Jay explains

Beyond posting the summary, some employers submit it electronically by March 2: establishments with 20 to 249 employees in industries on OSHA's designated list, and establishments with 100 or more employees in those industries also submit the detailed 300 and 301 data. If your industry is not on the list and you have fewer than 250 employees, this does not apply.

Your company's compliance calendar

Three answers to start. Refine it after.

What kind of organization is it?

An LLC's tax treatment decides which federal return it files. Choose the line that matches yours. Nonprofits are covered too.

State of formation

Employees

Count everyone on payroll. An S corporation's working owners are employees: they are paid a salary.

Where is it based? The state of the office, or of most of the people

A company based outside its state of formation is registered in both and files in both.

More about the company: other states, payroll, dates, abroad

Company name

Date registered in each other state

Optional. Some states key their report to the day you registered there rather than your date of formation; without it, the formation date stands in and the calendar says so.

Who runs payroll?

Fiscal year ends in

Date of formation

Needed for states that key filings to the anniversary of formation.

Annual revenue

Some taxes start at a revenue threshold.
