In Illinois, workers' compensation is required from the 1st employee - there is no small-team exemption. The 2026 national median cost is $54 a month.

Small businesses in Illinois benchmark against national medians of $45 a month for general liability and $83 for a business owner's policy.

Professional liability runs $88 a month at the national median, and Illinois service businesses are priced on revenue and specialty.

Unlike general liability, workers' comp is not optional once you cross your state's employee threshold. In Illinois, workers' compensation is required from the 1st employee - there is no small-team exemption. Premiums are quoted per 100 dollars of payroll by job classification, which is why the $54 national monthly median stretches widely across trades.

Why only these carriers

Price is easy to compare; claims behavior is not. A policy that saves Illinois businesses a few dollars a month and then fights every claim is the most expensive insurance you can buy. Every carrier listed here clears two public bars - an AM Best rating of A- (Excellent) or better, and a below-median complaint index with state insurance regulators - and any carrier that falls below the bar gets removed.

Price is easy to compare; claims behavior is not. The most expensive insurance is the policy that does not pay. Before any carrier appears in this guide it must clear two public bars: an AM Best financial strength rating of A- (Excellent) or better, and a complaint record at or below the national median in NAIC state filings. A carrier that falls below the bar gets removed from every page on this site.

How quotes work in Illinois

The fastest path to a real number is quoting with two carriers and comparing line by line: same limits, same deductible, same endorsements. A ten-minute quote from each is enough to see whether your business prices above or below the $45-a-month median.

What the business does - carriers price by trade class code
Payroll, if you have employees - drives workers' comp
Annual revenue - drives liability pricing
Business address and years operating in Illinois
Claims history, if any - three clean years helps pricing

Common questions

Are online quotes as accurate as an agent's?

They are built from the same underwriting inputs - trade, payroll, revenue, location, claims. The price is bindable, not an estimate. What an agent adds is judgment on coverage shape, which matters most for unusual or high-risk operations.

What is a certificate of insurance?

A one-page proof-of-coverage document carriers issue on request, listing your policy types, limits and dates. Landlords, GCs and clients in Illinois ask for it before signing - carriers email it same-day, usually free.

Does an LLC need insurance too?

Yes - the LLC protects your personal assets from business liabilities, but the business's own assets stay exposed. Insurance pays claims; the LLC just keeps them away from your house. Most owners carry both.

Is the cheapest business insurance good enough?

Only if the carrier actually pays claims. Before comparing price, check two public numbers: the insurer's AM Best financial strength rating (A- or better) and its complaint index with state regulators (1.0 is average - lower is better). The difference between a good payer and a bad one is usually a few dollars a month; the difference at claim time is everything.

What is the difference between general liability and a BOP?

General liability covers harm you cause to others - injuries and property damage. A business owner's policy (BOP) adds coverage for your own property - gear, inventory, premises - plus business interruption, at a median $83 versus $45 per month.

Do I need workers' comp if I only use subcontractors?

It depends on the state and on whether the subs carry their own coverage - several states count uninsured subcontractors as your employees for comp purposes. Verify with the Illinois Department of Insurance before assuming you are exempt.
