Jay explains

Montana requires every corporation registered in the state to file an annual report with the Montana Secretary of State by April 15 each year. The fee is $20. Miss it and the result is $15 late fee; involuntary dissolution after December 1. A company registered in more than one state files this in each of them.

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.

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

Date of formation

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