Registering a foreign LLC in Massachusetts: fee, form and who gets it

To register, the company files the Foreign Limited Liability Company Application for Registration (General Laws Chapter 156C, Section 48) with the Massachusetts Secretary of the Commonwealth, Corporations Division and pays the state's $500. Massachusetts also wants certificate of legal existence or good standing, issued within 90 days of the filing.

From then on the company owes the Foreign LLC annual report ($500), due anniversary of registration.

What to pull together first

  • Certificate of legal existence or good standing, issued in the 90 days before you file.
  • The company name exactly as the home state spells it, and when it was formed.
  • An in-state resident agent; any service the desk picked can fill that seat.
  • $500 for the state, paid when you file.
  • A date on your calendar for the Foreign LLC annual report and its $500 fee.

What it costs to ignore Massachusetts registration

Until it registers, an outside LLC has no right to sue in Massachusetts courts (G.L. c. 156C, 54(a)). The contracts it signs stay good (G.L. c. 156C, 54(a)).
