How the desk made the call

The Formation Desk counts spend over three years and work the price removes for 33% each; what renewal looks like, fit with the state and plain price display make up the other 34%. What tipped Mississippi: spend over three years.

Registered Agent MS.org comes to $397 over three years, $100 less than Mainstay Filing. Both include a first year of agent service, so the renewal price made the call.

Registering a foreign LLC in Mississippi: fee, form and who gets it

To register, the company files the Application for Registration of Foreign Limited Liability Company (Filing F0200) with the Mississippi Secretary of State, Business Services and pays the state's $250. Mississippi also wants certificate of good standing or existence, issued within 180 days of the filing.

From then on the company owes the Foreign LLC annual report ($250), due April 15.

What to pull together first

  • Certificate of good standing or existence, issued in the 180 days before you file.
  • The company name exactly as the home state spells it, and when it was formed.
  • An in-state registered agent; any service the desk picked can fill that seat.
  • $250 for the state, paid when you file.
  • A date on your calendar for the Foreign LLC annual report and its $250 fee.

What it costs to ignore Mississippi registration

Until it registers, an outside LLC has no right to sue in Mississippi courts (Miss. Code Ann. 79-29-1013(1)). The contracts it signs stay good (Miss. Code Ann. 79-29-1013(2)). A daily penalty of $10 can run on top.
