Start a Missouri LLC: A Step-by-Step Walkthrough

Before anything else, make sure the name you want isn't already taken. Missouri requires every LLC name to be distinguishable from the names of other business entities already on file with the Secretary of State, not just other LLCs, but corporations, limited partnerships, and any registered entity. "Distinguishable" is a legal test, and small differences like added punctuation, "the," or "and" often don't count as different enough.

Run your proposed name through the state's business entity name search. Search the exact name and a few close variations. If something similar already exists, the Corporations Division may reject your Articles, which costs you time.

Missouri naming rules

• The name must contain "limited liability company," "limited company," "LLC," "L.L.C.," "LC," or "L.C." (RSMo 347.020).
• It can't contain "corporation," "incorporated," "limited partnership," "limited liability partnership," "limited liability limited partnership," or "Ltd.," or their abbreviations.
• It must be distinguishable from all entity names already registered in Missouri.
• It cannot imply a purpose that isn't stated in the Articles.

Reserving a name

If you're not ready to file but want to hold the name, Missouri lets you reserve it for 60 days with Form BE 1 for $25. The reservation can be renewed for two more 60-day periods, up to 180 days in total. A reservation does not create the LLC. It just parks the name while you finish everything else. Most owners skip this and simply file once they're ready.

Missouri law requires every LLC to continuously maintain a registered office and a registered agent in the state (RSMo 347.030): the official recipient for legal service of process and state correspondence. At formation you simply name the agent and the agent's Missouri address in item 3 of the Articles of Organization.

The registered office needs a physical Missouri street address. Form LLC 1 allows a P.O. box only if a street address is also given, and the Secretary of State's FAQ says the street address has to be in the same city. Later changes go on Form Corp 59, the Statement of Change of Registered Agent and/or Registered Office, which costs $10; the new agent signs it or attaches a written consent.

Who can serve

• Yourself: If you're a Missouri resident and your business office serves as the registered office, you can be your own agent. Your address becomes public record.
• Another individual: Any Missouri resident whose business office is the registered office, such as a co-owner, employee, or trusted contact.
• A corporation: A domestic or foreign corporation authorized to do business in Missouri, with its business office at the registered office. Commercial registered agent services typically serve this way, and they keep the service's address in the public record instead of yours.
• Not the LLC itself: the LLC isn't on the statute's list of eligible agents.

Why it matters

If you list your home as the registered agent address, it becomes searchable in the public business database, and process servers can show up there. A commercial service keeps your address private and makes sure a lawsuit or a state notice never goes unaccepted because you happened to be out.

The Articles of Organization (Form LLC 1) is the filing that legally creates your Missouri LLC. The efficient way to file is online through Missouri Business Filings, where the fee is $50, paid by credit card, and you'll need an email address. The paper form costs $105 and is mailed to the Corporations Division at P.O. Box 778 in Jefferson City. Card and e-check payments carry a small state convenience fee. The fee schedule and forms are posted on the Corporations Division site.

The Secretary of State says many online filings are processed immediately after submission, after which your entity shows up in the state database and your stamped Articles become available. There's no expedite fee on the state's schedule.

What the Articles include

• LLC name with the required designator ("LLC," "L.L.C.," etc.)
• Purpose: A general-purpose statement is acceptable. You don't have to pin yourself to one activity.
• Registered agent name and Missouri address
• Management: Whether management is vested in the members or in managers
• Duration: The events on which the LLC dissolves, or the number of years it's to continue
• Organizers: The name and street address of each organizer; all organizers sign (they don't have to be members)
• Optional items: Series provisions and a principal office address

What you don't have to disclose

Missouri doesn't ask you to name every member, state ownership percentages, or reveal any financials in the Articles. Those internal details live in your operating agreement and stay private.

The operating agreement is your LLC's internal rulebook. Missouri doesn't make you file it with the state, but RSMo 347.081 says the members "shall adopt" one, and the Act counts written or oral agreements. A written version is the one worth having, especially with partners. This document controls how your company actually runs and settles disputes before they start.

What a solid operating agreement covers

• Ownership: Who the members are and what percentage each holds
• Capital contributions: What each member put in, and any obligation to contribute more later
• Profit and loss allocation: How money is split, usually by ownership, but it doesn't have to be
• Distributions: When and how cash is paid out to members
• Management: Who runs things day to day and which decisions require a member vote
• Voting: Whether votes are weighted by ownership or counted per member
• Transfers: What happens when a member wants to sell or leave: rights of first refusal, buyout terms
• Dissolution: How the company winds down and distributes what's left

For a single-member LLC, the agreement helps prove the company is a separate entity, which supports your liability shield. For a multi-member LLC it's essential. Without it, Chapter 347's statutory defaults decide everything, and they may not match your intentions.

An Employer Identification Number is a nine-digit federal tax ID the IRS issues for free. It's the business version of a Social Security number, used on tax filings, when opening bank accounts, and when hiring.

When you need one

• Your LLC has more than one member (multi-member LLCs must file a partnership return)
• You plan to hire employees
• You want a business bank account (nearly every bank requires an EIN)
• You've elected S-corp or C-corp tax treatment

A single-member LLC with no employees can technically use the owner's Social Security number for federal taxes, but getting an EIN anyway keeps your SSN off business paperwork and simplifies banking.

How to apply

Apply online at IRS.gov. The application takes about ten minutes and the number is issued instantly, so you can use it the same day. You'll need a US SSN or ITIN to apply online; applicants without one file Form SS-4 by fax or mail. If you form through Mainstay, we apply for the EIN for you after the Articles are filed. The number itself is free either way.

Keeping business and personal money separate isn't just tidy. It's what preserves your liability protection. If you run personal expenses through the LLC account or deposit business income into a personal account, a court can decide the LLC isn't really separate from you and hold you personally liable.

What banks usually want

• Your filed Articles of Organization
• Your IRS EIN confirmation
• Your operating agreement (many banks ask for it)
• Government-issued ID for each authorized signer

Missouri community banks and credit unions are often friendlier to brand-new LLCs than the big national chains, and several online business banks can open an account without a branch visit. Weigh the monthly fees, transaction caps, and required minimum balances against each other before settling on one.

Here's the good news about Missouri: after formation, there's very little the state asks of you.

No annual report

Missouri LLCs have no annual report and no franchise tax. The Secretary of State's FAQ answers the question directly: LLCs do not have to file an annual report. There is no yearly state filing to keep your LLC in good standing, a genuine break from most states. You do not need to calendar an annual state deadline for the LLC itself.

Registered agent upkeep

You must keep a valid registered agent on file at all times. If your agent moves, resigns, or you switch providers, file Form Corp 59 ($10) with the Secretary of State promptly so your record stays current and legal service can reach you.

Taxes

Federal treatment depends on your setup: single-member LLCs file Schedule C, multi-member LLCs file Form 1065, and S-corp elections file Form 1120-S. Missouri income tax applies to pass-through profits on your state return. If you sell taxable goods or services, register for sales tax with the Missouri Department of Revenue.

Licenses and permits

Missouri has no single statewide general business license, but many professions and many cities and counties require their own licensing. These run on separate schedules and are unrelated to your Secretary of State filing.
