Researched and written by the Formation Scorecard editorial team
Rank #1 Our top pick

1. Mainstay Filing: best for one all-in yearly price

9.1 Editor score out of 10
$199 a year plus the state's fee, $249 due at checkout

Mainstay Filing leads the card: the formation and the registered agent come in one $199 yearly price that renews at $199.

With no yearly LLC report in Missouri, the renewal after year one mostly buys the registered agent, since the EIN application belonged to the first-year bundle.

Mainstay's three-year total sits $200 above Missouri Registered Agent.co's, which the extra coverage earns back in our scoring.

Missouri LLC service cost in 2026: first year, renewal and the three-year tally

Service First year Second year Third year Three-year tally EIN application
Mainstay Filing $199 $199 $199 $597 Included
Missouri Registered Agent.co $199 $99 $99 $397 $99 add-on
MO Registered Agent.org $199 $99 $99 $397 $99 add-on

Each price comes from the company's own site, read on November 12, 2026. Add Missouri's $50 filing fee to each row; the tally above leaves it out.

Why the order falls this way

Formation Scorecard scores cost across three years and coverage of the price at 25% each. Renewal terms, state-by-state fit and pricing clarity account for the other 50%. In Missouri the tie was broken by coverage of the price.

Missouri has no yearly report to file, which shrinks the bundle's edge, yet one fixed price with the EIN application included still outscored Missouri Registered Agent.co on coverage.

Every criterion and weight appears on How we rank.
