1. Maine Registered Agent.co: best for a Maine LLC that plans to stay local

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

9.6Editorial score
out of 10

Maine Registered Agent.co wins here: a $199 formation fee on top of the state's own, then $99 a year for the agent.

The plan gives the company an in-state street address as its registered office, and papers served on the company are scanned to your online account.

The annual report filing is not in its published prices, so you file it with Maine yourself every year.

Over three years it comes in under Mainstay Filing, and cost is one of our two heaviest criteria.

What you get

  • The formation filing
  • A first year of registered agent service

What we like

  • Year-one registered agent service included
  • $199, with the state filing fee on top
  • Agent at $99 yearly from year two

Cons

  • Does not take over the annual report
  • The EIN application is billed separately ($99)

2. Mainstay Filing: best for formation, agent and annual report for one price

$199 each year plus the state fee ($424 due at checkout)

9.1Editorial score
out of 10

Second place goes to Mainstay Filing: the Maine formation, your registered agent and the annual report all sit in a single $199 yearly charge.

Mainstay files the annual report for you as part of the renewal. Maine charges $85 every year, due June 1, and a late filing adds $50; the state's fee is passed through at cost.

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

What you get

  • Formation paperwork prepared and filed
  • A full year of registered agent service
  • The annual report, prepared and filed
  • The EIN application

What we like

  • One $199 yearly price that includes the annual report
  • The EIN application comes with it
  • Maine's fee is passed through at cost
  • $199 at renewal, nothing extra

Cons

  • From year two its agent costs $100 a year more than Maine Registered Agent.co's

Prices were read from each company's own pages on November 12, 2026. Maine's $175 filing fee goes on top of every row and is not counted in these totals.

How the order was set

Two criteria lead Filing Verdict's method at 35% apiece: total over three years and paperwork the price handles. Renewal behavior, match to the state and up-front pricing share the other 30%, and Maine came down to total over three years.

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