The Fine Print Behind OSHA’s 10-Employee Recordkeeping Rule

Every employer assumes OSHA recordkeeping applies to them. Most of the time, that assumption is correct. But not always, and getting it wrong in either direction creates real problems.

Some employers spend hours each year maintaining OSHA 300 logs, 300A summaries, and 301 incident reports when they are not actually required to. Others assume they are exempt and stop tracking injuries altogether, only to discover during an audit or inspection that they were wrong all along.

Understanding where your organization actually stands is a five-minute exercise. Skipping it can cost far more than that.

Two Exemptions, Not One

OSHA recordkeeping requirements generally apply to employers with more than 10 employees. If your organization has 10 or fewer employees at any point during the year, you are typically exempt from maintaining the 300 log, the 300A summary, and the 301 incident report.

That is the first exemption. The second is easy to overlook because it has nothing to do with company size.

Certain low-hazard industries are exempt from these recordkeeping requirements regardless of how many employees they have. Finance, insurance, and real estate are common examples. An organization in one of these industries with 500 employees may still be exempt, simply because the industry itself is classified as low risk for the kinds of injuries OSHA tracks.

This is where employers get tripped up. A growing company may assume that crossing the 10-employee threshold automatically triggers recordkeeping obligations, without checking whether its industry classification already exempts it. Or an employer in a low-hazard industry may assume that exemption is permanent, without recognizing that OSHA can require any exempt establishment to begin recording if requested in writing.

Exemption Does Not Mean Immunity

Here is the detail that catches employers off guard. Even fully exempt organizations must still report serious incidents.

Fatalities, in-patient hospitalizations, amputations, and losses of an eye must be reported to OSHA regardless of company size or industry exemption. The recordkeeping exemption covers the day-to-day logs. It does not cover the most serious events.

This distinction matters because an employer who assumes total exemption may fail to report a serious incident within the required window, not out of negligence, but out of a misunderstanding of what the exemption actually covers. A fatality still requires notification within eight hours. An in-patient hospitalization, amputation, or loss of an eye still requires notification within 24 hours. Those clocks do not stop just because your organization is small or classified as low hazard.

Why This Matters Beyond Compliance

Confirming your recordkeeping status is not just a compliance exercise. It shapes how you think about your data.

If your organization is required to maintain OSHA logs, that data becomes a valuable input for your workers’ compensation metrics. Total hours worked, recordable incidents, and lost-time cases feed directly into calculations like cost per FTE and your recordable incident rate. Employers who are required to track this information already have much of what they need to measure program performance without duplicating effort. The OSHA 300A summary, which you are filing anyway, becomes a source of data your workers’ compensation program can use for free.

If your organization is exempt, that does not mean the underlying goal disappears. Preventing injuries, controlling claim costs, and protecting employees still matter regardless of what OSHA requires you to document. Exempt employers can still choose to track the same categories of data internally, simply because doing so produces better decisions. A small business owner does not need a government mandate to benefit from knowing how many days employees lose to injury each year.

A Practical Next Step

Confirm your status before assuming either direction. Check your current employee count against the 10-employee threshold, counting the highest number of employees you had at any point during the previous calendar year, not just your current headcount. Check your industry classification against OSHA’s published list of partially exempt industries, since the exemption is tied to specific NAICS codes rather than a general sense of what counts as low hazard.

If you learn you are required to maintain records and have not been doing so consistently, address that now rather than waiting for an inspection to reveal the gap. Build the habit into your existing HR or safety workflow so it does not become a scramble every February. If you learn you are exempt, decide intentionally whether you still want to track this data internally to support your broader workers’ compensation program, rather than assuming exemption means the topic no longer deserves attention.

Either way, the goal is the same. Know where you actually stand, rather than operating on an assumption that may not hold up the day it matters most.
