Maine registered agent pricing in 2026: first year, renewals, three-year total
Every price comes from the company's own pages as of November 12, 2026. Maine's own fees stay the same whichever agent you pick.
Why Mainstay Filing is first
Filing Shortlist puts 28% of the weight on three-year price and 28% on what the price covers. The remaining 44% goes to renewal terms, fit for the state and price clarity, and for Maine the deciding factor was what the price covers.
Mainstay's plan covers a wider area: it scans papers served on the company the same business day at no charge, the price stays the same in all fifty states, and three government letters a year are scanned free. Maine Registered Agent.co is cheaper, and the two end up close.
Every criterion and weight is set out on How we rank.

The Maine annual report: price and deadline
Every company formed here files the annual report every year. The state charges $85 and wants it June 1. Being late adds $50. The reminders about it go to your registered agent.
