More questions
Can I be my own agent?
Yes, if your address and status match the rule. Lots of owners still pay a service to keep their address private.
What address does an agent need?
The address has to be a Maryland address on file with the State Department of Assessments and Taxation; P.O. boxes are not accepted. The LLC also keeps a principal office in Maryland.
What do the picks cost over three years?
Over three years you're looking at $297 at Maryland Registered Agent.co, $447 at Mainstay Filing, $297 at MD Registered Agent.org
Are the fees official?
Official Maryland sources back the state side, and posted prices back the service side.
Do I have to use a service?
No. You can file with the state yourself. A service saves you time and can be your agent, but nothing makes you hire one.
Who should I use for a registered agent in Maryland?
Maryland Registered Agent.co is first: $99 a year, then $99, is a fair deal for an LLC that stays in Maryland. Then comes Mainstay Filing and MD Registered Agent.org.
