The Massachusetts registration, in order

  1. Step 1: Decide whether Massachusetts registration is needed

    Formed somewhere else but doing business in Massachusetts? Then the LLC registers there as a foreign LLC. Skipping it has consequences: No lawsuits as plaintiff before registering (G.L. c. 156C, 54(a)). Signed contracts keep their force (G.L. c. 156C, 54(a)).

    Official source: Per sec.state.ma.us, last confirmed October 2026

  2. Step 2: Get your home state's certificate

    Include certificate of legal existence or good standing, no older than 90 days.

    TipOrder it last so it is still recent when you file.

  3. Step 3: Appoint a resident agent in Massachusetts

    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.

    TipEach of our picks includes the resident agent.

    Official source: Per sec.state.ma.us, last confirmed October 2026

  4. Step 4: Send in the Foreign Limited Liability Company Application for Registration (General Laws Chapter 156C, Section 48)

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

    Official source: Per sec.state.ma.us, last confirmed October 2026

  5. Step 5: After you register

    Registered foreign LLCs file the Foreign LLC annual report ($500), anniversary of registration.
