How the order was decided
Our method scores three-year cost (30%) and what one price covers (30%) most heavily, then renewal terms, fit for the state and price clarity. Here the order came down to what one price covers.
On coverage, Mainstay's agent plan does more: one price in every state and free same-day scanning of served papers. ME Registered Agent.org is cheaper and scores close behind.
Our method page lists all five criteria.
Maine registered agent requirements from 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. The rule is in 5 M.R.S. § 105.
Maine's annual report and your agent
$85 every year, due June 1: that is the annual report. The late fee is $50. The state writes to your registered agent about it.
