Oklahoma Car Sales Tax Calculator
Estimate the 3.25% Motor Vehicle Excise Tax on a vehicle purchase. The tax is calculated on the net price after deducting the trade-in value.
What Is the Oklahoma Car Sales Tax?
Oklahoma doesn’t use a standard sales tax for vehicles. Instead, it charges a 3.25% Motor Vehicle Excise Tax on the car’s net price.
Here’s what that means in plain terms:
- Vehicle Price: The total price of the car before discounts.
- Trade-In Value: If you trade in your old car, its value is subtracted from the price of the new car.
- Taxable Amount: Vehicle Price – Trade-In Value.
- Excise Tax: 3.25% of the Taxable Amount.
For example:
If you buy a car for $35,000 and trade in your old one for $10,000, the taxable amount is $25,000. The excise tax will be $812.50 (3.25% of $25,000).

Tips for Car Buyers in Oklahoma
- Trade-In Matters – Always check how much your dealer offers for your old car. Every dollar reduces your taxable amount.
- Other Fees Still Apply – Don’t forget about title fees, registration costs, and documentation fees. These are separate from the excise tax.
- Budget Ahead – Before walking into the dealership, run the numbers with the calculator. It keeps you in control of the negotiation.
- Used vs. New Cars – The 3.25% tax applies to both new and used vehicles, as long as the purchase is from a dealer.
