How registration works in Massachusetts

  1. Task 1

    Find out whether you have to register

    Out-of-state LLCs that do business in Massachusetts register first as foreign LLCs. Skipping registration has a price: An LLC that has not registered cannot be a plaintiff in Massachusetts (G.L. c. 156C, 54(a)). The agreements are not voided (G.L. c. 156C, 54(a)).

  2. Task 2

    Ask your home state for proof of good standing

    Get certificate of legal existence or good standing, from the last 90 days.

    Save this task for just before you file.

  3. Task 3

    Get a resident agent with a Massachusetts address

    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.

    Any of the recommended services can fill this seat.

  4. Task 4

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

    Fill in the Foreign Limited Liability Company Application for Registration (General Laws Chapter 156C, Section 48), include $500, and mail or upload it to the Massachusetts Secretary of the Commonwealth, Corporations Division.
