Most Illinois businesses need workers' compensation once they have their first employee, general liability that clients and landlords insist on, and property or a package policy for their equipment. Workers' comp is the coverage Illinois law actually forces on you: under the Illinois Workers' Compensation Act (820 ILCS 305), an employer must carry it once it has even one employee, full-time or part-time, and the Act's list of covered enterprises is so broad that almost every business with staff is automatically included (820 ILCS 305/3).
Who this is for: Illinois owners, from a one-van contractor in Peoria to a 30-person shop in Chicago, who want to know what the state requires, what their contracts require, and how to buy it without overpaying.
The short version
- Workers' comp is required from your first employee, even a part-time one, under the Illinois Workers' Compensation Act (820 ILCS 305).
- You buy on the open market. Illinois is a private, competitive market with no state fund, so private carriers compete for your business, with a state plan of last resort as the backstop if you are hard to place.
- Owners are treated differently by entity. Sole proprietors and partners are outside the policy unless they elect in, while corporate officers and LLC members are inside unless they notify the carrier to exempt out.
- Construction gets the heaviest enforcement, and a general contractor can owe benefits for an uninsured subcontractor's injured workers (820 ILCS 305/1(a)(3)).
- General liability is not a state mandate, but nearly every lease, client contract, and general contractor requires it before you can start work.
What Illinois actually requires
Only a couple of these are true legal mandates. The rest get required by the people you do business with, which in practice is just as binding.
| Coverage | Required by Illinois law? | Who needs it | What is at stake |
|---|---|---|---|
| Workers' compensation | Yes, from the first employee | Any business with an employee, full-time or part-time | Daily fines, a 10,000 dollar minimum penalty, a possible felony, a direct lawsuit |
| Commercial auto | Yes, if you own or use business vehicles | Any business-owned or leased vehicle | Registration problems, uninsured liability |
| General liability | No state mandate | Required by most leases, clients, and general contractors | Lost contracts, blocked from a job site |
| Professional liability (errors and omissions) | No state mandate | Consultants, tech, design, and accounting firms, often by contract | Uncovered claims, lost contracts |
| Commercial property or a package policy | No state mandate | Anyone with a space, inventory, or equipment; landlords often require it | Out-of-pocket losses, lease default |
What business insurance costs in Illinois
These are illustrative annual ranges for small Illinois businesses, not quotes. Your real price depends on payroll, revenue, claims history, and the exact kind of work. Illinois prices workers' comp off advisory rates and loss costs filed by NCCI and approved by the Illinois Department of Insurance, and as of mid-2026 those have edged slightly down, with voluntary loss costs about 1.2 percent lower effective January 1, 2026.
| Business type | Workers' comp (est.) | General liability (est.) | Package policy (est.) |
|---|---|---|---|
| Office or professional services | 600 to 2,400 dollars | 500 to 1,900 dollars | 1,100 to 3,600 dollars |
| Restaurant or cafe | 2,500 to 10,000 dollars | 1,400 to 5,000 dollars | 4,000 to 14,000 dollars |
| Landscaper or small contractor | 3,500 to 14,000 dollars | 1,100 to 4,000 dollars | Usually separate policies |
| Light manufacturing shop | 2,500 to 9,000 dollars | 1,000 to 4,000 dollars | 3,500 to 12,000 dollars |
| Retail store | 1,200 to 5,000 dollars | 800 to 3,000 dollars | 2,200 to 8,000 dollars |
The 14 workers comp questions Illinois owners ask
Workers' comp is where most of the confusion and most of the risk live, so we wrote a plain-English guide for every common situation. Start with the Illinois workers comp overview, then jump to the one that matches your business:
- I own an LLC
- I am a sole proprietor
- I own a corporation (C-corp or S-corp)
- We are a partnership
- We are a nonprofit
- My workers are 1099 contractors
- I only have part-time or seasonal staff
- I only employ family members
- My team is remote or out of state
- What happens if I do not have it
- How much it costs
- How to get it, even if I have been turned down
- What I need for a contractor license
A Naperville example
Illustrative, not a quote. A four-person general contractor in Naperville runs the business as an LLC with two working members and two field employees. Because the business has employees, Illinois requires workers' comp from day one, and the two field workers must be covered. The two members are on the policy by default and can each notify the carrier in writing to exempt themselves out, while the employees stay covered no matter what. When a builder they want to work for asks for proof of coverage, the LLC already has a policy and can produce a certificate the same day. See the trade detail on our workers comp for contractors page.
Real questions Illinois owners ask
Do I need workers comp for my Illinois business?
Almost certainly, if you have employees. Illinois requires workers' comp once you have even one employee, full-time or part-time, so most businesses with any staff must carry it from the first hire.
I just hired my first employee in Illinois. Do I need it right away?
Yes. Illinois requires coverage from the first employee, including a part-time one, so the policy should be in place before that person starts work.
Do I have to cover myself as the owner?
It depends on your entity. Sole proprietors and partners are out by default and may elect in, while corporate officers and LLC members are covered by default and must notify the carrier in writing to exempt out.
Is general liability insurance required in Illinois?
The state does not make general liability mandatory for most businesses, but landlords, clients, and general contractors almost always require it before they will sign with you, so in practice you usually need it.
What happens if I skip required workers comp?
It is a crime. Knowingly going uninsured is a felony, negligently going uninsured is a misdemeanor, each day is a separate offense, and the state can add a civil penalty of up to 500 dollars a day with a 10,000 dollar minimum.
Does Illinois have a state workers comp fund?
No. Illinois is a private, competitive market with no state fund. You buy from a private carrier, and if no carrier will take you, the Illinois Workers' Compensation Assigned Risk Plan is the guaranteed backstop.
I am based out of state with a worker in Illinois. Do I need coverage here?
Generally yes. If an employee's work is based in Illinois, you usually need Illinois coverage for them, no matter where your company is based. We can add Illinois to your policy or write a separate one.
Why Illinois owners choose Morrow
- We shop the right market for you. In Illinois you buy workers' comp on the open market from any private carrier licensed in the state, because Illinois has no state fund; if no carrier will take you, the Illinois Workers' Compensation Assigned Risk Plan (the assigned-risk plan) is the guaranteed fallback, so we can shop your rate freely and still keep a backstop for hard-to-place work.
- We catch pricing mistakes. Your price depends heavily on the category your work falls into for pricing (the class code). Put people in the wrong category and you overpay for years. We review your payroll and classifications before you buy.
- Proof of coverage, fast. Need a certificate (proof of coverage) for a general contractor or a landlord before Monday? We turn those around the same business day for most carriers.
- We help lower the score that drives your price. Insurers give you a score based on your past claims that raises or lowers your cost (the experience modification rate). We review it each year, flag errors, and connect you with return-to-work and safety resources that bring it down.
- Real people when a claim happens. When someone gets hurt, we stay involved through the life of the claim, not just at renewal.
