Illinois tax collections increased by 6.1% in the first half of fiscal year 2026 compared to the same period last year, according to a report from the Illinois Commission on Government Forecasting and Accountability (CGFA). The report shows that state tax collections through December rose by $1.579 billion over fiscal year 2025.
Federal transfers to Illinois declined by $33 million, or 1.6%, during this period. Despite this decrease, the overall increase in state revenue was $1.546 billion, representing a 5.6% rise.
Breaking down the numbers for the first half of FY26: personal income tax collections grew by $592 million (4.2%), while corporate income tax collections fell by $183 million (6.8%). Sales tax revenue went up by $305 million (5.1%). Estate tax collections saw a significant jump of $174 million (54.2%), and insurance taxes and fees increased by $64 million (27%).
Other sources also contributed to higher revenues: lottery collections rose by $41 million (11.2%), gaming taxes increased by $51 million (56%), and sports wagering taxes were up by $97 million, marking a 190.2% increase.
The CGFA attributed these gains partly to new taxes on leased property, sports wagering, and insurance companies, as well as a one-time tax amnesty program.
