How to Form an LLC in Missouri in 7 Steps

A limited liability company (LLC) is a popular legal structure for small businesses. This business structure provides business owners with liability protection and potential tax advantages. One of the main reasons to form an LLC is to protect your personal assets from business liabilities.

LLC formation is easy in Missouri. Just follow along with the six steps in the step-by-step process below to learn how to start an LLC.

Steps to Form an LLC in Missouri


Name Your LLC

You should pick a business name that is unique and that makes your business stand out from the competition. Your Missouri LLC name must be available and must follow the state's naming rules.

Make sure your name is available by doing a business name search on the Missouri Secretary of State Corporations Division website. If there are no matches, you should continue searching for availability by doing an internet screening search. Simply type your desired company name into your favorite search engine to see if there are results.

Also be sure to follow Missouri's naming rules. According to the Missouri Limited Liability Companies Act, your name must contain language to indicate that your company is an LLC. To accomplish this, your name must contain one of the following: limited liability company, limited company, or an abbreviation. Acceptable abbreviations are LC, L.C., LLC, or L.L.C.

Your LLC business name must not include any language that could confuse it with a different type of business entity. So, the LLC name may not include any of the following words: corporation, incorporated, limited liability limited partnership, limited liability partnership, ltd, or any abbreviation of those. Further, your name may not include any language that could confuse your business with a government agency.

If you want to reserve your LLC name before you form your LLC, you can do so by filing a reservation with the Secretary of State online. The filing fee is $25. This reserves your name for 60 days. You can file for two extensions, if necessary.


Get a Registered Agent

registered agent accepts service of process for your LLC. In the event that someone files a lawsuit against your Missouri business, the official documents will go to your registered agent.

Your Missouri registered agent must have a physical street address within the state. They must be available during standard business hours too. A P.O. Box may be listed as a registered office address only if a physical street address in the same city is also listed.

You can be your own registered agent, or you can hire a registered agent service. Using a registered agent service can help business owners maintain privacy and ensure compliance with state requirements by reducing the risk of missing important notices and deadlines.


File Your Articles of Organization

Your LLC is formed by filing articles of organization with the Missouri Secretary of State Corporations Division. Articles of organization form a legal document that contains basic information about your LLC. This document lays out the structure and identifying qualities of your LLC. Under Missouri law, you must include the following information about your business entity when you file articles of organization and start an LLC:

  • The name of your LLC
  • Your LLC's purpose
  • A statement about whether your LLC is member-managed or manager-managed
  • The physical address of your registered office and registered agent
  • The events that would cause your LLC to dissolve, or the duration of your LLC

You can file this paperwork with the Missouri secretary of state online or by mail. If you choose online filing through the business portal, you will need to click “create an account" and follow the prompts. The state fee for filing Missouri articles of organization is $105 for paper filing and $50 for filing a domestic LLC online.

Draft an Operating Agreement

An LLC operating agreement is an internal company document that has a similar purpose to corporate bylaws. Under Missouri law, you must have an operating agreement for your LLC.

You can use this document to form agreements among your LLC members on issues like:

  • LLC management
  • Members' rights and responsibilities
  • Profit-sharing arrangements
  • Voting procedures
  • Tax elections

Your operating agreement can also address any other important company issues. Missouri statutes make it clear that LLC members have the right to negotiate this contract and to form it in the manner that best suits the business.

After forming your operating agreement, you should store it along with your other business records. You do not need to file it with the state.


Get an EIN

Unless you have a single-member LLC with no employees, you will probably need to apply for a federal employer identification number (EIN). An EIN is a unique number that the Internal Revenue Service (IRS) uses to identify companies for tax purposes. You can think of your employer identification number as a Social Security number for your business. Getting an EIN is simple to do on the IRS website. To learn about your federal tax obligations, you can visit the IRS's page on tax information for businesses.

You will need an EIN to:

  • Open a business bank account
  • Get a business credit card
  • Hire employees
  • Apply for licenses
  • File taxes


Set Up Business and Tax Accounts

Your tax and regulatory requirements will vary depending on your location and the nature of your business. To register for state business taxes, you can visit the Missouri Department of Revenue. Depending on the type of business you operate, you may need to pay sales taxes, franchise taxes, unemployment taxes, or other state taxes. Check to see if your LLC is required to register with the Missouri Division of Employment Security for unemployment tax purposes. Also, your LLC may have to carry worker's compensation coverage through the Missouri Division of Workers Compensation.

To find out whether you need local business licenses, you should check with your city and county officials. If you think you may need a federal license, you can visit the Small Business Administration (SBA) website. The SBA's website provides a list of business activities that would require a federal license.


File Beneficial Ownership Information Report (BOIR)

You must file a Beneficial Ownership Information Report (BOIR) with FinCEN after forming a new LLC because of a new requirement. For LLCs created in 2024, this filing must be completed within 90 days from the day your LLC received notice of its creation/registration or 90 days from the day the Secretary of State or other applicable office first provided public notice of your company’s creation/registration, whichever is earlier. If you form your LLC after January 1, 2025, the BOIR filing must occur within 30 calendar days from the date you receive actual or public notice of the LLC’s creation or registration. 

To file your BOIR, visit and select “File BOIR.” To complete your BOIR, you must provide information regarding your LLC, its beneficial owners, and its applicants. Your LLC’s applicants are those who directly filed the document that created or registered the LLC or were responsible for controlling the filing. Beneficial owners are people who have substantial control over the LLC and/or own a minimum of 25% of the ownership interests of an LLC. 

Note: On March 1, 2024, the U.S. District Court for the Northern District of Alabama ruled that the Corporate Transparency Act was unconstitutional. At this time, it is unclear if the federal BOIR requirement will be enforceable. Business owners of LLCs formed before January 1, 2024, may want to wait until closer to the January 1, 2025 filing deadline to check if they must file a BOIR for their business. For LLCs formed in 2024, business owners may want to check right before their 90-day deadline to see if the BOIR requirement is applicable.

Business and Tax Requirements in Missouri

  • Professional licenses
  • Agricultural licenses
  • Environmental permits, certifications, or registrations

Registration in Other States

If you want to do business in another state, you will likely have to apply to register as a foreign LLC. You may need to show a certificate of good standing as part of the application process or otherwise prove your LLC's compliance in its home state.

Annual Filing Requirements in Missouri

Missouri is one of the few states that do not require LLCs to file an annual report or pay an annual fee to the Secretary of State. If you need to make changes to your LLC, you can do so by filing an amendment of articles of organization with the Secretary of State and paying the $25 filing fee.
