The formulas

  • Sales tax = sale x (4.225% + local rate)
  • Nexus when counted sales are more than $100,000 in the preceding 12 months, tested at the end of each calendar quarter
  • Counted sales = direct sales + marketplace sales

How it works

Figures current as of November 2026.

The state rate is 4.225 percent. The tool multiplies the sale amount by the statewide base rate plus the local rate you enter (local sales or use tax for the delivery address) and shows the state and local parts separately. The local rate depends on where the goods are delivered.

A seller with no physical presence in Missouri must register and collect once it has more than $100,000 of gross receipts from taxable sales into Missouri in the preceding 12 months, tested at the end of each calendar quarter. Sales you make through a marketplace facilitator count toward your own Missouri threshold, together with your direct sales.

A seller with a physical presence in Missouri, such as staff, an office or inventory, must collect regardless of the threshold. The tool does not decide whether a product is taxable or exempt; enter the taxable price.
