How Long You Have to File an Injury or Workers’ Comp Claim in Missouri

TL;DR: If you were hurt in Missouri, you likely still have time. Most workers comp claims, including car crashes, carry a five-year deadline under RSMo § 516.120. Workers’ compensation is shorter at two years, with a separate 30-day notice step. Miss the deadline and a court can dismiss even a strong case.

If you were hurt weeks or months ago and you’re wondering whether it’s too late, the answer is usually no. Most Missouri injury claims give you five years, and workers’ compensation gives you two. The deadline matters because once it passes, the court can throw the case out no matter how badly you were hurt or how clearly someone else was at fault.

The short version: Missouri’s deadlines at a glance 

Missouri sets different filing deadlines depending on the type of claim. The five-year rule for personal injury is one of the more generous in the country, but several claim types run much shorter, and those are the ones that catch people off guard.

Varies by entity

 

Two points deserve emphasis. Workers’ comp has a hidden trap: beyond the two-year filing window in § 287.430, you also have to give your employer written notice of the injury within 30 days under § 287.420. Verbal notice does not satisfy the statute. And if a government body is involved, the clock can shrink dramatically, so those cases need attention fast.

When the clock actually starts 

For most injuries, the deadline starts the day the injury happens. That works cleanly for a car crash or a slip and fall accident where you feel it immediately.

Some injuries don’t announce themselves that way. A back problem that develops over months, a repetitive-strain condition, or internal damage you don’t notice at first can complicate the start date. In those situations, Missouri generally measures the clock from when you knew, or reasonably should have known, that you were hurt and that the injury was connected to the incident or to your work.

For workers’ comp specifically, occupational diseases and repetitive-trauma injuries carry their own timing. Under § 287.420, the 30-day notice period for those conditions runs from the diagnosis, or from when the work connection becomes reasonably apparent, rather than from a single accident date. If your situation involves a slow-developing injury, don’t assume the deadline has passed. Get it confirmed.

Five mistakes that burn your deadline 

The deadline rarely gets missed on purpose. It gets missed through small assumptions that turn out to be wrong.

  1. Treating the insurance claim and the lawsuit deadline as the same thing. Reporting a crash to an insurer does not stop the legal clock. Only a properly filed claim or lawsuit does that.
  2. Waiting until treatment is finished before calling a personal injury lawyer. Evidence fades, witnesses move, and footage gets overwritten. You can start protecting the claim while you’re still recovering.
  3. Skipping written notice on a work injury. A conversation with your supervisor feels like enough. Under § 287.420, it isn’t. Put it in writing, keep a copy, and do it within 30 days.
  4. Not realizing a government defendant changes everything. A crash involving a city bus or a county vehicle can carry a short notice window, sometimes measured in weeks. Missing it can bar the claim even inside the five-year period.
  5. Assuming the five-year rule covers your case. It covers most, though wrongful death, medical malpractice, and workers’ comp all run shorter. The wrong assumption here is expensive.

Where a Missouri injury lawsuit gets filed

Where your case gets filed depends largely on where the injury happened. Missouri civil cases are generally brought in the county where the incident occurred or where the defendant is located, and that shapes which courthouse hears your claim.

For the communities we serve, that usually means one of three places:

 

Venue rules have exceptions, and cases involving multiple parties or locations can get complicated. The practical takeaway is simpler: the details of where and how you were hurt affect both your deadline and where your case belongs, which is one more reason to have someone review the specifics early.

Missouri personal injury claim deadlines FAQs

How long do I have to file a car accident claim in Missouri?

Generally five years from the date of the crash under RSMo § 516.120. That covers most auto injury claims, though a claim involving a government vehicle can carry a much shorter notice deadline.

What is the statute of limitations for workers’ comp in Missouri?

Two years from the date of injury to file a claim with the Division of Workers’ Compensation under RSMo § 287.430, and you must also give your employer written notice within 30 days under § 287.420. If your employer never filed a report of injury, the filing window can extend to three years.

What happens if I miss the deadline to file an injury claim?

The other side can ask the court to dismiss the case, and Missouri courts routinely grant those motions. Once the deadline passes, the strength of your evidence usually no longer matters, so acting before the clock runs out is what preserves your right to recover.

Does the deadline start on the accident date or when I found out I was hurt?

For most injuries it starts on the date of the injury. When an injury isn’t apparent right away, Missouri generally measures the clock from when you knew, or reasonably should have known, that you were hurt and that the harm was connected to the incident or your work.

Is the deadline different if I’m suing a city or a government agency?

Yes. Claims against a city, county, or state agency fall under the Missouri Tort Claims Act and often require written notice on a much shorter timeline, sometimes as little as 90 days. These cases need prompt attention.
