Which form, and who gets it?
The form's the Application for Registration of Foreign Limited Liability Company (Filing F0200), and the Mississippi Secretary of State, Business Services gets it.
Attach certificate of good standing or existence no older than 180 days.
Is there a filing that repeats?
The state wants a Foreign LLC annual report later, and it's $250.
Per the state, it's due April 15.
Why this order?
Mainstay Filing scores best on jobs the price actually covers, and that test is worth 30%.
We run five tests: money out the door in three years (35%), jobs the price actually covers (30%), no hunting for the price (14%), no surprise at renewal (11%) and where it works (10%).
An out-of-state LLC already works in two states, and the first pick can cover both.
The last row is our math, not the state's: filing fee, plus the reports in years two and three, plus any minimum tax. If a cost has no fixed amount, like a newspaper notice, it's explained above and left out.
More questions
Do I still need an agent at home?
Each state sets its own rule, so keep an agent at home too. A provider that works in every state, like Mainstay Filing, can handle both.
What do the picks cost over three years?
Mainstay Filing will set you back $497, and Registered Agent MS.org will set you back $397, and Mississippi Registered Agent.co will set you back $397, with state fees on top.
Where do these numbers come from?
State fees come from Mississippi's official documents, and service fees come from each company's own price page. Both are dated here.
Is a service required?
Not required. The state takes filings from owners.
Can I pay somebody to register the LLC?
Yes. Every pick files it, and the state fee's the same whichever you choose.
Who's first in Mississippi?
Mainstay Filing is first: Mississippi's fee plus $199 gets you registered, and nobody bills you for the registered agent until year two. Then comes Registered Agent MS.org and Mississippi Registered Agent.co.
