Researched and written by the Launchwise Review editorial team
For a 2026 launch in Missouri, Launchwise Review grades LLC services this way: Mainstay Filing ($199), Missouri Registered Agent.co ($199) and MO Registered Agent.org ($199). Mainstay Filing earns the top grade here: for $199 you get the Missouri formation and a year of registered agent service, with the EIN application added in.

Our top pick

1. Mainstay Filing: best for one flat yearly price for the whole launch

$199 yearly, state fee billed on top ($249 at checkout in all)

Our mark 9.5 out of 10

Top grade, Mainstay Filing: $199 a year handles the Missouri filing and the registered agent and your EIN application, renewing at $199.

Missouri has no yearly LLC report to file, so after year one you are paying for the registered agent alone (year one also covered your EIN application).

It runs $200 above Missouri Registered Agent.co across three years; the extra paperwork it handles is worth that to us.

In the price

  • Formation paperwork prepared and sent in
  • A full year as your registered agent
  • Your EIN application, done for you

Pros

  • Renews at $199 without add-ons
  • Missouri's fee goes through at cost
  • Your EIN application is included
  • A single $199 yearly price

Less good

  • After year one the agent portion is $100 a year above Missouri Registered Agent.co's
  • Missouri has no yearly report, so the bundle gives less

What drove the grades

At Launchwise Review, cost to launch and stay and launch paperwork handled each count for 26% of a grade, and renewal behavior, state match and price transparency split the remaining 48%. In Missouri, launch paperwork handled made the call.

Missouri has no yearly report, so a bundle matters less, but one fixed price that includes your EIN application still nudged Missouri Registered Agent.co aside on coverage.

Every criterion and weight is listed on How we rank.

Launching in Missouri: the state filing fee and form

Plan on $50 at the Missouri Secretary of State when you file the Articles of Organization (Form LLC-1). Each company below adds that state fee at cost.

Your Missouri LLC after launch: the upkeep list

Nothing recurs here: Missouri has no yearly LLC report. Every LLC must name a registered agent with an in-state street address.
