By the Biz Formation Report editorial team

Biz Formation Report ranks LLC services in Maine for 2026 as Mainstay Filing ($199), ME Registered Agent.org ($199) and Maine Registered Agent.co ($199), in that order. Mainstay Filing earns the top grade: $199 a year buys the Maine formation, a year as your registered agent and the annual report filing, then renews at $199.

1. Mainstay Filing: best for formation, agent and annual report on one invoice

Score9.2out of 10
$199 a year plus the state fee, $424 due at checkout

Top grade, Mainstay Filing: the formation filing, the registered agent and the annual report come to $199 a year, renewing at $199.

The renewal covers the annual report, which Mainstay files for you. Maine collects $85 every year, with a deadline of June 1, and a late filing adds $50; Mainstay passes the state's fee through at cost.

Over three years Mainstay costs $200 more than ME Registered Agent.org; our grading treats the broader coverage as worth that.

All prices were taken from the companies' own websites on November 12, 2026. Maine's $175 filing fee is payable on top of each row and is not part of these totals.

The basis for the order

Of the grade, 32% rests on three-year bill and 32% on what the money buys; renewal handling, local rules match and pricing openness share the remaining 36%. What the money buys decided Maine.

Maine requires a report every year, charging $85, plus $50 if it is late. Mainstay's price includes the filing and ME Registered Agent.org's does not, which outweighed ME Registered Agent.org's lower three-year cost in the coverage grade.
