OSHA 300A Posting Requirements and 2026 Penalty Updates: What Employers Need to Know
It’s time once again to focus on an important requirement from the Occupational Safety and Health Administration (OSHA). Employers with 10 or more employees are required to post the OSHA 300A Summary of Work-Related Injuries and Illnesses from February 1 through April 30, 2026. This annual posting reflects injury and illness data from calendar year 2025 and ensures transparency for employees regarding workplace safety performance. If you need guidance in completing the OSHA 300A form, we’ve got resources to help you out. We partnered with Keevily Spero & Whitelaw to create a webinar that walks you through the steps for both the OSHA 300 and 300A forms. You can find the webinar on our YouTube Channel or watch the video below. In addition to posting, many employers are required to electronically submit their OSHA 300A data by March 2, 2026. Let’s break this down. OSHA 300A Form – Posting Requirements The OSHA 300A form summarizes the injury and illness data recorded throughout the year on the OSHA 300 Log. It provides totals for: Total cases Cases with days away from work Cases with job transfer or restriction Recordable injuries and illnesses by category Total number of days away or restricted Establishment information and annual average employment Covered employers must ensure that the 300 Log is completed as the year progresses and that totals are accurately calculated at year-end for the 300A summary. The OSHA 300A must: Be certified by a company executive Be posted in a conspicuous location where employee notices are normally placed Remain posted from February 1 through April 30 Be retained for five years Be updated if new recordable information becomes available Electronic Submission – March 2, 2026 Deadline OSHA’s electronic reporting rule requires certain establishments to submit injury and illness data through the OSHA Injury Tracking Application
