Massachusetts Registered Agent.co Review (2026)

Massachusetts Registered Agent.co is a Massachusetts resident agent service at $99 a year, the same $99 at renewal. You get a registered office address inside the state, and a scan of each legal paper served on the company lands in your online account. Starting a Massachusetts LLC with this company runs $199 above the state fee, and the first year as your agent is thrown in. Registering an outside company in Massachusetts through it runs $199 on top of the state fee. Bottom line: it suits a Massachusetts-only company that likes a fixed agent price and will handle its own Limited Liability Company Annual Report.
