Who needs workers’ comp in Missouri?
Missouri generally requires employers with five or more employees to carry workers’ compensation insurance. Construction industry employers must carry coverage with one or more employees. Family members working for the business are typically considered employees. Out-of-state employers with staff working in Missouri must comply with Missouri law and show Missouri correctly on the policy.
Sole proprietors and partners are usually not covered unless they elect to be included. Corporate officers and LLC members are typically considered employees; some owners may be able to exclude themselves if they meet statutory criteria and complete the required election, subject to state rules and program underwriting.
Using 1099s doesn’t control status. Employment is based on control and the nature of the work. Prime/general contractors can be responsible for benefits owed to employees of uninsured subcontractors. Always collect COIs from subs and verify endorsements.
What does Missouri workers’ comp cover?
- Medical care for work-related injuries/illnesses
- Wage replacement during lost time (subject to state limits)
- Temporary and permanent disability benefits
- Vocational rehabilitation when eligible
- Death benefits for eligible dependents
In Missouri, employers typically have the right to select the authorized treating physician. State fee schedules, utilization review, and authorization rules can apply—your adjuster will confirm what’s required.
Unique to Missouri: construction 1+ and employer-directed care
– Construction employers must carry coverage with one or more employees—no 5-employee threshold.

Who chooses the doctor?
Missouri generally allows the employer to select the authorized treating physician. Unauthorized treatment may not be compensable. Your adjuster will outline approved providers and required preauthorizations.

Not automatically. If the relationship meets Missouri’s employment tests, a contractor may be deemed an employee. Prime/general contractors can be liable for uninsured subs. Require COIs from subs and verify endorsements.

Does Missouri use NCCI and Experience Mods?
Yes. Missouri follows NCCI for classifications and Experience Mods. Accurate class coding and audit prep help control premiums.
What posting or notice requirements apply?
Post the Missouri workers’ compensation notice and claims reporting information in a conspicuous place. Provide written instructions to injured employees on reporting and access to care.
What if I’m declined—are assigned risk or PEO options available?
Yes. Missouri participates in the NCCI Assigned Risk Plan for employers unable to obtain standard coverage. Professional Employer Organizations (PEOs) may also be available depending on industry and underwriting.
How do premium audits work?
Most policies are audited annually at term end. Be ready with payroll reports and quarterly filings, overtime details, subcontractor COIs, job descriptions by class code, and owner/officer inclusion or exclusion forms.
Multi-state employees — how should I set up my policy?
Ensure Missouri is listed properly on your policy (3.A/3.C) when employees live in or regularly work in MO. We configure multi-state coverage so it follows your people.
What is a “ghost policy” in Missouri?
A minimal workers’ comp policy (often excluding owners) used to obtain a COI when there’s little or no payroll. Suitability depends on contract terms and state rules—ask us for compliant options.

Often, yes—subject to program approval and contract specifics. Request early to confirm availability, pricing, and any restrictions.
