What you need to know
Does the state make me have a registered agent?
Every LLC must name a registered agent with an in-state street address.
Statute: 5 M.R.S. § 105. go check legislature.maine.gov, last confirmed October 2026
Who can be the agent?
A commercial registered agent listed with the Secretary of State, or a noncommercial agent: an individual or entity serving as agent in Maine, or the holder of a named position in the company.
A qualifying owner can serve for free.
What does an agent cost?
You're looking at $99 to $149 a year for the services we'd use, $297 to $447 across three years.
Naming a different agent won't change any state fee.
What does an agent actually do?
Court papers and state notices for your company get delivered to its Maine address.
Ask how fast the agent tells you when something shows up, so you don't blow a deadline. Service of process, decoded
What else does the state bill every year?
The annual report is the one you can't forget. It's annual and runs $85. Per the state, it's due June 1.
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 be my own agent?
Yes, as long as you meet the state's rules on who can serve and on the address, both shown above.
What address does an agent need?
A noncommercial agent lists a physical street address in Maine, not a P.O. box. Commercial agents keep their address on file with the state.
What do the picks cost over three years?
Mainstay Filing comes out at $447; Maine Registered Agent.co comes out at $297; ME Registered Agent.org comes out at $297
Are the fees official?
Official Maine sources back the state side, and posted prices back the service side.
Do I have to use a service?
No. You can file with the state yourself. A service saves you time and can be your agent, but nothing makes you hire one.
Who should I use for a registered agent in Maine?
Go with Mainstay Filing first, then look at Maine Registered Agent.co and ME Registered Agent.org.
