If you’re planning to buy a car, truck, or RV in Oklahoma, you’ll need to account for both an excise tax and a sales tax—which together total 4.5% of the purchase price. This tax structure is straightforward but still costly on high-value vehicles. Fortunately, there are legal strategies that allow you to avoid overpaying—saving you thousands at the time of purchase.
In this article, you’ll learn how Oklahoma’s vehicle tax works, how it compares to other states, and how Ride Legal helps buyers keep more of their hard-earned money through proven registration solutions.
Oklahoma Vehicle Sales Tax Overview
Oklahoma applies two separate vehicle-related taxes on purchases:
- Motor Vehicle Excise Tax: 3.25%
- Oklahoma Sales Tax: 1.25%
These taxes are combined for a total of 4.5%, calculated on the vehicle’s actual purchase price, and are due at the time of titling and registration (Oklahoma Tax Commission – Motor Vehicle FAQs).
Additional details:
- Applies to dealer and private-party sales
- Trade-in credits are allowed only on dealer sales
- No city or county vehicle tax applies
Oklahoma does not charge a separate use tax if the vehicle was purchased within the state.
South Dakota Vehicle Sales Tax Overview
South Dakota’s Motor Vehicle Excise Tax (MVET) is set at a flat 4%, charged on the purchase price or fair market value, whichever is higher (South Dakota Department of Revenue – Motor Vehicle Division).
Key facts:
- Applies to dealer and private-party sales
- Paid at time of titling and registration
- Trade-in credits are allowed only when handled by a dealer
- Local municipalities may charge additional small fees, but no local vehicle sales tax
- Applies to passenger vehicles, RVs, trailers, motorcycles, and more

| $50,000 | 4.5% | $2,250 | $52,250 |
| $75,000 | 4.5% | $3,375 | $78,375 |
| $100,000 | 4.5% | $4,500 | $104,500 |
How Oklahoma Compares to Other States
Although Oklahoma’s 4.5% vehicle tax rate is lower than in many states, it still adds up fast—especially when compared to tax-free alternatives.
- California (Los Angeles County): 9.5% – $100,000 = $9,500 tax (California Department of Tax and Fee Administration – Rates)
- Florida (Miami-Dade): 7% with a $5,000 cap – max ~$700 tax (Florida Department of Revenue)
- New York (Yonkers): 8.875% – $100,000 = $8,875 tax (New York Department of Taxation – Sales Tax Rates)
- Montana: 0% – No vehicle sales tax (Montana Department of Justice – Vehicle Registration)
Buyers who register their vehicles in Montana via a legal LLC often save $4,000 to $10,000 or more, depending on the purchase price.
What You Still Pay in Oklahoma
In addition to sales and excise tax, Oklahoma buyers must pay:
- Title fee: $11
- Registration fees: Typically $96 for a new vehicle, decreasing over time
- Insurance verification and any lien recording fees
These fees are relatively minor compared to the tax burden and are consistent with most other states (Oklahoma Tax Commission – Fee Schedule).
