Legal Question in Business Law in Maryland

Re: S Corporation

You will want to check the statute in Maryland to see if the organization is "doing business" there (which, it is likely, it is). Each State provides guidance on this. If the company is "doing business" in Maryland then you will want to follow the procedure to register the Florida organization to be "doing business" in the State of Maryland.

Re: S Corporation

You should first check your corporate charter to make sure that the corporate mission as stated is broad enough to encompass the operation of a retail business. Even if it is, you may want to form a new MD corporation, so as to avoid cross-business liability (i.e., debts from one business affecting the other).
