Subcontractor or Employee? How Worker Classification Decides Your Comp Bill
6 min read · Updated June 20, 2026
“He’s a 1099, not my employee” is the sentence that precedes a lot of surprise audit bills. The label you put on a worker doesn’t control how they’re treated for workers’ comp — the working relationship does. Here’s the test that actually decides it.
Why the 1099 isn’t the answer
A 1099 is a tax form. Workers’ comp and state labor agencies apply their own tests for whether someone is a genuine independent contractor or really an employee. You can issue a 1099 and still have the worker treated as your employee — with their pay charged to your comp policy.
What the test looks at
Most tests weigh how much control and independence the worker really has. Common factors:
- Behavioral control — do you direct how, when, and where the work is done, or just the result?
- Financial independence — do they have their own business, tools, insurance, and other clients? Can they make a profit or loss?
- Relationship — is it project-based with a contract, or ongoing and exclusive like a job?
No single factor decides it; the overall picture does. Some states use stricter versions (like an “ABC test”) that make it even harder to classify someone as independent.
Two ways misclassification costs you
- State reclassification — a labor or comp agency rules your “sub” was an employee, triggering back premium, taxes, and penalties.
- Audit add-back — even a genuine sub gets folded into your payroll if they can’t document their own coverage. More on 1099 subs and your audit →
What a genuine subcontractor looks like
- Has their own business entity, tools, and other customers.
- Works under a signed contract, invoices you, and controls their own methods.
- Carries their own workers’ comp coverage or a valid exemption.
Even a real sub needs documentation
Being a true independent contractor keeps you out of the reclassification problem — but it’s the certificate that keeps them off your audit. Collect a COI with a workers’ comp line (or an exemption) for the dates they worked. Check each sub now →

Frequently asked questions
Does a 1099 make someone a subcontractor for workers’ comp?
No. A 1099 is a tax form. Workers’ comp and labor agencies apply their own control and independence tests, and can treat a “1099 sub” as your employee.
What decides if a worker is an employee or a subcontractor?
How much control and independence they have — who directs the work, whether they run their own business with their own tools, clients, and insurance, and whether the relationship is project-based or ongoing.
What happens if I misclassify an employee as a subcontractor?
A state can reclassify them, triggering back premium, taxes, and penalties. Separately, an undocumented sub’s pay can be added to your payroll at audit.
