Our top pick in Maine

$199 a year, and the state fee goes on top ($424 at checkout)

Our favorite is Mainstay Filing, because $199 a year covers the Maine formation, a year as your registered agent and the annual report, and it renews at $199.
When your plan renews, Mainstay files the annual report for you. Maine charges $85 every year for it, and the date is June 1, and a late one costs $50 more. Mainstay passes the state's fee along at cost.
Over three years it costs $200 more than ME Registered Agent.org, and for us the extra things it handles are worth that.

Our score
8.9out of 10
8.9 out of 10
Coming in second is ME Registered Agent.org, because the Maine formation costs $199 over the state's fee, with the registered agent free the first year, and keeping the agent is $99 a year.
You get a street address in the state for your registered office, and any papers served on the company are scanned into your online account.
The annual report isn't part of its published price, so you send it to Maine yourself every year.
3. Maine Registered Agent.co: best for a Maine-only LLC
$199 to form, then $99 a year for the agent, with the state fee on top
Our score

In third place is Maine Registered Agent.co, because the Maine formation costs $199 over the state's fee, with the registered agent free the first year, and keeping the agent is $99 a year.
You get a street address in the state for your registered office, and any papers served on the company are scanned into your online account.
The annual report isn't part of its published price, so you send it to Maine yourself every year.
Price and features don't set ME Registered Agent.org apart from Maine Registered Agent.co; pick the one you like.

We took each price from the company's own pages on November 12, 2026. On top of every row, Maine charges a $175 filing fee, which isn't in these totals.
How the order came together
LLC Review Desk gives three-year cost 29% and filings in the price 29%, then divides 42% among renewal price, state fit and up-front totals. For Maine, it came down to filings in the price.
In Maine you'll need a report each year ($85 to the state), and sending it late adds $50. Mainstay's price includes that filing and ME Registered Agent.org's doesn't, which is why coverage beat ME Registered Agent.org's lower three-year cost.
You can read every criterion and weight on How we rank.
