Prices were read from each company's own pages on November 12, 2026. Maryland's fees do not depend on which agent you choose.

The reasoning behind the order

Two criteria lead Filing Verdict's method at 35% apiece: total over three years and paperwork the price handles. Renewal behavior, match to the state and up-front pricing share the other 30%, and Maryland came down to total over three years.

MD Registered Agent.org totals $297 over three years, $150 under Mainstay Filing. A company that needs an agent in Maryland only gains little from fifty-state coverage, so the lower yearly price decided it.
