How To Start An LLC In Missouri (Apr. 2026) – MO Filing Guide

Forming a Limited Liability Company (LLC) in Missouri is a straightforward process offering business owners flexibility and limited liability protection. The state has relatively low filing fees and simple compliance requirements. For these reasons, Missouri is an accessible state for entrepreneurs looking to establish their business.

To create an LLC in Missouri, you need to submit your Articles of Organization to the Missouri Secretary of State. The online filing fee is $50, whereas the mailing option is $105.

In this article, I’ll guide you through each step on how to start an LLC in Missouri. After reading it, you’ll be able to set up your LLC by yourself.

How To Start An LLC In Missouri

Below is a step-by-step outline you can use to create your LLC in the state of Missouri.

1. Choose Your LLC Name

Under RSMo § 347.020(3) (the Revised Statutes of Missouri), your LLC’s name should be clearly distinguishable from other business names already registered with the state.

You can verify whether your preferred name is available by using Missouri’s Business Entity Search tool. Keep in mind, this search is only an initial screening. The state will officially approve your LLC name only after your formation documents are filed and accepted.

You’ll also need to ensure your name complies with Missouri’s naming rules to avoid rejection.

For detailed instructions on this topic, see my guide on Missouri Business Name Search.

2. Appoint A Registered Agent

Missouri law (RSMo § 347.030.1(2)) requires every LLC to designate and maintain a Registered Agent. This person or organization is authorized to receive legal documents and official correspondence on behalf of the business.

Your Registered Agent needs to meet the following requirements:

• Maintain a physical street address in Missouri (P.O. boxes are not permitted).
• Be available during standard business hours to accept documents.

You can choose one of the following to serve as your Registered Agent:

• Yourself.
• A trusted friend or family member.
• A commercial Registered Agent service or a domestic or foreign entity authorized to operate in Missouri.

Acting as your own agent or nominating someone you know is free. That said, it can lead to availability issues, compliance risks, and privacy concerns. That’s because the agent’s name and address will be displayed on public records. Plus, the nominated person or authority needs to be consistently available during regular business hours to accept legal documents.

For these reasons, I strongly suggest hiring a professional Registered Agent, which usually costs between $150 and $199 annually. These services can assist you by:

• Receiving and forwarding legal and state notices reliably.
• Supplying a compliant Missouri address.
• Maintaining your personal contact details off public records.

3. File Your LLC’s Articles Of Organization

To legally establish your LLC, you need to file the Articles of Organization with the Missouri Secretary of State.

A one-time filing fee is required for this filing, and the amount depends on how you submit your documents:

• For a Missouri LLC online filing of your Articles, the fee is $50, done through the Missouri Online Business Filing System.
• You’ll pay $105 if you complete Form LLC-1 and submit it by mail to the Corporations Division.

For step-by-step filing instructions, refer to my guide on How To File The Articles Of Organization In Missouri.

4. Draft Your LLC’s Operating Agreement

An Operating Agreement is an internal document that outlines how your LLC will operate. It defines the company’s governance rules, along with the rights, authority, and responsibilities of members, managers, and employees.

Under RSMo § 347.081.1, Missouri law requires every LLC to write an Operating Agreement.

That said, this document is not filed with the state or any government agency. Instead, you should keep it with your official business records and update it as your company evolves.

Your Operating Agreement should clearly align with your LLC’s management structure:

• Member-managed LLC: All owners are involved in day-to-day operations and decision-making.
• Manager-managed LLC: One or more appointed managers handle daily operations, while other members remain passive owners.

For detailed instructions on writing and updating this document, refer to my guide on the Missouri LLC Operating Agreement.

5. Obtain Your Employer Identification Number (EIN)

Once your Articles of Organization are approved, you’ll need to apply for an EIN. This nine-digit number is issued by the Internal Revenue Service (IRS) at no cost. Its main purpose is to identify your LLC for federal tax purposes.

Plus, having an EIN is required to:

• Open a business bank account.
• Hire employees and manage payroll.
• File federal tax returns.
• Apply for certain state and local licenses or permits.

After approval, the IRS will issue a confirmation notice known as Form CP 575.

For step-by-step guidance, read my article on How To Get An EIN For Your Missouri LLC.

You can apply for an EIN using one of the following two methods:

6. Get Your Business Licenses And Permits

That said, your LLC may still need specific state, county, or city licenses depending on its business activities and physical location.

Because requirements differ by industry and jurisdiction, both processing times and costs can vary.

I suggest checking with the Missouri Division of Professional Registration to confirm which licenses apply to your business. I would also advise contacting your local city or county clerk to verify this information.

For research resources and guidance, see my article on Missouri Business Licenses.

7. Apply For A Sales Tax License In Missouri

If your LLC sells tangible personal property or provides taxable services, you need to register for a sales tax license. You can do so through the Missouri Department of Revenue.

The state doesn’t charge a fee to register. However, if your LLC operates from multiple locations, you’re required to get a separate sales tax license for each one.

You can register using one of the following two methods:

• Online: Apply through the MyTax Missouri Portal.
• By mail: Complete the Missouri Tax Registration Application (Form 2643) and mail it to the Missouri Department of Revenue.

What To Do After You Form Your Missouri LLC

After the state approves your LLC, you still have to complete a few compliance steps to operate legally in Missouri. Think of the steps below as a practical starting a business in Missouri checklist to help you stay compliant and organized.

1. Open A Dedicated Business Bank Account

Once your LLC is approved and you receive your EIN, you should open a separate bank account for your business.

A dedicated business account helps you:

• Streamline payments and track expenses more easily.
• Build credibility when applying for loans or credit.
• Present a professional image to clients, vendors, and partners.
• Stay compliant with tax and legal requirements while decreasing errors and penalties.

2. Renew Your LLC’s Business Licenses

If your LLC holds business licenses or permits, you need to renew them as required by your industry or local jurisdiction.

Contact the appropriate local agencies and licensing boards to confirm renewal deadlines and comply with guidelines.

3. Pay Your LLC’s Required Taxes

Failure to maintain your compliance status can lead to penalties, fines, or enforcement actions.

a. Federal Tax Requirements

Your LLC needs to comply with federal tax rules. By default, the IRS treats LLCs as pass-through entities, meaning profits and losses flow directly to the owners’ personal tax returns.

• Single-member LLCs generally receive sole proprietorship tax treatment.
• Multi-member LLCs usually get partnership tax treatment.
• LLCs can elect to be taxed as a C corporation or an S corporation if it better fits their tax strategy.

b. State Tax Requirements

On top of federal income tax, you’ll need to remit state taxes.

In Missouri, an LLC taxed as a partnership passes income directly to its members according to their ownership percentages. That said, the LLC itself typically doesn’t pay income tax.

The LLC taxed as a partnership submits the Missouri Partnership Return MO-1065. Individual members report their share of income on their Missouri Individual Income Tax Return (Form 1040).

Additional state taxes may include:

• Sales and use tax on taxable goods and services.
• State income tax withholding for employees.
• Unemployment insurance tax if you hire workers.
• Food and beverage tax, when applicable.

c. Local Tax Obligations

Additionally, your LLC might need to pay city or county taxes. Because local rates vary, the total tax that you pay can differ depending on where your business operates.
