Why Mainstay Filing is placed first
Two criteria carry 31% each in this ranking, charge over three years and work taken off the founder. Renewal conduct, fit with local rules and pricing in plain sight share 38%, and in Maine the decisive one was work taken off the founder.
Mainstay's plan reaches further: papers served on the company are scanned within the same business day at no cost, the price is identical across all fifty states, and three government letters a year are scanned free. Maine Registered Agent.co charges less, so the margin is narrow.
Each criterion and its weight appear on How we rank.
What Maine requires of a registered agent (source: Maine Secretary of State)
Every LLC must name a registered agent with an in-state street address. A noncommercial agent lists a physical street address in Maine, not a P.O. box. Commercial agents keep their address on file with the state. Authority: 5 M.R.S. § 105.
The Maine annual report: its fee and due date
In Maine, the annual report comes due every year. $85 is payable to the state, and the deadline is June 1. Filing late adds $50. Notices about it are sent to your registered agent.
