Quick Steps to Starting a Business

Step 1

First, research your business. Consult with state and federal government resources and other professionals, such as an accountant, attorney, financial adviser, and other experts for advice regarding your business.

Step 2

Next, register your business with the State of Missouri.

  • Create a business entity
  • Obtain a Federal Employer Identification Number (EIN)
  • Register for required state taxes, including unemployment tax, where applicable
  • Register with other Missouri agencies if required in your industry

To ensure that you have the information needed to successfully complete your registration, please use our Business Registration Checklist PDF file.

Step 3

If necessary, register for a business license, permits, and other taxes with local city or county.
