Contractor Insurance You Can Trust

Can a 1099 Sub File a Workers Comp Claim Against Me?

Yes — in certain circumstances, a 1099 sub who was injured can make a workers comp claim against you as the hiring contractor.

  • 1099 subs can request reclassification as employees after an injury
  • If reclassified, a claim falls on your workers comp policy
  • Without coverage for that worker, you pay personally
  • Certificate collection prevents audit charges even if a claim is denied

How a 1099 Sub Becomes a Covered Claim

Workers comp eligibility is determined by whether the injured worker was functioning as an employee, not by whether you classified them as 1099. State workers comp boards apply multi-factor tests — who controlled the work, who provided tools, who set hours, whether the worker had multiple clients — to make this determination.

If the board finds that the 1099 sub was effectively an employee, the claim is treated as a workers comp claim. If your policy was in force and the sub’s work was within its scope, your carrier pays. If your policy excluded that type of work or if the sub was paid outside your reported payroll, you have a coverage dispute on your hands.

Even when classification disputes are ultimately resolved in your favor, the legal defense costs and the time involved are significant. A certificate from the sub showing their own coverage eliminates the dispute entirely — they have their own policy, your carrier isn’t involved.

What to Do If a 1099 Sub Claims Against You

Notify your carrier immediately. Don’t wait to see how the claim develops. The carrier needs to investigate employment status, work conditions, and injury circumstances from day one — not weeks later when evidence has degraded.

Gather everything documenting the independent contractor relationship: the subcontractor agreement, invoices, evidence that the sub worked for other clients, evidence that the sub supplied their own tools, and any safety training or certification they independently provided.

If you have a workers comp certificate from the sub on file, provide it. The carrier can pursue the sub’s carrier for reimbursement even if they initially cover the claim. This is called subrogation, and it protects your EMR from the full cost of a claim that belongs to someone else’s policy.
