The steps

  1. Step
    1

    Confirm that you must register

    Out-of-state LLCs that transact business in Maryland file a foreign registration. If the LLC works there without registering: Maryland courts are closed to an unregistered LLC as a plaintiff (4A-1007(a)). Its contracts remain valid (4A-1007(b)).

    Where this comes from: Class notes: mgaleg.maryland.gov (October 2026)

  2. Step
    2

    Request proof of good standing from home

    Maryland asks for written proof of existence from the home state, equivalent to a certificate of good standing, no older than 60 days.

    Do this step right before you file.

  3. Step
    3

    Choose the Maryland resident agent

    Every LLC must name a registered agent with an in-state street address. The address has to be a Maryland address on file with the State Department of Assessments and Taxation; P.O. boxes are not accepted. The LLC also keeps a principal office in Maryland.

    Our graded picks all serve as the resident agent.
