How to Form an LLC in Missouri

How to Form an LLC in MissouriA Missouri Limited Liability Company (LLC) is a legal structure used to protect your personal assets (home, car, bank account) in the event your business is sued.

An LLC can be used to operate a business, or an LLC can be used to hold assets (such as real estate, vehicles, boats, or aircraft).

Forming an LLC in Missouri is simple. Search your desired Missouri LLC name and designate your Registered Agent.

File your LLC Articles of Organization and pay the state filing fee ($50 if filed online, $105 if filed by mail).

After your Missouri LLC is approved, complete your Operating Agreement and get your Federal Tax ID Number from the IRS.

    I filed a 2 member llc (to run a campground) a few weeks ago, my daughter and myself, and this week she decided she did not want to be a partner. I have not filed for a federal tax number yet since we are still writing our operating agreement. What steps do I need to take to change the llc from a partnership in Missouri to a sole proprietorship?

      Hi Trudi, careful with your language. The only mention of Sole Proprietorship or Partnership takes place with the IRS and the Department of Revenue. With the Secretary of State (and in terms of state law), your LLC is simply an LLC. They don’t care about how the LLC files taxes. (Related article: how are LLCs taxed). The Missouri LLC Articles of Organization also doesn’t ask for Member info, so you actually don’t have to file anything with the Secretary of State. Instead, you’d just apply for your EIN and enter 1 Member. That is how your LLC will be taxed as a Sole Proprietorship by the IRS. And you’ll just create a new Operating Agreement showing you’re the sole owner. Hope that helps!

    My HOA here in Missouri operates under a manager-managed LLC and lists managers as President, VP, Treasurer and Secretary. The term of our Secretary expired and a new Secretary was elected. What MO form needs to be submitted to note the name change of our Secretary?

      Hi Jim, when the LLC was filed, was the state’s Articles of Organization form used? If so, Managers aren’t listed there. Instead, they’d be listed in the LLC’s Operating Agreement, so you’d just need to amend the Operating Agreement. You can also create meeting minutes and an LLC Resolution about the change of Secretary. Hope that helps.

    I have a single member llc. How do I make it a multi member so I can add my wife? I am in Missouri.

    • Matt Horwitz October 25, 2018

      Hi Dayton, since no LLC Members get listed in the Missouri Articles of Organization, you don’t have to file an Amendment with the Secretary of State. Instead, amend your Operating Agreement or create a new Operating Agreement with you and your wife. Then you can either mail a letter to the IRS notifying of the change in taxation (LLC taxed as a Sole Proprietorship is now going to be taxed as a Partnership since a new Member was added), or you can complete IRS Form 8832 and elect Partnership taxation that way. Hope that helps.
