Arizona Workers Compensation Law: Key Requirements and Employer Obligations

What Sets Arizona Workers Compensation Apart

Arizona mandates that virtually all employers provide workers compensation insurance, regardless of size, with few exemptions such as sole proprietors who do not employ others. The state uses a no‑fault system: injured workers receive medical care and wage replacement without proving employer negligence, while employers gain protection from most lawsuits.

Coverage Thresholds and Exemptions

Any business with one or more employees must carry coverage. The only common exemption is for owners who are the sole employee, unless they elect coverage. Agricultural workers, domestic employees, and certain independent contractors may also be exempt, but misclassification can lead to penalties.

Benefits Provided Under Arizona Law

Benefits fall into three categories: medical treatment, temporary total disability (TTD) wages, and permanent disability (PD) compensation. Medical care is paid in full by the insurer. TTD wages equal two‑thirds of the worker's average weekly wage, up to a statutory maximum, for the period the employee cannot work. PD compensation is calculated using a schedule of injuries or a point system, depending on the injury's nature.

Reporting and Claims Process

Employers must report a work‑related injury to their insurer within eight days of knowledge. The employer also files a First Report of Injury (FROI) with the Arizona Industrial Commission within the same timeframe. The employee must seek medical treatment from a provider authorized by the insurer unless an emergency dictates otherwise.

Employer Responsibilities and Penalties

Beyond securing insurance, employers must maintain a safe workplace, keep accurate injury records, and display the workers compensation notice in a conspicuous area. Failure to comply can result in fines, retroactive insurance assessments, and loss of the employer's right to contest claims.
