OSHA 300A Reporting: Tips for Correctly Classifying an Incident 
Get Your Quote!

The deadline to submit OSHA form 300A is March 2, 2026, for companies with 250 or more workers (or fewer, depending on industry).

Managing OSHA recordkeeping is no longer just an internal administrative task. As of 2024’s rule changes, it’s become a matter of public transparency.  

OSHA’s latest updates have significantly expanded electronic reporting requirements, meaning your Form 300A, 300, and 301 data may now be subject to federal scrutiny and public disclosure. 

One of the most common issues employers have with form 300A data is determining whether an incident is recordable, or whether it falls under simple first aid.  

This can be one of the biggest mistakes employers can make when it comes to injury & incident reporting. 

To help you navigate these changes, we’ve updated our guide with the latest OSHA rules and guidelines that safety managers should use to ensure your logs remain airtight. 

Let’s break it down.

Who is Required to Submit OSHA 300A Electronically?

 

Under the 2024 Final Rule, the requirements for electronic submission via the Injury Tracking Application (ITA) have shifted. While many companies have always submitted the 300A Summary, the scope has expanded to include more detailed data for certain employers. 

* Establishments with 20–249 employees in specific high-hazard industries (listed in Appendix A) must submit Form 300A. 

* Establishments with 250+ employees in any industry required to keep records must submit Form 300A. 

* The 100+ Employee Rule: As of 2024, establishments with 100 or more employees in “highest-hazard” industries (listed in Appendix B) must now submit not just the 300A Summary, but also case-specific data from Forms 300 and 301. 

 

What Is a Recordable Injury vs. First Aid?

 

The most common mistake in OSHA reporting is over-reporting minor incidents. You should only record incidents that meet the “General Recording Criteria.” An incident is recordable if it results in: 

* Death. 

* Days away from work. 

* Restricted work or transfer to another job. 

* Medical treatment beyond first aid. 

* Loss of consciousness. 

* A significant injury or illness diagnosed by a licensed healthcare professional. 

Critical Update: OSHA maintains a specific, exhaustive list of “First Aid” treatments. These include using non-prescription medications at non-prescription strength, cleaning wounds, or using finger guards. If the treatment is on that list, it is not recordable, regardless of who provides the care. 

 

How to Calculate Annual Average Number of Employees and Total Hours Worked?

 

To complete your Form 300A, you need two specific numbers that often cause confusion: 

* Annual Average Employment: Add the number of employees paid in every pay period (including part-time, temporary, and seasonal) and divide by the number of pay periods in the year. 

* Total Hours Worked: Include all hours actually worked by all employees. Do not include vacation, sick leave, or holidays, even if they were paid. If you do not track exact hours for salaried staff, you may use a reasonable estimate. 

 

OSHA 300A Posting Requirements for 2025 Data

 

Even if you submit your data electronically, you must still physically post the 300A Summary in your workplace. 

* Dates: The form must be posted from February 1 to April 30, 2026.  

* Location: In a conspicuous place where notices to employees are customarily posted (e.g., a break room or near a time clock). 

* Certification: It must be signed by a “Company Executive” (e.g., Owner, Officer, or Highest-Ranking Official at the site) to certify that the data is accurate. 

 

How to Protect Employee Privacy in Electronic Submissions?

 

With the new requirement for certain industries to submit Form 300 and 301 data, privacy is a major concern. OSHA’s ITA system is designed to remove names, but the burden is on the employer to ensure “Personally Identifiable Information” (PII) is not included in the description fields. 

What to exclude: Names, Social Security numbers, home addresses, and names of physicians. 

What to include: Job title, date of birth (which OSHA converts to age upon submission), and gender. 

 

Relevant OSHA Updates

 

1. The “High-Hazard” Expansion 

OSHA recently updated the NAICS codes used to determine which industries must report. Even if you were exempt in the past, you’ll need to check out the updated Appendix A and Appendix B.

Many manufacturing, transportation, and retail sectors have been reclassified into higher-risk categories, triggering new electronic reporting obligations. 

 

2. Public Data Exposure 

OSHA now posts establishment-specific injury and illness data on a public-facing website. This transparency aims to allow employees and the public to identify the safest workplaces. 

However, it also means that errors on your 300 Log are now visible to competitors, labor unions, and regulators. 

 

3. Penalty and Fines 

Failure to post the 300A or failing to submit data to the ITA by the March 2 deadline can result in significant fines, which are now adjusted annually for inflation. 

 

Final Tips for Accuracy

 

– Seven-Day Rule: You must enter a recordable case on your Form 300 Log within seven calendar days of receiving information that the incident occurred. 

– Count Calendar Days: When recording “Days Away” or “Job Transfer/Restriction,” count calendar days, not just workdays. This includes weekends and holidays. 

– Cap the Count: You can stop counting days away or restricted once the total reaches 180 days for a single case.

As the March 2 deadline approaches, make sure your paperwork is in order and filed appropriately. If not, you might find yourself facing additional penalties and punishments from OSHA.

File before the deadline with the tips above, remain in compliance, and avoid any potential problems.

Stay safe, stay compliant, and let’s keep our workplaces incident-free!
