Why Mainstay Filing is first
What split first and second in Maine: what one price covers, weighted at 30% in our method.
Maine expects a report every year with a $85 state fee and charges $50 when it is late. A price that includes filing it scores well on coverage, and that outweighed the lower three-year cost of ME Registered Agent.org.
Our method page lists all five criteria.
Maine LLC filing fee, from the state
$175 goes to the state for the Certificate of Formation (Form MLLC-6) under 31 M.R.S. sec. 1531 (certificate of formation); filing fee set by 31 M.R.S. sec. 1680, whichever service files it.
Processing: 10 to 15 business days (home page).
Yearly upkeep and your agent
Annual report: every year, $85, due June 1. Late fee $50. Every LLC must name a registered agent with an in-state street address.
