Maryland foreign LLC registration fee and rules, as written by the state
An LLC from another state has to register in Maryland before doing business here. You file the Limited Liability Company Registration (For non-Maryland Limited Liability Company) with the Maryland State Department of Assessments and Taxation (SDAT), Charter Division and pay $100. Also attach written proof of existence from the home state, equivalent to a certificate of good standing obtained in the last 60 days.
What staying unregistered can cost: a ban on suing in Maryland courts until it registers (4A-1007(a)).
No service means three years of state fees at $700. Hiring one adds $397 to $497 in the same period.
