If you formed your corporation in one state but are doing business in Missouri, you'll need to complete the Missouri foreign corporation registration process under RSMo §§ 351.572–351.587. This involves specific forms, fees, and compliance steps with the Missouri Secretary of State.
Missouri calls this filing a Certificate of Authority, rather than a foreign registration, but the concept is generally the same. You’ll need to apply for this certificate and appoint a registered agent in order to be legally authorized to conduct business in the state.
Under RSMo §§ 351.572–351.587, all companies foreign to Missouri–that is, businesses formed in other states or countries—must file for a Certificate of Authority with the Missouri Secretary of State. Here’s a quick checklist to get you started:
Before registering your foreign corporation in Missouri, ensure your corporate name meets state requirements and isn't already taken by another business. For foreign corporations registering in Missouri, your name does not need to include terms like 'Corporation,' 'Company,' 'Incorporated,' or their abbreviations, but it must be distinguishable from other names on record.
The state won't approve names suggesting government affiliation or official endorsement. Your name also needs to be distinguishable from existing businesses in Missouri's records, even if you're using this name legally in other states.
Use the Missouri Secretary of State's Business Entity Search tool to check if your name is available. This free database shows potential conflicts immediately, allowing you to coordinate your Missouri naming strategy with your broader corporate identity.
If your name is available, you can secure it for 60 days by filing the required application with a $25 fee. The reservation may be renewed as needed, but name reservation cannot exceed 180 days in total. This reservation gives you time to complete the rest of your Missouri foreign corporation registration while aligning with registration timelines in other states.
When your established corporate name is already in use in Missouri, you can file a fictitious name registration. This allows you to do business under a different name in Missouri while maintaining your original legal name in your home state and other jurisdictions. The fictitious name must still follow Missouri's naming rules and be different from existing businesses.
Your foreign corporation must have a registered agent in Missouri before filing for your Certificate of Authority. Under RSMo § 351.370, this agent needs a physical Missouri address. This ensures the state can deliver legal documents and official notices to your corporation.
Your registered agent serves as your official point of contact in Missouri. If you don't name a registered agent, the state can administratively dissolve your business under RSMo § 351.486, effectively ending your right to operate in Missouri.
You must maintain your registered agent continuously and notify the Secretary of State of any changes using Form Corp-59, which carries a $10 filing fee.
Missouri requires a Certificate of Good Standing from your home state before approving your registration. This document confirms your corporation is current on all filings, taxes, and fees in its state of incorporation.
Check whether your certificate is currently valid and accepted by the Missouri authorities at the time of your filing, as Missouri does not specify a 60-day requirement for a Certificate of Good Standing. Contact your home state's Secretary of State office to request this document..
Don't wait until the last minute. An outdated certificate guarantees rejection by the Missouri Secretary of State, forcing you to restart with a fresh certificate. The 60-day window includes weekends and holidays, so plan carefully to ensure successful registration, especially when coordinating multiple state filings simultaneously.
You have three filing options, each with different processing speeds.
Regardless of your chosen method, maintain copies of everything you submit and track your application until you receive your Certificate of Authority.
After successfully completing your Missouri foreign corporation registration, ongoing maintenance keeps your business in good standing.
Maintaining good standing preserves your corporation's ability to enter contracts, defend lawsuits, and operate legally within the state. Companies that neglect compliance requirements face increasing penalties and potential forfeiture of their Certificate of Authority. The key is implementing systems to track deadlines and ensure timely filings throughout your corporation's lifecycle in each jurisdiction.
Your most critical ongoing obligation is filing the Annual Registration Report each year by the end of the month in which your corporation was incorporated or, for foreign corporations, qualified to do business in Missouri. You can file online for $45 or by paper for $65, as established by the Secretary of State's office. Unlike some states, Missouri doesn't send reminder notices, so incorporating this deadline into your compliance calendar is essential.
Late annual reports incur a $15 penalty for each 30-day period they are late, and persistent non-compliance leads to administrative forfeiture of your Certificate of Authority. Once forfeited, you'll lose your legal standing to conduct business until completing the reinstatement process, which involves additional fees and potential complications with contracts and business relationships established during the period of non-compliance.
Local requirements add another layer of compliance for multi-jurisdiction businesses. Kansas City and St. Louis maintain their own business licensing systems separate from state registration. Each municipality where you conduct business may have specific licensing requirements, necessitating research for each operating location.
Missouri business taxes
Most foreign corporations need three primary tax registrations in Missouri.
Can my corporation operate while the filing is pending?
Don't start conducting business until you receive your approved Certificate of Authority. Operating beforehand triggers penalties and legal complications that aren't worth the risk, especially for companies managing compliance across multiple jurisdictions. Online processing is typically fast, so you likely won't wait long for approval.
How to change our corporate name after registration?
File Form Corp-53 (Amendment to Certificate of Authority) with the required fee. If your new name differs from what's registered in your home state, you'll also need a fictitious name registration. For businesses operating in multiple states, check name availability through the Business Entity Search tool before filing to avoid rejection delays that can complicate your multi-state operations.
Do we need a Missouri business license?
Your Certificate of Authority permits operation, but industry-specific licenses may still apply. Cities like Kansas City and St. Louis require separate local business licenses. Multi-jurisdiction businesses should develop a comprehensive licensing matrix for each state and municipality where they operate rather than assuming blanket coverage.
Can we use a P.O. Box for the registered agent?
Missouri requires a physical street address where your agent can receive legal documents during business hours. P.O. Boxes don't meet this requirement since process servers need to deliver documents to an actual person at a real location. Businesses operating across multiple states should maintain a database of registered agent requirements for each jurisdiction.
