Sales Tax Guide for Missouri

What Is Taxable in Missouri?

In Missouri, tangible personal property is generally subject to sales tax. However, there are notable exemptions, such as prescription drugs, select groceries, certain medical devices, and certain agricultural equipment.

If your business sells taxable goods or services, it’s essential to collect and remit sales tax correctly. Furthermore, check if use taxes apply when purchasing out-of-state products.

Who Needs to Collect Sales Tax?

Businesses that need to collect sales tax in Missouri include:

  • Retailers with a physical presence in Missouri
  • Online sellers who meet the state’s economic nexus threshold
  • Service providers offering taxable services

Missouri enforces an economic nexus threshold of $100,000 in sales annually. Exceeding this limit, even without a physical presence in Missouri, requires registration to collect sales tax. Failing to do so may result in penalties and back taxes, thus doola’s Bookkeeping service is ideal for staying compliant and avoiding legal issues.

  2. Visiting the Missouri Department of Revenue website.
  3. Completing the online application process.
  4. Receiving your Missouri Sales Tax License to start collecting sales tax.
