Arizona Workers' Compensation Statute of Limitations Explained

Key Deadlines for Arizona Workers' Compensation Claims

In Arizona, a claim must be filed within two years of the injury's date, but the clock can start earlier if the employee gives written notice to the employer within 30 days. For occupational disease claims, the deadline is one year from diagnosis, not from exposure. Missing these limits typically bars recovery, though limited exceptions exist for fraud or undisclosed injuries.

Notice Requirements and Their Impact

Employees must provide a written notice to their employer within 30 days of the injury or discovery of a disease. This notice triggers the employer's duty to report the claim to the State Fund and start the benefits process. Failure to give timely notice does not automatically void the claim, but it can shift the burden of proof to the employee and may lead to reduced benefits.

Exceptions That Can Extend the Period

Arizona law allows extensions in specific situations: if the employer concealed the injury, if the employee was a minor at the time of injury, or if the injury was not discoverable until later (e.g., latent illnesses). Courts may also toll the limitations period for fraudulent concealment or when the employee is incapacitated.
