Missouri Sales Tax Number

A Missouri Retail Sales Tax number (or Use Tax) is needed if you will be selling at retail or wholesale. Collection of sales tax is required by any business making retail sales in any amount. Retailers should complete Missouri DOR form 2643.

Go to the Missouri Department of Revenue for more information or call at (573) 751-2836 to get a sales tax number or sales tax exemption.

If you sell retail, in any amount, you must have this in order to obtain your City of Chesterfield business license.

  • IMPORTANT NOTE: As of January 1, 2009, it is Missouri State Law for Retail Businesses, or Businesses with any retail sales whatsoever, to submit a "Certificate of No Tax Due" from the Missouri Department of Revenue. A City business license cannot be issued without this document. Contact the Missouri Department of Revenue or call 573-751-9268, for assistance.
