Step-by-step foreign qualification requirements, fees, and filing instructions for Illinois LLCs expanding into Maryland.
Before filing, verify that your LLC name (or a distinguishable variation) is available in Maryland. If your exact name is already taken, you may need to register under a fictitious or assumed name.
Search the business name register on the Maryland State Department of Assessments and Taxation website before you file.
Maryland requires a Certificate of Good Standing from Illinois to prove your LLC is in good standing. The fee is $25. Available to order online. No state-imposed expiration; third parties typically require certificate dated within 30-60 days.
Order from Illinois ↗Submit your application along with the Certificate of Good Standing and the $100 filing fee. Processing time is 7-10 business days. Expedited processing available for $50. Online filing is available.
Maryland filing portal ↗You must designate a registered agent with a physical address in Maryland to accept legal documents on behalf of your LLC. This is required as part of the foreign qualification application.

Maryland's Limited Liability Company Act, codified at Title 4A of the Corporations and Associations Article, lists activities at Section 4A-1009 ('Doing business'). NOTE: Maryland's safe harbors list is non-standard. It does not match the typical RMBCA enumeration (omits independent contractors, soliciting orders, interstate commerce, isolated transactions) and includes foreclosure-specific activities not found in other states. Subsection (b) carves IN ownership of income-producing property as transacting business. Maryland uses 'doing business' rather than 'transacting business.' The list applied here is the standard RULLCA list and may need state-specific tailoring.
A registered agent is required for foreign qualification. These services operate in all 50 states.
