Oklahoma car sales tax rules

  • Tax type: Vehicle excise tax (3.25%) plus 1.25% sales tax
  • Rate used in the calculator: 4.5%
  • Local taxes: Vehicle purchases are not subject to city or county sales taxes.
  • Trade-in credit: Partly. The 3.25% excise tax is on the price before the trade-in; the 1.25% sales tax is on the price after it.
  • Manufacturer rebates: Not confirmed by the state source; the calculator taxes the price before the rebate, the more cautious choice.
  • Also note: The total is 4.5% on a new car with no trade-in. Used cars follow a separate excise formula.
