The Massachusetts agent, in order

  1. Move 1

    What Massachusetts wants from an agent

    Every LLC must name a registered agent with an in-state street address.

    Where this comes from: Per sec.state.ma.us, as of October 2026

  2. Move 2

    Check eligibility

    A Massachusetts resident, a Massachusetts corporation, or a corporation from another state authorized to do business in Massachusetts. State regulations (950 CMR 112.13) also allow other business entities authorized in Massachusetts. Statute: M.G.L. c. 156C, § 5.

  3. Move 3

    Meet the address rule

    The address has to be a street address in Massachusetts. A post office address is not sufficient.

    A service provides a Massachusetts street address, so yours stays off the record.

  4. Move 4

    Serve yourself or hire one

    Our recommended agents charge $99 to $149 a year; serving yourself works for those who qualify.

  5. Move 5

    Get the agent on record

    New companies list the agent on the Limited Liability Company Certificate of Organization. Replacing the agent later means filing again with the Massachusetts Secretary of State.

    Where this comes from: Per sec.state.ma.us, as of October 2026

  6. Move 6

    Keep the details accurate

    Anything the state sends about the Limited Liability Company Annual Report goes to your resident agent. The filing costs $500 every year, due on or before the anniversary date of filing of the certificate of organization.

    Where this comes from: Per malegislature.gov, as of August 2026
