Before transacting interstate or foreign business in Maryland, a foreign limited liability company (“LLC”) shall register to transact business with the State Department of Assessments and Taxation (“SDAT”) in accordance with Md. Corp. & Ass’ns. Code Ann. § 4A-1002:

“(a) Requirement. — Before doing any interstate, intrastate, or foreign business in this State, a foreign limited liability company shall register with the Department.”

           Under § 4A-1002, a foreign LLC is required to complete an application setting forth, among other information, its name, state of organization, business purpose, and resident agent, and pay a filing fee to SDAT.

          Md. Corp. & Ass’ns. Code Ann. § 4A-1007 states that any foreign limited liability company that fails to register with the SDAT in accordance with § 4A-1002 is barred from maintaining a lawsuit in any court of this State, as follows:

“(a) Barred from maintaining suit. — If a foreign limited liability company is doing or has done any intrastate, interstate, or foreign business in this State without complying with the requirements of this subtitle, the foreign limited liability company and any person claiming under it may not maintain suit in any court of this State, unless the limited liability company shows to the satisfaction of the court that:

   (1) The foreign limited liability company or the person claiming under it has paid the penalty specified in subsection (d)(1) of this section; and

   (2) (i) The foreign limited liability company or a successor to it has complied with the requirements of this title; or

     (ii) The foreign limited liability company and any foreign limited liability company successor to it are no longer doing intrastate, interstate, or foreign business in this State.”  

In essence, Md. Corp. & Ass’ns. Code Ann. § 4A-1007 bars a foreign LLC from acting as a plaintiff in any Maryland state or federal court if the LLC is doing or has done “any intrastate, interstate, or foreign business” in Maryland without registering or qualifying with SDAT. 

Foreign corporations face nearly identical Maryland statutes.  See Md. Corp. & Ass’ns. Code Ann. §§ 7-202,  and 7-301, respectively. 

The Maryland Court of Appeals stated the following in Yangming Marine Transport Corporation v. Revon Products U.S.A., Inc., 311 Md. 496 (1988):

“As pointed out above, under § 7-301, a foreign corporation that has not complied with § 7-202 or § 7-203 is barred from suing in Maryland if the corporation “is doing . . . any intrastate, interstate, or foreign business in this State.”  …. Instead, we have held that § 7-301 embodies a test for determining whether a foreign corporation is “doing business” in Maryland. See G.E.M., Inc. v. Plough, Inc., 228 Md. 484, 486, 180 A.2d 478, 480 (1962). Under this test, § 7-301 bars an unqualified or unregistered foreign corporation from suing in Maryland courts only if the corporation is doing such a substantial amount of localized business in this State that the corporation could be deemed “present” here. See, e.g., S.A.S. Personnel Consult. v. Pat-Pan, 286 Md. 335, 339-340, 407 A.2d 1139, 1142 (1979); G.E.M., Inc. v. Plough Inc., supra, 228 Md. at 488-489, 180 A.2d at 480-481.
