Number one here

1. Maine Registered Agent.co: best for a Maine LLC that wants to stay close to home

$199 to form, then $99 a year for the agent, plus the state fee

Our mark 9.6 out of 10

Top grade, Maine Registered Agent.co: $199 for formation plus the state fee, then $99 yearly for the agent.

You get an in-state street address for the registered office, and any papers served on the company are scanned into your online account.

The annual report is not in its published price, so that task stays on your list with Maine, due every year.

On a three-year bill it comes in under Mainstay Filing, and that is a heavily weighted criterion for us.

In the price

  • Formation prepared and filed
  • A first year as your registered agent

Pros

  • $99 each year for the agent from year two
  • The first year as your registered agent is free
  • Forms the LLC for $199, state fee extra

3. Mainstay Filing: best for formation, agent and annual report wrapped into one price

Our mark 9.2 out of 10

Rounding out the list is Mainstay Filing: the Maine formation, your registered agent and the annual report are bundled at $199 a year.

When renewal comes, Mainstay prepares and files the annual report so it is off your list. The Maine fee is $85 every year, with a June 1 deadline, and being late adds $50; Mainstay passes the fee along at cost.

Maine Registered Agent.co is $200 lower across three years, which puts Mainstay Filing behind it on cost.

How we graded this list

At Launchwise Review, cost to launch and stay and launch paperwork handled each count for 26% of a grade, and renewal behavior, state match and price transparency split the remaining 48%. In Maine, cost to launch and stay made the call.

Maine Registered Agent.co comes to $397 over three years, $200 under Mainstay Filing. Mainstay would file the annual report too, but an owner can handle it alone for the state fee, so the lower price took this page.

Every criterion and weight is listed on How we rank.
