How to Start an LLC in Missouri: Complete 2026 Guide

How to Form an LLC: Step-by-Step

1. 1

   Choose Your Missouri LLC Name

   Select a unique name ending with 'Limited Liability Company,' 'LLC,' or 'L.L.C.' Search the Missouri Secretary of State's business database to ensure availability. Your name cannot be identical or confusingly similar to existing Missouri entities.

   Pro tip: Consider reserving your name for $25 if you need extra time to prepare your filing documents.
2. 2

   Designate a Registered Agent

   Appoint a registered agent with a Missouri street address who can receive legal documents during business hours. This can be yourself, another person, or a professional service. The agent's address will be public record on your Articles of Organization.

   Pro tip: Professional registered agent services provide privacy and ensure you never miss important legal documents, even when traveling.
3. 3

   File Articles of Organization

   Submit your Articles of Organization to the Missouri Secretary of State online or by mail with the $50 filing fee. Include your LLC name, registered agent information, and management structure. Processing typically takes 5 business days for standard filings.

   Pro tip: Online filing is faster and provides immediate confirmation of submission with tracking capabilities.
4. 4

   Create an Operating Agreement

   Draft an operating agreement outlining ownership percentages, management responsibilities, and operational procedures. While Missouri doesn't require this document, it's essential for multi-member LLCs and provides important legal protections for single-member LLCs.

   Pro tip: Even single-member LLCs benefit from operating agreements to maintain corporate formality and strengthen liability protection.
5. 5

   Obtain an EIN from the IRS

   Apply for an Employer Identification Number (EIN) directly from the IRS website for free. This federal tax ID is required for opening business bank accounts, hiring employees, and filing tax returns, even for single-member LLCs.

   Pro tip: Get your EIN immediately after filing your Articles of Organization - you'll need it for the next steps.
6. 6

   Open a Business Bank Account

   Open a dedicated business bank account using your EIN, Articles of Organization, and operating agreement. This separates personal and business finances, which is crucial for maintaining your LLC's liability protection and simplifying tax preparation.

   Pro tip: Shop around for business banking packages - many Missouri banks offer free business checking for new LLCs.
7. 7

   Obtain Required Business Licenses

   Research and obtain any federal, state, or local licenses required for your specific business activities. Missouri's licensing requirements vary by industry, with some requiring state-level permits while others only need local business licenses.

   Pro tip: Check with your city or county clerk's office for local business license requirements, as these vary significantly across Missouri municipalities.
