Forming an LLC in Missouri takes 5 steps: choose and check your business name, appoint a Registered Agent with a physical Missouri address, file Articles of Organization online or by mail, adopt an operating agreement (which Missouri law actually requires), and get an Employer Identification Number (EIN) from the IRS. The state filing fee is $50 online.
Missouri’s pitch is simple: after the one-time $50 online filing, the state never charges your LLC again — no annual report, no renewal, no franchise tax, nothing. Only a handful of states run this way, and it makes Missouri one of the cheapest places in the country to keep a company alive long-term. An LLC gives you personal liability protection and pass-through taxation without the administrative overhead of a corporation.
The tax treatment is friendlier than the headline rate suggests, too: on top of the federal QBI deduction, Missouri lets owners deduct 20% of pass-through business income on their state return, pulling the effective state rate on LLC profits under about 3.8% — and the top rate itself (4.7% in 2026) is on a legislated path downward. Since 2025, Missouri even exempts individual capital gains from state income tax, a nice bonus if you eventually sell business assets.
Unlike some states, Missouri doesn’t require you to reserve your name before filing — you simply claim it when you file your Articles of Organization. If you’re not ready to file yet, you can optionally reserve a name for $25 for 60 days, renewable twice for 60 days each (180 days maximum — after that, the same applicant can’t re-reserve it).
Your LLC name must include “Limited Liability Company,” “Limited Company,” “LLC,” “L.L.C.,” “LC,” or “L.C.” and be distinguishable from every entity on the Secretary of State’s records. One Missouri-specific trap: “Ltd.” is prohibited in LLC names — as are “corporation,” “incorporated,” and partnership designators — even though “Limited Company” spelled out is fine. Check the state’s business name search before you file.
Every Missouri LLC must have a registered agent — a person or entity designated to receive legal notices and government documents on behalf of the business at a registered office. The agent must be either a Missouri resident whose business office matches the registered office, or a company authorized to do business in Missouri, with a physical street address in the state (a P.O. box alone doesn’t qualify).
You can serve as your own registered agent if you have a physical Missouri address and can be there during business hours. Many business owners use a professional registered agent service instead — it keeps your personal address off public records and ensures someone is always available to receive documents.
The Articles of Organization is the document that legally creates your Missouri LLC. You file it with the Secretary of State — online through the business filing portal at bsd.sos.mo.gov, or on paper by mail or in person. The gap between the two is unusually wide: online costs $50 (plus a small card fee) and is approved essentially the moment you submit; paper costs $105 and takes several weeks. There’s no expedited tier because online filing already is one.
The Articles must include your LLC’s name, its purpose, your registered agent’s name and Missouri registered office address, whether the company is member-managed or manager-managed, its duration if not perpetual, and the organizers’ names and addresses. Once approved, your documents are downloadable immediately from the portal.
Here Missouri differs from almost every other state: an operating agreement isn’t just recommended — state law requires LLC members to adopt one. It’s still an internal document (never filed with the state), and the statute technically allows it to be oral, but a written agreement is the only practical way to prove you have one. It defines how your LLC is managed: who owns what, how profits are distributed, and how decisions get made.
Your operating agreement should specify whether the LLC is member-managed or manager-managed. In a member-managed LLC, all owners share day-to-day authority. In a manager-managed LLC, a designated manager handles operations while other members retain economic rights. A written agreement is the version that holds up when disputes arise — and in Missouri, it’s also what shows you’ve met the statutory requirement.
An Employer Identification Number (EIN) is a 9-digit federal tax ID issued by the IRS. Your Missouri LLC needs one to open a business bank account, hire employees, and file federal taxes. Applying online at irs.gov is free and issues your EIN immediately after you complete the application.
To use the IRS online application, the responsible party must have a valid Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN), and the business must have its principal place of business in the United States. The IRS does not charge a fee for issuing an EIN.
This section is short by design: Missouri LLCs file no annual report and owe no recurring fee to the state — ever. There’s no renewal, no franchise tax, and no annual LLC tax; Missouri is one of roughly five states with no ongoing report requirement at all. (Missouri corporations do file annual registration reports — the exemption is specific to LLCs.)
What Missouri does enforce is sales tax: before making retail sales you must get a retail sales license from the Department of Revenue — registration is free, but operating without it draws penalties of $500 for the first day and $100 per day after, up to $10,000. The 4.225% state rate is deceptively low; local add-ons bring the average combined rate to about 8.4%, over 10% in some places. There’s no general state business license, though cities like St. Louis and Kansas City require local ones.
The required Missouri state fee is $50 to file the Articles of Organization online (about $51.25 with the card processing fee), or $105 on paper — one of the biggest online-vs-mail gaps anywhere. That’s also the last state fee your LLC ever owes: Missouri has no annual report or recurring charges. Name reservation is optional at $25 for 60 days. There’s no additional state fee to get your EIN; the IRS issues EINs for free.
Yes. Missouri allows a single person to form and own an LLC – this is called a single-member LLC. You can complete the Articles of Organization filing online through the state’s business portal without an attorney, with approval essentially on submission. You’ll still need a registered agent with a physical Missouri address, but that can be yourself if you qualify — and remember Missouri law requires you to adopt an operating agreement, even as the sole member.
No. Missouri charges a $50 Articles of Organization fee online – that’s a required state fee you can’t avoid, though with no annual fees afterward it’s one of the cheapest states over an LLC’s lifetime. What you can avoid is paying extra for formation help. We handle your Missouri LLC filing for $1; you only pay the required state fees.
No – and that’s Missouri’s standout feature: LLCs file no annual report and pay no recurring state fee, one of only about five states where that’s true. Be careful on two fronts, though: don’t pay a third-party “compliance service” to file a Missouri LLC report that doesn’t exist, and don’t confuse the rules — Missouri corporations do file annual registration reports; only LLCs are exempt.
Yes, every Missouri LLC is required to have a registered agent. A registered agent is a person or entity that receives legal notices and official government documents on behalf of your LLC at its registered office. The agent must have a physical street address in Missouri — a P.O. box alone doesn’t qualify — and be available during regular business hours. You can serve as your own registered agent or use a professional service.
The mistakes that come up most often are filing on paper — paying $105 and waiting weeks for what costs $50 and approves instantly online — skipping the operating agreement that Missouri law actually requires, and using “Ltd.” in the company name, which the state rejects. Owners also start selling before getting the free retail sales license (penalties run $500 the first day plus $100 a day), pay compliance services for a nonexistent annual report, and forget the 20% Missouri business income deduction at tax time — it’s separate from the federal QBI deduction and easy to miss.
Online filings through the state’s business portal are approved essentially immediately on submission and payment, with documents downloadable right away. Paper filings take several weeks including mail time. Missouri offers no paid expedited service – there’s nothing to expedite when the online lane is already instant.
