The primer, move by move

  1. Move 1

    Does the rule reach your LLC?

    Operating here through an LLC formed elsewhere means foreign registration. Skip registration and: A claim from an unregistered LLC will not go forward there (G.L. c. 156C, 54(a)). Its contracts remain enforceable (G.L. c. 156C, 54(a)).

    Where this comes from: Source page sec.state.ma.us, October 2026

  2. Move 2

    Pull the document from your home state

    Massachusetts requires certificate of legal existence or good standing, dated within 90 days.

    Order it when everything else is ready.

  3. Move 3

    Choose the Massachusetts resident agent

    Every LLC must name a registered agent with an in-state street address. The address has to be a street address in Massachusetts. A post office address is not sufficient.

    Our picks cover this.

    Where this comes from: Source page sec.state.ma.us, October 2026

  4. Move 4

    Submit the Foreign Limited Liability Company Application for Registration (General Laws Chapter 156C, Section 48)

    Prepare the Foreign Limited Liability Company Application for Registration (General Laws Chapter 156C, Section 48), add $500, and deliver both to the Massachusetts Secretary of the Commonwealth, Corporations Division.

    Where this comes from: Source page sec.state.ma.us, October 2026

  5. Move 5

    Handle Massachusetts's repeating filing

    Next up: the Foreign LLC annual report, $500, anniversary of registration.

The cost of this primer

State fees, years one to three The state $1,500
