OSHA Form 300A: 2026 Posting and ITA Reporting Deadlines (What Employers Must Do)

OSHA Form 300A: 2026 Posting and ITA Reporting Deadlines (What Employers Must Do)

PCS
January 24, 2026•5 min read

Two annual OSHA recordkeeping deadlines come up fast each year: posting your Form 300A summary and, for some employers, submitting injury and illness data electronically through OSHA’s Injury Tracking Application (ITA).

This guide breaks down what to do, who is typically covered, and how to confirm your requirements.

Key deadlines for 2026 (2025 data)

  • Feb 1 through Apr 30, 2026: Post OSHA Form 300A (Summary of Work-Related Injuries and Illnesses).

  • March 2, 2026: Some establishments must submit 2025 data electronically through OSHA’s Injury Tracking Application (ITA).

Step 1: Confirm you must post Form 300A

Form 300A is the annual summary that must be posted during the February to April posting window for employers covered by OSHA recordkeeping rules. Posting may still be required even if you had zero recordable incidents in 2025.

What to do

  1. Complete Form 300A for the 2025 calendar year.

  2. Have it certified by a company executive.

  3. Post it at each establishment in a location where employee notices are typically placed.

  4. Keep it posted Feb 1 through Apr 30, 2026.

Partial exemptions: know before you assume

Some employers are partially exempt from routine OSHA recordkeeping based on:

  • Size, and/or

  • Industry classification (low-hazard NAICS categories)

If you are unsure, use these official resources:

Step 2: Determine if you must submit electronically through the ITA

Some establishments must submit data electronically through OSHA’s ITA. In many cases, requirements are based on the size of each establishment, not your total company headcount across locations.

Start here:

Electronic submission: what may be required

Depending on your establishment size and industry, you may need to submit:

  • Form 300A data, and for some covered employers,

  • Form 300 (Log) and Form 301 (Incident Report) data

Helpful references:

State Plan note

Many State Plan employers still use the ITA, but requirements can vary. Confirm whether your state has any additional requirements:

Quick coverage check: 5 questions to answer in 10 minutes

Use this quick list before you assume you are covered or exempt:

  1. How many employees did each establishment have in the prior calendar year?

  2. Are you partially exempt due to low-hazard NAICS or size?

  3. Do you meet electronic submission criteria for Form 300A?

  4. Are you in a designated industry that may require Form 300 and 301 submission?

  5. Are you covered by a State Plan, and if so, are there added requirements?

Common mistakes that create compliance risk

These are the issues that most often cause confusion or missed steps:

  • Using total company headcount instead of establishment headcount

  • Posting at only one site when you have multiple establishments

  • Missing executive certification before posting

  • Assuming “no incidents” means “no posting”

  • Waiting until late February to set up ITA access and confirm requirements

Simple action checklist and timeline

This week

  • Assign an internal owner (HR, Safety, Operations, or a shared owner)

  • Confirm establishment headcounts and NAICS classification

  • Verify whether you are partially exempt or covered

Before Feb 1

  • Finalize Form 300A

  • Get executive certification

  • Confirm posting locations at each establishment

Early February

  • Confirm whether electronic submission is required via the ITA Coverage Application

  • Set up ITA access and confirm who will submit

Late February

  • Review data for accuracy and completeness

  • Prepare submissions and internal approvals

By March 2

FAQ

Do we still post Form 300A if we had zero recordables in 2025?

Many covered employers must still complete and post Form 300A even if there were zero recordable incidents.

What counts as an “establishment”?

An establishment is typically a single physical location where business is conducted. Electronic reporting requirements often use establishment headcount, not total company headcount.

What does “partially exempt” mean?

Some employers are exempt from routine recordkeeping based on size or low-hazard industry classification, but certain serious incident reporting obligations can still apply.

How do State Plans affect submission?

State Plans often align with federal requirements, but some states add or modify requirements. Check your State Plan guidance if applicable.

If we have multiple locations, do we post at each one?

In most cases, posting is handled at each establishment location where employee notices are normally posted.

Recap and next step

  • Post Form 300A Feb 1 through Apr 30, 2026

  • Submit required data through the ITA by March 2, 2026 (as applicable)
