OSHA Form 300A: The Annual Summary, Posting and Electronic Submission

Short answer: the 300A is the one-page year-end summary of your OSHA 300 log. A company executive certifies it, and you post it from February 1 to April 30, even if the year had no recordable cases. Separately, establishments with 20–249 employees in designated industries, and all record-keeping establishments with 250 or more, must submit their 300A data to OSHA’s Injury Tracking Application by March 2; establishments with 100 or more in a second list of industries also submit their 300 and 301 data. Checked against 29 CFR 1904.32 and 1904.41 on eCFR and OSHA’s ITA page on October 10, 2026.

1. What the 300A is

Form 300A is the Summary of Work-Related Injuries and Illnesses (29 CFR 1904.29(a)). It is one page of totals from your OSHA 300 log for the calendar year. 29 CFR 1904.32(a) sets four steps at the end of each year:

1. review the 300 log to verify the entries are complete and accurate, and correct any deficiencies;
2. create the annual summary;
3. certify it; and
4. post it.

Completing it means totalling the log’s columns, entering zeros if you had no recordable cases, and entering the calendar year, the company name, the establishment name and address, the annual average number of employees covered by the log and the total hours worked by them (1904.32(b)(2)(i)–(ii)). If you use an equivalent form instead of OSHA’s 300A, it “must also include the employee access and employer penalty statements found on the OSHA 300-A Summary form” (1904.32(b)(2)(iii)). OSHA’s forms page adds that equivalent 300As must also be certified and posted.

2. Who certifies it

A company executive must certify that he or she has examined the 300 log and “reasonably believes, based on his or her knowledge of the process by which the information was recorded, that the annual summary is correct and complete” (1904.32(b)(3)). Under 1904.32(b)(4) the executive must be one of:

• an owner of the company (only if it is a sole proprietorship or partnership);
• an officer of the corporation;
• the highest ranking company official working at the establishment; or
• the immediate supervisor of the highest ranking company official working at the establishment.

A safety coordinator or office manager can prepare the summary, but unless they fit one of those four, they cannot sign it.

3. Posting: February 1 to April 30

“You must post the summary no later than February 1 of the year following the year covered by the records and keep the posting in place until April 30” (1904.32(b)(6)). It goes up in each establishment, “in a conspicuous place or places where notices to employees are customarily posted”, and you must make sure it is not altered, defaced or covered by other material (1904.32(b)(5)). A year with no recordable cases still gets a summary: the rule tells you to enter zeros.

So the summary covering calendar year 2026 goes up by February 1, 2027 and stays up through April 30, 2027.

4. Electronic submission to OSHA (ITA)

Posting is for your employees. Some establishments must also send the data to OSHA each year through the Injury Tracking Application (ITA). The rule is 29 CFR 1904.41. We read it on eCFR on October 10, 2026; eCFR’s history shows 1904.41 last changed in 2024, when the July 21, 2023 rule (88 FR 47346) took effect. There are three routine categories, all measured per establishment on peak employment during the previous calendar year:

• Deadline: March 2 of the year after the calendar year the forms cover (1904.41(c)). For 2026 data, that is March 2, 2027. OSHA’s ITA page says submissions open January 2, that the deadline for 2025 data was March 2, 2026, and that establishments which missed the deadline must still submit and can do so until December 31.
• Everyone counts. Part-time, seasonal and temporary workers each count as one employee (1904.41(b)(2)).
• Partially exempt employers do not routinely submit (1904.41(b)(6)), unless OSHA tells them in writing to (1904.41(a)(3)).
• State Plan states are included (1904.41(b)(7)). OSHA’s ITA page tells establishments under State Plan jurisdiction to contact their State Plan directly.
• EIN. Each submitting establishment must provide the Employer Identification Number it uses (1904.41(a)(4)).
• Names stay off. For 300 and 301 data you leave out the employee name, the employee’s address, the name of the physician or other health care professional, and the treatment facility name and address (1904.41(b)(9)).
• How. OSHA’s ITA offers a web form, a CSV upload, or an API. OSHA does not accept paper forms by mail or forms by email.

Appendix A to Subpart E lists whole sectors (agriculture, forestry, fishing and hunting; utilities; construction; manufacturing; wholesale trade) and specific industry groups, among them grocery stores (4451), general freight trucking (4841), warehousing and storage (4931), general medical and surgical hospitals (6221), nursing care facilities (6231), traveler accommodation (7211) and drycleaning and laundry services (8123). Use the full appendix, or OSHA’s ITA Coverage Application, to check your own code.

5. How SDSentry handles the 300A

In SDSentry, a company admin records each case on the Injury log tab against the location where it belongs: the 300 Log columns (date, employee name and job title or a privacy-case flag, where it happened, the injury and body part, the classification, days away and days restricted, and the injury or illness type) and every Form 301 field (the employee’s address, date of birth, date hired and sex; the physician or other health care professional and treatment facility; the emergency room and overnight in-patient questions; the time work began and the time of the event; what the employee was doing, what happened, the injury and the object or substance; date of death; and who completed the report). Each SDSentry location is one establishment, so it prints a Form 300 log and a 300A summary per establishment and calendar year, and a 301 incident report for each case, each as a printable page laid out as an equivalent form under 29 CFR 1904.29(b)(4) that you can save as a PDF. A case can be edited in place, and every change is recorded in the account’s audit log.

The 300A page SDSentry prints is for one establishment and one calendar year. It totals that establishment’s cases for you: deaths, cases with days away, cases with job transfer or restriction, other recordable cases, total days away, total days restricted, and the six injury and illness types. It carries the establishment information block (company name, establishment name, street, city, state and ZIP, industry description, NAICS code, annual average number of employees and total hours worked), the employee access and employer penalty statements that 1904.32(b)(2)(iii) requires on an equivalent form, and the certification block with the company executive’s name, title, phone and date and a signature line. You enter the establishment details, the employee count and the hours once per establishment and year on the Injury log tab; anything left blank prints as a blank to fill in by hand, and the page warns you on screen before you print.

The company executive still has to sign it, and you still post the signed copy from February 1 to April 30. SDSentry does not submit to OSHA’s ITA; if your establishment is covered, type the same totals into the ITA web form yourself before March 2.
