More questions
Do I still need an agent at home?
Yes. Your home state has its own agent rule, and Mainstay Filing can cover both states from one account.
What's the three-year damage for each?
MD Registered Agent.org comes out at $397; Mainstay Filing comes out at $497; Maryland Registered Agent.co comes out at $397, with state fees on top.
Where do these numbers come from?
Official Maryland sources back the state side, and posted prices back the service side.
Is a service required?
No. You can file with the state yourself. A service saves you time and can be your agent, but nothing makes you hire one.
Will a service file it for me?
All of them do, so the service fee's the only difference.
Who should I use for a foreign registration service in Maryland?
MD Registered Agent.org, because the service fee's $199, with the first year of agent service included, and renewal is $99. After that, Mainstay Filing and Maryland Registered Agent.co.
