The formulas

  • Sales tax = sale x (4.5% + local rate)
  • Nexus when counted sales are at least $100,000 in the preceding or current calendar year
  • Counted sales = direct sales + marketplace sales on which the facilitator did not collect

How it works

Figures current as of November 2026.

The state rate is 4.5 percent. The tool multiplies the sale amount by the statewide base rate plus the local rate you enter (county and city sales 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 Oklahoma must register and collect once it has at least $100,000 of taxable sales of tangible personal property into Oklahoma in the preceding or current calendar year. Marketplace sales on which the facilitator collects Oklahoma tax do not count toward your own threshold; marketplace sales on which it does not collect do count.

A seller with a physical presence in Oklahoma, 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.
