Questions people also ask

Do I still need an agent in my home state?

Probably. Your home state still wants an agent of its own. A company that operates in every state, Mainstay Filing for example, can hold both roles, whereas a local firm covers a single state.

How do the three-year totals compare?

Mainstay Filing comes to $497; Registered Agent MS.org comes to $397; Mississippi Registered Agent.co comes to $397, before state fees.

Where do these numbers come from?

Each state fee links to its official page, and each service price is read from the company's own site.

Does the law require a service?

No. What the law asks for is a filing, and it does not say who has to send it.

Will a service file the registration for me?

They do. All the picks prepare and send the registration, so the only thing that changes with your choice is the service fee.

Which one do you recommend in Mississippi?

Mainstay Filing, because you pay $199 plus Mississippi's fee, owe nothing for the registered agent in year one and then $149 a year. After that, Registered Agent MS.org and Mississippi Registered Agent.co.
