Missouri Workers’ Comp Requirements at a Glance
Here are the exact Missouri workers compensation requirements every employer should know:
| Employees that trigger the mandate | 5 |
| Which workers count | All workers count toward the 5-employee threshold including full-time, part-time, seasonal, and casual laborers; LLC members and corporate officers also count; sole proprietors and partners do not count; construction employers must carry coverage with 1 or more employees; agricultural employers must carry coverage with 10 or more employees |
| Who is exempt | Sole proprietors, partners, farm and agricultural laborers (employers with fewer than 10 agricultural workers), domestic servants in a private home, occasional household labor, qualified real estate agents operating as independent contractors, direct sellers, unpaid volunteers of 501(c)(3) or 501(c)(19) organizations, sports officials and adjudicators for interscholastic or amateur youth programs who are not paid employees, and commercial motor-carrier owner-operators |
| Owners & officers | Sole proprietors and partners are automatically excluded but may elect in; LLC members may exclude themselves by filing a Missouri LLC Member Rejection of Coverage Form; corporate officers generally cannot exclude themselves unless the company has no more than 2 owners who are the only employees; in construction, an S-Corporation with no more than 2 owner-employees can withdraw from coverage by notifying the Division of Workers Compensation per RSMo 287.090.5 |
| Penalty for going without | Civil penalty of up to 3 times the annual premium or up to 50000 whichever is greater; first criminal offense is a Class A misdemeanor punishable by up to 1 year in jail and a fine up to 2000; subsequent offenses are a Class E felony punishable by up to 4 years in prison and a fine up to 10000; the employer is personally liable for all injury costs and injured workers may file claims with the Missouri Uninsured Employers Fund which pays benefits and seeks reimbursement from the uninsured employer |
| Monopolistic state? | No — buy from private carriers |
| State fund | Missouri Employers Mutual (MEM) is a competitive state fund created in 1993 as an independent public corporation and is the largest workers comp insurer in the state; it is not a monopolistic fund and employers may choose MEM or any licensed private carrier; Missouri also allows self-insurance for qualified large employers through the Division of Workers Compensation |
How to Get Workers’ Comp Coverage in Missouri
Missouri employers may purchase workers compensation coverage from any licensed private insurance carrier, from the competitive state fund Missouri Employers Mutual (MEM), or through self-insurance if approved by the Division of Workers Compensation; employers unable to obtain coverage in the voluntary market may access the assigned-risk pool

What Workers’ Comp Covers in Missouri
Workers’ compensation is a no-fault system: an injured employee gets benefits without having to prove the employer did anything wrong, and in exchange gives up the right to sue for most workplace injuries. A typical Missouri policy pays for medical treatment tied to a work injury, part of the wages lost while the worker recovers, longer-term disability benefits if the injury is permanent, and death benefits to a family.
It also includes employers-liability coverage, which protects the business if an injury still leads to a lawsuit. That trade-off is the practical heart of the Missouri workers compensation requirements: the coverage exists to keep one bad injury from sinking both the worker and the business.
Employees vs. Independent Contractors in Missouri
The most common way owners get the Missouri workers compensation requirements wrong is by assuming a worker is an “independent contractor” who does not count. State agencies look at how the work is actually controlled, not the label on a 1099. If Missouri decides a contractor was really an employee, the business can owe back premiums and penalties as if coverage should have been in place all along.
When you are close to the employee threshold, confirm each worker’s status with your state board before you decide you are exempt.
Other Missouri workers’-comp rules: Missouri applies a strict construction standard to workers comp statutes meaning courts do not construe the law liberally in favor of the injured worker as many other states do; the agricultural employee threshold is 10 which differs from the general threshold of 5 and the construction threshold of 1;
LLC members may freely elect out of coverage while corporate officers generally cannot unless the company has 2 or fewer owner-employees; an S-Corporation in construction with no more than 2 owner-employees can withdraw entirely from the Workers Compensation Law by notifying the DWC under RSMo 287.090.5

Understanding Missouri Workers Compensation Requirements
The Missouri workers compensation requirements exist to make sure injured employees get medical care and lost wages without having to sue. For most owners, the Missouri workers compensation requirements come down to one number: the employee count that triggers the mandate, shown in the table above.
Once you hit that count, Missouri workers compensation requirements apply whether you planned for them or not, and the penalty for going without is real. If any part of the Missouri workers compensation requirements is unclear for your business, your state workers’-comp board can confirm the threshold, the exemptions, and how to get covered.
Next step: Once you know what your business in Missouri actually needs, comparing quotes from several carriers takes only a few minutes. Many owners do this right after they understand their state and trade requirements.
