Missouri foreign registration service pricing in 2026: first year, renewals, three-year total
Every price comes from the company's own pages as of November 12, 2026. The $105 Missouri registration fee comes on top of each row and is left out of the totals.
Why Missouri Registered Agent.co is first
Filing Shortlist puts 28% of the weight on three-year price and 28% on what the price covers. The remaining 44% goes to renewal terms, fit for the state and price clarity, and for Missouri the deciding factor was three-year price.
Missouri Registered Agent.co adds up to $397 over three years, which is $100 below Mainstay Filing. Both services include year one, which left the renewal price to settle the order.
Every criterion and weight is set out on How we rank.
Registering a foreign LLC in Missouri: fee, form and office
Registration goes to the Missouri Secretary of State, Corporations Division on the Application for Registration of a Foreign Limited Liability Company (Form LLC 4). The state fee is $105.

Missouri does not ask foreign LLCs for a yearly report.
What to have ready before you file
- Certificate of good standing/existence from the home state, dated within 60 days of filing.
- The company's exact legal name and its formation date in the home state.
- A registered agent at a street address in the state. Every company on this shortlist can be that agent.
- Payment of the $105 state fee with the filing.
