INC TX-PROP TX CREDIT

Maddy summaryThis bill makes Illinois' residential property tax credit refundable starting in 2026. It directly affects homeowners who claim the credit by allowing them to receive a cash refund if the credit amount exceeds their income tax liability. The key change is that taxpayers will get the excess credit amount paid back to them as a refund, rather than only reducing their tax bill. This refund won't count as income for means-tested programs (like food assistance), unless federal law requires otherwise. The change applies to tax years beginning January 1, 2026, and updates the existing credit structure under the Illinois Income Tax Act.
