You can file a workers' compensation claim online in Missouri through the Division of Workers' Compensation portal at labor.mo.gov. The online system allows injured workers to submit a Claim for Compensation electronically without mailing paper forms. To complete your online submission, you will need your injury date and description, your employer's name and address, and any available medical documentation. Once submitted, you will receive a confirmation number to track your claim's status.
How to File a Workers' Comp Claim Online in Missouri
Missouri's Division of Workers' Compensation (DWC) provides an online filing option through its official portal at labor.mo.gov. This digital submission system allows injured workers to initiate a formal Claim for Compensation without visiting a DWC office or mailing a paper WC-21 form.
Step 1: Access the DWC Online Portal
Go to labor.mo.gov and navigate to the Division of Workers' Compensation section. Look for the option to file a Claim for Compensation online. The portal may allow you to create an account to manage your filing or proceed as a guest for a one-time submission. Creating an account gives you the ability to log back in and check the status of your claim after submission.
Step 2: Gather the Required Information
Before you begin the online submission, collect the following:
- Date of injury — The exact date your workplace injury or illness occurred
- Description of the injury — How the injury happened and what body parts are affected
- Employer information — Your employer's legal name, address, and workers' compensation insurance carrier if known
- Medical documentation — Any treatment records, diagnoses, or doctor's notes you have received
- Your personal information — Name, address, Social Security number, and contact details
Step 3: Complete and Submit the Form
Fill out the online Claim for Compensation form completely and accurately. Incomplete or inconsistent information can delay processing. Once you submit, save your confirmation number — this is your proof of filing and allows you to track the status of your claim through the portal.

Online Filing vs. Paper Filing: What You Should Know
Filing your Missouri workers' comp claim online offers several practical advantages over mailing a paper form, but it also comes with considerations worth understanding before you begin.
Advantages of Online Filing
- Faster submission — Electronic filing reaches the DWC immediately, with no mailing delays or lost documents
- Instant confirmation — You receive a confirmation number the moment your digital claim is accepted, creating a clear record of when you filed
- Status tracking — Online accounts allow you to monitor your claim's progress without calling the DWC
- Reduced paperwork errors — The system may flag missing required fields before you submit, reducing the chance of rejection for incomplete forms
Potential Technical Issues
If you encounter technical difficulties with the online portal — browser incompatibility, session timeouts, or upload errors — try a different browser or clear your cache before reattempting. If the portal is unavailable, the paper WC-21 form remains an alternative. You can also contact the DWC directly at 573-751-4231 for assistance.

Frequently Asked Questions
Can I file a workers' compensation claim entirely online in Missouri without mailing anything?
Yes. Missouri's Division of Workers' Compensation accepts Claim for Compensation submissions through its online portal at labor.mo.gov. You can complete and submit the entire claim electronically without printing or mailing any forms. Once submitted, you will receive a digital confirmation number as proof of filing. Keep this number in a safe place — it is your primary reference for tracking your claim's status and verifying when it was received by the DWC.
What is the deadline to file a workers' comp claim online in Missouri?
Missouri law generally requires you to file a Claim for Compensation within two years of your date of injury. If your employer or its insurer provided any medical treatment or wage benefits, the deadline extends to two years from the date of the last benefit payment. Filing online does not change this statute of limitations — it applies equally to paper and electronic submissions. Because this deadline is strict and missing it can permanently bar your claim, you should file as soon as your injury is documented and report it to your employer immediately.
Do I need an attorney to file a workers' comp claim online in Missouri?
You are not required to have an attorney to file your initial online claim, but having one significantly improves your chances of receiving the full benefits you are owed. Insurance companies review every claim looking for reasons to reduce or deny payment. An experienced workers' compensation attorney can help you accurately document your injury, gather medical evidence, and respond to insurer challenges. At The Bruning Law Firm, we offer free consultations and work on a contingency fee basis, meaning there is no cost to you unless we recover compensation on your behalf.
