The questions that matter
Does the state make me have a resident agent?
Every LLC must name a registered agent with an in-state street address.
Statute: M.G.L. c. 156C, § 5. go check sec.state.ma.us, last confirmed October 2026
Who can be the 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.
A qualifying owner can serve for free.
What does an agent cost?
Agent prices on this page start at $99 to $149 a year, and three years of service come to $297 to $447.
The state's fees stay the same whoever you name.
Why does the state want one?
It's the LLC's contact in Massachusetts for legal papers and state letters.
Ask how fast the agent tells you when something shows up, so you don't blow a deadline. What's service of process?
What else does the state bill every year?
Set aside $500 each year for the Limited Liability Company Annual Report. Put the state's date on your calendar: on or before the anniversary date of filing of the certificate of organization.
On jobs the price actually covers (30% of the score), Mainstay Filing wins.
We run five tests: money out the door in three years (35%), jobs the price actually covers (30%), no hunting for the price (14%), no surprise at renewal (11%) and where it works (10%).
Only the first pick works in all fifty states, and that matters the day you register somewhere else.
The last row is our math, not the state's: filing fee, plus the reports in years two and three, plus any minimum tax. If a cost has no fixed amount, like a newspaper notice, it's explained above and left out.
More questions
Can I name myself?
Usually. If you fit the state's rule on who qualifies and which address counts, go ahead.
What address does an agent need?
The address has to be a street address in Massachusetts. A post office address is not sufficient.
What's the three-year damage for each?
Over three years you're looking at $447 at Mainstay Filing, $297 at MA Registered Agent.org, $297 at Massachusetts Registered Agent.co
Are the fees official?
Official Massachusetts sources back the state side, and posted prices back the service side.
Is a service required?
No law says you need a service. It's a convenience you pay for.
Who should I use for a registered agent in Massachusetts?
Mainstay Filing is first: the price doesn't change by state, $149 a year, and renewal is $149. Then comes MA Registered Agent.org and Massachusetts Registered Agent.co.
