How to Start an LLC in Missouri

Missouri offers a simple and affordable LLC formation process, with a $50 filing fee to submit your Articles of Organization with the Missouri Secretary of State. The state processes filings in 5-7 business days, and Missouri does not require LLCs to file an annual report, which significantly reduces ongoing compliance costs. Missouri has a top income tax rate of 4.8%, and the state’s business-friendly environment makes it an attractive place to form an LLC.

Follow these steps to start your Missouri LLC in 2026.

How to Start an LLC in Missouri (6 Steps)

Step 1: Name Your Missouri LLC

Your Missouri LLC name must be distinguishable from any other business entity on file with the Missouri Secretary of State. The name must include a designator such as “Limited Liability Company,” “LLC,” “L.L.C.,” “LC,” or “L.C.” You can search for available names using the Missouri business entity search.

If you find an available name and aren’t ready to file immediately, you can reserve it for 60 days by filing a Name Reservation with the Secretary of State for $25. This prevents anyone else from registering the same name while you prepare your formation documents.

Before finalizing your name, check whether the matching domain name is available for your website and whether the name is available on social media platforms. You should also search the USPTO trademark database to make sure your desired name doesn’t infringe on an existing trademark.

Missouri naming rules:

• Must include “Limited Liability Company,” “LLC,” “L.L.C.,” “LC,” or “L.C.”
• Must be distinguishable from other business names on file with the Secretary of State
• Cannot include words that imply the LLC is a bank, insurance company, or government agency without proper licensing
• Cannot contain language suggesting a purpose the LLC is not authorized to pursue

Step 2: Choose a Registered Agent

Missouri requires every LLC to have a registered agent with a physical street address in Missouri. The registered agent receives legal documents — including lawsuits, subpoenas, and official state correspondence — on behalf of your LLC. This is a legal requirement, and your LLC cannot be formed without designating a registered agent.

You can serve as your own registered agent (if you have a Missouri address), appoint a trusted friend or family member, or hire a professional registered agent service. While acting as your own registered agent saves money, it means your personal address becomes public record and you must be available at that address during all normal business hours to accept documents.

Our top recommendation is Northwest Registered Agent ($39/year), which also handles LLC formation for $39 + the $50 state fee. Using a professional service provides privacy, ensures you never miss an important document, and frees you from having to be physically present at a fixed address during business hours.

Step 3: File Your Articles of Organization

To officially create your Missouri LLC, you need to file Articles of Organization with the Missouri Secretary of State. The fastest way to file is online through the Secretary of State’s online filing system. You can also file by mail, but online filing is recommended for faster processing.

When completing the Articles of Organization, you’ll need to choose between a member-managed and manager-managed structure. In a member-managed LLC, all owners participate in running the business. In a manager-managed LLC, one or more designated managers handle day-to-day operations while other members are passive investors. Most small LLCs choose member-managed.

Filing details:

• Filing fee: $50
• Online filing: Missouri Secretary of State (recommended)
• Processing time: 5-7 business days (standard)

Information required:

• LLC name
• Purpose of the LLC (can be general, such as “any lawful purpose”)
• Registered agent name and address
• Principal office address
• Management structure (member-managed or manager-managed)
• Organizer name and address
• Duration of the LLC (typically perpetual)
• Effective date (can be a future date)

Step 4: Create an Operating Agreement

Missouri does not legally require an operating agreement, but having one is strongly recommended for every LLC, whether single-member or multi-member. An operating agreement is an internal document that establishes the rules for how your LLC is run, including ownership percentages, profit and loss distribution, voting rights, and what happens if a member wants to leave or if the LLC is dissolved.

Without an operating agreement, your LLC will be governed by the default rules in the Missouri Revised Statutes (Chapter 347), which may not align with your intentions. For example, the default rules assume profits are split equally among members regardless of their capital contributions. An operating agreement lets you customize these terms. Most banks and financial institutions also require a copy of your operating agreement before they will open a business bank account.

Step 5: Get an EIN

Apply for an Employer Identification Number (EIN) through the IRS website. It’s free and takes about 15 minutes online. An EIN is a nine-digit number assigned by the IRS that acts as your LLC’s tax identification number — think of it as a Social Security Number for your business. You need an EIN to open a business bank account, hire employees, file federal taxes, and apply for business permits. Even single-member LLCs with no employees should get an EIN, as it helps keep your personal Social Security Number off business documents.

Step 6: Comply with Missouri Tax and Licensing Requirements

Missouri does not require LLCs to file an annual report, which is a significant advantage that simplifies ongoing compliance. However, Missouri LLCs are still subject to state income tax. Missouri has a graduated income tax with a top rate of 4.8%, and LLC profits passed through to members are taxed at the individual member level.

If your LLC sells taxable goods or services, you’ll need to register for a Missouri sales tax license through the Missouri Department of Revenue. Depending on your industry and location, you may also need local business licenses or permits. Check with your city or county government to determine specific licensing requirements.

While there is no annual report, you should keep your registered agent information current with the Secretary of State and file amendments if your LLC’s name, registered agent, or other key information changes. Maintain accurate internal records, including your operating agreement, meeting minutes, and financial statements.

Missouri LLC Costs

Total first-year cost: $50-$350. This range covers the required state filing fee ($50) and an optional registered agent service. Because Missouri does not require an annual report, ongoing costs after the first year are limited to your registered agent service and any applicable taxes. Missouri is one of the most affordable states for LLC formation and maintenance. See our complete guide to LLC costs by state.

Missouri LLC Taxes

Missouri has a graduated state income tax with a top rate of 4.8%. The tax brackets start at 2% and increase incrementally. LLC profits pass through to members’ personal tax returns and are taxed at these individual rates. LLCs are treated as pass-through entities for tax purposes, meaning the LLC itself does not pay state income tax — instead, profits flow through to the members’ personal tax returns.

Missouri does not impose a separate franchise tax on LLCs. This is an advantage compared to states like Texas and Tennessee that impose franchise or excise taxes on businesses in addition to (or instead of) an income tax.

Missouri has a state sales tax rate of 4.225%, with local jurisdictions adding their own taxes for a combined rate that typically ranges from 5.1% to 10.85% depending on your location. If your LLC sells taxable goods or certain services, you’ll need to collect and remit sales tax. Register through the Missouri Department of Revenue.

Remember that all LLC members still owe federal income tax and self-employment tax (15.3%) on their share of LLC profits, regardless of the state’s tax treatment.

Missouri LLC Annual Requirements

Missouri does not require LLCs to file an annual report, which makes it one of the simplest states for ongoing LLC compliance. This saves you both time and money compared to states that charge annual report fees. However, you must still keep your registered agent information current with the Secretary of State and file amendments if your LLC’s name, registered agent, or other key information changes.

Maintain accurate internal records, including your operating agreement, meeting minutes, and financial statements. Missouri LLCs must file state income tax returns with the Department of Revenue. If you collect sales tax, you must file sales tax returns on the schedule determined by the Department of Revenue (monthly, quarterly, or annually based on your sales volume).

If you want to confirm that your LLC is in good standing, you can request a Certificate of Good Standing from the Secretary of State for $10. This document is sometimes needed when applying for business loans, opening bank accounts in other states, or registering your LLC as a foreign entity in another state.
