HB 4465

This bill amends Illinois' Property Tax Extension Limitation Law (PTELL) to address a technical issue affecting taxing districts that previously granted property tax abatements to nuclear facilities under the Energy Community Reinvestment Act. Starting in levy year 2026, when calculating a taxing district's aggregate extension base (which determines how much property tax revenue can grow each year under PTELL's tax cap provisions), the law will treat any past nuclear facility abatements as if they had been included in the district's extension for that year. This change prevents taxing districts from being permanently penalized under PTELL's tax cap formulas for having provided these economic development incentives, essentially allowing them to recapture the tax revenue capacity they gave up when granting the abatement.
