Don’t toss that 2024 Form 300a, Annual Summary of Work-Related Injuries and Illnesses! While April 30, 2025, was the last day California employers needed to post the previous year’s summary of work-related injuries and illnesses, employers still must retain their 2024 Form 300, Form 300a and Forms 301 for five years following the end of the calendar year these records cover. So, employers can toss any pre-2019 records.
Every year, from February 1 to April 30, California employers must post their annual summary of work-related injuries and illnesses that occurred during the previous calendar year in a visible and easily accessible area at each worksite — even if no workplace injuries occurred. Employers also must record all job-related injuries and illnesses on the Form 300, Log of Work-Related Injuries and Illnesses as well as record the incident on the Form 301, Injury and Illness Incident Report.
On May 1, employers can take down their Form 300a, but they can’t just file and forget about it. During the five-year recordkeeping period, employers must update their Form 300 with any newly discovered recordable injuries and illnesses.
Even if employers electronically report their Form 300a data to the federal Occupational Safety and Health Administration (OSHA), they still must keep and maintain their Form 300, Form 300A and Forms 301 for five years.
Plus, if requested, employers must provide employees, former employees and their properly authorized personnel representatives with copies of the Form 300 (with all personal identifying information deleted unless under certain circumstances) and current or archived Forms 300a by the end of the next business day.
Remember, it’s unlawful for an employer to terminate or discriminate against an employee for requesting access to an occupational injury or illness report.
