OSHA Forms 300, 300A, and 301
How the three recordkeeping forms work together, which employers generally maintain them, and when electronic submission may be required.
Three different functions: Form 300 is the log, Form 301 records incident detail, and Form 300A is the annual summary.
How the forms work together
- Form 300: a running log of recordable work-related injuries and illnesses.
- Form 301: a detailed incident report completed for each recordable case.
- Form 300A: an annual summary derived from the log, certified by a company executive and posted where employee notices are normally displayed.
Who generally keeps records
Many employers with more than 10 employees must maintain OSHA injury and illness records unless a partial industry exemption applies. Separate rules govern severe-event reporting and electronic submission, so exemption from routine recordkeeping should not be treated as exemption from every OSHA reporting duty.
Annual workflow
- Record qualifying cases promptly and maintain supporting Form 301 details.
- Review the log for completeness after year-end.
- Prepare and certify Form 300A.
- Post Form 300A from February 1 through April 30.
- Use OSHA's ITA Coverage Application to determine whether electronic submission is required. The deadline for timely submission of 2025 data was March 2, 2026; missed required submissions still must be filed.
