The primer, move by move

  1. Move 1

    Name the company

    A taken name can get the Mississippi filing bounced. Run the business search at the Mississippi Secretary of State before you do anything else.

    Look up the matching domain at the same time.

  2. Move 2

    Choose 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.

    The registered agent job comes with each pick.

  3. Move 3

    DIY or hire help

    DIY costs the $50 state fee and your time. A service adds $199 and does the forms; our ranking says which.

  4. Move 4

    Finish and lodge the Certificate of Formation

    Send the Certificate of Formation (Form F0100) and $50 to the Mississippi Secretary of State. Legal basis: Miss. Code Ann. § 79-29-201. That brings the LLC into being.

    Where this comes from: Official page: sos.ms.gov (August 2026)

  5. Move 5

    Sort out the EIN

    The IRS issues EINs, not Mississippi. Apply after approval and hand the number to your bank. Mainstay Filing does this for you, no extra fee.

  6. Move 6

    Draft the operating agreement

    Owners sign it to settle shares, votes and what happens when someone leaves. It is private and never filed.

  7. Move 7

    Handle Mississippi's recurring filing

    What repeats is the annual report (no fee, every year, by April 15).

Short answers

How big is the Mississippi formation fee?

Which form creates the LLC?

Once the Mississippi Secretary of State accepts the Certificate of Formation (Form F0100), the LLC exists.

Is a registered agent required?

Every LLC must name a registered agent with an in-state street address.

What does Mississippi require each year?

The repeating item is the annual report (no fee, every year, due April 15).

Can I form the LLC without a service?

Yes. Pay the state $50 at filing; the LLC still needs a registered agent.

Registered Agent MS.org first, then Mainstay Filing and Mississippi Registered Agent.co; Registered Agent MS.org wins on founder outlay over three years.
