Finalizing Your OSHA Log for 2025: What You Need to Know

Written by Unison Risk Advisors | Dec 16, 2025 5:06:25 PM

Each year, employers subject to OSHA’s recordkeeping requirements must ensure their injury and illness logs are accurate and ready for certification. Proper recordkeeping is a critical step in maintaining transparency and reducing risk.

Under OSHA’s Recordkeeping Standard, three key forms are required:

  • OSHA Form 300 – Log of Work-Related Injuries and Illnesses
  • OSHA Form 301 – Incident Report
  • OSHA Form 300A – Annual Summary

Steps to Finalize Your OSHA Log

1. Update All Records Promptly

Every recordable injury or illness must be logged within seven calendar days of receiving information about the case. Review your Form 300 and Form 301 for completeness and accuracy. Common mistakes include failing to separate establishments or not updating logs when new details emerge.

2. Verify Work-Relatedness and Classification

Ensure each case meets OSHA’s definition of work-related and is correctly categorized (e.g., days away from work, restricted duty). Misclassification can lead to compliance issues and inaccurate Days Away, Restricted or Transferred (DART) rates.

3. Prepare the Form 300A Annual Summary

Aggregate totals from your Form 300 and complete the 300A summary. This form must be certified by a company executive before posting in a visible location from February 1 through April 30.

4. Confirm Electronic Submission Requirements

Establishments with 100 or more employees in designated high-hazard industries must electronically submit detailed case data from Forms 300 and 301, along with the 300A summary, via OSHA’s Injury Tracking Application (ITA). The deadline for submission is March 2, 2026 for 2025 data.
