Mississippi Workers' Compensation: How Quickly Must an Accident Be Reported?

Reporting Deadlines in Mississippi

Mississippi law requires an employee to inform their employer of a work‑related injury or illness within 30 days of the incident. The employer then has 30 days to file a claim with the Mississippi Workers' Compensation Commission (MWCC). Missing either deadline can jeopardize the employee's right to benefits, though a late filing may be allowed if the employee can show a reasonable cause for the delay.

Employee's Obligation: 30‑Day Notice

The employee's first step is to give written notice to the employer as soon as possible, but no later than 30 days after the accident. The notice should include the date of injury, a description of how it happened, and any medical treatment received. If the employee fails to give this notice, the employer can argue that the claim is barred, and the MWCC may deny benefits unless the employee proves the delay was due to a legitimate reason, such as lack of knowledge of the injury's work‑related nature.

Employer's Obligation: 30‑Day Claim Filing

After receiving the employee's notice, the employer must complete and submit the workers' compensation claim form (Form WC‑100) to the MWCC within 30 days. The employer's filing includes details about the employee, the injury, and the employer's insurance information. Failure to meet this deadline can result in penalties for the employer and may shift the burden of proof to the employee to demonstrate that the injury is compensable.

Exceptions and Extensions

Both parties can request an extension of the reporting period, but the request must be supported by a documented reason, such as delayed medical diagnosis or the employee's inability to report due to incapacitation. The MWCC evaluates extensions case‑by‑case and may grant additional time if the circumstances are compelling.

Consequences of Late Reporting

If an employee misses the 30‑day notice, the MWCC may still consider the claim if the employee can prove the delay was reasonable. Common acceptable reasons include:

• Delayed onset of symptoms that made the injury's work‑related cause unclear.
• Medical advice to wait for a diagnosis before reporting.
• Incapacity to communicate due to severe injury.

Without a satisfactory explanation, the claim is likely to be denied, and the employee may lose entitlement to medical benefits, wage replacement, and other compensation.
