Special Missouri Sales Tax Rules

Community Improvement & Transportation Districts

Missouri allows Community Improvement Districts (CIDs) and Transportation Development Districts (TDDs) to levy additional sales taxes. These special districts are common in commercial areas and can add 1-2% or more to the total rate.

Important: CID and TDD taxes are location-specific and can vary even within the same city. Always verify the exact rate for your purchase location.

  • CIDs fund infrastructure improvements, public safety, and business district enhancements
  • TDDs fund transportation infrastructure like roads, bridges, and transit projects

Reduced Grocery Tax

Missouri taxes groceries at a reduced state rate of 1.225% (instead of 4.225%)

Note: The reduced 1.225% rate applies only to the state portion. Local sales taxes still apply at the full rate, so total grocery tax varies by location.

Tax-Exempt Items

  • Prescription Drugs: Medications prescribed by licensed providers
  • Medical Devices: Certain medical equipment and devices
  • Manufacturing Equipment: Machinery used in production
