OSHA ITA Submission Confirmation: What Proof to Keep After Filing
After an ITA submission, save the confirmation, the exact file or data submitted, and the source records behind it, together with the year's 300A packet.

The short version
After an ITA submission, save the confirmation, the exact file or data submitted, and the source records behind it, together with the year's 300A packet. If OSHA asks, you want to show what was filed, when, and by whom.
Submission is not finished until the team can prove what was filed and when.
What you need before you start
Gather these first, and keep them with the record afterward:
- The coverage decision for each establishment: peak headcount, NAICS code, and which appendix applies
- The EIN used by each establishment
- The submitted file or payload and the ITA confirmation
- Notes on any corrections made after submission
The rule behind the steps
Covered establishments submit injury data to OSHA's Injury Tracking Application (ITA) by March 2 each year for the previous calendar year; for 2026 data that is March 2, 2027 (29 CFR 1904.41). Three groups must submit: establishments with 250 or more employees that must keep records (300A data); establishments with 20 to 249 employees in an industry listed in Appendix A to Subpart E (300A data); and establishments with 100 or more employees in an industry listed in Appendix B (300A data plus 300 and 301 case data). Headcount means every individual employed at any time in the prior year, including part-time, seasonal, and temporary workers, and every submission includes the establishment's EIN.
Step by step
- Save the confirmation.
- Save the submitted file.
- Save the validation reports and notes.
- File everything with the 300A support.
Tip: Retain confirmation records, submitted files, source data, and correction notes with the annual packet.
Where this usually goes wrong
Teams celebrate the confirmation screen but do not save reproducible evidence.
Most ITA problems are establishment data problems: an old NAICS code, a parent-company EIN, or a headcount measured at the wrong level. The fix is to decide coverage per establishment in the fall, clean the EIN, NAICS, and address data then, and leave only validation and submission for February.
Analysts see the data after it is entered, so reconciling the log against source documents is where you add the most value.
Special situations
- Rejected rows corrected after upload should be tied back to source records.
- An establishment may use a number or code as its name in the ITA, as long as the submission includes a legal company name.
A worked example
The 2026 folder for each establishment holds the certified 300A, the CSV exactly as uploaded, the ITA confirmation page as a PDF, and a note that one row was rejected for a NAICS typo and resubmitted on February 12.
How it affects the rest of your records
The ITA submission is built from the certified 300A (and, for Appendix B establishments, the 300 and 301), so every correction to the log has to be reconciled with what was submitted.
Where 300log helps
300log validates EIN and NAICS formats, produces ITA-ready CSV files for the 300A and for case data, and can authorize auto-filing of 300A data once you connect an ITA API token.

Frequently asked questions
How can we submit to the ITA?
Through the ITA by entering data in the web form, uploading a CSV file, or sending it through the ITA's API. OSHA publishes CSV and API documentation.
Who has to submit to the OSHA ITA?
Establishments with 250 or more employees that keep records, establishments with 20 to 249 employees in Appendix A industries, and establishments with 100 or more employees in Appendix B industries (which also submit 300 and 301 case data).
When is the ITA deadline for 2026 data?
March 2, 2027.
Do temporary and part-time workers count toward the thresholds?
Yes. Each individual employed in the establishment at any time during the year counts as one employee, including part-time, seasonal, and temporary workers (29 CFR 1904.41(b)(2)).
