What owners want to know

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, read in October 2026 for this answer

Who qualifies as 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.

A qualifying owner can serve at no cost.

What will I pay an agent each year?

Our picks charge $99 to $149 annually, and three years total $297 to $447.

Whichever agent you pick, the state's fees stay the same.

Why does the state want an agent?

The agent signs for lawsuits and state mail addressed to the LLC, using a street address in Maine.

A good agent tells you quickly when something arrives, which is worth asking about before you sign up. Service of process, explained

What does the LLC owe the state each year?

The annual report repeats every year, at $85 each time. Due date, as the state puts it: June 1.

The last row is arithmetic, not a state figure: filing fee, plus the reports due in years two and three, plus a minimum tax where one applies. Open-ended costs stay out.

Still wondering?

Can I be my own agent?

Yes, provided you meet the state's rules on who may serve and on the address, both laid out 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?

For three years you would pay $447 at Mainstay Filing, $297 at ME Registered Agent.org, $297 at Maine Registered Agent.co

Where do these numbers come from?

State fees come from Maine's official documents, and service fees come from each company's own pricing page. Both carry dates on this page.

Do I have to use a service?

Hiring help is a convenience you pay for, never a legal duty.

Which one do you recommend in Maine?

Ask Mainstay Filing first, then compare ME Registered Agent.org and Maine Registered Agent.co.
