Layer by layer

Is a registered agent required?

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

The law underneath: 5 M.R.S. § 105. legislature.maine.gov holds the original, confirmed October 2026

Who is allowed to 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 be the agent for free.

What is inside an agent's price?

A year of agent service runs $99 to $149 with our picks, and three years run $297 to $447.

No state fee depends on the agent you name.

What does an agent handle for the LLC?

Whatever legal paper is meant for the LLC in Maine goes to the agent, who passes it along.

What matters is that nothing important sits unnoticed while you are away. Service of process, unpacked

Is anything else due every year?

Underneath it all, one filing repeats: the annual report, every year, at $85 each time. The state phrases its deadline like this: June 1.

maine.gov holds the original, confirmed August 2026

Why is the stack in this order?

Mainstay Filing is strongest on what is inside the price, a layer worth 29% of the score.

Two layers carry most of the weight, total across three years (34%) and what is inside the price (29%).

Reach decided it: fifty states against one.

More boxes to open

May an owner serve as agent?

Usually. Check who qualifies and which address counts, and if you fit, you can.

Which addresses does the state accept?

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 stacks up to $447, ME Registered Agent.org stacks up to $297, Maine Registered Agent.co stacks up to $297

What do these numbers rest on?

Official Maine paperwork stands behind every state fee here, and every service price traces back to the company's own pricing.

Does the law require one?

No law requires a service. It is a paid convenience.
