Maryland registered agent prices, 2026: year one, renewal and three-year outlay

ProviderYear 1Year 2Year 3Three-year outlayRenewal at the same price
MD Registered Agent.org$99$99$99$297Yes
Mainstay Filing$149$149$149$447Yes
Maryland Registered Agent.co$99$99$99$297Yes

All prices were taken from the companies' own websites on November 12, 2026. Maryland's own fees are the same whichever agent is named.

The basis for the order

Of the grade, 32% rests on three-year bill and 32% on what the money buys; renewal handling, local rules match and pricing openness share the remaining 36%. Three-year bill decided Maryland.

Total outlay with MD Registered Agent.org over three years: $297, $150 less than Mainstay Filing. An agent needed only in Maryland gains little from fifty-state coverage, so the lower yearly price decided the grade.

Every criterion and weight is listed on How we rank.
