Who needs workers’ comp in Illinois?
Illinois generally requires employers with one or more employees to carry workers’ compensation insurance. Family members working for the business are typically considered employees. Out-of-state employers with staff working in Illinois must comply with Illinois law.
Sole proprietors and partners are usually not covered unless they elect to be included. Corporate officers and LLC members are typically considered employees; certain owners may be able to exclude themselves if they meet statutory criteria and complete the proper election, subject to state rules and program underwriting.
Independent contractor status depends on control, direction, and the nature of the work—not on tax forms. Prime/general contractors can be responsible for benefits owed to employees of uninsured subcontractors. Always collect COIs from subcontractors and verify endorsements.
What does Illinois workers’ comp cover?

- Medical care for work-related injuries/illnesses
- Wage replacement during lost time (subject to state limits)
- Temporary and permanent disability benefits
- Vocational rehabilitation and maintenance benefits when eligible
- Death benefits for eligible dependents
Doctor choice depends on your setup. With a properly established Preferred Provider Program (PPP) and required notices, treatment can be directed within the PPP. Without a PPP, the injured worker generally has two choices of physician (with chains of referral). Utilization review and preauthorization rules apply—your adjuster will confirm what’s required.
Unique to Illinois: PPP doctor choice and two-choice rule
Illinois allows employers to establish a Preferred Provider Program (PPP). When properly implemented and noticed, employees must choose an authorized treating doctor within the PPP (subject to rules on changes and referrals). If no PPP is in place, injured workers generally have two choices of physician, and each choice includes the chain of referrals from that provider. Proper notices and documentation are essential to preserve medical control.
What does it cost in Illinois?
Premium depends on:
- Payroll by NCCI class code
- Claims history and loss trends
- Experience Mod (if eligible)
- Credits/debits, safety programs, drug-free/managed care, and filed rates
Effective rates vary by industry—from under $1.00 to several dollars per $100 of payroll. For accurate pricing, get a quote with current payroll and class details.

Illinois Workers’ Comp FAQs
Is workers’ compensation insurance required in Illinois?
Yes. Most employers with one or more employees must carry workers’ compensation insurance. Limited exemptions exist; contracts may still require proof of coverage regardless.
Who can be included or excluded?
Sole proprietors and partners are generally excluded by default but can elect coverage. Corporate officers and LLC members are typically considered employees; certain owners may be able to exclude themselves if they meet Illinois criteria and complete the required election, subject to program underwriting.
Who chooses the doctor?
With a properly established PPP and notices, treatment is directed within the PPP. Without a PPP, the injured worker generally has two choices of physician, with chains of referral for each choice. Utilization review and authorization rules apply.
Do 1099 contractors need to be covered?
Not automatically. If the relationship meets Illinois’s employment tests, a contractor may be deemed an employee. Prime/general contractors can be liable for uninsured subs. Require COIs from subs and verify endorsements.
How much does it cost?
Pricing is driven by NCCI class codes, payroll, claims history, and your Experience Mod (if applicable), plus credits/debits. We compare multiple top work comp programs to find competitive Illinois rates.
Does Illinois use NCCI and Experience Mods?
Yes. Illinois follows NCCI for classifications and Experience Mods. Accurate class coding and audit prep help control premiums.
What is the waiting period and how are wage benefits calculated?
Illinois has a 3-day waiting period before wage benefits begin. If disability lasts more than 14 days, benefits may be retroactive to day one. Temporary Total Disability (TTD) is generally 66 2/3% of the average weekly wage, subject to state minimums and maximums.
What posting or notice requirements apply?
Post the IWCC workers’ compensation notice in a conspicuous place. If using a PPP, provide all required PPP notices and provider information. Keep claims reporting contacts accessible and provide Form 45 reporting as required.
What if I’m declined—are assigned risk or PEO options available?
Yes. Illinois participates in the NCCI Assigned Risk Plan for employers who can’t obtain standard coverage. Professional Employer Organizations (PEOs) may also be available depending on industry and underwriting. We’ll compare options for cost and compliance.
How do premium audits work?
Most policies are audited annually at term end. Be ready with payroll reports and quarterly filings, overtime details, subcontractor COIs, job descriptions by class code, and owner/officer inclusion or exclusion forms. Incomplete records can lead to estimated audits and additional premium.
Multi-state employees — how should I set up my policy?
Ensure Illinois is listed properly on your policy (3.A/3.C) when employees live in or regularly work in IL. We configure multi-state coverage so it follows your people.
What is a “ghost policy” in Illinois?
A minimal workers’ comp policy (often excluding owners) used to obtain a COI when there’s little or no payroll. Suitability depends on contract terms and state rules—ask us for compliant options.
Can I get a Waiver of Subrogation or Primary & Noncontributory wording?
Often, yes—subject to program approval and contract specifics. Request early so we can confirm availability, pricing, and any restrictions (blanket vs. scheduled).
What are the penalties for not carrying coverage?
Penalties can include significant fines and liability for benefits if an injury occurs while uninsured. Don’t risk operating without coverage.
