Your questions, answered

Do I have to register an LLC from another state?

Doing business in Maryland with an LLC formed somewhere else means registering at the start.

If you skip registering, you could face its access to Maryland courts as a plaintiff is cut off (4A-1007(a)).

Yes. The state where you formed the LLC keeps its own agent rule, and Mainstay Filing can handle both states on one account.

What's the three-year total for each?

Three-year totals are MD Registered Agent.org, $397; Maryland Registered Agent.co, $397; Mainstay Filing, $497, and state fees are separate.

Can I check these fees?

Maryland's fee schedules and forms for state costs; each company's price page for service costs.

Do I need to hire a service?

No law says you must hire anyone.

Who actually submits the registration?

Yes, because filing is what these companies sell, and the state fee stays put.
