Jay explains

Montana has no state or local sales tax, and nothing stands in its place; a few resort areas levy a local tax on lodging and restaurants. A company that ticked Montana as a state where it collects sales tax has no state return to file there.

Next dates

No fixed date. It appears on a calendar under "No fixed date" so it is not forgotten.

Your company's compliance calendar

Three answers to start. Refine it after.

An LLC's tax treatment decides which federal return it files. Choose the line that matches yours. Nonprofits are covered too.
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.
More about the company: other states, payroll, dates, abroad

Each one adds that state's registration, employer and tax filings. A state where you only keep inventory or make sales belongs under sales tax states below, not here.
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.
States where you collect sales tax

Needed for states that key filings to the anniversary of formation.
Some taxes start at a revenue threshold.
Outside the United States
Each adds the FinCEN or IRS form that comes with it: the FBAR, Form 5472, Form 5471, Forms 1042 and 1042-S.

No account needed. Nothing is stored until you save it.
