Three years in, what has each cost?

Totals to compare: Registered Agent MS.org at $397, Mainstay Filing at $497, Mississippi Registered Agent.co at $397, and state fees are separate.

What sources do you use?

State-set fees come from Mississippi's publications; what services charge comes from the prices they post.

Do I need to hire a service?

If you meet the rules on this page, you can file on your own, and the state charges the same either way.

Will a service file the registration for me?

Yes, filing is part of what these companies sell, and the state fee does not move.

Who is your first choice in Mississippi?

Registered Agent MS.org comes first: $199 over the state fee at the start, then $99 yearly. Next, Mainstay Filing and Mississippi Registered Agent.co.
