To form an LLC in Missouri, file articles of organization with the Missouri Secretary of State. The filing fee is $50 online or $105 by mail, and the filing officially creates the company.1Missouri Secretary of State. Schedule of Fees and Charges Before and after that filing you need to pick a compliant name, name a registered agent in Missouri, decide how the company will be managed, get a federal EIN, and put an operating agreement in place. None of it is complicated, but the order matters and a few of the choices are hard to change later.
Pick a Name That Meets Missouri’s Rules
Your company name has to include “Limited Liability Company,” “Limited Company,” or one of the accepted abbreviations: “LLC,” “L.L.C.,” “LC,” or “L.C.”2Missouri Revisor of Statutes. Missouri Code 347.020 – Name of Company Regulated It cannot use words like “corporation,” “incorporated,” or “limited partnership” that suggest a different kind of entity, and it has to be distinguishable from the name of any corporation, LLC, or limited partnership already on file in Missouri.
Check availability through the Secretary of State’s online business search before you get attached to a name or print anything.3Missouri Secretary of State. Business Services If your first choice is taken, adjusting a word or adding a descriptor is usually enough to clear the distinguishability test.
File the Articles of Organization
The articles of organization are the document that legally creates the LLC. You file them with the Missouri Secretary of State, online or on paper. Online is $50; paper is $105.1Missouri Secretary of State. Schedule of Fees and Charges
The form asks for:4Missouri Secretary of State. LLC 1 – Articles of Organization
- The LLC’s name, following the Section 347.020 rules.
- A brief description of the business purpose.
- The name and physical street address of the registered agent.
- Whether the LLC will be managed by its members or by designated managers.
- The duration of the LLC (which can be perpetual) or the events that will trigger dissolution.
- The name and street address of each organizer.
You can also list a principal office address and, if it fits your setup, designate the entity as a series LLC under Section 347.186. The filing is effective on the date the Secretary of State processes it unless you set a future effective date up to 90 days out.
Name a Registered Agent in Missouri
Every Missouri LLC has to continuously maintain a registered agent and registered office in the state.5Missouri Revisor of Statutes. Missouri Code 347.030 – Registered Office and Agent Requirements That’s the person or company authorized to accept lawsuits, government notices, and other official documents for your LLC.
An individual serving as registered agent has to be a Missouri resident whose business office address matches the registered office address. A business entity can serve if it’s authorized to operate in Missouri and maintains a business office at the registered office address. The registered office must be a physical Missouri street address, not a P.O. box. Plenty of LLC owners act as their own registered agent. Professional registered agent services are worth the fee if you don’t want your home address in public records or you can’t reliably be present during business hours.
Choose Member-Managed or Manager-Managed
The management choice goes on the articles of organization itself, so decide before you file.
In a member-managed LLC, every member helps run the business and vote on decisions. It fits small companies where all the owners are actively involved. Without a different rule in the operating agreement, decisions default to majority vote.6Missouri Revisor of Statutes. Missouri Code 347.079 – Management of Company
In a manager-managed LLC, one or more designated managers run operations. Managers can be members, outside hires, or other entities. This suits companies with passive investors who want returns without operational responsibility, and larger operations that benefit from centralized decisions. A member who isn’t a manager owes no fiduciary duties to the company or the other members solely because of their member status, which is one reason passive-investor structures often go this route.7Missouri Revisor of Statutes. Missouri Code 347.088 – Standard of Duty
Write an Operating Agreement
Missouri statute directs that LLC members “shall adopt” an operating agreement, and the law explicitly favors giving “maximum effect to the principle of freedom of contract.”8Missouri Revisor of Statutes. Missouri Code 347.081 – Operating Agreement, Contents No state agency checks whether you actually wrote one. But if you don’t, your LLC runs on statutory defaults, and those defaults rarely match what any specific set of owners would have chosen.
The statute lets members write in provisions covering:
- Who manages the LLC, what powers they have, and how decisions get made.
- Different classes of members with varying rights, voting power, or financial entitlements.
- Meeting notice, quorum, proxy voting, and action by written consent without a meeting.
- Restrictions on selling or assigning a membership interest, and buyout terms when a member leaves.
- How income, gains, losses, and deductions are allocated among members.
- Which federal tax elections the LLC will make and who can make them.
The allocation piece is where owners who skipped the agreement tend to get surprised. If the operating agreement is silent, Missouri’s default rule for profits first offsets any losses previously allocated, then follows the pattern of distributions that exceeded contribution repayments. Losses default to allocation based on each member’s contributions, made and promised.9Missouri Revisor of Statutes. Missouri Code 347.111 – Allocation of Profits or Losses Members who assumed everything would be split evenly can end up with a very different result.
Single-member owners still benefit from an operating agreement. It documents that the LLC is a separate entity from you personally, which strengthens the liability shield.
Get an EIN and Handle Tax Setup
Once the Secretary of State has filed your articles, apply to the IRS for an Employer Identification Number. You need it to open a business bank account, hire employees, and file federal returns for the LLC.10Internal Revenue Service. Employer Identification Number The IRS recommends forming your entity with the state before applying, because applying first can cause delays.11Internal Revenue Service.

By default, a single-member LLC is a disregarded entity for federal tax (reported on the owner’s personal return), and a multi-member LLC is taxed as a partnership. No entity-level federal tax applies; income passes through to the members. You can elect corporate treatment by filing IRS Form 8832, or S corporation treatment by filing Form 2553.12Internal Revenue Service. About Form 8832, Entity Classification Election13Internal Revenue Service. About Form 2553, Election by a Small Business Corporation An S corp election can reduce self-employment tax for owners who also work in the business, but it has eligibility limits on the number and type of shareholders, so it doesn’t fit every LLC.
At the state level, Missouri generally follows the federal pass-through treatment. Members owe Missouri individual income tax on their share of company income, and the Missouri Department of Revenue handles state tax registration.
Local Licenses and What Missouri Does Not Require
Check whether your city or county requires a local business license or permits before you start operating. Requirements and fees vary by jurisdiction.
Missouri does not require LLCs to publish a notice of formation in a newspaper. Publication rules in the Missouri LLC statute apply to disposing of unknown claims during dissolution, not to starting up.
Once you’re operating, keep business finances separated from personal accounts. Commingling funds is one of the easiest ways to lose the liability protection an LLC exists to provide.
What You Have to Keep Up With Each Year
Unlike Missouri corporations, LLCs don’t have to file an annual registration report with the Secretary of State. There is no recurring state filing or fee just to stay in good standing. You do still have to keep a registered agent in place and keep your Secretary of State information current, but there is no annual paperwork deadline waiting to trip you up.
