There are three ways to incorporate your business in Missouri:

  1. Hire a lawyer to do the job for you (the most expensive option)
  2. Walk in to the Secretary of State office and do it by yourself
  3. Use a professional incorporation company, like Active Filings.

Missouri Articles of Incorporation Requirements

The Articles of Incorporation is the formation document you file with the Missouri Secretary of State to register your corporation with the state (LLCs file Articles of Organization). In Missouri, you can file Articles of Incorporation by mail, fax, online or in person (it will take the SOS 4 to 7 days to process your filing). If you hire Active Filings to incorporate your business, we are authorized to file online with the state, and we’ll form your LLC or corporation in 1 business day.

To complete your Missouri Articles of Incorporation, you’ll need to include the following information:

Company Name The name shall contain word “corporation”, “company”, “incorporated”, or “limited” or end with abbreviation thereof. The name may not contain any word or phrase which indicates or implies that corporation is governmental agency or that it is organized for any purpose other than purpose for which corporations may be organized under laws of Missouri. The name shall be distinguishable from the name of any domestic or foreign corporation authorized to do business in Missouri or any limited partnership, limited liability company, or reserved name.
Company Purpose List the reason for forming the corporation or the business/activity which the corporation will engage in.
Authorized Shares List the number of shares of corporate stock you are currently authorizing. Technically, this is when you “create” your stock (more can always be authorized later), and that stock will be issued to your shareholders at your first shareholder meeting.
Registered Agent Information In Missouri, a registered agent (also known as a resident agent) is an individual or business that serves as your company’s official point of contact for lawsuits and legal notices. As part of Active Filings’ incorporation service, we include a year of registered agent service when you hire us to incorporate your business in Missouri.
Names and Addresses of the Incorporators The incorporator is the person or company authorized to form the corporation. For example, if you hired us, we would list ourselves as the incorporator. The incorporator does not have any stake in or claim to the corporation being formed.
