How to Form an LLC in Missouri
Forming a Missouri LLC means filing Articles of Organization with the MissouriSecretary of State, getting an EIN from the IRS, and appointing a registered agent. Here's exactly how it works — and how to have it done for you.
How to form an LLC in Missouri, step by step
- Choose your Missouri LLC name
Pick a name that's available in Missouri and meets the state's naming rules — it must include "LLC" or "Limited Liability Company" and be distinguishable from existing businesses.
- Appoint a registered agent
Every Missouri LLC must have a registered agent with a physical address in the state to receive legal and government mail. You can be your own agent or use a service.
- File your Articles of Organization
Submit your formation documents to the Missouri Secretary of State along with the $51.25 state filing fee. This is the step that officially creates your LLC.
- Get your EIN from the IRS
Your federal tax ID — needed to open a business bank account, hire employees, and file taxes. It’s free directly from the IRS.
- Create an operating agreement
Not always required by the state, but strongly recommended: it sets out who owns and runs your Missouri LLC and helps protect your liability shield.
- Open a business bank account
Keep business and personal finances separate. Bring your formation documents and EIN to open the account.
LLC or C-Corp in Missouri?
Most solo founders and small businesses in Missouristart with an LLC — it has simple taxes, light paperwork, and solid liability protection. If you plan to raise venture capital or issue stock options, investors usually expect a C-Corporation (often formed in Delaware). If you're not sure, an LLC is the common starting point, and you can change structure later as your business grows.
