Name Requirements

First, you will need to choose a name that complies with Missouri Secretary of State naming guidelines:

  • Your name must contain the word “corporation,” “company,” “incorporated,” “limited” or an abbreviation of one of these terms.
  • Your name must be distinguishable from any existing business in your state. This includes Missouri reserved names.
  • Your name cannot imply that the corporation is organized for any purpose other than the one outlined in its articles of incorporation.
  • Your name cannot include words that could confuse your corporation with a government agency (FBI, Treasury, State Department, etc.).
  • Your name must contain the word “corporation," “company," “limited," “incorporated," or an abbreviation of one of these.

You can also read the Missouri state statute about corporation naming guidelines for more information.


Name Search With the Missouri Secretary of State

You will need to check name availability by searching the business name database on the Missouri Secretary of State’s website.

This tool is also useful if you decide to register a fictitious name or DBA (Doing Business As) for your company. For detailed information about setting up a DBA for your Missouri corporation, check out our How to File a DBA in Missouri guide.


Name Reservation

If you have a name in mind, but you aren’t ready to officially form your corporation, you can reserve your name. Your business name can be reserved for 60 days (with an additional 60-day renewal possible) by filing an Application for Reservation of Name with the Missouri Secretary of State.

The Application for Reservation of Name form can be filed online with the Missouri SOS Corporations Online Portal, or you can file the form by mail. There is a $25 fee to file your Missouri Name Reservation.


Secure Domain Name

We recommend checking to see if your business name is available as a web domain (URL). Even if you don't plan to make a business website today, you may want to buy the web address in order to prevent others from acquiring it. It’s free to search.

Step 2: Choose a Missouri Registered Agent

When you file your Missouri Articles of Incorporation, you will be asked to give the name of your Missouri registered agent.

A registered agent is a person or entity that accepts tax and legal documents on behalf of your LLC or corporation. Your registered agent can be an individual resident of the state or a company that’s legally authorized to represent businesses in Missouri.

To learn more about registered agents, read our What is a Registered Agent guide.

Step 3: Choose Your Missouri Corporation’s Initial Directors

You must appoint at least one director who, among other things, will oversee your Missouri corporation until the first shareholder meeting.

The directors of a corporation are in charge of the adoption, amendment, and repeal of bylaws as well as the supervision, election, and removal of officers.

Later you will prepare an “Incorporator Statement” with complete names and addresses of each director and keep it in your corporate records book.

Step 4: File the Articles of Incorporation

Now that you have chosen a registered agent and at least one director, it’s time to make your corporation official by filing the Articles of Incorporation form with the Missouri Secretary of State. This document will disclose some basics of your business for the public record, including:

  • Corporate name and statement of purpose
  • Corporate registered agent name and street address
  • Number of authorized shares corporation is allowed to issue
  • Corporation’s effective date and duration
  • Number of directors
  • Incorporators’ names and addresses

Filing Fee: $58 for the first $30,000 in authorized shares plus an additional $5 for every additional $10,000 of authorized shares

Set Up a Corporate Records Book

Think of this as the hard-copy record book where all critical corporate documents are kept, like your Articles of Incorporation, bylaws, meeting minutes, stock certificate ledger, stock transfer documents, etc.


You should keep the corporate records book at your principal location. Corporate records book kits can be purchased online, or you can use a large generic binder to store your records.

Prepare Bylaws for Your Missouri Corporation

Bylaws are the rules that determine how your organization will be governed and run.

You can think about the bylaws as a constitution for your corporation. It makes the rules and priorities clear for everyone involved.

In your bylaws, be sure to include:

  • How the corporation will be governed – the role of directors and officers
  • How meetings are held, voting procedures, electing officers or directors
  • How records will be kept and managed
  • How disputes will be handled
  • How bylaws will be added/amended in the future

NOTE: A corporation’s bylaws will supplement any rules set forth by the federal government or the state.


Ready to get started? Check out these bylaws templates which you can customize to suit the needs of your incorporated business.

Conduct Your First Board of Directors Meeting

An organizational meeting is the first official meeting of your corporation.

These are some of the things that are discussed in a typical organizational meeting:

  • Taking attendance to show you have a quorum (minimum number needed)
  • Appointing temporary officers, chairmen, secretary, etc.
  • Adoption of the bylaws
  • Adoption of conflict of interest policy

Don’t forget to record “minutes” of the meeting and have it signed by all attending directors. Here are some corporate minutes templates to help you get the ball rolling.

Protect Your Assets and Stay Compliant

In order to protect your assets and stay compliant after you start your Missouri corporation, you will need to:

Get an EIN

The Employer Identification Number (EIN), or Federal Tax Identification Number, is used to identify a business entity. It is essentially a social security number for the company.

Why do I need an EIN? An EIN is required for the following:

  • To open a business bank account for the company
  • For Federal and State tax purposes
  • To hire employees for the company

Where do I get an EIN? An EIN is obtained from the IRS (free of charge) by the business owner after forming the company. This can be done online or by mail.

To learn more about EINs, read our What is an EIN guide.

Open a Bank Account For Your Missouri Corporation

There are two critical reasons to open a unique corporate bank account.

The first is that separating your personal assets from your business assets adds another layer of protection in the event that your business is sued.

The second is that syncing a single account with business accounting software will make managing your finances much easier.

Accounting For Your Corporation

It's important to get your books in order, even if you haven't officially opened for business. A well-managed accounting system will help you:

  • Track your business finances, including bills, expenses, and income.
  • Simplify and file your annual taxes.

You can maintain your accounting in two ways:

  • Use a DIY accounting software. This can come with an increased risk of errors especially when starting a new business.
  • Hire an accounting service. They can provide comprehensive advice to help optimize your bookkeeping and taxes as well as additional services such as payroll etc.

Recommended: For most small businesses, we recommend using a reputable accounting service. Schedule a free tax consultation for your business now to avoid costly errors in the future.

Research Business License Requirements

To operate your corporation, you must comply with federal, state, and local government regulations. The details of business licenses and permits vary from state to state, so make sure to research carefully and plan accordingly.

Find out how to obtain necessary licenses and permits for your business or have a professional business licensing service do it for you:

What is an S Corporation?

An S Corporation (S corp) is an incorporated business that is taxed as a pass-through entity. This means that S corps do not pay federal taxes on their business income. Instead, the business profits "pass-through" to the owners of the S corp, who are also known as shareholders. Then, the shareholders pay income tax and report their share of the profits in the form of salaries on their individual tax returns, which are then taxed.


In order to elect an S corporation status for tax purposes, corporations will need to file form 2553 Election by a Small Business Corporation. The form must be signed by all shareholders and must be filed within two months and 15 days after the start of the initial tax year.

To learn more, read our What is an S corporation guide.
