Illinois retirement plan filings, 2025
Plan years beginning in 2025, as filed with the Department of Labor.
Form 5500 information is as filed by the plan administrator with the Department of Labor and may be amended. Figures reflect the plan year shown, not current balances.
For plan years beginning in 2025, 1,486 pension plans based in Illinois filed the full Form 5500, 461 of them with 100 or more participants (449 defined contribution, 12 defined benefit). Filing for 2025 is still open, so these counts are partial and will rise.
