OSHA 300A filing deadline checker

Check whether an establishment should submit OSHA 300A, and whether case-detail data is ready for review. The checker keeps the deadline, records, signer, and filing context together before work moves into a reviewed filing workflow.

Check this deadline Add deadline reminders

Reminder signup saves this filing type and sends deadline prompts before review windows.

Deadline window

March 2 for the prior calendar year's injury-and-illness summary.

Best first step

Run the filing checker with the exact state, what the business does, employee count, and any chemical, food, product, fleet, or entity signals that apply.

Follow-up path

Save deadline reminders, then continue only if the checker result shows a filing that should be reviewed.

Deadline prep

What to gather before the filing window gets close.

Confirm state, what the establishment does, and peak employee count.

Gather OSHA 300 log totals and 300/301 case detail if the 100-employee rule applies.

Assign the signer before March 2 so authorization is not left to deadline week.
