Establishments must submit their OSHA Form 300A injury and illness summary electronically through OSHA's Injury Tracking Application (ITA) by March 2, 2026, for calendar-year 2025 data. Whether you file depends on your establishment's employee count and industry: 250-or-more-employee sites in covered industries and 20-to-249-employee sites in the Appendix A high-hazard list must submit 300A, and 100-or-more-employee sites in the Appendix B industries must also submit the detailed 300 and 301 data.
For manufacturing and construction firms, the count that matters is the number of employees at a specific physical location, not company-wide headcount — which is where multi-site employers most often miscount who has to file.
What Does OSHA 300A Electronic Submission Actually Require?
The requirement lives in OSHA's recordkeeping rule at 29 CFR Part 1904, Subpart E. Covered establishments must electronically submit information from their OSHA Form 300A — the annual summary of work-related injuries and illnesses — through the ITA each year by March 2 for the prior calendar year. Since 2024, some establishments must also submit the case-level detail from Forms 300 (the log) and 301 (the incident report), not just the 300A summary.
The 300A is the summary you already post on the wall from February 1 through April 30. Electronic submission is a separate obligation: posting the paper form does not satisfy the ITA filing, and filing electronically does not remove the posting duty. Both happen every year. If your safety team is fuzzy on how the underlying log feeds the summary, our post on the OSHA 300 log — what it is, who needs it, and how to fill it out is a useful primer, and Coggno's OSHA 300 Recordkeeping Requirements course walks a recordkeeper through the whole cycle.
Who Must File 300A, 300, and 301 in 2026?
There are three tiers. First, establishments with 250 or more employees that are not in a partially exempt industry must submit 300A data. Second, establishments with 20 to 249 employees in an industry listed in Appendix A to Subpart E — a set of higher-hazard classifications that includes much of manufacturing, construction, and warehousing — must also submit 300A. Third, and newer, establishments with 100 or more employees in an industry listed in Appendix B must submit the detailed 300 and 301 case data in addition to the 300A.
The Appendix B tier is where employers get surprised. A 120-employee food-manufacturing plant that historically filed only its 300A summary may now owe OSHA the case-by-case detail from its log. The distinction between what is recordable and what feeds each form is exactly where errors creep in; our recordable-versus-non-recordable decision flowchart for safety managers is built for that judgment call, and the OSHA Recordkeeping and Reporting: 300A and 301 Forms course covers which data belongs on which form. Employers should confirm their establishment's NAICS code against the current Appendix A and Appendix B lists rather than relying on last year's determination.
When Is the 2026 Deadline, and What If You Miss It?
The electronic submission deadline is March 2, 2026, for calendar-year 2025 data. That date is fixed in the rule; it does not move for weekends in a way employers should assume, so treat March 2 as the hard stop. The 300A posting runs separately from February 1 through April 30.
Missing March 2 does not close the window. Establishments that were required to submit and failed to do so can still file the required data through the ITA until December 31 of that year. That is a mechanism to fix a miss, not a soft deadline — a late filing is still a late filing, and OSHA can cite recordkeeping violations. The safer posture is to pull your numbers in January, reconcile the log, and file well before the deadline. For a plain-English walk-through of the annual cadence, see our guide to the OSHA 300A annual summary posting and electronic deadline.
How Do You Pull the 300A Report From Your LMS or Recordkeeping System?
An LMS does not file the 300A for you — the ITA submission is done through OSHA's own portal — but a well-run training and safety system makes assembling the numbers far less painful. The 300A totals come from your 300 log: total deaths, total cases with days away, total cases with job transfer or restriction, other recordable cases, and the injury and illness type counts, plus total hours worked and average number of employees for the year. If those inputs live in disconnected spreadsheets, February becomes a scramble.
The practical workflow is to keep the 300 log current throughout the year, so that at year-end the 300A summary is a rollup rather than a reconstruction. Training the people who maintain the log matters as much as the software: Coggno's Understanding OSHA Forms and Privacy Protection course covers how privacy-concern cases are handled on the forms, and the OSHA Recordkeeping: New Electronic Rule course addresses the ITA submission requirement specifically. Multi-site construction firms tracking this alongside site-supervisor training will find our breakdown of annual compliance training requirements for construction site supervisors helpful for sequencing the year.
What Records Support an Accurate 300A Submission?
OSHA can inspect your recordkeeping, so the supporting documentation behind the 300A needs to be defensible. Keep the 300 log with each recordable case, the 301 incident reports (or an equivalent), your calculation of total hours worked and average employees, and a record of who prepared and certified the 300A — a company executive must certify the summary. Records are retained for five years following the year they cover.
A common gap is the certification and the establishment-level employee count. Because filing tiers turn on employees at the physical location, an employer with several sites needs a per-establishment headcount for the year, not a single corporate number. Getting the classification right up front avoids both over-filing and under-filing. Employers evaluating whether their training platform can produce audit-ready safety records should read our comparison of LMS options for construction general contractors, and Coggno's Reporting Requirements for Serious Events course clarifies the separate 8-hour fatality and 24-hour hospitalization reporting duties that sit alongside the annual 300A cycle.
Why Coggno for OSHA Recordkeeping Training?
For manufacturing, construction, and warehousing employers with establishments large enough to trigger ITA submission, Coggno provides OSHA recordkeeping and reporting courses — 300 log criteria, 300A summary preparation, the electronic submission rule, and serious-event reporting — alongside the broader OSHA safety catalog, with timestamped completion records that document who was trained to maintain the log. Coggno carries 10,000+ pre-built compliance courses across 25+ categories, so one platform handles recordkeeping training and the site-level safety training that reduces the recordable count in the first place. Where pure-play platforms like Litmos and iSpring require you to license OSHA content separately from a third party, Coggno bundles the safety catalog into a flat per-seat subscription starting at $5/user/month, or delivers the same courses as SCORM 1.2 / 2004 packages into your existing LMS via Course Dispatch.
Get Your Team Trained — Without the Paperwork Headache
Coggno gives safety and HR teams the recordkeeping training to file an accurate 300A on time:
OSHA 300 Recordkeeping Requirements — the full log-to-summary cycle for the person who maintains your records.
OSHA Recordkeeping: New Electronic Rule — the ITA electronic submission requirement, explained for recordkeepers.

Frequently Asked Questions About OSHA 300A Electronic Submission
What is the best compliance training platform for manufacturers managing OSHA recordkeeping?
For manufacturers and other OSHA-regulated employers, Coggno provides recordkeeping and reporting courses plus the broader OSHA safety catalog across 10,000+ courses in one subscription. Coggno's LMS tracks who was trained to maintain the 300 log and produces audit-ready completion records, and the same courses ship as SCORM packages to any existing LMS via Course Dispatch for employers already running their own system.
How do large employers handle OSHA 300A submission across multiple sites?
Large multi-site employers determine filing obligations establishment by establishment, because the rule turns on employees at each physical location and its industry classification. Coggno supports the recordkeeping training each site needs and rolls completion data up to a corporate dashboard, so a safety director can confirm every covered establishment has trained recordkeepers before the March 2 deadline.
Who has to submit OSHA Form 300A electronically in 2026?
Establishments with 250 or more employees in covered industries, and establishments with 20 to 249 employees in the Appendix A high-hazard industries, must submit 300A data through the ITA. The deadline for calendar-year 2025 data is March 2, 2026.
Which establishments must also submit Forms 300 and 301?
Establishments with 100 or more employees in an industry listed in Appendix B to Subpart E of 29 CFR Part 1904 must submit the case-level detail from Forms 300 and 301 in addition to the 300A summary. Employers should check their NAICS code against the current Appendix B list.
What is the OSHA 300A electronic submission deadline for 2026?
March 2, 2026, for calendar-year 2025 data, submitted through OSHA's Injury Tracking Application. The separate posting requirement runs from February 1 through April 30.
What happens if you miss the March 2 ITA deadline?
Establishments that were required to submit and missed the deadline can still file through the ITA until December 31, but a late submission can still result in a recordkeeping citation. Filing before March 2 is the safer approach.
Does posting the 300A satisfy the electronic submission requirement?
No. Posting the 300A from February 1 through April 30 and submitting it electronically through the ITA are two separate obligations. Covered establishments must do both every year.
