How to Start an LLC in Missouri: Step-by-Step

Learn the steps to form your own LLC in Missouri

Written by Charlotte Lauren – Attorney, updated on

Starting an LLC in Missouri (MO) is an excellent step for new business owners, so long as they understand the correct requirements and costs of setting up this type of business entity.

An LLC is a type of business structure that combines limited liability with the flexibility of a partnership or sole proprietorship. Federal and state pass-through tax treatment also makes it an attractive business entity choice for many Missouri business owners.

Additionally, MO LLC assumes an easy setup process and comes with low annual maintenance costs. So it’s an attractive option for cash-strapped startups and small business owners.

Whether you plan to operate out of this state physically or just register a legal entity, here are the step-by-step instructions to form an LLC in Missouri.

6-Steps to Open an LLC in Missouri

  1. Step 1: Choose a name for your LLC
  2. Step 2: Find/Hire a registered agent
  3. Step 3: File for articles of organization with Missouri Secretary of State
  4. Step 4: Secure an EIN (Employer Identification Number) from the IRS
  5. Step 5: Prepare an LLC operating agreement
  6. Step 6: Open a bank account for LLC

Step 1: Choose a name for your LLC

You should first check if a Missouri LLC name you want is available. Remember, your LLC name has to:

  • Be distinguishable from other MO-registered business names.
  • Include the words Limited Liability Company or an abbreviation like LLC at the end.

You can conduct a business name availability search on the Missouri State of Secretary website using their name search tool. Found an unregistered name? Excellent, to prevent others from registering it, you may want to reserve the name.

Note: Foreign LLCs will also need to search to see if the name that they use is available in Missouri. If not, they will need to register an assumed name in MO and include it in the company formation documents.

An assumed name doesn’t have to be a fictitious name, “provided that the foreign corporation’s actual name shall be used together with its assumed name on documents filed with the Secretary of State. See Section 351.584, RSMo.”

Fictitious name

Domestic LLCs may want to register a fictitious name if they plan to run a Missouri business under a name other than its official corporate name.

It’s also called “Doing Business As” or DBA name. To register a fictitious name, you must submit a filing and pay a $7 state filing fee.

Name reservation for your LLC name

By filing a name reservation form online or by mail, you can reserve the business name for 60 days. The filing fee is $25.

It lets business owners reserve the LLC business name before completing and filing the other documents needed to form an LLC in Missouri.

The business name can be reserved for two additional 60-day periods, up to a maximum of 180 days total. But if the business name reservation runs out, your LLC can still use that name if it is not later used by another business entity.

Step 2: Find/Hire a registered agent

All Missouri LLCs must appoint a registered agent as part of the LLC registration process. The job of a registered agent is to receive service of process documents on behalf of the LLC. Thus, they must be available during regular business hours.

Your registered agent must be a resident in Missouri (or authorized to conduct business in the state of Missouri), have a physical street address in the state, and be capable of handling legal documents.

Business entities can be Missouri registered agents if authorized to conduct business in the state, so long as they meet the other registered agent requirements. You can also be your own registered agent if you meet these requirements.

Missouri lets you use a P.O. Box as the registered office if a physical street address in the same city as what is also listed for the physical street address.

Registered agent service

Some LLCs choose to hire a registered agent service to perform the duties of the LLC’s registered agent.

It’s helpful for foreign LLCs and LLC owners who don’t meet the state requirements. It also may make sense from a cost perspective if someone is not available to receive legal documents during regular business hours.

The costs range from about $40 to $250. Registered agent services are also helpful for business owners who want to keep the privacy of a registered agent’s name and physical street address.

Step 3: File for articles of organization with Missouri Secretary of State

Articles of organization is a cornerstone document indicating the formation of your LLC to the Missouri Secretary of State. Foreign LLCs must also register with Missouri authorities to conduct business in the state.

Articles of Organization costs are the same for domestic and foreign LLCs:

  • $105 if filed by paper
  • $50 if filed online

There is not an official processing time in business days provided at this moment. However, as of October 2021, the state indicates that they are experiencing a longer processing time than normal for online submission.

They also state that paper filings will be processed longer than online applications.

Submitting the filing

To register your LLC online in Missouri, use the Business Registration Online Portal.

Paper filings should be sent to:

State of Missouri, Secretary of State

Corporations Division, P.O. Box 778

600 W. Main St., Rm. 322

Jefferson City, MO 65102

Information to include

The articles of organization should include the following details:

  • LLC’s business name (and an assumed name, if applicable)
  • LLC’s purpose(s)
  • The principal business address of the LLC and its registered agent
  • Name of the registered agent;
  • LLC’s duration
  • Whether the LLC is member-managed or manager-managed
  • Name(s) and address(es) of each LLC organizer

The Application for Registration of a Foreign LLC must include similar information, with a few additions. It must also list the principal address and jurisdiction in which the LLC is organized and a certificate of good standing from that jurisdiction no more than 60 days old.

Note: additional information is also required for a Series LLC.

Step 4: Secure an EIN (Employer Identification Number) from the IRS

An Employer Identification Number (EIN) is a unique tax ID used to identify the LLC on federal tax filings to the Internal Revenue Service (IRS). It may be required to file certain business tax forms with the state of Missouri too.

Not every LLC will need an EIN. Single-member LLC owners can use their social security numbers to file federal and state business taxes. However, if your LLC will have at least one employee, you must have an EIN to submit federal tax filings for employment.

Also, your LLC needs an EIN for sales/excise taxes filings and filings for employee-related withholdings or plans.

You can apply for an EIN online for free. Upon verification of submitted information, you’ll get your LLC’s EIN immediately.

Step 5: Prepare an LLC operating agreement

Missouri statute requires that all LLCs formed or registered in its state have an operating agreement.

However, it’s not filed with the Missouri SOS. It’s an internal document for business records.

An operating agreement is an important document for defining your LLC’s operations.

An operating agreement explains:

  1. Roles and responsibilities of anyone participating in the LLC.
  2. Tax treatment elections.
  3. Membership interests and transferability of such.
  4. Profit and loss allocations.
  5. Rules for the conduct and operations of the LLC.
  6. Voting rules and procedures.
  7. Other operational matters.

Step 6: Open a bank account for LLC

It’s a good business practice to open a business bank account when you are spending and receiving money on behalf of your LLC.

It simplifies accounting, member profit/loss allocation calculations, and taxes. Also, business bank accounts usually provide additional protections beyond personal bank accounts.

Rates and fees will vary based on features and asset holdings. Some of the common documents you’ll need to open a bank account include your LLC’s EIN, formation documents, business license, and ownership agreements.

Missouri LLC costs, taxes, and fees

Missouri doesn’t require LLCs to file annual reports. Hence there are no annual renewal state fees to pay. Sweet right?

As for taxes, LLCs are classified as pass-through entities for tax purposes by default. It means that LLC member(s) report the income and losses from the company on their personal tax return(s).

In some instances, however, Missouri LLC may be responsible for additional state taxes. These include the following.

1. Sales tax

A 4.225% state tax rate is applied to the sale of retail goods in MO or the cost of taxable services.

2. Corporate income tax

By default, a separate corporate income tax is not collected on the LLC entity. However, if the LLC elects for corporate tax treatment, a corporate tax is applied at state and federal levels. The MO state tax rate is 4% as of 2020. The IRS corporate tax rate is 21% as of 2020.

3. Employee taxes

A business with one or more employees needs to withhold taxes from each employee’s paycheck. The MO state tax rate for employees is 5.4% as of 2021. The state tax is in addition to IRS federal income taxes, which are 6.2% as of 2021.

There are also unique tax situations that are described further on the Missouri Department of Revenue webpage.

Missouri business permits and licenses

Missouri doesn’t require a business permit at the state level.

Instead, an LLC will need to check in with all local governments, cities, counties, and municipalities within which the LLC intends to conduct business to determine whether those local government agencies require a business license and the procedure to obtain one.

For instance, Jefferson City requires all eligible companies to apply for a city business license.

For some industries and professions, there may be additional occupational license and registration requirements. The fees vary greatly.

For instance, a real estate agent license costs $62. But architects face a heftier $100 registration fee.

Check with the Missouri Division of Professional Registration for more details.
