To get an LLC in Missouri, you file Articles of Organization with the Secretary of State and pay $50 online or $105 by mail. Online filings are usually processed within minutes. Before you file, pick a compliant name and line up a registered agent; after you file, Missouri law requires you to adopt an operating agreement, and you’ll likely need an EIN and one or more tax registrations before you start operating.
Pick a Name That Will Clear the State’s Records
Your LLC name has to end with one of the approved designators: “Limited Liability Company,” “Limited Company,” “LLC,” “L.L.C.,” “LC,” or “L.C.” It cannot include “corporation,” “incorporated,” “limited partnership,” or their abbreviations, and it cannot suggest a government agency or a purpose your Articles don’t authorize.1Missouri Revisor of Statutes. Missouri Revised Statutes Section 347.020
The name also has to be distinguishable on the Secretary of State’s records from every other corporation, LLC, or limited partnership already registered in Missouri. An existing entity can consent to a similar name in writing, but only by filing paperwork to change its own name. There’s no way around the distinguishability rule if the name you want is truly taken.1Missouri Revisor of Statutes. Missouri Revised Statutes Section 347.020
Search the Secretary of State’s online business database first. If you find a name you like but aren’t ready to file, you can reserve it for $25. The reservation lasts 60 days and can be renewed twice, for up to 180 days of exclusive rights.2Missouri Secretary of State. Starting a Business
Line Up a Registered Agent
Every Missouri LLC must continuously maintain a registered agent and a registered office in the state. The agent receives lawsuits and official notices on the LLC’s behalf. It can be a Missouri resident or a domestic or foreign corporation authorized to do business in Missouri, and the agent’s business office must sit at the same street address as the registered office.3Missouri Revisor of Statutes. Missouri Revised Statutes Section 347.030
A P.O. box does not satisfy the statute; you need a street address where the agent is reachable during normal business hours. Many owners serve as their own agent, which is legal if you have a Missouri street address and are reliably there during the day. Commercial registered agent services typically run $75 to $300 per year.
To change the agent or office later, file a Statement of Change (Form Corp. 59). The change takes effect once processed.3Missouri Revisor of Statutes. Missouri Revised Statutes Section 347.030 If the position goes vacant and you don’t fix it in time after the Secretary of State notifies you, your LLC’s registration can be cancelled.4Missouri Secretary of State.

File the Articles of Organization
The Articles of Organization (Form LLC 1) is the document that legally creates your LLC. Filing online costs $50 and is typically processed within minutes. Paper filing costs $105 and can take several weeks depending on the office’s workload.5Missouri Secretary of State. Schedule of Fees and Charges6Missouri Secretary of State. Frequently Asked Questions
The form asks for the LLC’s full name with designator, its purpose (general business or a specific professional activity), the management structure (member-managed or manager-managed), the registered agent’s name and Missouri street address, the organizer’s name and address, the duration (perpetual or a specific end date), and the effective date. You can make the LLC effective immediately or set a future effective date up to 90 days out.7Missouri Secretary of State. LLC 1 – Articles of Organization
One detail that trips people up: the organizer who signs the Articles doesn’t have to be a member or manager. Anyone can serve as organizer. After formation, though, filings with the Secretary of State must be signed by a manager (if manager-managed) or a member (if member-managed).6Missouri Secretary of State. Frequently Asked Questions
Once the state approves and stamps the filing, that stamped copy is conclusive evidence the LLC exists. The LLC can’t transact business or take on debt until the Articles are filed or the future effective date arrives.
Adopt an Operating Agreement
Missouri is unusually direct here. The statute says members “shall adopt” an operating agreement, so it isn’t optional, even though the Secretary of State never sees the document.8Missouri Revisor of Statutes. Missouri Revised Statutes Section 347.081
The operating agreement is a private contract among the members that governs the internal life of the business: voting rights, how profits and losses are split, how ownership interests get transferred, how new members are admitted, and how the LLC winds down if the members decide to close it.
Single-member LLCs need one too. Without an agreement, Missouri’s default statutory rules fill the gaps, and those defaults may not match what you’d actually want. Banks and business partners will also ask to see the agreement when they need to confirm who has authority to act for the LLC.
Get an EIN and Decide How the LLC Will Be Taxed
After the state approves your LLC, apply for a Federal Employer Identification Number from the IRS. The EIN is required to open a bank account, hire employees, and file tax returns. You can apply online at irs.gov at no cost, and the IRS recommends forming the entity with the state before applying.9Internal Revenue Service. Get an Employer Identification Number
Federal tax treatment depends on how many members you have. A single-member LLC is a “disregarded entity” by default, meaning business income flows onto your personal return. A multi-member LLC is treated as a partnership by default, filing Form 1065 and issuing K-1s to each member.10Internal Revenue Service. Entities 3
You can override those defaults. Form 8832 elects C corporation taxation. Form 2553 elects S corporation status, which can reduce self-employment taxes for owners who pay themselves a reasonable salary. The deadline for an S-corp election is no more than two months and 15 days after the start of the tax year you want it to cover, so decide early.11Internal Revenue Service. Instructions for Form 2553
Register for State and Local Taxes
Your LLC must register with the Missouri Department of Revenue if it will collect sales tax, withhold income tax from employees, or owe corporate income tax. The Department of Revenue and the Division of Employment Security run a combined online registration that covers sales tax, vendor’s use tax, consumer’s use tax, withholding tax, unemployment tax, and corporate income tax in one process.12Missouri Department of Revenue. Online New Business Registration
If you sell tangible goods or certain taxable services, you need a sales tax license before making any sales.13Missouri Department of Revenue. Business Tax Registration Missouri does not impose a blanket state business license, but many cities and counties require their own local business licenses and permits. Check with the municipality where you’ll operate, because requirements vary significantly by location.14Missouri Secretary of State. Steps for Starting a Business
Keep the LLC in Good Standing
Missouri requires LLCs to file registration reports with the Secretary of State. The fee is $20 online or $45 by mail. Some LLCs qualify to file biennially instead of annually; the online filing portal will tell you which cycle applies to your entity.5Missouri Secretary of State. Schedule of Fees and Charges15Missouri Secretary of State. Annual and Biennial Registration Reports
Skipping the report has real consequences. Failure to file can lead to administrative dissolution of a domestic entity or cancellation of your LLC’s registration, and the same applies if you let the registered agent or office lapse.4Missouri Secretary of State. General Services and Filings When a bank, landlord, or another state’s registration office asks for a Certificate of Good Standing, the Secretary of State issues one for $10.5Missouri Secretary of State. Schedule of Fees and Charges
If You’re Considering a Series LLC
Missouri also allows a Series LLC, which lets one LLC create separate “series” that each hold their own assets, liabilities, and members. Done correctly, the debts of one series can’t reach the assets of another series or the parent LLC. Real estate investors and businesses that want to compartmentalize risk often use this structure instead of forming several separate LLCs.16Missouri Revisor of Statutes. Missouri Revised Statutes Section 347.186
The liability shield only holds if every statutory requirement is met. The operating agreement must create the series and provide for limited liability. Each series must keep separate records and separately account for its assets. The Articles of Organization must give notice that the series has limited liability and must identify each series by name, which has to contain the full name of the parent LLC. Each series also files its own attachment (Form LLC 1A) with the Secretary of State.7Missouri Secretary of State. LLC 1 – Articles of Organization16Missouri Revisor of Statutes. Missouri Revised Statutes Section 347.186 An individual series can be dissolved without shutting down the parent or the other series. The recordkeeping rules are strict, and commingling assets between series can destroy the protection.
