What Missouri charges you to register a foreign LLC and what it requires

Out-of-state LLCs doing business in Missouri send $105 and the Application for Registration of a Foreign Limited Liability Company (Form LLC 4) to the Missouri Secretary of State, Corporations Division. Include certificate of good standing/existence from the home state dated within 60 days.

If you never register, expect Missouri courts refusing to hear your own lawsuits (RSMo 347.163.1).

The state's wording: dor.mo.gov (we looked on October 2026, so you can too)

What it costs without a service

Doing it yourself costs $105 paid to the state across three years. A service at $397 to $497 is what you pay to skip the forms.
