Spot 1

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

$199 each year plus the state fee ($249 due at checkout)

9.2Editorial score
out of 10

Mainstay Filing wins here: $199 a year covers the Missouri filing and your registered agent, plus the EIN application, and it renews at $199.

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

The three-year bill is $200 higher than MO Registered Agent.org's, and the wider coverage is worth that to us.
