How to Start an LLC in Missouri (2026): Step-by-Step Guide

Published: June 2026 · Updated for the 2026 tax year

Missouri is the state people forget to mention when they argue about the cheapest place to form an LLC — and it might be the most underrated of all. You file once for $50 online, and then, for as long as the company exists, the state asks you for nothing: no annual report, no biennial report, no recurring report fee, ever. This guide walks through every step, what a Missouri LLC actually costs over time (which is genuinely close to zero after formation), the one operating-agreement rule Missouri law makes mandatory that almost every other guide gets wrong, and how to form one from outside the US.

A note from Slava

I'm Slava, co-founder and CEO of Jupid. Before this I co-founded and scaled an AI-powered accounting platform to around $30M in revenue and more than 100,000 business users — the kind of company that ends up filing a lot of paperwork in a lot of states and watching customers trip over the same potholes again and again.

Missouri is the rare state where the potholes are mostly gone. There's no annual report to forget, no recurring fee to get a late notice about, and the filing itself is cheap. That makes it one of the easiest LLCs in the country to keep alive. But "easy" creates its own trap: because the state never sends you a bill or a reminder, two things slip through the cracks. The first is the operating agreement — Missouri is one of the few states that legally requires one (most "how to start an LLC in Missouri" articles say it's "recommended," which is wrong), and people skip it precisely because the state never asks to see it. The second is that the headline "$50" is the online fee; mail the paper form and it's $105.

So this guide does what the others skip: it spells out the real (and refreshingly small) cost over time, it gets the operating-agreement requirement right, it covers the non-resident path, and it hands you a dated checklist for your first 90 days. Everything here is current for 2026, with links to the official sources so you can verify before you file.

Should you actually form your LLC in Missouri?

If you live in Missouri and run your business from Missouri, this is easy: form your LLC in Missouri. It's cheap to start, free to maintain, and you avoid the trap of forming somewhere "fancier" and then having to register back into Missouri as a foreign LLC — which means a second set of fees, a second registered agent, and the other state's recurring costs on top. For a Missouri-based business, forming anywhere else is almost always a net loss.

Missouri is also a quietly strong pick for a particular kind of out-of-state founder: someone who genuinely operates everywhere and nowhere (a remote, online business with no single physical home base) and wants the lowest possible ongoing burden. Missouri's combination of a low filing fee and zero recurring state filings beats most "popular" states on maintenance. The honest caveat is that Missouri is not a no-income-tax state the way Wyoming or Nevada is — it taxes income through your personal return — so if your only goal is to escape state income tax, look elsewhere. If your goal is the least possible paperwork and the lowest recurring cost, Missouri is hard to beat.

If you're weighing the trade-offs, our best state to form an LLC tool walks through them, and our Wyoming LLC guide covers the no-state-income-tax, privacy-focused case in detail. For most people reading this, though, the answer is Missouri — here's how.

How to start an LLC in Missouri, step by step

1. Choose and check your LLC name

Your name has to include "Limited Liability Company," "Limited Company," "LC," "L.C.," or "LLC" ("Limited" can be shortened to "Ltd." and "Company" to "Co."), and it has to be distinguishable from every other entity registered in Missouri. Search the Missouri business entity search before you get attached to anything. Want ideas or want to test a few options at once? Our Missouri business name generator is built for exactly that. If you want to lock a name in before you're ready to file, an Application for Reservation of Name (Form BE-1) holds it for 60 days for $25 — and you can renew it up to a 180-day maximum.

2. Appoint a Missouri registered agent

Every Missouri LLC needs a registered agent who can accept legal papers and official notices on its behalf. That agent is either an individual who actually lives in Missouri with a physical street address, or a business entity authorized to do business in Missouri — a P.O. box only works if a real street address is also provided. You can serve as your own agent if you're a Missouri resident with a street address; the agent's name and address become public record on the Articles, which is one reason people who'd rather keep a home address private (and everyone who lives out of state) hire a commercial registered agent for roughly $100–$150 a year.

3. File the Articles of Organization (Form LLC-1)

This is the step that creates your LLC. The cheapest and fastest route is to file online through the Missouri Business Filings portal for $50 — online submissions are usually processed in about a business day. If you'd rather file the paper Form LLC-1, you mail or fax it to the Corporations Division, and the fee is $105 (the form itself says so). You'll list the LLC name, the purpose, the registered agent and address, whether the company is member-managed or manager-managed, and the organizer's name and signature. Once it's approved, download or save the stamped copy — your bank will ask for it.

4. Adopt your operating agreement

Here's where Missouri differs from most states. Missouri law — RSMo 347.081 — says the member or members of an LLC "shall adopt an operating agreement." This isn't a recommendation; it's the statute. You don't file it with anyone, and the state won't ask to see it, but you're legally expected to have one, and you'll need it anyway to open a bank account. It sets out ownership percentages, how profits are split, who can make decisions, and what happens if a member leaves. A single-member LLC needs one too — "member or members" includes you — and it's part of how you keep the liability shield intact.

5. Get your EIN from the IRS

An EIN is your LLC's federal tax ID, and you need it to open a bank account, hire anyone, and file taxes. It's free. Apply at irs.gov — if you have an SSN or ITIN, the online application takes a few minutes. If you don't (common for non-resident owners), file Form SS-4 by fax or mail with "Foreign" written on the responsible-party line — don't invent a number; see the non-resident section below. Never pay a third party for the EIN itself — the number is always free from the IRS.

6. Register for Missouri taxes and any local licenses

Forming the LLC doesn't cover your tax registrations. If you sell taxable goods or services with Missouri nexus, register for a sales/use tax license with the Missouri Department of Revenue (through the MyTax Missouri portal); Missouri also requires a bond for new sales-tax accounts. If you'll hire employees, register for withholding with the DOR and for unemployment insurance with the Missouri Department of Labor. There's no statewide general business license, but some cities have their own rules — Kansas City and St. Louis, for example, both levy a 1% local earnings tax — so check the city where you operate via openforbiz.mo.gov. And any professional or industry license you'd need as a sole proprietor, you still need as an LLC.

7. Skip the annual report — there isn't one

This is the easiest step in any state guide: there's nothing to do. Missouri does not require LLCs to file an annual or biennial report, and there's no recurring report fee. (The registration report you may have read about is a corporate requirement.) Once you've formed, your ongoing list is short — keep your registered agent active, keep clean books, and calendar your federal and Missouri income-tax filings. That's it.

What a Missouri LLC really costs, year by year

Most guides quote "$50 and you're done" — and for once that's nearly true. Here's the fuller picture, including the part the "$50" headline hides.

Year one

Every following year

The number nobody else leads with: $0 a year. In California a formed-and-idle LLC still owes $800 every year; in Delaware it's $300. In Missouri, once you've filed, the recurring state cost of keeping the LLC alive can be exactly zero. That's the whole reason Missouri belongs in the "cheapest states" conversation — not the formation fee, which several states beat, but the maintenance cost, which almost none of them do.

The thing the "$50" headline hides. The $50 figure is the online fee. The paper Form LLC-1 costs $105 — more than double — so unless you have a reason to file on paper, file online. It's cheaper and it's processed in about a day instead of a week.

DIY versus a formation service versus Jupid. Doing it yourself costs the $50 online fee and your time. A formation service charges $0–$300 on top of that (the "$0" packages still pass through the $50 and then upsell you a registered agent and a "compliance" subscription you mostly don't need in a no-annual-report state). Jupid forms your Missouri LLC for free — you pay only the state filing fee — and then handles the bookkeeping and tax filings afterward, which is where the real ongoing effort lives once the state stops asking you for anything.

Forming a Missouri LLC as a non-resident or foreign founder

You can own a Missouri LLC without being a US citizen or resident — Missouri imposes no residency requirement on members or managers, and its zero-annual-report rule makes it appealingly low-maintenance from abroad. The practical hurdles are a Missouri agent, an EIN, a US bank account, and the right federal filings.

Registered agent. If no member or manager lives in Missouri with a real street address, you must use a commercial Missouri registered agent. Budget around $100–$150 a year. P.O. boxes and mailbox-store addresses don't qualify on their own.

Getting an EIN without an SSN. The IRS online EIN tool requires the responsible party to have an SSN or ITIN, so foreign founders generally can't use it. Instead, file Form SS-4: on the line asking for the responsible party's SSN/ITIN/EIN, write "Foreign" — don't invent a number. Submit it by fax or mail, or call the IRS international EIN line (it's not toll-free). Check the current Form SS-4 instructions for the right fax number, since the IRS changes it; fax turnaround is usually a few business days, phone is immediate. The EIN is free.

ITIN. An ITIN (Form W-7) is a tax ID for individuals who aren't eligible for an SSN. Your LLC gets an EIN; you as an owner may separately need an ITIN only if you personally have to file a US return. Owning the LLC and opening a bank account usually don't require one. ITINs are issued with a tax return attached or through an IRS Certifying Acceptance Agent and can take a couple of months.

The Form 5472 obligation — don't skip this. A single-member LLC owned by a non-US person is a "disregarded entity" that generally must file Form 5472 along with a pro-forma Form 1120 every year, reporting transactions between the LLC and its foreign owner — even with zero income. This is an information return, not an income-tax return, and the penalty for missing it is $25,000. A foreign-owned multi-member LLC files Form 1065 instead. Almost no Missouri LLC guide mentions this; build it into your annual calendar from day one.

US bank account. Most traditional US banks want the owner physically present to open a business account, along with the EIN confirmation letter, the filed Articles of Organization, the operating agreement, and a passport. Several fintech business-banking platforms onboard non-resident-owned US LLCs remotely — eligibility and policies change, so check current terms before you rely on any of them. This tends to be the most friction-prone step.

Missouri tax. There's no franchise tax and no annual report to worry about. But if the LLC earns Missouri-source income, a non-resident member can have a Missouri nonresident income-tax filing, and the LLC may have Missouri withholding or composite-return obligations for nonresident members. Federally, if the LLC is engaged in a US trade or business, the foreign owner has US filing obligations of their own (Form 1040-NR for an individual, plus the Form 5472 filing above). A US cross-border CPA is worth the consultation here.

Registered agents and the Corporate Transparency Act (BOI)

Your registered agent is the person or company designated to receive lawsuits and official notices for the LLC. In Missouri it has to be a state resident with a physical street address or a business entity authorized in Missouri — and because the agent's address is public on your Articles, plenty of Missouri residents hire a commercial agent purely to keep their home address off the record.

On the federal beneficial-ownership side: under the Corporate Transparency Act, LLCs were originally required to file a Beneficial Ownership Information (BOI) report with FinCEN. That changed. FinCEN's interim final rule, published in March 2025, redefined a "reporting company" to mean only entities formed under foreign law that register to do business in a US state. As of early 2026, that means a Missouri-formed LLC — even one with foreign owners — has no BOI filing obligation. Older articles still tell you to "file within 30 days"; that's now wrong for domestic LLCs. FinCEN has said it intends to finalize the rule, so this could shift; check fincen.gov/boi before you assume one way or the other. (If you register a foreign-formed entity to do business in Missouri, that entity may still have a BOI deadline.)

Your first 30, 60, and 90 days

Days 1–7

• Get your EIN from the IRS (free; online if you have an SSN/ITIN, otherwise by fax or mail with "Foreign" on the responsible-party line).
• Adopt your operating agreement in writing — Missouri law requires it, and you keep it with your records.
• Check your BOI status. As of early 2026 a domestic Missouri LLC has no FinCEN filing to make; re-verify at fincen.gov/boi.

Days 1–30

• Open a US business bank account (EIN letter, filed Articles, operating agreement, ID).
• Register with the Missouri Department of Revenue for sales/use tax if you sell taxable goods, and for withholding if you'll hire.
• Register with the Missouri Department of Labor for unemployment insurance if you'll have employees, and set up federal payroll.
• Check city requirements where you operate — Kansas City and St. Louis both levy a 1% earnings tax and may require a local business license.
• Get any professional or industry licenses your work requires, and look into business insurance.

Days 30–90

• Set up bookkeeping and keep personal and business finances strictly separate — that separation is what holds up the limited-liability shield.
• If you're a foreign-owned single-member LLC, put the annual Form 5472 + pro-forma 1120 filing on your calendar now.
• Decide on federal tax classification — default (disregarded/partnership) versus an S-corp election (Form 2553), typically worth modeling once profit clears roughly $40k–$50k. A multi-member or S-corp-electing LLC can also look at Missouri's SALT-parity (PTET) election on Form MO-PTE.
• Calendar your income-tax deadlines. There's no annual report to track in Missouri — your only recurring obligations are your federal and Missouri income-tax filings and keeping the registered agent active.

Common mistakes with Missouri LLCs

Skipping the operating agreement because "Missouri doesn't ask for it." Why it hurts: it's actually required by RSMo 347.081, and without one your LLC runs on the statute's default rules — which may not match what you and any co-owners intended, and a bank usually won't open an account without it. Fix: adopt a written operating agreement the same week you form, even as a single member.

Assuming the "$50" is the only way to file — then mailing the paper form. Why it hurts: the paper Form LLC-1 costs $105, more than double the online fee, and takes about a week instead of a day. Fix: file online through the Missouri Business Filings portal unless you have a specific reason not to.

Treating Missouri like a no-income-tax state. Why it hurts: people pick Missouri for "no fees" and then are surprised by Missouri income tax on their pass-through profit. Missouri has no franchise tax and no annual report, but it does tax income through your personal return. Fix: budget for state income tax the way you would in any taxing state; the savings here are in maintenance, not income tax.

Forming in Missouri while operating somewhere else — without registering there. Why it hurts: if you actually do business in another state, you generally have to register the Missouri LLC there as a foreign LLC and follow that state's rules; skipping it can mean penalties and an inability to enforce contracts. Fix: form where you operate, or register as a foreign LLC in every state where you have real presence.

Letting the registered agent lapse. Why it hurts: because Missouri never sends an annual-report reminder, it's easy to forget the one thing you do have to maintain — a valid registered agent — and a lapsed agent can lead to administrative dissolution. Fix: keep the agent current and update the SOS record if your agent or address changes.

Frequently asked questions

How much does it cost to start an LLC in Missouri in 2026? Filing the Articles of Organization online costs $50. Filing the paper Form LLC-1 by mail or fax costs $105. There's no annual report fee in Missouri, so for a Missouri resident acting as their own registered agent, $50 can be the entire state cost to form and maintain the LLC. A non-resident adds a commercial registered agent, typically $100–$150 a year.

Does a Missouri LLC have to file an annual report? No. Missouri does not require LLCs to file an annual or biennial report, and there is no recurring report fee. The annual registration report you may have read about applies to corporations, not LLCs. This makes Missouri one of the cheapest and lowest-maintenance states to keep an LLC in good standing.

Is an operating agreement required for a Missouri LLC? Yes. Missouri is one of the few states that legally requires it — RSMo 347.081 says the member or members of an LLC "shall adopt an operating agreement." You don't file it with the state; you keep it with your records. Even a single-member LLC needs one, and it's part of how you keep the liability shield intact.

Can a non-US resident own a Missouri LLC? Yes. Missouri has no citizenship or residency requirement for members or managers. You'll need a commercial Missouri registered agent and an EIN (which you can get without an SSN by filing Form SS-4). If you're the sole owner, the LLC must file Form 5472 with a pro-forma Form 1120 every year — the penalty for missing it is $25,000.

Does Missouri require LLCs to publish a formation notice in a newspaper? No. Unlike New York, Arizona, Nebraska, Georgia, and Pennsylvania, Missouri has no newspaper publication requirement for LLCs.

How long does it take to form an LLC in Missouri? Online filings are usually processed in about one business day. Paper filings by mail take roughly four to seven business days, and fax filings about one to three days. Missouri doesn't sell an expedited tier for LLCs, but because online filing is already near-instant, you rarely need one.
