Trade-ins, rebates, and incentives are not taxed in Oklahoma
Trade-in credit is deducted from the taxable price of the vehicle you’re purchasing in Oklahoma.
For example: You’re buying a new Ford F150 at a dealership in Tulsa for $39,000, and the trade-in value of your old Dodge Ram is $3,600. You’ll only pay the combined 4.5% tax rate on $35,400 of your new truck purchase.
Oklahoma works differently from many other states in that sales and excise taxes are calculated on the purchase price after any other rebates or incentives are applied to the price.
That means that if the above new vehicle scenario also included a cash rebate of $1,000, you’d only be taxed on $34,400 of your new truck’s sales price.
How to calculate sales tax on a car in Oklahoma
Calculating taxes in Oklahoma is quite simple for a new car purchase:
- Multiply your car’s final purchase price by 0.045 for your total tax cost.
But things can get a bit confusing when dealing with a used car purchase:
- Subtract $1,500 from the purchase price of your used car.
- Multiply the remaining price by 0.045.
- Add the result to $20 for your total tax cost.
