What If a Subcontractor Doesn't Have Insurance? Where It Costs You, and Your Options
A sub without insurance doesn't make the risk disappear. It moves it to whoever hired them. That usually shows up in one of three places: a claim from their work, your general liability premium audit, or workers' comp for their injured workers. This guide covers each, why a signed waiver doesn't fix them, what your options are before work starts, and what to do when a sub's coverage lapses partway through a job.
When a subcontractor has no insurance, the cost can land on the contractor who hired them in three ways: a claim from their work is defended by your own policy, your general liability premium audit may rate what you paid them like your own crew's work, and in many states you become responsible for workers' comp benefits to their injured workers. A signed waiver doesn't change any of those. Your options are to have them insured before they start, accept a valid workers' comp exemption for a sub who genuinely works alone, price the audit charge in, or hire someone else.

Where the cost lands
The sub's insurance exists so that losses from their work land on their policy. Without it, each of these lands on you instead:
| Where | What happens | When you find out |
|---|---|---|
| A claim from their work | Property damage or an injury the sub caused is claimed against you as the contractor in charge. With no policy of theirs to tender it to, your general liability defends it and it goes on your loss history | When the claim arrives, often long after the job |
| Your general liability audit | Many contractor policies rate payments to insured subs lightly or not at all, and payments to uninsured subs like your own crew's work, under the class code for what they did | At the premium audit after your policy year ends |
| Workers' comp for their crew | In many states the hiring contractor is responsible for workers' comp benefits to an uninsured sub's injured workers, and your workers' comp audit can add the sub's payroll to yours | When someone is hurt, or at the workers' comp audit |
The workers' comp line is usually the largest, and it's written into state law rather than left to your policy. Indiana is a clear example: a contractor that sublets work without getting proof of the sub's workers' comp coverage is liable for the sub's injured workers to the same extent as the sub (Indiana Code 22-3-2-14). Many states have a similar rule; ask your agent or attorney about yours.
The audit charge is not a theory either. In Continental Casualty v. King (Tennessee Court of Appeals, 2006), a roofing contractor who had reported no employees paid a $750 minimum workers' comp premium. The audit added more than $14,700 for roofers working for him and his subs without their own coverage. He argued they were all independent contractors; the court upheld the insurer's judgment. The two audits are covered in detail in general liability premium audits and subcontractors and workers' comp audits and subcontractors.
Why a signed waiver doesn't fix it
The common workaround is to have the uninsured sub sign a waiver or a hold harmless, promising to cover any loss themselves. It feels like protection. Look at who each cost is owed to, though:
- The audit charge is between you and your insurer, under your policy's rating rules. A document the sub signed isn't part of that.
- Workers' comp for their crew is set by state law. Where the law makes you responsible, a private agreement can't move that back.
- A claim from their work is the one a hold harmless agreement is meant for. But the promise is only worth what stands behind it, and for an uninsured sub that's their own bank account.
A signed waiver is still worth having as a record that you asked and they declined. It just isn't insurance.
Your options before work starts
| Option | When it works | Watch for |
|---|---|---|
| They get insured first | Almost always the answer. A small contractor can usually buy general liability through an agent quickly, and the certificate follows once the policy is bound | The policy has to be in force before they start; it won't reach back to work already done |
| A workers' comp exemption | A sole proprietor or owner with no employees, in a state that allows it. Some states issue an exemption certificate | It usually covers only the person named on it. If they bring a helper, the helper isn't covered. It does nothing for general liability |
| Price in the audit charge | A small, short job where you decide to carry the sub's exposure on your own policy | Ask your agent what the charge will be first; workers' comp for their crew can still land on you |
| A project insurance program | Large projects where the owner or GC buys coverage for every enrolled sub (OCIP or CCIP) | Enrollment usually covers work on that site only, and often not their auto |
| Hire someone else | When none of the above fits the job's risk | The cheapest bid without insurance often isn't the cheapest job |
Licensed trades are a special case: in some states a contractor must carry liability insurance to hold the license at all. A sub in one of those trades without insurance may also have a license problem. The state requirement guides, such as Texas and Florida, cover what each state requires.
When coverage lapses partway through a job
More often than a sub with no insurance at all, you'll have a sub whose insurance ran out while they were working for you: a certificate on file from April, a policy that ended in June, work through September. To the auditor, the months after June can look exactly like an uninsured sub.
Ask the same day
Request the renewal certificate as soon as the old one expires. Usually the policy renewed and nobody sent you the new certificate.
Decide whether they keep working
If the renewal doesn't arrive, decide whether the sub stays on site. Your subcontract should already say that coverage is a condition of working.
Mind the gap
If the policy really lapsed, a new one starting later doesn't cover the dates in between. Note which dates and payments fall in the gap; that's what the audit will look at.
Check every line
General liability, auto and workers' comp often renew on different dates. A current GL certificate says nothing about workers' comp.
Keeping uninsured subs off the job
Every cost above is cheaper to prevent than to argue about. Before any sub starts:
- A certificate for general liability, auto and workers' comp, or the state's exemption paperwork in place of workers' comp, covering the dates of the work.
- The name on the certificate matches the payee. The name on the W-9 is what ties the checks you write to the policy the auditor sees.
- The endorsements your contract requires, not just the limits. See what an insurance endorsement is.
- Coverage as a condition of starting, written into the subcontract, so "no certificate, no start" isn't a negotiation on the day.
Then keep each policy's expiry date in front of you, because a sub who was insured at the start can be uninsured by the end. Getting subs to send their COIs covers the asking, and COI tracking software keeps the dates.
How TrackMyVendor automates this
- Set the coverage and minimums you require, and a sub with a line missing, lapsed or below your minimum shows as Non-Compliant.
- Every policy is tracked on its own dates, read off the certificate, so a lapsed workers' comp line shows even when general liability is current.
- Alerts at 90, 60, 30 and 7 days before each policy expires, to your team and to the sub with the upload link for the renewal. Starter
We track the certificates and exemption documents you're sent. We can't tell you how your insurer will rate an uninsured sub at audit, or what your state's workers' comp law makes you responsible for; your agent and attorney can.

Subs upload their certificates and exemption paperwork through one link — no account, no portal. Every policy is read, checked against what you require and tracked on its own dates. Your first 25 contractors are free.
