taxpayer's property.

This bill allows New Jersey taxpayers to deduct up to $45,000 annually from their gross income for specific property cleanup costs. It covers lead paint removal (by certified contractors), asbestos abatement (by licensed contractors), lead pipe/plumbing replacement, soil remediation, leaded window replacement, and water treatment system costs for sodium/chloride-contaminated well water. The deduction applies to primary residences, owner-occupied homes, or rental units, with requirements including municipal affidavits for lead/asbestos work and proof of contamination for water treatment. The provision expires December 31, 2025, and is available regardless of taxpayer income.
