What Is a Workers' Compensation Self‑Insurance Trust?
A self‑insurance trust (SIT) lets an Illinois employer set aside funds to cover employee injury claims instead of purchasing traditional workers' comp insurance. The trust is managed by a trustee who pays out claims under the trust's terms. Illinois law permits SITs for employers that meet specific financial and safety requirements.

Eligibility Requirements in Illinois
To qualify, a company must:
- Employ at least 20 workers and pay a minimum of $10,000 in workers' comp premiums annually.
- Maintain a safe‑work record, evidenced by a State of Illinois Workers' Compensation Department (WC) rating of 2 or better.
- Have a proven financial history, including audited financial statements for the last three years.
State approval is required before a trust can be established; the WC will review the proposed trust documents and financial plan.
Funding the Trust
Employers deposit a lump sum or periodic contributions into the trust. The amount typically equals the expected premium cost for the upcoming year plus a reserve for claim variability. The trustee may invest the funds in low‑risk instruments, generating interest income that offsets future contributions.
Benefits and Trade‑Offs
| Attribute | Detail | Context |
|---|---|---|
| Cost Control | Potential savings of 10‑25% over traditional premiums. | Depends on claim frequency and investment returns. |
| Risk Exposure | Employer bears claim costs directly. | Requires robust safety programs to mitigate risk. |
| Administrative Burden | Ongoing trustee oversight and compliance reporting. | May need legal or financial counsel. |
When to Consider a Self‑Insurance Trust
Large employers with stable cash flow and a strong safety record often benefit most. Companies in low‑injury industries—such as manufacturing, IT, or professional services—find SITs attractive. Conversely, firms with high claim volatility or limited financial resources may be better served by traditional carriers.
