Registered Agent

In Maine, one of the requirements for a corporation or LLC is that a Registered Agent has to be named.  This person is a single point of contact in case the business needs to be served with legal papers or contacted by the state. One of the business owners often file as the entities Registered Agent. When they file, their home address is often used (PO Boxes aren’t allowed) and the owner's name and address is now a public record that can be looked up by anyone. This can be a big concern, especially for home-based businesses. Using a commercial Registered Agent service will keep their personal address from being public record..

Business Licenses

The business name registration is different from business licensing in Maine.  The Maine Department of Economic and Community Development has more information regarding Maine business licenses.
