Jay explains

New Hampshire has no income tax on wages, but every business organization with gross business income above $109,000, corporations, LLCs and sole proprietorships alike, files the business profits tax, and those with gross receipts above $298,000 the business enterprise tax on the wages, interest and dividends they pay. The state does not recognize S corporation status, so an S corporation files as a corporation. One return covers both taxes, due by the 15th day of the fourth month after the year ends. The line is shown from the $100,000 revenue band; a business below the threshold files nothing.

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.

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.
