Missouri is the only state in this series where a limited liability company never has to file an annual report, not this year, not ever. That's not an inference from a related statute. It's stated directly on the Missouri Secretary of State's own Corporations FAQ.
Combined with a low filing fee and a state income tax rate that's falling, not rising, it gives Missouri the lowest ongoing compliance burden of any state we've covered so far.
Forming the LLC itself still follows a short, standard process. Here's exactly what that looks like in Missouri, plus what "no annual report" really means once your LLC exists.
TL;DR
- Why Missouri: a $50 online filing fee, no annual report ever, and a state income tax rate trending toward a flat 4.7% make it one of the lower-friction states to form and maintain an LLC in.
- Step 1, name: confirm your LLC name is available with the Secretary of State and reserve it with Form BE-1 if you're not ready to file yet.
- Step 2, registered agent: Missouri requires a physical in-state street address; a PO box alone doesn't satisfy the requirement.
- Step 3, Articles of Organization: file Form LLC-1 with the Secretary of State's Corporations Division; online filing is both cheaper and faster than mail.
- Step 4, EIN without an SSN: founders without an SSN or ITIN apply by phone, fax, or mail using Form SS-4 instead of the online tool.
- Step 5, Form 5472: a 25%+ foreign-owned single-member LLC must file this every year, even at zero revenue, or risk a $25,000 minimum penalty.
- Step 6, ongoing compliance: Missouri LLCs file no annual report, ever, but owners still owe state income tax on pass-through profits at a top rate of 4.7% for 2026.
- Common mistakes: treating the EIN as the finish line and skipping Form 5472 are the two that cost founders the most, in Missouri or anywhere else.
Why Form Your LLC in Missouri?
Missouri's appeal isn't a single standout feature. It's that formation is cheap, the paperwork after formation is lighter than almost anywhere else, and the tax trend is heading in the founder's favor.
- Low formation cost: filing typically runs $50 online, $105 by mail, well under what many states charge.
- No annual report, ever: Missouri's Secretary of State confirms LLCs don't file one, unlike the recurring report-and-fee cycle most states require.
- A falling state income tax rate: the top individual rate sits at 4.7% for 2026 and is set to formalize as a flat 4.7% starting January 1, 2027, with a mechanism for further step-downs tied to revenue growth.
None of that replaces legal or tax advice for your specific situation. It just means the baseline compliance workload in Missouri is genuinely lighter than in most of the states in this series.
Step 1: Choose and Reserve Your LLC Name
Your LLC's name has to be distinguishable from existing businesses registered in Missouri, and it needs to include a designator like "LLC" or "Limited Liability Company."
- Search first. The Missouri Secretary of State's business name database lets you check availability before you file anything.
- Reserve it if you're not ready. Form BE-1 reserves a name for $25, holding it for 60 days.
- Renew twice if needed. A reservation can be renewed twice, for a maximum total hold of 180 days.
- No publication requirement. Missouri doesn't require you to publish a notice of formation in a newspaper, a step some states still impose.
Step 2: Appoint a Registered Agent
Every Missouri LLC needs a registered agent: a person or company with a physical street address in Missouri, available during business hours to accept legal documents and state notices on the LLC's behalf.
- A PO box alone doesn't qualify. The state's own filing form specifies that a PO box may not be used unless a street address is also provided.
- You can serve as your own agent if you have a Missouri street address and can be reliably present during business hours.
- Founders without a Missouri address typically use a commercial registered agent service instead.
Skipping a real agent for a friend's address or an unstaffed mailbox can put the LLC out of good standing with the state.
Step 3: File Your Articles of Organization
Form LLC-1, the Articles of Organization, is the filing that legally creates your LLC. You file it with the Missouri Secretary of State's Corporations Division.
- Filing fee: typically $50 online, or $105 if you file by mail. The paper fee is confirmed directly on the state's own form; the online figure is corroborated by secondary sources.
- Processing time: online filings are generally approved within about 24 hours, while mailed filings can take roughly 3 to 4 weeks.
- No confirmed expedited tier. Missouri doesn't publish a separate rush-processing fee. Filing online is already the fast path, so there's no premium option to weigh against it.
- What it lists: the LLC's name, registered agent, and organizer information.
Once this is approved, your LLC legally exists. That's also when the tax obligations covered in the next two steps start applying.
Step 4: Get an EIN, Even Without an SSN
An Employer Identification Number (EIN) is what the IRS uses to identify your LLC for tax purposes, and you'll need one to open a US bank account or file taxes. It's free directly from the IRS.
Founders with a Social Security Number or ITIN can apply online and get an EIN in minutes. Founders without either use Form SS-4 by phone, fax, or mail instead.
| Method | Who can use it | Typical speed |
|---|---|---|
| Online EIN application | SSN or ITIN holders | Minutes |
| Form SS-4 (phone, fax, or mail) | Founders without an SSN or ITIN | Same-day to several weeks |
The manual route's wait mostly depends on volume and whether the form was filled out completely the first time. A rejected submission means starting the wait over, so getting the responsible-party details right matters more here than in the online flow.
Step 5: File Form 5472 if the LLC Is Foreign-Owned
If your single-member LLC is 25% or more foreign-owned, the IRS requires an annual Form 5472 filing, even at zero revenue. This isn't a Missouri-specific rule. It's federal, and it catches founders in every state who assume a dormant entity has nothing to report.
- Filed alongside a pro forma Form 1120, a placeholder corporate return required with the 5472, even though the LLC itself owes no separate corporate tax.
- Reports transactions between the LLC and its foreign owner, such as capital contributions or payments for services.
- Due on the same schedule as your income tax return, and extensions can typically be requested the same way.
Note: the IRS's stated minimum penalty for a late or missing Form 5472 is $25,000, per form, per year, regardless of whether the LLC made a dollar.
Step 6: Handle Missouri's Ongoing Compliance
This is where Missouri actually separates itself from most of the states in this series. Once your LLC is formed, the state gives it almost nothing recurring to file.
- No annual report, ever. The Missouri Secretary of State's own Corporations FAQ asks directly, "Do limited liability companies have to file an annual report?" and answers "No." Missouri's LLC Act, Chapter 347 RSMo, contains no annual-report provision for LLCs; that recurring obligation applies to corporations under a separate statute, not to LLCs.
- State income tax still applies. Missouri taxes pass-through LLC income at the individual level through its graduated personal income tax, with no separate entity-level LLC tax. The top rate for 2026 is 4.7%, graduated from 2.0%.
- The rate is set to simplify further. Starting January 1, 2027, Missouri's top rate is scheduled to formalize as a flat 4.7%, with a trigger mechanism that could allow further 0.1-point annual cuts tied to state revenue growth.
- A ballot measure is pending, not settled. A proposal to potentially replace Missouri's income tax with an expanded sales tax passed the legislature in April 2026 and heads to voters in November 2026. It's a developing story, not a change you should plan around yet.
Missouri doesn't require you to file an operating agreement with the state, but skipping one is still a mistake. It's the internal document that spells out ownership and decision-making, and it's part of what supports the LLC's liability protection if that protection is ever tested.
Common Mistakes to Avoid
Missouri's light compliance load means there simply aren't many state-specific traps here. That's the point. The mistakes that still show up are the same ones that trip up founders everywhere.
- Treating the EIN as the finish line: for a foreign-owned LLC, it's closer to the starting gun on an annual Form 5472 filing obligation than the end of the process.
- Skipping Form 5472 because there's no revenue yet: the filing requirement doesn't care whether the LLC has made money.
- Using a shortcut for the registered agent: a friend's address or an unstaffed mailbox can put the LLC out of good standing, and Missouri's form explicitly rejects a PO box used alone.

FAQ
Does Missouri require LLCs to file an annual report?
No. The Missouri Secretary of State's own Corporations FAQ states plainly that LLCs don't file an annual report. Missouri's LLC statute, Chapter 347 RSMo, has no annual-report provision for LLCs; that requirement applies only to corporations under a separate law.
This makes Missouri's ongoing compliance load lighter than most states, though you still owe state income tax on the LLC's pass-through profits.
What is Missouri's state income tax rate for LLC owners in 2026?
Missouri taxes LLC income at the individual level through its graduated personal income tax, since the state has no separate entity-level LLC tax. The top rate for 2026 is 4.7%.
It's scheduled to become a flat 4.7% starting January 1, 2027, with a possible mechanism for further small cuts tied to revenue growth. A separate ballot measure that could eventually replace the income tax with an expanded sales tax is pending a November 2026 vote and isn't enacted yet.
How much does it cost to form an LLC in Missouri?
Filing the Articles of Organization (Form LLC-1) typically costs $50 online or $105 by mail, and a name reservation, if you want one, costs $25 through Form BE-1.
Add a registered agent service if you don't have a Missouri street address to use yourself. Missouri doesn't impose a publication requirement, which keeps formation costs lower than in some states.
