Missouri at a Glance
| Required at | 5 employee(s) |
| Which workers count | All employees count toward the 5-employee threshold based on people on payroll (not how many work on a given day), including full-time, part-time, seasonal, casual, and family-member workers; construction-industry employers are required to carry coverage with one or more employees. |
| Who is exempt | Sole proprietors and partners do not count toward the threshold; exempt categories include farm/agricultural labor, domestic servants in a private home, occasional/casual labor for a private household, qualified real estate agents, direct sellers, certain volunteers of 501(c)(3) or 501(c)(19) tax-exempt organizations, and adjudicators/sports officials/contest workers for interscholastic or amateur youth programs. |
| Penalty for going without | Knowingly failing to insure is a Class A misdemeanor plus a civil penalty of up to three times the annual premium the employer would have paid, or up to 50000, whichever is greater; a subsequent violation is a Class E felony (RSMo 287.128). The Division may also pursue injunctive/stop-work relief and the employer faces direct personal liability for injured workers’ losses. |
| Monopolistic state? | No — private carriers |

Missouri Workers’ Comp Requirements at a Glance
Here are the exact Missouri workers comp requirements every employer should know:
| Employees that trigger the mandate | 5 |
| Which workers count | All employees count toward the 5-employee threshold based on people on payroll (not how many work on a given day), including full-time, part-time, seasonal, casual, and family-member workers; construction-industry employers are required to carry coverage with one or more employees. |
| Who is exempt | Sole proprietors and partners do not count toward the threshold; exempt categories include farm/agricultural labor, domestic servants in a private home, occasional/casual labor for a private household, qualified real estate agents, direct sellers, certain volunteers of 501(c)(3) or 501(c)(19) tax-exempt organizations, and adjudicators/sports officials/contest workers for interscholastic or amateur youth programs. |
| Owners & officers | LLC members and corporate officers count as employees toward the threshold by default; Missouri allows them to elect to withdraw/exclude themselves from coverage by filing the appropriate notice of election (Form WC-134) with the Division and their insurer, while sole proprietors and partners are automatically excluded unless they elect in. |
| Penalty for going without | Knowingly failing to insure is a Class A misdemeanor plus a civil penalty of up to three times the annual premium the employer would have paid, or up to 50000, whichever is greater; a subsequent violation is a Class E felony (RSMo 287.128). The Division may also pursue injunctive/stop-work relief and the employer faces direct personal liability for injured workers’ losses. |
| Monopolistic state? | No — buy from private carriers |
| State fund | NONE — Missouri has no state-operated workers’ compensation fund. |
How to Get Workers’ Comp Coverage in Missouri
Missouri employers obtain coverage by buying a policy from a private insurer authorized to write workers’ comp in Missouri, or by qualifying as a self-insurer through the Division of Workers’ Compensation; employers unable to get coverage in the voluntary market can use the assigned-risk pool administered through NCCI.

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.
Employees vs. Independent Contractors in Missouri
The most common way employers get the Missouri workers comp 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’s no-coverage criminal penalty escalates from Class A misdemeanor (first offense) to Class E felony (repeat offense); construction employers are held to the 1-employee standard rather than the general 5-employee rule; the entire Workers’ Compensation Law is codified in RSMo Chapter 287.

Understanding Missouri Workers Comp Requirements
The Missouri workers comp requirements exist so injured employees get care and lost wages without having to sue. For most employers, the Missouri workers comp 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 comp requirements apply whether you planned for them or not, and the penalty for going without is real.
If any part of the Missouri workers comp requirements is unclear, your state board can confirm the threshold, the exemptions, and how to get covered.
