To set up an LLC in Missouri, you file Articles of Organization with the Secretary of State, pay $50 online or $105 by paper, and then handle a short list of follow-ups: an operating agreement, a federal EIN, any state tax registrations that apply to your business, and an annual report every year after that. Online filings usually clear within a few business days; paper filings can take several weeks.
Pick a Name That Will Clear the State’s Database
Your name has to include “limited liability company,” “limited company,” or one of the abbreviations LLC, L.L.C., LC, or L.C. It cannot include words like “corporation,” “incorporated,” or “limited partnership” that suggest a different kind of entity.1Missouri Revisor of Statutes. Missouri Revised Statutes 347.020 – Name of Company Regulated
It also has to be distinguishable from every other business entity already on file with the Secretary of State, including corporations, limited partnerships, and other LLCs. Search the Secretary of State’s online business database before you commit. Swapping “and” for “&” or dropping “the” won’t be enough; the state strips out common articles and punctuation when it compares names.
If you’ve found a name but aren’t ready to file yet, you can reserve it for $25. The reservation runs 60 days and can be renewed twice, for up to 180 days total. After the third period expires, you can’t reserve that same name again.2Missouri Secretary of State. Starting a Business
Line Up a Registered Agent and Missouri Street Address
Every Missouri LLC needs a registered agent to receive lawsuits, government notices, and other official papers.3Missouri Revisor of Statutes. Missouri Revised Statutes 347.030 – Maintenance of Office and Agent for Service of Process The agent must be either a Missouri resident with a business office at the registered office address, or a business entity authorized to operate in the state.
The registered office has to be a physical street address in Missouri. P.O. boxes don’t qualify, because the state needs somewhere papers can be hand-delivered during business hours. You can serve as your own agent if you have a qualifying address, but that address becomes part of the public record. Professional registered agent services generally charge between $50 and $300 per year and solve the privacy problem for you.
File the Articles of Organization
The Articles of Organization (Form LLC-1) is what actually creates your LLC. You can download the paper form from the Secretary of State’s website or file online. The articles must include six items:4Missouri Revisor of Statutes. Missouri Code 347.039 – Articles of Organization Contents
- The LLC’s full legal name, with the required designation.
- The business purpose. Most filers use a general-purpose clause covering any lawful activity, which spares you from amending later if the business pivots.
- The registered agent’s name and the Missouri street address of the registered office.
- Management structure: member-managed (all owners participate in decisions) or manager-managed.
- Duration, which almost everyone sets to perpetual.
- The name and physical address of each organizer forming the LLC.
Paper filing costs $105, payable by check or money order to the Secretary of State, and goes to the Corporations Division at P.O. Box 778, Jefferson City, MO 65102.5Missouri Secretary of State. Articles of Organization – Form LLC-1 Online filing is $50 plus a small convenience fee and is substantially faster: online submissions typically process within a few business days, while paper filings can take several weeks depending on volume.
Once the state approves the filing, it issues a Certificate of Organization. Keep a copy. You’ll need it to open a business bank account and for various administrative tasks later.
Put an Operating Agreement in Writing
Missouri law says members “shall adopt” an operating agreement, and the statute gives you broad latitude over what goes in it. The state’s declared policy is to give “maximum effect to the principle of freedom of contract,” so the agreement can include almost any provision that doesn’t contradict Missouri law.6Missouri Revisor of Statutes. Missouri Code 347.081 – Operating Agreement
Even for a single-member LLC, this document matters. Without one, your LLC runs on Missouri’s statutory defaults for profit-sharing, voting, and dissolution, and those defaults may not match what you want. In a multi-member LLC, the operating agreement is where you record each owner’s capital contribution, how profits and losses get divided, what happens when a member wants out, and who can sign contracts or take on debt. Settling those terms in writing up front heads off expensive disputes later.
Banks routinely ask to see the operating agreement before opening a business account, and it works as evidence that your LLC operates as a genuine separate entity. That separation is what protects your personal assets. If a court decides you aren’t actually running the LLC as a distinct business, it can pierce the veil and hold you personally responsible for company debts.
Get Your EIN From the IRS
Once the LLC exists at the state level, apply for a federal Employer Identification Number from the IRS. You’ll need it to open a business bank account, hire employees, and file tax returns. The IRS recommends forming the entity with the state first; applying earlier can delay your EIN.7Internal Revenue Service. Get an Employer Identification Number
The fastest route is the IRS online application, which issues your EIN immediately. Whoever applies has to provide a Social Security Number or ITIN as the “responsible party,” meaning the individual who controls the entity’s funds and assets. There’s no fee.
Pick How the LLC Will Be Taxed
One of the real advantages of an LLC is tax flexibility. The IRS has no dedicated LLC category; it applies default rules based on how many members you have, and lets you elect something different.
A single-member LLC is treated by default as a disregarded entity, meaning the IRS ignores the LLC for income tax purposes and you report business income on Schedule C of your personal return. A multi-member LLC defaults to partnership taxation, where the LLC files an informational Form 1065 and each member gets a Schedule K-1 showing their share of profits and losses.8Internal Revenue Service. Single Member Limited Liability Companies
If neither default fits, you have two main alternatives. File IRS Form 8832 to be taxed as a C corporation, which puts profits through the corporate income tax and taxes distributions again as dividends.9Internal Revenue Service. About Form 8832, Entity Classification Election Or file IRS Form 2553 to elect S corporation status, which can reduce self-employment taxes for owners who pay themselves a reasonable salary, because only the salary portion is subject to payroll taxes. The S corp election has to be filed no later than two months and 15 days after the start of the tax year you want it to cover.10Internal Revenue Service. Instructions for Form 2553
Most small LLCs stay with the default, at least at first. If your profits are high enough that self-employment taxes become painful, talk to an accountant about whether an S corp election makes sense for you.
Register With the Missouri Department of Revenue
Your state tax obligations depend on what the business does. The Missouri Department of Revenue lets you register online for the tax types that apply, including sales tax, vendor’s use tax, consumer’s use tax, withholding tax, and corporate income tax.11Missouri Department of Revenue. Online New Business Registration
Selling physical goods or certain taxable services in Missouri requires a sales tax license. Hiring employees requires registering for withholding tax so you can remit state income tax from paychecks. The Department of Revenue’s online system handles both at once. Missouri doesn’t impose a general state-level business license, but many cities and counties do, so check locally about licenses or permits that apply to your location or industry.12Missouri Secretary of State. Steps for Starting a Business
Keep It Alive With the Annual Report
Every Missouri LLC has to file an Annual Registration Report to stay in good standing. The report is due each year during the anniversary month of your LLC’s formation. Form in March, and the report is due by the end of March every year after. The fee is $20 online or $45 on paper, and late reports carry an additional $15 penalty for each 30-day period they’re overdue.13Missouri Secretary of State. Schedule of Fees and Charges
The report itself is short. It updates the Secretary of State on your current management and registered agent information. If you skip it, the state can administratively dissolve your LLC, which strips your good standing and can expose owners to personal liability for obligations the business takes on after dissolution.14Missouri Secretary of State. Reinstate A calendar reminder for your anniversary month is the easiest way to avoid the whole problem.
