Best grade

1. Mainstay Filing: best for new founders who want it handled

$199 a year plus the state fee ($249 at checkout)

First in the class in Mississippi is Mainstay Filing: three chores, the filing, the registered agent and the annual report, are folded into a single $199 annual price.

Over three years it costs $200 more than Registered Agent MS.org, but the grade rewards the extra steps it takes care of.

The annual report, which has no fee, is filed for you.

What the price covers

  • The filing is done for you
  • Registered agent for twelve months
  • Annual report prepared and filed
  • The EIN application
  • State fee added at cost

Marks in its favor

  • One yearly price of $199, with the annual report included
  • $199 at renewal
  • No extra charge for the EIN application

Where it loses points

  • Registered Agent MS.org renews for $100 less

2. Registered Agent MS.org: best for an inexpensive Mississippi start

$199 to start, $99 a year from year two

You file the annual report on your own every year.

Its prices equal Registered Agent MS.org's, so either is a sound choice.

Starting an LLC in Mississippi, one step at a time

  1. Step
    1

    Come up with a name

    Type the name into the business search at the Mississippi Secretary of State before you file anything, so you do not pick one that is in use.

    Jot down two backup names before you search.

  2. Step
    2

    Name a registered agent

    Every LLC must name a registered agent with an in-state street address. Any individual, corporation or LLC with a physical address in Mississippi. Agents that serve for hire register with the Secretary of State as commercial agents.

    The address has to be a physical Mississippi street address that is the agent's business office. P.O. boxes are not accepted.

    All of our picks fill the registered agent role.

  3. Step
    3

    Decide: do it yourself or hire help

    Doing it yourself means $50 to the state and nothing else. One of our picks charges $199 on top and takes over the paperwork.

  4. Step
    4

    Prepare and file the Certificate of Formation

    The Certificate of Formation (Form F0100) is what you prepare for the Mississippi Secretary of State, and the filing fee that goes with it is $50, as Miss. Code Ann. § 79-29-201 provides.

    Where this comes from: The official page is sos.ms.gov, last confirmed in August 2026

  5. Step
    5

    Get your EIN from the IRS

    With the Mississippi approval in hand, ask the IRS for an EIN so the LLC can open accounts in its own name. If you hire Mainstay Filing, it files the EIN application for you.

  6. Step
    6

    Sign an operating agreement

    Think of the operating agreement as the LLC's rulebook: who owns what, kept by you and not sent to the state.

  7. Step
    7

    Keep up with Mississippi's recurring filing

    File the annual report every year, by April 15, and the LLC stays active.
