Massachusetts resident agent requirements, as written by the state (Massachusetts Secretary of State)
Every LLC must name a registered agent with an in-state street address.
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. Rule in force: M.G.L. c. 156C, § 5.
The address has to be a street address in Massachusetts. A post office address is not sufficient.
