Your Missouri LLC name must be distinguishable from all existing registered business entities in the state. The name must include "Limited Liability Company," "LLC," or "L.L.C." Certain restricted words (such as "bank," "insurance," and "trust") may require additional approvals from state regulatory agencies.
Search the Missouri Secretary of State business name database to check availability before filing. Many states offer online name reservation for a small fee, which gives you time to prepare your formation documents without losing the name to another applicant.
Every Missouri LLC must designate a registered agent with a physical Missouri street address. The registered agent is responsible for receiving official legal documents, tax notices, and state correspondence on behalf of your LLC. A P.O. Box is not acceptable.
You can serve as your own registered agent if you have a physical Missouri address and are available during regular business hours. Many business owners prefer a professional registered agent service (typically $49 to $150 per year) to maintain privacy and ensure documents are never missed.
File your Articles of Organization (or Certificate of Formation, depending on the state) with the Missouri Secretary of State. The state filing fee is $50. Online filing is available in most states and is the fastest method, typically processing in 5-7 business days.
Your formation documents must include: the LLC name, the registered agent's name and address, whether the LLC is member-managed or manager-managed, and the name and address of the organizer. Some states also require the LLC's principal office address and duration.
While most states do not legally require an operating agreement, having one is strongly recommended for every LLC. An operating agreement defines ownership percentages, profit distribution, voting rights, management responsibilities, and procedures for adding or removing members.
For single-member LLCs, an operating agreement reinforces the legal separation between you and your business, which is critical for maintaining liability protection. Banks and financial institutions frequently require an operating agreement when opening a business bank account.
An Employer Identification Number (EIN) is your business's federal tax ID. Apply free at IRS.gov -- the process takes about 10 minutes and your EIN is issued immediately. You need an EIN to open a business bank account, hire employees, and file federal taxes. Even single-member LLCs with no employees should obtain an EIN for privacy and business credibility.
Keep your business and personal finances completely separate. Open a dedicated business checking account using your EIN and formation documents. This is essential for maintaining your LLC's liability protection and simplifying tax preparation.
Missouri LLCs must meet ongoing compliance requirements to remain in good standing. There is no annual fee, but an annual report must be filed with the Missouri Secretary of State to keep your LLC active. Failure to file can result in administrative dissolution.
You may also need local business licenses depending on your city or county. Check with your local municipality for any required permits or licenses specific to your industry and location.
