How to Start a Business in Missouri:

When starting a business, the legal entity you choose will have an impact on your taxes, paperwork, personal liability, and your ability to raise funds for your business.

There are several legal structures to choose from:

  • Sole proprietorship: A sole proprietorship is the most basic legal structure, and consists of one individual who assumes all risk for the business.
  • Limited Partnership (LP): A partnership consists of two or more partners who agree to share in all profits, assets, and financial or legal liabilities.
  • Limited Liability Company (LLC): An LLC is the most popular business structure as it protects business owners from personal liability.

Businesses are regulated by Missouri state laws and must be registered through the Missouri Secretary of State website.
