Workers comp vs general liability: which one covers what
I have watched business owners discover the difference between these two policies in the worst possible way: a denied claim. Workers compensation insurance covers your employees when they get hurt on the job. General liability insurance covers everyone else. These are the two most important small business insurance policies any employer carries, and they do not overlap by a single dollar. Filing the wrong claim on the wrong policy gets you a denial letter, and you pay the full cost out of pocket while you figure out which carrier should have been handling it.
How workers comp premium works and why it hits payroll
Workers comp pays for medical treatment, lost wages, and rehabilitation when an employee is injured or becomes ill because of their job. The policy covers the employee regardless of fault. Your worker does not need to prove you were negligent. In exchange for guaranteed coverage, employees give up the right to sue you for workplace injuries. This tradeoff, called the grand bargain, is the foundation of every state workers comp system.
What makes workers comp unique among business insurance is that the premium is calculated directly from your payroll. The carrier assigns each employee a workers comp class code based on their job duties, then applies a rate per $100 of payroll for that code. A roofing company with $500,000 in payroll under class code 5551 pays dramatically more than an accounting firm with $500,000 in payroll under class code 8810. Your experience modification rate then multiplies the result, rewarding safe workplaces and penalizing those with claims history.
The workers comp cost per employee varies from under $200 per year for low risk office work to over $5,000 per year for high risk construction trades. That range makes workers comp the single most variable insurance cost on a small business balance sheet. The payroll figures used for premium calculation follow the same wage definitions in IRS Publication 15, though workers comp auditors include some compensation types that the IRS excludes from withholding.
Most states require employers to carry workers compensation insurance once they have even one employee. The exact threshold varies by state. Texas is the only state where private employers can opt out entirely, though doing so removes the grand bargain protection and exposes the employer to employee lawsuits with no cap on damages. If you are unsure whether your state requires coverage, the test is simple: do you have employees? If yes, you almost certainly need workers comp.
General liability covers a completely different universe of risk
General liability pays when your business causes bodily injury or property damage to a third party, meaning anyone who is not your employee. A customer trips over a cord in your store. A plumber floods a client's basement. A landscaper's mower throws a rock through a neighbor's window. The standard commercial general liability policy (form CG 00 01, if you want to look it up on your own declarations page) covers these claims plus advertising injury and personal injury like defamation.
The general liability insurance cost for a small business typically runs $500 to $2,000 per year for a standard policy with $1 million per occurrence and $2 million aggregate limits. Those limits are the industry default. Most GCs, landlords, and clients who require proof of GL coverage expect to see at least $1 million/$2 million on the certificate. If your business faces higher exposure, an umbrella policy adds coverage above those limits for a few hundred dollars more per year.
One detail that trips up small business owners: GL policies come in two forms. Occurrence policies cover any incident that happens during the policy period, regardless of when the claim is filed. Claims-made policies cover only claims that are both reported and occur during the policy period. If you cancel a claims-made policy and someone files a claim next year for an incident that happened last year, you have no coverage. Most small businesses should carry occurrence policies. If your agent quotes you a claims-made GL policy, ask why.
Unlike workers comp, general liability premiums are based on revenue, square footage, and industry classification rather than payroll. No state legally requires general liability insurance, but the contractual requirements are nearly as binding. A contractor without GL will not get on most job sites. A tenant without GL will not sign most commercial leases. General liability for small business owners is technically optional and practically mandatory.
No state requires general liability, but try signing a commercial lease without it.
Many small businesses buy general liability as part of a business owner's policy, or BOP, which bundles GL with commercial property insurance at a discounted rate. A BOP is often the cheapest way to get GL coverage if you also need property insurance for your equipment, inventory, or office space. The tradeoff is that BOP policies have standardized coverage limits that may not match what a GC or client requires, so check the declarations page against whatever certificate requirements you are being asked to meet.
The same incident, two different claims
A customer at your restaurant slips on a wet floor. That is a general liability claim. An employee at your restaurant slips on the same wet floor five minutes later. That is a workers comp claim. Same puddle, same injury, completely different policy.
The most common version of this mistake I see is an owner who calls their "insurance company" to report a claim without specifying which policy it belongs to. The intake rep routes it to the wrong adjuster. The claim gets denied, weeks pass, and now you are resubmitting to the correct carrier with a delay that the injured party's attorney will use against you.
Filing a workers comp claim on your GL policy wastes weeks and gives the claimant's attorney free ammunition.
When this is wrong: employers who carry general liability but not workers comp because they believe GL covers "everything." The standard GL policy contains an employer's liability exclusion that specifically removes coverage for injuries to your own employees. If an employee is injured and you have no workers comp, you are personally liable for their medical bills, lost wages, and any lawsuit they file. In states that mandate workers comp, operating without it is also a criminal offense that can result in fines of $1,000 per day or more.
Workers comp for sole proprietors who carry a ghost policy creates its own confusion. A ghost policy satisfies a GC's requirement for proof of workers comp coverage, but it covers zero employees because the owner is excluded. If a customer or bystander is hurt on the sole proprietor's job site, the ghost policy does not cover that either. That is what general liability covers. A sole proprietor working a construction site needs both certificates in their truck.
How the policies interact when subcontractors are involved
A GC asks a sub for "proof of insurance" and the sub is not sure whether that means workers comp, general liability, or both. The answer is almost always both.
The GC needs the sub's workers comp certificate so their own carrier does not add the sub's payments to the GC's auditable payroll at the year end workers comp audit. They need the sub's general liability certificate so the sub's work is covered if it damages the property or injures a third party. Most GCs also require the sub to name the GC as an additional insured on the GL policy. An additional insured endorsement extends the sub's GL coverage to protect the GC from claims arising from the sub's work. Without it, the GC's own GL policy responds to a claim that the sub caused, and the GC's premiums go up.
When a construction worker falls off scaffolding and lands on a pedestrian below, both policies activate on the same incident. The worker's injuries are a workers comp claim. The pedestrian's injuries are a general liability claim. One incident, two adjusters, two separate claims processes. The sub's workers comp carrier may later pursue subrogation against the GC's general liability if the GC's negligence caused the fall. The injured worker collects workers comp benefits regardless of who was at fault. The carriers sort out the rest.
When this analysis breaks down: states with exclusive remedy exceptions that allow employees to sue employers for intentional acts. In those cases, the workers comp grand bargain does not fully shield the employer, and the GL exclusion for employee injuries may leave a coverage gap that only an employment practices liability policy fills.
One scaffolding incident can trigger two separate insurance claims under two separate policies with two separate adjusters.
Workers comp for LLC owners adds another layer. In many states, LLC members can exclude themselves from their own workers comp policy. If the excluded owner is injured on a job, workers comp does not cover them. Their personal health insurance might deny the claim because it happened at work. I have seen owners stuck with $40,000 in medical bills because of this exact coverage gap between two policies that both say the other should pay. When this advice fails: single-member LLCs in states like California that do not allow owner exclusions from workers comp. In those states, the owner must be covered, which eliminates the coverage gap entirely but increases the annual premium.
What neither policy covers
Professional mistakes are not covered by workers comp or general liability. If you give bad advice, make an error in a deliverable, or fail to perform contracted services, neither policy responds. That risk falls under professional liability insurance, also called errors and omissions. Accountants, consultants, architects, and technology companies need E&O coverage in addition to GL.
Vehicle accidents during work are also excluded from standard GL policies. If your employee rear ends someone while driving a company vehicle to a job site, your commercial auto policy covers the third party's injuries and vehicle damage. If they are driving their own car on company business, your hired and non-owned auto endorsement covers it. The employee's own injuries in either scenario are a workers comp claim, but the third party damage is neither GL nor WC.
What to check this week
Pull both your workers comp and general liability declarations pages. Verify the policy periods overlap with no gaps. A lapse in either policy, even for a few days, creates exposure that could cost tens of thousands in an uncovered claim.
Confirm your workers comp policy lists the correct class codes for every employee. If job duties have changed since the policy was written, call your agent and update the classifications now rather than waiting for the audit to reclassify them retroactively at a higher rate.
If you hire subcontractors, collect both a workers comp certificate of insurance and a general liability certificate from every sub before they start. Verify the GL certificate names you as additional insured. Missing a workers comp certificate inflates your premium at audit. Missing a GL certificate means you carry the liability for damage they cause on your project.
If your GL is currently part of a BOP, check whether the BOP limits satisfy the certificate requirements your clients and GCs are asking for. A $500,000 BOP limit will not satisfy a GC who requires $1 million per occurrence. Ask your agent about upgrading the limits or splitting the GL out into a standalone policy.
Frequently asked questions
Do I need both workers comp and general liability?
Almost certainly. Workers comp is legally required in most states once you have employees. General liability is contractually required by most clients, landlords, and general contractors. They cover completely different risks. Carrying only one leaves a gap that a single denied claim will expose.
Does general liability cover employee injuries?
No. The standard general liability policy (CG 00 01) contains an employer's liability exclusion that specifically removes coverage for injuries to your own employees. That risk is covered by workers compensation insurance. If you carry only GL and an employee is hurt on the job, the claim will be denied.
What is an additional insured endorsement?
An additional insured endorsement extends your general liability policy to cover another party, usually a general contractor or property owner, for claims arising from your work. Most GCs require subs to add them as additional insured before starting a project. The endorsement protects the GC from being sued for something the sub caused.
Which policy covers a subcontractor's injury on my job site?
The subcontractor's own workers comp policy covers their injury. If the sub does not carry workers comp, your carrier may add the sub's payments to your auditable payroll and charge you premium for their uninsured workers. Collect a workers comp certificate from every sub before they start work to prevent this.
