Jay explains

Connecticut LLCs file their annual report between January 1 and March 31 each year, a change made in 2020 from the old anniversary month rule. The fee is $80. A general partnership that never registered with the state files no annual report in most states.

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

Connecticut keys its report to this date. Add it and the calendar places it.
