It comes down to one document: the certificate of insurance. If your 1099 subcontractors carry their own workers' comp and hand you a valid certificate, you generally owe no comp premium on them. If they don't — and you can't prove it at audit — most Southeast states treat those uninsured subs as your employees for comp purposes, and your carrier charges you premium on everything you paid them. The 1099 form settles the tax question. It does not settle the workers' comp question.
Most owners assume the 1099 does the work: pay a sub on a 1099, and they're an independent business, not your problem for comp. That's a tax concept, and workers' comp doesn't follow it. Comp classification is a separate legal test, and in Georgia and the wider Southeast the statutes are written to make sure injured workers aren't left with nobody to cover them. So when a subcontractor doesn't carry their own comp, the law reaches up to the contractor who hired them — the "statutory employer" — and puts that exposure on your policy.
That's not a loophole the carriers exploit; it's the whole design of the system. Your comp policy is priced to cover the people who work under you. If a sub arrives with no coverage of their own, from the carrier's point of view they're an extra worker you brought onto the risk — and premium follows the risk.
Every workers' comp policy is audited after the term, and the sub question is where the surprise bills come from. Here's the sequence:
This is why a missing certificate is the number-one cause of a comp audit going sideways. It's not a penalty for wrongdoing — it's the arithmetic of an uninsured worker landing on your policy. If you've never seen how the audit itself unfolds, our guide to what to expect in a workers' comp audit walks through the whole process.
The number scales with your trade's comp rate. Uninsured sub payments get added to payroll and charged at a workers' comp rate per $100 of payroll — and construction classes sit near the top of the rate table. A rough illustration of how fast it adds up on a single season of subcontractor spend without certificates on file:
| Uninsured sub payments (season) | Illustrative comp rate | Approx. added premium |
|---|---|---|
| $40,000 | ~$8 / $100 | ~$3,200 |
| $80,000 | ~$12 / $100 | ~$9,600 |
| $150,000 | ~$18 / $100 | ~$27,000 |
Those rates are illustrative, not filed numbers — but the shape is real. A few missing certificates on a busy year can turn into a five-figure audit bill. Collecting the certificates up front costs essentially nothing, which is what makes this the cheapest risk in construction to fix.
This is where careful contractors still get caught. A sole proprietor or single-member LLC is often exempt from carrying comp on themselves. So the one-person sub shows up, hands you a general liability certificate, and everyone assumes that's covered. It isn't — general liability is not workers' comp. In many states that owner-operator can still be pulled onto your comp at audit unless they have a valid, filed exemption and you hold documentation of it.
So two things matter with single-owner subs: confirm the certificate actually shows workers' comp (not just GL), and if they're claiming an owner exemption, get a copy of the filed exemption for your file. A GL certificate alone will not stop the comp charge.
This is the same certificate discipline that governs additional insured vs. certificate of insurance on your general liability. The habit is identical: get the paper before the work starts, and keep it.

You couldn't produce a valid workers' comp certificate for them. Uninsured subs get added to your payroll and charged premium at their trade rate.
No. Comp classification is separate from tax classification. An uninsured sub can be pulled onto your comp policy regardless of the 1099.
The claim typically flows up to your comp policy as if they were your employee — which is exactly why carriers charge you for uninsured subs in the first place.
Often yes. A sole proprietor may be exempt from comp on themselves and only carry GL. Confirm the certificate shows comp, and get a copy of any filed owner exemption.
An active workers' comp policy with dates covering the period the sub worked for you, the sub's correct legal name, and your business as certificate holder. GL alone is not enough.
