Oklahoma's excise and sales tax on vehicles
Service Oklahoma collects an excise tax of 3.25% of the purchase price or taxable value and a sales tax of 1.25% of the actual purchase price when you title a vehicle, unless an exemption applies.[1] Its title-transfer instructions say: do not subtract the amount given for a trade-in from the purchase price.[1]
| Case | Tax | Share of price |
|---|---|---|
| $28,000 car, $6,000 trade | $1,260.00 | 4.50% |
| $40,000 truck | $1,800.00 | 4.50% |
| $9,000 used car | $405.00 | 4.50% |
Trade-in and the sales tax partA 2023 change may let the 1.25% sales tax be figured on the price minus a trade-in; we could only see that in a summary, not the rule itself, so the calculator follows the title instructions and taxes the full price. The difference is 1.25% of your trade-in value.
Disabled veterans can be exempt on one vehicle every three years.[1]
