Questions and answers

Do I have to name a registered agent?

Every LLC must name a registered agent with an in-state street address.

The law behind it: 5 M.R.S. § 105. legislature.maine.gov · October 2026 · checked

What does the state require of an 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.

Qualify, and the job can be yours for free.

How much per year for an agent?

Budget $99 to $149 a year, or $297 to $447 for three.

Whoever you name, state fees stay the same.

What does the agent handle?

When a lawsuit or state letter reaches your LLC in Maine, the agent is who receives it.

What matters is that nothing important goes unnoticed while you're out. What does "service of process" mean?

Does the LLC owe the state anything every year?

Keep the annual report current. You file it every year for $85. The state lists the due date as June 1, so don't let it slide.

A few more

Can an owner serve as agent?

Yes, as long as you fit the rule. Many owners still hire a service for privacy.

Where does the agent have to be located?

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.

How do the three-year costs stack up?

Mainstay Filing $447; ME Registered Agent.org $297; Maine Registered Agent.co $297

Can I check these fees?

The state fees come from Maine's own documents, and the service prices come from the companies' sites. We put dates on both.

Does the state make me use a service?

You can skip it. The state's fee is the same whichever way you file.

Which registered agent would you hire in Maine?

Mainstay Filing comes first: its price doesn't change by state: $149 a year, $149 at renewal. Then come ME Registered Agent.org and Maine Registered Agent.co.
