California Employers: Don’t Miss the OSHA 300A Posting and Electronic Submission Deadlines

Compliance with workplace safety reporting is more than a regulatory requirement. It’s a key part of building transparency and trust with your workforce. California employers should be preparing now to meet their annual OSHA Form 300A obligations.

For guidance on complying with California OSHA Form 300A posting and electronic submission requirements, please contact the ILS legal team at contact@consultils.com. We help employers assess compliance obligations and reduce enforcement risk.

What Is Form 300A?

The OSHA Form 300A (https://www.osha.gov/recordkeeping/forms) is a summary of work-related injuries and illnesses recorded during the previous calendar year.

It must include total incidents, the average number of employees, and total hours worked so regulators can calculate incident rates. Even if your workplace had zero recordable injuries, you are still required to complete, certify, and post the form with zeros.

Posting Requirements Start February 1

Employers subject to OSHA recordkeeping rules must post Form 300A in a visible workplace location from February 1 through April 30 each year. If your business operates multiple physical locations, the form must be posted at each site. A company executive must certify the summary before posting.

Some industries are partially exempt from recordkeeping requirements, and businesses with 10 or fewer employees may also qualify for exemption. Employers should confirm their status before assuming they are not covered.

Electronic Submission Deadline: March 2

Certain California establishments must also submit Form 300A data electronically each year by March 2 for the prior calendar year. This requirement applies to:

• Establishments with 250 or more employees, unless specifically exempted under California regulations.

• Establishments with 20–249 employees operating in industries listed in Appendix H of Cal/OSHA’s recordkeeping rules.

  
  

Submissions are completed through the federal OSHA Injury Tracking Application (ITA), which California adopted to align with federal reporting standards.

Why It Matters

California permanently adopted these electronic reporting rules to mirror federal OSHA requirements and strengthen enforcement while reinforcing protections against retaliation for reporting workplace injuries.

Action Steps for Employers

• Confirm whether your business must maintain OSHA injury and illness records.

• Complete and certify Form 300A.

• Post the summary from February 1–April 30.

• Submit the form electronically by March 2 if required.
