Anyone conducting business in the State of Missouri under a name other than their own legal name (e.g., John Doe), must register the business name with the Missouri Secretary of State. Missouri law allows businesses to operate under four forms or organization:
- Sole proprietorship
- Partnership – general and limited
- Corporation – C-Corp; S-Corp; Professional, Not-for-Profit; Foreign Corporation
- Limited Liability Company – LLC
Each structure has its own advantages and disadvantages and there are many modifications and variations within these forms. The key to selection revolves around the concept of liability and taxation. You must decide which of these structures best suits your business. In choosing your business structure, consult with a qualified accountant and/or attorney who are familiar with your resources and objectives.
A description of the forms of organization and some of the advantages and disadvantages are discussed in Legal structures and Starting a New Business in Missouri. Choosing a particular structure does not necessarily determine how the business will be taxed.
The Licenses and registration checklist is a guide to help you with the licensing and registration requirements for starting your new business.
You can download forms on the Web at s1.sos.mo.gov/business%5Ccorporations%5Cforms.asp or contact the Secretary of State’s Office at 573-751-4936.
Understanding the taxes that apply to your business and how to meet the legal requirements of those taxes is critical. Consultation with an accountant or attorney is advisable.
Tax considerations are essential during the formation of a new business and during its entire life. When a business is just starting out, it may have little or no income or assets and the choice of structure may not seriously affect its tax liability. However, as the business grows, the tax implications become more significant.
Doing Business in Missouri: Legal Formation identifies the state and federal forms that must be filed for different business structures and compares the tax liabilities for the most common business structures.
