OSHA 300A: 2026 Posting and ITA Reporting Deadlines Explained
If your company maintains OSHA injury records, the annual OSHA 300A deadline is one of the most important compliance dates on your calendar.
Every year, covered employers must prepare and post OSHA Form 300A, and some establishments must electronically submit injury and illness data through OSHA’s Injury Tracking Application (ITA).
Missing either requirement can create compliance issues.
This guide explains what OSHA 300A is, how it differs from the OSHA 300 log, who must comply, and the deadlines employers need to know for 2026.
What Is OSHA 300A?
OSHA Form 300A is the annual summary of work-related injuries and illnesses.
It summarizes information from your OSHA 300 log, which is the detailed running log of individual workplace injury and illness cases.
The difference between OSHA 300 and 300A is simple:
- OSHA 300 Log = ongoing record of individual cases
- OSHA 300A = annual summary of totals from the log
OSHA provides official recordkeeping forms and instructions here: OSHA Recordkeeping Forms
OSHA requires covered employers to post the 300A summary even if there were zero recordable injuries.
That surprises many employers.
OSHA 300A Posting Deadlines for 2026
For 2026 compliance (covering 2025 injury data):
February 1 through April 30, 2026
Covered employers must post OSHA Form 300A at each establishment.
Requirements include:
- Complete the annual summary
- Certify it with a company executive
- Post it where employee notices are normally displayed
- Keep it posted through April 30
If you have multiple locations, posting typically applies at each establishment.
Who Must Post OSHA 300A?
Most employers subject to OSHA recordkeeping rules must post OSHA 300A.
However, some employers may be partially exempt.
Exemptions are often based on:
- Company size
- Industry classification (NAICS)
Employers should verify exemption status carefully.
Do not assume your business is exempt.
OSHA maintains an exemption reference table here: OSHA Exempt Industries Table
This helps determine whether your business falls under partial recordkeeping exemptions.
Who Must Submit Through OSHA ITA?
Some employers must electronically submit data through OSHA’s Injury Tracking Application (ITA).
ITA deadline for 2026:
March 2, 2026
Electronic reporting requirements depend on:
- Establishment size
- Industry classification
- Federal reporting category
Important: OSHA often evaluates reporting requirements based on establishment headcount, not total company headcount.
Employers can confirm requirements through OSHA’s ITA Coverage Application here: ITA Coverage Application
OSHA also provides a general overview of injury reporting requirements here: OSHA Injury Reporting Overview
If electronic submission applies, submit directly through OSHA’s Injury Tracking Application here: OSHA Injury Tracking Application
What May Need to Be Submitted?
Depending on your classification, you may need to submit:
- OSHA 300A summary data
- OSHA 300 log data
- OSHA Form 301 incident reports
Some industries have expanded reporting obligations under OSHA’s designated industry requirements.
OSHA lists those covered industries in Appendix B here: OSHA Appendix B Designated Industries
Common OSHA 300A Mistakes
Many employers make avoidable mistakes.
Common issues include:
Assuming zero incidents means no posting
Covered employers often still must post.
Using total company size instead of establishment size
This creates reporting errors.
Missing executive certification
Form 300A must be certified before posting.
Waiting too long to verify ITA requirements
Late planning creates rushed submissions.
Posting at only one location
Multi-site employers often need establishment-level posting.
OSHA Recordkeeping Training Helps Reduce Errors
Recordkeeping mistakes can affect compliance, inspections, and internal reporting.
Good OSHA recordkeeping training helps employers:
- Classify incidents correctly
- Maintain accurate OSHA 300 logs
- Prepare annual summaries properly
- Understand ITA requirements
