In Missouri, calling a worker a 1099 independent contractor does not decide whether you need workers comp for them. What matters is how much you actually control the work: a worker you direct and control like an employee can be treated as one under the law, no matter what the paperwork says. Lawyers call this the right-of-control test. The label on the invoice is not what the state looks at.
Who this is for: Missouri owners who pay workers as 1099 contractors and want to know whether those workers still count toward coverage and expose them to risk.
The short version
- Whether a worker counts comes down to how much you control their work, not the label on the invoice.
- A 1099 label does not settle it; a misclassified worker can count as an employee.
- Misclassified workers can push you over the five-employee line, or trigger the one-employee construction rule.
- In construction, you can be responsible for an uninsured subcontractor's injured workers.
- Getting proof of coverage from every subcontractor is how you protect yourself.
How Missouri decides who is really an employee
Missouri weighs a set of factors from long-standing case law to decide who is really an employee. No single factor controls; the state looks at the overall picture of how much say you have over the work.
| Factor | Points toward employee | Points toward contractor |
|---|---|---|
| Control over the work | You direct how and when it is done | The worker controls the methods |
| Tools and workplace | You supply them | The worker supplies their own |
| Independent business | Works mainly for you | Runs a distinct business serving many clients |
| Payment | Paid by the hour or a regular wage | Paid by the job or project |
| Part of your regular business | Does your core work | Does a separate, specialized task |
Construction: the up-the-ladder rule
Construction has an extra layer. When you hire a subcontractor to do work that is part of your usual business, Missouri can treat you as the statutory employer of that subcontractor's employees. If the subcontractor carries its own workers comp, you are off the hook. But if the subcontractor is uninsured and one of its workers is hurt, the responsibility can climb the ladder to you. That single rule is why general contractors insist on a certificate of insurance from every sub before work starts, and it is the cheapest protection you can get.
An electrical-sub example
Illustrative, not a quote. A general contractor in Kansas City brings on a two-person electrical crew as a 1099 subcontractor. The electricians set their own hours, supply their own tools, and work for many builders, so they look like genuine contractors. Still, the general contractor asks for proof that the electrical firm carries its own workers comp. When one electrician is injured, the electrical firm's policy handles the claim, and the general contractor is not pulled in. Without that proof, the general contractor could have become responsible for the injury. See our workers comp for electricians page.
Real questions Missouri owners ask
Do I need workers comp for 1099 contractors in Missouri?
It depends on whether they are really contractors. Missouri uses a right-of-control test, so a worker you direct like an employee counts toward your coverage even if you pay them on a 1099.
Does calling someone a 1099 contractor settle it in Missouri?
No. The label does not decide status. Missouri looks at how much control you have over the work, who supplies the tools, how the person is paid, and whether they run their own business.
Can misclassified contractors trigger a coverage requirement?
Yes. If workers you treat as 1099 are really employees, they count toward the five-employee threshold, or trigger the one-employee rule in construction, and you may owe coverage you thought you avoided.
Am I liable for an uninsured subcontractor's injured worker?
In construction, you can be. If a subcontractor doing your usual work is uninsured and one of its workers is hurt, the responsibility can climb up to you as the statutory employer. Proof of the sub's coverage prevents that.
How do I protect myself when using subcontractors?
Get a current certificate of insurance from every subcontractor before work starts, confirming they carry their own workers comp. That is the simplest way to keep an uninsured sub's claim from becoming your problem.
How does Missouri decide if my worker is really a contractor?
Missouri weighs a set of factors its courts have long used: how much control you have over the work, who furnishes the tools, how the person is paid, the skill involved, and whether the work is part of your regular business. No single factor decides it.
Does a one-person subcontractor need workers comp?
A solo subcontractor with no employees may not be required to carry it, but general contractors often require a policy anyway. A one-person policy that assumes no payroll, sometimes called a ghost policy, can satisfy that.
Why Missouri owners choose Morrow
- We shop the right market for you. In Missouri you buy workers' comp on the open, competitive market from any private insurer licensed in the state, because Missouri has no state fund after Missouri Employers Mutual became a fully private company in 2025, and if no private carrier will take you, the insurer-of-last-resort pool run by NCCI and serviced by Travelers is the guaranteed backstop, so we can shop your rate freely and still have a fallback for hard-to-place work.
- We catch pricing mistakes. Your price depends heavily on the category your work falls into for pricing (the class code). Put people in the wrong category and you overpay for years. We review your payroll and classifications before you buy.
- Proof of coverage, fast. Need a certificate (proof of coverage) for a general contractor or a landlord before Monday? We turn those around the same business day for most carriers.
- We help lower the score that drives your price. Insurers give you a score based on your past claims that raises or lowers your cost (the experience modification rate). We review it each year, flag errors, and connect you with return-to-work and safety resources that bring it down.
- Real people when a claim happens. When someone gets hurt, we stay involved through the life of the claim, not just at renewal.
