The amnesty program is part of Illinois' Fiscal Year 2026 budget (House Bill 2755), signed into law on June 16, 2025. By extending relief to taxpayers, Illinois aims to bolster compliance while generating significant short-term revenue. Similar programs in 2003, 2010, and 2019 proved highly successful in bringing delinquent taxpayers back into the system.
