1. Registered Agent MS.org: best for an economical registration

$199 to register, $99 per year afterward

On three-year cost it undercuts Mainstay Filing, and cost is a large part of the ranking.

2. Mainstay Filing: best for a second state and later ones

Handles the most paperwork
$199 to register, $149 per year afterward

Mainstay Filing is ranked second: a charge of $199 plus Mississippi's fee covers the filing and the first year of the registered agent.

A three-year difference of $100 from Registered Agent MS.org sets its position.

Beyond year one the agent is billed at $149 a year, whichever state applies.

How registration works in Mississippi

  1. Section 1

    When Mississippi requires registration

    Foreign registration is the filing by which an LLC formed outside Mississippi is authorized to do business in Mississippi. Penalties for ignoring the rule include: the courts of Mississippi are closed to its claims until it registers (Miss. Code Ann. 79-29-1013(1)) existing contracts keep their force (Miss. Code Ann. 79-29-1013(2)) a per-day fine of $10.

  2. Section 2

    Get proof of good standing from the state of formation

    Mississippi requires certificate of good standing or existence, issued no earlier than 180 days.

    Order this last so the certificate is current when you file.

  3. Section 3

    Select the Mississippi registered agent

    Every LLC must name a registered agent with an in-state street address. The address has to be a physical Mississippi street address that is the agent's business office. P.O. boxes are not accepted.

    The recommended reading covers this role.

    Reference: Reference: sos.ms.gov, consulted October 2026

  4. Section 4

    The state wants the Application for Registration of Foreign Limited Liability Company

    Filing is the act of registering, and the state charges $250.

    Reference: Reference: sos.ms.gov, consulted October 2026

  5. Section 5

    Remain registered

    Note the Foreign LLC annual report and its $250 fee (April 15).

Costs section by section

SectionPayeeAmount
Registration fee Filing office$250
Foreign LLC annual report Filing office$250
Filing service (optional) The provider$199 in year one
State fees for the first three years Filing office$750

Rows for the state rely on Mississippi's published fee schedules (listed in the bibliography below), and each service row uses that company's own price. For three years the state row adds the filing, the report in year two, the report in year three and any minimum tax.

How the ranking came out

The deciding criterion was tuition over three years, which carries 34% of the ranking.

A three-year total of $397 for Registered Agent MS.org, which is $100 below Mainstay Filing, explains the order.
