What to know before you file
Does this state require a resident agent?
Every LLC must name a registered agent with an in-state street address.
Read the rule: M.G.L. c. 156C, § 5. sec.state.ma.us, last confirmed October 2026 for this guide
Who qualifies as an agent?
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.
When you fit the rule, you can fill the role for free.
What should I budget for an agent?
The recommended services charge $99 to $149 annually; three years cost $297 to $447.
The state bills the same amount with any agent.
What is the agent's job?
It acts as the LLC's contact in Massachusetts for court papers and state letters.
Ask how fast the agent tells you when something arrives, so nothing slips past a deadline. Service of process in one line
What does the LLC owe the state every year?
Keep the Limited Liability Company Annual Report current: you file it every year for $500. The due date, per the state, is on or before the anniversary date of filing of the certificate of organization; do not miss it.
To check the three-year number, add the formation filing, the next two reports and any minimum tax; costs with no fixed price are not counted.
FAQ
Is being my own agent allowed?
Yes, when you qualify under the state rule; many owners still pay for a service to keep their address private.
What type of address qualifies?
The address has to be a street address in Massachusetts. A post office address is not sufficient.
How do the three-year costs compare?
Totals to compare: MA Registered Agent.org at $297, Mainstay Filing at $447, Massachusetts Registered Agent.co at $297
Where do you get the fees?
Official Massachusetts documents supply the state fees, and the companies' own pricing pages supply the service fees. Both carry dates on this page.
Do I need to hire a service?
No. A service charges for labor and the agent role, not for anything the state demands.
Who ranks first in Massachusetts?
MA Registered Agent.org, because its service costs $99 annually and puts a street address on file. Then Mainstay Filing and Massachusetts Registered Agent.co.
