Employer benefit plans in Illinois

1,697 insured group benefit plans sponsored by Illinois employers are on public Form 5500 record, carrying 7,776 Schedule A contracts. A row is one plan, so an employer that files two of them is counted twice. Reported premium totals $9.5B, with $253.4M in disclosed broker commissions. Renewals cluster on January 1: 76% of these plans have policy years ending in December.

These are the plans of 250 participants or more that disclosed a broker commission — the ones we publish as pages. Smaller plans, self-funded plans and retirement plans are on file too and open from search.

Participants are line 5 of each filing: everyone in the plan, retirees and separated members included. A plan sponsored in Illinois can cover people in every state, and an employer with two plans is counted in both.

When Illinois plans renew

Employer plans by typical renewal, the 1st after the policy period ends. A plan’s month comes from one contract: the one with the largest disclosed commission on its most recent filing, preferring a medical contract when the plan has one.
