Our favorite is Maryland Registered Agent.co, because forming in Maryland is $199 plus the state fee, and your first year as resident agent is included, then $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 Business Entity Annual Report isn't part of its published price, so you send it to Maryland yourself every year.
Over three years it costs less than Mainstay Filing, and cost is one of our two biggest criteria.

Coming in second is Mainstay Filing, because $199 a year covers the Maryland formation, a year as your resident agent and the annual report, and it renews at $199.

We took each price from the company's own pages on November 12, 2026. On top of every row, Maryland charges a $100 filing fee, which isn't in these totals.
How we scored these
Here's how we scored it: three-year cost and filings in the price are worth 29% each, and renewal price, state fit and up-front totals split the other 42%. In Maryland, three-year cost made the difference.
Maryland Registered Agent.co comes to $397 over three years, which is $200 less than Mainstay Filing. Mainstay would file the Business Entity Annual Report too, but you can do it yourself for the state fee, so the lower price won here.
