Understanding Workers' Compensation Form 26A: Purpose, How to File, and Common Mistakes

What is Workers' Compensation Form 26A?

Form 26A is a statutory document used in California to report a workplace injury or illness to the Department of Industrial Relations (DIR). It is also known as the "Report of Injury" or "Accident Report." The form initiates the workers' compensation claim process and must be filed by the employer within 30 days of the injury.

Who Must File the Form?

Employers are required to file Form 26A for every employee who sustains a work‑related injury or disease. In most cases, the employer completes and submits the form electronically via the DIR's online portal. Employees who are self‑employed or work in a small business with fewer than 10 employees may file a paper copy, but electronic filing is strongly encouraged for speed and accuracy.

Key Sections of the Form

The form is divided into several sections that capture essential details about the incident, the employee, and the employer. Below is a concise breakdown:

• Section A – Incident Details: Date, time, location, and description of how the injury occurred.
• Section B – Employee Information: Name, address, Social Security number, and job title.
• Section C – Employer Information: Business name, address, and employer identification number (EIN).
• Section D – Injury Details: Body part affected, type of injury, and whether the employee was under the influence of alcohol or drugs.
• Section E – Witnesses: Names and contact information of any witnesses.
• Section F – Medical Treatment: Initial treatment, treating physician, and whether the employee was hospitalized.

When and How to File

Employers must submit Form 26A within 30 days of learning about the injury. The DIR recommends electronic filing through the Industrial Insurance Claims Online System (IICOS). Paper filings can be sent to:

Department of Industrial Relations, Division of Workers' Compensation, 3500 7th St., Los Angeles, CA 90017.

Common Mistakes to Avoid

Even minor errors can delay a claim or lead to denial. Pay close attention to:

• Accurate Dates: The date of injury and filing must be correct.
• Complete Witness List: Missing witness names can raise doubts about the incident.
• Consistent SSN: A mismatch between the employee's SSN on the form and their payroll records triggers a review.
• Proper Signature: The employer's signature must be on the final page; an electronic signature is acceptable if the form is filed online.

What Happens After Filing?

Once the DIR receives the form, it assigns a case number and notifies the employee and the employer. The employee can then seek medical treatment, and the employer's workers' comp insurance will cover related costs. The DIR will review the form for completeness and may request additional information.
