By the Biz Formation Report editorial team

Biz Formation Report ranks LLC services in Missouri for 2026 as Mainstay Filing ($199), MO Registered Agent.org ($199) and Missouri Registered Agent.co ($199), in that order. Mainstay Filing earns the top grade: one yearly price of $199 handles the formation and the registered agent, renewing at $199.

No.1

Top pick on this page

1. Mainstay Filing: best for one flat yearly price

Score9.3out of 10
$199 a year plus the state fee, $249 due at checkout

Top grade, Mainstay Filing: $199 covers the Missouri formation and a year of registered agent service, EIN application included.

Missouri has no yearly LLC report, so past year one the renewal is paying for the registered agent alone (the first-year bundle had also covered the EIN application).

Over three years Mainstay costs $200 more than MO Registered Agent.org; our grading treats the broader coverage as worth that.

All prices were taken from the companies' own websites on November 12, 2026. Missouri's $50 filing fee is payable on top of each row and is not part of these totals.

Why the order falls this way

The grading method assigns 32% to three-year bill and 32% to what the money buys, with renewal handling, local rules match and pricing openness taking 36%. For Missouri, what the money buys decided it.

Missouri requires no yearly report, so the bundle counts for less; one fixed price with the EIN application included still graded above MO Registered Agent.org on coverage.
