Illinois State Budget FY2027 Analysis

Illinois spent $55.9 billion across all funds in FY2027, or $4,395 per resident. All-funds spending counts the general fund, federal grants, and dedicated state funds together — the fairest basis for comparing states, since they differ widely in how much they route outside the general fund.

The general fund — the discretionary portion the legislature actually debates — was $55.9 billion, or 100.0% of total spending. The remainder is largely federal grants (Medicaid above all) and dedicated revenues such as fuel taxes earmarked for highways.

Reserves in the rainy day fund stood at $2.5 billion. Because nearly every state is constitutionally required to balance its operating budget, reserves rather than borrowing are how states absorb revenue shortfalls in a downturn.

Illinois' FY2027 budget, signed June 16, 2026 as Gov. JB Pritzker's eighth consecutive balanced plan, spends $55.9 billion in general funds against roughly $56.0 billion in expected revenues (including transfers) — the largest budget in state history and about $800 million above FY2026's $55.1 billion. Balance was achieved almost entirely on the revenue side: more than $800 million in new business-focused taxes, including a $300 million cap on corporate net-operating-loss deductions, a $200 million social media tax and a 0.2% digital-asset sales tax worth $60 million, plus $185 million in fund sweeps ($150 million from the Road Fund). Discretionary spending growth was held under 0.5%. K-12 Evidence-Based Funding rises $350 million to a $9.3 billion program level, MAP college grants hold at $721.6 million, and a $250 million housing package funds missing-middle infrastructure and down-payment aid. Statutory pension contributions of nearly $12 billion are fully met but remain more than $5 billion below the $17 billion actuaries recommend, against $143.5 billion in unfunded liabilities. The Budget Stabilization Fund — about $2.5 billion, roughly two weeks of operating cover — grows just $197 million, and only from other state funds. Election-year politics shaped the mix: no income or sales tax rate increases, a gas-tax indexation delay from July 1 to January 1, and a 10-day August school-supplies sales-tax holiday, while a 10% digital advertising tax framework awaits legal review.
