OSHA 300 Posting Deadline
What Employers Need to Do Now
OSHA recordkeeping is one of those easy to miss, painful to fix later compliance items. With the OSHA 300 posting deadline approaching, employers should take a few minutes now to confirm what applies, review last year’s log for accuracy, and prepare the annual summary for posting. Below is a quick guide to the OSHA 300/300A requirements, why they matter, and what to do next.
Dates you need to know
What are the OSHA 300 Requirements for 2026?
1. Maintain the required OSHA recordkeeping forms (if you're a covered employer)
OSHA’s recordkeeping system includes:
- Form 300: Log of Work-Related Injuries and Illnesses
- Form 300A: Summary of Work-Related Injuries and Illnesses (annual summary)
- Form 301: Injury and Illness Incident Report
2. Record cases on time
If you’re required to keep records, each recordable injury/illness must be entered on the 300 Log and complete a 301 (or equivalent) within 7 calendar days of learning that a recordable injury or illness occurred.
3. Post OSHA 300A during annual posting window
You must post Form 300A in a conspicuous place where notices are typically posted:
- Post by: February 1, 2026
- Keep posted through: April 30, 2026
This 2026 posting window applies to your 2025 injury/illness summary.
4. Submit Electronically if your establishment is required (OSHA ITA)
Some establishments must submit recordkeeping data electronically using OSHA’s Injury Tracking Application (ITA). OSHA’s ITA guidance confirms:
- Submissions for 2025 data open January 2, 2026
- The due date is March 2, 2026
Submission requirements vary by establishment size and industry. OSHA’s ITA site includes tools and FAQs to help determine whether you’re required to submit and which forms apply (300A only vs. 300/301 also).
5. Keep your records for five years
OSHA recordkeeping forms must be retained for five years (and OSHA expects ongoing accuracy over that period).
6. Remember: serve incident reporting is separate from the log
Regardless of whether you keep a 300 log, all employers must report certain severe incidents to OSHA:
- Fatality: within 8 hours
- In-patient hospitalization, amputation, or loss of an eye: within 24 hours
Why these Requirements Matter
It keeps you compliant and inspection-ready
OSHA recordkeeping has strict timelines and visibility requirements (especially the 300A posting window). Missing a posting or submission deadline can create compliance issues at exactly the wrong time, during an audit, an incident investigation, or a client/contractor review.
It helps you spot trends before they become claims
When your log is accurate and up to date, it becomes a practical safety tool, not just paperwork. Patterns in injuries (tasks, locations, job roles, times of day) often point to correctable hazards, training gaps, or process breakdowns.
It supports better risk outcomes (and often better insurance outcomes)
Clear documentation, faster corrective action, and stronger safety habits typically lead to fewer injuries and fewer costly disruptions, especially for employers with physical operations, driving exposure, or multi-site teams.
