Business Tax Registration


I am starting a new business in Missouri, do I need to be registered with the Missouri Department of Revenue?

Retail Sales Tax - Any person or company that has a business location in Missouri from which they sell or lease goods or provide a taxable service to a final consumer is required by law to collect and remit Missouri sales tax. It is the taxpayers responsibility to ensure that sales tax is collected at the correct rate. Taxpayers are required to have a Missouri retail sales license prior to making sales. A bond must accompany the application. Any person making retail sales without a Missouri Retail Sales Tax License is subject to a penalty of $500 for the first day of operation and a $100 fine every day thereafter, with a maximum penalty of $10,000. See the penalties defined by Section 144.118. Operating without a license is a misdemeanor and can result in criminal prosecution.

Vendors Use Tax - If an out-of-state vendor makes sales of goods to a final consumer located in Missouri and the vendor has sufficient nexus with Missouri, the vendor is required to collect and remit Missouri Vendors Use tax. The vendor is required to obtain a Missouri Vendor Use tax license and post a bond.

Consumers Use Tax - Missouri cannot require out-of-state companies that do not have nexus or a "direct connection" with the state to collect and remit use tax. If an out-of-state seller does not collect use tax from the purchaser, the purchaser is responsible for remitting the use tax to Missouri.

A seller not engaged in business is not required to collect Missouri tax but the purchaser in these instances is responsible for remitting use tax to Missouri. A purchaser is required to file a use tax return if the cumulative purchases subject to use tax exceed two thousand dollars in a calendar year.

Employer Withholding Tax - Every employer maintaining an office or transacting any business within the state of Missouri and making payment of wages to a resident or nonresident individual must obtain a Missouri employer tax identification number.

Corporate Income Tax :

Corporation Franchise Tax - All domestic corporations and all foreign corporations engaged in business* or qualified to do business** in Missouri must file and/or pay franchise tax. 

*If a corporation has destination sales in Missouri, it is engaged in business in Missouri.

**If a corporation has received a certificate of authority from the Secretary of State, it is qualified to do business in Missouri.

S-Corporations please note:  Qualified subchapter S subsidiaries (QSSS) must file a separate Form MO-1120S and attach their separate balance sheet if they are engaged in or qualified to do business in Missouri.  The return will be filed for Franchise Tax only.

How do I compute the bond?

If you are purchasing a business from a previous owner, the bond should be computed based on the previous owner's sales. If this is a brand new business, you must estimate your average taxable sales for a three-month period.

You can use our Sales/Use Tax Bond Calculator to compute the amount of bond you will need to submit for your Retail Sales Tax license or Vendor's Use Tax license.

Please note: The Department of Revenue uses established bond guidelines based on business location and type in determining if a submitted bond is sufficient to cover sales tax or use tax liability.

How can I be certain that I won't be liable for the previous owner's tax liability?

As a successor/purchaser, you shall withhold a sufficient amount of the purchase money to cover taxes, interest, or penalties due and unpaid by all former owners or predecessors, whether immediate or not, until the former owner or predecessor produce a receipt from the director of revenue showing that all taxes have been paid (a Certificate of No Tax Due or Tax Clearance); otherwise, you shall become personally liable for the unpaid tax, penalty, and interest accrued.

All purchasers have a duty to discover whether taxes are due and unpaid by any former owner or predecessor, whether immediate or not. The lack of knowledge about successorship will not relieve a purchaser from successor tax liability. Reliance on any statement or affidavit stating there were no creditors of the business, also will not relieve a purchaser from successor tax liability.

Below is a list of questions you may want to ask yourself when purchasing an existing business:

  1. Are you purchasing the building (real estate)?
  2. Are you purchasing the inventory?
  3. Are you purchasing the equipment?
  4. Are you purchasing the fixtures?

If you answered "yes" to any of the above questions, please obtain from the seller before you purchase the business either a Tax Clearance or a sales tax Certificate of No Tax due. Request the sales tax Certificate of No Tax due if the seller was responsible for collecting and remitting only sales tax. Request a Tax Clearance if the seller was responsible for collecting and remitting more than one tax type, including sales, use, withholding, corporate income and corporate franchise.

A Tax Clearance must be requested by the previous owner. The previous owner may apply for a Tax Clearance by completing and mailing Form 943 to the Department of Revenue, PO Box 3666, Jefferson City, MO 65105-3666. A Certificate of No Tax due for sales tax can be requested by email at [email protected] or by mail at Department of Revenue, PO Box 3300, Jefferson City, MO 65105-3300. If you have additional questions or comments regarding the purchase of an existing business that were unanswered, please email us at [email protected].
