Missouri workers’ compensation pays for medical treatment and replaces part of your wages when you’re hurt on the job, no matter who caused the accident. The program is run by the Division of Workers’ Compensation inside the Department of Labor and Industrial Relations, and it covers most private-sector employees once their employer has at least five workers.1Missouri Department of Labor and Industrial Relations. Division of Workers’ Compensation Wage benefits are set at two-thirds of your average weekly earnings and are not taxed, but you lose the right to collect them if you miss a notice deadline or if your injury fails Missouri’s causation test.
Which Employers Have to Carry It
Any Missouri employer with five or more workers must carry workers’ compensation insurance. Full-time, part-time, and seasonal workers all count toward that total.2Missouri Department of Labor and Industrial Relations. Workers’ Compensation Insurance Construction is different: one employee triggers the requirement.3Missouri Revisor of Statutes. Missouri Code 287.030 – Employer Defined Corporate officers and LLC members count toward the employee threshold, though LLC members can elect out. Sole proprietors and partners don’t count.
An employer who knowingly goes without coverage commits a class A misdemeanor and can be fined three times the premium they would have paid, or $50,000, whichever is more. A second offense is a class E felony.4Missouri Revisor of Statutes. Missouri Code 287.128 – Penalties for Failure to Insure If you’re injured working for an uninsured employer, you can still file a claim with the Division, and the employer loses most of the defenses it would normally have.
One boundary matters here: workers’ compensation only covers employees. Independent contractors are not covered, and the actual working relationship controls, not whatever label appears in a contract. If an employer calls you a contractor to avoid buying insurance, you may still be an employee under the law, and the employer can face the same penalties as one who refused to buy coverage at all.5U.S. Department of Labor.

What Counts as a Covered Injury
Your injury has to arise out of and happen in the course of your employment. The accident must be tied to your job duties, not to a personal risk you’d face anywhere.6Missouri Revisor of Statutes. Missouri Code 287.020 – Definitions Missouri uses a “prevailing factor” standard, meaning the workplace accident must be the primary cause of your medical condition, outweighing every other contributing factor. It’s a tougher test than many states apply, and it’s why a lot of Missouri claims get denied.
Occupational diseases qualify on the same terms. Carpal tunnel and other repetitive-motion injuries, along with illnesses from long-term chemical or dust exposure, are covered when the job exposure was the prevailing factor.7Missouri Revisor of Statutes. Missouri Code 287.067 – Occupational Disease Defined Workers with pre-existing conditions that contributed to a repetitive-motion injury have a harder time clearing that bar.
What Isn’t Covered
Commuting injuries are excluded by statute. The ride between home and your employer’s main workplace isn’t covered, even if you were driving a company vehicle at the time.8Missouri Revisor of Statutes. Missouri Code 287.020 – Definitions The old “extension of premises” theory is gone, so an injury on a sidewalk, parking lot, or road leading to your workplace generally isn’t covered unless the employer owns or controls that property. Injuries from hazards you’d face in everyday life, unrelated to the job, are also out.
Reductions for Safety Violations and Intoxication
Benefits can be cut if you caused your own injury. Ignoring a required safety device or a reasonable written safety rule drops your benefits by 25 to 50 percent, but only if the employer can prove the rule was written, that you knew about it, and that the company had actually enforced it before your accident. Using alcohol or non-prescribed controlled substances in violation of an employer’s drug-free workplace policy cuts benefits in half. If intoxication was the direct cause of the injury, benefits are forfeited entirely.9Missouri Revisor of Statutes. Missouri Code 287.120 – Compensation, Amount
What You Can Collect
Missouri provides four categories of benefits: medical care, temporary disability payments, permanent disability payments, and death benefits for dependents. Wage-replacement benefits are paid at two-thirds (66⅔%) of your average weekly earnings at the time of injury, capped at a maximum reset each fiscal year.10Missouri Department of Labor and Industrial Relations. Benefits Available
Medical Care
The insurer must pay for all reasonable and necessary treatment related to your work injury. That covers surgery, prescriptions, physical therapy, prosthetics, and mileage to authorized appointments. There is no dollar cap, and treatment continues as long as it’s necessary. The important catch: your employer or its insurer picks your treating doctor. You can see your own doctor, but you pay for it unless the insurer agrees to the switch. A provider you weren’t authorized to see cannot bill you directly once they’ve received written notice that this is a workers’ compensation case.11Missouri Department of Labor and Industrial Relations. Get Medical Care
Temporary Total Disability
Temporary total disability pays 66⅔% of your average weekly wage while you’re completely unable to work, up to the statutory maximum. The state average weekly wage used to set that maximum for the fiscal year running July 1, 2025 through June 30, 2026 is $1,219.85.12Missouri Department of Labor and Industrial Relations. State Average Weekly Wage Payments don’t start right away. There’s a three-business-day waiting period, and the insurer only pays you for those three days retroactively if your disability lasts more than 14 days.10Missouri Department of Labor and Industrial Relations. Benefits Available TTD continues until you return to work or reach maximum medical improvement.
Permanent Partial Disability
If you recover but have a lasting impairment, permanent partial disability (PPD) kicks in. Missouri uses a schedule that assigns a specific number of weeks of compensation to each body part. A hand, arm, foot, or leg each carries its own set figure. For injuries that affect the body as a whole, a doctor assigns a percentage rating, and that percentage drives the calculation. PPD is paid weekly, though lump-sum settlements are common.
Permanent Total Disability
When an injury leaves you permanently unable to work, permanent total disability pays for life at the 66⅔% rate, capped at 105% of the state average weekly wage as of your injury date. The minimum is $40 a week. Payments are suspended if you recover enough to go back to your old job or an equivalent one.13Missouri Revisor of Statutes. Missouri Code 287.200 – Permanent Total Disability
Death Benefits
If a work injury kills an employee, the employer pays funeral costs and weekly benefits to the worker’s dependents at 66⅔% of the deceased employee’s average weekly earnings, again capped at 105% of the state average weekly wage. A surviving spouse receives benefits until death or remarriage. On remarriage, the spouse gets a lump sum equal to two years of benefits, and the weekly payments stop. Dependent children receive benefits until 18, or until 22 if they’re full-time students at an accredited school. Children unable to earn a living because of a physical or mental disability keep receiving benefits past those cutoffs.14Missouri Revisor of Statutes. Missouri Code 287.240 – Death Benefits
How to File
Filing involves two separate steps: giving notice to your employer, and, if necessary, filing a formal claim with the Division. Many cases are resolved after the insurer accepts the claim, and the formal filing only comes into play when something is disputed.
Notify Your Employer Within 30 Days
You must give your employer written notice within 30 days of the accident, stating the time, place, and nature of your injury along with your name and address.15Missouri Revisor of Statutes. Missouri Code 287.420 – Written Notice of Injury For occupational diseases and repetitive-motion injuries, the 30-day clock starts on the date a doctor diagnoses the condition, not the date you were first exposed. Missing the deadline doesn’t automatically end your claim, but you’d have to show the delay didn’t hurt the employer. Report right away if you can.
Once the employer knows, the employer or its insurer has to file a First Report of Injury with the Division electronically within 30 days.16Missouri Department of Labor and Industrial Relations. Employer Refuses to File Injury Report If your employer refuses, contact the Division directly. The failure actually helps you: it extends your deadline for filing a formal claim from two years to three.17Missouri Revisor of Statutes. Missouri Code 287.430 – Time Limitation for Filing Claims
File a Claim If the Insurer Won’t Pay
If the insurer denies the claim, disputes the benefits owed, or stops paying, file a Claim for Compensation (Form WC-21) with the Division. That opens a contested case before an administrative law judge who can decide the dispute.18Missouri Department of Labor and Industrial Relations. File a Claim The form asks for your personal information, the date of injury, your gross wages, the zip code where the accident happened, and a description of your injuries. You have to sign it yourself unless an attorney is handling it.
The deadline is two years from the date of injury, the date of death, or the last workers’ compensation payment made on your behalf, whichever is later. It stretches to three years if your employer never filed the First Report of Injury.17Missouri Revisor of Statutes. Missouri Code 287.430 – Time Limitation for Filing Claims For occupational diseases, the clock doesn’t start until the condition is reasonably discoverable.
If Your Claim Is Disputed
Missouri has several ways to resolve disagreements, scaling up in formality. The Division’s Dispute Management Unit offers voluntary mediation by phone, often before any formal paperwork is filed. If that fails, either side can request a conference before an administrative law judge, which can happen even without a formal Claim for Compensation on file.19Missouri Department of Labor and Industrial Relations. Resolve Your Case
After a formal claim is filed, the case can move to a pre-hearing to narrow the issues, then to a more structured mediation with an administrative law judge. If that doesn’t settle things, the case goes to a final hearing, which is a full evidentiary proceeding with sworn testimony. The judge then issues a written award. Conferences, pre-hearings, and mediations are generally scheduled within 120 days of the request.19Missouri Department of Labor and Industrial Relations. Resolve Your Case
If you need help immediately while the dispute drags on, request a hardship hearing. It’s available when you haven’t yet reached maximum medical improvement, need medical treatment, or should be getting TTD benefits that the employer has cut off. The judge can issue a temporary or partial award to keep benefits moving.19Missouri Department of Labor and Industrial Relations. Resolve Your Case
Attorney Fees
Attorney fees in Missouri workers’ compensation cases are capped at 25% of the benefits recovered, and the administrative law judge has to approve the fee. Most workers’ compensation attorneys take cases on contingency, so you pay nothing upfront and the fee comes out of whatever you recover. Given how often the prevailing-factor test comes up in denials, it’s worth talking to an attorney whenever the insurer pushes back on causation or disputes your disability rating.
The Second Injury Fund
The Second Injury Fund exists to add compensation when a new workplace injury combines with a pre-existing disability to leave a worker substantially more impaired than the new injury alone would have. The current employer is only on the hook for the piece attributable to the recent accident; the fund covers the gap.20Missouri Revisor of Statutes. Missouri Code 287.220 – Second Injury Fund
Changes effective January 1, 2014 sharply narrowed the fund. Permanent partial disability claims against the fund are barred for injuries after that date. Only permanent total disability claims qualify, and only when the worker has a documented pre-existing disability equal to at least 50 weeks of PPD compensation that falls into one of these categories:
- A disability caused directly by active duty in the U.S. Armed Forces.
- A disability from an earlier workplace injury that was itself covered by workers’ compensation.
- A pre-existing condition that, while not itself a compensable injury, directly and significantly worsened the subsequent work injury.
- Loss of one eye, ear, or extremity followed by a compensable injury to the opposite eye, ear, or extremity.
Workers employed in sheltered workshops can also qualify under a separate provision. The fund won’t pay if you’ve filed a workers’ compensation claim in another state for the same injury.20Missouri Revisor of Statutes. Missouri Code 287.220 – Second Injury Fund
Taxes, Your Job, and Medicare
Workers’ compensation benefits are fully exempt from federal income tax, and Missouri doesn’t tax them either. The exemption covers TTD, PPD, PTD, and death benefits.21Office of the Law Revision Counsel. 26 USC 104 – Compensation for Injuries or Sickness If you also receive Social Security Disability Insurance, federal law caps the combined total at 80% of your pre-disability earnings. Anything over that threshold is taken out of your SSDI, not your workers’ compensation. The way a lump-sum workers’ compensation settlement is written can change how that offset is calculated, which matters if you depend on both.
Missouri workers’ compensation law does not hold your job open while you recover. The federal Family and Medical Leave Act does, giving eligible employees up to 12 weeks of unpaid, job-protected leave for a serious health condition, which most work injuries qualify as. You’re eligible if your employer has at least 50 employees within 75 miles of your worksite, you’ve worked there at least 12 months, and you’ve logged at least 1,250 hours in the past year. FMLA leave usually runs at the same time as your workers’ compensation absence, so the 12-week clock may be ticking while you’re collecting TTD. Your group health insurance has to continue during the leave, and you’re entitled to return to your same position or an equivalent one when it ends.
If you’re already on Medicare, or expect to enroll within 30 months of settling your claim, future medical costs for your work injury have to be set aside through a Workers’ Compensation Medicare Set-Aside Arrangement. The arrangement protects Medicare from paying for care that your settlement should cover. The Centers for Medicare and Medicaid Services reviews set-aside proposals when the claimant is already on Medicare and the settlement exceeds $25,000, or when Medicare enrollment is expected within 30 months and the settlement exceeds $250,000.22Centers for Medicare & Medicaid Services. Workers’ Compensation Medicare Set Aside Arrangements Getting it wrong can cost you Medicare coverage for the injury later, so older workers and anyone with long-term injury expectations should raise this before signing a settlement.
