Illinois has enacted a significant overhaul of its property tax sale system aimed at protecting homeowners from losing equity after tax foreclosures. The new legislation requires that any surplus funds from tax foreclosure sales be returned to the original homeowners, aligning state law with a 2023 U.S. Supreme Court ruling. This ruling determined that homeowners whose properties are foreclosed due to unpaid taxes have a right to recover any equity that exceeds their tax debt.

Delinquent property taxes in Illinois have historically been sold to private investors known as tax buyers. These investors could foreclose on properties and retain the full equity if the original owners failed to pay within the allotted period. The reform targets this practice by establishing a public auction system for all foreclosed properties, which mandates returning surplus proceeds to homeowners. It also extends the time homeowners have to redeem their property from 30 to 36 months, providing additional leeway to prevent loss of homes.

Another critical component of the reform is the creation of a temporary compensation fund for homeowners who recently lost equity under the previous rules or are currently navigating the foreclosure process. The bill also prescribes phasing out the sale of tax debts to private investors in Cook County by 2030, introducing a pilot program allowing the county to manage tax debts on a limited number of owner-occupied homes to gauge the new approach's success.

This legislative package, known as House Bill 4537, received bipartisan backing and the support of numerous housing advocacy groups, who highlight its potential to stop the erosion of generational wealth, particularly in majority-Black communities disproportionately affected by past practices. The reforms come after investigative reports revealed that since 2019, tax buyers had acquired over 1,000 owner-occupied homes in Cook County, many with minimal tax debt, stripping residents of valuable equity.

Though Gov. JB Pritzker has yet to sign the bill, advocates expect its approval. The governor's office has stated a thorough review will precede any decision. Legal experts involved in the 2023 Supreme Court case praised the bill for incorporating the essential elements to restore homeowners’ rights, although they noted Illinois’ procedures remain more complex than in other states and recommended further improvements.
