Our top pick

1. Maine Registered Agent.co: best for a Maine LLC with no plans to expand

Form for $199; the agent is $99 a year after that, plus the state fee

Editorial score 9.6 out of 10

The desk picks Maine Registered Agent.co: $199 to form, state fee extra, then $99 a year for the agent.

You get an in-state street address as the registered office, and papers served there are scanned into your account.

It leaves the annual report out of its prices, so you send that filing to Maine yourself every year.

Add up three years and it undercuts Mainstay Filing, and cost is one of our two heaviest criteria.

Formation, agent and report

3. Mainstay Filing: best for formation, agent and annual report in a single price

$199 a year plus the state fee, $424 due at checkout

Editorial score 9.0 out of 10

Third, Mainstay Filing: the formation, the registered agent and the annual report all ride on one $199 yearly price, renewing at $199.

Mainstay files the annual report for you when you renew. Maine wants $85 every year, by June 1, and a late filing tacks on $50; Mainstay hands the state's fee through at cost.

Maine Registered Agent.co undercuts Mainstay Filing by $200 over three years, and that is why Mainstay sits lower on cost.

In the price

  • Your LLC formation, handled
  • Registered agent service for the full year
  • Annual report, filed by Mainstay
  • EIN application handled

Strengths

  • Maine's fee passes through at cost
  • One $199 yearly price that takes in the annual report
  • EIN application comes with the package
  • $199 on renewal, nothing extra

Service Year one Year two Year three Bill over three years Annual report filed on your behalf
Maine Registered Agent.co $199 $99 $99 $397 No

How the desk made the call

The Formation Desk counts spend over three years and work the price removes for 33% each; what renewal looks like, fit with the state and plain price display make up the other 34%. What tipped Maine: spend over three years.

Maine Registered Agent.co comes to $397 over three years, $200 less than Mainstay Filing. Mainstay would file the annual report too, but an owner can do that alone for just the state fee, so the lower price won.

The full criteria and weights are on How we rank.
