Illinois Teachers’ Retirement System Improves to 47.8% Funded, Still 7th-Worst in U.S.

Summary
47.8% funded as of June 30, 2025, Illinois’ Teachers’ Retirement System improved from 45.8% a year earlier but still had less than 50 cents for every dollar owed.
$6.2 billion in state contributions in 2025—up from $3.74 billion in 2016—has not stopped debt from growing because the state’s back-loaded funding plan falls short of full actuarially required payments.
7% assumed annual investment returns are critical to closing the gap; cutting that assumption by 1 percentage point would add $11 billion in taxpayer costs through 2045.
Tier 1 remained deeply underfunded at 47 cents per dollar owed, while Tier 2 held about $1.22 per dollar, effectively subsidizing older, richer benefits for pre-2011 hires.
2045 is the target year for reaching a 90% funded ratio under the Edgar ramp, but the system says the structure shifts rising costs onto taxpayers, newer teachers and other state spending.
With younger teachers overfunding their pensions to subsidize retirees, is Illinois creating a new fiscal crisis for the next generation?
As pension debt consumes 20% of Illinois's budget, which essential public services will be the next to face cuts?
Can Illinois solve its pension crisis without amending the state constitution, or are taxpayers locked into a perpetual bailout?

Overview
As of July 2026, the Illinois Teachers’ Retirement System (TRS) continues to face significant challenges due to persistent unfunded liabilities, which place a growing burden on taxpayers. These challenges are rooted in long-standing structural issues that require policymakers’ commitment to resolve. The Reason Foundation’s 2025 Pension Solvency and Performance Report serves as a benchmark, helping to track TRS’s progress and highlight areas needing improvement. Addressing these structural problems is crucial for protecting the retirement security of current and future teachers, making legislative action and ongoing evaluation essential for the system’s long-term stability.
