Best-for picks with Missouri costs

  1. Best overall: Mainstay Filing ($597 over 3 years; $647 over 3 years with Missouri costs). One $199 price a year covers the formation filing, registered agent, EIN application and annual report, and it stays $199 at renewal.
  2. Lowest first-year cost: Bizee ($0 for year 1 with an agent; $348 over 3 years with Missouri costs). Its entry package is $0 plus the state fee and the registered agent is free for the first year when you form with it. Why
  3. Lowest three-year cost: Northwest Registered Agent ($289 over 3 years; $339 over 3 years with Missouri costs). A $39 package with the agent included the first year, then a $125 agent, adds up to the smallest service total over three years. Why
  4. Lowest agent price after year 1: Northwest Registered Agent ($125 a year from year 2; $339 over 3 years with Missouri costs). Its registered agent renews at the lowest rate of the five. Why
  5. Most included in one price: Mainstay Filing ($199 a year, all-in; $647 over 3 years with Missouri costs). Formation, agent, EIN application and annual report filing share one yearly price; the others sell the agent, EIN or report filing separately. Why
