see sos.ms.gov, October 2026
How much should I budget to register?

The state's three-year fees come to $750. see sos.ms.gov, October 2026
Where is the paperwork sent?
You file the Application for Registration of Foreign Limited Liability Company (Filing F0200) with the Mississippi Secretary of State, Business Services, and that is all.
Include with it certificate of good standing or existence dated at most 180 days.
What is due once the LLC is registered?
You keep filing the Foreign LLC annual report, at $250.
The due date, in the state's words, is April 15.
Why is the first pick first?
How much work the price handles counts for 28%, and Mainstay Filing comes out ahead on it.
Five criteria set the order: what three years cost (34%), how much work the price handles (28%), prices spelled out (16%), renewal terms (12%) and reach beyond one state (10%).
The home state needs an agent as well, and one account for both is simpler.
