How to Register a Business Name in Missouri

Registering your business name in Missouri is a key step in starting your business. The process ensures your chosen name is unique and legally associated with your business entity.

Step 1: Choose Your Business Name

• Check Name Availability: Use the Missouri Secretary of State’s online business name search tool to verify that your desired name is not already in use by another registered business.
• Comply with Naming Rules: Avoid names that are misleading or imply a different business type than yours. Certain words may require additional permissions or licenses.

Step 2: Register Your Business Entity

• For Corporations, LLCs, and Partnerships: Register your business entity name when filing your formation documents with the Missouri Secretary of State. This officially registers your business name at the state level.
• Filing Online: Missouri allows online filing for business formation, which speeds up the registration process and provides immediate confirmation.

Step 3: Register a Trade Name (Doing Business As - DBA)

• For Sole Proprietors or Businesses Using a Different Name: If your business operates under a name other than your legal entity name, you must register a trade name (DBA) with the Missouri Secretary of State.
• DBA Registration: File the assumed name certificate online or by mail. This registration is valid for five years and can be renewed.

Additional Operational Considerations

• Licensing and Permits: After registering your business name, check local city or county requirements for business licenses or permits that may be tied to your business name.
• Tax Registration: Register your business with the Missouri Department of Revenue for state tax accounts using your registered business name.
• Recordkeeping: Maintain copies of all registration documents and confirmations for compliance and future reference.

As of 2026, these steps reflect Missouri’s current business registration process. Always verify specific requirements on the Missouri Secretary of State’s website or consult with a business operations advisor to ensure compliance.
