Critical steps in the planning process

  • Register the name of your business with the Secretary of State (866-223-6535) by filing the necessary forms and paperwork. The way to register a name is different for each type of legal structure. Choices of Legal Structures are sole proprietorship, partnership, limited partnership, Limited Liability Company (LLC), or corporation. A discussion of the issues involved in the legal formation of your company can be found in Doing business in Missouri: Legal formation. Each legal structure has unique registration requirements, which are outlined below:

    To check on the availability of a business name, you can search the Secretary of State’s database online at: https://sos.mo.gov/BusinessEntity/soskb/csearch.asp.

  • Obtain local business licenses through the city or county government (generally this is the city clerk or county clerk).
  • A sales tax number or use tax is needed if you will be selling at retail. Collection of sales tax is required by any business making retail sales. Those businesses buying wholesale or operating solely as a wholesaler should complete a Form 149 Sales/Use Tax Exemption Certificate (see: dor.mo.gov/forms/149.pdf) and provide it to their supplier. Go to the Missouri Department of Revenue site at: https://dors.mo.gov/tax/coreg/index.jsp or call at 573-751-5860 to get a sales tax number or sales tax exemption.
  • Federal Identification Number (EIN). Generally required only when you have business partners, hire employees, form a corporation or LLC; however, your bank may require and EIN to open a business account. Go to the IRS website at irs.gov/pub/irs-pdf/fss4.pdf to get form SS4.
