OSHA Record Retention & Update Guides
OSHA records outlive the year they cover. Under 29 CFR 1904.33 you keep the OSHA 300 Log, the privacy case list if you have one, the 300A annual summary and the 301 incident reports for five years following the end of the calendar year the records cover. Records for 2026 are kept through the end of 2031.

Retention is not passive storage. During those five years you must update stored 300 Logs to add newly discovered recordable cases and to show changes in the classification of cases already recorded. If a case's description or outcome changes, remove or line out the original entry and enter the new information; a case that later results in death, for example, moves to column G. You are not required to update the 300A summary or the 301 reports, although you may. When a business changes ownership, the new owner keeps the prior owner's records but does not have to update or correct them (29 CFR 1904.34).
The guides here cover what to keep, amended summaries, corrections after posting or filing, deaths after a recorded injury, and records for establishments that have closed.

Keep the log, the 301s and the 300A in one place
