Researched and written by the Launchwise Review editorial team
For a 2026 launch in Massachusetts, Launchwise Review grades foreign registration services this way: Mainstay Filing ($199), MA Registered Agent.org ($199) and Massachusetts Registered Agent.co ($199). Mainstay Filing earns the top grade here: $199 on top of the state fee, a free first year as resident agent and the same price in any state.

Number one here

1. Mainstay Filing: best for founders working in several states

$199 for the service and the state fee besides; agent service is $149 a year from the second year

Our mark 9.2 out of 10

Top grade, Mainstay Filing: the Massachusetts registration costs $199, the first resident agent year is free, and later years are $149.

Once the free first year ends, the agent is $149 a year, in any state.

It runs $100 above MA Registered Agent.org across three years; the extra paperwork it handles is worth that to us.

  • No-cost scanning of served papers within the same business day

Pros

  • $199 for the service, with the state fee added
  • One price in every state

What drove the grades

At Launchwise Review, cost to launch and stay and launch paperwork handled each count for 26% of a grade, and renewal behavior, state match and price transparency split the remaining 48%. In Massachusetts, launch paperwork handled made the call.

Adding a second state means dealing with two states, and one provider at one price in both earned the stronger coverage grade, ahead of MA Registered Agent.org.

Every criterion and weight is listed on How we rank.

Opening in Massachusetts as a foreign LLC: fee, form and office

Your registration goes to the Massachusetts Secretary of the Commonwealth, Corporations Division, on the Foreign Limited Liability Company Application for Registration (General Laws Chapter 156C, Section 48). Budget $500 for the state. Have certificate of legal existence or good standing in hand too, dated within 90 days of filing; Massachusetts asks for it.

Calendar item for later: the Foreign LLC annual report at $500, due anniversary of registration.

Before you file, get these together

  • Certificate of legal existence or good standing, issued within 90 days of your filing date.
  • Your company's exact legal name and the date it was formed at home.
  • A resident agent with a street address in the state; every company graded on this page can serve.
  • The $500 state fee, ready to pay with the filing.
  • A calendar reminder for the Foreign LLC annual report and its $500 fee.

What skipping Massachusetts registration can cost you

Without registration, an outside LLC cannot bring a lawsuit in Massachusetts courts (G.L. c. 156C, 54(a)). Contracts it signs remain valid (G.L. c. 156C, 54(a)).
