Why row one is row one

For Maine, the term that decided it was items covered per dollar (28% of the score), where Mainstay Filing came out ahead.

Filing the annual report for you outweighed ME Registered Agent.org's smaller three-year total.

If you need the EIN application, the rows cross in year 2, as Mainstay Filing passes ME Registered Agent.org.

The LLC exists once the Maine Secretary of State accepts the Certificate of Formation (Form MLLC-6) along with $175. Every LLC must name a registered agent with an in-state street address.

Official wording: legislature.maine.gov (checked October 2026) as the source

Without a service
