Maine: the ranking

Wondering about the order? How we pick explains it.
Best overall

1. Mainstay Filing: best for owners who want the upkeep handled

$199 a year plus $175 for the state

Mainstay Filing gets the top spot: for $199 a year it forms your LLC, acts as your registered agent and files the annual report, and it renews at $199.

It isn't the smallest bill. ME Registered Agent.org is $200 less over three years, and the gap pays for more of the paperwork.

It handles each annual report and adds just the $85 the state charges.

Your money buys

  • The state filing, taken care of
  • Registered agent the whole year
  • Annual report filed for you
  • Help getting your EIN
  • No markup on the state fee

The good

  • Stays at $199 when you renew
  • $199 each year buys everything on this list
  • You won't pay extra to get an EIN

Trade-offs

  • $100 a year more than ME Registered Agent.org once you renew
A Maine favorite

2. ME Registered Agent.org: best for keeping three-year cost down

Formation is $199 plus the state fee, and the agent renews at $99

Why ME Registered Agent.org second? Honestly, three years add up to $397 with its $99 renewal.

You'd handle the annual report separately.

Your money buys

  • The state filing, done
  • Agent included for year one

The good

  • $99 a year from year two
  • Year one of the agent comes with it
  • Just $199 to get formed

Trade-offs

  • You'd still be handling the annual report
  • They charge $99 to apply for your EIN
A Maine favorite

3. Maine Registered Agent.co: best for a low agent renewal

Formation is $199 plus the state fee, and the agent renews at $99

Why Maine Registered Agent.co third? Honestly, three years add up to $397 with its $99 renewal.

You'd handle the annual report separately.

It charges what ME Registered Agent.org charges, so the order between them is close.
