How to Register an LLC in Missouri (2026 Filing Guide)
To register an LLC in Missouri, you file Articles of Organization (Form LLC-1) with the Missouri Secretary of State through the Online Business Filing System. The filing fee is $50 online or $105 by mail. Online filings are typically processed the same day, while mail filings take about 3 to 4 weeks. Missouri is one of the few states that legally requires every LLC to adopt a written operating agreement, though you keep it internally rather than filing it with the state. You will also need an EIN from the IRS and a registered agent with a physical Missouri address. Missouri has no annual report requirement and no franchise tax, making it one of the least expensive states to maintain an LLC long-term.
AnyWhereFormations handles this filing end to end for founders who would rather not manage state portals and deadlines themselves. Below is the full process if you want to understand each step, or to file it yourself.
What You Need Before You File
- A business name that is distinguishable from every other entity on record with the Missouri Secretary of State and includes “limited liability company,” “LLC,” or an approved abbreviation
- A registered agent with a physical Missouri street address (a P.O. box can be listed in addition to a street address in the same city, but never alone)
- A decision on member-managed versus manager-managed structure
- The name and address of an organizer to sign the filing
- A payment method for the $50 online filing fee
Steps to Register a Missouri LLC
1. Check name availability
Search the Missouri Secretary of State’s business entity database to confirm your desired name is distinguishable from existing businesses on record under Missouri Revised Statutes Section 347.020. Changing only the entity designator is not enough to make a name distinguishable from an existing one. Words implying a government connection or a different entity type, such as “Corporation,” are prohibited, and terms tied to licensed professions may require proof of licensure. You can reserve a name for 60 days for $25, renewable twice for up to 180 days total.
2. Appoint a registered agent
Missouri requires every LLC to maintain a registered agent with a physical Missouri street address, available during normal business hours to accept legal documents. This can be yourself, another member or manager, or a commercial registered agent service, which keeps your personal address off the public record and matters most for founders who do not have a Missouri address, including international founders. Missouri does not require the agent to sign a separate consent form, but confirm their willingness to serve before listing them.
3. File the Articles of Organization
Submit Form LLC-1 online through the Missouri Secretary of State’s Online Business Filing System, or by mail to the Corporations Division in Jefferson City. You will list the LLC name, a brief business purpose, registered agent information, organizer name and address, principal office address, management structure, and duration (perpetual or a specified end date). The fee is $50 online, with online filings typically processing the same day, or $105 by mail, which takes about 3 to 4 weeks.
4. Adopt an operating agreement
Missouri is one of the few states that legally requires LLC members to adopt an operating agreement under Missouri Revised Statute Section 347.081. It is not filed with the state, just kept with your internal business records, but skipping it is a compliance gap, not just a missed best practice. It should cover ownership percentages, voting rights, profit and loss allocation, management structure, and dissolution procedures. Single-member LLCs need one too, since without it the LLC can look like a sole proprietorship in a legal dispute, and sole proprietorships carry no liability protection.
5. Get a federal EIN
Apply for an Employer Identification Number directly from the IRS at no cost, after your Articles of Organization are approved since the IRS will ask for your formation date and state. Multi-member LLCs always need one; single-member LLCs need one only if they elect corporate tax treatment or hire employees. Founders without a US Social Security Number can still get an EIN by submitting Form SS-4 by fax rather than through the online IRS system.
6. Register for Missouri state taxes if applicable
Register with the Missouri Department of Revenue using Form 2643 through the MyTax Missouri portal, at no cost. If your LLC sells taxable goods or services, register for a Missouri Retail Sales Tax license. If you have employees, register for employer withholding and unemployment insurance. Missouri imposes no franchise tax or entity-level income tax on pass-through LLCs; profits flow to members, who pay Missouri’s flat 4 percent individual income tax rate on their share.
7. Open a business bank account
Keep business funds separate from personal funds to preserve your LLC’s liability protection. Banks typically ask for your Articles of Organization, operating agreement, and EIN confirmation.
8. Maintain compliance, no annual report required
Missouri does not require LLCs to file an annual report, so there is no recurring state filing fee just to stay active. Your main ongoing obligation is keeping your registered agent current; if your agent or address changes, file a Statement of Change within 30 days for a $10 fee. Failing to maintain a registered agent is grounds for administrative dissolution.
How Long Does Missouri LLC Approval Take?
Online filings through the Missouri Secretary of State’s portal are typically processed the same day, with confirmation issued immediately. Mail filings take about 3 to 4 weeks once received, in addition to mailing time, and cost more. Filing online is both cheaper and dramatically faster in Missouri, so there is little reason to file by mail unless you have a specific reason to.
Foreign Founders and International Applicants
Missouri does not require an LLC owner or organizer to be a US citizen or Missouri resident. International founders commonly use a commercial registered agent for the required in-state address and apply for an EIN by fax using Form SS-4 rather than the SSN-gated online IRS application. Missouri also allows anonymous LLC formation: member names are not required in the public Articles of Organization, only the registered agent’s information becomes part of the public record, which is a meaningful privacy advantage for founders who prefer to keep ownership details off public databases. AnyWhereFormations manages both the registered agent setup and EIN process directly for non-resident founders.
