OSHA injury reporting is more than filling out paperwork after an accident. This guide explains who must keep OSHA 300, 300A, and 301 forms, what counts as a recordable injury, and how employers can complete the forms correctly.
Workplace injury record keeping is one of those responsibilities that often gets attention only after an incident happens. But by then, the stakes are already high. A missed entry, a misunderstood exemption, or a late report can create compliance problems on top of an already difficult situation.
That is why OSHA injury reporting matters so much. Good record keeping helps employers stay compliant, identify recurring hazards, and show that safety issues are being taken seriously. It also gives managers better data to improve training, procedures, and corrective actions over time.
For many companies, the confusion starts with a simple question: do we even need to keep OSHA injury and illness records? From there, the next questions come quickly. Which injuries are recordable? Which events must be reported directly to OSHA? How do the OSHA 300, 300A, and 301 forms work together?
This guide breaks down the essentials of OSHA injury reporting so employers can understand their obligations and complete the forms correctly.
Step 1: Determine Whether Your Company Must Keep OSHA Injury Reporting Forms
Not every employer is required to routinely keep OSHA Forms 300, 300A, and 301. Under OSHA’s recordkeeping rule, many employers with more than 10 employees must keep these records unless their establishment falls into a partially exempt industry category. OSHA bases the small-employer exemption on the size of the entire company, not just one location. If the company had 10 or fewer employees at all times during the previous calendar year, it is generally exempt from routinely keeping these forms unless OSHA or the Bureau of Labor Statistics specifically requires it in writing.
Industry classification also matters. Some low-hazard industries are partially exempt from routinely maintaining OSHA injury and illness records, even if they have more than 10 employees. OSHA maintains a list of those partially exempt industries by NAICS code.
However, there is an important catch: even employers that are partially exempt from keeping routine records still must report severe work-related incidents to OSHA. That means an exemption from maintaining the log does not automatically mean an exemption from all OSHA injury reporting obligations.
Step 2: Understand the Difference Between Recording and Reporting
This is where many employers get confused. Recording and reporting are not the same thing.
Recording means entering a qualifying work-related injury or illness on OSHA Forms 300 and 301, then summarizing annual totals on Form 300A if your company is required to keep those records.
Reporting means directly notifying OSHA when a work-related fatality, in-patient hospitalization, amputation, or loss of an eye occurs. All employers covered by the OSH Act must do this, even if they are otherwise exempt from maintaining routine records. A fatality must be reported within 8 hours. An in-patient hospitalization, amputation, or loss of an eye must be reported within 24 hours.
In other words, OSHA injury reporting can refer to more than one responsibility. Employers may need to record an incident on the OSHA log, report a severe event directly to OSHA, electronically submit annual data, or all three, depending on the circumstances.
Step 3: Know What Requires OSHA Injury Reporting
If your company is required to keep records, not every first-aid case belongs on the log. OSHA’s general recording criteria say a work-related injury or illness is recordable if it results in any of the following:
-
death
-
days away from work
-
restricted work or job transfer
-
medical treatment beyond first aid
-
loss of consciousness
-
a significant injury or illness diagnosed by a physician or other licensed healthcare professional
That last point is important. Some injuries are recordable even if they do not involve lost time. For example, certain diagnosed conditions such as a fractured bone, a punctured eardrum, cancer, or a chronic irreversible disease may still be recordable.
One of the most misunderstood parts of OSHA injury reporting is the line between first aid and medical treatment beyond first aid. OSHA says diagnostic procedures alone, observation, counseling, and listed first-aid measures generally do not make a case recordable. But once treatment goes beyond first aid, the case may become recordable if it is work-related and a new case.
Step 4: Learn the Purpose of Each Form
Employers who must maintain records need to understand how the three core forms work together.
OSHA Form 300
This is the Log of Work-Related Injuries and Illnesses. It is the running log used to classify each recordable case. Employers enter the employee’s information, describe the case, and mark whether it involved death, days away from work, job transfer or restriction, or another recordable outcome.
OSHA Form 301
This is the Injury and Illness Incident Report. It provides the more detailed incident-level documentation behind each case entered on the OSHA 300 log. It includes details about what happened, when it happened, and what harm occurred.
OSHA Form 300A
This is the Summary of Work-Related Injuries and Illnesses. It is the year-end summary created from the OSHA 300 log totals. Even if no recordable injuries occurred during the year, employers who are required to keep records must still complete and certify the 300A summary, then post it in a visible location from February 1 through April 30 of the following year.
Understanding the role of each form is essential to accurate OSHA injury reporting.
Step 5: Complete the Forms Properly
Proper completion starts with timing and consistency.
When a recordable incident occurs, the employer should first determine whether it is work-related, whether it is a new case, and whether it meets OSHA’s recording criteria. If the answer is yes, the case should be entered on the OSHA 300 log and documented on Form 301. The employer should classify the outcome correctly, especially when deciding between days away, restricted duty, or other recordable cases. OSHA’s tutorial and form package provide official instructions for how each column should be completed.
At the end of the calendar year, totals from the 300 log are transferred to Form 300A. A company executive must certify that the summary is accurate and complete before posting. OSHA requires the 300A posting to remain up through April 30.
Another key point in OSHA injury reporting is electronic submission. OSHA says only certain establishments must electronically submit information through the Injury Tracking Application. For 2026 submissions, OSHA notes that data submission began January 2, 2026, and covered establishments must submit by March 2. Some establishments must submit only Form 300A data, while certain larger establishments in designated high-hazard industries must also submit data from Forms 300 and 301.
Common Mistakes Employers Should Avoid
A few errors show up again and again in OSHA injury reporting:
First, employers sometimes assume that because they are small or in a lower-risk industry, they never have to interact with OSHA recordkeeping rules. That is not true when a severe injury must be reported directly to OSHA.
Second, some companies record workers’ compensation claims and OSHA recordables as though they are the same thing. They are not always the same, and OSHA recordability must be evaluated under OSHA’s criteria.
Third, employers often mishandle first-aid cases versus medical treatment beyond first aid. That can lead to both under-recording and over-recording.
Fourth, many organizations miss the annual 300A posting window or fail to ensure proper executive certification.
Why Good Injury Record Keeping Matters
Done correctly, workplace injury record keeping is more than a compliance exercise. It reveals trends, highlights recurring hazards, and gives safety leaders the evidence they need to improve programs and procedures. When records are accurate, employers are better positioned to target corrective actions, defend decisions, and show a serious commitment to worker safety.
At its core, OSHA injury reporting is about visibility. You cannot fix what you do not track. Employers that understand when the forms apply, what makes a case recordable, and how to complete each form correctly are in a much better position to reduce both compliance risk and workplace injuries.
If your organization has multiple facilities, rotating supervision, paper-based forms, or inconsistent incident documentation, now is a good time to review your process. A standardized system for incident capture, classification, and record retention can make OSHA injury reporting far easier and far more reliable.
